Abstract

The invention discloses a hydrophilic softening finishing agent for a cotton fabric and a preparation method of the hydrophilic softening finishing agent. The hydrophilic softening finishing agent isprepared from, by weight, 53.5-58.5% of octamethyl cyclotetrasiloxane, 1.35-1.5% of tetramethyl dihydro disiloxane, 1.35-1.5% of concentrated sulphuric acid, 2.7-3% of sodium carbonate, 10-15% of allyl polyethylene glycol bisepoxypropyl, 17-26% of isopropanol, 0-0.12% of an isopropanol solution of chloroplatinic acid with the mass fraction of 1%, 2.5-3% of tetramethylenediamine and 1.5-2% of glacial acetic acid. The hydrophilic softening finishing agent prepared by adopting the formula and the method is more easily emulsified, after being subjected to hand feeling finishing, the cotton fabriccan be endowed with the good hydrophilic performance, in addition, the fabric has a soft style and low yellowing performance, and the use requirement is met.

Description

technical field [0001] The invention relates to the technology in the field of textiles, in particular to a hydrophilic softening agent for cotton fabrics and a preparation method thereof. Background technique [0002] Softening finishing refers to the fact that textiles are subjected to moisture heat treatment with various chemical agents and subjected to mechanical tension during the dyeing and finishing process. Defects Processes that make fabrics soft to the touch. [0003] At present, the softening agents used in softening finishing are generally not easy to emulsify. After finishing the cotton fabric, it cannot give the fabric good hydrophilic properties, soft style, high yellowing, and cannot meet the needs of use. Therefore, it is necessary to study a scheme to solve the above problems. Contents of the invention [0004] In view of this, the present invention aims at the deficiencies of the prior art, and its main purpose is to provide a hydrophilic softening age...
