Problems solved by technology

It can be seen that the fabric has gone through the processes of sanding and napping, which will destroy the structure of the fabric, and because the surface of the fabric is fluffed by the processes of sanding and napping, the length of the fluff is limited, so that the fabric thermal performance is also limited

Abstract

The present invention relates to the field of yarn technology, in particular to a production device for down yarn. The production device uses two yarns to clamp loose fibers during plying and twisting to form down yarn. The production device includes a bulk fiber feeding device, a plurality of feeding roller pairs, an upper apron, a lower apron, and a twisting device. and winding devices, etc. The production device of the invention has a simple structure and is easy to assemble, and the produced down yarn has good bulkiness, good heat retention, low cost and high production efficiency. The thermal fabric produced by using the down yarn is light in texture, high in quality and low in price, can store more still air, and has good warmth retention property.

Description

technical field [0001] The invention relates to the technical field of yarns, in particular to a production device for down yarns. Background technique [0002] Down is a natural material with excellent thermal performance, which is mainly determined by the unique properties of down. Down has a unique flower-like structure, from which a down core grows radially many fine down filaments with a hollow structure, and each down filament splits into many small barbules and scales, thus building a multi-dimensional three-dimensional space for easy storage still air. The down and silk paper pieces repel each other, this is because the down has electric charges, and the electrostatic capacity is very small, as long as a very small amount of charge, there will be repulsion between the down, which makes the down not easy to form like other fibers. Felt together. These properties allow down to have more air storage space. In short, these characteristics make down have good bulkines...
