Knitting is a weaving process for fabrics commonly used in clothing. At present, most of the fabrics in our country are knitted and woven. Knitted fabrics are formed by forming loops of yarn or filaments with knitting needles, and then interlocking the loops. A woven fabric is a fabric formed by interweaving warp and weft yarns perpendicular to each other.
According to different process characteristics, knitting is divided into two categories: weft knitting and warp knitting. Knitted fabrics are fluffy, soft, smooth, less hairy, have good wrinkle resistance and air permeability, and have greater extensibility and elasticity. They are comfortable to wear and are mostly used to make close-fitting clothing. When it comes to inspection, the inspection points for knitted garments are also slightly different:
Key Points for Inspection of Knitwear
Compare the product with the customer's confirmation sample, reference sample, craft sheet, color sample or picture, etc., to judge whether the style and sewing process are correct.
