Preparation method of sanitation product with incompletely-degreased pure cotton non-woven fabric

Abstract

The invention relates to the field of sanitation products and provides a preparation method of a sanitation product with an incompletely-degreased pure cotton non-woven fabric. The defects are overcome that a preparation technology of a pure cotton non-woven fabric in the prior art is complex, energy consumption is high, and only complete degreasing can be conducted. The sanitation product with the incompletely-degreased pure cotton non-woven fabric is prepared in the mode that a fluid-permeability surface layer, an absorber and a non-fluid-permeability bottom layer are prepared and integrallycompounded. A method for preparing the fluid-permeability surface layer comprises the specific steps of 1) opening and impurity removal for raw cotton; 2) combing; 3) incomplete degreasing; 4) whiteness improvement; 5) laccase treatment; 6) washing with water, drying and secondary impurity removal, wherein during secondary impurity removal, impurities with the diameters of 0.5 millimeter or beloware removed through a foreign fiber sorting machine; 8) net formation through carding; 9) spunlace, wherein the high-pressure water flow is adopted for snarling a cotton net obtained through treatment in step 8); 10) drying, wherein a next treatment working process is executed.

Description

technical field [0001] The invention relates to the field of sanitary products, in particular to a method for preparing sanitary products containing incompletely degreased pure cotton non-woven fabrics. Background technique [0002] The structure of traditional sanitary products generally includes a liquid-permeable surface layer, an absorber and a liquid-impermeable top layer that are stacked sequentially from top to bottom. The liquid-permeable surface layer is generally made of pure cotton non-woven fabric. Cotton non-woven fabrics are obtained from raw cotton fibers after degreasing treatment. Raw cotton fibers themselves are in a non-hydrophilic state, so degreasing treatment is required to become hydrophilic. Pure cotton non-woven fabrics obtained after full degreasing treatment are used as hygienic products. The surface layer will form a capillary diffusion effect on the surface after absorbing liquid. The distribution area of ​​human body discharge liquid on the surf...
