Problems solved by technology

[0003] Compared with viscose filament and cupro filament, lyocell filament has obvious advantages in strength and dimensional stability, but the traditional sand washing process will have many problems in the dyeing and finishing of fabrics, especially for fabrics. There are surface creases, scratch marks, and uneven jeanette, so the authenticity rate is not high and the loss is large

Embodiment 1

[0021] A dyeing and finishing method for lyocell filament fabrics. The lyocell filaments are taken for sizing and warping, and then weaved on a machine to obtain gray cloth. Air-flow dyeing, opening width, tentering, mechanical softening and pre-shrinking can obtain the target product lyocell filament fabric.

[0022] In this embodiment, the precision after warping is 60 threads / cm, the weft density is 30 threads / cm, and the lyocell filaments used are 120D / 50F.

[0023] In the process of open-width desizing, first use solution 1 containing 2g / l NaOH and detergent 209 0.5g / L for treatment, then place it in solution 2 containing 1g / L acetic acid for treatment, and then dry it to complete. There are six water tanks through which solution 1 passes, and the temperature of each water tank is sequentially controlled to 40°C, 60°C, 90°C, 95°C, 80°C and 60°C according to the traveling direction of the gray cloth.

[0024] The air-flow opening is carried out in an air-flow dyeing machi...

Abstract

The invention relates to a dyeing and finishing method of lyocell filament fabric. The dyeing and finishing method comprises the following steps: warping lyocell filaments, weaving on a machine to obtain grey cloth, and sequentially performing open-width desizing, airflow splitting, cellulase treatment, airflow dyeing, scutching, tentering, mechanical softening and preshrinking on the grey cloth to obtain a target product. Compared with the prior art, the prepared fabric is high in yield and low in loss, creases on the surface of the fabric can be reduced or even eliminated, scratch marks are avoided, and peach skin fluff on the surface of the fabric is uniform.

Description

technical field [0001] The invention belongs to the technical field of preparation of functional fiber fabrics, and relates to a dyeing and finishing method for lyocell filament fabrics. Background technique [0002] Lyocell filament is Lenzing AG Paris, France – October 6, 2017 – Lenzing Group is the first to launch a new product of environmentally friendly cellulose filament to the high-end clothing market, thereby leading the luxury fashion industry to a new level. The new TENCEL Luxe brand filament fibers are manufactured using the Lenzing Group's leading closed-loop lyocell production process. As the population continues to grow and consumers pay more attention to sustainable development, the demand for environmentally friendly fabrics in the fashion industry is gradually increasing. In addition to eco-environmental protection, consumers of luxury clothing have more requirements, and the fabrics need to achieve unparalleled quality in drape, smoothness, and bright colo...
