Description
Technical field
The invention belongs to textile technology field, be specifically related to a kind of linen-cotton blending yarn containing exothermal infrared fiber
Preparation method.
Background technology
In textile technology field, yarn is to ensure that the key of textile product quality, scientificlly and effectively selects various with mixed
Yarn and suitably blending rate, be not only related to the cost of product, be more related to the quality of product.Ramie textile industry at present,
More employing flax fiber and other fiber blends prepare linen blend yarn, as by Caulis et Folium Lini and specialty fibers blending, with
While keeping Caulis et Folium Lini advantage, improve the shortcomings such as sodolin is coarse, feel is poor.
Hemp have excellence moisture absorbing and sweat releasing performance, natural antibiotic health care performance, good soft comfortable performance,
Remarkable anti-ultraviolet property, outstanding resistance to elevated temperatures, unique suction ripple absorption property and natural rough style, it is described as
" kings in fiber crops ".But flaxen fiber has certain prodding and itching feeling with cotton, hair phase comparison skin, and fiber is more thick and stiff and length and
Fineness is the most irregular, cause hemp cloth grey cloth rough surface, feel endure with all one's will.Due to hemp macromolecular orientation degree and
Degree of crystallinity is higher, causes its rigidity big, and elastic little, between fiber, cohesive force is poor, and resultant yarn is more difficult, and dye molecule is difficult to enter fibre
Dimension is internal, degree of fixation is low, the problems such as dyeability is poor.
Apocynum fibre is a kind of phloem fiber, and it is positioned at the phloem tissue on Herba Apocyni veneti plant haulm, and fiber is elongated
And glossy, in the loosest fibre bundle, individuals fibers individualism.Herba Apocyni veneti ultimate fibre is a kind of closed at both ends, middle
Having cell, middle part is thick and cellular object that two ends are thin, and cross section is obvious irregular kidney-shaped, and lumen is less, and fiber is longitudinally
Without reversing, surface is with the presence of many vertical lines and has horizontal joint.Fibre fineness is about 0.3tex-0.4tex, and length is close with cotton fiber,
Average length is 20mm-25mm, but difference in length is relatively big, and fiber is pure white, fine quality.
Herba Apocyni veneti is the fine fiber that in bast-fibre, quality is only second to Boehmeria, if with ultimate fibre quality and cotton fiber or
Chemical fibre blending, effect is preferable, and the application of apocynum fibre has been directed to a lot of textile, but in the production of fiber,
Owing to its smooth surface is without curling, cohesive force is little, is easily scattered in textile process, and row yielding is low, and affects yarn quality.By
Can not get well controlling in quality, cause yarn, producing of fabric the biggest difficulty to occur, and can not be guaranteed in quality.
Winter, people slept in bed, were often sent out cool by bedding, easily had a rest bad, drastically influence people
Sleep quality.The most traditional jacquard fabrics based on pure-cotton fabric, the feature such as the most traditional softness, moisture absorption, do not have
Have and absorb the sun and the infrared ray of human body reflection, be allowed to be converted into heat energy, the fabric made can not the function of self-heating, pattern
The most single, lack third dimension.
At present, lack a kind of prepared product and there is the ramie cotton blending yarn containing exothermal infrared fiber of health-care physical therapy function
The preparation method of line.
