Elastic yarn has high elongation and resilience. When it is fully stretched, it is like ordinary filament yarn; when it is fully relaxed, it is like bulk yarn. The vast majority of elastic yarns are made of thermoplastic filaments. After false twisting and heat setting, the filaments will produce permanent curls, but there is no entanglement between them. Knitted underwear made of them has a tight feeling

Polyester cotton blend spinning: cotton and staple fiber are mixed and spun according to different proportions. Generally, the polyester cotton blended yarn with high polyester ratio is referred to as T/C yarn (T represents polyester, C represents cotton), and the polyester cotton blended yarn with high cotton ratio is referred to as EVE yarn. The common blending ratio of Tie yarn is 65/35 (65% polyester, 35% cotton). The common blending proportion of EVE is 60/40 (60% cotton, 40% polyester), 55/45 (55% cotton, 45% polyester). Other blending proportions can also be determined according to customer needs.

Acrylic fiber is called artificial wool. It has the advantages of softness, bulkiness, easy dyeing, bright color, light resistance, anti-bacterial, and worm resistance. It can be pure spun or blended with natural fibers according to the requirements of different uses. Its textiles are widely used in clothing, decoration, industry and other fields. Polyacrylonitrile fiber can be blended with wool to form wool, or woven into blankets, carpets, etc. It can also be blended with cotton, man-made fibers, and other synthetic fibers to form various clothing materials and indoor articles. The expanded body processed by polyacrylonitrile fiber can be pure spun or blended with viscose fiber.

Staple yarn Product features: short fiber yarn for short. The yarn is spun from short carbon fiber, such as general pitch based carbon fiber, which is usually in the form of short fiber. Main applications: thermal insulation materials, antifriction materials, C/C composite parts, etc.

At first, the appearance of textured yarn was just to increase the bulkiness of fiber by changing the geometric properties of fiber materials, like cotton and fine wool, so that products have plump and warm properties. Through various deformation processes, filament yarn overcomes the shortcomings of filament yarn, has many characteristics of staple yarn (such as expansibility and warmth retention), reduces investment and cost, improves product quality and production efficiency, and expands the use of filament yarn. As early as the 1930s, Smith & Sons carpet company of the United States used stuffing box technology to improve the crimping performance of South American wool. In 1932, heberlein of Switzerland invented the deformation processing method of rayon yarn and obtained the first patent for the crimping deformation of rayon (Applied in 1932 and named nigrila, trade name) In the 1940s, with the industrial production and application of thermoplastic synthetic fibers (nylon and polyester), modified yarns developed rapidly. Because synthetic fiber is thermoplastic, its filament can change the macromolecular arrangement structure in the fiber through "deformation heat setting" under mechanical action, and control the heat setting process to obtain deformed yarn with ideal curling effect. In the 1950s, companies in Switzerland, the United States and Japan used the batch process of twisting, heat setting and untwisting polyamide filaments (classical method). This method can be carried out on any twisting equipment with a "steamer". Disadvantages: many processes, high cost and low productivity. Subsequently, celanise company of Britain proposed two-step deformation and one-step deformation processing method false twist deformation processing method. (false twist texturing), which was produced industrially in the 1950s and gradually replaced the classical three-step deformation processing method. It is characterized by short process, low cost and one-step completion. Polyamide textured yarn produced by Toray in Japan in 1951 by false twist texturing process, trade name: woolie nylon. In 1958, British nylon spinner company developed friction false twister and hoburn company developed the first friction false twister textured yarn machine. In 1959, the British Imperial Chemical Company produced false twist textured yarn (poly (acyl) with high bulkiness and low extensibility by using secondary heat setting (box). DuPont company of the United States pioneered the air modification processing method, mainly processing medium, coarse and special yarns to make decorative fabrics and carpets.

With the withdrawal of Western clothing brands from the Russian market, Russians are increasingly interested in second-hand clothing. Russian "news" reported on the 22nd that since the beginning of this year, more and more Russians have bought clothes, shoes and accessories in second-hand stores. According to statistics, the transaction volume of Moscow credit bank card in such stores increased by more than 2.5 times. Alazarova, a Russian fashion industry expert, said that in the future, second-hand clothing, shoes and other goods will be more popular. Buying clothes in second-hand stores not only saves money, but also conforms to the trend of environmental protection. People feel like "Taobao". Second hand shops are also popular among young people. Volkova, a Moscow citizen, said: "you can buy very high-quality clothes there for very little money." Russian operators have also noticed the booming domestic second-hand commodity market. Russia's ozon e-commerce platform has launched an online classification service for people. Any user can sell or give away their clothes for free on the website.

The high-temperature heat wave swept the world, and the temperature in many places in China broke the historical extreme, and the high temperature lasted for a long time. According to China Weather Network, 68 national stations in China have broken the local historical extreme temperature. The China Meteorological Administration said that as of August 15, the high temperature event had lasted 64 days, the longest since 1961. It is expected that the duration of this regional high-temperature heat wave event will continue to extend and the comprehensive intensity will be further enhanced in the next ten days. In order to meet the basic demand of "ensuring supply", the government has initiated temporary shutdown measures for large power consumers. The affected listed companies in Anhui, Sichuan, Guizhou and other places have issued shutdown announcements one after another, and many companies have announced the shutdown time, as well as the specific affected production capacity and amount.

The high-strength polypropylene twisted yarn has the characteristics of environmental protection, non-toxic, acid and alkali resistance, light specific gravity, small thermal shrinkage, low thermal conductivity, little static storage and almost no moisture absorption. The high-strength polypropylene double twisted yarn has the characteristics of environmental protection and light weight. It is widely used in safety net belt, industrial sling, flexible container bag, geotextile, industrial filter cloth, rope cable, optical cable, high-pressure fire hose, conveyor belt, industrial sewing thread, canopy canvas, polypropylene anti crack fiber, plastic woven bag and other fields. It is a new ideal chemical fiber material to replace polyester, nylon and ethylene fiber, especially suitable for geotextile, sunshade, and other flame retardant / UV resistant industrial products and processes such as Christmas tree
