Abstract
The invention relates to a bleaching process and particularly relates to a novel bleaching process of a cotton-flax polyester-cotton woven fabric. The novel bleaching process comprises the following steps of singeing, boiling off, bleaching by oxygen, mercerizing, re-bleaching, sizing, whitening and softening and pre-shrinking. The novel bleaching process is characterized in that the re-bleachingstep adopts a novel short-evaporating and re-bleaching process; and the novel bleaching process comprises the specific steps of: after rolling special compound working liquid for padding and carryingout the short evaporating, feeding the rolled special compound working liquid into an evaporation box to be steamed for 1.5 minutes at 98-102 DEG C; washing the special compound working liquid by utilizing hot water of 90 DEG C; and after rolling cloth, feeding the cloth into a drying barrel so as to be dried. According to the novel bleaching process, the re-bleaching and the steaming only need 1.5 min, so that a large quantity of steam is saved, energy is saved and consumption is reduced; and the novel bleaching process improves the water washing resistance, each color fastness and whitenessof a whitened textile produced by continuous dyeing.
Description
Technical field
The present invention relates to a kind of bleaching process, relate in particular to a kind of linen-cotton polyester-cotton blend shuttle-woven fabric bleaching process, belong to technical field of textile printing.
Background technology
The bleaching of the woven that the long vehicle continous mode is produced in recent years requires more and more higher.At present, though long vehicle production BLEACHED FABRIC can be accomplished fabulous poor end to end, its washability is poor at present, does not reach the Washing of the BLEACHED FABRIC that overflow dyeing machine produces, and float again if add brightening agent, can cause brightening agent to stain to the fabric of the oxygen bleaching process of the general flow of back.In addition, steaming time needs about 40 minutes when traditional handicraft is floated again, has to consume a large amount of steam.
Summary of the invention
The present invention has aimed to provide a kind of linen-cotton polyester-cotton blend shuttle-woven fabric bleaching process, has remedied the weak point of long vehicle fabric brightening processing back water-wash resistance and COLOR FASTNESS difference in the time of energy-saving and cost-reducing.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
A kind of linen-cotton polyester-cotton blend shuttle-woven fabric bleaching process, comprise singe, kiering, oxygen are floated, mercerising, soft, the preshrunk of Jia Baijia of floating again, finalize the design, it is characterized in that: the described step of floating again adopts the short multiple bleaching process that steams, specifically may further comprise the steps: will pad and enter steam box after the short composite working solution that steams special usefulness rolls 98-102 ℃ of decatize 1.5 minutes, the composite Working solution prescription of special usefulness is hydrogen peroxide 3g/L, whitener R SB 2g/L, low temperature soaping agent 5g/L, the clean white LF-123 3g/L of fiber crops; Clean with 90 degrees centigrade of hot water; Enter the drying cylinder oven dry after mangling.
Hydrogen peroxide in the composite working solution can be removed cotton seed hulls makes fabric reach certain whiteness, and make the fibre damage minimum, whitener R SB possess certain whiteness and affinity medium, be easy to control aberration end to end, the low temperature soaping agent, just possess fabulous dispersion removal impurity and the effect of decolouring about low temperature 75 degree, the clean "white expert"'s door of fiber crops is used for the nano grade inorganic mineral matter that linen is handled, and has emulsification and controls the effect of stablizing decomposing hydrogen dioxide solution through contrast test.
The described step of singing adopts gas singeing machine, and two positive two is anti-, and the speed of a motor vehicle is 90 minutes/meter.
Described kiering step employing continous track formula is boiled and is floated machine, and may further comprise the steps: pad prescription after light thermokalite cleans and be the working solution of caustic soda 20-70g/L, refining agent 5g/L, dispersant 3g/L, liquid carrying rate is 98%-110%; Go into steam box at 98-102 ℃ of decatize 80-90 minute after padding with high feeding; Clean with the hot water refluence after going out steam box; Padding machine mangles.
Described oxygen floats and may further comprise the steps: clean with cold water; Add prescription and be the bleaching working solution of caustic soda 1g/L, refining agent 3g/L, dispersant 2g/L, hydrogen peroxide 3g/L, waterglass 5g/L, liquid carrying rate is 98%-105%; Went into the steam box decatize 45 minutes after padding with high feeding; Clean with the hot water refluence after going out steam box; After mangling, padding machine enters the drying cylinder oven dry.
The caustic soda concentration that described mercerising step adopts is 180-240g/L.
It is 150-160 ℃ that described typing adds the soft setting temperature that adds white step, and the speed of a motor vehicle is 70 meters/minute.
The present invention has following beneficial effect owing to adopt above technical scheme:
1, floating decatize again only needs 1.5 minutes, saves a large amount of steam, energy-saving and cost-reducing;
2, float again, brighten with bathing and carry out, improved water-wash resistance, every COLOR FASTNESS and the whiteness of the brightened goods of long vehicle production.
