Preparation method of instant-absorption sanitary towel with groove-cut absorber

Abstract

The invention relates to the technical field of sanitary towels, in particular to a preparation method of an instant-absorption sanitary towel with a groove-cut absorber. The preparation method comprises the steps of feeding of composite paper, groove cutting of the composite paper, coating of a core body, bonding of a bottom film, bonding of a surface layer, packaging and the like.According to the invention, the preparation process of the composite absorber is improved, a special knife roller is creatively adopted, and a plurality of strip-shaped flow guide groove holes which are arranged according to a specific rule are cut on the composite paper by a groove cutter on the knife roller, so that a longitudinal conduction path for rapid permeation and diffusion of menstrual blood is regularly formed in the length direction of the composite absorber; and a permeability experiment test proves that under the condition of the same menstrual blood absorption amount, the instant absorption time and the multiple absorption time of the composite absorber are shortened, the longitudinal diffusion length of menstrual blood is prolonged, and the utilization rate of the whole composite absorber is remarkably increased, so as to solve the defects that an existing ultrathin sanitary towel is prone to deformation, breakage, rigidity, clustering and the like and improve the comfort level of a user.

Description

Technical field [0001] The present invention relates to the field of sanitary napkins, and more particularly to the preparation method of transient sanitary napkins of absorbent grooves. Background technique [0002] Contemporary consumers are increasingly pursuing unusual experience, making existing sanitary napkins products more thin. However, the thinner of the product means that the higher the density, the loss of voids, and stores a certain viscosity of the vapor, resulting in a decrease in the absorption capacity of the product, affecting the sense of use. In particular, the most intermediate core absorbent in the sanitary napkin is basically flat straight, and the entire absorption is thin but the density is high, which seriously affects the instantaneous absorption and multiple absorption effects of blood-blood (and mixed secretions in blood). The time of liquid blotting, so that the blood transfer distance having a certain viscosity is very limited, so that most of the b...
