Problems solved by technology

Clothing fabrics can be woven with acrylic fibers alone, or blended with acrylic fibers and cotton, or acrylic fibers and other chemical fiber fabrics to prepare clothing fabrics. Since acrylic fiber fabrics have more anionic groups, the softener generally contains ammonium groups (NH 4+ ) strong cationic groups, when the acrylic fiber-containing fabric is processed, the anionic groups on the surface of the acrylic yarn will preferentially absorb a large amount of cationic ammonium groups, which will affect the full penetration of the amino silicone oil into the deep layer of the acrylic fiber and reduce the wear and tear of the fabric. Softness, bulk and resilience

Abstract

The invention provides a softener for after-treatment of acrylic-fiber-containing cloth. The softener is suitable for after-treatment of the acrylic-fiber-containing cloth. The softener comprises, byweight part, 1-20 parts of amino silicone oil, 1-15 parts of emulsifier, 0.5-5 parts of glacial acetic acid, 1-25 parts of polyvinyl alcohol, 1-10 parts of octadeyl dimethyl tertiary amine, 2-12 partsof ternary copolymerized silicone oil, 1-25 parts of polyethylene glycol fatty acid ester, 1-10 parts of fatty acid amide, 1-5 parts of a stabilizer, 1-5 parts of a stiffness agent and 40-80 parts ofwater. In the after-treatment process, a product treated by the softener for after-treatment of the acrylic-fiber-containing cloth can be endowed with good bulkiness, softness, elasticity and good stiffness. The invention further provides a preparation method of the softener for after-treatment of the acrylic-fiber-containing cloth.

Description

technical field [0001] The invention relates to the technical field of cloth finishing, in particular to an acrylic-containing fabric softener for finishing and a preparation method thereof. Background technique [0002] With the development of science and technology and the improvement of people's living standards, the requirements for textiles are getting higher and higher. Through the finishing process, fabrics can be endowed with color effects and shape effects (smooth, suede, resilience, bulkiness, softness, Stiffness, etc.) and effective (impermeable, non-felting, non-ironing, non-moth, flame-resistant, etc.) technical treatment methods. Fabric finishing is to improve the appearance and feel of fabrics and improve wearability through chemical or physical methods. The technical process of performance or endowing special functions is the "icing on the cake" processing process of textiles. [0003] Traditional clothing fabrics use cotton and wool to make clothing. If the...
