Embodiment Construction

[0024] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0025] like Figure 1-3 Shown, a kind of preparation method of equal density cotton comprises the following steps:

[0026] Cotton material production steps: the raw material is firstly opened by the opening device, carded by the carding machine, and then entered into the flat laying machine for flat laying, and then enters the oven for drying after cutting, and then is discharged through the outlet of the oven. Cotton material is formed; wherein, the raw material includes polyester chemical fiber, fiber and low-melting cotton; the opening device includes a pre-opener and a main feeder, and specifically, the raw material is first pre-opened by a pre-o...

Abstract

The invention discloses an isopycnic cotton preparation method and isopycnic cotton. The isopycnic cotton preparation method comprises the following steps of a cotton making step, wherein raw materials are subjected to opening through an opening device and subjected to carding through a carding machine, then enter a tiling machine for tiling, enter a drying box for dying after being cut, and thenare discharged through a discharge hole of the drying box to form cotton; a blank making step, wherein, the cotton is preheated by means of a preheating mold to form a blank, the preheating mold comprises a preheating upper mold body and a preheating lower mold body, in the blank making step, the cotton is put on the preheating lower mold body of the preheating mold, the cotton is supplemented with leftover materials, and the cotton is preheated through preheating mold clamping; a finalizing step, wherein the blank is cooled and finalized, and the isopycnic cotton is obtained. According to theisopycnic cotton preparation method, the method is simple and convenient, and the density of the obtained isopycnic cotton can be consistent.

Description

technical field [0001] The invention relates to a preparation method of isodensity cotton and isodensity cotton. Background technique [0002] At present, it is often necessary to use cotton as a layer of interlayer in the interior of the car, so that the layer of cotton can play the role of cushioning and sound insulation. However, the existing cotton preparation method is relatively complicated, and the steps are relatively loaded down with trivial details, and the density of the produced cotton often appears to be different, so it is far from meeting the needs of the industry. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, one of the objectives of the present invention is to provide a method for preparing isodensity cotton, which is relatively simple and convenient, and can make the density of the prepared isodensity cotton consistent. [0004] The second object of the present invention is to provide a kind of equal-density c...
