Classification And Performance Of Fibers

Botany fibre Cotton and linen. Animal fibers: silk and wool. Artificial fiber (regeneration): viscose, soybean fiber, glass fiber, metal fiber. Synthetic fibers: polyester, brocade, nitrile, vitamin, propylene, ammonia, chlorine (nylon). Classification of yarn: pure cotton yarn: combing / semi finishing / combing (high evenness, high strength and easy coloring). Chemical fiber yarn: polyester, nitrile, viscose, and polyvinyl chloride yarn. Blended yarn: T/C, C/C, T/R. Strands: yarns twisted together by more than two yarns. Filament: monofilament and multifilament. Textured yarn: high elastic nylon yarn, low elastic polyester yarn and acrylic bulky yarn. It has higher strength and resilience. Firm and durable, no ironing, easy to wash and fast drying. But moisture absorption is poor, wearing a stuffy heat, easy to generate static electricity and dust pollution. It is resistant to acid, alkali and light resistance. It is not afraid of mold or moth. It uses different kinds of fibers to identify different kinds of fibers. But only for pure textiles and interwoven products. Fancy yarn: slub yarn, small spiral flower, bubble yarn and magic yarn are not suitable for blended new products, core spun yarn products and products after fire proofing.

Classify the raw materials according to the yarn. Pure textile The warp and weft yarns of fabrics are made up of single raw materials. Such as cotton fabric, linen, silk fabric, wool fabric made of natural fibers. It also includes purified fiber fabrics made of chemical fibers, such as synthetic cotton, polyester silk, acrylic fiber and so on. The main feature is the basic performance of the fiber. The blended fabric is blended with two or more than two chemical components of the same or chemical composition to form a fabric. The main feature of the blended fabric is to embody the superior properties of all kinds of fibers in the raw material so as to improve the wearability of the fabric and expand its applicability. Varieties are: linen / cotton, wool / cotton, wool / linen / silk, wool / polyester, polyester / cotton and so on. The naming principle is: the blending ratio is larger, the blending ratio is smaller, the blending ratio is the same, the natural fiber is in front, the synthetic fiber is in the rear, and the artificial fiber is at the end. Interwoven fabric, warp and weft yarn raw materials, or warp and weft yarn in a group of filament yarn, a group of short fiber yarn, interwoven fabric. The basic properties of interwoven fabrics are determined by different kinds of yarns, generally with different warp and weft directions. Its varieties are silk and wool interwoven, silk and cotton interweave.

Classify according to the method of forming fabric. Woven fabrics It refers to fabrics made of shuttle or shuttleless looms with warp and weft yarn. The main feature is that the cloth is divided into meridional and zonal directions. When the fabric is warp and weft, the fabric is anisotropic when the raw material, yarn density and density are different. Because of its excellent elasticity, it is also known as elastic fiber. Ordinary products do not use 100% of polyurethane, and the proportion of 5%--30% mixed in fabric. The appearance, moisture absorption and air permeability are similar to natural fibers such as cotton, wool, silk and hemp. They are suitable for making tights. Knitted fabric, a fabric made of one or a set of yarns and formed by a weft knitting machine or warp knitting machine. According to the processing method, it can also be divided into one side weft knitted fabric and double weft knitted fabric. Nonwoven fabric refers to textiles directly formed by fiber bonding, fusion or other methods without the traditional spinning and weaving process.
