Problems solved by technology

[0003] There are two main methods commonly used in the current industrial anti-felting process: one is the traditional chlorinated wool anti-felting process, which can release adsorbed organic halides (ie AOX value) during processing, which does not meet Cleaner Production Requirements
The second is to use non-chlorinated high polymer methods, such as polyurethane coating for wool anti-felting finishing. This method is not accepted by the market because it makes the wool fabric feel hard.
The sol prepared by organically modified metal alkoxide can be condensed to form a gel under certain conditions, and then dried to form a firm transparent porous oxide film on the surface of the wool fiber, so as to achieve a good anti-felting effect. However, the wool fabric treated with the sol prepared by this metal alkoxide is still hard, and the wool fabric is damaged to a certain extent due to the high baking temperature.

Embodiment 1

[0030] Preparation of polyetheramine (molecular weight 400) modified γ-(2,3-glycidoxy)propyltrimethoxysilane.

[0031] At 80°C, 29.5 grams of γ-(2,3-glycidoxy)propyltrimethoxysilane was added dropwise to 52.46 grams of polyetheramine with a molecular weight of 400 within 0.5 hours. Keep the polyetheramine solution stirred evenly under the heating condition of 80°C. After the dropwise addition is completed, continue stirring under the same conditions for 2 hours to obtain the polyetheramine modified γ-(2,3-glycidoxy)propyl Precursor of trimethoxysilane.

Embodiment 2

[0033] Preparation of polyetheramine (molecular weight: 2000) modified γ-(2,3-glycidoxy)propyltrimethoxysilane.

[0034] At 85°C, 20 grams of γ-(2,3-glycidoxy)propyltrimethoxysilane was added dropwise to 177.9 grams of polyetheramine with a molecular weight of 2000 within 1 hour. Keep the polyetheramine solution stirred evenly under the heating condition of 85°C. After the dropwise addition is completed, continue stirring under the same conditions for 1.5 hours to obtain the polyetheramine modified γ-(2,3-glycidoxy)propyl Precursor of trimethoxysilane.

Embodiment 3

[0036] (1) Preparation of sol

[0037] will contain 40ml water and 40ml C 1-4 Add the alcohol aqueous solution of alcohol dropwise to 20ml of the polyetheramine modified precursor solution in Example 1, and complete the dropwise addition within 1 hour under normal temperature stirring conditions, then continue to stir for 1 hour, adjust the pH to 3-4, and place it for aging After several hours of curing, a transparent stable sol with a hydrolyzate content greater than 50% was obtained.

[0038] (2) Anti-felting finish

[0039] Dip all wool gabardine twice in the above sol finishing solution and roll twice, the pressure is 3Kg / cm 2 Then dry in an oven at 80°C for 10 minutes, wash with water and then dry for the second time.

[0040] (3) Anti-felting effect test

[0041] Referring to the IWS TM NO.31 test standard and method, the felt shrinkage can reach within 1-2%.

[0042] (4) Evaluation of softening effect

[0043] Based on subjective evaluation, the softness of the cl...

Abstract

The related preparation method for polyetheramine-modified gamma-(2, 3-epoxypropoxy)propyl trimethoxy silicane sol comprises: preparing the predecessor with gamma-(2, 3-epoxypropoxy) propyl trimethoxy silicane and polyetheramine; then reacting to acid, alcohol and water. This invention applies low-temperature setting technique and combines rolling-drying-baking process to endow the woven fabric with well hand feeling and super resistance to wash and shrinkage.

Description

technical field [0001] The invention belongs to the technical field of chemical engineering, and the fabrics specifically involved are blended wool fabrics and all-wool fabrics containing wool components, and the related method is a soft and washable low-temperature anti-felting finishing of the above-mentioned fabrics by using a sol-gel method. A polyetheramine modified silane sol for soft and anti-felting finishing of wool fabrics. Background technique [0002] With the continuous improvement of people's consumption level and the acceleration of the pace of daily work, it has become an important topic in the field of textile research in the world to solve the felting problem of wool fabrics as soon as possible and make them machine-washable and anti-felting. [0003] There are two main methods commonly used in the current industrial anti-felting process: one is the traditional chlorinated wool anti-felting process, which can release adsorbed organic halides (ie AOX value) ...
