Apocynum industrialized fiber production machining method and apocynum fiber

Abstract

The invention relates to an apocynum industrialized fiber production machining method and apocynum fiber. The method orderly comprises the following steps of: separating peel core from apocynum peel-previously removing impurities-refining enzyme-water washing, fiber beating, dehydrating and fluffing-boiling and refining with ammonium salt-fiber beating and dehydrating, fluffing-oxidation bleaching-dehydrating and fluffing-oil feeding-dehydrating and fluffing-drying-refining dried flax. The refined dried fiber of the apocynum produced by the method has residual gum content being 2-5%, fiber average length being more than 30mm, fiber breaking length being more than 40 kilometers, and average fibrecount being more than 2200 counts. A cotton stalk separating machine successfully mechanically separates the peel core, to guarantee the industrialized production of the apocynum; and the enzyme-ammonium salt unite fiber production technology obviously heightens the rate of the certified products of the refined and dried flax of the apocynum and greatly improves the inner quality of the refined and dried flax, to realize the industrialization of the apocynum fiber, save energy in the process of production, and is environment-friendly.

Description

technical field [0001] The invention relates to a bast fiber and its industrial chemical fiber processing method, in particular to an apocynum fiber and its industrial chemical fiber processing method. Background technique [0002] Apocynum, also known as big-leaf white hemp, is mainly distributed around the Tarim Basin and the Robe Plain. There are 1.295 million mu of wild apocynum in Yuli County, Xinjiang alone, and the contiguous area can reach 400,000-500,000 mu. Apocynum is a perennial herb that can live for twenty or thirty years. It grows in saline deserts and arid regions with great temperature differences. Its root system is very developed, and its underground stems can reach up to thirty meters. The apocynum fiber extracted from the phloem is the best textile material and has the laudatory title of "king of wild fibers". It integrates the luster of silk, the softness of cotton, and the crispness of linen. It has good moisture absorption, fast heat dissipation, a...

Problems solved by technology

The second big problem is the degumming method of apocynum. In the prior art, the used chemical degumming method of ramie degumming is generally adopted. This method has serious environmental pollution, and has damaged the natural style and health care effect of apocynum fiber. Similarly, for single fiber spinning, it is required that the glue should be basically removed, and the residual glue rate of ramie fine-dried hemp should be controlled at about 2%. There is no standard for what level

[0009] Therefore, the degumming of apocynum is more difficult than ramie degumming, and the chemical degumming method of ramie cannot be used. Even if harsher process conditions are used on this basis, it will inevitably cause great damage to the fibers and cause more serious environmental pollution.

[0010] The genuine product rate of the dry hemp of apocynum obtained in the prior art is not high, and the technical indicators such as the length of the dry hemp fiber, strength, cohesion strength, elongation at break, carding rate, wear resistance, bending resistance, and fatigue resistance are difficult to reach the conventional level , the degumming rate is less than 40%, the fiber surface is smooth, and the cohesion is poor, which is not conducive to spinning

[0011] Because the technical problem of apocynum degumming has not been solved, the utilization of apocynum fiber is still in the experimental stage or sporadic workshop-style intermittent production level, and industrialized large-scale production has not been realized.
