Abstract

The invention relates to a preparation method of a surface layer material of a cotton sanitary product, and belongs to the technical field of sanitary materials. According to the preparation method disclosed by the invention, tea polyphenols are adsorbed on the surfaces of cotton fibers through chitosan, the characteristic that adjacent-position phenolic hydroxyl groups in catechin type moleculesas main active molecules in tea polyphenols are high in activity and easy to dehydrogenate to be converted into carbonyls to act with bacteria, so that the bacterium resisting effects can be achieved,harmful free radicals are eliminated, and the purposes of resisting bacteria and removing odor can be achieved, is used, and the tea polyphenols cooperate with the chitosan to achieve the effects ofefficiently killing bacteria and removing odor; the tea polyphenols and the chitosan are compounded with superfine-denier acrylic yarns which are fine in capillaries and large in number and can significantly strengthen the capillary wicking effects of fabrics and further improve the air permeability and the moisture conductivity properties of the fabrics, and a bacterium-restraining moisture-conducting fiber net is formed through carding and netting; then bamboo fibers and sarcandra glabra sirospun are closely spun and compounded, and a moisture absorbing fiber net is formed through carding and netting; and the bacterium-restraining moisture-conducting fiber net and the moisture absorbing fiber net are combined to form the surface layer material which is high in dampness gradient continuity, air and moisture permeability is improved, and the comfort degree is increased.

Description

technical field [0001] The invention relates to a method for preparing a surface layer material of a cotton hygiene product, belonging to the technical field of hygiene materials. Background technique [0002] The skin-friendliness and dryness of the top layer of absorbent hygienic materials are important indicators for consumers to choose products. At present, the surface layer of absorbent hygienic materials on the market mostly adopts thermoplastic fibers such as ES (polyolefin fiber), polypropylene or polyethylene terephthalate, and pure cotton as raw materials. Chemical fiber is poor skin-friendly, and its petroleum-based raw materials are non-renewable, and it is difficult to degrade after being discarded; pure cotton material is skin-friendly and soft, but because it does not have antibacterial properties, if the moisture cannot be removed in time after moisture absorption, it will easily breed bacteria. [0003] The hygienic materials used for the surface layer of d...
