Problems solved by technology

[0002] Cotton felts in the prior art usually use 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 25mm, which will greatly increase the transportation cost, because the thickness is kept at 25mm, and only a fixed amount can be carried in the unit volume. If the thickness of the cotton felt can be reduced, it will not Affecting the performance of the cotton felt requires a series of research and development processes

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. Those skilled in the art can make modifications to this embodiment without creative contribution as required after reading this specification, but as long as they are within the rights of the present invention All claims are protected by patent law.

[0028] The processing technology of cotton felt is made of 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 blended cotton, which first mixes PET with half of the hollow fiber, and at the same time Half of the hollow fiber and LPET are mixed, and after this is mixed, the two are mixed.

[0030] Put the compacted and entangled mixed cotton into the opener, and simu...

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] Cotton felts in the prior art usually use 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 25mm, which will greatly increase the transportation cost, because the thickness is kept at 25mm, and only a fixed amount can be carried in the unit volume. If the thickness of the cotton felt can be reduced, it will not Affecting the performance of the cotton felt requires a series of research and development processes. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a processing technology for cotton felt, which reduces the thickness of the cotton felt by changing the proportio...
