Problems solved by technology

The strength of the fabric after the non-ironing finishing agent of polycarboxylic acid is high, and the hand feeling is poor, and the non-ironing effect is not ideal
The fabrics finished with polyurethane anti-wrinkle and non-ironing finishing agent have good anti-wrinkle effect and good hand feeling. The disadvantage of polyurethane anti-wrinkle and non-ironing finishing agent is that the production conditions are harsh and the price is expensive. Questioned the nature of the isocyanate group and clearly stipulated the residual amount of the isocyanate group on the textile, which limits the application of polyurethane in the textile

Abstract

The invention relates to a preparation method of a non-ironing finishing agent of a modified self-crosslinking organosilicon anti-wrinkle microemulsion. At present, the non-ironing finishing agent with good performance does not exist. The preparation method comprises a process of preparing amino-modified silicone crude oil and a process of preparing an emulsion finishing agent; the process of preparing the amino-modified silicone crude oil comprises the steps of: mixing amino-modified silicone oil and a solvent, dripping epoxy chloropropane, heating the mixed liquor to a temperature of 40-60DEG C, preserving the temperature to react for 2-4h, and cooling to a temperature of 15-25DEG C to obtain the amino-modified silicone crude oil, wherein the proportion of the amino-modified silicone oil to the solvent to the epoxy chloropropane by weight is 1: (1-1.5): 0.09252X, and X is 0.3-0.9; and the process of preparing the emulsion finishing agent comprises the steps of: preparing the following materials in percentage by weight: 8-15% of fatty alcohol-polyoxyethylene ether, 0.2-0.3% of glacial acetic acid, 54.7-73.8% of water and 18-30% of amino-modified silicone crude oil, adding the fatty alcohol-polyoxyethylene ether in the modified amino-modified silicone crude oil to emulsify, and adding the glacial acetic acid and the water to obtain the product. The preparation method of the non-ironing finishing agent of the modified self-crosslinking organosilicon anti-wrinkle microemulsion is simple in process, easy for preparation and reliable in product performance.

Description

technical field [0001] The invention relates to a preparation method of a modified self-crosslinking silicone anti-wrinkle microemulsion non-ironing finishing agent. The modified self-crosslinking silicone anti-wrinkle microemulsion non-ironing finishing agent is mainly used for anti-wrinkle of cellulose fabrics and blended fabrics Easy-care finishing. Background technique [0002] In 1926, the first anti-wrinkle finishing patent applied by the British TBL company clearly stated that the two initial shrinkage bodies of phenolic formaldehyde and urea-formaldehyde should be condensed into resin inside the cellulose fiber, which may be the origin of the original name of anti-wrinkle finishing as resin finishing. Due to the color change of phenolic initial shrinkage after finishing, its popularization and application is limited (only for dark colors) and gradually eliminated. [0003] In 1955, some new anti-wrinkle finishing agents with better performance appeared on the market...
