Abstract
A special refined composite enzyme for boiling and bleaching and fabric pre-treatment are disclosed. The composite enzyme consists of alpha-amylase 30 wt%, composite cellulase 50 wt%, pankrin 10 wt% and lipolytic enzyme 10 wt%. The process is carried out by pre-treating for household fabrics, de-starching, digesting, bleaching at 50-60 degree and pH=5.0-7.5 in proportion of 1:12-15 for 30-60 mins, injecting water while adding into refined composite enzyme 0.8-1.2 wt% with temperature lower than 40 degree, opening machine, circulating for 5 mins, raising temperature to 50-60 degree, keeping temperature for 30-60 mins, adding into stabilizer 3-5g/L and H202 (100%) 6-8L, raising temperature above 98 degree, keeping temperature for 60 mins, discharging water, washing by hot water, washing by cold water and after-treating.
Description
Technical field:
The present invention relates to bioengineering field, belong to the textile printing and dyeing technology, particularly a kind of weaving and knitting pretreatment " boiling, bleaching-bathing " special composite enzyme for refining and application thereof
Background technology:
At present, in textile printing and dyeing industry, what textiles and knitting pretreatment were taked is method boiling-off of high temperature alkali oxygen and bleaching, and this method energy consumption height, pollution are greatly.Because this method is to adopt to burn alkali and hydrogen peroxide boiling-off and bleaching water-bath segmentation technology under the high temperature bath state, the mode of production falls behind, and workman's production environment is abominable, labour intensity is big, product specification is low, energy consumption is big and serious pollution of water environment." boiling, bleaching-bathing " special composite enzyme for refining: (1) acts in the warm water that is lower than 60 degree, reduces the intensity of energy consumption and workman work.Utilize the synergy of plurality of enzymes systems such as amylase, compound circumscribed cellulase, endo cellulase, hemicellulase, proteolytic enzyme, lipase, pectin depolymerizing enzyme, pectinesterase to reach destarch, boiling-off, bleaching process requirement at the state of gentleness.(2) utilize special composite enzyme for refining to the branch segment process that household textiles and knit fabric carry out pre-treatment destarch, boiling-off, bleaching, be combined into a procedure.The boiling, bleaching-bathing special composite enzyme for refining makes to boil and floats to such an extent that water yield reduces sauce or the remaining slurry that (3) special composite enzyme for refining more than 50% can effectively be removed fabric face; Can remove the fento of fabric face, prevent fibrillation: can remove the central impurity such as ash, wax, pectin substance and oxygen carrier of fabric, improve the loft and the water-absorbent of fabric; Can promote the shape generation fundamental shifts of natural fiber, the fibrous inside molecular assembly is arranged, make fabric face become smooth submissive, the tension that effectively improves fabric how latter stage intensity.Thereby reach biopolishing, decrement, softness, bulk, the good result of suction and good dyeing, fixation function, the product that adopts special composite enzyme for refining to handle is compared with traditional alkali oxygen method treatment effect and can be improved surface smoothness and persistent soft function, promotes the product quality class.(4) special composite enzyme for refining can realize not having soda acid destarch, boiling-off, bleaching in pre-treating technology: the use of saving softening agent in the back arrangement process, make factory or else change existing technology and do not increase substantially under the prerequisite of cost, the effect of replacing acid, alkali and chemical assistant has reduced sewage disposal difficulty and processing costs.(5) working conditions: PH:5.0-7.5 temperature; 50---60 times: 30---60 minutes bath raioes: 1: 12---15 refining prozyme consumptions: 0.8---1.2% (dry fabric weight relatively) addings: when dying the machine water filling, add (the dilution temperature should not surpass 40).With common cotton towel pre-treating technology is reference: towel is washed in advance---dye the machine water filling, add prozyme (water temperature is no more than 40 and is advisable),---machine circulation after 5 minutes, persistently overheating 50---60 and be incubated 30---60 minutes---add stablizer 3---5g/L and H2O2 (100%) 6_---8g/L, persistently overheating more than 98 and be incubated 60 minutes------hot water wash---cold wash---is carried out later process in draining.
