Description
Technical field
The present invention relates to a kind of cotton or the pre-treating method of polyester cotton, belong to textile technology field.
Background technology
In order that cotton and polyester cotton smoothly weaving, it is necessary to carry out starching to the warp thread of cotton and polyester cotton,
To improve the wearability of warp thread and strength, patch volt filoplume, sizing agent used is referred to as slurry.Current slurry is mainly starch
And PVA, starching amount are generally the 8%-12% through yarn quality, wherein starch accounts for 70%-100%, and PVA accounts for 0%-30%, specifically
Depending on kind.After the completion of weaving, on slurry need to remove, otherwise can influence the outward appearance of fabric, feel and follow-up
The progress of the processes such as dyeing, stamp, final finishing.This process is commonly referred to as desizing.
The pre-treatment of cotton and polyester cotton includes desizing and concise, refers to remove cotton using the method for chemistry or biology
On the starch on polyester cotton warp thread and PVA slurries (this process of removal desizing is commonly referred to as desizing) and cotton fiber
The cotton seed hulls remained in natural impurity, mainly pectin, cotton wax and cotton fiber processing.Remove cotton fiber on natural impurity this
Process is referred to as concise.
For a long time, the desizing of cotton and polyester cotton mainly uses chemical method, utilizes the soda bath (5- of heat
It can 10g/L) make starch and acutely swelling occurs for PVA, the principle of solubility raising carries out high-temperature process, then be gone with hot wash
Remove.Although also the fabric of some kinds can use amylase carry out desizing, primarily directed to pure starch starching, be free of
The fabric of PVA slurries, the yarn count of these fabrics is thicker, and class is relatively low.And for ramuscule high density fabric and polyester cotton,
On slurry besides the starch, also 20%-30% PVA slurries, amylase is not acted on PVA slurries, and decomposed P VA
Enzyme there is no commercialization still at present.So the desizing to these fabrics is at present or using flux-calcined chemical method.
The concise chemical method at present and using caustic soda processing for removing natural impurity on cotton fiber, utilizes heat
Sodium hydroxide can make fatty acid ester saponification in the waxy substance on cotton fiber, aliphatic acid generation sodium salt, can make pectin substance and
Nitrogen substance is hydrolyzed into the material of solubility and removed, and swelling can occur in alkali cooking process for cotton seed hulls becomes soft, then through water
Wash, cotton seed hulls disintegrates and splits away off this principle, then is aided with appropriate surfactant, makes unhydrolyzable nytron
Thing emulsifies, and further improves scouring result.
Last century Novozymes Company of the nineties Denmark and Osaka, Japan university develop alkaline pectase and former fruit respectively
After glue enzyme, research is proceeded by using biological enzyme technology is concise to bafta progress.Relevant cotton fabric with enzymes essence both at home and abroad
Experienced research, initially pay attention to remove the pectic substance on cotton fiber using pectase, to improve the wetability of cotton fiber.Into two
In tenth century, start to turn to the synergy for studying the complex enzyme that is formed after the mixing of different enzymes to improving cotton fiber wetability, its
Emphasis is pectase and cellulase, or adds protease, lipase, lignoenzyme, and spell after using has one to cotton pretreatment
Fixed synergy, the impurity on cotton fiber can be effectively removed, but a certain distance compared with alkali process also be present.Therefore,
It is concise to bafta progress using the biology enzyme of commercialization, although having carried out substantial amounts of research, also prematurity so far, only in reality
Test room and make some explorations, there is no industrial precedent.Main cause is the diversity of natural impurity on cotton fiber, except containing
Outside 1% or so pectin, also containing 0.6% or so cotton wax (some composition hydrocarbons in cotton wax, it is impossible to by enzyme point
Solution, influence the wetability of cotton fiber), 1.3% or so nitrogen substance, the cotton seed hulls particularly on cotton fiber, complicated component, knot
Structure is stable, it is impossible to is decomposed by general enzyme.Therefore, even if being handled after being compounded using a variety of commercial enzymes bafta, it moistens
Moist (typically being represented with capillary effect) is very undesirable, can not meet follow-up dyeing, the requirement of stamp and final finishing to wetability.Especially
It is that surface of cotton fabric also has cotton seed hulls residual after handling, has had a strong impact on the outward appearance and dyeing quality of fabric.
In a word, there are the following problems for the pre-treatment of current cotton and polyester cotton：
(1) it is usually to carry out desizing and concise point of two steps, be i.e. desizing → washing → concise → washing, is so increased by
Technological process, adds the consumption of water, electric vapour and chemicals, reduces the service efficiency of equipment, reduce production efficiency, together
When also add COD value in sewage load and waste water.
(2) flux-calcined chemistry is still used for the cotton containing PVA slurries and polyester cotton, current desizing
Method.This method simply dissolves starch and PVA slurries, does not decompose, therefore, the COD value severe overweight of desized wastewater, shadow
Ecological environment is rung；Moreover, the pH value of waste water of discharge is high, stronger alkali and high-temperature process can also damage fiber；In addition, alkali desizing
After need repeatedly to wash, consume substantial amounts of water.
(3) the alkali refining process used at present goes the natural impurity dissolving on cotton fiber also with the aqueous slkali of heat
Remove, there is also alkali desizing it is same the problem of, i.e., the COD value of concise waste water is high, pH value is high, and water consumption is big, serious to fibre damage.
And the method for using enzymatic scouring, due to the selectivity of the diversity of natural impurity and enzyme effect on cotton fiber, having on cotton fiber
A little impurity are difficult to remove, and the wetability of concise rear cotton or polyester cotton is difficult to meet the needs subsequently dyed, and cotton is knitted
Cotton seed hulls is also remained on thing.
(4) bafta is handled after enzyme compounding, its wetability (typically being represented with capillary effect) is very undesirable, can not meet
Follow-up dyeing, the requirement of stamp and final finishing to wetability.Surface of cotton fabric also has cotton seed hulls residual after particularly handling, seriously
It has impact on the outward appearance and dyeing quality of fabric.
