Process for producing flame retardant environment-friendly blend felt

Abstract

The invention discloses a process for producing a flame retardant environment-friendly blend felt, and belongs to the technical field of blend felt production. The process includes the following steps: material feeding, cotton plucking, needling I, flame retardant agent solution soaking, solution extrusion, drying I, baking, washing, drying II, needling II, and blend felt forming. The blend felt produced by the technical scheme is good in sound absorption effect, is excellent in mechanical property, is high in environment protection performance during production, and will not cause allergy ofa human body during use and assembly.

Description

technical field

[0001] The invention relates to the technical field of mixed felt production, and more specifically relates to a production process of a flame-retardant and environment-friendly mixed felt. Background technique

[0002] In recent years, my country's science and technology have made great progress, and the national economy has maintained sustained, rapid and stable development. Although people's living standards have improved, noise has become a major environmental pollution. How to eliminate or weaken it now? The problem of noise environment has been paid more and more attention by people.
