Technical field
The present invention relates to the knitted fabric pre-treatment process field of dyeing, particularly relate to a kind of pure cotton fabric bioenzyme pretreatment technology.
Background technology
Contain 0.4 ~ 1.2% pectic substance, 0.4 ~ 1.2% wax, 1.0 ~ 1.9% protein, 0.7 ~ 1.6% the ash natural impurity that grades on the cotton fiber, these impurity mainly are present in the cuticula and primary cell wall of cotton fiber.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, removes the natural impurity on the cotton fiber, improves wetting, the permeance property of COTTON FABRIC, create good condition to follow-up dyeing and back arrangement.
The present pre-treatment of all-cotton fabric is under the highly basic condition, to carry out; Main employing caustic soda and surfactant kiering, the mode of bleaching again; Utilize caustic soda the 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 pre-treatment effect preferably, but needs to consume significant amount of energy, water and chemical reagent, and the chroma in waste water of highly basic kiering is high, alkalescence is strong, the COD value is high, is unfavorable for environmental protection.
In recent years, along with development of biology, the application of enzyme in weaving more and more receives people's attention.It is very possible utilizing high efficiency, selectivity and the gentle reaction condition of enzyme to replace the pre-treatment of high temperature highly basic.To the kind of existing commercial enzyme, the destarch kiering of COTTON FABRIC can select for use biology enzyme to carry out, and bleaching still needs hydrogen peroxide.But because the limitation of existing enzyme; The effect of carrying out oxidation bleaching at present in the pre-treatment process of all-cotton fabric after the first compound bio enzyme desizing kiering is not very desirable; Have that hygroscopicity of fabric is bad, whiteness is not high, wettability is bad, the relatively poor shortcoming of polyvinyl alcohol (PVA) slurry removal effect.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of pure cotton fabric bioenzyme pretreatment technology; Can improve the accessibility of enzyme; Help giving full play to of enzyme effect, improve wettability of fabrics and whiteness, and strengthened the removal effect of polyvinyl alcohol (PVA) slurry.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of pure cotton fabric bioenzyme pretreatment technology is provided; Its technological process comprises: the grey cloth of singing, preliminary treatment, oxidation bleaching, washing, compound bio enzyme desizing kiering, washing and drying; Said oxidation bleaching flow process helped giving full play to of compound biological enzyme effect before compound bio enzyme desizing kiering flow process.
In preferred embodiment of the present invention, said preliminary treatment comprises: cold water preliminary treatment 1 road and 90 ℃ of hot water preliminary treatment 2 roads, and K2S2O8 (potassium peroxydisulfate) and bleeding agent DX-2 bath raio are 1:20 in 90 ℃ of hot water preliminary treatment, the time is 3min.
In preferred embodiment of the present invention, said oxidation bleaching: 100% hydrogen peroxide solution 5g/l, waterglass 8g/l, K2S2O8, DX-2 are 10g/l, pick-up 50%, 98 ℃ of steam temperatures, pretreatment time 60min, pH value are 11.
In preferred embodiment of the present invention, said washing: wash 4 roads in 90 ℃ of hot water.
In preferred embodiment of the present invention, said compound bio enzyme desizing kiering: biology enzyme (L-2000) 1.5g/l, pectase 1.5g/l, cellulase 1.5g/l, DX-2 are 10 g/l, pick-up 50%, 65 ℃ of steam temperatures, time 60min, pH value 8.5.
In preferred embodiment of the present invention, said drying: under 105 ℃ of temperature, drying by the fire 2h, is balance 24h under 65% the constant temperature in 20 ℃ of temperature, relative humidity again.
The invention has the beneficial effects as follows: the present invention is placed on the oxidation bleaching flow process before the complex enzyme destarch kiering; Can improve the accessibility of enzyme; Help giving full play to of enzyme effect, improve wettability of fabrics and whiteness, and strengthened the removal effect of polyvinyl alcohol (PVA) slurry.
