Problems solved by technology

[0004] In order to make up for the deficiencies of the prior art, and solve the problem that the prior art cannot maximize the adsorption performance of the adsorptive particles contained in the filter cloth when manufacturing the composite filter cloth, at the same time, when preparing the filter cloth, the adsorptive filter powder and The combination of the middle spun cotton is not strong enough, and the problem of delamination is easy to occur. The preparation method of a composite layer non-woven fabric proposed by the present invention

preparation example Construction

[0027] Such as Figure 1 to Figure 4 Shown, the preparation method of a kind of composite layer nonwoven fabric of the present invention, the preparation method of this composite layer nonwoven fabric comprises the following steps:

[0028] S1: Make silk, natural cotton fiber, polypropylene and seaweed fiber sequentially through the opening machine, carding machine and web laying machine to form oriented or randomly arranged fiber webs, and pass the fiber webs into the hydroentanglement machine, and spray them with high-pressure fine water flow processing, so that the fibers are entangled with each other to form an outer layer of non-woven fabric for use; polypropylene is blended with cotton fibers, silk and seaweed fibers, and the outer layer of non-woven fabric formed by spunlace itself has Strong air permeability and hygroscopicity, using it as the outer non-woven fabric can not only play a covering role, but also make the prepared composite non-woven fabric have better air...

Embodiment approach

[0035] As an embodiment of the present invention, the modified tank 15 is located between the first cavity 2 and the second cavity 4, and a rotating groove is provided; the rolling groove is connected with a rolling roller 5 in rotation; the rolling groove The surface of the pressure roller 5 is covered with a rubber layer; when working, when the expanded silk floss sheet passes through multiple first cavities 2 airflow impacts, it continues to move forward, and contacts with the rolling rollers 5 in the rotating groove, so that the expansion The surface of the silk floss sheet is uniformly squeezed, thereby making the internal structure of the expanded silk floss sheet denser, making the fiber filaments have a stronger interception effect on the adsorptive particles, and effectively avoiding the thermal compounding of the adsorbent particles inside the expanded silk sheet after shaking. Dropping occurs before, thereby reducing the performance of the filter cloth produced, and ...

Abstract

The invention belongs to the technical field of polymer composite materials, and particularly relates to a preparation method of a composite layer non-woven fabric, wherein the preparation method comprises a shell, a motor and a hopper; one end of the shell is fixedly connected with a feeding roller through a guide rod; the feeding roller is sleeved with an outer-layer non-woven fabric, a hot-meltnon-woven fabric and an expanded silk floss sheet respectively; symmetrically designed drying grooves are formed in the shell; a fluorescent lamp constant-temperature design is adopted in the dryinggrooves; a modification groove is formed in the shell; the modification groove is used for performing modification treatment on the expanded silk floss sheet; the drying grooves and the modification groove are both positioned at an opening in the upper part of the shell; a sealing cover is hinged to the upper portion of the shell. First cavities are formed in the positions, located on the two sides of the modification groove, of the shell. Adsorptive particles are impacted on the expanded silk floss sheet under the entrainment of airflow, fibers on the surface of the expanded silk floss sheetare impacted and enter the expanded silk floss sheet along gaps among the fibers, and thus the adsorptive particles are evenly distributed in the expanded silk floss sheet.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, in particular to a preparation method of composite layer non-woven fabric. Background technique [0002] Composite non-woven fabric is a new type of packaging material. It can perform multiple composite treatments on non-woven fabrics and other fabrics, such as film coating treatment, hot pressing treatment, glue spray treatment, ultrasonic treatment, etc. Through composite treatment, two layers can be combined. Or three-layer fabrics are combined together to produce products with special functions. Nowadays, composite materials have been widely used in daily life. In the prior art, composite non-woven fabrics are used to prepare filter cloths because the non-woven fabrics themselves do not need to be woven. characteristics, the manufacturing process of the filter cloth prepared by using composite non-woven fabric is simple, and the obtained filter cloth has good elasticity an...
