Problems solved by technology

[0004] However, the conventional cotton softener is weakly cationic, and when it is bathed with anionic color paste, it is very easy to react with the color paste, forming flocculent precipitates and contaminating the cloth surface, causing great trouble to production

manufacture example 1

[0021] Preparation of Silicone Emulsion:

[0022] Take 2.5 grams of HD-104 (N-cyclohexyl-γ-aminopropylmethyldimethoxysilane) and add 0.25 grams of water, take 1.5 grams of GP-108 (3-piperazinylpropylmethyldimethoxy Silane) was added with 0.15 g of water, stirred evenly, and hydrolyzed for 20 minutes. Take 100g of D4 (octamethylcyclotetrasiloxane), 3g of ethyl cellulose, mix in the hydrolyzed HD-104 and GP-108, stir and heat up to 60-70°C, add 0.02g of lithium hydroxide, and continue to heat up To 120-130 ℃, heat preservation reaction for 3-4 hours, vacuumize to remove low molecular substances, and then lower the temperature to obtain amino silicone oil.

[0023] Take 20 grams of the self-made amino silicone oil obtained above, add 3.6 grams of XP-30, 4.4 grams of XP-70, and 2 g of hydroxyethylethylenediamine, and stir well; divide 72 grams of deionized water mixed with glacial acetic acid into several times After adding a small amount of water each time, stir at a high speed...

Abstract

The invention provides a preparation method of a hydrophilic softener for cotton with good compatibility. The method comprises the following steps of adding octamethylcyclotetrasiloxane and ethyl cellulose after hydrolyzing N-cyclohexyl-gamma-aminopropyl methyl dimethoxy silane and 3-piperazinyl propyl methyl dimethoxy silane to prepare amino-modified silicone oil; adding emulsifier and hydroxyethyl ethylenediamine into the prepared amino-modified silicone oil for uniform mixing, slowly adding a certain amount of deionized water mixed with glacial acetic acid to prepare an organic silicon emulsion; and finally uniformly mixing the organic silicon emulsion, octadecyl dimethylamine ethyl lactone and water.

Description

technical field [0001] The invention relates to the technical field of softener production, in particular to a method for preparing a hydrophilic softener for cotton with good compatibility. Background technique [0002] Cotton has many advantages such as breathable and sweat-absorbing, comfortable and soft, good warmth retention, antistatic, strong alkali resistance, and good dyeability. It has always been one of the most used natural fibers, and the textile dyeing and finishing process of cotton fabrics is also relatively mature. [0003] In the finishing process of cotton fabrics, softeners and anionic substances are often used in a bath together. For example, with the continuous improvement of customer requirements, many knitted cotton fabrics now need to use anionic colorant for coloring in order to adjust the color light. At the same time, in order to save the process, coloring is usually carried out at the same time as the softener, that is, the anionic colorant and s...
