Problems solved by technology

The first ones used in the finishing of wool and cashmere garments contain only non-crosslinked or non-crosslinkable linear organopolysiloxanes. Although they have good smoothness, the softness, especially the fluffy feeling, is not satisfactory.

[0047] Component A consists of silicone oil (E), (F), (J):

[0048] Silicone Oil (E)

[0049] Silicone Oil (F)

[0050]

[0051] The structural formula of adding component B is

[0052]

[0053] The high dimethicone polydimethylsiloxane (G);

[0054] The structural formula of adding C component is

[0055] Silicone Oil (H)

[0056] ;\

[0057] Or add D component general formula (CH 3 )Si(OCH 3 ) 3 the oligomer (K),

[0058] The above-mentioned siloxanes are combined with surfactants BASF company T05, T07 is emulsified into an emulsion with a concentration of 30% by weight, and then diluted to 1%. After processing wool and cashmere garments, 5 people are used to blindly evaluate the hand feeling and anti-felt shrinkage, and measure the longitudinal and transverse shrinkage after washing. Washing conditions: bath ratio 1:50, temperature 40 ℃, time 15 minutes, weak alkaline or neutral detergent...

Embodiment 11-16

[0062] Among them, in component A,

[0063] In silicone oil (E), m=200, n=8;

[0064] In silicone oil (F), m=2800, n=5;

[0065] In silicone oil (J), m=1000, n=0;

[0066] In component B silicone oil (G), p=5500;

[0067] In component C silicone oil (H), q=0, t=35;

[0068] According to the same method of embodiment 1-10, its composition formula and use effect are as shown in table 2:

[0069] Table 2, embodiment 11-16 formula and use effect

[0070]

[0071] From Table 1 and Table 2, it can be concluded that the softening and smoothing agent of the present invention has better hand feeling and better anti-felt shrinkage compared with the existing amino-modified silicone oil smoothing agent.

Abstract

The invention aims to provide a softening-smoothing agent for the after-finishing of wool / cashmere garments. Special amino silicone oil and linear polysiloxane which is non-crosslinked or can not be crosslinked are compounded and then mixed with a silane or siloxane matter which can be crosslinked to form the softening-smoothing agent which is stable to store and is used for finishing the wool / cashmere garments, so as to obtain better softness, fluffy sense and smoothness degree, obviously reduce felting trend or shrinkage. Therefore, the wool / cashmere garments can be washed by a machine.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a softening and smoothing agent for processing wool and cashmere garments. Background technique [0002] Wool and cashmere garments are finished before commercialization to obtain a soft and smooth finish. The products used for this purpose are initially treated with oils and fats such as wax emulsions, fatty acid polyamides, polyamide quaternary ammonium salts, and alkyl quaternary ammonium salts. Although a certain soft and fluffy hand can be obtained, it has no slippery feeling and is not resistant. wash. It has also been treated with acrylic and polyurethane polymers. Although satisfactory anti-felting effect can be obtained, the hand feel is obviously deteriorated, making it difficult to obtain approval. [0003] The emergence of silicone has brought a leap in the finishing of wool and cashmere garments. The first used in the finishing of wool and cashmere garments is l...
