Problems solved by technology

[0002] The cotton felt in the prior art usually adopts about 70% PET material and about 30% LPET material, and the finished product is obtained after cotton blending, cotton blending, opening, carding, cotton laying, heat drying, and cutting. The thickness of the cotton felt produced in this way is usually about 28±3mm, which will greatly increase the transportation cost, because the thickness is kept at 28±3mm, and only a fixed amount can be carried in the unit volume. If the thickness of the cotton felt can be reduced At the same time, it will not affect the performance of the cotton felt, it needs to go through a series of research and development process

Embodiment Construction

[0026] The present invention will be described in further detail below.

[0027] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contribution as needed, but as long as the rights of the present invention All requirements are protected by patent law.

[0028] The processing technology of cotton felt uses high-melting-point PET, hollow fiber with good bulkiness and low-melting-point LPET.

[0029] The main process flow is as follows: 20%-40% PET, 30%-50% hollow fiber and 30% LPET are mixed in proportion to form a cotton blend. First, the PET is mixed with half of the hollow fiber, and the other Half of the hollow fiber is mixed with LPET, and then the two are mixed after mixing.

[0030] The compressed and entangled cotton blend is added to the opener, and the two sides are opened simultaneou...

Abstract

The invention discloses a processing technology of cotton felt. The processing technology of the cotton felt comprises the following steps: (1), cotton blending, wherein the ratio of PET to hollow fiber to LPET is 30%:40%:30%; (2), cotton mixing; (3), opening; (4), carding; (5), cotton laying; (6), hot baking, wherein the temperature is maintained at 220-250 DEG C, and the fan is controlled at 1200 + / - 200 rev / min; (7), rolling, wherein the thickness of the cotton felt is controlled at 10 + / - 2mm; (8), fan cooling: normal temperature; and (9), cutting and shipping. The cotton felt produced bythe processing technology of the cotton felt provided by the invention is small in volume and convenient to transport, and can be reused after being restored to the original state by heating.

Description

Technical field [0001] The invention relates to a processing technology of cotton felt. Background technique [0002] The cotton felt in the prior art usually uses about 70% of the PET material and about 30% of the LPET material. The finished product is obtained after blending, blending, opening, carding, laying, heat drying, and cutting. The thickness of the cotton felt produced in this way is usually about 28±3mm, which will lead to a great increase in transportation costs. Because the thickness is maintained at 28±3mm, only a fixed amount can be carried in the unit volume. If the thickness of the cotton felt can be reduced At the same time, the performance of the cotton felt will not be affected, and a series of research and development processes are required. Summary of the invention [0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a cotton felt processing technology, by changing the ratio of the cotton felt and increas...
