Embodiment 1

[0020] A softener for rayon embroidery threads according to the invention, the components and mass percentages are as follows: 20% of quaternary ammonium-based cationic modified aminosiloxane, 5% of ester-based quaternary ammonium salt, nonionic emulsifier secondary alcohol polyoxyethylene Ether (15-S-5:15-S-9=3:7) was 10%, acetic acid was 0.2%, and deionized water was 64.8%. In a variable speed mixer, first add quaternary ammonium cationic modified aminosiloxane and nonionic emulsifier secondary alcohol polyoxyethylene ether and stir evenly, then add ester quaternary ammonium salt and stir, and finally add acetic acid and remove Ionized water, emulsification reaction; stir evenly and distribute.

[0021] Among them, the quaternary ammonium cationic modified aminosiloxane is such as the general formula I, where R 1 is an alkoxy group; R 2 is methyl; R 3 for-C 3 h 6 OCH 2 CH(OH)CH 2 N(CH 3 ) 2 ; 4 For formula II; x=150, y=100, z=90.

Embodiment 2

[0024] A softener for rayon embroidery threads according to the invention, the components and mass percentages are as follows: 10% of quaternary ammonium-based cationic modified aminosiloxane, 1% of ester-based quaternary ammonium salt, nonionic emulsifier secondary alcohol polyoxyethylene Ether (15-S-5:15-S-12=1:1) was 5%, citric acid was 0.1% and deionized water was 83.9%. In the variable speed mixer, first add quaternary ammonium cationic modified aminosiloxane and nonionic emulsifier secondary alcohol polyoxyethylene ether and stir evenly, then add ester quaternary ammonium salt and stir, and finally add citric acid and Deionized water, emulsification reaction; stir evenly and distribute.

[0025] Among them, the quaternary ammonium cationic modified aminosiloxane is such as the general formula I, where R 1 is hydroxyl; R 2 is hydroxyl; R 3 for-C 3 h 6 OCH 2 CH(OH)CH 2 N(CH 2 CH 3 ) 2 ; 4 For formula II; x=105, y=100, z=10.

Embodiment 3

[0027] A softener for rayon embroidery thread according to the invention, the components and mass percentages are as follows: 30% of quaternary ammonium-based cationic modified aminosiloxane, 8% of ester-based quaternary ammonium salt, nonionic emulsifier secondary alcohol polyoxyethylene Ether (15-S-5:15-S-12=2:1) ​​was 15%, glycolic acid was 0.5% and deionized water was 46.5%. In a variable speed mixer, first add quaternary ammonium cationic modified aminosiloxane and nonionic emulsifier secondary alcohol polyoxyethylene ether and stir evenly, then add ester quaternary ammonium salt and stir, and finally slowly add glycolic acid and Deionized water, emulsification reaction; stir evenly and distribute.

[0028] Among them, the quaternary ammonium cationic modified aminosiloxane is such as the general formula I, where R 1 is hydroxyl; R 2 is hydroxyl; R 3 for-C 3 h 6 OCH 2 CH(OH)CH 2 R 4 For formula II; x=360, y=300, z=180.

Abstract

The invention relates to a softening agent for a rayon embroidery thread, which belongs to the field of softening agents for fabrics. The softening agent comprises, by mass, 10 to 30% of modified amino siloxane, 1 to 8% of quaternary ammonium salt, 5 to 15% of a nonionic emulsifier, 0.1 to 0.5% of organic acid and 46.5 to 83.9% of deionized water. A preparation method for the softening agent comprises the following steps: adding the above-mentioned percentages of the modified amino siloxane and the nonionic emulsifier into a variable-speed mixer and carrying out uniform mixing under stirring; then adding the quaternary ammonium salt and carrying out stirring; slowing adding the organic acid and deionized water in proportion and carrying out an emulsification reaction; and then successively carrying out uniform mixing under stirring and split charging. The softening agent for the rayon embroidery thread has good stability, can endow the thread with excellent slippery and reduce static electricity of the thread, lowers a thread breakage rate in the process of high-speed embroidering and improves the luster of the thread.

Description

technical field [0001] The invention relates to a fabric softener, in particular to a softener for rayon embroidery thread. Background technique [0002] Fabric softener has been developed for more than half a century, and has a long history of application on rayon embroidery thread. It has played a significant role in reducing the friction on the surface of the yarn and the thread breakage rate in high-speed embroidery. big effect. [0003] At present, the softener for rayon embroidery thread is generally oily, and it is absorbed to the yarn through the oil tank during the rewinding stage. The variety ranges from the initial white oil to the current low-viscosity simethicone. Since the oiling rate of rayon embroidery thread is controlled at a low oiling rate of 1%, the silicone oil used is low-viscosity dimethyl silicone oil, and oiling through the oil tank will cause uneven oiling. Contents of the invention [0004] The object of the present invention is to provide a s...
