Wash-wear nonwoven fabric capable of selectively blocking ultraviolet rays

Abstract

The invention discloses a wash-wear nonwoven fabric capable of selectively blocking ultraviolet rays, and belongs to the field of a functional textile, and particularly relates to a nonwoven fabric with an ultraviolet-proof function. The nonwoven fabric is prepared through the following steps: by adopting a large piece of graphene oxide as ultraviolet absorption padding, uniformly mixing the graphene oxide and water-based polymer resin in water to obtain a mixture, coating two sides of the nonwoven fabric with the mixture, and drying and molding the nonwoven fabric. The average transmittance of the nonwoven fabric in the long-wavelength ultraviolet area is less than 4 percent, and the ultraviolet-proof factor is more than 30, the transmittance of the nonwoven fabric in a visible light area is reduced by 30 to 50 percent compared with that of the pure nonwoven fabric, and the performance still can be maintained after the nonwoven fabric is severely stirred in water for 30 days. The wash-wear nonwoven fabric is simple, low in cost, environmentally friendly, suitable for industrialized mass production, high in selectivity, good in ultraviolet-proof performance, wash-wearable and good in flexibility, and a coating has small possibility of falling off, and can resist acid and alkali. The wash-wear nonwoven fabric can preserve the heat and can be used in fields such as ultraviolet protection clothing, ultraviolet protection screen windows and ultraviolet protection paulin.

Description

technical field

[0001] The invention relates to the field of functional textiles, in particular to a non-woven fabric with an ultraviolet-proof function. Background technique

[0002] As we all know, sunlight contains visible light, infrared rays and ultraviolet rays, among which ultraviolet rays are electromagnetic waves with shorter wavelengths than visible rays. People usually call short-wave or very short-wave ultraviolet rays with a wavelength below 290nm, namely UVC; those with a wavelength of 290-320nm are called medium-wave or far-wave ultraviolet rays, namely UVB; those with a wavelength of 320-400nm are called long-wave or near-wave ultraviolet rays, namely UVA . On the one hand, ultraviolet rays can promote the synthesis of vitamins in the human body, prevent rickets, and have beneficial effects such as sterilization and health care. The skin loses its elasticity, increases wrinkles, and even causes cancer. Among them, ultraviolet rays with lower wavelengths ar...
