preparation example Construction

[0052] In a preferred embodiment, the present invention provides a method for preparing a self-emulsifying softener comprising the steps of:

[0053] 1) The siloxane-based monomer, a urethane surfactant monomer, carboxylic monomer, and deionized water added to the kettle, stirring emulsification 1-2h 40-60 ℃;

[0054] 2) heating to 65-85 deg.] C, was added dropwise an aqueous solution of ammonium persulfate to initiate polymerization;

[0055] 3) heating to 80-95 ℃, incubated 1-5h, prepared from the emulsified softener.

[0056] 1) In the above step, with respect to 100 parts by weight of the total siloxane monomer, a urethane surfactant monomer, carboxylic monomer, and deionized water, the siloxane-based monomer is 10- 15 parts by weight, the urethane surfactant monomer is 10-20 parts by weight of the carboxylic acid monomer is 1-5 parts by weight, the siloxane-based monomer is preferably 11-14 parts by weight, preferably, the surfactant is a polyurethane-based monomer is 13-16 p...

Abstract

The invention provides a self-emulsifying softening agent and a preparation method thereof. The self-emulsifying softening agent is composed of a formula (I), a formula (II) and a formula (III). In the formula, m is an integer of 5-40, n is an integer from 1 to 100, R1 is H or CH3, and R2 is COOH or CH2CH(COOH)2. The prepared self-emulsifying softening agent does not contain a solvent and has excellent application stability such as hand feeling, alkali resistance, high temperature resistance and electrolyte resistance, and production is easy to control.

Description

Technical field [0001] The present invention relates to a softening agent and a preparation method, and particularly to a method for preparing an emulsified softener self. Background technique [0002] With the improvement of people's quality of life, the pursuit of textiles more comfort and functionality, the general textile products after a series of chemical, physical and mechanical tension treatment process pre-treatment, dyeing, etc., can cause compaction feel stiffness and other problems, seriously affecting textiles wearability, therefore, often uses hand softener after finishing them, to meet the requirements. [0003] Silicone-based textile softener is a wide application, good performance, the effect of a projecting type softener, since the silicone molecules adsorbed onto the fibers, can greatly reduce the friction between the fibers and the fibers of the fabric softening purposes increased. However, since the conventional silicone emulsion was added in the preparation ...
