Preparation method of pure spun blended yarn of horn gourd fiber

Abstract

The invention relates to a preparation method of calotropis gigantean fiber pure spinning blended yarn. Through strip forming, drawing, rough yarn and fine yarn processes of calotropis gigantean fiber, the calotropis gigantean fiber pure spinning blended yarn is prepared. Strip forming is conducted in the mode that the calotropis gigantean fiber is combed by metal card clothing on the surfaces ofa feeding stabbing roller and an opening roller, is divided into a single-fiber state, is transmitted and enters a strip forming cylinder which rotates under the effect of negative pressure airflow which is generated by an exhaust fan, is parallelly arrayed along the inner side of the cylinder wall of the strip forming cylinder in the circumferential direction, and slides into a strip forming groove and is stacked into annular fiber strands under the effect of centrifugal force; the strip forming cylinder is a rotation body and is composed of a cylinder body and a cylinder shaft, an opening isformed in one end of the cylinder body, and the cylinder body is composed of a cylinder bottom, a cylinder wall and the strip forming groove which makes the cylinder bottom connected with the cylinder wall; the diameter of the cylinder body is gradually increased from the cylinder opening to the strip forming groove, and the cylinder shaft is located on the outer side of the cylinder body and isvertically connected with the center of the cylinder bottom. According to the preparation method, strip forming is successfully conducted under the situation that the fiber is less damaged, and the prepared calotropis gigantean fiber is low in short fiber content and high in quality.

Description

technical field [0001] The invention belongs to the field of fiber preparation, and in particular relates to a preparation method of pure spun blended yarn of horn gourd fiber. Background technique [0002] Crow's horn melon fiber is grown from the seeds of Crow's horn melon, mainly composed of cellulose, which belongs to natural plant fiber. The kapok fiber is similar to the kapok fiber, which can replace the kapok fiber for textile production. The woven fabric not only has the smooth texture of silk, but also has the breathability and comfort similar to cotton fabric. At the same time, the cross section of the kapok fiber is hollow. It can be used as potential water-absorbing and oil-absorbing materials, thermal insulation materials and buoyancy materials, etc., and has broad application prospects. [0003] The spinning process of the horn gourd fiber in the prior art must go through processes such as opening and cleaning, carding, drawing, roving and spun yarn, wherein t...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the problem that the traditional carding method has a large damage to the horned melon fiber and cannot realize the smooth slitting of the horned melon fiber, and provides a method that can realize the smooth slivering of the horned melon fiber under the condition of relatively low damage.
