Example Embodiment

[0020] Example 1: Rannin dye reduces the dyeing time when the cashmere red is stained, and the quantity of the Lanninin dye is ≤1% by the weight percentage of the fabric: Step A1: Heat the dyeing liquid to 25 ° C, then acetic acid or formic acid was added to adjust the dye pH to 4, and the weight percent of the fabric was added, and the 1.5% fatty amine polyoxyethylene ether cyclo-nonionic surfactant was added, and then the cycle was at least 10 min; Step A2: The weight percentage of the fabric was added no more than 1% of the Ranna dye, and then cycled for at least 10 minutes, then the rate was raised to 80 ° C according to the rate of 0.5 ° C / min, and the final temperature was completed at the end of 40 min; Step A3: Flush the fabric After the rinsing, the fabric is post-treated, and ammonia water is added to the treatment liquid, so that the pH of the treatment liquid reaches 7, with a weight percent of the fabric, simultaneous addition of 2.0% sodium sulfonate composite - no...

Example Embodiment

[0021] Example 2: Ranna dye shortens the dyeing time when the cashmere red is stained, and the amount of the Lanninin dye is ≤1% by the weight percentage of the fabric: Step A1: Heat the dyeing liquid to 35 ° C, then acetic acid or formic acid was added to adjust the dye pH to 6. 5, with a weight percent of the fabric, simultaneously added 2.0% fatty amine polyoxyethylene ether cyclic - nonionic surfactant, then cycles at least 10 min; step A2 : Add no more than 1% of the Ranninin dye, then circulate for at least 10 minutes, then warm up to 99 ° C according to the rate of 1.5 ° C / min, and then heat the temperature after the temperature is completed; step A3: The fabric is rinsed, and the fabric is followed by the fabric after the end of the flushing. The pH of the treatment liquid is added such that the pH of the treatment liquid reaches 8, and the weight percentage of the fabric is added, and the 2.0% sodium sulfonate compound is added to the negative or ion detergent; step A4 ...

Abstract

The invention discloses a method for shortening dyeing time during application of lanasol dye to cashmere non-red dyeing, and relates to a dyeing method. The method comprises 6-10 steps according to different dye materials. Compared with the prior art, the method has the advantages that novel fatty amine modified polyoxyethylene ether anionic and nonionic surfactant dyeing auxiliaries are adopted, so that the operation time when the dye auxiliaries are added is shortened, the heat preservation time during dyeing post-treatment and the hot washing frequency during post-treatment are shortened and reduced, the production efficiency is greatly improved, the cost is saved, the production concept of energy conservation, emission reduction, quality improvement and efficiency improvement is met, and the product quality and the production delivery time are guaranteed.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a dyeing method. Background technique [0002] Before dyeing cashmere products, reactive, acidic, or neutral dyes are generally selected for dyeing. The auxiliary agents basically use traditional FFA, Abaig B, SET, and other auxiliary agents for dyeing production. The traditional process uses a lot of auxiliary agents, and the production time of the process It is too long, the cost of auxiliaries and water, electricity and electricity is high, and the wool takes a long time in dyeing production, which has a great impact on the feel of raw materials and fiber strength, especially for the production of worsted and semi-worsted product orders, pre-treatment and post-dyeing process steps Many, long cleaning time, after the production of medium-dark order is completed, many batches of inspections found that the strength of raw materials has dropped, sticky, and wrapping around the to...
