Problems solved by technology

[0040] ① The first generation of hydroxy silicone oil and methyl silicone oil have darkening effect, no yellowing, no phenol yellowing, but no hydrophilicity, no good hand finishing effect, poor application stability
[0041] ②The second-generation amino silicone oil emulsion has a darkening effect and a good hand finishing effect, but the heat yellowing and phenol yellowing are very large, basically has no hydrophilicity, and the application stability of the working fluid is not good
[0042] ③The third-generation polyether modified silicone oil emulsion has excellent hydrophilicity, excellent application stability, no thermal yellowing, no phenolic yellowing, but no darkening effect, no good hand finishing effect
The third-generation polyether-modified amino silicone oil emulsion has good application stability and general hydrophilicity (cannot achieve instant hydrophilicity), but thermal yellowing and phenolic yellowing still exist, and there is no deepening effect
Hand finishing is not as good as amino silicone oil, and the long-lasting hydrophilicity is still not solved
[0043] ④ The fourth-generation amino polyether block silicone oil emulsion has good application stability, good handle finishing effect, general hydrophilicity, no satisfactory darkening effect, and thermal yellowing and phenolic yellowing still exist , still has not solved the long-lasting hydrophilicity, and still has not solved the contradiction between high-touch finishing effect and fast hydrophilicity

Embodiment 1

[0077] Embodiment 1. Research on deepening effect

[0078] Based on the deepening principle of "high polymers must be homogeneous, uniform and continuous film formation", the applicant found through experiments that there are two methods for obtaining uniform and continuous film formation on fabrics that can be verified experimentally. Method one is: use large, medium and small molecular weight end epoxy silicone oil and amino polyether amine / tertiary ammonium polyether ammonium salt orthogonal experiment; method two is: use medium and large / ultra-large molecular weight end epoxy silicone oil and amino polyether amine / Tertiary ammonium polyether ammonium salt.

[0079] Accordingly, the applicant designed the orthogonal experimental parameters according to the above method 1 and method 2 as described in Table 1 and Table 2 below.

[0080] Table 1. Method 1: Orthogonal experiment with large, medium and small molecular weight terminal epoxy silicone oil and amino polyether ami...

Embodiment 2

[0092] Example 2. Research on the principle of hand feeling finishing, the principle of lasting instant water absorption and the principle of thermal yellowing and phenol yellowing

[0093] The applicant found through research that the principle of hand finishing lies in: fully and evenly adsorbed on the surface of the fabric, and homogeneous, uniform and continuous film formation. Through method one experiment and method one experiment conclusion, it is found that the adsorption capacity (uniform adsorption capacity) of the quaternary ammonium salt cation is far stronger than the weak cation after acidification of primary amine, secondary amine, and tertiary amine.

[0094] Therefore this invention has selected tertiary ammonium polyether ammonium salt, and all become quaternary ammonium salt cations after its reaction.

[0095] In addition, it has been found through research that the principle of long-lasting and instant water absorption lies in: quaternary ammonium polyethe...

[0100] In this embodiment, a polyquaternium polyether polydimethylsiloxane with a molecular weight between 30,000 and 80,000 is provided, and the polyquaternium polyether polydimethylsiloxane is represented by the following general formula I:

[0101]

[0102] where the R 1 selected from -CH 3 、-C 2 h 5 or -C 4 h 9 one of - from Cl - , Br - , I - , CH 3 COO - One of them; a is an integer selected from 2 to 3; b is an integer selected from 30 to 100, such as 30, 35, 40, 45, 50, 55, 60, 65, 70, 80, 90, 100, etc.

[0103] The synthesis route of the polyquaternary ammonium polyether polydimethylsiloxane is as follows.

[0104] Step 1. Preparation of Intermediate 1: 1,3-Epoxypropyloxypropyldisiloxane

[0105]

[0106] Under the condition of 45~85℃, using 1% isopropanol solution of chloroplatinic acid as catalyst (the dosage is 0.05~0.1% of the total weight of the system), to 1,1,3,3-tetramethyldihy...

Abstract

The invention provides poly quaternary ammonium polyether polydimethylsiloxane, a preparation method thereof and a hand feeling finishing agent using the poly quaternary ammonium polyether polydimethylsiloxane. The molecular weight of the poly quaternary ammonium polyether polydimethylsiloxane is 30000-80000; and the poly quaternary ammonium polyether polydimethylsiloxane is shown in the general formula I. A synthesis technology provided by the invention is suitable for industrial mass production by using novel raw materials in coordination with a suitable catalyst synthesis technology, meanwhile solves the problem that the instant hydrophilicity of cotton fiber fabrics in the prior art loses after high temperature setting, and improves the hand feeling finishing effect without problems such as yellowing and phenolic yellowing. In addition, synthesis process conditions involved in the invention are compatible, and the product working fluid has relatively high stability in use.

Description

technical field [0001] The invention relates to the field of functional finishing agents for textiles, in particular to a polyquaternary amino polyether polydimethylsiloxane, a preparation method thereof and a hand finishing agent. Background technique [0002] At present, the development of global textile silicone materials has gone through four stages of development: [0003] In the first stage, non-hydroxyl silicone oil emulsion and methyl silicone oil emulsion, the structural characteristics are as follows: [0004] Hydroxy silicone oil: Among them, n=5~100000; [0005] Methicone: Wherein m=5~100000. [0006] Since hydroxy silicone oil and methyl silicone oil are non-ionic in nature, they have no directional adsorption effect on the fiber, and their adsorption on the fiber surface is uneven and the adsorption amount is insufficient, resulting in unsatisfactory finishing effect. At the same time, since hydroxy silicone oil and methyl silicone oil cannot be disperse...
