Embodiment Construction

[0020] The following descriptions are only preferred embodiments of the present invention, and therefore do not limit the protection scope of the present invention.

[0021] The materials used in the present invention are: aromatic polyamide fiber (commonly used: aramid fiber 1414, aramid fiber 1313, aramid fiber 1212), PBO fiber-poly-paraphenylene benzobisoxazole fiber, glass fiber, pre-oxidized silk, Cotton, linen, polyester.

[0022] The production process of the present invention: the above fibers are mixed according to a certain ratio or used alone, and the yarn is spun into a cloth by using the spinning and threading technology and machinery to obtain the basic cloth 10 used for manufacturing high temperature resistant felt products. Then utilize carding machine to mix above fiber according to a certain ratio or use alone, its fiber is carded into fiber web 20; Then, utilize needle-punching machine and punching needle, fiber web 20 is needle-punched to the surface of bas...

Abstract

The invention discloses a high temperature resistant carded felt and manufacturing method thereof, wherein, the high temperature resistant carded felt is composed of a basal layer, and a working layer which is formed by needling and combining multiple layer of base cloth fabric nets, the base cloth fabric net includes base cloth, and the surface of the base cloth is needled with a fabric net. The manufacturing method of the high temperature resistant carded felt includes the following steps: 1 manufacturing base cloth; 2 manufacturing a fabric net; 3 needling the fabric net onto the surface of the base cloth using needling mechanical or felting needle, to form a base cloth fabric net; 4 integrally compounding the base cloth fabric net with a ring shaped nonwoven needling technique, selecting a plurality of layers of base cloth fabric net according to the required thickness of the carded felt to complete the needling and combining molding on the basal layer; 5 using the mechanism and mold to manufacture the base cloth fabric net carded felt formed by needling and combining into the high temperature resistant carded felt. The inventive high temperature resistant carded felt has advantages of good antifriction property, low cost and environment protection.

Description

Technical field: [0001] The invention relates to a high-temperature-resistant felt laid on a cooling bed carrying aluminum profiles and in direct contact with the aluminum profiles. In addition, the invention also relates to a manufacturing method of the high-temperature-resistant felt. Background technique: [0002] After the aluminum profile is extruded from the extrusion machine, it needs to be supported by a cooling table (hereinafter referred to as the cooling table) to realize its cooling, transmission and cutting process. At present, the loads directly in contact with the aluminum profiles on the cooling bed are mostly made of high temperature resistant, wear-resistant and soft special fibers (mainly used: aramid 1414, aramid 1313, aramid 1212), PBO fiber-polyphenylene Benzobisoxazole fiber, glass fiber, pre-oxidized yarn, polyester fiber (polyester)) are made into "high temperature resistant felt", and "high temperature resistant felt" has the following forms: roller...
