A kind of preparation method of bamboo charcoal fiber blended yarn

Abstract

The invention relates to the technical field of chemical fibers, in particular to a preparation method of bamboo charcoal fiber blended yarns. The method comprises the following steps: (1)preparing bamboo charcoal fibers and viscose fibers into a mixed pre-drawing card silver; (2) pre-drawing the mixed pre-drawing card silver to obtain pre-drawing silver; (3) preparing viscose fiber mono-fiber yarn into viscose card silver; (4) matching the pre-drawing silver and the viscose card silver, and then performing the primary drawing; (5) uniformly mixing the primarily-drawn silver by virtue of secondary drawing and final drawing to obtain a finally-drawn silver; (6) performing coarse-yarn molding for the finally-drawn silver; (7) performing fine yarn molding by adopting compact siro-spinning; and (8) finally forming yarns by adopting an automatic winding machine, removing yarn faults, and bundling. The method is few in yarn forming neps, relatively few in twitty yarns and less in yarn hairness, the difficulty for blending different bamboo charcoal fibers of different specifications is solved, the applicability to the temperature and humidity is greatly improved, and the problems such as roll sticking, net breaking, entangling of leather rollers and rollers and the like are solved.

Description

technical field [0001] The invention relates to the technical field of chemical fibers, in particular to a preparation method of bamboo charcoal fiber blended yarn. Background technique [0002] Bamboo charcoal fiber is made of moso bamboo as raw material, and adopts a new calcination process and new technology of pure oxygen high temperature and nitrogen barrier delay, which makes the micropores inherent in bamboo charcoal more refined and honeycombed, and then combined with the trend of honeycomb microporous structure It is made by melt spinning polyester modified chips. This unique fiber structure design has the characteristics of moisture absorption and breathability, antibacterial and antibacterial, warm in winter and cool in summer, green and environmentally friendly. Viscose fiber, a major species of man-made fiber. Alkaline cellulose is made from natural cellulose by alkalization, and then reacted with carbon disulfide to form cellulose xanthate, and the viscous so...

Problems solved by technology

This kind of spinning method has high neps in the yarn, more coarse details, larger hairiness, poor quality, low return flower utilization rate of about 80%, low yarn production rate of 1.25, increased cost, and spinning is affected by temperature and humidity. Larger, poor applicability, semi-finished products stick to the lap, difficult to form a web, the phenomenon of wrapping rollers around the rollers is serious, and uneven mixing leads to uneven fiber distribution in the yarn body, uneven fabric surface after single dyeing, and large spots on the fabric surface chromatic aberration
