Abstract
The invention discloses a method of using ozone for removing cottonseed hulls in baffeta in the gas phase, and belongs to the technical field of textile. High oxidability of ozone is used for removing the cottonseed hulls in baffeta, the removal rate reaches 85%, and compared with an alkaline method, a hydrogen peroxide and an enzymic method, the effect is more remarkable. The ozone gas is used for removing the cottonseed hulls without heating, energy can be saved, and harmful gas is avoided. The method of using ozone for removing the cottonseed hulls is easy to operate and low in use cost. The baffeta obtained after ozone treatment is washed and treated with a free-radical scavenger solution to remove residual hydroxyl radicals and active oxygen atoms on the baffeta, and it is ensured that performance indexes such as whiteness value and polymerization degree of the baffeta are stable in the follow-up placing process.
Description
Technical field
The present invention relates to a kind of method for removing cotton seed hulls in bafta using ozone in the gas phase, belongs to textile technology neck
Domain.
Background technology
Cotton seed hulls itself is not the commensal on fiber, and when unginned cotton is after cotton ginning, cottonseed and cotton fiber are separated,
But the relic for still having the cotton seed hulls of a small amount of grating is attached on fiber.After spinning, they are just embedded in yarn fiber, quality
It is hard and color is deeper, have a strong impact on the outward appearance of fabric, it is therefore desirable to removal is should give in the pretreatment process of bafta.
The chemical composition of cotton seed hulls is lignin, tannin, cellulose, hemicellulose and other polysaccharide, also few
Amount protein, grease and mineral matter, lignin account for 25～28% or so.Lignin be constitute plant skeleton main component it
One, its chemical constitution is extremely complex, it is considered that its basic structural unit is phenylpropyl alcohol alkane, has three basic structures：Wood to be created
Base propane, lilac base propane and p-hydroxyphenyl propane, are bonded by ehter bond and C-C between these construction units and are connected together,
Form the natural phenolic atactic polymer with three-dimensional structure.But with regard to the chemical composition of lignin, so far not yet can be accurate
Determine, in just knowing that its structure at present, there is more phenolic hydroxyl group.Cotton seed hulls is to be relatively difficult to one of impurity of removing.
At present in industrial production, except the main method being related to of cotton seed hulls has alkaline process, enzyme process and hydrogen peroxide method.
(1) alkaline process is the most wide method of current range of application, on the main component lignin in reaction in cotton seed hulls
Phenolic hydroxyl group is acted on caustic soda, the decomposition on recurring structure, and relative molecular mass is reduced so as to the solubility increase in alkali lye,
So as to be removed.Meanwhile, it is middle in alkali lye to add sodium hydrogensulfite, lignin formation can be made to be soluble in the derivative of alkali and be gone
Remove.In addition, in high temperature caustic soda long duration of action, cotton seed hulls occur it is swelling, become soft, partly through washing and rub with the hands sassafras make
With just splitting away off from fabric.But in actual production, due to the complexity of cottonseed shell structure, alkaline process can not be completely removed
The cotton seed hulls of fabric face, and will be lived using a large amount of caustic soda, table, need high temperature to process for a long time, after process, want big calorimetric
Water, cold water washing, therefore this method except cotton seed hulls there is a problem of power consumption, water consumption, pollute greatly, efficiency it is low, and carry at present
The energy-saving and emission-reduction advocated, economic and environment-friendly theory fail to agree.Alkaline process prescription：NaOH 10g/L, sodium hydrogensulfite 1g/L, sodium metasilicate
1g/L, neopelex 1g/L；Process conditions：Bath raio 1:40,90 DEG C of reaction temperature, time 2h.
(2) enzyme process is a kind of environmentally friendly mode of comparison, and compared with alkaline process, enzyme process is few with water, and treatment fluid contaminated wastewater is little, but
Its effect such as cotton seed hulls clearance is less better.Further, since complicated component in cotton seed hulls, the selectivity of enzyme is higher, every kind of enzyme
Can only for process it is a kind of or and its derivative, cotton seed hulls is due to lacking that its complicated structure and composition has been doomed that enzyme process uses
Fall into.Existing enzyme process prescription：Efficient composite enzyme 1.5g/L, sodium chloride 5.0g/L, tune pH value 6-7；Flow process：Bafta impregnates enzyme liquid
(55～60 DEG C) isothermal holding (60min) hot water wash (80 DEG C) cold water washes drying
(3) hydrogen peroxide is a kind of stronger oxidant, and it can decompose production peroxide radical ion in the basic conditions, in Jing
Cross high temperature, highly basic swelling, removal of effectively degrading to cotton seed hulls.In addition, it can also be with uveal conjugated double bond in cotton seed hulls
Reaction so as to which the original conjugated system fracture of inside and outside uvea, color development system are destroyed, and make cotton seed hulls colour killing reach removal
Effect.But the processing mode needs high temperature, long time treatment, using a large amount of chemical reagent, a large amount of waste water, and its oxysome are produced
System can only remove a part of impurity, and impurity elimination effect is not ideal.The hydrogen peroxide prescription having been reported：30%H2O2It is 5.0g/L, steady
Determine agent 1.0g/L, NaOH and adjust pH=11 or so；Flow process：(95～100 DEG C) guarantors of fabric impregnation process liquid of pretreatment
Temperature processes (100 DEG C, 60min) hot water wash (80 DEG C) cold water and washes drying.
Current alkaline process, using a large amount of caustic soda, auxiliary agent, the waste liquor contamination after process larger (COD value is high) is difficult to process, instead
