In the current fierce competition in the apparel fabrics market, functional products have become a major highlight of companies' adjustment of product structure and transformation and upgrading. Various types of functional products emerge in an endless stream. At the upcoming Autumn 2016 Winter and Autumn Yarn Show in October, a wide range of new functional yarn products will be unveiled to showcase the elegance of yarn as a source of industry.
Smart temperature control fiber
Wearing air conditioners on the body has been achieved by fiber companies. This "smart" fiber, called warm fiber, combines the characteristics of textile materials with the introduction of specialized knowledge in physics and chemistry, cross-discipline, and cross-border innovation. The success and wide application of materials have improved the quality of life of the general public and indirectly saved energy consumption in automatic thermostats. They are environmentally friendly materials and are adaptable to current development trends. According to different adjustment mechanisms, warm fiber can be divided into medium phase change temperature control fiber, medium dissolution temperature control fiber, thermoregulation fiber and temperature control fiber.
Studies have shown that when the human body is in thermal equilibrium, the average temperature of the skin that feels comfortable is about 33.4°C, and the difference between the skin temperature of any part of the body and the average skin temperature is in the range of 1.5°C to 3.0°C, and the body feels neither cold nor hot, exceeding ± In the 4.5°C range, the human body will feel warm and cold. Thermostatic fiber is a bidirectional thermoregulator. It has an endothermic function when the ambient temperature is high and an exothermic function when the ambient temperature is low. The original function of the fiber is fundamentally expanded and it is a new type of “smart†fiber.
Differentiated spandex fibers
Differentiated fibers refer to chemical fibers that are different from common conventional properties, that is, chemical or physical means are used to change the structure, morphology, and other characteristics of a chemical fiber, so that it has a chemical fiber with one or more special functions. The best-selling Functional Spandex fiber products include: Matte Spandex, Easy Spandex, Diaper Spandex, and Black Spandex. Ultra-fine denier products are characterized by ultra-thin and comfortable products. The characteristics of black spandex are not white, long-term color fastness, can solve the problem of low color fastness and color fastness of the fabric. Diaper Spandex, leaving tail silk, can increase production efficiency for customers and reduce production costs. These products adapt to the functional requirements of the processing of garment fabrics, with distinct characteristics and pertinence, such as: high temperature resistance, chlorine resistance, easy dyeing, high resilience, low temperature and easy adhesion.
Environmentally-friendly functional staple fibers and high-performance fibers
The environmentally-friendly functional staple fibers mainly exhibited at this exhibition include:
1) Cool white products - with good whiteness, a certain degree of anti-ultraviolet effect, safety and environmental protection (additives through the US FDA certification), has formed a series of products such as fabrics, non-wovens and sewing threads to meet the needs of different end users .
2) Color yarn - excellent color fastness, good spinnability, product safety and environmental protection. At the same time, in order to meet the user's demand for the strength of colored silk products, through the technology upgrade, the production of high-strength (black) colored silk products has also been achieved, and the strength can be increased by 20% to reach the intensity level of the original white product.
3) Ultra-high strength - using a special process, product strength up to 7.0cN/dtex, suitable for the production of high-strength and wear-resistant fabrics.
4) Antimicrobial staple fiber - Using a safe and reliable antibacterial agent, the product is cost-effective and can effectively inhibit bacteria, mold and other microorganisms from multiplying on the surface of the fiber, and the antibacterial rate can reach 99.9%.
5) Environmental Health and Health Spurs - Product characteristics are environmental protection and health. Accumulation of heavy metals in the human body will exceed the limits to which the human body can tolerate. It will cause harm to human body poisoning. The content of heavy metal cesium in conventional products is about 4ppm, although it meets the requirements of eco-textiles. However, the value of lanthanum is higher, while the environment-friendly spunlace staple fiber does not contain lanthanum. Therefore, the content of heavy metals in the fiber is almost impossible to detect, which is more conducive to human health.
High-performance fibers are chemical fibers that have specific physicochemical structures, properties and uses, or have special functions, and generally refer to fibers having a strength of more than 17.6 cN/dtex and an elastic modulus of 440 cN/dtex or more. High-performance fiber products have excellent mechanical properties and weather resistance, and are mainly used in military defense and marine engineering. The high-performance fibers of Yizheng Chemical Fiber have the characteristics of softness and good spinnability.
Cool feel nylon and antibacterial nylon
Cooling fiber utilizes extraction and nanotechnology, and natural natural jade powder, shell powder, mica powder and other natural mineral materials are selected and processed into nano-sized particles, which are then processed by spinning with hydrophilic chips and passed through fiber cross-sections. The design allows the fiber to have a "wicking effect" and increase the speed of heat dissipation. After the fabric made of this fiber contacts the skin, it will produce an instant cooling effect that lowers the body surface temperature by 1° C. to 2° C. The prolonged exposure to sunlight will produce a temperature difference of 5° C. to 6° C. which lowers the body surface temperature. Cool polyester staple fiber, cool polyester filament, cool nylon 6 stretch yarn, cool nylon 6 high orientation silk are the main representatives.
In order to better promote health, people are still developing antibacterial fibers for human safety, and are currently quite popular internationally. They are silver-based antimicrobial fibers such as silver-based antimicrobial nylon, silver-based antimicrobial polyester, and silver-based antimicrobial polypropylene. Antibacterial fibers can be widely used in home textiles, underwear, sweatshirts, etc., especially for the elderly, pregnant women and infants and young children. Clothes made of this kind of fiber have good antibacterial properties and can resist the attachment of bacteria on the clothes, thereby keeping people from invading the bacteria. The antibacterial fiber's resistance and killing effect to bacteria is not a one-time temporary effect, but a long-term efficacy of several weeks to several years. This long-term antibacterial property is due to its built-in design, which enables the antimicrobial agent to slowly elute, forming a zone of inhibition on the surface of the fiber. Even if the surface antibacterial agent is washed away, new antibacterial agents will overflow. Form a new inhibition zone. Therefore, clothes made of this fiber have good washability. At present, many research institutions around the world are developing new types of antimicrobial fibers.
