【 Characteristics 】

Scouring enzyme CB - 98 is a kind of enzyme technology and chemicals with the combination of high-tech environmental protection products, mainly applied to cotton yarn, cotton fabric in dyeing pretreatment before bleaching process. It represents the traditional cooking back bleaching three-step process of caustic soda, scouring agent, oxygen bleaching stabilizer and other additives. After practice one bath bleaching processing, can effectively remove the fabric on the cotton seed shellis impurities, waxy,, slurry, pigments, etc, make the fabric surface is smooth, soft and smooth; And the hydrophilicity were significantly increased, water absorption and diffusion degree, can increase chromatically rate and levelness of dyeing process. Is particularly important for energy conservation and emissions reduction, to reduce the production cost and improve the production efficiency will play a role.

【 Application 】

(such as singeing wet cloth, can pad new super wide temperature of desizing enzyme CB - 2000 - L 1 ~ 3 g/L, efficient penetrating agent GB - GS (ionic) 1 ~ 2 g/L, one-step practice drift into cloth increased 2 ~ 3, 80 ~ 95 ℃ hot water to wash. Semi-product desizing and feel better.

Note: different concentration process can be adjusted according to the fabric situation.

2, alkali heap, woven cotton cloth pad steaming shows two step process

(1) basic heap: recycling weak alkali mercerizing 30 ~ 50 g/L; 980 j penetration scouring agent 3 ~ 5 g/L. Two dip two rolling, rolling fluid rate 100%; Pad temperature: 60 ~ 80 ℃; Bandaging rotational piled: summer 6 ~ 12 h, winter 12 ~ 24 h.

(2) one bath pad steaming shows: scouring enzyme CB - 98-20 ~ 30 g/L, drift spirit CB - ZP help 10 ~ 20 g/L; 100% H2O2 8 ~ 15 g/L. Wet cloth (alkali heap) - > 2 ~ 4 cell before hot water washing (80 ~ 95 ℃) - > after 1 ~ 2 cell rolling material (room temperature) - > steaming: 100 ℃ (45 ~ 60 min - > hot water to wash the 4 ~ 6 cell (90 ~ 95 ℃) and drying.

Note: is suitable for the cotton seed shellis Mao Xiao demanding, remove the strict, desizing dye varieties.

3, woven cotton cold heap, alkali cooking or one bath shows two steps process

(1) cold heap: scouring enzyme CB - 98 for 20 ~ 30 g/L, and help the floating spirit CB - ZP 10 ~ 20 g/L; 100% H2O2 8 ~ 15 g/L. Two dip two rolling, rolling fluid rate 100%; Pad temperature: room temperature; Bandaging rotational piled: summer 16 ~ 18 h,

Winter 22 ~ 24 h.

(2) the soda boiling (or one bath shows)

① alkali cooking: 100% NaOH 20 ~ 40 g/L; 980 j penetrating scouring agent 4 ~ 6 g/L. Effective chelating agent 0.5 ~ 1 g/L.

Practice drift: ② one bath scouring enzyme CB - 98 5 ~ 10 g/L, and help the floating spirit CB - ZP 4 ~ 8 g/L; 100% H2O2 for 3 ~ 6 g/L.

Cold wet cloth (heap) 2 ~ 4 cell before and after hot water washing (80 ~ 95 ℃) and 1 ~ 2 cell rolling material (room temperature) - > steaming: 100 ℃ (45 ~ 60 min - > hot water to wash the 4 ~ 6 cell (90 ~ 95 ℃) and drying.

Note: soda boiling are suitable for dyeing in the dark fabric; A bath method shows is suitable for light color or bleached fabric.

4, woven cotton cloth jigger practice bleaching process

Formula (for fabric weight O.W.F) : scouring enzyme CB - 98 2.5 ~ 3.5%; 100% H2O2 0.5 ~ 1.0%; Chelating dispersant 0.1 ~ 0.3%. Dry cloth, hot water washing (80 ~ 90 ℃) 2 way to practice drift (60 ~ 70 ℃) 2 the tao (above 95 ℃) 6 ~ 12 - hot water washing (90 ~ 95 ℃) 4 ~ 6, hot water washing (80 ~ 90 ℃) 2 ~ 4 - cold water wash, out of the cylinder.

5, knitting cotton one bath bleaching process practice (bath ratio: 1:12 ~ 15)

Bleaching knitting formula: bath in the treasure of 2 g/L; Scouring enzyme CB - 98 2 ~ 6 g/L; 100% H2O2 1 ~ 3 g/L; To 0.5 g/L oil spirit; Cotton with a whitening agent x g/L. Overflow tank operation: first, in the specified amount of water added bath treasure up to 40 ℃ into cloth, then slowly add cotton with a bleaching agent, and continue to heat up to 50 ℃ after joining scouring enzyme CB - 98, adding hydrogen peroxide when temperature 60 ℃, 80 ℃ when joined to the oil spirit; Temperature scouring 50 min at 98 ℃ heat preservation; Scouring over hot water to wash again (if you need pickling: 1 g/L additive glacial acetic acid; 80 ℃ by 20 min), cold water washing out of the cylinder.

6, cotton towel is fabric one bath bleaching process

(1) one bath slack rope can practice cooking cloth bleaching process (bath ratio: 1 to 6) : recipe: scouring enzyme CB - 98 5 ~ 15 g/L, drift CB - ZP help 4 ~ 6 g/L; 100% H2O2 for 2 ~ 6 g/L. Shows: 100 ℃ x 50 ~ 80 min; Hot water washing with traditional process. (practice bleaching and whitening can be a bath).
