How to improve the qualified rate of needle punched non-woven fabric production

The so-called pass rate is mainly based on the weight, thickness, and tension of the needle-punched non-woven fabric. There are many reasons for the improper quality of the needle-punched non-woven fabric. After years of experience in the production of Zhicheng Fiber, the following is a brief summary 3 reasons:


1. The grammage weight can directly affect the weight of the customer's product. In the process of laying the net, the level is uneven and the two ends are not connected accurately.


2. Thickness and uneven thickness are also caused by uneven fiber cotton spreading during carding and web laying. Insufficient technical experience and insufficient precision equipment are all reasons.


3. The pulling force, the strength of the pulling force, is mainly determined by the number of times of acupuncture, the more the number, the stronger the pulling force. Zhicheng Fiber can set different tensile strengths according to customer requirements. Zhicheng Fiber has 4 needle-punched cottons, each of which can reach 1,200 times per minute.


In order to improve the pass rate of needle punched non-woven fabrics, our Zhicheng Fiber has specially strengthened the training work for the personnel of the production department, and improved the requirements for quality control inspection, making the work more standardized and process-oriented, and avoiding the weight and weight caused by human factors. The thickness and tension are unqualified.
