Abstract

The invention relates to a self-twist hollow ingot special for jet blast vortex spinning which includes a fibre inlet (1) and a hollow ingot channel (2), a surface groove (3) is opened on the fibre inlet (1) and the hollow ingot channel (2), the fibre inlet (1) diameter D1 is larger than the hollow ingot channel (2) diameter D2, the fibre inlet (1) chamfer angle theta is 30-60 degree, an inner surface of the surface groove (3) is streamline. The self-twist hollow ingot provided by the invention can reduce loss amount of fibre, increase utilization rate of raw material, accordingly reduce cost for producing yarn; at the same time, enhance cohesive force among fibre in yarn greatly, accordingly, strong force of final yarn is increased.

Description

technical field [0001] The invention belongs to the field of air-jet vortex spinning, in particular to a self-twisting hollow ingot for air-jet vortex spinning. Background technique [0002] Air-jet vortex spinning has become one of the fastest-growing new spinning technologies due to its high-yield and high-speed performance. However, there are still some problems with yarn quality, mainly in yarn details and low strength, which limits its products. Expansion of development application fields. The main reasons are as follows: 1. In terms of processing methods, although the efficiency is greatly improved compared with mechanical twisting due to the use of swirling airflow twisting, the decline in fiber control will easily lead to fiber loss, which makes The details of the final yarn increase and the strength decreases; 2. In terms of yarn structure, the final yarn of air-jet vortex spinning is parallel fibers in the middle and outer coating fibers, which is different from t...
