Example Embodiment

[0017] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] Such as figure 1 As shown, this embodiment provides a production process of sound insulation cotton, including the following steps:

[0019] a. Carding process: the hollow polyester staple fiber is unpacked by a bale opening machine, and then processed by a cotton feeding machine and a carding machine to form a hollow polyester cotton roll with a width of 1.8m and a thickness of 4.5cm;

[0020] b. Melt-blown web-forming process: After liquefying solid polypropylene, the polypropylene and hollow polyester cotton rolls are uniformly melt-blown on the surface of the hollow polyester cotton roll at a ratio of 1:7, and the hollow after melt-blown polypropylene is used with a web forming machine. The polyester cotton roll is processed into a net;

[0021] c. Cloth covering process: the solid colloid is liquefied and sprayed evenly on the surface ...

Abstract

The invention provides a production process of soundproof cotton. The production process comprises a cotton combing process, a melt-blowing net forming process, a covering process, an embossing and cutting process and a punching process. According to the production process of the soundproof cotton, polypropylene is melt-blown on a hollow polyester cotton roll to improve the strength of the soundproof cotton and ensure that the soundproof cotton can not be damaged easily during mounting and use, can not be aged easily and is good in weather resistance and long in service life. In the covering process of the production process of the soundproof cotton, a small amount of glue is uniformly sprayed on the surface of the hollow polyester cotton roll at first, then a non-woven fabric covering process is carried out, and a glue is added between the non-woven fabric and the hollow polyester cotton roll to ensure that the produced soundproof cotton is more stable and durable in structure, and the service life of the soundproof cotton is effectively prolonged.

Description

technical field [0001] The invention relates to a production process, in particular to a production process of sound-insulating cotton. Background technique [0002] Hollow polyester staple fibers have good sound insulation performance due to the holes in the fibers, so hollow polyester staple fibers are often used as materials in the production of sound insulation cotton. However, there are still some problems in the use of sound insulation cotton, such as unsatisfactory strength, insufficient light weight, and sound insulation performance to be improved. Therefore, in the production process of sound insulation cotton, the above problems should be improved and solved, and the strength of sound insulation cotton should be improved. On the premise of sound insulation performance, realize the lightweight development of sound insulation cotton. Contents of the invention [0003] The purpose of the present invention is to provide a production process of sound-insulatin...
