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
Dyes and their auxiliaries, from the ancient times up to the modern times, are derived from natural plant, animal and mineral extracts, and human-practical natural dyes have been a history of thousands of years. Under the push of industrial revolution, the synthetic dye is practical to replace the natural dye basically in the last hundred years, and becomes a main coloring product for practical application in the printing and dyeing industry. Therefore, the existing antibacterial all-cotton fabric also adopts chemical antibacterial agents and nano silver, nano zinc, nano copper and the like of heavy metals as antibacterial auxiliary agents. However, chemical antibacterial agents are only weak against pathogens, fungi and viruses, and chemical antibacterial agents also produce drug resistance, which results in reduced immune system function of the human body. While 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 skin surface of a human body are killed while germs are killed, the normal human body hazard effect is larger, and the heavy metals such as nano silver, nano zinc, nano copper and the like cause persistent hazard to environmental water bodies.
In recent years, a plurality of companies in China apply the current leading-edge technology, and the improvement and optimization angles of plant component extraction, low-temperature ultrasonic dyeing process and matched antibacterial plant auxiliary agents are started to achieve the antibacterial effect similar to that of the existing antibacterial agent. However, the existing all-cotton fabric is mainly dyed by hand, and adopts a mode of washing and drying for many times, and because the attachment degree of the antibacterial plant auxiliary agent is not high, the antibacterial plant auxiliary agent is required to be dyed for many times or the concentration of the antibacterial plant auxiliary agent is increased so as to obtain a better antibacterial effect, otherwise, the antibacterial component is difficult to be attached to the all-cotton fabric to the greatest extent.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provide an antibacterial plant auxiliary agent for all-cotton fabric, which has the advantages of convenient adhesion of antibacterial components and good antibacterial effect.
The above object of the present invention is achieved by the following technical solutions:
An antibacterial plant auxiliary agent for an all-cotton fabric, wherein the auxiliary agent comprises aqueous polyurethane, acer ginnala Maxim 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; wherein the tea leaf and maple microcapsule powder comprises a surface layer capsule wall made of corn polypeptide and beta-cyclodextrin and a tea leaf and maple capsule core made of tea leaf and maple extract, and the acanthopanax bark 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 acanthopanax bark capsule core made of acanthopanax leaf extract.
By adopting the technical scheme, the aqueous polyurethane in the auxiliary agent is prepared by adopting an emulsification method, and the aqueous polyurethane can promote the dispersion of the Acer ginnala Maxim microcapsule powder and the Acanthopanax senticosus microcapsule powder in the dye liquor during dyeing so as to graft and crosslink the Acer ginnala Maxim microcapsule powder, the Acanthopanax senticosus microcapsule powder and cotton fibers of the all-cotton fabric, thereby improving the attachment rate of the auxiliary agent on the all-cotton fabric; after dyeing is finished, the Acer ginnala Maxim capsule core wrapped by the surface capsule wall is subjected to primary antibacterial, the Acer ginnala Maxim extract contains effective antibacterial components such as maple tannin, gallic acid and the like, and under the embedding of corn polypeptide and beta-cyclodextrin, the Acer ginnala Maxim extract not only can be grafted and crosslinked on the surface of the cotton fabric through waterborne polyurethane, but also can maintain better thermal stability and structural stability in the post-treatment process, so that the effective components are slowly released in the porous surface capsule wall formed by the beta-cyclodextrin to play a role in long-acting antibacterial; then, the acanthopanax root capsule core sequentially wrapped by the outer capsule wall and the inner capsule wall is subjected to combined antibiosis, and the outer capsule wall made of chitosan and porous starch is additionally arranged on the outer capsule wall, so that the acanthopanax root microcapsule powder is promoted to be adsorbed in the weaving gaps of the all-cotton fabric while the slow release effect is not influenced, and substances such as bacteria penetrating through the all-cotton fabric are adsorbed on the pores of the outer capsule wall, so that the bacteriostasis efficiency is further improved; after the auxiliary agent is washed by water for a plurality of times, the inhibition rate of the auxiliary agent on staphylococcus aureus is more than or equal to 99.9 percent, the inhibition rate of the auxiliary agent on escherichia coli is more than or equal to 99.9 percent, the inhibition rate of the auxiliary agent on candida albicans is more than or equal to 99.9 percent, and the auxiliary agent has the effects of inhibiting the growth of pathogenic bacteria and keeping probiotics stable.
Further, the aqueous polyurethane is a perfluoropolyether glycol modified polyurethane solution, and the solid content is 30-40%.
Further, the preparation of the Acer ginnala Maxim microcapsule powder comprises the following steps,
S11, dissolving corn polypeptide and beta-cyclodextrin in water to obtain a surface specific cyst solution;
S12, sequentially freezing the Acer ginnala Maxim leaves by liquid nitrogen, carrying out jet milling and sieving treatment to obtain Acer ginnala Maxim leaf particles with 100-140 meshes, mixing the Acer ginnala Maxim leaf particles with absolute ethyl alcohol, sequentially carrying out ultrasonic oscillation, heating reflux, suction filtration and concentration treatment, and 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 performing shearing, homogenizing and spray drying to obtain Acer ginnala Maxim microcapsule powder.
Further, in S11, the mass ratio of the corn polypeptide to the β -cyclodextrin is 1.00: (1.30-1.80), wherein the total concentration of the corn polypeptide and the beta-cyclodextrin in water is 20-30%wt.
