Abstract
The invention discloses a color stripping method of cotton dyed by reactive dye and wool and silk dyed by acid dye. The method comprises the steps of soaking fabric needing to be subjected to color stripping into a CY-770 water solution and a penetrant JFC or CY-7P at the temperature of 40 DEG C, and treating for 10 minutes; feeding CY-730, then heating up to 95-100 DEG C (wool and silk can be heated up to 80-85 DEG C), and carrying out dipping treatment for 30-40 minutes (the time of dipping treatment is prolonged to 60 minutes if the colors of the wool and the silk are stripped at the temperature of 80-85 DEG C); after color stripping, washing with hot water with the temperature of 80 DEG C for 10-15 minutes, cleaning the damaged dye and washing with cold water. The color stripping method is safe and environment-friendly; a strong reducing agent can be generated in the presence of CY-730 and a catalyst, and the dosage of the strong reducing agent is 1/5 that of sodium hydrosulfite, but the color stripping effect is more superior.
Description
Technical field
The invention belongs to stripping method, be specifically related to the stripping method of a kind of Dyeing of Cotton Fabric with Reactive Dyes ACID DYES dye hair and silk.
Background technology
Stripping agent made by the sodium hydrosulfite that adopts of stripping of traditional activated dyestuff and ACID DYES more, but sodium hydrosulfite exists easy spontaneous combustion, easily decomposes, and releases SO2 and makes environmental pollution, the shortcoming such as can not to use under acid and hot conditions.
Summary of the invention
In order to overcome the above-mentioned defect that prior art field exists, the object of the invention is to, providing a kind of Dyeing of Cotton Fabric with Reactive Dyes ACID DYES to contaminate the stripping method of hair and silk, safety and environmental protection.
The stripping method of Dyeing of Cotton Fabric with Reactive Dyes ACID DYES provided by the invention dye hair and silk, the fabric CY-770 aqueous solution that need strip and penetrating agent JFC or CY-7P immerse in 40 DEG C time, process 10 min; Add CY-730, be then heated to 95-100 DEG C (wool, silk can use 80-85 DEG C), impregnation process 30-40 min (if wool, silk are stripped at 80-85 DEG C, 60 min be extended to); After stripping, 80 DEG C of hot water wash 10-15 min, clean the dyestuff destroyed, then cold wash.The amount ratio of CY-730 and CY-770 is 1:1.9.
The stripping method of Dyeing of Cotton Fabric with Reactive Dyes ACID DYES dye hair provided by the invention and silk, its beneficial effect is, safety and environmental protection, CY-730 and catalyst action, can generate strong reductant, and consumption is 1/5 of sodium hydrosulfite, and effect of stripping is more excellent.
Detailed description of the invention
Below in conjunction with an embodiment, the stripping method of Dyeing of Cotton Fabric with Reactive Dyes ACID DYES dye hair provided by the invention and silk is described in detail.
Embodiment
The fabric CY-770 aqueous solution that need strip and penetrating agent JFC or CY-7P immerse in 40 DEG C time, process 10 min; Add CY-730, be then heated to 95-100 DEG C (wool, silk can use 80-85 DEG C), impregnation process 30-40 min (if wool, silk are stripped at 80-85 DEG C, 60 min be extended to); After stripping, 80 DEG C of hot water wash 10-15 min, clean the dyestuff destroyed, then cold wash.
Claims (2)
1. Dyeing of Cotton Fabric with Reactive Dyes ACID DYES dye hair and the stripping method of silk, is characterized in that: the fabric CY-770 aqueous solution that need strip and penetrating agent JFC or CY-7P immerse in 40 DEG C time, process 10 min; Add CY-730, be then heated to 95-100 DEG C (wool, silk can use 80-85 DEG C), impregnation process 30-40 min (if wool, silk are stripped at 80-85 DEG C, 60 min be extended to); After stripping, 80 DEG C of hot water wash 10-15 min, clean the dyestuff destroyed, then cold wash.
2. the stripping method of Dyeing of Cotton Fabric with Reactive Dyes ACID DYES dye hair according to claim 1 and silk, is characterized in that: the amount ratio of CY-730 and CY-770 is 1:1.9.
