Synthesis method for anti-napping and anti-pilling conditioning agent for fabric

Abstract

The invention discloses a method for synthesizing an anti-pilling finishing agent for fabrics; it mainly includes the following steps: (1) using a silane coupling agent and octamethylcyclotetrasiloxane as raw materials, using a strong acid as a catalyst, and removing In the presence of ionic water liquid, react within the temperature range of 50°C to 85°C to prepare an anionic silicone emulsion; (2) add an emulsifier to the emulsion prepared in step (1), and use an oxidation-reduction system initiator , and acrylate hard monomers, acrylate soft monomers, and cross-linking monomers composed of at least one of methacrylic acid and acrylic acid, carry out copolymerization reactions with cross-linking agents, and the reaction temperature is 55 ℃~80℃, the organic silicon-modified acrylate emulsion with interpenetrating network structure is obtained; after finishing the fabric with the finishing agent prepared by the method of the present invention, the anti-pilling performance of the fabric can reach 3-4 grades, at the same time, it has almost no effect on the original feel and style of the fabric.

Description

technical field [0001] The invention relates to a method for synthesizing an anti-pilling finishing agent for fabrics. Background technique [0002] Cashmere and wool fibers enjoy the reputation of "fiber gems" for their soft, light, soft, slippery and waxy properties. At the same time, the cashmere products made by it have the unique style of comfortable wearing, strong warmth retention, full suede, soft hand feeling, soft luster and smooth wax, which are favored by consumers. In the actual wearing and washing process of cashmere sweaters and wool sweaters, due to continuous friction, the fibers on the surface of the fabric are exposed on the surface of the fabric, and the surface of the fabric is fluffy. This phenomenon is called "fluffing". If these hairs cannot be shed in time during continuous wearing, they will be entangled with each other and rubbed into many spherical particles, which are usually called "pilling". These hair balls protruding on the surface of the f...

Problems solved by technology

[0003] At present, addition and subtraction are generally used for anti-pilling finishing. Subtraction is like ethanolamine sulfite, but it will cause great damage to the fiber when finishing the fabric, thereby reducing the strength of the fiber; addition is like water-soluble heat-reactive polyurethane resin. , Acrylic resin; Resin is a variety of polymers, using the function of the resin to form a film on the surface of the fiber, so that the surface of the fiber is wrapped with a layer of wear-resistant resin film, which reduces the directional friction effect of the cashmere fiber , so that the slippage of the fiber is weakened; at the same time, the resin is evenly cross-linked and condensed on the surface of the yarn, so that the fiber end adheres to the yarn, and it is not easy to pill when rubbing, so it can effectively improve the pilling resistance of the cashmere sweater ; But its disadvantage is that it is easy to make cashmere or wool lose its original style and feel hard
