Abstract
The invention relates to an antibacterial plant auxiliary agent for an all-cotton fabric, which comprises waterborne polyurethane, acer ginnala microcapsule powder accounting for 40-60% of the total weight of the waterborne polyurethane, and acanthopanax microcapsule powder accounting for 40-60% of the total weight of the waterborne polyurethane. The aqueous polyurethane in the assistant can promote the acer ginnala micro-capsule powder and the acanthopanax senticosus micro-capsule powder to be dispersed in the dye solution so as to graft and cross-link the acer ginnala micro-capsule powder and the acanthopanax senticosus micro-capsule powder with cotton fibers of a full cotton fabric, improve the attachment rate of the assistant on the full cotton fabric, and have the effects of inhibiting the growth of pathogenic bacteria and keeping the stability of probiotics.
Description
Technical Field
The invention relates to the technical field of dyes, in particular to an antibacterial plant auxiliary agent for all-cotton fabrics.
Background
The dyes and the auxiliary agents thereof from ancient times to recent times are all from natural plants, animals and minerals, and the natural dyes practical for human beings have been used for thousands of years. Under the push of the industrial revolution, synthetic dyes have basically replaced the practicality of natural dyes in nearly a century, and become the main coloring products for practical application in the printing and dyeing industry. Therefore, chemical antibacterial agents, heavy metal nano silver, nano zinc, nano copper and the like are also mostly adopted as antibacterial aids in the existing antibacterial all-cotton fabric. However, chemical antibacterial agents only target germs, have weak inhibitory action on fungi and viruses, and also cause drug resistance, resulting in a decrease in the immune system function of the human body. Although the broad-spectrum antibacterial effect of heavy metals such as nano silver, nano zinc, nano copper and the like is good, all probiotics on the surface of human skin can be killed while germs are killed, the effect of normal harm to human bodies is larger, and the heavy metals such as nano silver, nano zinc, nano copper and the like cause lasting harm to environmental water.
In recent years, domestic companies apply modern leading-edge technology, starting from the aspects of plant component extraction, low-temperature ultrasonic dyeing process and improvement and optimization of matched antibacterial plant auxiliary agents, so as to achieve the antibacterial effect similar to that of the existing antibacterial agent. However, the existing all-cotton fabric is mainly dyed by hand, a mode of washing and airing for many times is adopted, and the adhesion degree of the antibacterial plant auxiliary agent is not high, so that the all-cotton fabric needs to be dyed for many times or the concentration of the antibacterial plant auxiliary agent is increased to obtain a good antibacterial effect, otherwise, the antibacterial component is difficult to be attached to the all-cotton fabric to the maximum extent.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provides an antibacterial plant auxiliary agent for all-cotton fabrics, which has the advantages of convenient attachment of antibacterial components and good antibacterial effect.
The above object of the present invention is achieved by the following technical solutions:
an antibacterial plant assistant for all-cotton fabrics comprises aqueous polyurethane, acer ginnala microcapsule powder accounting for 40-60% of the total weight of the aqueous polyurethane and acanthopanax microcapsule powder accounting for 40-60% of the total weight of the aqueous polyurethane; the acer ginnala microcapsule powder comprises a surface layer capsule wall made of corn polypeptide and beta-cyclodextrin and an acer ginnala capsule core made of an acer ginnala extract, and the acer ginnala microcapsule powder comprises an outer layer capsule wall made of chitosan and porous starch, an inner layer capsule wall made of corn polypeptide and beta-cyclodextrin and an acer ginnala capsule core made of an acer ginnala extract.
By adopting the technical scheme, the aqueous polyurethane in the auxiliary agent is prepared by adopting an emulsification method, and during dyeing, the aqueous polyurethane can promote the acer ginnala micro-capsule powder and the acanthopanax senticosus micro-capsule powder to be dispersed in a dye solution so as to graft and crosslink the acer ginnala micro-capsule powder and the acanthopanax senticosus micro-capsule powder with cotton fibers of a full-cotton fabric, so that the attachment rate of the auxiliary agent on the full-cotton fabric is improved; after dyeing is finished, primary antibiosis is carried out on the Acer ginnala Maxim capsule core wrapped by the surface capsule wall, the Acer ginnala Maxim extract contains effective antibacterial ingredients such as Acer maple tannin, gallic acid and the like, under the embedding of corn polypeptide and beta-cyclodextrin, the Acer ginnala Maxim extract can be grafted and crosslinked on the surface of all-cotton fabric through waterborne polyurethane, and better thermal stability and structural stability can be kept in the post-treatment process, so that the effective ingredients are slowly released in the porous surface capsule wall formed by the beta-cyclodextrin, and long-acting antibiosis is achieved; then the acanthopanax bark capsule core sequentially wrapped by the outer-layer capsule wall and the inner-layer capsule wall is combined for antibiosis, the outer-layer capsule wall made of chitosan and porous starch is additionally arranged on the outer layer, so that the acanthopanax bark micro-capsule powder can be adsorbed in weaving gaps of the all-cotton fabric without influencing the slow release effect, and substances such as bacteria and the like penetrating through the all-cotton fabric can be adsorbed to pores of the outer-layer capsule wall, and the bacteriostasis efficiency is further improved; after being washed by water for many times, the auxiliary agent provided by the invention has the inhibition rate of more than or equal to 99.9% on staphylococcus aureus, more than or equal to 99.9% on escherichia coli, and more than or equal to 99.9% on candida albicans, and has the effects of inhibiting the growth of pathogenic bacteria and keeping probiotics stable.
Further, the aqueous polyurethane is a polyurethane solution modified by perfluoropolyether diol, and the solid content is 30 to 40 percent.
Further, the preparation of the acer ginnala micro-capsule powder comprises the following steps,
s11, dissolving corn polypeptide and beta-cyclodextrin in water to obtain a surface layer sacculus comparing solution;
s12, sequentially freezing Acer ginnala Maxim leaves by liquid nitrogen, carrying out airflow crushing and sieving treatment to obtain Acer ginnala Maxim leaf granules of 100-140 meshes, mixing the Acer ginnala Maxim leaf granules with absolute ethyl alcohol, sequentially carrying out ultrasonic oscillation, heating reflux, suction filtration and concentration treatment, and then mixing the concentrated solution with an oily emulsifier to obtain an Acer ginnala Maxim extract;
s13, mixing the surface layer capsule wall solution and the acer ginnala Maxim extract, and sequentially carrying out shearing, homogenizing and spray drying treatment to obtain acer ginnala Maxim microcapsule powder.
