Abstract
The invention relates to an anti-mite pure natural composition agent suitable for silk floss and a preparation process and application thereof, wherein the anti-mite pure natural composition agent comprises a natural extract and a solvent which are mixed, wherein the natural extract comprises a sophora flavescens extract; fructus Cnidii extract; and any one or two or all of three extracts of pepper extract, chinaberry bark extract and stemona root extract; the solvent is a hydrophilic organic solvent. The Chinese herbal medicines adopted by the invention are common traditional Chinese medicines collected in pharmacopoeia, are convenient and easy to obtain, have low raw material cost, have insecticidal efficacy, can be used for preventing mites of series products taking silk floss as fillers, such as silk quilt, silk floss back cushion, silk floss pillow and the like, have the mite prevention rate of over 90 percent, have the drug effect higher than that of similar natural mite prevention products in the current market, and simultaneously, have no addition of any harmful chemical auxiliary agent, so that the prepared products are safer, green, healthy and environment-friendly in the using process.
Description
Technical Field
The invention belongs to the field of articles for daily use, and particularly relates to an anti-mite pure natural composition agent suitable for silk floss, a preparation process of the anti-mite pure natural composition agent, and application of the anti-mite pure natural composition agent.
Background
The mites belong to allergic organisms, easily cause allergic reaction of human bodies, and have various diseases such as skin inflammation, bronchial asthma, rhinitis, mange and the like, thereby threatening the health of human bodies.
The mites have dust mites, powder mites, scabies and the like, the mites in families mainly spread out in bedding articles, sofa articles and air, particularly bedding articles, the mites are easier to breed due to the influence of environmental conditions, and the fillers provide convenient conditions for the growth and reproduction of the mites due to fluffy states of the fillers, so that the mites have the following advantages: quilt, pillow, etc. are easy to breed mites. In order to remove mites, most families adopt a water washing method or an air drying method to remove the mites, and silk floss is used as a filler, the silk floss can not be basically washed by water due to the characteristics of the silk, and the ageing of the silk can be increased due to solarization, so that the method is not suitable. Therefore, the silk floss raw material is subjected to anti-mite treatment and is processed into various household products, and the method has practical significance.
However, the anti-mite treatment of textile materials is mainly carried out by adding an anti-mite finishing agent in the production process or carrying out after-finishing by using an auxiliary agent, but silk is natural fiber and can only be carried out by adopting the after-finishing method.
At present, the mite-proof finishing agent adopted in the after finishing is mainly a chemical additive, or a mode of compounding the chemical additive and a natural extract, only the natural extract is used as the mite-proof finishing agent, however, the use of a large amount of the chemical additive is easy to threaten the environmental protection, and meanwhile, people with sensitive skin are easy to cause symptoms such as allergy to some chemical agents, so from the perspective of actual requirements, pure natural mite-proof silk floss and products thereof are needed to enter the market.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a brand-new anti-mite pure natural composition agent suitable for silk floss. The silk floss and silk filling product adopts pure natural traditional Chinese medicine components, can endow silk floss and silk filling products with remarkable mite removing effect, and has the characteristics of environmental protection and safety.
Meanwhile, the invention also relates to a preparation process of the anti-mite pure natural composition agent; the invention also relates to application of the anti-mite pure natural composition agent.
In order to solve the technical problems, the invention adopts the following technical scheme: an anti-mite pure natural composition agent suitable for silk floss comprises a natural extract and a solvent, wherein the natural extract comprises a sophora flavescens extract; fructus Cnidii extract; and any one or two or all of three extracts of pepper extract, chinaberry bark extract and stemona root extract; the solvent is a hydrophilic organic solvent.
Preferably, the natural extract comprises the following components in parts by weight: 5-35 parts of radix sophorae flavescentis, 5-35 parts of fructus cnidii and the balance of one or two or all of pepper, cortex meliae and radix stemonae; the natural extract and a solvent are mixed according to a material-liquid ratio of 1: 100-500, wherein the unit of the natural extract is g, and the unit of the solvent is ml.
