Problems solved by technology

[0005] The existing waterproof finishing agent is made of fluorine-containing boric acid derivatives as the main raw material. The commonly used two-dipping and two-rolling production technology is used to finish the waterproof finishing agent on textiles through coordination and complexation. The resulting textiles Not only has good waterproof performance, but also does not affect its inherent wash fastness and whiteness, but the softness and elasticity of the fabric finished with this finishing agent are poor, and when folded, the surface is prone to creases

Abstract

The invention discloses a waterproof finishing agent and a preparation method and application method thereof. the waterproof finishing agent is prepared from, by weight, 45-55 parts of an acrylate copolymer, 2.5-3.5 parts of an acrylamide / ammonium acrylate copolymer, 1.8-2.2 parts of formaldehyde and 45-55 parts of water. The waterproof finishing agent can make the surface elasticity of a waterproof curtain for a bathroom good and soft, and has the advantages of being good in waterproof performance, low in breathability and moisture permeability, and excellent in antibacterial performance.

Description

technical field [0001] The invention relates to the technical field of textile auxiliaries, more specifically, it relates to a waterproof finishing agent and its preparation method and application method. Background technique [0002] Waterproof curtains for bathrooms are curtain-like items that are hung outside the bathtub with shower head or in the shower range. Waterproof curtains are mainly used to prevent rainwater splashes from splashing outside the shower, and to shield people in the shower. When the temperature is low, the waterproof curtain also has the function of gathering hot steam and maintaining the local temperature in the shower area. [0003] Traditional bathroom waterproof curtains are made of materials such as plastic or cloth. Cloth-type waterproof curtains are made by waterproofing fabrics. There are three main methods of waterproofing fabrics, water-repellent finishing, coating finishing and lamination. finishing method. Among them, the water-repellen...
