Uvioresistant spun yarn, fabric, and modification equipment and modification method of fabric

Abstract

The invention discloses an anti-ultraviolet fabric, which achieves the anti-ultraviolet purpose while maintaining the texture and performance of the original fabric. According to the technical scheme, the uvioresistant spun yarn is characterized in that the uvioresistant spun yarn is prepared by mixing titanium dioxide and zinc oxide into composite fibers for modification treatment, the composite fibers are prepared from 90.6% of chinlon master batches and 9.4% of spandex master batches through melt spinning, a modifier is added into the spun yarn for modification treatment, and the modified spun yarn is prepared by blending the titanium dioxide and the zinc oxide into the composite fibers. The modifier comprises the following components in percentage by mass: 94.9% of polyamide, 1.8% of titanium dioxide, 1.8% of zinc oxide, 0.5% of silicon-based oxide, 0.5% of aluminum oxide and 0.5% of magnesium oxide; the invention further discloses modification treatment equipment for the anti-ultraviolet fabric, and the modification treatment equipment is used for carrying out modification treatment on a common fabric to obtain the anti-ultraviolet fabric. On the basis of the modification treatment equipment, the invention provides the modification treatment method of the anti-ultraviolet fabric, and the original fabric is subjected to modification treatment through the method to obtain the anti-ultraviolet fabric.

Description

Technical field [0001] The present invention relates to the technical field of fabric production, specifically a kind of anti-ultraviolet spinning, modification equipment and modification methods for fabrics and fabrics. Background [0002] In addition to the comfort, warmth, breathability and other aspects of clothing, protective fabrics are also gradually valued by people engaged in all aspects of work, especially for long-term outdoor work groups, beauty-loving women and groups in low-latitude areas, whether clothing or protective clothing fabrics have sufficient ultraviolet resistance has become the appeal of such people. [0003] Ultraviolet rays can be classified according to different wavelengths: long-wave ultraviolet UVA (320~400nm), medium-wave ultraviolet UVB (280~320nm) and short-wave ultraviolet UVC ( <280nm). Among them, UVC can be absorbed by the ozone layer 25km away from the ground when passing through the atmosphere, and will not reach the ground; most of th...

Problems solved by technology

Among them, when UVC passes through the atmosphere, it can be absorbed by the ozone layer 25km away from the ground and will not reach the ground; most of UVB is absorbed by the dermis of the skin, which promotes the denaturation of nucleic acids or proteins in skin cells, and long-term radiation will cause erythema and skin aging. In severe cases, it can cause skin cancer; although the energy of UVA is low, its penetration to clothing and skin is deeper than that of UVB, which can cause the deposition of melanin and make the skin dark. Long-term accumulation can still lead to skin aging

[0004] The current anti-ultraviolet fabric is generally attached to the surface with a coating with anti-ultraviolet properties, but the coating made by the existing process is less stable and easy to fall off, and its performance is often greatly weakened after several washings. In addition, since the coating is directly applied to the surface of the fabric, the fabric loses its original texture and also affects the performance of the fabric itself (such as air permeability), and the coated surface is more reflective than the fabric itself, which may be harmful to the wearer or discomfort caused by others
