Abstract
The invention discloses a kind of method for removing cotton seed hullss on bafta using ozone in the liquid phase, belongs to textile technology field.The present invention carries out cotton seed hullss removal using the high oxidative of ozone to bafta, and clearance reaches 80%, with alkaline process 60%, the 65% of hydrogen peroxide and enzyme process 45% compared with, effect is more significantly.The inventive method removes cotton seed hullss using ozone gas, it is not necessary to heat, can be with energy saving, while harmful gass.Ozone goes cotton seed hullss operation simply, and use cost is low.The present invention carries out free radical scavenging agent solution washing process also by the bafta processed through ozone, removes the hydroxyl radical free radical of residual, active oxygen atom etc. on fabric, it is ensured that fabric performance indications such as whiteness value, degree of polymerization in follow-up placement process are stable.
Description
Technical field
The present invention relates to a kind of method for removing cotton seed hullss on bafta using ozone in the liquid phase, belongs to textile technology neck
Domain.
Background technology
Cotton seed hullss itself are not the Symbionts on fiber, and when unginned cotton is after cotton ginning, Semen Gossypii and cotton fiber are separated,
But the relic for still having the cotton seed hullss of a small amount of grating is attached on fiber.After spinning, they are just embedded in yarn fiber, quality
Hard and color is deeper, had 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 hullss is lignin, tannin, cellulose, hemicellulose and other polysaccharide, also few
Amount protein, oils and fatss and mineral, 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, Syringa oblata Lindl. 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 the chemical composition with regard to lignin, so far not yet can be accurate
Determine, just know that at present.Cotton seed hullss are to be relatively difficult to one of impurity of removing.
At present in commercial production, except the main method being related to of cotton seed hullss 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 hullss
Phenolic hydroxyl group is acted on Caustic soda, the decomposition on recurring structure, and relative molecular mass reduces so as to the dissolubility increase in alkali liquor,
So as to be removed.Meanwhile, middle addition sodium sulfite in alkali liquor can make lignin formation be soluble in the derivant of alkali and be gone
Remove.In addition, in high temperature Caustic soda long duration of action, cotton seed hullss occur 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 Semen Gossypii shell structure, alkaline process can not be completely removed
The cotton seed hullss of fabric face, and a large amount of Caustic soda, table will be used to live, need high temperature to process for a long time, after process, want big calorimetric
Water, cold water washing, therefore this method except cotton seed hullss there is a problem of power consumption, water consumption, pollute greatly, efficiency low, and carry at present
The energy-saving and emission-reduction advocated, economic and environment-friendly theory fail to agree.Alkaline process prescription：Sodium hydroxide 10g/L, sodium sulfite 1g/L, sodium silicate
1g/L, dodecylbenzene sodium sulfonate 1g/L；Process conditions：Bath raio 1:40,90 DEG C of reaction temperature, time 2h.
(2) enzyme process is a kind of mode for comparing environmental protection, 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 hullss clearance is less better.Further, since complicated component in cotton seed hullss, the specificity of enzyme is higher, every kind of enzyme
Can only be directed to process a kind of or and its derivant, cotton seed hullss are 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 warp
Cross high temperature, highly basic swelling, removal that cotton seed hullss effectively can be degraded.In addition, it can also be with uveal conjugated double bond in cotton seed hullss
Reaction so as to which the original conjugated system fracture of inside and outside uvea, color development system are destroyed, and make cotton seed hullss 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 is produced
System can only remove a part of impurity, and roguing effect is not ideal.The hydrogen peroxide prescription having been reported：30%H2O25.0g/L, steady
Determine agent 1.0g/L, sodium hydroxide 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
Should after want massive laundering, consume energy water consumption, and flow process is longer, and can not completely remove cotton seed hullss after processing, and clearance only has
60% or so, less efficient.Enzymatic treatment, due to the specificity of enzyme too strong, it is impossible to for each impurity in cotton seed hullss, and enzyme
The effect for being not so good as alkali to the effect of cotton seed hullss is good, and clearance only has 40% or so, and roguing effect is poor.Hydrogen peroxide oxidation compared with
Good, while there is roguing effect, but a large amount of Caustic soda, chemical reagent to be used, need high-temperature process, after process, need massive laundering
Wash, pollution is larger, and the clearance of cotton seed hullss only has 65%, and effect is not ideal.
Therefore, it is necessary to develop new method to overcome these problems.
Content of the invention
Existing problems are removed in order to solve cotton seed hullss in existing bafta, the invention provides one kind is in liquid phase
The method that middle utilization ozone removes cotton seed hullss in bafta.The inventive method makes cotton seed hullss constituent using the strong oxidizing property of ozone
Matter progressively ruptures, decomposes, and gradually eliminates its pigment, finally removes cotton seed hullss.Ozone is strong with cotton seed hullss effect, it is not necessary to
High-temperature heating treatment, it is not required that using a large amount of chemical reagent, need to only carry out simple washing and need not consume a large amount of water after bleaching,
Without a wastewater treatment difficult problem, it is a kind of efficient, pretreatment mode of energy-conservation.
The present invention removes fabric face cotton seed hullss using effect of the ozone to cotton seed hullss, first will process through desizing
Bafta dipping containing certain nonionic penetrant solution, subsequently into ozone reaction room in, make one section of fabric and ozone contact
Time response, then removes remaining ozone activity group on fabric through rinsing, then washes through hot water wash, cold water, finally
Dried.
