[0004] The patent application No. 200710011759.X "An Antibacterial Fabric Finishing Solution Containing Chitosan, Preparation Method and Its Application Method" provides a fabric finishing solution containing chitosan, which is composed of chitosan, acetic acid, epoxy chlorine Composed of propane and water, it is soluble under weakly acidic conditions and has good antibacterial effect, but after compounding with non-ionic surfactants such as other softeners, chitosan will precipitate under neutral or alkaline conditions, thus the antibacterial function disappears
[0005] The patent "Water-Soluble Chitosan Quaternary Ammonium Salt Antibacterial Finishing Agent and Its Preparation and Application" with the application number of 200910200566.8 is to introduce hydrophilic groups into the amino groups of chitosan, so that it can be dissolved in water, but its configuration process is complicated , and the requirements for the control ability of various parameters in the process are relatively high, so it is difficult to carry out industrial production and application

Embodiment 1

[0032] A preparation method for a multifunctional fabric softener, comprising the steps of:

[0033] One, the preparation of water-soluble chitosan

[0034] Stir chitosan and isopropanol to reflux, heat in a water bath, raise the temperature to 30°C, slowly add the modifier dimethyl sulfate dropwise; after stirring evenly, raise the temperature to 70°C, and react for 12 hours; after the reaction is completed, stop heating And the solution was cooled, filtered with suction, and distilled under reduced pressure to obtain rough water-soluble chitosan. Wash with ethanol-acetone solution, filter with suction, and dry to obtain refined water-soluble chitosan.

[0035] Among them, the particle size of chitosan is 80 mesh, the degree of deacetylation is 85%; the mass ratio of chitosan to isopropanol is 1:10; the molar ratio of chitosan to modifier is 1:3; The volume ratio of ethanol to acetone is 0.4:1.

Abstract

The invention provides a multifunctional softener and a preparation method for the same. The multifunctional softener is composed of amino silicon oil, a compound emulsifier, water-soluble chitosan and water, wherein amino silicon oil is added in the compound emulsifier, and the mass ratio of the amino silicon oil to the compound emulsifier is 1:(0.2-0.8); then the water-soluble chitosan is added, and the added amount is 1-8% of the mass of the mixed solution of the amino silicon oil and the compound emulsifier; finally, water is added, and the mass of water is 10-50% of the total mass of the mixed solution aforementioned. The preparation method comprises the following steps of: preparation for the water-soluble chitosan, preparation for the compound emulsifier, and preparation for the multifunctional fabric softener. The multifunctional integrated softener obtained after compounding has all the excellent characteristics of modified chitosan on the basis of a soft function. Compared with the existing softener with an anti-bacterial function, the preparation process flow is simple, a complex configuration process is not required, and industrialized production is easy to realize.

Description

technical field [0001] The invention belongs to the technical field of textile post-finishing auxiliaries, and in particular relates to a multifunctional fabric softener and a preparation method thereof. Background technique [0002] With the development of textile technology, more and more textiles can be processed through different finishing processes to make them have corresponding functions, thereby increasing the added value of textiles. Soft finishing of all kinds of textiles, especially bedding textiles, is a post-finishing process that must be carried out. Therefore, the selection of softeners is very important. However, consumers require textiles to have antibacterial and anti-mite related functions on the basis of satisfying the hand feel. In order to meet these functions, some products separately add antibacterial agents in the finishing process for antibacterial finishing, which is complicated and costly. However, most of the softeners on the market have a singl...
