Although there are two kinds of fabrics use for making our body fitted dress such as knitted fabric and woven fabric and these fabrics are prepared from different counts of yarn. Furthermore there are more than twenty two kinds of fabric are use in making wearer dress and some of them are ironic fabric,skin fabric and mirror thread fabric. As someone speak knitted fabric or woven fabric,his or her meaning is at what type of machinery is use for manufacturing such kind of fabric. Yes knitted fabric is fabricate on " knitting machines" and " woven fabric is prepare on "looms machines"where verticals and horizontal lines yarn flow run sides by side and fabrication process complete but in the manufacturing of knitted fabric"circular knitting machines operates in the shape circle"maybe the worldwide famous name " hosiery" derived from word "hose" which mean " hallow tube" because knitting fabric is manufacture in a tubular way,like a tube and like a hose( enternal side empty tube but with much of elasticity). Yes now not go for away and watch the outlets of internal side of building of a knitwear garments stitching unit where for putting off water when fire break inside then factory. Hosiery is a premise where production of knitted fabric are produced and raw materials use are " hose type fabric" yes so only name indicate that hosiery products are knitt fabric products. Now about the knitted fabric,one word mostly use is " knot" which mean in very simple words is " twist some type of yarn,threads or long card with each in such a way as a knot appear for feeling of our hands"so in knitt fabric only " knots go forword to fabricate the patch of some length long hose of fabric" yes knitted fabric consist of series of regular knots and these knots are not so strenghty but due to these knots there are much elasticity in knitted fabric and yes dues to such best property knit fabric products are widely use and like by many people through out worldwide. More than half of men,women,kids and nascent are warp with some kinds of knitwear garments dresses. It is our common observation"knitwear garments are more selling product then woven and non woven fabric products. But in our modern world where new scientific inventions bring revolution in human life same is true with " knitt fabric products as are in these days available from clothing and ready made garments in worldwide markets. So when demands of knitt fabric products increase then production started at industrial level for providing the knitwear garments stitch and sew products to customers and buyers then at more profit gain these products sell to consumers. Those countries where raw materials of knitt fabric was available in large and extra amount try to export such knitwear garments products to those countries where demands and consumption of such type of ready made knitwear garments products was higher,sell such products at more profit and bit by bit these business transshaped in to import and export trading. So some countries of the world specialized in such knitwear garments stitching products and now those countries of the world are exporting knitwear garments stitching products to others countries of the world where demands of such products are higher than homeland need base.
Quality of knitt fabric sewing products start from the start of first stitching operation of a garments where at the starting time quality related technetions and knitwear garments stitching specialists and accessories attaching experts are present on the sold in stitching flow. Raw materials for producing output of knitwear garments presents there and stitching machines are adjust in row by stitching master as already arranged stitching machinery with the help and guidelines of industrial engineers. In knitwear garments stitching flow machines are manage and arrange in such a way as " first sewing operation attach with others part of garment at first stitching machine" and skilled stitching machines operators holding sets for sewing garments parts and attaching accessories as per operation of instructions set by garment technetions head and industrial engineers head of department.
Following things as " tools for starting new flow for stitching garment are present there",
Machines,for stitching and sewing garments parts stitching machines like over lock, flats lock,lock stitch, button hole machine, button hole attaching machine, threading machines, cutter for cutting the credo of knitt fabric,bar take machines, and all others kind of sewing and stitching machines as require for starting new output at first time from a new knitt fabric garment stitching flow. It all methods,requirements are need base such as simple style T-shirt sewing flow can be start with only fifteen stitching machines but when complex articles and models arrive in knitwear garments stitching flow then stitching machines are arrange and manage as per sample requirements. Although there are large numbers of machines already present there in knitwear garments stitching flow because some type of faulty and out of order machine remove and replace suddenly till there will be less difference of output as are targeted during managing time period. So large numbers of extra machines are present in machines store from where any time extra needed stitching machine can request or faulty machines can replace with working stitching machines. Remember,stitching machines store operates under the control of chief engineer of mechanical department head,who one control, monitor and issues stitching machines requirements as per job export orders. Stitching machines are fundamental unit of a knitwear garments sewing units. If there are faulty and old machines are use for sewing of knitwear garments products then quality conditions will be poor and worse then the sewing and stitching quality of new and modern stitching machinery.
