Abstract

The invention relates to a cotton or viscose/chinlon/spandex seamless underwear one-bath-process dyeing technology, and belongs to the technical field of a knitwear dyeing technology. The technology comprises the following steps: keeping to-be-dyed cotton or viscose/chinlon/spandex seamless underwear in a dyeing jar, adding water to a specified water amount, heating up to 25-35 DEG C, sequentially adding salt or anhydrous sodium sulfate and a leveling agent, and keeping operating for 5-10min; then adding a reactive dye, a weak acid dye or a neutral dye and operating for 5-10min; heating up to 58-62 DEG C at 0.5-1 DEG C/min, then adding sodium carbonate and preserving heat for 30-50min; neutralizing sodium carbonate with dyeing acid, slowly regulating pH value to 6-7, heating up to 93-97 DEG C at 1-1.5 DEG C/min after rotating evenly and preserving heat for 40-60min; and cooling, draining, and finally carrying out post-treatment. The technology disclosed by the invention can effectively shorten dyeing process, shorten dyeing time, improve production efficiency, reduce discharged pollution and lower dyeing cost.

Description

technical field [0001] The invention relates to a one-bath dyeing process of cotton or viscose / nylon / spandex seamless underwear, which belongs to the technical field of knitwear dyeing technology. Background technique [0002] Existing cotton or viscose, the dyeing of the seamless underwear that interweaves with nylon, spandex mainly is to dye with two-bath method. According to the different organizational structures of knitted fabrics, there are generally two dyeing processes: one is to dye cotton or viscose with reactive dyes, and then use weak acid dyes or neutral dyes to over-dye nylon and spandex; Use weak acid dyes or neutral dyes to dye nylon and spandex, and then use reactive dyes to over-dye cotton or viscose. The main problems in the existing process are: the process is long, usually 8-10 steps, the dyeing time is long, generally 10-12 hours, and it is easy to damage the product and pilling, unstable color, water consumption, energy consumption, Large amount of...
