Problems solved by technology

[0002] During menstruating nights, due to factors such as long sleep time, frequent changes in sleeping positions, and large menstrual blood volume, even if women use lengthened and widened sanitary napkins, menstrual blood often flows smoothly due to factors such as poor fit and insufficient absorption. The buttocks flowed to the back, overflowed and stained the underwear and even the sheets and bedding, which brought great trouble to menstruating women's sleep at night
[0003] Existing sanitary napkins are usually solved by lengthening and widening super-large fan tails in order to prevent rear leakage. The lengthening and widening will inevitably lead to an increase in production costs, and in order to save production costs, companies basically do not add or Add less super absorbent resin (SAP), when the menstrual blood flows to the back end, the sanitary napkin has no much absorption capacity, resulting in postmenstrual blood leakage, which cannot fundamentally solve the postmenstrual bleeding, especially for women with heavy menstrual blood at night question

Abstract

The invention relates to a leakage-proof sanitary towel made of collapse-prevention non-woven fabric containing super-water-absorbent fibers and a manufacturing method. The triple-stepped-type back-leakage-proof night-use sanitary towel sequentially comprises a surface layer, the collapse-prevention non-woven fabric containing the super-water-absorbent fibers, an absorbing core and a PE breathable bottom membrane from top to bottom. The triple-stepped-type back-leakage-proof night-use sanitary towel is characterized in that three pieces of collapse-prevention non-woven fabric containing the super-water-absorbent fibers are compounded to the position below the surface layer of the back end of the interior of the night-use sanitary towel in the mode that the collapse-prevention non-woven fabric is 0-3 cm away from each other in a front-and-back manner; the width of the collapse-prevention non-woven fabric ranges from 1 cm to 5 cm; the thickness of the collapse-prevention non-woven fabric ranges from 0.1 cm to 2.0 cm; the three pieces of the collapse-prevention non-woven fabric are gradually thickened in a stepped manner from front to back; and the collapse-prevention non-woven fabric is formed by compounding the super-water-absorbent fibers and PE / PET composite fibers, so that the elasticity recovery performance is good, the character is stiff and smooth, and collapses are prevented. By means of the structure, the attachment performance is good, and the backwards-leaked menstruation can be collected step by step; menstruation overflowing is prevented through triple-stepped-type protection; it is guaranteed that when a woman large in menstruation amount falls asleep, backward leakage of the menstruation is avoided, overflowing is avoided, and a comfortable and secure sleeping environment is created for the woman in the menstruation period, in particular to the woman large in menstruation amount.
