Embodiment 1

[0009] Embodiment 1, take by weighing 210 kilograms of carboxymethyl starch (commercially available) according to the ratio of carboxymethyl starch 70% (weight percent), sodium alginate 28% (weight percent), 84 kilograms of sodium alginate, through pulverizing to 20-50 mesh, the above-mentioned powder is not put into the mixer and stirred and mixed at room temperature, and 6 kg (2% by weight) of light lubricating oil (commercially available) is pressurized into the mixer by an air pump, lightly moistened The oil is in the form of mist. Stir while spraying. Continue stirring after the oil spray is over. After mixing and stirring for a total of 1 hour, the printing paste can be obtained, which can be discharged and packaged. The finished product is beige powder granule, pH value: 6.5-7.0. During concrete use, add 5% (weight ratio) paste in 95% (weight ratio) cold water, and constantly stir, the viscosity of gained slurry is 40000-60000CPS, is used for dispersing, direct dyestuff...

Embodiment 2

[0010] Embodiment 2, take by weighing 216 kilograms of carboxymethyl starch (commercially available) by the ratio of carboxymethyl starch 72% (weight percentage), sodium alginate 25% (weight percentage), sodium benzoate 2% (weight percentage), 75 1 kg of sodium alginate, 6 kg of sodium benzoate, crushed to 20-50 mesh, put the above powder in the mixer and stir and mix at room temperature, take 3 kg (1%) of light ship oil and pressurize it through the air pump Spray into the mixer in the form of mist, and stir and mix for a total of 50 minutes to obtain the finished paste for printing. The product of this formula has good storage stability. Due to the addition of preservatives, it is mixed with water to make a paste slurry , even in summer, it can guarantee the same performance for half a month. It overcomes the defects of thinning, deterioration and easy leakage of paste slurry caused by bacterial reproduction, and also saves paste. It is used for dispersion and direct dye prin...

Embodiment 3

[0011] Embodiment 3, take by weighing 105 kilograms of carboxymethyl starch (commercially available) by the ratio of carboxymethyl starch 35% (weight percentage), sodium alginate 49% (weight percentage), sodium hexametaphosphate 15% (weight percentage) , 147 kg of sodium alginate, 45 kg of sodium hexametaphosphate, crushed to 20-50 mesh, put the above powder into the mixer and stir and mix at room temperature, take 3 kg (1%) of light moist The oil is pressurized and sprayed into the mixer by the air pump. The light lubricating oil is in the form of mist, and it is stirred while spraying. After the oil spraying is completed, the stirring is continued. After mixing and stirring for a total of 1 hour, the printing paste is obtained. After discharging, packaging That's it. The paste of this formula is suitable for reactive and direct dye printing paste.

Abstract

A printing thickener has composition (by wt.%) as carboxy methylamylose of 20-74.5%, sodium alginate of 20-70% and mineral oil of 0.5-25%. Its preparing process includes selecting materials a sper preparation ratio; grinding raw materials to be 20-50 millimcron; placing them into mixer for agitating, blending and spraying light lube, agitating continuously till raw materials being totally uniformed for obtaining product of printing thickener.

Description

【Technical field】 [0001] The invention belongs to a carrier for fabric printing and dyeing dyes, in particular to a paste for reactive, disperse or direct dye printing and a preparation process thereof. 【Background technique】 [0002] Sodium alginate pulp has a long history of being used as printing paste, and it is an ideal paste in printing applications. Its biggest feature is that it does not react with dyes, and it is easy to transfer dyes from paste to fibers. The printed pattern is clear and bright, with high color yield and good hand feeling. Not only suitable for printing on cotton, but also suitable for printing on wool, silk and synthetic fibers. [0003] The existing sodium alginate slurry is made of pure sodium alginate, which is mainly extracted from kelp. However, in recent years, with the application of sodium alginate in the food industry and pharmaceutical industry, seaweed resources are in short supply and the cost is obvious. In addition, the stability p...
