Embodiment 1

[0059] This embodiment adopts hydrosulfite (Na 2 S 2 o 4 ) light quantum low-temperature triggering impregnation catalytic stripping method to carry out sand washing treatment to denim, and the sand washing treatment liquid consists of 2.00g / L hydrosulfite (Na 2 S 2 o 4 ) aqueous solution, and adjust the pH to 4.0; then add it to the reaction device at a bath ratio of 1:50.

[0060] The reaction device used in this embodiment is a batch reaction device. See attached figure 1 , the batch type glass reactor 2 holds the sand washing treatment solution, in the batch type glass reactor 2, an oxygen increasing device 8 is installed, and an oxygen increasing pump is used to continuously feed air into the sand washing treatment solution through the oxygen increasing device 8; The center of the batch glass reactor 2 is provided with a quartz glass tube 5 and a low-pressure ultraviolet mercury lamp 6, and the outer part of the quartz glass tube 5 is provided with a ring-shaped ult...

Embodiment 2

[0065] This embodiment adopts hydrosulfite (Na 2 S 2 o 4 ) light quantum low-temperature trigger dipping catalytic stripping method to carry out sand washing process on denim, prepare sand washing treatment liquid containing 2.00g / L insurance powder by a bath ratio of 1:50, adjust pH to 4.0, pour sand washing liquid into embodiment 1 in the reaction device, and then place the denim flat on the attached figure 1 On the periphery of the middle quartz sleeve 5, turn on the ultrasonic processor, and according to the method of embodiment 1, carry out intermittent sand washing treatment on the denim sample at room temperature (25° C.) for 90 min. The specific steps and other conditions are as described in embodiment 1. stated.

[0066] Table 2 shows the experimental results of sand-washing denim samples using the method described in this example. As can be seen from Table 2, using hydrosulfite (Na 2 S 2 o 4 ) light quantum low-temperature trigger padding catalytic stripping m...

Embodiment 3

[0070] The present embodiment adopts potassium persulfate (K 2 S 2 o 8 ) light quantum low temperature triggers the impregnation catalytic stripping method to carry out sand washing process to denim, and the sand washing treatment liquid is potassium persulfate (K) of 2.00g / L 2 S 2 o 8 ) aqueous solution, adjust the pH of the solution to 3.0, pour the sand washing solution into the reaction device in Example 1, and then place the denim sample flatly on the attached figure 1 On the periphery of the middle quartz sleeve 5, turn on the ultrasonic processor, and according to the method of embodiment 1, carry out intermittent sand washing treatment on the denim sample at room temperature (25° C.) for 90 min. The specific steps and other conditions are as described in embodiment 1. stated.

[0071] Table 3 shows the experimental results of sand washing the denim samples using the method described in this example. It can be seen from Table 3 that under the photon stripping cond...

Abstract

The invention relates to a jean sand-washing method based on a light quantum stripping system. Sand washing of jean is realized by taking highly-oxidative or reductive high-energy active substance generated by light quantum low-temperature induced photosensitive substance and a sand washing aid as sand washing agents and combing with ultrasonic effect of ultrasonic waves to enable the jean to havefading effect and old-fashioned sense different in degree. Light quantum system stripping sand-washing technology is adopted, so that chemical products like sand blast, alkaline aids and oxidizers harmful to human body and environment are not needed; ultrasonic enhanced technology is adopted, so that process time and flow are shortened greatly, and water resource consumption and emission of a lotof wastewater are reduced. The method has the remarkable advantages of energy conservation, consumption reduction, emission reduction, simple equipment and process, convenience in operation, cleanliness and environment friendliness and has quite wide application prospect in the aspect of realizing ecological and environment-friendly jean sand-washing.

Description

technical field [0001] The invention relates to the technical field of textile dyeing and finishing, in particular to a denim sand washing method based on an optical quantum stripping system. Background technique [0002] Denim has been around since the invention of jeans. In order to meet people's aesthetic pursuit, denim garment manufacturers usually use industrial washing technology, that is, through various processing methods, to make new trousers produce an "old" effect. This industrial washing technology is called "water washing", in which sand washing is an important means in water washing processing. Sand washing often uses some alkaline and oxidative additives to make the clothes have a certain fading effect and old feeling after washing. If it is equipped with a stone mill, a layer of soft frosty white fluff will be produced on the surface of the cloth after washing, and then add some soft It can make the fabric soft and soft after washing, so as to improve the c...