Knitwear garments stitching and attaching accessories. There are many types of stitching accessories thats are attach with knitwear garments parts but,because job order of export nature are presold so only those garments accessories are buy from out sides as are the demands of customers but in some large size knitwear garments export firm there are arrangements for preparing and manufacturing all kinds of " knitwear garments stitching accessories" at inside premise. There are many garments attaching accessories and a very long list can be written for nominating and enlisting purposes but all these knitwear garments stitching accessories depends on the requirements, as what type of garment accessory improved the related and reascent customer. So as already samples are improved from customers and buyers,and all accessories are stalk in the main store for further issuing to relevant stitching unit or units. There are three types of fundamental and basic accessories and these are parts of every knitwear garments. Such as threads,labels and needles.
Although someone new learner of knitwear garments stitching, stitching quality skill and accessories attaching techniques can be divide in to two different groups for further and for easiness such as " all those garments thats are directly attach with fundamental and basics accessory such main label and side labels containing washing care instructions,composition of fabric contents" but there are many many others different types of accessories such as button,draw cards, eyelits,fusing, ribbons,embroidery, printing and different colours patches as attach on knitwear garments for decoration purpose. Yes for more easiness knitwear garments accessories cab be distribute in to stitching accessories and packing accessories. Yes there are also a very long list of packing accessories such as poly bags,prices tags,dracards for attaching prices tags with main or with back neck label or some else place with the body of knitwear garments, sizes tags as these size tags are attach for distinguishing size difference, light weigh papers for separating different knitwear garments layers during folding, hangers for hanging a knitwear garments for safe and sound health, Small size poly bags for packing separate and each knitwear garment piece, there on small size written instructions set for suitable and proper care of knitwear garment piece and cartons of different dimension. Remember all packing accessories are order to purchase from "packing accessories markets" as the requirements and demands of customers and buyers. For example, there are only some importing firms and companies that demand for attaching"alarms and security tags with every pieces of knitwear garments" and some importing and purchasing knitwear garments products send some type of packing accessories for attaching with different knitwear garments during packing time.
Till as we are talking about" knitwear garments attaching and stitching different types of accessories" but first come as first so we turn again at our real point of discussion and that important point for our real talk is " How different knitwear garments stitching accessories attach with garment during stitching operations in a inlines flow?".
"Where and with what part of a knitwear garment different accessories are sew during stitching process?".
What is differences between garment accessories and trims?, elaborate with examples and details with sketches and call outs?.
Write the names of twenty knitwear garment attaching accessories and also basic composition of contents ?.
But before answering these questions with details,first and foremost we try to explore the " knitwear garment stitching accessories details with examples and attaching placements. Yes attaching placement " where to attach there accessories on knitwear garment during stitching process on stitching machines in stitching flow lines.
All knitwear garments stitching and attaching accessories details will describe here in up coming posts and pages,but only little and suitable"accessories terminologies" will describe for general purpose skill,knowledge and for fundamental information. As mention above lines about knitwear garments stitching and attaching accessories that these accessories at different places on knitwear garments during stitching and sewing process. Again for instance think about the "HTL",heat transfer label in knitwear garments where this" label attach and why this labor attach on knitwear garments at back neck side instead attaching woven or paper lable or attaching a patch of same knitt fabric. Remember details study stuff about " heat transfer label" will provide to new learners of knitwear garments technology later in these blog posts and blog pages,because very long and lengthy details study posts and pages need much time consumption so we try to leave till our experts write about all details and study stuff of/about " heat transfer lable" yes both about "heat transfer machine and composition of heart transfer lable". More so for further reading and understanding about " why such type of heat transfer lables are stick fast with the back side of knitwear garment?".
