Problems solved by technology

To sum up, the existing finishing methods have the following deficiencies: one is that the methods of adhesive bonding and blend spinning are mainly used, which have certain defects in practicality, comfort, durability and functional diversification. It is difficult to get large-scale application; second, the finishing function is single, and there is no integrated technical solution including antibacterial, deodorant, insect repellent, fragrance, anti-wrinkle, washable and other functional finishing, which does not meet the needs of consumers in modern society; the third is natural There are few types of health care textile products
[0006] To sum up, the vast majority of microcapsule and nanocapsule technology on fabrics currently use adhesive coating methods to directly bond the capsules to the fibers, and there is only a simple physical adhesion between the capsules and the fabric. Function, this method has the disadvantages of poor capsule adhesion and poor washability. At the same time, the formaldehyde problem caused by the use of 2D resin to improve the wrinkle resistance of fabrics has not been properly resolved, leaving technical problems for fabric finishing.

[0058] 1. Oxidative degradation of chitosan

[0059] Weigh a certain amount of chitosan and add it to a three-necked flask, heat it in a constant temperature water bath at 50°C, dissolve it with 2.5% acetic acid solution, stir it at 400r / min for 5 minutes, and then add an appropriate amount of 4% H 2 o 2 The solution was reacted for 4 hours. After the reaction, the pH value of the reaction system was adjusted to 7.0 with 10% NaOH solution, and the neutralized reaction solution was added dropwise into acetone twice the volume of the reaction solution under stirring conditions for precipitation. After standing overnight, suction filter and dry to obtain the degradation product for future use.

Abstract

The invention discloses a blumea oil microcapsule textile composite finishing agent and use thereof. Gelatin or acacia of natural polymers is used the main ingredient of a wall material, the blumea oil serving as a Chinese medicinal material is used as a core material, and complex coacervation is adopted to prepare an blumea oil microcapsule aqueous emulsion; a shrink-resistance crosslinker and a catalyst are added to be combined with the blumea oil microcapsule aqueous emulsion into a multifunctional blumea oil microcapsule textile composite finishing agent; researches on the use of blumea oil microcapsules in textile finishing are carried out; and a novel cross linked graft method is used to perform the microcapsule finishing of textiles to form chemical bonds between the microcapsules and the textiles though the shrink-resistance crosslinker and free formaldehyde molecules in 2D resin further participate in a cross-linking and curing reaction as a microcapsule curing agent, so the textiles achieve a long lasting antibacterial and health-care function, a shrink-resistance function and low formaldehyde release content performance.

Description

technical field [0001] The invention belongs to the field of microcapsule preparation technology and textile technology, and in particular relates to a composite finishing agent of mugwort leaf oil microcapsule fabric and its application. Background technique [0002] In recent years, with the development of society and the improvement of people's living standards, people have higher and higher requirements for the comfort and functionality of textiles, and the awareness of disease prevention and health care has also been continuously enhanced.
