preparation example Construction

[0016] Preparation of viscose solution: adopt existing technology, use cellulose pulp as raw material, alkalization, pulverization, yellowing, each physical and chemical process of primary dissolution, has made the dilute alkali solution of cellulose xanthate sodium, title Viscose solution, the viscose solution is sent to the spinning process after being filtered, dissolved, filtered, matured, defoamed and other processes. The main indicators of the viscose solution: the weight ratio content of methyl fiber is 8.6-9.2%, the weight ratio content of alkali is 5.3-5.7%, the viscosity is 26-36 seconds, and the maturity is 8-12ml.

[0017] Preparation of bamboo charcoal micropowder emulsion: add dispersant in deionized water in advance, and described dispersant can be selected fatty amine polyoxyethylene ether or polyoxyethylene ether etc., and its weight ratio consumption is no more than 5% of bamboo charcoal micropowder. Bamboo charcoal micropowder is bamboo charcoal obtained by ...

Embodiment 1

[0019] Embodiment 1: the manufacture method of 1.67 * 38dtex * mm bamboo charcoal viscose fiber:

[0020] Preparation of viscose solution: using pulp as raw material, through the physical and chemical processes of alkalization, crushing, yellowing, and initial dissolution, a dilute alkali solution of sodium cellulose xanthate is prepared, and the viscose solution is then dissolved, Filtration, aging, defoaming and other processes are sent to the spinning process. The main indicators of the viscose solution are: 8.8% by weight of methyl cellulose, 5.6% by weight of alkali, a viscosity of 30 seconds, a degree of ripening of 11ml, and a temperature of a ripening chamber of 18°C.

[0021] Preparation of bamboo charcoal micropowder emulsion: Pre-add dispersant in deionized water, the amount of which is 2% of the bamboo charcoal micropowder, turn on the dispersing emulsifier for circulation, then add bamboo vinegar and bamboo charcoal micropowder until the bamboo charcoal micropowde...

Abstract

The invention discloses a bamboo charcoal viscose and preparing method, wherein the bamboo charcoal viscose consists of bamboo charcoal micro powder and bamboo vinegar liquid. The method consists of preparing rubber process and spinning process, wherein it is characterized by the following: preparing viscose solution and bamboo charcoal powder emulsion; adding in disperser and bamboo charcoal powder emulsion in deionized water; mixing up to get bamboo charcoal micro powder emulsion; mixing up viscose solution and bamboo charcoal micro powder emulsion; sending to spinning machine to prepare fiber.

Description

technical field [0001] The invention relates to a spinning technology, in particular to a bamboo charcoal viscose fiber and a manufacturing method thereof. Background technique [0002] In the prior art, bamboo charcoal viscose fiber is a functional textile fiber. In the patent application number 200310110113.9, bamboo charcoal viscose fiber has added bamboo charcoal micropowder in the viscose, and the viscose has been made viscose by adding the powder. Fiber has functions such as absorbing odor. In the preparation method, the bamboo charcoal micropowder is first made into a water-emulsion slurry, and then the water-emulsion slurry is added during the dissolving process of preparing the viscose, and then the viscose solution with the water-emulsion slurry is filtered three times. After filtering with two layers of poplin cloth for the fourth time, spinning is carried out on a staple spinning machine, and finally the fibers spun are washed to obtain ...
