Embodiment 1

[0014] The seaweed fiber fabric to be treated is produced by German ZIMMER company. The fabric structure is: cotton and tencel blended, tencel fibers contain 15% seaweed fibers plus silver ions. The tissue specification is: C75 / TEN25 (seaweed+silver) 50×50+40D80×8673″.

[0015] The pretreatment process is:

[0016] Add water to the water tank, heat the water to 52°C, put the seaweed fiber fabric into the heated water, add 2.5g of desizing enzyme 301L, 1.7g of penetrant CWA, and 2.5g of cooking agent 88ECO per liter of water, Add desizing enzyme 301L, penetrating agent CWA, and cooking agent 88ECO into water and mix them evenly to form a treatment solution. Raise the temperature of the treatment solution to 88°C, transfer the seaweed fiber fabric to the above treatment solution for 16 passes, and then put the treatment in the water tank liquid discharge;

[0017] Then add water to the water tank, raise the temperature of the water to 95°C, put the seaweed fiber fabric treate...

Abstract

The invention provides a preliminary treatment technology of a seaweed fiber fabric, which belongs to the processing technology in the printing and dyeing production field of the textile. The technology includes the following steps: adding water in a water tank, placing the seaweed fiber fabric into the water which is heated, adding 301L nerbanase, penetrant CWA and Kier boiling agent 88ECO into the water and evenly mixing the mixture to form treating fluid, rotating the seaweed fiber fabric in the treating fluid for 15-17 circles, then draining the treating fluid from the water tank, adding water into the water tank for a plurality of times, and placing the seaweed fiber fabric into the water which is heated for a plurality of times for processing so as to finish the pre-treatment process. The treated seaweed fiber fabric can reach the desizing grade requirement of semi-finished seaweed fiber fabrics, and the metal cations and alginate in the seaweed fiber fabrics can not be lost and the physical property or the physical index can not be destroyed during the subsequent dyeing and finishing process; good dyeing or bleaching effect can be obtained in the next dyeing and finishing process if the process is complete.

Description

technical field [0001] The invention relates to a processing technology in the field of textile printing and dyeing production, in particular to a pretreatment technology of seaweed fiber fabric. Background technique [0002] Seaweed fibers are usually prepared by wet spinning, that is, soluble alginate is dissolved in water to form a viscous solution, which is then extruded through a spinneret into a coagulation bath containing divalent metal cations to form solid insoluble alginate fiber filaments . At present, the research on seaweed fiber by various scientific research institutions in the world is mainly its application in medical care. For example, US Patent No. 4393048 describes a non-fibrous seaweed wound covering material, which contains water-soluble alginic acid. Salt can keep the wound moist all the time; Swedish patent No. 424956 introduces a water-insoluble alginate hydrogel wound covering material, which can also avoid the problem of dryness of the wound.
