chemical fiber

The dyeing and finishing of chemical fiber blended products need to be treated by liquid alkali pretreatment, which involves hot washing, pickling, dyeing and washing.

Whether the energy saving and emission reduction can be realized by shortening the process flow can be considered by the business operators.

Hu Weiliang, chief technology officer of the company, has 20 years working experience in printing and dyeing industry.

Since last year, he has embarked on the research of the subject, starting from the choice and matching of dyes, and seeking the dye preparation scheme with good color and stability.

After numerous experiments, in May this year, the new process of dyeing and finishing was successful and put into production.

According to the introduction, "one bath for dyeing and finishing" is the combination of the first 5 ways in the original 6 processes. Besides special colors, more than 95% of the fabric dyeing can be applied to the technology.

After the new technology was applied, the company had an average of one cylinder of cloth per unit, and the sewage discharged from 12 tons to 4 to 6 tons. The electricity consumption was reduced from 160 kilowatt hours to 100 kwh. The steam consumption was reduced from 1.5 tons to 1.1 to 1.2 tons, and the production time was reduced by 2 hours, and the production efficiency was improved.
