Double-drafting centralized control spinning device and spinning method

Abstract

The invention provides a double-drafting centralized control spinning device and a spinning method. A left middle hollow roller sleeve and a right middle hollow roller sleeve are communicated with a lower middle hollow roller shaft, the surface of the left middle roller sleeve or the surface of the right middle roller sleeve is provided with a first strip-shaped groove, and a front right hollow roller sleeve and a rear left solid roller sleeve or a front right solid roller sleeve and a rear left hollow roller sleeve fixedly sleeve a lower front solid roller shaft; the surface of a right hollowor front left roller sleeve is provided with a second strip-shaped groove, the left side of the lower middle hollow roller shaft is communicated with a negative-pressure draught fan through a negative pressure pipe, and front centralized speed-variable extraction control and rear vortex transfer twisting control are achieved by adopting the first strip-shaped groove for acting on fiber strands before the fiber strands enter the lower middle roller and the fiber strands obtained after output. A hollow air suction insert is arranged in the front left or front right roller sleeve, the left sideor the right side of the air suction insert is communicated with the negative-pressure draught fan through the negative pressure pipe, and negative pressure acts on the fiber strands output by the lower front roller through the second strip-shaped groove to achieve parallel centralized control before the fiber strands are twisted.

Description

technical field [0001] The invention relates to the new technical field of ring spinning, in particular to a spinning device and spinning method with double-draft compaction control. Background technique [0002] With the continuous advancement of the times, people's requirements for clothing materials continue to increase. At present, the textile and clothing industry is in an era of pursuing fashion, diversification and high quality. Therefore, new requirements are put forward for the development of textile raw materials and textile technology. Among them, high-quality, high-performance textiles and clean production and processing have become the main development direction of the modern textile industry and an effective way to improve product grades and added value. With the improvement of modern living standards and the acceleration of the pace of work, the high shape retention and easy care of textiles have become important attributes and distinctive symbols of high-qua...

AI Technical Summary

Problems solved by technology

However, there are still many problems in shape retention of fabrics made of different fiber materials. For example, cotton fabrics are easy to wrinkle when worn, poor flatness after washing and drying, and need to be ironed; Chemical fiber fabrics are easy to arch and keep shape when worn

Many practical problems such as insufficient shape retention, unstable shape retention effect, and difficulty in controlling the environmental protection index of the existing shape retention technology have become serious obstacles to high-quality textiles, and can no longer meet people's needs for high-quality clothing in modern society.
