Non-woven fabric manufacturers teach you the soft operation of PP non-woven fabrics

In the processing of PP non-woven fabrics, due to the influence of chemical adhesives, additives or low-temperature drying, it will trigger rough and stiff hand feelings, which limits the operation of non-woven fabrics on certain scales. Many sanitary and protective non-woven products, such as sanitary napkin fabrics and all kinds of clean sassafras wipes, require PP non-woven fabrics to have good flexibility, so it is necessary to perform soft cleaning of non-woven sanitary materials, and weave net machinery that is often operated. And chemical preparation.





Mechanical kneading and soft liquidation


If the mechanical kneading and soft liquidation master kneads or shortens the nonwoven fabric through the process, the rigidity of the non-woven fabric is reduced to achieve the soft policy. There are two important mechanical processing systems for this type of soft wheel liquidation, namely the Krapac method and the Mike method. Rasfa.


1. Krapac Method


The Krapac method was first operated on papermaking properties, and then transplanted into wet-laid nonwovens, which was pre-shrinked and liquidated after mimicking the Sanfrai machine. In the following figure, after processing, the non-woven fabric can obtain excellent flexibility and improve the feel. The liquidation of the law depends on the thickness, elasticity, fiber characteristics, pressure, fiber network structure, and thermal and humid conditions of the rubber belt.


2. Mike Rex's method


The Mike Rex method is very strong in squeezing and dyeing pp non-woven fabrics. Therefore, the non-woven fabrics are roughly creped. The delay of the non-woven fabrics is increased. The unit area component and the approximate product are increased. Compared with the Krapac method, this weaving better improves the flexibility of the non-woven fabric. The crepe effect of the Mike Rex method can be evaluated by measuring the increase in cell area or the elongation of the non-woven fabric through the process optical technique. Therefore, the settlement of the law largely depends on the size of the crepe area and the input and output speed of pp non-woven fabrics.


As an important non-woven supplier in the country, Huaqiang non-woven fabric manufacturers currently produce pp non-woven fabrics, sms non-woven fabrics, medical non-woven fabrics, etc.
