Specifics for manufacturing insulating needle-punched nonwoven materials from coarse wool

Abstract

The properties of the finished insulating needle-punched non-woven material depend on the nature of component fiber, the manner in which the fibers are arranged in the structure, and the degree of consolidation. A proper understanding of the role of different parameters in the manufacture of nonwovens is important in mat design and operation. Since many factors can affect the insulation properties. This paper is intended to study and analyze the peculiarities of the technology of needle-punched nonwoven. The process of creating nonwoven mats from 100% coarse sheep wool was studied, as well as the principles of operation of the machines included in the production line, the specifics of the needle used to create mats, and the method of needle setting.
