Abstract
The invention provides a grey cloth cold batch mercerizing process method for cotton and cotton blended fabric, which belongs to a dyeing and finishing pretreatment process for cotton and cotton blended fabric. The process method comprises processes of singeing, alkali padding, rolling, reverse rolling and heaping, washing, oxygen bleaching, weft finishing and tentering; in the alkali padding process, alkali liquor is padded by using a padding liquor roller, the NaOH content of the alkali liquor in an alkali liquor tank is 160 to 180 grams per liter, the balance is water, and the alkali liquor in the alkali liquor tank is circulated by using a circulating pump; in the washing process, counter current washing is performed in a de-sizing machine by using 90 to 95 DEG C hot water, the speed is 48 to 52 meters per minute, and the cloth falls with tide; and in the oxygen bleaching process, the speed is 45 minutes per minute, the temperature in a track-type steam box is between 96 and 99 DEG C, and the heaping is performed for 45 minutes. The mercerizing process method combines the mercerizing process and the de-sizing process into a one-step process so as to shorten the process flow, reduce the steam consumption, relatively reduce the consumed caustic soda quantity and save the wastewater treatment expense.
Description
Technical field
The present invention relates to a kind of cotton and cotton blended fabric grey cloth carried out the process that mercerising is handled, belong to the dyeing and finishing processing pre-treatment process of a kind of cotton and cotton blended fabric lining.
Background technology
Cotton products (yarn, fabric) are having under the condition of tension force, pad drip washing with concentrated caustic solution and handle, and the processing procedure of flush away caustic soda under tension force is called " mercerising processing " technology then.After cotton fiber soaks into concentrated caustic solution, can observe the irreversible violent swelling of cotton fiber, fiber cross sections changes circle into by flat kidney shape, and cell also shrinks, and natural longitudinally distortion disappears, contraction in length.If when fiber is applied tension force, soak concentrated base, do not make filament contraction, this moment, the fiber surface wrinkle disappeared, and became very smooth cylinder, and light is reflected regularly and demonstrates gloss.If alkali lye on the fiber is removed in washing when tension force continues to exist, the form in the time of just can be basically the cotton fiber swelling remains, and becomes irreversible swelling, and this moment, the gloss of acquisition was more durable.Because caustic soda can get into cotton fiber inside, the variation on supramolecular structure and the morphosis has taken place in cotton fiber, makes the part crystalline region change the amorphous region into, and lixiviating, this situation in washing back also remain basically.Except improving gloss, and increased chemical activity, therefore the absorption property of cotton fiber also greatly increases, and the dyestuff absorbability is increased, and fabric size is also more stable, and brute force, extensibility etc. all increase to some extent.Cotton and BLENDED FABRIC change below can taking place behind the mercerising: 1, glossiness improves; 2, adsorption capacity, the chemical reaction ability to dying auxiliary agent strengthens; 3, washing DIMENSIONAL STABILITY, fabric flatness are improved; 4, brute force, extensibility etc. are taken mechanical performance and are also made moderate progress.The mercerising treatment effect of cotton blended fabric is also like this.
In present cotton and the cotton blended fabric mercerization, use chain mercerizer or straight roller mercerizing range to carry out mercerising, need a large amount of steam, also will carry out destarch separately after mercerising is handled and handle, technological process is long, and the steam consumption is big, and energy consumption is high.And owing to use the caustic soda of a large amount of high concentrations,, but still to a certain extent the processing of dyeing waste water is caused burden even if adopted alkali recovery technology.
Summary of the invention
Technical problem to be solved by this invention is, the grey cloth cold batch mercerizing process method of a kind of cotton and cotton blended fabric lining is provided,, the purpose of practicing thrift energy-conservation to realize.
The present invention is achieved in that the grey cloth cold batch mercerizing process method of a kind of cotton and cotton blended fabric lining, described process singes, rolls alkali, clot successively, rewind bank up, washing, oxygen are floated, whole latitude tentering operation; In the operation of singing, adopt two burner gassing frames that spray, the flame jet velocity is the 7-28 meter per second, the speed of a motor vehicle be 105-110 rice/minute, positive, reverse side all burns once, blast is 18-22Mpa, 1100-1300 ℃ of burner temperature; In rolling the alkali operation, with mangle coiler alkali immerging, the NaOH content in the alkali lye in the lye tank (vat) is 160-180g/L, and all the other be water, uses circulating pump that the alkali lye in the lye tank (vat) is circulated, roll the alkali speed of a motor vehicle and be 48-52 rice/minute, padding machine pressure is 2kg/cm
2Roll clot behind the alkali, rewind after the clot and bank up 8 hours; In washing step, in desizing machine, with 90-95 ℃ hot water adverse current washing, speed of a motor vehicle 48-52 rice/minute, ebb cloth; In oxygen bleaching process, 45 meters/minute of the speed of a motor vehicle, in the crawler type steam box temperature 96-99 ℃; Banked up 45 minutes, the NaOH content in the oxygen bleaching liquor is 5-6g/L, and hydrogen peroxide content is 3-4g/L; Waterglass content is 3-4g/L, and scouring agent BYZ-6 content is 4-4.5g/L, and penetrating agent JFC content is 1-2g/L; Low alkali pretreating reagent DKB-321 content is 4-6g/L, and all the other are water.
This mercerization method; Saved this operation of destarch; Two step of mercerising and destarch operation is combined into a step operation, and its maximum characteristics are without chain mercerizer or straight roller mercerizing range mercerising, but after using mangle coiler alkali immerging at normal temperatures; Bank up, wash processing, realized the rayon gray fabric cold batching mercerising.Like this, both shortened technological process, and avoided the steam of chain mercerizer or straight roller mercerizing range to expend again, thereby practiced thrift destarch stage and mercerising stage two a large amount of steam economies of operation; Consuming caustic soda amount also reduces relatively.Traditional mercerization caustic soda concentration generally is controlled at 240～280g/L; Fabric sheen and improvement dyeability all there is effect preferably; And being low to moderate 160g/L, the present invention's the employed caustic soda concentration of grey cloth mercerization method can reach this requirement; Reduce the alkali consumption, thereby practiced thrift the wastewater treatment expense; And adopted legacy equipment, dyestuff dye-uptake when having proposed high dyeing.Production shows that the mercerising quality of the product of this explained hereafter is compared with traditional mercerization, does not have significant difference.
