Fabric coating agent, ultrathin windproof and moisture permeable ultraviolet resistant fabric and preparation method thereof

Abstract

The invention discloses a fabric coating agent, which comprises the following components by mass percentage: 80-90% of water-based amino acid modified polyurethane coating glue, 5-10% of an organic solvent, 1-2% of nano-zinc oxide powder, 1-2% of nano-titanium dioxide powder, 1-2% of nano-jade powder and 2-4% of micropore lignocellulose. The ultrathin windproof and moisture permeable ultraviolet resistant fabric provided by the invention has an anti-ultraviolet protection coefficient UPF of greater than or equal to 50, ultraviolet transmittance UVA of smaller than or equal to 5%, air permeability of less than 10mm / s, water vapor permeability of greater than or equal to 6000g / m<2>.d, and surface moisture resistance of greater than or equal to level 3 after 5 times of washing and drying, and the anti-ultraviolet performance does not decline. The coated fabric has a style closer to natural original cloth.

Description

Technical field [0001] The invention relates to the post-finishing field of textile fabrics, in particular to an ultra-thin fabric anti-ultraviolet coating processing technology, and further relates to a fabric coating agent, a wind-proof, moisture-permeable anti-ultraviolet fabric and a preparation method thereof. Background technique [0002] At present, due to the acceleration of industrialization, global carbon dioxide emissions have increased sharply, the ozone layer in the atmosphere has become thinner, the intensity of ultraviolet rays reaching the ground has increased year by year, and the prevalence of skin cancer has greatly increased; based on this, the development of a functional and practical coexistence The anti-ultraviolet functional coating is particularly important. The existing anti-ultraviolet coatings are mostly used in the processing of tents, curtains, and umbrellas. Generally, in order to achieve a better anti-ultraviolet effect, the fabric requires a large...

AI Technical Summary

Problems solved by technology

The existing anti-ultraviolet coatings are mostly used in the processing of tents, curtains, and umbrellas. Usually, in order to achieve better anti-ultraviolet effect, it is required that the fabric has a large amount of slurry, a thick coating, and better coverage to block ultraviolet radiation. Although the fabric has good anti-ultraviolet performance, the hand feel of the fabric is more obvious; in addition, the ultra-thin skin-clothing finishing fabrics that have recently appeared on the market, although they achieve ultra-thin and windproof effects, they do not have indicators such as anti-ultraviolet and moisture permeability. Can not play a good role in protection

[0003] Many experts or teams at home and abroad have done research on UV coatings, such as patent CN1332290, patent CN1552974 and patent CN103046340A, respectively, from the processing of fabric washing-resistant UV-resistant coatings, fabric antibacterial UV-resistant coatings, and waterproof UV-resistant coatings. The anti-ultraviolet coating has been researched in three aspects. Although the fabric is endowed with new functions on the basis of anti-ultraviolet, it still cannot achieve the effect of multi-functional coexistence such as ultra-thinness, wind resistance, and moisture permeability; Wang Yueping of Beijing Institute of Fashion Technology The associate professor published an article titled Ultra-thin Fabric Anti-UV Finishing Research, which only made a reasonable research on the anti-UV formula of ultra-thin fabrics, and did not introduce other properties of the fabric except anti-UV. The development of anti-UV function of fabrics is still in the preliminary stage