It is the duty of quality supervisor and inlines quality inspectors to inspect the quality of heat transfer lable time to time by matching standards with improved gold or read seal sample and study all others instructions,guidelinesas and quality tips as are provided by quality manager,quality assistant manager,garment technologist,merchantdiser and head of washing department. Some details stuff will be available to quality supervisor and inlines quality inspectors on technical package but others instructions for attaching heat transfer able all senior level quality authorities provide as oral and verbal so for achieving the quality of heat transfer cable" as per improved red tag sample" quality supervisor and quality inspectors must monitor and check time to time " as the standard of customer improved red tag sample" and quality supervisor and quality inspectors must try to reduce the rejection percentage to minimum level. Inspectors must check the heat transfer machine heat transfer figures and note on per hour quality report but if during working hours some kinds of deviation occur in " heat transfer machine temperature, pressure and in transferring lable on knitt fabric surface then loosing a single moment tell about the machine defects and faults to mechanical engineer, electrical engineer and heat of quality department. Although heat transfer lable quality process are very complex because at one time many variables are ready and present for monitoring, checking and for controlling. Yes some of all them are as under,
Heat transfer machine heat and temperature amount and quality. Setting temperature on heat transfer machine at first time when knitwear garments attaching this operation reach" heat and temperature are adjuste accordance with manufecturing instructions as those are written on the cartons of heat transfer labels contain in", Yes before opening the carton of HTL, please first and foremost study the all precautions and instructions about" setting temperature on heat transfer machine" and if further guidelines need then connect and contact with senior level authorities of quality department. Second thing for rememberance is setting " pressure on heat transfer machine" because without property set bar of pressure during attaching of heat transfer lable on the knitwear garments the quality of HTL decrease and targeted quality level will not achieve, so for adjusting of the pressure of heat transfer machine read carefully all instructions set " as are written on heat transfer lable containing lable" be note and be carefully here only little error or negligency can damage the whole quality of the heat transfer lable. So reducing rejection percentage and for saving yourself from humiliation be careful during attaching of heat transfer lable on knitt fabric garments body.
Third and most important factor while attaching heat transfer lable is the " operator of heat transfer machine" who one operate this machine skillfully without some any hesitation" because as evey one know that " only practice make the men perfect" yes same is true with this heat transfer machine operator w one control and operate this machine. Skill of machine operator is fundamental success key for improving the "attaching quality of heat transfer lable" such as if operator is skillfull and has some experience then quality achieving process become easy and targeted set quality improve bit by bit during the work flow of this important operation.
There are many type of minor,major and critical defects and faults of HTL that transverse shape in to ugliness look, so be active,alert ,careful and must be aware with such type of defects and faults during attaching on HTL machine. Some of them are as under,
Centre out of HTL while pasting it on back neck sides on a knitwear garments pieces. If during first instance when HTL machine operator reverse the knitwear garment neck for center sign if little error occur or hand tremble then " there will be no centre of back neck of garment" so if center is out of placemen then attaching of HTL center will be out. So improving hand on practicing center for attaching and pasting HTL on knitwear garment is first,forest and fundamental responsibility of quality supervisor and inlines quality inspectors whos are monitoring and controlling the quality of HTL. Placement is very critical and crucial point of attention during pasting of HTL on heat transfer machine because" HTL must be attack at the back neck center of knitt fabric garments", and if back neck center out of position and rejection chances of that garment increase and create chances of humlitation for quality personals. So during attaching of HTL on heat transfer machine improving hands of operator is the duty and responsibility of quality supervisor and inline quality inspectors. Four sides dimensional are are arrowed on call out or on the sketch of knitwear garment lay out in tech pak papers,so study that stuff and then start the attaching of HTL lable on heat transfer machine. Here it is important point for attention is" wrong size attaching of HTL lable on garment pieces" is a blinder and such faults and defects can cause first rejection percentage increase then removing and washing of this wrong size or damage lable process are time consuming and wastage of" washing chemicals",yes more cause of humiliation is appearance and look of reattach HTL decrease shape of garment.
