Description
Technical field
The invention belongs to textile dyeing and finishing technical field, and in particular to before desizing, boiling-off, bleaching, the mercerising of woven cotton
Processing method.
Background technology
The desizing of the species woven fabric such as above-mentioned cotton, full-cotton elasticity, polyester cotton blending, boiling-off, bleaching, mercerising pre-treatment,
In whole dyeing and finishing process, process number accounting is 25.00-33.33%, water, electricity, and the energy consumption accounting such as vapour is up to 60-65%, especially work
Sequence water consumption accounting is more up to 75-80%；A large amount of production waste water are also that dyeing affects the primary pollution source of social environment.
At present by different process combinations, only can will move back, boil, floating three-procedure and be simplified to two steps or a step half, and mercerising is all the time
It is single processing step.Mercerizing process is in addition to configuration production board, in addition it is also necessary to configures weak lye in large scale and reclaims,
Storage and inspissation facility.
The content of the invention
It is an object of the invention to provide it is a kind of can reducing energy consumption, economize on resources, favorable environment protection mercerizer
The cotton pre-treating method that sequence is merged with desizing, boiling-off, bleaching process.
The cotton pre-treating method that mercerizing process and desizing, boiling-off, bleaching process are merged that the present invention is provided,
It is a kind of cotton cold pad--batch mercerising boiling and bleaching process using the pre-treatment that cotton is completed with one step mode of bath.
The cotton pre-treating method that the present invention is provided, concretely comprises the following steps：
Fabric pads NaOH-H2O2Cold pad--batch mercerising boils bleaching liquor；
Spool is banked up；
Continuous open washing drying；
Mercerising is boiled and bleached cloth.
Wherein, every liter of NaOH-H2O2Cold pad--batch mercerising boils the formula of bleaching liquor and consists of：
Every liter of NaOH-H2O2Cold pad--batch mercerising boils the formula of bleaching liquor and consists of：
30% NaOH： 400—550ml
30% H2O2: 50—60ml
Multi-functional compound auxiliary： 35-45ml
H2O:Surplus/L.
Above-mentioned multi-functional compound auxiliary, comprising:Stabilizer ONE：30—35ml；Dispersant MW：2—5ml；Surfactant
OP：3-5ml, is commercial products.
It is described to pad NaOH-H2O2Cold pad--batch mercerising boils bleaching liquor, and in 70-100L liquid measures, open width fabric continuously impregnates
10-15 seconds, by roll pressure point, keep pick-up rate 60-70%（To cloth weight）.
The spool is banked up, synchronous before and after the open width fabric after padding, constant tension winding on A shaped frame cloth beams, shape
Into 2000-3000 meters of cloth beams, outer layer is coated with plastic sheeting；By itself transmission device, 6-8r/min rotary states are kept,
Under 15-35 DEG C of room temperature conditions, bank up 24-72 hours.
The continuous open washing drying, on 8-10 open washing units and drying unit associations board, 90 DEG C of companies are done in cloth beam debatching
Continuous open washing drying, or reciprocating 90 DEG C of open widths washing, the drying of squezzing afterwards are done on dye jigger.
The characteristics of the inventive method is：
（1）Technique is highly integrated, can be with normal with the desizing of cotton, boiling-off, bleaching, the step of mercerising four is completed with one step mode of bath
Rule pre-treatment, without the need for repeatedly padding, banking up or 100 DEG C of decatizes and open washing drying course.
（2）By the synergy of formulation adjuvant, stability of the hydrogen peroxide in high concentration mercerising alkali lye can have both been solved
A difficult problem, while and reaction interface tension force can be reduced, keep synchronous, the balance quality of various pre-treating technologies；Make full use of height
The chemical energy of concentration mercerising alkali, without the need for additional engineering heat energy, finally achieves the conservation of energy of various reactions.
Advantage using cotton cold pad--batch mercerising boiling and bleaching process of the present invention is：
A. energy-conservation：Water saving 32.66-66.38%, economize on electricity 64.77-71.54% saves vapour 36.09-64.41%, and energy-conservation is total
Meter：39.45—65.15%；
B. environmental protection：Because NaOH plays desizing, boiling-off, bleaching, mercerization simultaneously, the NaOH of every kilogram of cloth pre-treatment is made
Consumption declines 33.33-44.83%, reduces sewage quantity 32.66-66.38%；
C. work efficiency is improved：Reduce cost of labor 30.11-54.78%；
D. the percentage of A-class goods is improved, can reduces by 80% defective cloth rate；
E. economic benefit：Saving pre-treating technology totle drilling cost is：19.03—40.70%.
In sum, the application of cotton cold pad--batch mercerising boiling and bleaching process, energy improve product quality is more beneficial for environment guarantor
Shield；In reducing energy consumption, saving water resource, raise labour productivity and all many-sides such as economic benefit, suffer from extremely obvious
Advantage.
