Its polyester filaments include POY, DTY, FDY, ITY, composite wire, medium strong silk 6 series, more than 1,000 varieties, including Poy, FDY, DTY three series products selected for national green design products. Its 5 special series of products include green source, Shuofi, bombs, colorful silk and Kang Yi.

Sun Yanlin focused on the process route and research and development of hot and humidity functional fibers. According to reports, in 2017, Tongkun Group participated in the national key R & D plan project issued by the Ministry of Science and Technology, with this, with this opportunity, 5 textile specialty colleges, such as Donghua University, and Ruyi Group, Jia Linjie, Sunshine The group and other well-known enterprises work together to develop multi-point online to add melt braided production of functional hot wet wires.

Hot and humidity functional fibers select a suitable comonomer, break through the controlled polymerization technique of moistureter polyester, and improve the water purification of the polyester material. This design is designed to high-standard cross-sectional spool plate and function masterbatch addition technology, optimize the humidification, moisture and cool, moisturizing heat-free fiber spinning technology.

Sun Yanlin introduced: "After a small trial, the product of the successful product is verified and serialized, changing the content of coolness and warm sensing, as well as fiber section design, and optimizes the sewer design, and advances engineering. "

The test products of the series of fibers include: cold sensing fiber (jade powder), three types of circular holes, cross, caterpillar; and warm fibers (coffee carbon), three kinds of round holes, hollow, caterpillar Spinheral hole. Among them, the core technology of the moisture and cool fiber is a good ventilation moisture absorbing structure, and the cooling fiber prepared high stability; the core technology of moisture absorption and heat fibers is to prevent the body from escaping, and after heat absorption Infrared light.

According to reports, the function of functional pellets will have an impact on product wobbleability and performance indicators. From the viewpoint of tie performance index from cool fibers, in the cooling effect of cool fibers, when the amount of the masterbatch is 5% (the effective content of jade powder is 1%), the fiber can show a better cool sensation. effect. At the same time, the fiber gasification moisture effect of cross section is best.

In terms of moisture absorption, the coffee carbon is blended with PET, the twin screw is moltered, and the tensile strip, and the particles are obtained. The POY cross section of the heating fibers is relatively regular, and the hollow fiber section is very obvious. Adopt hollow section, which is beneficial to keep the air inside to achieve warmth effect. The warm sensing series is in the test process, as the mass particle proportion increases, its spinning assembly is significantly decreased, and the elongation is gradually growing, and the spinning process is more severe than the cooling fiber. When the amount of coffee carbon pellets is less than 7%, the POY breakage intensity has not changed significantly; when the amount of addition is 9%, the POY breakage intensity is significantly reduced. The thermal effect of hollow cross-section fibers is preferably, hollow cross-section is basically disappeared, but still has a significant fluffy. The far infrared emissivity of the fiber reached 0.89, and the far-infrared radiation temperature increased by 2.1 ° C.

How to engineered it? Sun Yanlin said: "The ultimate goal is to develop melt-splicing products, reaching product precision design, quality precision control, cost accurate control, customer precision docking. Due to the large melt brake scale, intelligent manufacturing is functional polyester The development of the chemical fiber industry is inevitable. "
