“In the next five years, the T-3000 product is expected to reach an annual output of 200,000 tons. For new products, it takes an arduous process from successful development to mature application. Fortunately, we have already gone a long way.” ——Cheng Min, executive deputy general manager of Jiangsu Xinbo Polymer Materials Co., Ltd. (hereinafter referred to as “Jiangsu Xinbo”), is very optimistic about the market prospects of the company’s new product high elastic fiber T-3000, which is “the first in China and the world’s leading”. .
Indeed, elastic fabrics are deeply loved by consumers for their unique comfort and flexibility, and their application fields are gradually expanding, from traditional socks, underwear, and sportswear to casual wear, high-elastic fashion, automobile decoration, medical use, etc. field.
Jiangsu Xinbo uses petroleum and natural gas products as raw materials. Starting from the invention of the molecular structure of fiber, it adopts the world’s first unique process and equipment to produce T-3000 with long-lasting, stable and high elasticity, becoming a “leader” in the stretch fabric market. A dark horse”.
Perhaps everyone is not too unfamiliar with T-400. It overcomes the shortcomings of classic elastic fiber spandex in terms of high temperature resistance, alkali resistance, and chlorine resistance; it solves the problems of traditional elastic spandex filaments that are difficult to dye, have excess elasticity, and are complex to manufacture. The fabric has many problems such as unstable size and easy aging during use; it can also be woven directly on air-jet, water-jet, and arrow looms. It does not have to be made into covered yarn before being woven like spandex. In this way, T400 Elastane further reduces production costs and improves product quality uniformity. So what is the unique excellence of T-3000 that opens a new era in the elastic fabric market? Let’s take a look together.
Low cost and high performance
T-3000 solves the problem of T-400 high-elastic fiber having a hard feel. With its excellent performance and high cost performance, it is widely used in knitted, warp knitted, woven and other textile fabrics. It can be purely spun into swimwear, yoga clothes, sports and leisure fabrics, knitted stretch denim, etc. It can also be blended with natural fibers such as cotton and wool and chemical fibers such as polyester and nylon to make denim, jacquard fabrics, etc.
It avoids the shortcomings of spandex that is easy to age, does not color, is not resistant to chlorine bleaching, and is easy to curl. The breaking strength of T-3000 fiber is high, and the textile fabrics made are not easy to wrinkle, resistant to chlorine bleaching, and easy to dye. Compared with spandex covered yarn, its cloth surface is smooth, non-blistering, and does not expose the core. It has excellent anti-pilling and fluffing properties, and its friction resistance level reaches level 4-5.
More importantly, compared with spandex and T-400, the raw material cost of T-3000 high-elastic fiber is lower and the supply is sufficient. This makes the sales price of T-3000 high-elastic fiber of various specifications generally higher than that of spandex. High elastic fiber prices are low.
Wearers told us that T-shirts made of T-3000 have unique luster, good cotton feel, soft and full feel, comfortable, smooth and cool human touch, and good elasticity…
Flexible applicability
T-3000 fiber has flexible applicability. In terms of spinning, elastic fibers can be obtained by direct melt spinning, or new elastic fibers can be obtained by spinning elastomer melt and polyester melt.
The siphon effect between fiber and fabric gives the fabric good moisture absorption and discharge effect. T-3000’s unique special-shaped cross-section makes it highly absorbent. Let’s use data to illustrate: T-3000 double-sided knitted fabric has a water absorption rate of 114.8% and a wicking height of 18cm/30min. The water absorption rate of T-3000 single-jersey knitted fabric reaches 161.6%, and the wicking height is 14cm/30min. It can be seen that the fabric directly made from T-3000 has good moisture absorption, perspiration and breathability properties, and can keep the skin dry and comfortable.
In addition to good moisture absorption and dehumidification effects, it also has good elasticity. After testing by the National Professional Product Quality Supervision and Inspection Center, the longitudinal and transverse stretch elastic recovery rates of T-3000 filament fabric are both about 80%. Without adding spandex yarn, the fabric has good elastic recovery effect, and the elasticity is long-lasting and stable. . Let’s look at a set of data: yarn breaking strength ≥2.4cN/dtex, yarn breaking elongation 22±5%, and crimp shrinkage 40±4%. Knitted fabric elasticity: transverse elasticity reaches more than 120%, longitudinal elasticity reaches more than 80%; fiber curl elasticity reaches as high as 97-100%.
“Stability” is the most critical
Process innovation and breakthroughs are the basis of product advantages. By adopting unique esterification technology and making breakthroughs in the fields of materials and chemical engineering technology, the alcohol/acid molar ratio of the raw materials used in the polymerization process of T-3000 was greatly reduced, and a small amount of by-products generated during the production process were treated with in-depth treatment. Recycling technology solves environmental pollution and responds to the requirements of national environmental protection policies.
Cheng Min said: “In terms of equipment selection, we have cooperated with first-class domestic companies to innovate in polymerization, spinning equipment and other aspects. The T-3000 spinning raw material is not a single one. When two raw materials flow at the same time, the flow rate There are differences, which require relatively high accuracy of equipment. We have also tried a variety of equipment and through continuous improvement, we have chosen the best equipment company to cooperate.
After a series of technological processes and finally winding and shaping, the elastic fiber produced can directly meet the use of subsequent weaving. Reduces the production process of textile products and facilitates downstream weavingManufacturer’s application. The efficient catalyst shortens the esterification time and significantly improves the production efficiency. It shortens the polymerization time and significantly improves the production efficiency. By using a one-step high-speed spinning method to prepare fibers, the spinning speed is high, the production efficiency is high, the equipment investment is reduced, and the production cost of the fiber is further reduced. We still speak with data: During the dyeing process, the bath ratio of T-3000 high elastic fiber fabric can be as low as 1:15, and the heat setting temperature is usually 155℃~160℃, which is 30~ lower than the setting temperature of general polyester and nylon. 40℃, thus reducing energy consumption by a quarter, saving resources for the country, and also a manifestation of social responsibility.
Have confidence in T-3000
On the one hand, the concept of “no elastic, no fabric” has penetrated deeply into the fabric market. With the improvement of living standards, consumers are paying more and more attention to the comfort of clothing. Driven by consumer demand for elastic fabrics and recognized by consumers, T-3000 is not just a 200,000-ton product.
On the other hand, I purchased weaving, dyeing and finishing equipment myself to make sample fabrics. Through continuous exploration and innovation, I mastered the complete set of T3000 weaving, dyeing and finishing technology. In terms of production, we hire high-end international talents to fully achieve the stability of technology, production and quality.
Cheng Min is not only optimistic about the future elastic fabric market, but also has full confidence in the wide application of T-3000.
