Embodiment Construction

[0016] 1. Experiment

[0017] The purpose of the experiment: to irradiate the natural paste sample in divided doses at room temperature and conduct qualitative and quantitative analysis, and obtain the radiation dose for the optimal viscosity and the maximum irradiation depth of the electron accelerator to the natural paste according to actual needs.

[0018] Experimental equipment: electron beam energy of electron accelerator / 10MeV

[0019] Experimental instruments: balance, water bath, thermometer, NDJ-1 rotary viscometer

[0020] sample:

[0021] (1) Guar gum, the manufacturer's code name is AS-80.

[0022] (2) Tamarind glue, the manufacturer's code name is CMT-80.

[0023] Experiment 1

[0024] Spread two samples of guar gum (AS-80) with sample numbers 1-1 and 1-2 respectively in two sample slots, and control the thickness of each sample within 4.5cm.

[0025] In addition, two samples of tamarind gum (CMT-80) with sample numbers 1-3 and 1-4 were spread in two sample s...

Abstract

The invention discloses a method for modifying a printing and dyeing paste. The printing and dyeing paste is a natural paste; and the natural paste is irradiated with an electron beam generated by an electron accelerator. The natural paste is guar gum or tamarind seed gum, and the cumulative dose of the irradiation is 5-70kGy. According to the invention, the electron accelerator is utilized to irradiate and degrade the printing and dyeing paste for textile-natural paste, so that the viscosity of the paste is lowered to the viscosity number beneficial to textile printing and dyeing, and the optimal irradiation dose of the viscosity number can be obtained. The invention is simple to operate, and has the advantages of high processing efficiency and low cost.

Description

technical field [0001] The invention relates to the modification technology of printing and dyeing auxiliaries, in particular to the modification method of natural paste. Background technique [0002] In textile printing, the paste controls the fluidity of the color paste and prevents the color from spreading. Printing quality such as clarity, vividness, dye penetration and bleeding depends mainly on paste properties. If the viscosity of the paste is too high or too low, a good printing effect cannot be achieved. [0003] At present, the printing pastes used abroad are almost all processed products of water-soluble natural polymer compounds, mainly including sodium alginate, carboxymethyl cellulose, rice bean gum, locust bean gum, guar gum, starch and its derivatives. things. Among these natural pastes, the price of sodium alginate continues to soar due to insufficient resources, and the supply is in short supply. Under such circumstances, countries all over the world ha...
