Description
Technical field
The present invention relates to a kind of dyeing, and in particular to a kind of dyeing and finishing technology of polyester-cotton fabric.
Background technology
Textile dyeing and finishing is a traditional industries of China, is also an important step of textile industry, Dyeing ＆ Finishing Industry
Level largely represents the level of a national textile industry, and its development is played a very important role, it is well known that
The compositions such as the greasy dirt that yarn fabric embryo cloth is produced during being made based on cottonseed, ash impurity, oil content etc. in fiber itself with spinning, rear
The compositions such as this oil content, impurity must be first removed before continuous dyeing process, here it is pretreatment procedure, through degraded, emulsification or dissolving etc.
After physico-chemical process processing, improve bright and clean fabrics cloth cover, dye-uptake, strengthen uniform level-dyeing property, reduction dyeing defect rate；In dye
Whole processing dyeing postprocessing working procedures are then cloth hair, loose colour, impurity for will being attached on dyed fabric etc., by being cleaned multiple times, soaping
Clean and tidy cloth cover is obtained etc. technique, it is ensured that product items fastness and its physics, appearance index reach requirement.
The general first oxygen bleaching pre-treatment of traditional processing mode, then disperse/active two one-bath two-step process dyeing, i.e., in weak acid
Contaminate and wash under the conditions of property；Add alkali reduction cleaning with sodium hydrosulfite again, remove PET fiber surface and stain scattered on cotton component
Dyestuff；Then neutralized with acetic acid, then with Dyeing of Cotton Fabric with Reactive Dyes component；Finally washed and entered with soaping agent after high temperature is soaped and located
Reason, reduction cleaning is carried out using sodium hydrosulfite, and sodium hydrosulfite harm is big, pollute heavy, cumbersome, technique and time length, energy consumption are big, no
Meet the requirement of environmental protection and energy-saving and emission-reduction, be further improved.
The content of the invention
The purpose of the present invention be overcome the shortcoming of prior art there is provided one kind reduce disposal of pollutants, optimize the environment, energy-conservation subtracts
The dyeing and finishing technology of the polyester-cotton fabric of row.
The present invention is adopted the following technical scheme that：
A kind of dyeing and finishing technology of polyester-cotton fabric, processing step is：Pre-treatment → dye washs → first time reduction cleaning → discharge opeing
→ hot wash → wash water → second of reduction cleaning → hot wash → fixation → softness → finished product, first time reduction cleaning and/or second
Secondary reduction cleaning includes：Add water, add 0.5-2g/L ACT, be warming up to 80-95 DEG C, be incubated 25-45min, discharge water.
Further, not discharge opeing after the dye is washed, is directly added into ACT and carries out first time reduction cleaning.
Further, the fixation includes：Add water, add formaldehyde-free color fixing agent, carry out fixation 15-25min.
Further, the formaldehyde-free color fixing agent is color fixing agent DM-2559C.
Further, the consumption of the color fixing agent DM-2559C is 0.5-1.0g/L.
Further, the softness includes：Add water, add 1.5-2.5g/L hydrophilic finishing agents, 1.5-2.5g/L hydrophilic soft
Soft dose, soft finish 15-25min.
From the above-mentioned description of this invention, compared with prior art, the beneficial effects of the invention are as follows：Utilize technique
Complementarity, dye is washed and united two into one with two single processes of reduction cleaning, has eliminated traditional sodium hydrosulfite alkaline reduction cleaning
Method, reduces pollution and harm that sodium hydrosulfite is brought, while reducing multiple hot wash and wash water, compared with traditional handicraft, reaches
The effect of environmental protection, energy-saving and emission-reduction is arrived；Fixation is carried out using formaldehyde-free color fixing agent, the harm that formaldehyde is brought, and ring is reduced
Ensure safety；Carried out using hydrophilic finishing agent and hydrophilic softening agent soft, thus it is possible to vary fabric structure and affinity, reach that lifting is wet
The effect of crock fastness.

Engineer testing：
First, new dyeing and finishing technology is contrasted with traditional dyeing and finishing technology
(1), new dyeing and finishing technology and traditional dyeing and finishing technology Contrast on effect
The new dyeing and finishing technology of table 1 and traditional dyeing and finishing technology Contrast on effect
Pass through table 1：The color fastness to washing of the product obtained using new dyeing and finishing technology, the white fastness of spelling reduce clear with tradition
The effect washed is basically identical, while improving security, the feature of environmental protection；New reduction cleaning replaces traditional sodium hydrosulfite also using ACT
Former cleaning, reduces pollution and harm that sodium hydrosulfite is brought, environmental protection；Not discharge opeing is directly carried out for the first time also after dye is washed
Original is cleaned and reduces the number of times of hot wash, has reached the effect of energy-conservation, meanwhile, COD have dropped 4000mg/L, alleviate at sewage
Reason is born, reduces disposal of pollutants, achieves noticeable achievement, so, new dyeing and finishing technology has reached that energy-conservation subtracts relative to traditional dyeing and finishing technology
Row, the effect of environmental protection.
(2), new dyeing and finishing technology is contrasted with traditional dyeing and finishing technology indices
The new dyeing and finishing technology of table 3 is contrasted with traditional dyeing and finishing technology indices
Pass through table 2：The traditional reduction cleaning technique of contrast and new reduction cleaning process energy consumption, new reduction cleaning technique phase
For traditional reduction cleaning technique, there are obvious optimization, the cylinder of water-saving 4, power saving in terms of time-consuming, power consumption, consumption vapour and auxiliary agent
16.1%th, vapour 16.3%, auxiliary agent are saved and saves 45 yuan/ton, integrated cost 388.63 yuan/ton of cloth of saving, energy-conserving and environment-protective, economic performance
Significantly.
In summary, new reduction cleaning technique replaces the sodium hydrosulfite of traditional reduction cleaning technique using ACT, reduces guarantor
Pollution and harm that dangerous powder is brought, improve the security of the feature of environmental protection and operation, and in time-consuming, power consumption, consumption vapour and auxiliary agent side
There is obvious optimization in face, meanwhile, COD have dropped 4000mg/L, alleviates sewage disposal burden, reduces disposal of pollutants, into
Effect is notable, so, new reduction cleaning technique has reached the effect of energy-saving and emission-reduction, environmental protection relative to traditional reduction cleaning technique
Really.
The above, only presently preferred embodiments of the present invention, therefore the scope that the present invention is implemented can not be limited with this, i.e.,
The equivalence changes made according to scope of the present invention patent and description and modification, all should still belong to what patent of the present invention covered
In the range of.