Written words on HTL papers must check with careful focus of attention because sometimes some words are missing or there are errors of spelling of words and remember these errors can reject the garment piece. Although there are special age limit for every lot of heat transfer lable. So be careful while attaching HTL on heat transfer machine, first study and be not the " manufacturing date of the HTL labels" and if there passed the nighty day then stop the operations of attaching HTL labels and soon inform to the quality supervisor and assistant manager of quality for further actions. But if these manufacturing date is correct and fall under nighty days time period that is the age limit of HTL labels, then allow the heat transfer machine operator to start the attaching of HTL as per sample.
Insome knitwear garments stitching and exporting firms" there are disciplines and principle for arranging preproduction meeting on HTL attaching" and in those preproduction meeting senior level authorities of quality department provide guidelines about the attaching of HTL on heat transfer machine. Where quality relate people gather there and write all instructions on diaries and write on papers all instructions for future uses and improving the Quaker of attaching HTL.
How to guide and improve heat transfer machine operator to attach HTL at the center back neck of garment?.
How to take " corrective and preventive actions" if there defects and faults appears or present in garment pieces?.
HTL lable provide many different kinds of instructions set such are there "whashing care sign and symbols", " Composition of knitt fabric "such as yarn composition, accessories composition and about trims composition percentage information", and " how care about the garment during steam ironing",.
But the main intends of attaching heat transfer lable on knitwear garments is this lable remain in active conditions till the one dozen washing turn of garment and this lable attaching objectives are the publicity of brand. Although it equivalency is same as with advertising intends so HTL must remain in active state with the washing turn time period decrease its shiness till at some stage of age HTL show dimness and with the passage of long run time period, disappear from the back neck of the knitt fabric garments. But during this interval complete all intends and objectives of publicity in wide range of population as increasing the wants and demands on market for consumers and for buyers.
Here where I am completing my probation period of nighty day there many different style with many different knitted fabric garments are produce with HTL, yes all styles of under wear" both upper underwear and lower or bottom wear" all garments are attach with HTL. Even all sandows are attach with HTL at the back side neck.

During attaching or pasting of heat transfer lable on the back neck of a knitt fabric garments many precautions and care must bear in mind set such as "the pading surface must be on all sides at smooth level otherwise pressure forcing upper side falling pad can't touch smoothly and properly on lower side bed pacing where precenter back neck of knitwear garment piece is place for pasting the HTL, so if there are such type of ups and down in other words calibration of heat transfer machine is not correct then HTL quality standard must be mismatch with preaprove sample. So in this wrong attaching way quality standard will not achieve and there will be greatest losses of time period, money and energies. So heat transfer machine proper working is must for the continuation of smoothly producing knitt fabric output on time with best type of quality full products.
Quality supervisor and inlines quality inspector must watch machine standard and hang a " standard HTL card on heat transfer machine as signed by top level quality department authorities and production related authorities and there are hand written instructions about "heat transfer machine calibration"such as setting machine temperature, adjusting pressure and duration of time period to revolving and moving upside pressure paid stay on HTL lable for the transference of chemical with specific heat amount that paste the written stuff on the back neck knitwear garment surface.
Yes ,while checking, monitoring, improving and controlling the quality of the heat transfer lable first properly check the placement on improve red tag sample then start first output of garments attach with heat transfer lable. First some pieces transfer to "quality audit department" for further improving quality of heat transfer lable because quality audit members inspects every aspect of heat transfer lable with reference with the customers and buyers improved samples garments and foreword some essential and important suggestions for further improving quality especially displacement of the HTL, distance from back neck credo tape,about the contents of knitt fabric contents and also raise concerns if there are errors and shortcoming in the quality of heat transfer lable. If some kinds of changes must be need in further production then written commonds obey and changes will apply on heat transfer lable.
