Description
Technical field
The present invention relates to the continuous destarch of a kind of all cotton woven fabric biology enzyme, concise single bath process pre-treatment process, belong to all cotton woven fabric pre-treatment process technical field of dyeing.
Background technology
Grade natural impurity or claim accompaniment of the ash that contains protein, the 0.7-1.6% of wax, the 1.0-1.9% of pectic substance, the 0.4-1.2% of 0.4-1.2% on the cotton fiber, these impurity mainly are present in the cuticula and primary cell wall of cotton fiber.Owing to the needs of weaving process, warp thread will carry out starching, brings additional impurities on the fabric so in addition---and slurry has PVA, starch slurry etc.The existence of these impurity has had a strong impact on the wettability of cotton fiber, makes cotton fiber have hydrophobicity, and has had influence on performances such as the dyeing of cotton fiber, back arrangement.So the first step of cotton textile dyeing and finishing processing is to carry out pre-treatment, the slurry on the COTTON FABRIC, the removals such as natural impurity on the fiber, improve wetting, the permeance property of COTTON FABRIC, for good condition is created in follow-up dyeing, back arrangement.
The pre-treatment of all cotton woven fabric is main at present adopts caustic soda and surfactant to carry out destarch, concise, Piao Bai mode again, utilize the expansion of caustic soda to the COTTON FABRIC spreading mass, carry out destarch with a large amount of hot water injections again and utilize caustic soda impurity such as lyophobic dust on the cotton fiber to be removed in effects such as the emulsification of the middle-and-high-ranking fatty alcohol of wax, higher fatty acids and hydrocarbon, dispersion, improve wettability to the decomposition of pectic substance, protein and to the saponification of fatty acid ester material in the wax and surfactant.This technology has reasonable pre-treatment effect, but also has many problems simultaneously.This processing mode cotton wax clearance is higher, reaches more than 70%, has influenced the feel of COTTON FABRIC; In addition, owing to handle under high temperature highly basic condition, the damage of cotton fiber is also bigger; Even more serious is, the chroma in waste water height of highly basic destarch, kiering, alkalescence is strong, the pH value reaches more than 12, the COD value is up to more than the 10000ppm, severe contamination ecological environment, also to consume a large amount of water, electric equal energy source in addition.
The pre-treatment of biology enzyme COTTON FABRIC is owing to utilized the mildness of selectivity, high efficiency and the treatment conditions of biology enzyme height, basically under nearly neutrallty condition, handle, so the damage to fiber is little, the colourity of handling waste water is low, the pH value is near neutral, and the significantly reduction of COD value, and original 1/3-1/5 is only arranged, significantly alleviated pollution, had important social, economic worth environment.
Summary of the invention
The objective of the invention is to seek the continuous destarch of a kind of all cotton woven fabric biology enzyme, concise single bath process pre-treatment process, utilize biotechnology to carry out the production that cleans of cotton pretreatment, promptly utilize biology enzyme to carry out the destarch, concise of the traditional high temperature highly basic of destarch, concise replacement, and reach its effect.
The continuous destarch of a kind of all cotton woven fabric biology enzyme, concise single bath process pre-treatment process, all cotton woven fabric elder generation is through the hot water preliminary treatment, through padding the biology enzyme processing of biology enzyme, decatize, enzyme goes out, washing, handle through padding the bleaching of hydrogen peroxide, decatize again, wash each operation and finish the pre-treatment of cotton fabrics.
The woven grey cloth of cotton: this technology is applicable to the woven grey cloth of cotton, as poplin cloth, yarn card, canvas etc.
The hot water preliminary treatment comprises and soaks one cold water (normal temperature), two road hot water (more than 90 ℃): this operation has important function to destarch, the scouring result that guarantees the biology enzyme pre-treatment, especially to the PVA chemical sizwe.
Biology enzyme is handled, and comprises and pads enzyme treatment fluid, decatize: be the key that guarantees treatment effect, need careful kind and the treatment conditions of selecting enzyme.The enzyme that the present invention selects is wide temperature width of cloth destarch enzyme, middle temperature pectase.
Pad the enzyme treatment fluid: the consisting of of enzyme treatment fluid, destarch enzyme 0.2-10 grams per liter, pectase 0.1-5 grams per liter, non-ionic surface active agent or weak anionic surfactant are wetting, bleeding agent 0-10 grams per liter, pH5.5-10, liquid carrying rate 50%-120%.
Decatize: decatize also is the key factor that influences the enzyme treatment effect, and steam temperature is too high, though the enzyme processing speed is very fast, can influence the vigor of enzyme, and steam temperature is low excessively, though the loss of the vigor of enzyme is less, also can influence treatment effect.The steam temperature that the present invention adopts is 50-90 ℃, steaming time 30-80 minute.
Enzyme goes out: the enzyme that goes out can adopt and improve the pH value or improve temperature to the 80-105 ℃ of method of handling 10-20 minute.
Washing: it is clean fully to wash the Impurity removal that helps bio-enzyme degradation is got off.
Hydrogen peroxide bleaching is handled, and comprises and pads bleaching liquid, decatize: this operation has important function to whiteness, the wettability that guarantees the pre-treatment semi-products.
Pad hydrogen peroxide bleaching liquid: the consisting of of bleaching liquid, 100% hydrogen peroxide 5-15 grams per liter, sodium metasilicate 10-60 grams per liter, pH10-13, liquid carrying rate 50%-120%, non-ionic surface active agent or anion surfactant are wetting, bleeding agent 0-15 grams per liter.
Decatize: decatize is the important means that reaches the hydrogen peroxide bleaching effect, and the decatize condition kicks the beam can influence bleaching effect.In general, the steam temperature height, the time can lack, and steam temperature is low, and the time should be grown.The decatize condition that the present invention adopts is, steam temperature 80-105 ℃, and steaming time 30-80 minute.
The novel pre-treatment process that the present invention adopts biology enzyme to replace caustic soda to carry out COTTON FABRIC destarch kiering, the biology enzyme that is adopted has adopted amylase, pectase in handling.Adopt pretreatment Process of Cotton Fabrics Using Enzymes of the present invention to have pre-treatment effect preferably.Handle noresidue slurry, noresidue cotton seed hulls on the fabric of back, whiteness reaches the level of alkali treatment, through the capillary effect after 105 ℃ of oven dry more than 9.0 cm per minute.Technology of the present invention in addition is little to fibre damage; handle the quality height of fabric, soft, the colourity of PROCESS FOR TREATMENT waste water particularly of the present invention, pH value, COD value are far below traditional handicraft; be very beneficial for the protection of ecological environment, also alleviated the burden of sewage disposal greatly.And the present invention pads the continuous processing technique of decatize owing to adopted to move back and boil a bath, has the production efficiency height, labour intensity is low, characteristics such as energy-conservation, water saving.
