Non-woven fabric short code and hard cotton problem explanation

The problem of non-woven fabric short code and hard cotton has been a problem that has plagued everyone for a long time. Let us explain the problem of non-woven fabric short code and hard cotton. Thinner non-woven fabrics are more prone to short codes, and everyone in this industry knows why? Because when non-woven fabrics are wound, the finished product becomes larger and larger. At the same winding speed, the line The speed will become larger and larger. The thinner non-woven fabrics tend to be stretched because of the lower tension. Short code problems will occur due to the tension release after the roll.　　 As for the thicker and medium-sized products, the tensile strength of the production is larger, and the stretch is smaller, and it is not easy to cause short code problems. Not only broken code is a common problem, among which hard cotton is also common. The work roll is wrapped around cotton during production. Most of the reasons are that the low oil content of the fiber causes the friction coefficient between the fiber and the card clothing to be abnormal, and the fiber sinks under the card clothing. As a result, the work roll is entangled with cotton, and the fiber wound on the work roll cannot be moved. After the continuous friction and compression between the card clothing and the card clothing, it gradually melts and becomes hard cotton. To eliminate entanglement, the method of lowering the work roll can be used to remove the entanglement on the roller. In addition, it is easy to cause work roll entanglement problems in case of long sleep. The above problems are actually relatively common problems during the production of non-woven fabrics. Everyone needs to understand the cause of the problem and how to solve it. Will produce a good non-woven fabric.
