Embodiment 1
[0055] In this embodiment, textiles are subjected to enzymatic cold-heap treatment by the following method, which specifically includes the following steps:
[0056] (1) Padding biological compound enzyme liquid: pad cotton gray cloth (specification 20×16) in the biological compound enzyme liquid at 40°C, one dipping and one rolling, the liquid retention rate is 100%; Biological compound enzyme solution includes the following components: 1200U / mL α-amylase, 900U / mL cellulase, 10000U / mL xylanase, 800U / mL pectinase, 2g / L calcium chloride, 10g / L preservative agent and 80g / L surfactant, pH6.0~7.0;
[0057] (2) Cold pile at 40°C for 6h;
[0058] (3) Wash 2 times with hot water at a temperature of 70° C., wash 1 time with cold water (i.e. normal temperature water), and then use oxygen bleaching liquid for oxygen bleaching. The oxygen bleaching liquid includes the following components: 10g / L oxygen bleaching aid, 15g / L hydrogen peroxide, 8g / L chelating agent and 2g / L penetrating ag...
Embodiment 2
[0061] In this embodiment, textiles are subjected to enzymatic cold-heap treatment by the following method, which specifically includes the following steps:
[0062] (1) Padding biological compound enzyme liquid: pad cotton gray cloth (specification 20×16) in the biological compound enzyme liquid at 20°C, one dipping and one rolling, the liquid retention rate is 80%; Biological compound enzyme solution includes the following components: 2000U / mL α-amylase, 800U / mL cellulase, 9000U / mL xylanase, 400U / mL pectinase, 8g / L calcium chloride, 15g / L preservative agent and 100g / L surfactant, pH6.0~7.0;
[0063] (2) Cold pile at 20°C for 12h;
[0064] (3) Wash 4 lanes with hot water at a temperature of 80° C., wash 1 lane with cold water, and then use oxygen bleaching liquid for oxygen bleaching. The oxygen bleaching liquid includes the following components: 20g / L oxygen bleaching aid, 5g / L hydrogen peroxide, 10g / L chelating agent and 5g / L penetrating agent, the liquid carrying rate is...
Embodiment 3
[0067] In this embodiment, textiles are subjected to enzymatic cold-heap treatment by the following method, which specifically includes the following steps:
[0068] (1) Padding biological compound enzyme liquid: pad cotton gray cloth (specification 20×16) in the biological compound enzyme liquid at 60°C, one dipping and one rolling, the liquid retention rate is 90%; Biological compound enzyme solution includes the following components: 1500U / mL α-amylase, 1000U / mL cellulase, 12000U / mL xylanase, 1000U / mL pectinase, 5g / L calcium chloride, 5g / L preservative agent and 50g / L surfactant, pH6.0~7.0;
[0069] (2) Cold pile at 30°C for 8h;
[0070] (3) Wash 3 times with hot water at a temperature of 80° C., wash 1 way with cold water, and then use oxygen bleaching liquid for oxygen bleaching. The oxygen bleaching liquid includes the following components: 25g / L oxygen bleaching aid, 10g / L hydrogen peroxide, 2g / L chelating agent and 10g / L penetrating agent, the liquid carrying rate is...
