Professional analysis of needle punched non-woven fabric process

Professional analysis of needle-punched non-woven fabric technology-what is the difference between needle-punched fabrics The needle-punching process is very flexible and changeable. Sometimes only one needle punching machine can produce needle punched non-woven fabrics. However, in most cases, in order to improve production efficiency, meet product quality requirements and some special requirements, it is necessary to arrange some needling machines and related equipment into a process in a certain order. There are two basic modes of process flow. One way is to connect the main acupuncture and pre-acupuncture to the assembly line, and the fiber web before acupuncture can be directly fed into the main acupuncture. This arrangement is conducive to continuous production, can improve production efficiency and reduce labor intensity. The other method is discontinuous, in which the pre-needling and main needling are installed separately, the needled fiber web is wound first, and then transported to the main needling machine, unrolled and sent to the main needling machine. If there are more than two main needling machines, the main and main needling machines can be arranged on the production line. The discontinuous arrangement should be a good, easy to change variety, for example, in order to improve the uniformity of the product, two layers of pre-punctured fiber web can be fed into the main needle machine at the same time. In the design, how to arrange the process should be analyzed in detail and cannot be generalized. The following factors are usually considered. (1) Product performance and appearance requirements. (2) The automation capability and degree of the needle punching machine. (3) Site conditions. (4) The quality and management level of workers.
