Problems solved by technology

[0002] PP needle-punched cotton is made of PP short fiber through needle punching machine opening, carding, laying, and needle punching. It is widely used in the filling of plush toys and household products; PP short fiber can also be used in concrete As a reinforcing material for pouring dams and avoiding concrete cracking; however, it has not yet appeared in the field of composite material production and processing

Embodiment Construction

[0019] A method for producing PP needle-punched cotton, which completes the entire production process through a needle-punching machine, comprising the following steps:

[0020] (1) Preparation of raw materials: use PP staple fibers with a certain crimp of 3-5 pieces / cm, a certain length of 77.95-78.05mm, and a certain linear density of 80.98-81.02dtex;

[0021] (2) Pre-opening: control the motor frequency of the opening equipment to 35HZ;

[0022] (3) Second opening: repeat step (2), control the motor frequency of the opening equipment to 35HZ, further improve the looseness, and make the dispersion more uniform;

[0023] (4) Dispersion: The PP staple fiber after secondary opening is transported to the large cotton box for dispersion through the conveying device, and the motor frequency of the dispersing device is controlled to 30HZ;

[0024] (5) Large cylinder carding into a web: the dispersed PP short fibers are carded and formed through a large cylinder, wherein the freque...

Abstract

The invention relates to production method and application of PP acupuncture cotton. The production method comprises the steps of preparing raw materials; pre-opening; opening for the second time; dispersing; combing into a net through a large cylinder; pulling to pave the net; acupuncturing; coiling. The prepared PP acupuncture cotton can be used as a composite material core; the core has the advantages of being quick in resin flow guide speed, obvious in thickening, high in rigidity after being combined with resin, convenient to subsequent processing, relatively low in cost, and replacing imported core.

Description

technical field [0001] The invention relates to the production and processing field of needle-punched cotton, in particular to a production method and application of PP needle-punched cotton. Background technique [0002] PP needle-punched cotton is made of PP short fiber through needle punching machine opening, carding, laying, and needle punching. It is widely used in the filling of plush toys and household products; PP short fiber can also be used in concrete As a reinforcing material to pour dams and avoid concrete cracking; however, it has not yet appeared in the field of composite material production and processing. Contents of the invention [0003] The object of the present invention is: provide a kind of processing method of novel PP needle-punched cotton in order to solve the above problems, and it should be used as composite material core material. [0004] The technical scheme adopted in the present invention is as follows: [0005] A kind of production metho...
