Abstract

The invention discloses a one-bath dyeing method for spandex and viscose. The method comprises the following steps: (1) knitting 2 parts by mass of viscose and 3 parts by mass of spandex blended yarns into a knitted fabric; (2) putting the knitted fabric into an overflow dyeing machine, adding water, adding a chelating agent and isopropanolamine in sequence, adjusting the pH to 4-5, heating to 60 DEG C, running for 20 minutes, adding an active dye, running for 30 minutes, adding a cation dye, running for 30 minutes, adding anhydrous sodium sulphate, running for 25 minutes, heating to 90 DEG C, running for 1 hour, cooling to 35 DEG C, draining water, and washing with hot water of 75 DEG C for 30 minutes; (3) putting the dyed knitted fabric into water of 35 DEG C, adding an acid soaping agent and hydroxypropyl methyl cellulose in sequence, heating to 90 DEG C, running for 40 minutes, adding cold water, overflowing, cooling to 15 DEG C, draining water, adding cold water, and washing for 20 minutes. The one-bath dyeing method for the spandex and the viscose provided by the invention has the advantages of simple production process, stability in process control and energy conservation.

Description
