Problems solved by technology

There are two main reasons (1) When D4 is coupled with the coupling agent aminoalkylsilane to provide the flexibility of the amino group, the reaction is a random copolymerization, and some of the side chains of the polymer silicone chain are connected to the amino group, and there are The amino group is not connected to the amino group. The uneven distribution of the amino group causes the fabric to be soft and viscous alternately after finishing, and the softness decreases.
(2) When D4 is used as raw material, a lot of D3~D7 will be brought into the raw material. Due to the high boiling point, these ring structures cannot be removed after finishing, which affects the hand feeling, softness and anti-pilling and pilling performance
[0005] Water-soluble polyurethane has good washability, such as the patents of Bayer in Germany and Daiichi Kogyo Pharmaceutical Co., Ltd. in Japan. If the amount is too small, it is easy to fluff and pilling, and if the amount is too large, it will feel bad.
[0006] Some softening agents contain non-environmental protection factors, including internationally prohibited substances such as nonylphenol polyvinyl chloride ether for emulsifiers in USP5236465, phthalic acid for cross-linking film enhancers, and dioctyl lauric acid in catalysts. Tin salt, tin dibutyl laurate, tin dibutyl diacetate, tin octoate, etc. are ECO prohibited substances, which will cause environmental pollution
[0007] Patent DE-A2844952 discloses that there is a resin containing mercaptan (mercapto) in the technology, which has good film-forming properties on wool, good washability and hand feeling, but it will release strong-smelling sulfur-containing toxic gases during finishing. , is harmful to environmental protection; Japanese Patent Laid-Open 10-158976 technology uses epoxy resin, which is an internationally banned substance

Embodiment 1

[0042] Materials: warp and weft yarn metric count ≥ 70 S / 2×70 S / 2 and single weft metric count ≥ 35 S / 1, weight≤220g / m 2 Pure wool and blended fabrics. The pre-treatment of pure wool and blended fabrics adopts conventional technology, and the formula of the finishing agent for soft post-treatment is:

[0043] D 100 parts, E 6 parts, G 35 parts, H 2 parts

[0044] I.5 parts, J 3 parts.

[0045] Preparation of D:

[0046] (A) represented by the formula (1) was mixed with γ-diethylenetriaminopropylmethyldimethoxysilane. Under the condition of pH 9, the coupling reaction was carried out at 80°C for 4 hours to obtain (C), wherein, m=47,

[0047] (A): (B)=6:1, weight ratio;

[0048] Add acetic acid to the product (C) to adjust the pH to 6, then add a mixed emulsifier at a temperature of 65°C, stir and emulsify to obtain the compound shown in formula D;

[0049]Said mixed emulsifier is isomeric tridecyl alcohol (EO) 12 and cetyl trimethyl ammonium chloride, and the weight...

Embodiment 2

[0057] Materials: Metric count of warp and weft yarns S / 2×70 S / 2 and single weft metric count S / 1, weight > 220g / m 2 For pure wool and blended fabrics, the pre-treatment adopts conventional technology, and the formula of the finishing agent for soft post-treatment is:

[0058] D 100 parts, E 4 parts, G 25 parts, H 1 part

[0059] I 2.5 parts, J 1 part.

[0060] Others are the same as Example 1, D, E, G, H, I and J are mixed, diluted into the aqueous solution of 30g / l, woolen fabric is dipped and rolled twice at 25 ℃ of temperature, and the liquid rolling rate is 60%, and the speed of a vehicle is 25%. m / min, dry at 125°C, and generate epoxy-siloxane block copolymerized wool fabric softening resin on the fabric, so that the wool fabric has a very significant effect of uniformity, softness and firmness.

[0061] The test results are shown in Table 1. The physical properties are shown in Table 2.

Abstract

The invention discloses a soft finishing agent for wood fabric and the application. The agent in the invention is suitable for softening finishing of wood fabric. Performance indexes of the wood fabric in the invention, such as softness (pure bending, shearing performance, drape coefficient), anti-pilling (pilling index), machine washing performance (total shrinkage and relaxed shrinkage) and so on, are superior to the related standard of international woodmark and nation. The invention is provided with good quality for color even degree in vision, good performance for anti-teasing and anti-pilling, good handle feeling and good softness degree. There is no international forbidden material in it and when finishing there is no poisonous gas with strong odor discharging. It is in favor of environmental protection.

Description

technical field [0001] The invention relates to a wool fabric finishing assistant, in particular to a wool fabric softening and finishing assistant. Background technique [0002] At present, many existing technologies for soft finishing have been formed in the world, such as the technology disclosed in USP5236465. The silicone prepolymer contains benzene rings, which will greatly affect the soft and smooth effect of finishing, and the softness is poor; [0003] Hydrogen-containing silane is a new type of polysiloxane cross-linking agent developed in recent years. It has the advantages of fast reaction speed and good film-forming performance of silicone resin, such as patents DE-A2725714, DE-A2726108, DE-A2903334, DE- A3014675, GBA1436694, GB-A2082215, USP5236465 and USP3876459, etc. disclose a kind of wool fabric softening and finishing auxiliary agent, and then this technology generally has a defect in finishing that is uneven cross-linking, and the organosilicon has not ye...
