Abstract
The invention discloses a method for preparing a Chinese medicinal cellulose fiber by a solvent method. The method comprises the following steps of: firstly, mixing and dissolving 3 to 25 weight percent of cellulose, 95 to 75 weight percent of ionic liquid and 0.01 to 0.5 weight percent of Chinese medicinal powder, and defoaming the mixture, spraying the defoamed spinning solution in air to form strands, immerging the strands into the spinning solution, drawing, oiling, bleaching and cutting to obtain the finished fiber. The method adopts the ionic liquid as a solvent, which is easy to recycle and realizes the cleanness and green production of the cellulose fiber; and besides, the produced fiber has the advantages of good performance index, hydroscopicity, good ventilation property and the like of solvent spun cellulose fibers, and remarkable anti-ultraviolet and antibacterial functions.
Description
Technical field
The present invention relates to the chemical fibre preparation field, relate in particular to a kind of production method of functional Lyocell fibre.
Background technology
The cellulose solvent method is because of adopting the technology path of direct dissolving cellulos, whole flow process does not only have chemical reaction, technological process is short, equipment investment and less energy consumption, cleanliness without any pollution, and the fibre property of being produced is good, the added value height, therefore development in recent years is very swift and violent: Lenzing company etc. has formed and has produced 30000 tons production line per year, weaving holding group in Shanghai invests 1.3 hundred million and sets up 1000 tons production line, National Development and Reform Committee's project verification, 30,000 tons of production lines are set up in Baoding Swan Co., Ltd.'s planned investment 1,200,000,000, and the Hongyuan, Fujian is produced 5000 tons of novel solvent method regenerated bamboo fiber production lines per year and gone into operation.
Meanwhile, the breach of China's functional textile product is very big, output is less than 5% of whole textile industry, the functional clothing lining will be the trend of following garment material to development in Hi-Tech, will become the emphasis of international chemical fibre textile industry, give solvent and spin fiber with a functional new direction that becomes the cellulose fibre new product development.
The Chinese medicine calamine is used for the treatment of multiple contact dermatitis skin disorders such as the wet sore of eczema, moltenly spin the Chinese medicine cellulose fibre not only to have a Lyocell fibre soft, hygroscopicity, good permeability, comfortable and easy to wear, advantages such as good luster also have significant uvioresistant and antibacterial functions.
