Airflow air laid fiber cotton preparing process and manufactured fibre cotton

Abstract

The invention discloses a method for preparing air-laying cellucotton and cellucotton produced by the method. Taking low melting point fibers and other fibers as raw material, the cellucotton is produced by rough shape cutting, coarse opening, fine opening, air laying, hot binding and parting cut packaging, wherein the air laying is as follows: the loose fibers which are distributed evenly in a cotton box after fully mixed by the fine opening are further mixed by airflow and delivered by pressurized airflow to between the net forming curtain and the net forming roller to be formed into a required retiform structure. The preparing process has wide range of material selection, is suitable for not only all the raw materials adopted in the prior process, but also the plant fiber widely existing in the natural world which are not used in the prior art such as couch grass, reed, cornstock, straw and bagasse as raw materials, and the waste materials such as wood wool, crushed sponge and wool manufacturing crushed aggregates to reuse and regenerate; in addition, the preparing process has high production efficiency and low energy consumption, and produces the cellucotton with great improvement in the performance, thereby being applied to wider fields.

Description

Technical field [0001] The present invention relates to a kind of air-laid fiber cotton preparation process, more specifically, the present invention relates to a kind of method that uses low-melting point fiber (hot-melt fiber) and other fiber to mix heat treatment to prepare fiber cotton, the present invention also relates to using this process Fiber cotton produced. The preparation process has a wide range of material selection, not only applicable to all raw materials used in existing processes, but also raw materials that cannot be used in existing technologies, such as: thatch, reed, wheat straw, straw, hemp, jute, flax, bananas that have been dehydrated and removed Trees, corn stalks, bagasse, and other plant fibers that exist widely in nature, as well as waste materials such as wood shavings, broken sponges, and wool textile scraps, can replace the existing large-scale synthesis of by-products from the petrochemical industry and coking industry. The fiber has high pro...

Problems solved by technology

[0008] The present invention aims at the defect of single material selection range caused by the lack of fiber web (type) in the existing hot-melt cotton production process, and adopts an air-laid process, which not only has a wide selection of materials, but also improves the fiber web structure in an all-round way, and can also be used according to needs. Produce heat-melt cotton with controllable thickness and density to improve product quality
