Description
Technical Field
The invention belongs to the technical field of novel spinning, and particularly relates to a China-hemp uvioresistant blended yarn and a production process thereof.
Background
With the continuous development of textile technology in China, the functionality of the fabric is gradually improved. In some special fields, the use of traditional fabrics is greatly limited. The new functions of the fabric are generally improved by adopting the following method: the surface of the fabric is treated by methods such as spraying, dipping and coating, or modified by a chemical modification method, or an auxiliary agent is added into the spinning solution to endow the fabric with new performance.
For human body, proper amount of ultraviolet radiation has bactericidal effect and can promote the synthesis of vitamin D, which is beneficial to human health. However, under the continuous irradiation of burning sun, the skin of human body loses the resistance, burns easily occur, and erythema or blisters appear. Excessive UV radiation can also induce skin diseases (such as dermatitis and xeroderma pigmentosum), even skin cancer, promote cataract formation and reduce immune function of human body.
In optical principle, ultraviolet radiation is irradiated onto the fabric, part is reflected at the surface, part is absorbed by the fabric, and the rest is transmitted through the fabric. In general, the transmittance + reflectance + absorptance of ultraviolet rays is 100%. Therefore, the transmittance of ultraviolet rays can be reduced by increasing the absorptivity and reflectance of the fabric to ultraviolet rays. At present, most of the existing anti-ultraviolet radiation fabrics are made by adding a sun-proof film layer on the fabric, or the fabric is improved to be light and thin, wherein the sun-proof film layer on the fabric endows the fabric with certain ultraviolet reflectivity and absorption rate, but the fabric is poor in air permeability, particularly hot and stuffy in summer, after long-time cleaning, the anti-ultraviolet performance can be gradually weakened until the fabric disappears, and the improvement on the light and thin fabric can only reduce the ultraviolet transmittance, so that the sun-proof effect is not good.
In view of the above, the research on an anti-uv blended yarn and a production process thereof has become a technical problem to be solved by those skilled in the art.
