Embodiment 1

[0030] A non-silicon softener, the non-silicon softener is made up of the following parts by weight: 50 parts of tallow, 15 parts of stearic acid, 10 parts of diethylenetriamine, 8 parts of diethyl sulfate, 7 parts of isopropanol , 5 parts of modified polyvinyl alcohol, 3 parts of sodium lauryl sulfate.

[0031] The modified polyvinyl alcohol consists of the following materials in parts by weight: 30 parts of polyvinyl alcohol, 1 part of catalyst, 40 parts of deionized water, 3 parts of trimethylolpropane, 25 parts of butyl acrylate, and 0.6 part of calcium carbonate.

[0032] The catalyst is organic zinc.

[0033] The preparation method of the modified polyvinyl alcohol is as follows: heat polyvinyl alcohol, water, and trimethylolpropane to 95°C until they are completely dissolved, add butyl acrylate and a catalyst for graft copolymerization, cool down to 50°C, and then add Calcium carbonate, stirred evenly, centrifuged to get solid matter, finally dried, pulverized and grou...

Embodiment 2

[0042] The difference between embodiment 2 and embodiment 1 is that the proportion of the non-silicon softener is different, and the others are the same.

[0043] A non-silicon softener, the non-silicon softener is made up of the following parts by weight: 40 parts of tallow, 20 parts of stearic acid, 6 parts of diethylenetriamine, 10 parts of diethyl sulfate, 4 parts of isopropanol , 7 parts of modified polyvinyl alcohol, 5 parts of sodium lauryl sulfate.

Embodiment 3

[0045] Embodiment 3 differs from Embodiment 1 in that the proportion of the non-silicon softener is different, and the others are the same.

[0046] A non-silicon softener, the non-silicon softener is made up of the following parts by weight: 60 parts of tallow, 10 parts of stearic acid, 14 parts of diethylenetriamine, 6 parts of diethyl sulfate, 10 parts of isopropanol , 3 parts of modified polyvinyl alcohol, 1 part of sodium lauryl sulfate.

Abstract

The invention relates to a silicon-free softening agent and a preparation method thereof. The softening agent is prepared from, by weight, 40-60 parts of beef tallow, 10-20 parts of stearic acid, 6-14parts of diethylenetriamine, 6-10 parts of diethyl sulfate, 4-10 parts of isopropyl alcohol, 3-7 parts of modified polyvinyl alcohol and 1-5 parts of sodium lauryl sulfate. By polyvinyl alcohol modification, polyvinyl alcohol can be better applied to the field of textile auxiliary agents to remarkably improve performances of the silicon-free softening agent, and fabrics using the softening agenthave advantages of high hydrophilicity, freeness of stuffiness in wearing of clothes, fluffiness, softness, freeness of oiliness, closeness to human skin and nature, and the like. In addition, the chemical oxygen demand and the biochemical oxygen demand of sewage can be reduced, and biodegradation of organic silicon macromolecules is reduced.

Description

technical field [0001] The invention belongs to the technical field of textile auxiliaries, and in particular relates to a silicon-free softener and a preparation method thereof. Background technique [0002] With the improvement of living standards, people's requirements for various indicators of fabrics are also increasing, such as slippery, soft, supple, smooth feel, good tear strength and hydrophilic properties, etc., so that the fabric finishing products and processes are put forward. higher requirements. [0003] In the technical field of textile auxiliaries, softeners are a large category of textile auxiliaries with many varieties and large output. Softeners are used in the spinning, stretching, reeling, weaving, spinning, spinning and dyeing of chemical fibers. The main function of various softeners is to meet the different handles and styles of various textiles. and request. Today's consumers have higher and higher requirements for the wearing performance of text...
