Description
Technical field
The present invention relates to that a kind of anhydrous Lithium chloride/dimethylacetamide solvent system dissolves after Semen livistonae chinensis leaf fibre element is wet
Method spinning technique, belongs to plant regeneration fibre technology field, particularly one and is applicable to prepare Semen livistonae chinensis leaf fibre element regenerated fiber
Wet spinning technology.
Background technology
In textile industry, tModified Cellulose Fibers is owing to source resource is abundant, environmental friendliness, goods take the spies such as comfortable
Property is constantly subjected to the attention of people.Although its consumption proportion is not as synthetic fibers in recent years, but the most withered due to coal and oil
Exhausting, serious " white pollution " that the non-degradable of synthetic fibers products waste causes in addition is day by day serious, is ploughed simultaneously
The restriction of area, protofibre yield also receives certain restriction, and the demand of fiber is constantly increasing, although weaving
Industry is changed to promoting added value direction by production scale expanding, but still needs to maintain a number of growth to meet state
Inside and outside demand.In the coming years, the demand of fiber will have growth by a relatively large margin, and this makes renewable fibre resources
Exploitation is particularly important, its be possible not only to increase fibre resources source, decrease simultaneously natural resources is taken and
Dependence to non-renewable resources.People are made sight to have been turned to the regeneration with the characteristic such as renewable, green, degradable fine
Dimension.
Semen livistonae chinensis leaf, as the raw material of tModified Cellulose Fibers, south China most area has distribution, especially in river
Door is local more, and cultivation technique is fairly simple.Semen livistonae chinensis leaf aboundresources but the most not by comprehensive development and utilization, big portion
Office is in the state run its course, and this also result in the waste of certain resource.Along with people are to healthy, the day of environmental protection based article
Benefit is pursued, the effective development and utilization of Semen livistonae chinensis leaf, will bring certain economic and social benefit for locality.
Semen livistonae chinensis leaf fibre element regenerated fiber meets modern and produces and the demand of life, but in life, this based article is also
Not finding, the document relevant to the technique of preparation Semen livistonae chinensis leaf fibre element regenerated fiber also has no report.The present invention is to continue from Pu
Certain herbaceous plants with big flowers leaf extracts method (Publication No. CN105019288A) and the dissolving method (Publication No. of Semen livistonae chinensis cellulose of cellulose
CN105017540A), after two inventions, the invention of the spinning technique of regenerated fiber is prepared by Semen livistonae chinensis leaf fibre element.Therefore, Semen livistonae chinensis leaf
The regeneration spinning technique of cellulose is the key issue that the present invention needs to solve.
