(3) Very complete basic knowledge of fabrics worth learning – classification of fabrics
1. Classify according to different organizing methods
(1) Woven fabric: a fabric made of two systems of yarns arranged perpendicularly to each other, that is, transverse and longitudinal systems, interlaced according to certain rules on a loom . There are denim, brocade, flat cloth, linen, etc.
(2) Knitted fabrics: fabrics formed by knitting yarn into loops, divided into weft knitting and warp knitting. a. Weft knitted fabrics are made by feeding the weft threads into the working needles of the knitting machine from the weft direction, so that the spun yarns are bent into loops in an orderly manner and threaded around each other. b. Warp knitted fabrics are made by using one or several groups of parallel yarns to form loops on all the working needles of the knitting machine fed in the warp direction at the same time.
(3) Nonwoven fabric: made by bonding or sewing loose fibers. Currently, two methods are mainly used: bonding and puncture. This finishing method can greatly simplify the process, reduce costs, improve labor productivity, and has broad development prospects.
2. Classification according to the raw materials of spinning yarns constituting the fabric
(1) Pure fabric: The raw materials that make up the fabric are all made of the same fiber, including cotton fabric, wool fabric, silk fabric, polyester fabric, etc.
(2) Blended chemical fiber fabric: The raw materials constituting the fabric are made of two or more different types of fibers, which are blended into chemical fiber fabrics to form yarns. They include polyester, viscose, Polyester, polyester-cotton and other blended chemical fiber fabrics.
(3) Mixed fabric: The raw material of the fabric is made of single yarns of two types of fibers, which are combined to form strands. There are low-elastic polyester filaments and medium-length blended yarns. In addition, there are also polyester staple fibers and low-elastic polyester filaments mixed into strands.
(4) Interlaced fabric: The raw materials constituting the two-directional system of the fabric are made of different fiber yarns, including ancient satin interlaced with silk and rayon, and nylon and rayon interlaced nylon. Spinning etc.
3. Classification according to whether the raw materials constituting the fabric are colored
(1), white fabric: a fabric made from unbleached and dyed raw materials, also known as silk weaving Raw fabrics.
(2) Colored fabrics: Fabrics made from bleached and dyed raw materials or fancy threads. Silk fabrics are also called cooked fabrics.
4. Novel fabric classification
(1). Bonded cloth: It is made of two pieces of fabric bonded back to back. Bonded fabrics include organic fabrics, knitted fabrics, non-woven fabrics, vinyl plastic films, etc. They can also be combined in different ways.
(2). Flocking finishing fabric: The fabric is covered with short and dense fiber fluff, which has a velvet style and can be used as clothing and decorative materials.
(3) Foam laminated fabric: Foam plastic is adhered to a woven or knitted fabric as the base fabric, and is mostly used as cold-proof clothing.�
(4) PU coated fabric: The base fabric of woven fabric or knitted fabric is coated with PVC (PVC), neoprene, etc., and has excellent water-blocking function.
