Embodiment Construction

[0027] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0028] see figure 2 with image 3 Shown, the present invention discloses a kind of low torque spinning technique; This technique comprises the steps:

[0029] (1) First, the spinning frame is fed with double rovings, and the two rovings always keep a certain distance in the drafting area of ​​the drafting device of the spinning frame and move downward equally. The bar is sent to the fiber arrangement adjustment device installed between the front roller 10 and the yarn guide hook 20 after going out of the front jaw of the spinning frame, that is, on the dividing wheel 60 .

[0030] (2) Each strand is immediately divided into more than two fiber bundles by the separator wheel 60, and the fiber bundles first rotate around the center of rotation ...

Abstract

The invention discloses low-torque spinning process. The process comprises following steps: (1) firstly, a spinning frame adopts a double-roving feeding method, two rough yarns are drafted to form fiber strands through a drafting device of the spinning frame and fiber strands coming out of a front jaw of the spinning frame after drafting are conveyed to be installed at a fiber arraying and adjusting device between a front roller and a yarn-guide hook; (2) the fiber arraying and adjusting device is used for cutting fiber strands into at least two strands of fiber bundles, the fiber bundles firstly wind around the itself rotary center under effect of twisting force and are combined to wind around again the center of the fiber bundles to be twisted to be solospun single yarns and then two solospun single yarns are combined to twisted as right-laid single yarns; (3) the right-laid single yarns are subjected to false-twisting operation through a false twister, left-laid single yarns formed by false twisting operation are conveyed to steel collars and steel travelers for twisting and finally are wound to be finished yarns. The low-torque spinning process has following beneficial effects: without decreasing yarn strength of low-torque spinning process, yarns featuring lower twisting force, fewer fibers and higher strength can be spun than conventional ring-spun yarns; and cost of yarns remains unchanged.

Description

technical field [0001] The invention relates to a spinning process, in particular to a low-torque spinning process. Background technique [0002] see figure 1 As shown, ring spinning is exactly a method of mechanical spinning in which the yarn guide hook 20, the spindle 50, the steel ring 30, and the traveler 40 are twisted, and the front roller 10 is drafted. [0003] Ring spinning is the most widely used and most common spinning method in the market at present. The sliver or roving fiber strips after drafting are introduced by the ring traveler, and the winding speed of the bobbin is faster than that of the traveler. , Cotton yarn is twisted to make spun yarn. It is widely used in various staple fiber spinning projects. Such as carding, combing and blending, the traveler is driven by the bobbin through the yarn sliver to rotate around the ring. Twisting, at the same time, The friction of the steel ring makes the rotation speed slightly smaller than that of the bobbin to ...
