Problems solved by technology

[0002] At present, sound insulation, shockproof, and heat insulation materials for automotive interiors are made of waste wool and phenolic resin, and are made of non-woven air-laid nets. Because this material contains formaldehyde, it will cause harm to the drivers and passengers in the car. harm
Moreover, because phenolic resin is a thermosetting plastic, the composite felt of waste hair and phenolic resin cannot be recycled and reused.

Embodiment 1

[0014] As shown in Fig. 1 and Fig. 2, it is a composite felt made of waste wool, waste terylene and composite fibers and a schematic diagram of the process structure. It is characterized in that: the method is:

[0015] Step 1. Mix 70% waste cotton fibers recovered by textile mills and regenerated fibers 1 of waste textiles thereof, 15% recycled polyester 2, and 15% ES fibers 3 containing polyethylene on the outside by weight percentage;

[0016] Step 2. Utilize the mature process of opening, carding, web laying, acupuncture, and winding to prepare the surface density of 50 g / m 2 composite felt.

Embodiment 2

[0018] Step 1. Mix 40% waste cotton fibers recovered by textile mills and regenerated fibers 1 of waste textiles, 30% recycled polyester 2, and 30% ES fibers 3 containing polyethylene on the outside by weight percentage;

[0019] Step 2. Use the mature process of opening, carding, laying, acupuncture, and winding to prepare an area density of 350 g / m 2 composite felt.

Embodiment 3

[0021] Step 1. Mix 20% waste cotton fibers recovered by textile mills and regenerated fibers 1 of waste textiles thereof, 40% recycled polyester 2, and 40% ES fibers 3 containing polyethylene on the outside by weight percentage;

[0022] Step 2. Use the mature process of opening, carding, laying, acupuncture, and winding to prepare an area density of 500 g / m 2 composite felt.

[0023] The car sound insulation, shockproof and heat insulation materials made of this material have the advantages of environmental protection, odorless and recyclable.

Abstract

The invention relates to a compound felt produced by waste hair, waste nylon and compound fiber, characterized in that it is needled by waste hair, waste nylon and compound fiber. The method is that 10%-80% waste hair by wt, 10%-50% waste nylon by wt and 10%-40% compound fiber by wt are mixed; compound felt with the density of 50g / m 2-500g / m2 is produced by the non-woven technology with loosening, combing, meshing, needling and winding. The invention can take place of sound insulation, heat insulation, anti shock material compounded by waste hair and phenol resin in automobile. The felt compounded by waste hair, waste nylon and compound fiber by mature technology in the invention does not contain formol and odor and can recycle so that the pollution problem to drivers in automobile is solved.

Description

technical field [0001] The invention relates to a composite felt made of waste wool, waste polyester and composite fibers, which can be used for automobile interior materials and belongs to the technical field of automobile interior materials. Background technique [0002] At present, sound insulation, shockproof, and heat insulation materials for automotive interiors are made of waste wool and phenolic resin, and are made of non-woven air-laid nets. Because this material contains formaldehyde, it will cause harm to the drivers and passengers in the car. harm. And, because phenolic resin is a thermosetting plastic, so waste hair and phenolic resin composite felt cannot be recycled. Contents of the invention [0003] The purpose of the present invention is to provide an environmentally friendly, odorless and recyclable composite felt made of waste wool, waste polyester and composite fibers. [0004] In order to achieve the above object, the technical solution of the prese...
