Abstract
The invention discloses a cheese mercerizing method. The cheese mercerizing method includes: loose spooling, caustic soda processing, dewatering and spooling, caustic soda processing again, and then performing pre-processing, dyeing or whitening and the like according quality requirements after the second caustic soda processing is finished. A cheese staining jar is utilized as equipment to mercerize cheese, ordinary general equipment is utilized to realize yarn mercerizing process which requires multiple special equipment currently, processing effect is similar, and dyeing quality is not affected. In addition, compared with skein mercerizing, the cheese mercerizing method has the advantages of high production efficiency, low energy consumption, simple technology control, no requirement for the special equipment, flexible in batch production, and low labor intensity.
Description
Technical field
The present invention relates to textile printing and dyeing field, particularly relate to a kind of cheese mercerization finish method.
Background technology
Mariages light fabric in current industry, its by be made into after reeled yarn mercerising fabric again mercerising complete twice mercerising flow processing, gained fabric has strong mercerization effect, and feel, gloss are very good, but because price is higher, generally sell as high-grade fabric.
Reeled yarn mercerising general flow is: raw yarn, singe, unwinding skeining, reeled yarn mercerising, pre-treatment, dyeing, reeled yarn winder.Wherein unwinding skeining, the reeled yarn winder speed of a motor vehicle are slow, and reeled yarn fallibility batters knot, and need more manpower to carry out combing, production efficiency is low.Reeled yarn mercerising general single treatment 10-20kg reeled yarn, each process about 5min consuming time, manufacturing batch is little, and speed of production is low, simultaneously owing to needing the soda bath of lower temperature (general 20-24 DEG C) in technique, usually consumes mass energy and carries out cooling process.In addition, yarn singeing and reeled yarn mercerising need special equipment, especially reeled yarn mercerizing equipment, and the Tension Evenness of its tension arm requires high, and the external import of general needs is expensive.Because the production efficiency of reeled yarn mercerising is low, energy resource consumption large, apparatus expensive, causes mercerising yarn expensive, limit its range of application.
Yarn at present after a lot of general outsourcing mercerising of enterprise applying mercerising yarn carries out dyeing etc. following process, completes mercerized yarn finished product.Mercerising yarn main production process before dyeing is: raw yarn, singe, unwinding skeining, reeled yarn mercerising, oven dry, reeled yarn winder, shipment transport.Yarn after mercerising needs oven dry to carry out packaging shipment, and does not need to dry direct dyeing in autonomous production after mercerising, and the oven dry had more and transport operation more make this kind of product to the consumption of the energy and added cost.
Summary of the invention
Based on this, be necessary to provide a kind of cheese mercerization finish method that production efficiency is high, energy resource consumption is little, production cost is low.
A kind of cheese mercerization finish method, comprises the following steps:
(1), loose type coning: raw yarn is carried out loose type coning and obtains cheese, the bobbin density of described cheese is 0.22-0.50g/cm
3;
(2), caustic soda process: the cheese of step (1) is put into staining jar, adds the soda bath of 180-320g/L, 45-90 DEG C of process 1-15 minute, drain soda bath the cleaning that adds water, the pH value neutralizing described cheese is 5-9.5;
(3), dehydration also winder: take out burning alkali-treated cheese in step (2), dehydration is less than 55% to the moisture content of described cheese, obtain the cheese after dewatering, then the cheese after described dehydration is carried out winder, obtaining bobbin density is 0.22-0.50g/cm
3cheese;
(4), caustic soda process again: the cheese in step (3) is put into staining jar, add the soda bath of 180-320g/L, 45-90 DEG C of process 1-15 minute, drain soda bath the cleaning that adds water, the pH value neutralizing described cheese is 5-9.5.
Wherein in an embodiment, described in step (1), the bobbin density of cheese is 0.3g/cm
3.
Wherein in an embodiment, described step (2) is for put into staining jar by cheese, add the soda bath of 280g/L, be warming up to 70 DEG C of insulations 5 minutes, to drain soda bath, add water and be warming up to 80 DEG C of washings 5 minutes, again add water after discharge opeing and be warming up to 80 DEG C of washings 5 minutes, discharge opeing, the pH value neutralizing described cheese is 7-8.
Wherein in an embodiment, described in step (3), the bobbin density of cheese is 0.4g/cm
3.
Wherein in an embodiment, described step (4) is: the cheese in step (3) is put into staining jar, add the soda bath of 280g/L, be warming up to 70 DEG C of insulations 5 minutes, to drain soda bath, add water and be warming up to 80 DEG C of washings 5 minutes, again add water after discharge opeing and be warming up to 80 DEG C of washings 5 minutes, discharge opeing, the pH value neutralizing described cheese is 7-8.
Above-mentioned cheese mercerization finish method carries out mercerization finish for equipment to cheese to adopt cheese dyeing cylinder, achieve the yarn mercerization needing multiple task equipment to complete at present, and treatment effect is close, does not affect dyeing quality with general common apparatus.In addition, can carry out pre-treatment by product requirement after completing caustic soda process again, dye or the operation such as brighten, described mercerization finish method is compared with existing reeled yarn mercerising form processing, and tool has the following advantages:
1, production efficiency is high, and compared with the unwinding skeining of reeled yarn mercerising and reeled yarn winder, the winder speed of a motor vehicle in the middle of loose type coning and twice caustic soda process is fast, and its production efficiency is higher than reeled yarn mercerising.
2, energy resource consumption is little, and the soda bath of reeled yarn mercerising needs the rear use of cooling, consumes mass energy.And caustic soda processing requirements temperature described in above-mentioned mercerization finish method is within the scope of 45-90 DEG C, and caustic soda can release a large amount of heat being dissolved in water in dilution, therefore in caustic soda treatment step of the present invention, do not need heating, solution temperature just can reach about 45 DEG C, reduces the consumption of the energy in production procedure.
3, technology controlling and process is simple, and general reeled yarn mercerising needs to apply tension force to reeled yarn, and the Tension Evenness of tension arm etc. need strict control.The present invention utilizes the swelling effect making a yarn tight of yarn in caustic dip process, and provide some tension to yarn, technology controlling and process is easy.Make the ectonexine treatment effect of bobbin even by the technological process of caustic soda process, dewater also winder, caustic soda process again, after dyeing, bobbin ectonexine color distortion is little simultaneously.
4, do not need task equipment, the present invention does not need proprietary yarn singeing, mercerizing equipment, and available general cheese dyeing cylinder processes.For the former enterprise needing outsourcing mercerising yarn, autonomous production can be carried out.Outsourcing mercerising yarn of comparing carries out dyeing etc. the production procedure of operation, utilizes cheese yarn dyeing equipment autonomously to produce the production cost such as the oven dry after eliminating mercerising and transport, also shortens the production cycle.
5, production lot is flexible, and reeled yarn mercerising production efficiency is lower, and produce in enormous quantities to add and produce pressure man-hour greatly, and the present invention is owing to can process with different capabilities staining jar, its production lot is more flexible.
6, personnel labor intensity is low, and because yarn entanglement, knotting problem easily appear in reeled yarn in operation, work in-process needs operations such as manually making in order, and the workload of operating personnel is large.The present invention adopts loose type coning and winding procedure to process cylinder yarn, and yarn is without the problems referred to above, easy to operate and workload is little.
