(5) Very complete basic knowledge of fabrics worth learning – classification of knitted fabrics
Knitted fabrics are mainly divided into two categories: weft knitted fabrics and warp knitted fabrics. Weft-knitted fabrics are used in sweaters, socks, etc. Warp-knitted fabrics are often used as underwear fabrics. Hand-knitted fabrics are also weft-knitted.
In weft knitting, the yarn is reciprocated laterally (or circularly) from one side of the machine to the other, and a new knitting needle can be formed by combining the knitting needles. Knitted fabric loops. The yarns of weft knitted fabrics are spun in the transverse direction, and the fabric is formed by knitting needles in the course direction to knit rows of rows of loops that are connected up and down. All loops in a row are knitted from one spun yarn. Weft knitted fabrics can be made on a flat knitting machine or a circular knitting machine.
Warp knitting is a group of warp yarns in the warp direction that are relaxed longitudinally, and the knitting needles are relaxed to form new knitted fabric loops. Warp knitted fabrics and the warp knitting machines that produce them are essentially different from weft knitted fabrics and the weft knitting machines that produce weft knitted fabrics. Spun yarns are woven in the warp direction in warp knitted fabrics, just like the warp yarns of woven fabrics. The yarns are supplied by the warp beam, and a large number of parallel arranged spinning yarns are wound on the warp beam, similar to the warp beams in weaving. . The direction of the spun yarns in warp knitted fabrics is warp direction. Form a vertical loop in one row, then move diagonally to the other row and form another loop in the next row. The yarns move along the length of the fabric in a zigzag pattern from side to side, and each loop in a row is made from a different yarn.
Weft knitted fabrics account for the largest proportion of knitted fabrics.
Weft knitted fabrics mainly include basic weft knitted fabrics (plain knitted fabrics are also called weft plain, rib fabrics, double-reverse knitted fabrics), very Weft knitted fabrics (bib knitted fabrics, double-sided knitted fabrics, plush, knitted terry fabrics, knitted velvet, etc.)
Warp knitted fabrics mainly include warp plain and warp knitted fabrics. Differences between velvet and velveteen
