Description
Technical Field
The invention relates to the technical field of textile fabrics, in particular to a light-absorbing and heating sports fabric, a preparation method thereof and a product.
Background
Fabric is the material used to make clothing. As one of the three elements of the clothes, the fabric not only can explain the style and the characteristics of the clothes, but also directly controls the expression effects of the color and the shape of the clothes. The functional fabric refers to a fabric with certain special performance and purposes, such as water resistance, wind resistance, air permeability, moisture permeability, heat preservation, oil resistance, easy decontamination, bacteria resistance, deodorization, ultraviolet resistance, static resistance, radiation resistance, flame resistance, high temperature resistance, acid and alkali resistance and the like. The functional fabric in the market is mainly made of garment fabric and is mainly used for outdoor sportswear and high-grade casual clothes. Among the new functional textile materials, polyester fiber is the most developed synthetic fiber.
Warmth retention is one of the most important properties of winter clothing. The novel warm-keeping clothes usually adopt warm-keeping fibers capable of actively heating as raw materials, namely the warm-keeping effect on a human body is achieved by means of self heating of the warm-keeping fibers, and common products comprise moisture absorption heating fibers, light absorption heating fibers, phase change heating fibers and the like. The light absorption heating fiber is a warm-keeping material which can absorb visible light and infrared rays in solar radiation and can reflect heat radiation of a human body. Under the condition of a proper light source, the fiber product can absorb the heat generated by the high-energy wavelength band light wave in the light and absorb the heat radiated by the light source, thereby achieving the effect of keeping warm. The heat-insulating effect of the product can be evaluated by testing the light absorption and heat generation performance of the product. The light absorption and heat emission performance refers to the performance that textile converts, absorbs and stores light energy and heat energy under the illumination condition, so that the energy in the material is gathered and the temperature is increased.
Nylon is a term for polyamide fiber (chinlon), and can be made into long fiber or short fiber. Nylon is a trade name for polyamide fiber, also known as Nylon (Nylon). The basic component of Polyamide (abbreviated as PA) is aliphatic Polyamide linked by amide bonds [ NHCO ] -.

2. the mechanical property is poor, or the fabric is not well compatible with the performances such as moisture absorption and sweat releasing effects, wearing comfort level and the like (the compatibility is not good), and when the fabric is used as the fabric of outdoor (sports) clothes, the fabric is easy to damage and has short practical life; or poor performance such as moisture absorption and sweat releasing effects and uncomfortable wearing.
