Embodiment 1
[0017] The nanometer material composition that is used for the bleaching of cellulose fiber fabric, this composition is made up of following composition by weight ratio:
[0018] Nanoscale silicon dioxide 40 parts
[0019] Sodium hexametaphosphate 20 parts
[0020] 40 parts of ethylene glycol phenyl ether
[0021] The production technology of described nanomaterial composition is:
[0022] 1) Mix nano-scale silicon dioxide, sodium hexametaphosphate, and ethylene glycol phenyl ether into a turbid solution according to the specified ratio;
[0023] 2) heating the turbid solution to 40-60°C, and maintaining this temperature until the entire process is completed;
[0024] 3) Use an ultrasonic disperser to carry out ultrasonic dispersion, and continue to disperse for 2-3 hours until the cloudy liquid becomes a nano-scale suspension, and the production process ends.
Embodiment 2
[0026] The nanometer material composition that is used for the bleaching of cellulose fiber fabric, this composition is made up of following composition by weight ratio:
[0027] Nanoscale silicon dioxide 35 parts
[0028] Sodium hexametaphosphate 22 parts
[0029] 43 parts of ethylene glycol phenyl ether
[0030] The production process of the nanomaterial composition is the same as in Example 1.

Abstract
The invention relates to textile dyeing field in particular to a material composition used for bleaching cellulose fiber fabric, which is prepared from the following ingredients according to the weight part: 35 to 45 of nano-scale silicon dioxide, 10 to 22 of sodium hexametaphosphate and 33 to 55 of ethylene glycol phenyl ether. The process for producing the material composition is as follows: the nano-scale silicon dioxide, the sodium hexametaphosphate and the ethylene glycol phenyl ether are mixed into turbid liquid according to required proportion; the turbid liquid is heated, and an ultrasonic disperser is used for ultrasonic dispersion to change the turbid liquid into nano-scale suspension. The invention has the advantages that with the cooperation of the material composition and caustic soda, the cellulose fiber fabric can be discontinuously bleached by oxydol at high temperature, and the same high-white degree of chlorite-oxidation bleaching by using the sodium chlorite for primary bleaching and using the oxydol for secondary bleaching can be obtained, the production process and the production time can be shortened, a great amount of energy resources, such as water, electricity, steam, and the like, is saved, and the environmental pollution caused by using sodium chlorite for bleaching is avoided.
Description
technical field [0001] The invention relates to the textile printing and dyeing industry, and relates to a material composition for bleaching cellulose fiber fabrics. Background technique [0002] Today, people are increasingly advocating energy saving, environmental protection, and pursuing green and healthy. People are more and more interested in various natural things, and the same is true for the pursuit of textile fabrics. Therefore, the demand for natural cellulose fiber fabrics such as cotton and hemp is also increasing. getting bigger. However, in the processing of such fabrics, in order to achieve higher whiteness requirements, the usual method is to use sodium chlorite for initial bleaching, and then re-bleach with hydrogen peroxide. The production process of this traditional bleaching method is long, the corresponding production time is also long, consumes a lot of energy such as water, electricity, steam, and the use of sodium chlorite bleaching will cause great...
