Problems solved by technology

However, the defects of the yarn can be hidden during normal dyeing, but they will be clearly exposed during single dyeing. To eliminate them will increase the cost and it is difficult to deal with them.
Moreover, after the pure polyester staple fiber or cotton fiber passes through the carding process, it cannot be carded into a single fiber state due to the insufficient carding degree, and the electrostatic phenomenon is easy to produce polyester or cotton fiber neps, which makes needles and woven gray fabrics exist after single dyeing. Uneven slub and white star phenomenon
Even if the carding speed and card clothing configuration are reasonable, the reliability of product quality cannot be effectively guaranteed, and uneven slubs and white stars may still occur.

Embodiment

[0020] The production technology of single-dyed yarn comprises the steps:

[0021] 1) Raw material control: use raw cotton with good slenderness and uniformity, low short-lint rate, and few defects, and use 1.33 dtex*38 mm superior high-strength cotton polyester fiber for knitting polyester;

[0022] 2) Process flow:

[0023] a: Carding: adopt the process principle of light weight, strong carding and low speed;

[0024] b: Drawing head: 6 pieces are combined, and a small draft design is adopted to design a small draft, and the unevenness caused by the draft is reduced.

[0025] c: Two parallels and three parallels: two parallels and three parallels use 8 parallels to ensure that the pressure of the cradle is consistent at both ends, and use large-diameter top rollers;

[0026] d: Roving: Adopt JWF1415 four-roller roving frame with servo motor frequency conversion adjustment function, which can reduce the details of switch machine and accidental drafting, ensure the consisten...

Abstract

The invention discloses a production process of single dyed yarn, which comprises the following steps: 1) raw material control; 2) process flow: carding, doubling, double doubling, triple dowing, roving, spun yarn, winding. Compared with the prior art, the invention can remove the slub defects and white stars caused by single dyeing at low cost, and also solves the problem of sufficient carding of polyester.

Description

technical field [0001] The invention belongs to the technical field of textile technology, in particular to the production technology of single dyed yarn. Background technique [0002] Single-dyed yarn is polyester-cotton yarn that is dyed only one of the fibers when it is woven into fabrics. It only dyes cotton and does not dye polyester or only dyes polyester and does not dye cotton. This can save dyeing costs and be more environmentally friendly. The fabric has a blank effect, and the clothes made of it are more fashionable and unique in style. However, the defects of the yarn can be concealed during normal dyeing, but they will be clearly exposed during single dyeing. To eliminate them will increase the cost and it is difficult to deal with them. Moreover, after the pure polyester staple fiber or cotton fiber passes through the carding process, it cannot be carded into a single fiber state due to the insufficient carding degree, and the electrostatic phenomenon is easy ...
