Process for preparing bamboo pulp cotton

Abstract

The invention discloses a process for preparing bamboo pulp cotton, comprising the following steps of preparation of bamboo glue, preparation of a sponge and posttreatment. The process is characterized in that the bamboo glue is prepared by the steps of soaking bamboo fibers in an alkaline liquor, then ageing, yellowing and carrying out post-dissolution; the sponge is prepared by mixing ripened glue and sodium sulfate decahydrate, adding a colorant, evenly stirring, putting into an appointed mold and heating for curing and forming, wherein the ripening ammonium chloride value reaches 7+ / -0.5ml, and the weight of the sodium sulfate decahydrate is 3-5 times of the weight of the glue; and the posttreatment comprises the following steps of: washing the formed sponge 1-3 times to remove most of sodium sulfate decahydrate in the sponge, then carrying out acid-washing, desulfuring and alkali-washing, then washing to be neutral with tap water, and carrying out moisturizing and fungus-resisting treatment to obtain the finished product of the bamboo pulp cotton. The bamboo pulp cotton prepared by adopting the process disclosed by the invention is clean and environment-friendly and has durable antibiosis and bacteriostasis effects.

Description

technical field

[0001] The invention relates to a production process of a sponge product using bamboo fiber as a raw material, in particular to a preparation process of bamboo pulp cotton, and the prepared sponge can be widely used in the cleaning field. Background technique

[0002] Traditional viscose fiber is made of wood fiber and cotton fiber, and after a series of reaction processes, viscose short fiber, long fiber, cellophane and other products are prepared.

[0003] Bamboo fiber is extracted from bamboo. Bamboo is a kind of rapid growth and abundant output. The use of bamboo fiber greatly reduces the need for wood fiber and cotton fiber, and reduces the damage to forest resources. Secondly, because bamboo fiber has special properties, the most prominent The most important thing is its antibacterial and bacteriostatic effect, and most of the antibacterial and bacteriostatic sponges at this stage are achieved by adding bactericidal and antifungal agents, and this type ...
