Embodiment 1

[0012] The preparation of embodiment 1 cationic polymer emulsion

[0013] Nitrogen gas was passed into the four-necked flask equipped with a stirring device, a condenser tube and a nitrogen gas feeding device for 5 minutes, and then a certain amount of deionized water and 1.2% by mass of cationic emulsifier cetyl trimethyl chloride were added. Ammonium, stirring continuously (speed about 300r / min), so that the emulsifier is evenly distributed in the water, and then add 1 / 3 of the mixed purified monomer (mixture of styrene and butyl acrylate), of which styrene and acrylic acid Butyl esters were pre-emulsified for about 30 minutes according to the weight percentage of 7:13, 8:12, 9:11, 10:10, and 11:9; after the emulsification, the reaction temperature was slowly raised from room temperature to about 80±1°C (heating The time is about 1h, and the heating rate is about 1°C / min); after reaching 80°C, use a constant pressure dropping funnel to drop the remaining 2 / 3 of the mixed mon...

Embodiment 2

[0014] Example 2 Application of cationic polymer microspheres in paint dyeing

[0015] The pre-treated cotton knitted fabric was washed and dried according to the bath ratio of 1:50, and the cationic polymer treatment solution was prepared at 0.5%, 1%, 1.5% and 2% of the weight of the fabric respectively, and the fabric was placed in the treatment solution at 50°C Shake for 30 minutes, then wash twice with water at a bath ratio of 1:50, each time for 5 minutes; prepare a dye solution of RED HH-B with a bath ratio of 1:25 and 2% of the weight of the fabric, and wash the treated The fabric is immersed in it and dyed at 50°C for 30 minutes, then taken out, washed three times, pre-baked at 80°C for 3 minutes and then baked at 120°C for 5 minutes, and the dyeing is completed.

Embodiment 3

[0016] Example 3 Application of cationic polymer microspheres in paint dyeing

[0017] The pre-treated cotton knitted fabric was washed and dried according to the bath ratio of 1:50, and the cationic polymer treatment liquid was prepared at 2% of the weight of the fabric. Wash twice with water at a bath ratio of 5 minutes each time; use a bath ratio of 1:25 to formulate a coating RED HH-B dyeing solution at 0.5%, 1%, 1.5%, and 2% of the weight of the fabric, and treat the treated The fabric is immersed in it and dyed at 50°C for 30 minutes, then taken out, washed three times, pre-baked at 80°C for 3 minutes and then baked at 120°C for 5 minutes, and the dyeing is completed.

Abstract

The invention discloses a cationic polymer emulsion for dip dyeing of a coating. The polymer emulsion is synthesized by adopting an emulsion polymerization method by taking styrene and butyl acrylate as a monomer, hexadecyltrimethyl ammonium chloride as a cationic emulsifier and azobis methylpropion amidine dihydrochloride as a cationic initiator. Emulsion particles in the polymer emulsion have positive charges and can be combined with coating particles and fibers with negative charges, so that the emulsion particles can be fixedly attached on the surfaces of the fibers. According to the cationic polymer emulsion applied to dip dyeing of the coating, the color depth, the fastness and the hand feel are improved.

Description

technical field [0001] The invention discloses a cationic polymer emulsion for paint dipping, which belongs to the field of textile printing and dyeing, and in particular relates to a preparation method and application of a cationic polymer emulsion for paint dipping. Background technique [0002] Paint dyeing is one of the anhydrous and water-less dyeing and finishing technologies advocated for many years. It has many advantages such as simple production process, low production cost, strong variety adaptability, energy saving, less wastewater discharge, and ecological environmental protection. However, since the paint itself has no affinity with fibers, a large amount of adhesive needs to be added when dyeing medium and dark colors, resulting in poor hand feeling, obvious decline in rubbing fastness and washing fastness, and difficulties in dyeing medium and dark colors. [0003] In patent CN 101289601 B, under the addition of cross-linking monomer 1,3-butanediol dimethacry...