One important task for inlines quality supervisor and inlines quality inspectors is to complete "Corrective actions+preventive actions",yes what about these two terms and what detail study suggests about these two terms in the " knitwear garments industry?".
Remember, In knitwear garments industry these words are abbreviate as "CAPA", in some simple words and for easy understanding about these two famous words,someone can explain in this way,as there are huge possibilities of errors and wrong doing work in all operations during stitching and sewing machines and not exemption the heat transfer lable from these defects and faults. It mean if work of heat transfer lable attaching continuation live for long run then there are much chances for " wrong size attaching of HTL on the back neck of some garment pieces" of some kind of fault appear in the heat transfer machine", " How a quality inspector can improve the quality of the attaching HTL in such way as further this type of fault never occur in output?".
Here inline quality controlling inspector watch carefully all reasons such as" why wrong size HTL lable attach with some garment pieces","what are the basic reasons of such kind of faults?". How these faults can control ?.
"Root cause analysis" is key for performing further improvement actions for decreasing the chances of " attaching wrong size HTL lable with knitwear garments pieces. With brainstorming and internal logic of feeling and thinking the inline quality inspector write down all possibilities of errors on a plane paper and soon transfer these figures and dashes line in to a logical map for controlling the attaching of wrong size with some quantity of knitt fabric garments.
The lines quality controlling inspector write all possibilities of wrong size attaching and pasting of HTL on back neck of knitwear garments pieces such as,
There are mix HTL size lable from manufacture sides. May be,there are some percentage chances and these chances are " when packing the paper pieces in to cartons there then mix some numbers of HTL" so inline quality inspector count again these labels while inserting entire focus of attention on the size of lable as per piece,and if there are no errors found then this correct as" there is no mixing of wrong size from HTL producer side.
Inline quality inspector will count the quantity of garment pieces in a moving basket or a bundle depending on whether basket or bundle semi stitch knitt fabrc garments mix with each others basket or bundle because probability and possibility percentage increase at this error point and correlation curve coincide with logical map so inline quality inspector segregate the garment pieces sizewise for controlling the" wrong attachment of HTL on the back neck of garment. Yes inline quality inspector recheck all back flow bundles and baskets for the mixation of garments parts accordance with size specification sheet and if shortcomings found there,then he or she must suddenly inform to inline quality supervisor for further actions and reaction. This is known as" corrective actions" because for improving quality of HTL and reducing "wrong size attachment of HTL on knitt fabric garments neck" the inline quality inspector segregated all mix size garment pieces and again aggregate same size garment pieces in same size piece containing bundle or in a basket. So there are minimum chances of attaching wrong size HTL with garment pieces.
Preventive actions are directly relate with corrective actions,as in above actions plans, for preventing in future such type of wrong attachment of HTL, a large distance and long tables are arrange for stopping the mixing of garment pieces, yes these are known as " preventive actions" because preventive actions stop the occurrence of faults and defects permanently for future easiness and improving quality standard inline of stitching flow.
In this example some one new learner can best understand the methodology of "Corrective action+ preventive action", although this example is very easy and simple for understanding the whole process of quality controlling procedure in inline stitching flow.
If needle hole appear on some operations of the garment during sewing stage on stitching machines and inline quality inspector during inspection found such faults. She or he at once stops the stitching machine operation and ask to machine operator" change machine needle" because needle point is out of order and needle age is over to perform well and properly on fabric for stitching the relevant stitching and sewing operation. And then stitching machine operator change the damage needle as bring new needle from replacing damage needle booth and change machine needle for preventing such type of faults in near future then this action is call as corrective action and for preventive actions the age limit of needle age correlate with this corrective action time period, yes this become standard for replacing needles for stitching machines. And in this way there will be no outcome of faults such as needles hole or needle cuts.
