Problems solved by technology

[0010] With the promotion of the application range of non-woven fabrics, it is required to increase the unit grammage of non-woven fabrics. For the requirements of grammage specifications, the existing production process is mainly completed by the laying process by adjusting the number of layers of the laying net. However, with the The unit weight specification is increased to more than 120 grams. When the net laying process needs to be stacked to more than 8 layers, this greatly reduces the production speed of the net laying process, thereby reducing the production capacity of the entire production line
[0011] In addition, since natural cotton fibers contain a large amount of cottonseed hulls, it is difficult to remove them in the current conventional nonwoven production process, and a large amount of alkali and bleaching agent will be wasted in the subsequent de-bleaching process to process cottonseed hulls, not only Not environmentally friendly, but also greatly increased production costs
At the same time, due to the characteristics of natural cotton fiber itself, there are many entanglements between cotton fibers and cotton fibers. In the conventional production process, cotton fiber bundles are difficult to be carded into a single fiber state. If they cannot be carded into a single fiber state, The cotton fiber web output from the carding process is prone to unevenness, which eventually leads to unevenness in the nonwoven material produced

Embodiment 1

[0131] Please refer to image 3 , the present embodiment provides a kind of manufacturing equipment of cotton fiber web, comprises cotton picking machine 301, weight separator 302, cotton condenser 303, cotton opener 304, cotton mixing machine 305, cleaning machine 306, carding machine 307, cotton blending machine 308, air fiber separator 309, cotton opener 310, carding machine 311, net laying machine 312.

[0132] The cotton catching machine 301 is used to grab the pure cotton raw materials that meet the specifications and send them to the lower-level equipment for processing. Medium and long fibers under 76mm. It should be understood that the pure cotton raw materials referred to in the embodiments of the present application refer to raw materials in which most of the raw materials are cotton.

[0133] The heavy object separator 302 is arranged downstream of the plucking machine 301 and is used for separating and removing the heavy objects mixed in the pure cotton raw mate...

Embodiment 2

[0146] Please refer to Figure 4 , present embodiment provides a kind of manufacturing method of cotton fiber web, comprising:

[0147] Step 401: Grab pure cotton raw materials that meet the specifications and send them to lower-level equipment for processing. In this embodiment, a reciprocating cotton grabbing machine is used to grab pure cotton raw materials, which is suitable for grabbing various grades of raw cotton, cotton-type chemical fibers, and cotton fibers below 76 mm. In other embodiments, other plucking machines can also be used for medium and long fibers.

Abstract

The invention relates to a manufacturing device of a cotton fiber net. The device comprises a cotton grasper, a weight separator, a condenser, openers, mixers, a cleaner, combers, a gas-fiber separator and a lapping machine. The manufacturing method of the cotton fiber net comprises cotton grasping; weight separation; condensation; opening; mixing; cleaning; combing; mixing; gas-fiber separation; opening; combing and paving. A manufacturing device of a multilayer non-woven material comprises the manufacturing device of the cotton fiber net. The manufacturing method of the multilayer non-woven material comprises the manufacturing method of the cotton fiber net. According to the manufacturing methods and the manufacturing devices of the cotton fiber net and the multilayer non-woven material provided by the invention, cottonseed hulls in the pure cotton material can be effectively removed through a cottonseed hull removing process, so that the subsequent production process is not affected. In addition, a combing process is further added to further comb the pure cotton material to obtain uniform cotton fiber nets, therefore, uniform non-woven material can be obtained.

Description

technical field [0001] The present application relates to the field of nonwoven fabric manufacturing, in particular to a method and equipment for manufacturing cotton fiber webs and multilayer composite nonwoven materials. Background technique [0002] The usual production of cotton spunlace nonwovens adopts the following process: [0003] Material preparation: The raw material of natural, unskimmed and unbleached cotton is prepared and ready to use. [0004] Cotton Cleaning: Clean up the pure cotton raw materials. [0005] Carding: Comb the small cotton bundles into a single fiber state with the help of needle surface movement, further remove impurities and unusable short fibers, and make the fibers parallel and straight. [0006] Laying: According to the requirements of product weight specifications, the cotton web formed by preliminary carding is laid directly or cross-laid according to the direction of cotton fibers to form a multi-layer overlapping cotton web to meet ...
