We all know what a sweater is. But do you know – how sweaters are made in factories? Let me explain how sweaters are made through various processes. One more thing I like to share with you that We Jiayan are sweater manufacturers。Let me tell you how our factory works!

Sample development, sample approvals and order receiving process are similar to garment manufacturing. Other processes are explained here in brief.

Yarn sourcing

Yarns are a primary raw material for sweater knitting. Factory sources yarn in hank or spool form. Our factory  had  own spinning mill and yarn dyeing unit.

Winding of yarns

In this process, yarns are winded into cones from hanks in the winding machine. These cones are stored for production.

Yarn issue to production

Yarn distributor is employed for distributing yarn cones to operators. Yarn distributor collects yarns from a yarn store as per the order plan. Yarns cones are given to knitters based on their daily production capacity.

Knitting of sweater panels (Flat knitting)

Knitters knits sweater panels manually on flat knitting machine as per the design provided to them. In piece rate production knitting one worker makes all 4/5 panels (front, back, collar and 2 sleeves panels etc.). The number of a sweater panel may increase depending on style. Like a high fashion, a sweater might have side pockets and belt, front placket. Sweater collar is made in separate knitting machines with same batch/lot of yarns. Flat knitting machines are available in different gauze setting to produce sweaters for different weights. Small components like placket and belts are made in automatic knitting machines.

Checking of panels

Quality checker checks 100% panels on a flat table (or under the light table). Measurement checking of panels is done randomly.

Linking of different sweater panels

Knitted sweater panels are then sent to linking section. Different components of a sweater are joined together by means of linking machine.

Trimming

Loose yarns are trimmed in this stage by the trimmer.

Quality checking of complete sweaters

Sweaters are checked using a light checking machine.

Mending

in this process, knitting defects are repaired manually by the needle. Mending process is done prior to pressing

Button attaching /button holing

Sweaters are available in the front opening as well. So button attaching and buttonholing is done in the finishing stage. A sweater design might have a zipper for the front opening. Zippers are attached. Wash care label and brand label are attached using single needle Lock stitch machine.

Sweater Washing

Washing is the mandatory process for cotton and the acrylic based sweaters. This is also an important process for setting sweater shrinkage. Washing is not recommended for sweaters made of fancier yarns.

Ironing

Sweater stretches easily. Steam irons are used to press the sweater. Measurements are also set in the ironing stage by using templates of different sizes. Measurements and pressing quality are checked after pressing. After the ironing sweaters are kept open to dry the steam.

Folding and Packing

Sweaters are folded. Hang tags, Price Tags and other tags and stickers are attached to folded sweaters and packed into poly bags.

Internal Final audit

This process is not mandatory but few factories audit sweaters prior to handing over shipment to buyer representative for the final inspection.

And we Jiayan must be reviewed

Shipment inspection

Sample-based inspection is carried out by buyers Quality Assurance personnel.

Now after shipment inspection by buyer representative, sweaters are ready for shipping.
