Description

Sanitary towel softness testing arrangement

Technical Field

The utility model relates to a sanitary towel compliance testing arrangement.

Background

A sanitary napkin, also known as a sanitary towel, is an absorbent material mainly made of cotton-like pulp and a polymeric absorbent for absorbing menstrual blood from the vagina when women have menstrual flow.

The sanitary napkin can be divided into a surface layer, an absorption core and a bottom layer.

The materials of each layer are bonded by hot melt adhesive.

The surface layer is the part directly contacting with the skin, the material is soft, and the surface weave and the indentation can influence the reverse osmosis effect (dryness and comfort) of the sanitary towel.

The PE perforated film surface layer and the cotton surface layer are two most commonly used materials, and due to the microporous design of the PE surface layer, menstrual blood is not easy to permeate back, and a user can feel dry, but the materials are hard, and part of the user can cause anaphylactic reaction; due to the improvement of cotton absorption capacity design and the appearance of punching type and composite type materials, the market share after 2001 is gradually higher than that of the sanitary cotton with the PE surface layer.

The inner layer is mainly made of cotton, non-woven fabric, paper pulp or high molecular polymer and high molecular polymer composite paper formed by the above materials, and is used for absorbing the flowing menstrual blood. The design of side mainly is used for preventing the edge leakage, because can present certain angle with the sanitary-napkin body during the use, more easily with the part of the groin come to the friction, consequently use the sanitary-napkin of the side of soft material to favor by women. The back glue of the sanitary napkin is a waterproof material, can retain menstrual blood in the sanitary napkin, develops the self-adhesive back glue in the 70-80 years, and is convenient for fixing the sanitary napkin on the underpants.

After the sanitary towel is compounded through multiple layers, the softness of the sanitary towel needs to be tested, the sanitary towel with higher softness has better fitting performance, and the use is more comfortable.

Based on the problems, a special sanitary towel softness testing device capable of accurately measuring the softness of a sanitary towel is designed.
