1. Common quality problems of diapers and the corresponding causes
According to the random inspection and the testing,
quality problems of diapers mainly focus on three aspects: hygiene indices, permeability and pH values.
The users of
diapers are infants or adults who is incontinent. Their resistance is relatively weak so that
diapers with unqualified hygiene indices may affect the health of users. Hygienic indices of raw materials, environmental hygiene during production and processing, and storage and transportation conditions may all lead to unqualified hygienic indices of
diapers.
Diapers with unqualified permeability can't absorb and fix liquid well, which easily causes users to feel uncomfortable and affects skin health. Permeability is generally related to the properties of raw materials, such as the material used in the surface layer, the diversion layer and the absorption layer of
diapers.
With respect to the pH value, if the value of
diapers is unqualified, it may cause skin irritation or diaper rash. Raw materials, storage and transportation environment may affect the pH value of
diapers.
2. How to improve the quality of diapers?
Enterprises should improve
the quality of diapers from the following three aspects:
First of all, strictly control the quality of raw materials, which plays a decisive role in
the quality of diapers. Only by selecting excellent raw materials can high-quality
diapers be produced.
Secondly, constantly optimize product design. By optimizing the product structure, the product performance can be continuously improved, and the product can meet the needs of consumers. For example, the diaper with suspended core appeared in the market recently. It greatly improved the absorption capacity and rate of the core to the liquid through changing the bonding method between the core and the base film.
Finally, strengthen the control of storage and transportation. The conditions of storage and transportation must be strictly controlled to meet the qualified hygiene index and pH value of
diapers. If the products are placed in a damp or polluted environment, the bacterial quantity or pH value of the products may be unqualified.
