Problems solved by technology

However, garlic essential oil and eucalyptus essential oil are volatile and have poor thermal stability. They are easily deteriorated by oxygen, heat and light in the environment, which reduces the mosquito repellent effect of microcapsules and shortens the container period of microcapsules.
[0005] In addition, the existing microcapsule finishing agent does not have enough affinity with textiles, and it is very easy to fall off from the surface of textiles.

Embodiment 1

[0035] Embodiment 1, the mosquito repellent effect that contains the microcapsule of different plant essential oil combination

[0036] Add 3g of microcapsules containing the following combinations of different plant essential oils per 1Kg of textiles, use polyacrylamide as the binder, and finish the textiles through a finishing process of dipping and rolling. According to the repellent method in GB / T30126-2013 The textiles finished with microcapsules were subjected to a mosquito repellent test, and the test results are shown in Table 1 below.

[0037] Table 1 Test results

[0038]

[0039]

[0040] It can be seen from the above table 1 that the textiles finished with microcapsules prepared by the combination of mugwort essential oil and vetiver essential oil have a strong repelling effect on mosquitoes, and the repellent rate can reach more than 70%, especially after the compounding of 1:0.3 The textiles finished with the obtained microcapsules have the highest repelle...

Embodiment 2

[0042] Embodiment 2, a kind of microcapsules for finishing after weaving

[0043] The microcapsules described in Example 2 of the present invention consist of a core material and a capsule wall in a weight ratio of 0.3:1, the core material includes 15 parts of plant essential oils and 0.6 parts of L-methionyl glycine hydrochloride, and the capsule wall It is prepared from octenyl succinic esterified starch, nano-microcrystalline cellulose and sodium caseinate in a weight ratio of 1:0.2:0.6, and the plant essential oil is composed of Artemisia argyi essential oil and vetiver essential oil in a weight ratio of 1:0.3 composition.

[0044] Preparation:

[0045] A) dissolving octenyl succinate starch in purified water to prepare an aqueous solution of octenyl succinate starch with a mass fraction of 2.0%;

[0046]B) dissolving sodium caseinate in water to prepare an aqueous solution of sodium caseinate with a mass fraction of 6.0%, dissolving nanocrystalline cellulose in the aque...

Embodiment 3

[0050] Embodiment 3, a kind of microcapsules for finishing after weaving

[0051] The microcapsules described in Example 3 of the present invention are composed of a core material and a capsule wall in a weight ratio of 0.2:1, the core material includes 10 parts of plant essential oils and 0.2 parts of L-methionyl glycine hydrochloride, and the capsule wall It is prepared from octenyl succinic esterified starch, nano-microcrystalline cellulose and sodium casein at a weight ratio of 1:0.1:0.3, and the plant essential oil is made of Artemisia argyi essential oil and vetiver essential oil at a weight ratio of 1:0.2 composition.

[0052] The preparation method is as in Example 2.

Abstract

The invention belongs to the field of textile finishing agents and particularly relates to a microcapsule for a textile after-finishing as well as a preparation method and application thereof. The microcapsule consists of a core material and a capsule wall according to the weight ratio of (0.2-0.6):1, wherein the core material comprises 10-20 parts by weight of plant essential oil and 0.2-1 part of L-methionylglycine hydrochloride; the capsule wall is prepared from starch octenylsuccinate, nano-microcrystalline celluloses and casein sodium according to the weigh ratio of 1:(0.1-0.3):(0.3-0.8). The microcapsule provided by the invention has good mechanical strength and has the advantages of being natural, safe and degradable; the microcapsule has good affinity with a textile product; a test shows that the textile product finished by the microcapsule is lasting in fragrance, the repelling rate reaches 89 percent, and a mosquito repelling effect is very strong.

Description

technical field [0001] The invention belongs to the field of textile finishing agents, and in particular relates to a microcapsule for textile finishing and a preparation method and application thereof. Background technique [0002] In recent years, due to the continuous emergence of new processing technologies for textile materials, functional textiles have developed rapidly and become an important high-tech industry, among which anti-mosquito textiles have become one of the research hotspots of functional textiles in recent years. [0003] Microcapsule technology is a protective technology that encapsulates reactive, volatile, sensitive or odorous substances (core materials) through film-forming materials (wall materials) to form tiny particles. The process is called microencapsulation, and the tiny particles formed are called microcapsules. Anti-mosquito microcapsules refer to a kind of tiny particles formed by encapsulating various mosquito repellents and insecticides t...
