What are the characteristics of woven fabric, knitted fabric, knitted fabric and non-woven fabric?

Woven fabric: Due to the development of filament texturing technology, various synthetic filaments can be processed into yarn-like filaments similar to natural fibers through various types of texturing methods, which eliminates the traditional spinning methods of natural fibers, greatly reduces the production cost and opens up a brand-new road for the wide use of filaments. Among them, the textured polyester filament can be woven into a low-elastic wool-like product with good bulkiness and strong wool-like feeling (according to the requirements of wearing comfort, the product should have the elasticity of 12 ~ 18%), so the polyester processed yarn.

Knitted fabric: weave type is an important quality characteristic that determines the extensibility, dispersibility, grammage, thickness and shape stability of knitted fabric. Knitted fabrics are distinguished by a large number of different weaves, and different properties, colors or structural effects can be obtained by using different weaves. It is an important direction for the development of knitting industry to obtain light knitted fabrics without lowering the quality index. By changing the structure of knitted fabric through the combination of different weaves, the square meter weight of fluff knitted fabric produced by single needle bed and double needle bed machine can be reduced. The terry-thickened knitted fabric developed by the teaching and research group of knitting production technology of Tahige Textile Research Institute belongs to this kind of knitted fabric. The structural feature of this knitted fabric is that it consists of terry and pad.

Woven fabric: Non-woven fabric stitched into a series of longitudinal loops on a fiber web or yarn layer by warp knitting principle. It is also possible to weave a certain structure on the base fabric (fiber net or yarn layer) to make a stitched fabric, whose appearance and performance are between woven fabric and knitted fabric. Because of its simple manufacturing process, high output and high economic benefit, there are two kinds of stitched fabrics with fiber mesh, which are widely used in clothing, decoration, industry and other fields: one is to sew fiber mesh with chain knitting, warp knitting or satin to make warp yarns; The other is to extract fiber bundles from the fiber web and sew the fiber web with links. Most or all of the stitched fabrics are made of fiber webs, which can be used as materials for filtration, insulation, decoration, padding, coated base cloth, toys and so on. A stitched fabric is formed by stitching weft layers with warp yarns to form loops. Its appearance is similar to that of woven fabric and its tear strength is higher than that of woven fabric. Mainly used as industrial cloth, such as coated base cloth, inflatable building conveyor belt, etc., and can also be used for clothing or decoration. It is also called needle knitting. There are three main types: ① terry yarns are sewn on the base fabric to form terry, which is made of napping; (2) using two guide bars, wherein the guide needle of one guide bar penetrates into the ground yarn to form a loop reinforcement yarn layer, and the guide needle of the other guide bar penetrates into the wool yarn to form a multi-needle weft insertion structure as a needle back pad, and then the weft insertion rises; (3) Feed the base fabric and fibers into the sewing area, directly extract fiber bundles from the fiber web to form loops, and sew the fiber web and the base fabric together. This kind of fabric is fluffy and can be used as interlining, artificial fur, carpet and blanket.

Nonwovens: The production technology and product structure of nonwovens have its unique characteristics, which makes it develop rapidly and be used more and more widely in recent 20 years. Its technical characteristics mainly include wide application range of raw materials, short process flow, high production efficiency, high output, low cost and wide product uses. In the production process of nonwovens, the raw materials used can range from textile waste flowers, lint, waste silk and plant fibers to organic and inorganic fibers; All kinds of fibers range from 0.00 1d to tens of denier, as short as 5mm and infinitely long. The outstanding characteristics of nonwovens production technology are short process flow and high production efficiency, and its production speed can be increased by 100 ~ 2000 times or even higher than that of traditional textiles. 1 Because of its short production process and high degree of automation, the average production line has as few as 3-4 people and as many as 10 people, and it can produce 1 ton to hundreds of tons of products every day. Therefore, it has the characteristics of high efficiency and low cost. Nonwoven products are widely used, which can be used in clothing, decoration, industry and other fields. Such as suede fashion, sportswear, ski clothes, children's clothing, travel underwear, household carpets, electric blankets, exhibition hall carpets, tablecloths, artificial flowers, curtains, cleaning products, geotextiles, building waterproof materials, medical and health materials, sound insulation materials, thermal insulation materials, agricultural cloth, packaging materials, furniture cloth, filter materials, automobile interiors, industrial protective clothing, bulletproof clothing, etc. Especially in the field of industrial use, nonwovens have their own unique product structure characteristics that traditional textiles can't match. Different from traditional textiles, nonwovens are not interwoven by fiber bunching into yarns, but are formed by fiber orientation or random arrangement in single fiber state, so they can better reflect the characteristics of fibers themselves than woven and knitted fabrics. In the web-forming stage, almost any nonwoven web shows three-dimensional structure, but it shows different geometric structure based on different consolidation methods. Needle punching, hot melting, spray welding, spunlace, melt blowing and other products all have typical three-dimensional structures, while thin mats, hot rolling and other products are mostly embodied in planar network structures, that is, two-dimensional structures. These structural characteristics determine that nonwoven products are small and tortuous in pore size, large in porosity, high in elongation, good in coverage and shielding, fluffy in structure, soft to the touch and good in elasticity, which makes them have greater advantages than traditional textiles in many application fields.
