Problems solved by technology

[0004] However, there are also some disadvantages in twisting ultra-fine nylon elastic yarns with covered silk spindles: 1. Since the twisting of covered silk spindles is single twist, that is, only one twist is added to nylon elastic yarns after one turn of the spindle. low twist efficiency
Reducing the weight of the feeding bobbin means reducing the amount of silk in the feeding bobbin, which will increase the number of doffing times of the feeding bobbin, increase the knot of the twisted yarn, and reduce the quality of the nylon elastic yarn product

Abstract

The invention discloses a twisting method of ultra-fine nylon stretch yarn and a device thereof, belonging to the technical field of textile. The invention utilizes a doubler winder with polyurethane fibre drawing to process the two-for-one twisting feeding tube of the ultra-fine nylon stretch yarn, and then utilizes a two-for-one twister spindle to twist the ultra-fine nylon stretch yarn. The invention utilizes one bout plus two turns of a two-for-one twisting spindle, which has the advantages of constant air ring, constant tension and big package, so that the twisting method of the invention improves production efficiency, effectively realizes myriametre knot-free yarn, improves the equality index of thrown silk degree of twist, and lowers energy consumption of yield per unit. The invention provides a new method and technical device for producing ultra-fine nylon stretch yarn with high efficiency, good quality and small energy consumption.

Description

technical field [0001] The invention relates to a twisting method and device for superfine nylon elastic yarn, belonging to the technical field of textile machinery. Background technique [0002] Ultra-fine nylon elastic yarn is often used in hosiery, elastic underwear, underwear and other fabrics. It is usually drawn with 12D----75D nylon low-elasticity yarn and 20D----40D spandex yarn at a ratio of about 1:3. It is made by twisting and plying. The traditional twisting method of ultra-fine nylon elastic yarn is to use a special winding machine to wind the processed nylon yarn on the sided bobbin dedicated to the covering yarn machine, and then use the covering yarn spindle to twist the nylon yarn and spandex yarn. After drawing, it is paralleled and twisted. The specific structure is as figure 1 As shown, the belt pulley 3-8 equipped with the hollow spindle bar 3-4 is installed on the spindle base 3-9 through the bearing transition, and the spindle base 3-9 is installed ...
