Shape dyeing process for cotton/fibers

Abstract

The invention relates to a shape dyeing process for cotton / fibers. The process is characterized in that: cone yarns and yarn beams are placed in the same yarn carrier and dyed by the following steps at the same: 1, bleaching scouring; 2, dyeing; 3, neutralizing and soaping; and 4, color fixing and smoothing treatment. The process has the advantages that: the conventional idea and mode of production is broken through and the one-bath dyeing of two kinds of yarn shapes is realized; and by using the one-bath dyeing of the yarn beams, the process flow of yarn-dyed cloth is simplified, efficiency and carrying rate are improved, a production period is shortened, simultaneously a dye uptake rate is improved, the emission of sewage and environmental pollution are reduced, a utilization rate of equipment is increased, the production dilemma caused by insufficient dyeing equipment is reduced, the cost is reduced, and the requirements on level-dyeing property, repeatability and fastness of the conventional dyeing level are met.

Description

technical field

[0001] The invention relates to a cotton / fiber morphological dyeing process, which belongs to the technical field of yarn dyeing in the textile industry. Background technique

[0002] Pure cotton fabric is a natural fiber with excellent fiber properties, and is widely loved by consumers, and yarn-dyed products are even more favored by consumers. With the progress of society, more attention is paid to environmental protection. The cost reduction and process shortening of bleaching and dyeing process are particularly important for energy saving and emission reduction. When the existing yarn-dyed products are produced, the warp and weft yarns are produced and processed separately, and then weaved. This process is divided into two routes for separate production. The process is long and the production cycle is long, which increases dyeing costs, repetitive labor and sewage discharge. . Contents of the invention
