Step 1 ⚫ Yarn inspection is the first essential quality control procedure at a sweater factory before knitting production starts. After raw yarn is delivered from suppliers, quality inspectors check all yarn cones thoroughly to confirm the yarn complies with the customer’s order requirements and knitting production standards.
Step 2 ⚫ Winding is a crucial pre-knitting process in sweater manufacturing. Delivered yarn usually comes on large bulky cones, hanks or loose skeins, which cannot be directly loaded onto computerized knitting machines. During winding, workers use winding machines to rewind the original yarn onto small, neat, standard bobbins. Meanwhile, the machine automatically removes defects such as yarn knots, thick/thin slubs, broken threads, dirt and oil spots on the yarn.
Step 3 ⚫ Tech design is the full technical planning and pattern drafting work before a sweater is officially knitted. Based on customers’ sample pictures, sketches or size specifications, technicians draw detailed technical documents for production.
Step 4 ⚫ Jacquard design focuses specially on creating multi-colour woven patterns on sweaters. Designers layout graphic motifs, colour matching and colour arrangement for jacquard knit fabrics, then convert the artwork into digital programmes compatible with computer flat knitting machines.
Step 5 ⚫ Panel knitting is the core knitting procedure in traditional sweater production, meaning knitting each separate garment component (called a panel) individually on computer flat knitting machines according to technical patterns and size standards.
Step 6 ⚫ Linking is the key stitching process to assemble all separately knitted sweater panels into one whole garment, which is a unique sewing method for knitwear.
Step 7 ⚫ Link off refers to binding off / casting off stitches on a single piece of knitted fabric. No two fabric pieces are joined here. When knitting finishes on the edge of one panel (neck edge, cuff opening, bottom hem), workers lock all loose yarn loops permanently to stop stitches from unraveling, fraying or curling up. It seals the raw edge of knitwear neatly, ensuring smooth, comfortable borders that will not come loose after wearing and washing.
Step 8 ⚫ Washing－This is professional garment washing, not ordinary home laundry. Finished sweaters are put into special washing machines filled with water and mild detergents, softeners or finishing agents. Drying－Right after washing, damp sweaters go through controlled drying processes.
Step 9 ⚫ Ironing, also commonly called blocking in knitwear industry, is a vital finishing step after washing and drying sweaters. Workers use steam irons, steam pressing tables or professional sweater steam boards to shape and smooth finished knit garments under controlled steam and gentle pressure.
Step 10⚫ Garment inspection is the final comprehensive quality check carried out on fully finished sweaters before packing and shipment to customers. It takes place after ironing and shaping, and is the last quality control checkpoint in the whole knitwear production flow.
