Problems solved by technology

During the microwave fixing process, the surface color flower and the color difference between the front and back are quite serious, so that it is difficult to match the color, and the production practicability is not strong, so it can only be used as a general reference
Therefore, the rapid proofing technology in cold pad-batch dyeing is still under exploration and development

Embodiment 1

[0012] Dye formula: remazol 3RS yellow 8.35g / l, remazol 3BS red 1.8g / l, remazol CA blue 2.63g / l;

[0013] Alkaline formula: pure minus 10-30g / l, soaking soda 30-50g / l.

[0014] Fabric: Silk cotton.

[0015] Before padding, mix the dyeing solution and lye in a ratio of 3-5:1-2, dip the fabric for 2-5 seconds, and roll it with a padding car, with a pressure of 2-5kg / cm 2 , speed 5-25 m / min. Cut a piece of fabric after padding, place it flat in a plastic bag, seal it after removing the air, fix it on a mechanism and place it in a water bath at 40-75°C for 40-80 minutes (or by hand). Take out the fabric, wash the unfixed dye with hot water, warm water and cold water respectively, then squeeze dry, dry the cloth to absorb water, gradually iron dry, balance at room temperature, and match the color.

Embodiment 2

[0017] Dye formula: remazol H-X black 10g / l, remazol RGB navy blue 36g / l, Jincheng HF-GD red 23.5g / l

[0018] Alkali formula: pure water 30-50g / l, bubble alkali 70-100g / l.

[0019] Fabric: Silk 02 Crepe Chine

[0020] Before padding, mix the dyeing solution and lye in a ratio of 3-5:1-2, dip the fabric for 2-5 seconds, and roll it with a padding car, with a pressure of 2-5kg / cm 2 , speed 5-25 m / min. Cut a piece of fabric after padding, place it flat in a plastic bag, seal it after removing the air, fix it on a mechanism and place it in a water bath at 40-75°C for 40-80 minutes (or by hand). Take out the fabric, wash the unfixed dye with hot water, warm water and cold water respectively, then squeeze it dry, dry the cloth to absorb water, iron it gradually, balance the room temperature, and check the color.

Embodiment 3

[0022] Dye formula: remazol H-X black 10g / l, remazol RGB navy blue 36g / l, Jincheng HF-GD red 23.5g / l

[0023] Alkaline formula: pure minus 30-50g / l, soaking soda 70-100g / l.

[0024] Fabric: silk striped

[0025] Before padding, mix the dyeing solution and lye in a ratio of 3-5:1-2, dip the fabric for 2-5 seconds, and roll it with a padding car, with a pressure of 2-5kg / cm 2 , speed 5-25 m / min. Cut a piece of fabric after padding, place it flat in a plastic bag, seal it after removing the air, fix it on a mechanism and place it in a water bath at 40-75°C for 40-80 minutes (or by hand).

Abstract

The invention discloses a quick fent method for cold rolling pile dyeing. The quick fent method for cold rolling pile dyeing is characterized by including the following steps: mangling make-up; fabrics slop padding; sample shearing plastic packaging; flipping fixation in hot-water bath; washing floating color; water absorption iron dry; balance color. Compared with the present technology, the invention have the following advantages: 1, the fent hand sample has uniform colors, positive and negative color difference CMC(2,1)DE is less than 1; the color is the same with that of the pile setting method, (which is close to or achieves 5 grade rated by the color changing cendre sample card according to the GB250-1984, ISO 105-02 1984 assessment,) which can be used in thicker cotton type fabrics, or can be used in relative thin fabrics such as silk brocade cloth. 2, the process can be completed in 2 hours from mangling make-up to color sample output, which satisfies the fent requirement of the regular production.

Description

technical field [0001] The invention relates to a rapid proofing method for cold pad-batch dyeing. In particular, it is a fast and accurate proofing method that can be applied to thick and thin fabrics at the same time. Background technique [0002] Cold pad-batch dyeing technology is an energy-saving dyeing technology that was first developed abroad and applied to cotton fabrics in the mid-to-late 20th century when energy was increasingly scarce. It was only in the 1980s that China began to develop this dyeing technology. The application of this dyeing technology on thicker cotton fabrics is relatively mature. The application on relatively thin fabrics such as silk is rare. There are two main reasons for the slow promotion and application of cold pad-batch dyeing technology. One is the slow speed of proofing, which takes 24 hours to make a sample, and the delivery date of the order is not easy to guarantee; the other is that cold pad-batch dyeing uses reactive dyes. It ...
