Many years ago, when I just graduated from college, I worked in the sales of professional clothing. In the niche field of sports clothing, a kind of fabric with moisture-wicking function was popular. Now in the decoration furniture panel industry, I got to know a kind of fabric. PET-finished European pine board, minimalist home decoration style is very popular now. It turns out that the two materials are made from the same raw material – polyester fiber.
As an edible fiber, it can solve the problems of moisture absorption, perspiration, and quick drying. It is one of the most important demands of wearers and is also a topic that relevant companies and researchers have focused on for many years. Clothing material.
It must have started around 2009. This time, clothing made of polyester fiber materials was very popular in professional basketball, badminton and other sports events and niche circles. At that time, I remember, a piece like this A set of T-shirts and shorts cost 200 yuan. This was more than 10 years ago.
Compared with cotton fabric clothing, when the wearer is engaged in high-intensity sports activities or productive labor, it is better to wear physical or / Hygroscopic-perspiration-quick-drying functional clothing based on chemically modified polyester. Sweat can quickly moisten such fabrics, and the sweat can rely on the yarns and singles that make up the fiber assembly on the surface and inside of the fabric. Capillary diffusion formed between fibers.
As the diffusion area increases, sweat can quickly evaporate to the surrounding environment, that is, while moistening, diffusing, and evaporating, there will be no uncomfortable feeling of clothing sticking to the body. This is The fibers constituting the moisture-absorbing-perspiration-quick-drying functional fabric are required to have reasonable chemical and physical structures. [1]
We sweat a lot when we exercise outdoors. If the fabric has poor moisture absorption and perspiration properties, it will cause a sense of sticking and stuffiness. Therefore, outdoor sportswear fabrics should have better moisture absorption and perspiration properties. Performance, it can quickly absorb and transfer sweat after it is produced, keeping you comfortable and dry.
Moisture wicking mainly uses grooves or capillary phenomena on the fiber surface to transfer sweat to the fabric surface and evaporate quickly.
Based on GB/T 21655.1-2008 “Evaluation of moisture absorption and quick-drying properties of textiles – Part 1: Single combination test method” to measure water absorption, drip diffusion time and water evaporation rate; refer to FZ/T
0107-2008 “Test Method for Capillary Effect of Textiles” to test the wicking height; According to GB/T 12704.1-2009 “Test Method for Moisture Permeability of Textile Fabrics No. 1
Section: Moisture Absorption Method” to obtain the moisture permeability of the fabric. [2]
The surface tension of fibers, the shape and direction of the pores between fibers, and the tightness of fiber aggregates are all major factors that affect the moisture absorption and perspiration performance of fabrics. [3]
At present, the fiber raw materials for outdoor sportswear include polyester, nylon and viscose fiber, etc. [4]. The various requirements for outdoor sportswear fabrics generally require fiber compounding, fabric interweaving or functional To achieve this through finishing [5], for example, PET polyester fiber clothing fabrics have very good moisture absorption and perspiration properties. They are very cool and comfortable when worn on the body.
With the changes in consumer demands, outdoor sports fabrics with a single function can no longer meet people’s needs, and existing multi-functional outdoor sports clothing fabrics have more or less shortcomings. The development and application of new fibers, the continuous development of spinning technology, the accelerated replacement of polymer composite materials, the continuous improvement of weaving processes, and the development of new dyes and finishing methods have promoted the direction of outdoor sportswear fabrics towards functional diversification, thinner fabrics, and technological intelligence. It develops in the direction of modernization, natural colors, green production and personalized design.
In response to existing problems, researchers can start from aspects such as the selection of fiber raw materials, the adjustment of weaving processes, the dyeing and finishing processes, and the design of clothing details, and try a variety of new fiber blends to maximize the Improve the wearability and functionality of fabrics.
