Problems solved by technology

[0003] The post-finishing of fabrics is generally done with silicone oil emulsion. If it is treated with amino silicone oil, although it has a certain degree of bulkiness and softness, it does not have a heavy feeling, lacks elasticity, and does not have a smooth feel, so it cannot be used as a high-grade fabric.
In particular, the commonly used amino-modified silicone oil has strong cationicity, and its emulsified emulsion cannot be used in the same bath with anionic finishing agents such as coatings, brighteners, and residual soaping agents (such as horse-polypropylene copolymers). , when the above-mentioned functions are required, they can only be processed individually, which makes the fabric finishing process various and reduces work efficiency

Abstract

The invention provides super-smooth silky silicone oil for fabric after-treatment. The oil comprises comprises, in parts by weight, 2-20 parts of ethoxylated stearamide, 4 to 30 parts of hydroxyl silicone oil, 2 to 20 parts of amino polyether silicone oil, 1 to 15 parts of carboxyl modified silicone oil, 1 to 15 parts of polyurethane modified silicone oil, 5 to 15 parts of alcohol ether carboxylate, 0.1 to 5 parts of non-ionic emulsifier, 1 to 10 parts of glacial acetic acid, 0.1 to 5 parts of glycerol and 40 to 80 parts of water. The treated product is good in smoothness, strong in moisteningfeeling, full and saturated, and has a silk-like feeling, so that the grade of the product is greatly improved, and the economic benefit is greatly increased. The oil can be used in a same bath withanionic substance finishing agents such as a coating, a brightening agent and a soaping agent, so that conventional multifunctional finishing split-bath use is changed into the one-bath use, the multifunctional finishing of the fabric becomes easy, the energy loss is reduced, and the treatment efficiency is improved. The invention further provides an after-finishing process.

Description

technical field [0001] The invention relates to the technical field of fabric finishing, in particular to a super-smooth and silky silicone oil for fabric finishing and a finishing process. 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, shape effects (smooth, suede, silk, crisp, etc.) and real effects. (impermeable, soft, elastic, non-felting, non-ironing, non-moth, flame-resistant, etc.), fabric finishing is to improve the appearance and feel of fabrics, improve wearability or endow special functions through chemical or physical methods The technological process is the "icing on the cake" processing process of textiles. [0003] The post-finishing of fabrics is generally done with silicone oil emulsion. If it is treated with amino silicone oil, although it has a...
