A fashion fabric for long-lasting light storage and luminescence for night running and its preparation process

Abstract

The invention discloses a lasting light storing and emitting fashion fabric worn during evening running and a preparation process thereof. The fashion fabric comprises an inner layer and an outer layer, wherein the inner layer is a reflective layer made from triangular special section polyester full-brilliant fibers; the outer layer is formed by knitting polyester draw texturing yarns; the inner layer and the outer are interwoven together by tucking to form a bilayer structure. The fashion fabric has the beneficial effects that the fashion fabric not only has the light storing and reflecting functions but also is designed in such a manner that the emitted light can be reflected by the fabric and be stored to be reused, so that the fashion fabric has lasting and stable light storing and emitting functions; the fabric not only is light and thin but also has elasticity and moisture absorbing and quick drying properties; the light storing and emitting functions of the fabric are excellent and lasting and light emitting patterns can be designed randomly, so the fabric meets the requirements of the age.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a fashion fabric for night running with long-lasting light storage and luminescence and a preparation process thereof. Background technique [0002] With the improvement of living standards, people are becoming more and more aware of health. Running is undoubtedly an aerobic exercise that people are keen on and has become a part of life. It is mainly limited by the accelerated pace of life and the intensification of social competition. Due to the restriction of production and work, most working-class people have less and less time to exercise, leading to the rise of various marathon long-distance running and various forms of outdoor night running activities, which enrich the spiritual life of the public and exercise their bodies. Night running is becoming more and more popular. A trend becomes a habit. [0003] In the dark environment of night running, it is more an...

Problems solved by technology

[0003] In the dark environment of night running, it is more and more necessary to wear a high-visibility and fashionable sportswear. The principle of the currently visible light-storing and luminous fabric is to add light-storing and luminescent materials to polyester, nylon or polypropylene resin. Fluorescent fibers are prepared by blending and spinning, and then luminescent fabrics are formed by weaving. However, due to the small diameter of the spun fibers (about 20µm), the fluorescent fibers have specific requirements for the particle size of the luminescent materials (larger particle It is easy to block the fiber during the silk process; the particle size is too small to store light and the luminous brightness is low), which limits its development to a large extent

The reflective material uses the "cat's eye" principle, and the light falling on it is reflected back to the light source. The reflective clothing also uses a similar principle. It is equipped with a coating containing tiny glass or resin balls, which can reflect light back to the place like a mirror. Light source, but reflective textiles only have reflective function and can only emit light when there is an external light source; for example, the reflective products produced by 3M Company can reach extremely high brightness after being irradiated by strong light, but they do not have the ability to be used in dark places. Reflective effect, the use environment is limited

Another way to make the fabric have high visibility is to embed light-emitting diodes, but the cost and process of this method are complicated, and it must have a continuous power supply, which greatly affects the wearing comfort of the fabric.
