Novel air yarn equipment

Abstract

The invention discloses novel air yarn equipment comprising a needle-cylinder machine, wherein the needle-cylinder machine comprises a stander as well as yarn feeding discs, needle cylinders and yarn discharge discs, which are arranged on the stander; infilling devices are arranged on the needle cylinders; each infilling device comprises a fixed seat, wherein a vertically-extended yarn guide post is arranged in the middle of the fixed seat, a first sleeve is arranged at the periphery of the fixed seat, a yarn storage cavity holding a centre yarn disc is formed between the first sleeve and the yarn guide post, the yarn guide post is internally provided with a yarn guide hole communicated with a needle cylinder yarn feeding hole; and during yarn knitting, centre yarns of the centre yarn discs are filled into the needle cylinders together with unit yarns or filaments of the yarn feeding discs at the same time to be knitted to form primary-secondary yarns after passing through the yarn guide holes and the primary-secondary yarns are wound on the yarn discharge discs after passing through yarn discharging holes of the needle cylinders. According to the novel air yarn equipment disclosed by the invention, the primary-secondary yarns, a new yarn product, are knitted, and the cost is lower because the novel air yarn equipment is improved on the basic of a needle-cylinder machine.

Description

technical field [0001] The invention relates to a spinning device. Background technique [0002] The principle of the traditional needle cylinder machine is to weave the filament or single yarn into a net-like round belt yarn through a head similar to a circular knitting machine. This product is a basic variety of fancy yarn and has a wide market share. . The change of this kind of product can only be the change of unit yarn and count, and the product has great limitations. [0003] In 2010, an Italian supplier invented wool spraying yarn and its special machine. The principle is to pour the loose fibers into the net bag through the high-pressure airflow of the high-pressure gas injection device in the round belt yarn of the net bag shape, forming an outer net bag surrounded by the middle loose fiber. Special yarn, commonly known as "spray yarn", also known as "core yarn". Individual domestic suppliers have also begun to imitate such equipment. However, there are the fol...

AI Technical Summary

Problems solved by technology

However, there are the following disadvantages in woolen yarn: 1. Unevenness, high rate of defective products for a single thread; 2. Due to the high price of equipment and low output, the production cost is very high, and the spinning cost per kilogram is 50 yuan / kg

Therefore, although the sprayed wool yarn can expand the product extension and development space of the round tape yarn, the high price determines that it can only be a noble product and cannot be accepted by the public.
