Description
Technical field
Scouringed and bleaching the present invention relates to a kind of hemp cloth the method for processing, hemp cloth cold pad--batch is first particularly carried out with caustic soda
Processing, then biological treatment is carried out by means of pectase and lignoenzyme etc., oxidation bleaching is finally carried out, realizes that hemp cloth is scouringed and bleaching
The method of processing, belongs to textile chemistry and biological technical field.
Background technology
Hemp belongs to native cellulose fibre, has the Optimalities such as thin, the ventilative, bacteria mildew-proof of moisture absorption of fibre fineness
Energy.Hemp can be with cotton, hair and chemical fibre blending or intertexture, and gained fabric texture is carefully thin, outward appearance is well-pressed, feel is fine and smooth, strong
It is durable, it is deep to be favored by domestic and international consumer.
In hemp structure in addition to main cellulose portion, the impurity such as pectic substance, hemicellulose and lignin contains
Amount is higher.The flaxen fiber that pectin enables single fiber length shorter in hemp is mutually bonded together, and has yarn certain
Strongly；Content of lignin is higher in fiber, and some is up to 10% or so, and lignin is not only to hemp outward appearance, gloss, feel
Have an impact, fiber spinnability and dyeability are influenceed also larger.Therefore, weaving should be removed in the pre-treatment of hemp product
The slurry of middle addition, hydrophobic contaminants in hemp are also removed, and moderately retain certain residual silkgum content, put down with obtaining outward appearance
Whole, the preferable hemp fabric of strength.Hemp cloth pre-treatment at present mainly uses caustic soda as refining agent, under high temperature basic conditions
Carry out, the scattered and emulsification of mating surface activating agent makes hydrophobic contaminants in fiber fully be removed.Though high temperature alkaline process
Right dust removal rate is higher, but control it is improper be easier to that hemp is caused to damage, if big flax bunch fiber is fully dissociated into processing
Single fiber state, not only filoplume increases on fabric, and the strength of fibre can also occur significantly to decline.Compared with alkaline process,
Biological enzyme pre-treatment has the advantages of efficient, single-minded, low energy consumption and of low pollution.Efficient scouring enzyme is to slurry in fibre
And non-fiber commensal have remove effect enzyme preparation general name, including amylase, pectase, cellulase, lignoenzyme and
Protease etc..Higher in view of pectic substance in hemp and content of lignin, pectase and lignoenzyme are in hemp is processed
With potential application effect.Pectase can be broken pectin macromolecular chain in flaxen fiber, and impurity complexes are loosely organized, improve fiber crops
Yarn feel and fabric drapability；Lignoenzyme can the organic compound such as lignin degrading and polycyclic aromatic hydrocarbon, improve flaxen fiber outside
Sight and hydrophily.
The characteristics of according to strength damage easily occurs in hemp impurity content height and alkaline process kiering, it is considered as alkaline process and life
The method that thing enzyme is combined carries out hemp cloth pre-treatment.First bank up processing under cryogenic with alkaline process, enter again through hot water wash
Row enzyme process is refined, and not only can effectively go the removal of impurity, and strength can be avoided significantly to decline, and the dyeing and finishing for meeting energy-conservation and environmental protection adds
Work requirement.
The content of the invention
The purpose of the present invention aims to provide a kind of hemp cloth and scouringed and bleaching the method for processing, using the present invention compared with traditional soda before
Energy-saving, mitigation environmental pollution is handled, reduces fibre damage.
Technical scheme：A kind of hemp cloth is scouringed and bleaching the method for processing, it is characterized in that using caustic soda and bleeding agent
Hemp cloth cold-pad-batch preparation is carried out, the biological treatments such as pectase, lignoenzyme is carried out again after hot water wash, finally carries out oxygen
Change bleaching, realize the hemp cloth dyeing and finishing pre-treatment processing based on energy-conserving and environment-protective.
Concrete technology step is as follows：
(1) cold pad--batch is handled：The white silk liquid formed with caustic soda, bleeding agent etc. is carried out hemp cloth and pads processing, banks up regulation
Hot water wash is carried out after time；
Bank up process conditions：0.2~20g/L of NaOH, 0~10g/L of bleeding agent, liquid carrying rate 70~150%, bank up temperature
10~30 DEG C, bank up 1~36h of time.Bank up to the stipulated time, with the abundant washing of 50~100 DEG C of hot water 1~5 time.
(2) enzyme pre-treatment is refined：Through step (1) processing after hemp cloth the compositions such as pectase, lignoenzyme enzyme
Handled in liquid；
Enzyme treatment process condition：0.01~10g/L of pectase, 0.01~10g/L of lignoenzyme, 0~10g/ of cellulase
L, 20~60 DEG C of temperature, 30~240min of processing time, bath raio 1:5~100.It is fully net with 50~100 DEG C of hot water after ferment treatment
Wash 1~2 time.
(3) oxidation bleaching：Hemp cloth after step (2) processing is bleached with hydrogen peroxide, further removes hemp
The a small amount of pigment remained in fabric and non-fiber commensal.
Oxidation process conditions：0.5~5g/L of NaOH, H2O2(30%) 0.5~20g/L, 0.5~10g/L of hydrogen peroxide bleaching stabilizer,
80~100 DEG C, 15~120min of processing time of temperature, bath raio 1:5~100.
(4) enzyme process deoxygenation：Hemp cloth after step (3) processing carries out deoxygenation with catalase；
Deoxyprocess condition：20~60 DEG C, 10~60min of processing time of 0.01~10g/L of catalase, temperature, bath
Than 1:5~100.With the abundant washing of 50~100 DEG C of hot water 1~2 time after ferment treatment.
A kind of hemp cloth is scouringed and bleaching the method for processing, be applicable the hemp product of processing include pure spinning or with cotton, wash
Knitted fabric and woven fabric of fiber blend etc.；The pectase, lignoenzyme and fiber of separate sources can be added in cellulase treatment
Plain enzyme is combined processing, and pad steaming process can be also used in addition to using infusion process processing；Oxidation bleaching and enzyme process deoxygenation can be according to fibres
Fiber products pool selection to be dyed determines that the dark kind in part can be without peroxide bleaching and enzyme process deoxygenation.
Beneficial effects of the present invention：
(1) fibre high treating effect.Banked up by rolling alkali and hot water wash, remove most of impurity in hemp,
The pectic substance of residual and lignin portion are removed with pectase and lignoenzyme etc. on the basis of this, not only makes fibre whiteness
Increase, hydrophily lifting, and the drawbacks of easily caused fiber filoplume of traditional soda increases and strongly declined is avoided, with this hair
The fibre cloth cover of the bright method processing addressed is smooth, and strength damage is small.
(2) dyeing course energy-saving and emission-reduction.Pre-processed using caustic soda cold pad--batch, with reference to cellulase treatment under middle cryogenic conditions,
The energy consumption in production is not only reduced, and the impurity such as pectic substance, lignin are hydrolyzed by means of biology enzyme for processing, may be used also
Realization cleans dyeing and finishing production, alleviates environmental pollution.
