Embodiment 1

[0036] A γ-(2,3-glycidoxy)propyltrimethoxysilane sol was prepared.

[0037] At room temperature, weigh 56.2 grams of γ-(2,3-glycidoxy)propyltrimethoxysilane (GPTMS), 180 grams of industrial ethanol, and 45 grams of water; 1 L of dilute hydrochloric acid to adjust the pH value of the solution to 3-4; vigorously stir evenly for 5 hours, then let it stand for 2 hours for later use.

Embodiment 2

[0039] Preparation of amino silicone oil (Dow corning 8600) emulsion.

[0040] Add 140 grams of water, 16 grams of SAS, and 4 grams of glacial acetic acid in sequence, stir evenly and heat up to 40°C, then stir rapidly for 20 minutes, add 40 grams of amino silicone oil dropwise, continue stirring for 15 minutes, and adjust the pH value to 4~ 5. Cool down to room temperature and leave it for a period of time before use.

Embodiment 3

[0042] The amino silicone oil emulsion in 50 grams of embodiment 2 is dripped in the gamma-(2,3-epoxypropoxyl group) propyltrimethoxysilane sol base solution in 100 grams of embodiment 1, in the process of dropping Keep the bottom liquid at room temperature and stir at a constant speed, drop it within 20 minutes, continue to stir for 1 hour, adjust the pH to 3-4, and leave it for several hours to obtain a transparent and stable modified sol, then seal it and store it in isolation from the air. use.

Abstract

The invention relates to an amino silicone oil emulsion modified silane sol and the manufacture method and the use. It adopts amino silicone oil emulsion and gamma-(2, 3- epoxy oxypropyl group) propyl trimethoxyl group silane sol to mix to form modified sol finishing agent. The invention could lower film forming and solidifying temperature, and make the woven fabric have good handle and excellent wear and felt resistance effect.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to an anti-felting finishing agent capable of treating blended wool fabrics and all wool fabrics containing wool components. Background technique [0002] There are two main methods commonly used in the current industrialized anti-felting process: one is the traditional chlorination method (also known as chlorine oxidation method) wool anti-shrinkage processing technology, wool is prone to yellowing and elastic damage during the processing process And other disadvantages, especially the organic chlorine (AOX) pollution in wastewater discharge, which limits the application of this technology. The second is to use non-chlorinated high polymer methods, such as polyurethane coating to anti-felt the wool. The disadvantage of this method is that the wool fabric feels hard. The sol prepared by organically modified metal alkoxide can be condensed to form a gel under c...
