example 1

[0020] Example 1: Use the accelerator to use the emerald green to dye better than ordinary colors

[0021] There are 900, 937.5Kg, 32 s Raw cotton yarn to be dyed. Existing dyes use 100% of a certain type of active B-GFN 18.281Kg, 100% of a certain type of active BES bright yellow 16.406Kg, and 562.5kg of sodium sulfate, and 21.6kg of an accelerator.

[0022]Conventional bath ratio dyeing is now used. Add appropriate amount of cold water to the tank; turn on the main pump for regular operation; pour the dye into the chemical material tank after melting in a small bucket in advance, return the water properly, heat it to an appropriate temperature with steam until the dye is completely dissolved, and add it within 15 to 20 minutes In the dyeing vat; then the backwater in the chemical material vat is appropriate, under stirring, the sodium sulfate is poured into, and is added in the dyeing vat in about 20 minutes; back to the half vat of water again, the accelerator (or the pat...

example 2

[0023] Example 2 Use the accelerator to use the bright blue spelled green to dye better than ordinary colors

[0024] In a certain type of six-window normal temperature and pressure U-shaped cylinder, there are 21 pre-treated s 850Kg of rayon elastic large circular machine knitted fabric. The dye is 100% of a certain type of brilliant blue B-KNR 38.25Kg; 100% of a certain type of blue B-FBN3.825Kg; 100% of a certain type of yellow 3BS yellow 3.995Kg; Yuanming powder 637Kg; accelerator 23.8Kg .

[0025] Add cold water to the vat, the bath ratio is about 10; turn on the main pump and other normal operations; the dye is melted in a small bucket in advance and then poured into the chemical vat, the return water is appropriate, and the steam is heated to an appropriate temperature until the dye is completely dissolved. Add it to the dyeing vat within 15 to 25 minutes; then return the water to the chemical material vat appropriately, pour the sodium sulfate into the dyeing vat und...

example 3

[0026] Example 3 uses the accelerator to dye the green of brilliant blue spelling with about 2.5 hours

[0027] With reference to the method of example 2, dye 350Kg21 s Cotton knitted jersey, all raw materials are input in proportion. It only takes 2 hours and 30 minutes from the beginning of feeding to the discharge of the cylinder.

Abstract

The invention relates to a clean production method for making reactive turquoise blue and brilliant blue more convenient to dye than general color. In the clean production method, an accelerator or a similar additive is specifically used as a color fixing agent to replace soda ash (or / and caustic soda) and the like for color fixing so as to dye or fix a single color or a matched color containing the reactive turquoise blue and brilliant blue and the like; therefore, the material addition and temperature rise are convenient, and direct rise and direct discharge are achieved; and after once soap boiling and subsequent cold washing for at most 4 to 5 times, color fixing by using the color fixing agent and softening by using a softener of the original plan are performed, so that under the condition of normal and qualified fastness, the obtained cloth does not have color spots, color dots or color bars, is uniform, and has the difference between a big sample and a small sample and shade band in rational ranges; therefore, the effects of more conveniently dyeing than the general color by using the soda ash, saving time, water, power and gas, remarkably saving energy and reducing emission and performing clean production are achieved.

Description

technical field [0001] The invention relates to a clean production method in the dyeing and finishing industry to make active turquoise blue and brilliant blue dye better than common colors. It endows the user with only using the so-called printing and dyeing auxiliaries or similar additives described in the patent publication number CN101168928A in the dyeing stage, and can obtain the series of ultra-thin dyes described in the patent application number 200810131400. When dyed by the short and fast dyeing method, the dyeing effect is better than common ordinary colors. It can be dyed with no color stains and uniform cloth surface under the conditions of fast feeding, fast heating (such as > 2°C / min.), only one soaping, and simplified, fast or near-extreme operations such as straight row 1. Qualified products with qualified fastness, green, blue and other colors that are difficult to dye with soda ash, including single and mixed colors; especially suitable for the ultra-sho...
