Abstract
The invention discloses an oxidizing, bathing and low-temperature bleaching process for fiber pretreatment enzyme, which comprises the following steps: dissolving 1 to 2 grams per liter of osmotic agent in a treatment bath at a temperature of between 20 and 30 DEG C, putting textile into the treatment bath, and keeping the treatment bath flowing evenly and circularly; heating the temperature to 55 DEG C, adding 1 gram per liter of biological refining enzyme and 3 grams per liter of hydrogen peroxide into the treatment bath, adjusting the pH to be 7 to 9, and processing the treatment bath for 40 minutes; and heating the temperature to 80 DEG C, adding 3 grams per liter of low-temperature bleaching agent, treating the treatment bath at the temperature, then water washing, and entering the following processes. The process achieves low-temperature refining and low-temperature bleaching, and reaches the aim of low-temperature, environment-friendly, energy-saving and efficient preliminary treatment.
Description
Technical field
The present invention relates to a kind of fiber pre-treatment process, especially a kind of enzyme oxygen one is bathed---and the cold bleaching pre-treatment process belongs to textile technology field.
Background technology
At present, textile industry adopts traditional chemical Degumming and dyeing and printing process more, relies on strong acid, highly basic that linen-cotton is handled, strong chemical action has been destroyed the fibre structure of textiles when removing the fiber commensal, make fibre strength impaired, spinnability is poor, and row yielding is low.On the other hand, the industrial chemicals and the energy such as a large amount of acid of chemical technology method consumption, alkali, institute's effluent basicity height, color and luster is dark, BOD is high, COD is high especially, has caused the serious environmental pollution.
Along with the continuous enhancing of people's environmental consciousness, green weaving and environment-protective process have become the important foundation of textile industry sustainable development.Only require the idea of end treatment before the idea of the omnidistance environmental protection of people now will thoroughly change, and enzyme preparation is as a kind of efficient, single-minded, biocatalyst with environment compatibility, its application in textile industry also will more become extensive thereupon.The treatment process that the biorefining enzyme is used for fabric such as linen-cotton is exactly one of research focus wherein, and it not only reduces environmental pollution, and saves a large amount of process waters in technical process.Chinese patent 021485275 discloses a kind of cotton or has washed/cotton fabrics oxidation dipping biology enzyme dipping batch process pre-treatment process, adopt knitted fabric to carry out the preliminary treatment of hydrogen peroxide dipping earlier, washing carries out that the biology enzyme maceration enzyme is handled, enzyme goes out again, washing, batch process is finished the pre-treatment of knitted fabric.2003101060232 disclose the continuous destarch of a kind of all cotton woven fabric biology enzyme, concise-bath method pre-treatment process, adopt the hot water preliminary treatment of all cotton woven fabric elder generation, through padding biology enzyme destarch, the refining processing of biology enzyme liquid, decatize, washing, handle operation such as washing and finish the pre-treatment of all-cotton fabric again through the bleaching of padding hydrogen peroxide bleaching liquid, decatize.
Although the pre-treatment of biorefining enzyme is through many-sided application test, present most of factories only optionally are applied in indivedual dark kinds, on using certain limitation are arranged.And in follow-up dyeing course,, need draw a design again and cause laboratory personnel's work load, so factory accepts to acquire a certain degree of difficulty owing to the difference on coloured light and the traditional handicraft.
Summary of the invention
For solving the deficiency that prior art exists, technical problem to be solved by this invention is to provide a kind of fiber pre-treatment enzyme oxygen one bath---cold bleaching technology, realize the concise and cold bleaching of low temperature, and reach low temperature, environmental protection, energy-conservation, pre-treatment target efficiently.
For solving above-mentioned technical problem, the technical scheme that the present invention takes is that a kind of fiber pre-treatment enzyme oxygen one is bathed---cold bleaching technology, and it comprises following content:
1, bleeding agent is dissolved in 20-30 ℃ by 1-2g/L and handles bath, with the textiles input wherein, keep handling bathing evenly circulating;
2, be warming up to 55 ℃, the consumption of pressing 1g/L biorefining enzyme, 3g/L hydrogen peroxide adds to be handled in the bath, and adjusting PH is 7-9, handles 40min;
3, be warming up to 80 ℃ again, add the agent of 3g/L cold bleaching, handle 20min under this temperature, washing enters following operation then.
Above-mentioned fiber pre-treatment enzyme oxygen one is bathed---and cold bleaching technology, its step 1 is handled in the bath for bleeding agent is dissolved in 30 ℃ by 2g/L.
Above-mentioned fiber pre-treatment enzyme oxygen one is bathed---and cold bleaching technology, it adjusts PH is 9.
Technology of the present invention, utilize the refining enzyme product KDN---01B of Qingdao Continent Biotech Co., Ltd. can tolerate this characteristic of high concentration hydrogen peroxide, the synergy of and hydrogen peroxide concise by enzyme, realize the concise and cold bleaching of low temperature down the auxiliary of cold bleaching agent, finally reach low temperature, environmental protection, energy-conservation, pre-treatment target efficiently.It has, and pre-treatment is effective, and destarch is effective, the whiteness height; wettability is good; little to fibre damage, handle the quality height of back fabric, characteristics such as soft; and handle the colourity of waste water; the pH value, the COD value is lower than traditional handicraft, can alleviate the burden of sewage disposal; help ecological environmental protection, also have advantages such as production efficiency height, labour intensity are low, energy-conservation, water saving.
The refining enzyme product KDN---01B that refining enzyme KDN---01B used in the present invention is Qingdao Continent Biotech Co., Ltd. can buy from market.
Other raw materials involved in the present invention are the usual product that uses of the industry.
