Embodiment 1

[0040] The production process of a kind of flame-retardant environment-friendly mixed felt of the present embodiment, its steps are as follows:

[0041] Step 1. Loading: Select polyester staple fibers with a thickness of 5-15D and a length of 30-100mm, and non-woven fibers with a thickness of 6-15D and a length of 50-70mm, and perform feeding and pre-opening respectively;

[0042] Step 2, catching cotton: mix the above-mentioned polyester staple fiber and non-woven fiber, after opening, use a carding machine to evenly card the mixture of polyester staple fiber and non-woven fiber after opening, and then pass the above-mentioned mixture through a web-laying machine Intricate laying to form a fiber web;

[0043]Step 3, Acupuncture I: Arrange the fiber nets in Step 2 together and needling to form the primary mixed felt. Acupuncture I is divided into:

[0044] (1) Upper acupuncture: acupuncture frequency is 25~35HZ, acupuncture density is 300~370 needles / cm 2 , the acupuncture d...

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. [0003] The noise of the compressor is the main noise source of the outdoor unit of the air conditioner (especially the small and medium models), and the noise level directly determines the noise value and sound quality of the air conditioner. At present, compressor sound insulation cotton is widely used in the industry to wrap the compressor, so as to attenuate the noise ...
