The fabric is easy to tear. What is the reason?

1. It is related to the breaking strength and strength of warp and weft yarns
It is related to the fiber material and blending ratio of the yarn, the fineness of the fiber itself (count or count) and yarn fineness (count or count), yarn evenness, moisture regain or moisture content, single yarn or ply yarn, twist of single yarn and ply yarn (twist coefficient), storage life of fiber or yarn and other factors. There are also elastic fibers, including their elongation and other factors will cause large differences.
2. Related to the weaving method and conditions of the fabric
It is related to the density of knitted and woven fabrics, organizational structures (such as plain, twill, satin, jacquard, etc.), and warp and weft yarns.
The warp strength and weft strength are different, and the bursting strength is also different. Whether there is a selvage, a solid edge or a burr, whether to avoid defects and wrinkles, the distance from the edge of the original fabric may be different (so the sampling must be at least 150 mm away from the edge).
In addition, the strength of sizing grey cloth and desizing cloth, dyed and finishing cloth, especially dipped and special finishing cloth, will vary greatly. Weaving technology, dyeing, sanding and so on have an impact. Coarse yarn shows better strength than thin yarn, twill is better than plain weave, and non galling is better than galling. The less corrosive the dyeing is, the better.
3. Related to yarn strength and warp and weft density
In order to improve the strength of yarn dyed fabrics, these two items should be improved. The tensile strength and tearing strength of durable fabric will also decrease after durable finishing, which directly affects the durability of the fabric. The tensile and tear strength of the fabric, the strength and elongation of the yarn, the interweaving resistance and the morphological structure of the fabric before and after the iron free finishing have significant effects on the strength.
When the fabric woven from yarns with high strength and elongation is torn, the stress triangle area is large, and the tearing strength is high when the number of yarns under common stress is large. The weave structure and the density of warp and weft yarns affect the interlacing points and slippage between yarns. With fewer interlacing points, the slippage between yarns is easy, and the tearing strength of the fabric is high.
After a period of wear in the actual wearing process, the yarn in the fabric becomes thinner due to friction, and some parts often suffer sudden tearing.
The following are some parts of the hip of the pants and the parts of the clothing that are hooked by the sharp fabric when squatting. The external force on these parts causes the internal yarn of the fabric to break under the extreme load one by one. During the use of textiles, if they are subjected to local concentrated load for a long time, the strength may reach the limit and decline, thus affecting the tensile and tear strength of fabrics.
Which fabric is resistant to friction?
Nylon cloth
Nylon is developed by Carothers, an outstanding American scientist, and a research team led by Carothers. It is the first synthetic fiber in the world.
The abrasion resistance of nylon cloth ranks first among all kinds of fabrics, 10 times higher than that of cotton and 20 times higher than that of wool. The abrasion resistance of nylon cloth can be greatly improved by adding some polyamide fibers to the blended fabric; When stretching to 3-6%, the elastic recovery rate can reach 100%; It can withstand thousands of times of bending without breaking. It is many times higher than other fiber fabrics of similar products, so its durability is excellent. The clothes made of nylon are suitable for making mountaineering clothes, winter clothes, etc.
oxford 
Oxford cloth, also known as Oxford textile. The traditional combed cotton fabric originated in Britain and named after Oxford University. Oxford cloth began around 1900. The fine combed high count yarn is used as double warp, and the thick weft yarn is interwoven with double weft flat weave.
Soft color, soft cloth, good ventilation, comfortable to wear, easy to wash and dry, mostly used as shirts, sportswear and pajamas. It has the advantages of good waterproof and durability, and is also used to make bags. There are many varieties and patterns of products, including plain color, bleach, color warp and white weft, color warp and color weft, medium light color stripe pattern, etc; It is also made of polyester cotton yarn.
