Embodiment 1

[0031] First, fold the two ends of the white 100% polyester fabric in half; use two medium-thick cotton strips with a width of 3 to 4 cm and a length of 30 to 40 cm to spirally wind the fold and middle of the folded fabric with cotton strips; use 1 to 2 cm , A cotton cloth strip with a length of 30~40cm will be tightly bound 10~11cm near the end of the fabric; the cloth strip is fixed with a thread. Then, 600g of the knitted fabric was wound on the distributor and placed in the dyeing kettle. Put 1.5g of the dye Disperse Red FB200% in the dye kettle of the supercritical carbon dioxide dyeing device. Turn on the heating system and refrigeration system to make the device reach the temperature required for dyeing at 90-100℃; turn on the high-pressure system to make the device reach the required pressure for dyeing at 22-25Mpa; separation pressure: 4-5MPa, separation temperature: 25-40℃ . After 50 to 60 minutes dyeing is completed. Take out the dyed fabric and iron it with stitc...

Embodiment 2

[0033] First, a medium-thick cotton cloth strip with a width of 9-10 cm and two white 100% polyester fabrics are woven into a twist braid. Then, 600g of the knitted fabric was wound on the distributor and placed in the dyeing kettle. Place 1.5 g of the dye Disperse Blue SF-2G 200% (Disperse Red ACE 100%) in the dye kettle of the supercritical carbon dioxide dyeing device. Turn on the heating system and refrigeration system to make the device reach the temperature required for dyeing at 90-100℃; turn on the high-pressure system to make the device reach the required pressure for dyeing at 22-25Mpa; separation pressure: 4-5MPa, separation temperature: 25-40℃ . After 50 to 60 minutes dyeing is completed. Take out the dyed fabric and iron it with stitches. Similarly, dye with Disperse Red ACE 100% dye. After dyeing, the fabric is blue with white flowers (or red with white flowers, such as figure 2 , image 3 , Figure 4 Shown), the color fastness to abrasion and rubbing is grad...

Embodiment 3

[0035] First, fold the white 65 / 35 polyester-cotton fabric in half; weave a long strip of cotton cloth with a width of 14 to 15 cm and the folded fabric into a braid, leaving the end of the fabric. Then, 600g of the knitted fabric was wound on the distributor and placed in the dyeing kettle. Place 1.5 g of the dye disperse dark blue HGL 200% in the dye kettle of the supercritical carbon dioxide dyeing device. Turn on the heating system and refrigeration system to make the device reach the temperature condition of 80~90℃ for dyeing; turn on the high pressure system to make the device reach the pressure condition of 25~27Mpa for dyeing; separation pressure: 4~5MPa, separation temperature: 25~40℃ . After 50 to 60 minutes dyeing is completed. Take out the dyed fabric and iron it with stitches. After dyeing, the fabric is blue with white flowers (such as Figure 5 Shown), the color fastness to rubbing is 3 grade and the color fastness to washing can reach 3.5 to 4.

Abstract

The invention relates to a supercritical carbon dioxide art dyeing method which comprises the following steps of: embroidering a fabric to be dyed by utilizing a needle, a thread, a rope, a wood rod and medium-thickness type cotton or a mixture thereof according to a predesigned pattern to cover the dyeing preventing part of the fabric to be dyed according to the design of the pattern; placing dye and the embroidered fabric to be dyed, which is fixed to a distributor, into a supercritical carbon dioxide dyeing device and dyeing at the temperature of 70-150 DEG C and the pressure of 18-30MPa for 50-100 minutes; then recovering carbon dioxide and the dye at the pressure of 4-5MPa and the temperature of 25-40 DEG C; and disassembling a covering object of the dyed fabric and ironing the dyed fabric. The fabric to be dyed is a blending fabric of terylene, polyester wool and polyester cotton, and the dye is dispersing dye; and in the embroidering process, the fabric to be dyed is subjected to pinched binding, string binding, laminated binding, knitting and binding and the mixture method thereof. The invention has the characteristics of short process flow, strong art effect, low comprehensive cost and no environmental pollution; and the product meets the requirement of GB18401-2003.

Description

Technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and relates to a textile art dyeing technology using dyes dissolved in supercritical carbon dioxide. Background technique [0002] The traditional textile dyeing and finishing industry has serious water pollution and the problem of damage to resources and the environment is prominent. Although various enterprises have adopted corresponding sewage treatment methods, the actual effect of printing and dyeing sewage treatment is still not ideal, which seriously pollutes the water resources environment and endangers people's lives and health. Resources and environmental issues are fundamental and strategic issues facing the sustainable development of human society. In 1987, the United Nations proposed a "sustainable development" strategy. In September 1996, the International Organization for Standardization (ISO) announced the ISO14000 environmental management system, which aims to pro...
