Problems solved by technology

However, in this method, the masking agent coated on the outer layer of the fabric will fall off as the number of washings increases or the time of use increases, resulting in a decline in the UV protection effect and even environmental pollution.
In addition, some organic masking agents have certain toxicity and are not suitable for prolonged contact with human skin
For example, Chinese patent CN 103469555 B discloses a preparation method of a textile fabric using graphene as a shielding agent. Although it has a considerable UV protection effect, this fabric still has an UV protection effect with the increase in the number of washings and the wear of the fabric surface. recession risk
This type of UV protective fabrics on the market will have a very limited service life due to washing and wear, which not only reduces the cost performance of the product, but also causes waste of resources and environmental pollution due to the elimination of expired products

Abstract

The invention relates to a graphene / nylon 6 textile with a permanent ultraviolet protection property and a preparation method thereof, and belongs to the field of functional textiles. The graphene / nylon 6 textile with the ultraviolet protection property is obtained by making a graphene / nylon 6 composite fiber into a textile; the graphene / nylon 6 composite fiber is obtained by the in-situ polymerization of modified graphene and caprolactam and carrying out melt spinning. The graphene / nylon 6 textile obtained by the preparation method not only has excellent physical and mechanical properties, but also has functions, particularly the ultraviolet protection property, that multiple nylon 6 textiles do not have; further, the functions of the graphene / nylon 6 textile are permanently effective, and cannot be attenuated due to the increment of the water scrubbing times of the textile. The ultraviolet protection factor (UPF) of the graphene / nylon 6 textile is more than 40; the ultraviolet light transmissivity (T) (UVA (Ultraviolet A)) is less than 5 percent; the graphene / nylon 6 textile meets the requirements, about anti-ultraviolet products, of a standard GB / T18830-2009, and can serve as an anti-ultraviolet functional textile to be used for the fields of skin coats, parasols, curtains and the like.

Description

technical field [0001] The invention relates to a graphene / nylon 6 fabric with permanent ultraviolet protection performance and a preparation method thereof, belonging to the technical field of functional fabrics. Background technique [0002] Nylon 6 (also known as nylon 6) fabric has excellent properties such as high strength, wear resistance, good resilience, moth resistance, and corrosion resistance. It is widely used in various clothing materials, masking materials and knitwear. Nylon 6 fabric is a light fabric, very suitable for high-end mountaineering clothing, winter clothing, etc. [0003] Ultraviolet light usually refers to the general term for radiation with a wavelength of 10-400nm in the spectrum. Sunlight contains a lot of ultraviolet radiation, of which the UVB (280-320nm) part that can reach the surface has higher energy, which can cause strong photodamage to human skin, causing dermal blood vessels to dilate, redness, swelling, blisters and other symptoms. ...
