Method for preparing finger spindle compact spinning knitted flannel

Abstract

The invention discloses a method for preparing finger spindle compact spinning knitted flannel. The method comprises the following steps of: dyeing fibers, mixing and opening the fibers, carding machine, gilling in two passes, combing machine, gilling in two passes, drawing, roving, finger spindle compact spinning fine complexing, two-for-one twisting and forming finished knitted flannel, wherein 1) a negative pressure device is additionally arranged at a front roller outlet, so that the fibers can move according to a specified motion track, and short fibers which influence smoothness of resultant yarns are adsorbed; and 2) the spinning spindle used in the process of twisting the fibers out of the front roller is a spindle with a spindle end finger, wherein the spindle comprises a spindle body, and is characterized in that the spindle end finger is arranged at the tail end of the spindle, and the other end of the spindle end finger is connected with a yarn guide hook. According to the technical scheme, due to the combination, the twist required by tight yarns with the specified smoothness is reduced, the production efficiency is correspondingly improved by 10 to 30 percent, the consumption is synchronously reduced, and the yarn breakage is reduced by 50 percent.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a method for producing knitted fleece by combining finger spinning technology and compact spinning technology. Background technique [0002] In the traditional spinning mechanism, the fibers are more or less free and random in the process of drafting, and there are irregular and uncontrolled twisting triangles in the yarn formation. During the winding process, the air circle is large, which leads to the congenital defect of yarn hairiness. It can be said that the traditional spinning principle cannot really reduce the occurrence of hairiness. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a three-dimensional low-carbon wool worsted spinning method that can reduce the randomness of fibers in the drafting process, reduce the discreteness of production, reduce and eliminate spinning balloons, and improve the quality of wo...

[0002] In the traditional spinning mechanism, the fibers are more or less free and random in the process of drafting, and there are irregular and uncontrolled twisting triangles in the yarn formation. During the winding process, the air circle is large, which leads to the congenital defect of yarn hairiness. It can be said that the traditional spinning principle cannot really reduce the generation of hairiness.
