Embodiment Construction

[0018] In order to further illustrate the technical points of the present invention, the present invention will be further described below in conjunction with practical examples.

[0019] Take the preparation of 1000 liters of printing dyes as an example.

[0020] A kind of printing dye, each component and its weight in its raw material composition are: methyl hydroxyethyl cellulose 14.5kg; nitrobenzene 4.5kg; sodium hexametaphosphate 1kg; sodium bicarbonate 40kg; carboxamide 80kg; Base methyl cellulose 50L; the rest is water.

[0021] The preparation method of above-mentioned printing dye, comprises the following steps:

[0022] (1) Take materials according to the formula ratio;

[0023] (2), under normal temperature, add 500 liters of water in 1000 liters of containers;

[0024] (3), turn on the low-speed agitator 750 rpm, constant speed; add sodium hexametaphosphate, after it is fully dissolved and the water quality softens, add 100 liters of nitrobenzene with a concentr...

Abstract

The invention relates to the technical field of textile printing and dyeing, and particularly discloses a printing dye and a preparation method thereof. The printing dye comprises the following components in percentage by weight: 1 to 2 percent of methyl hydroxyethyl cellulose, 0.8 to 1.2 percent of nitrobenzene, 0.3 to 0.5 percent of sodium hexametaphosphate, 5 to 6 percent of sodium bicarbonate, 7 to 8 percent of carbamide, 6 to 7 percent of hydroxypropyl methyl cellulose and the balance of water. The components are added into water, and are uniformly stirred at normal temperature for later use. When the printing dye is used as an active printing dye, high color yield is ensured, and the dye is saved; the printing dye is a novel excellent printing dye.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a printing dye and a preparation method thereof. Background technique [0002] At present, sodium alginate organic printing dye is the most used in my country's printing and dyeing industry. Sodium alginate, also known as sodium alginate, kelp gum, alginate, alginate, is a natural polysaccharide carbohydrate extracted from kelp. However, since the main raw material for the preparation of sodium alginate is kelp, not only the resources are limited, but also the cost is high. In order to promote the development of the printing and dyeing industry, it has become an urgent need to develop a new generation of printing dyes. Contents of the invention [0003] According to the problems existing in the prior art, the invention provides a printing dye with low cost and simple preparation process. The printing dye of the present invention uses polysaccharide compoun...
