Description
Technical field
The invention belongs to textile dyeing and finishing technical field, and in particular to a kind of bafta low temperature is scouringed and bleaching single bath process technique.
Background technology
Cotton fiber is most important natural fiber raw material, and bafta is due to its good hygroscopicity, and wearability is good, easy dyeing,
Receive the favor of consumers in general so that it occupies leading position in field of textiles.But containing substantial amounts of in raw cotton fabric
Pectin, impurity and the natural pigment such as grease, whiteness and vividness fail to reach impurity and natural colour in quality requirement, bafta
Element needs to sequentially pass through concise and bleaching removal.
The concise mode generally used at present is concise for alkali, and method for bleaching is hydrogen peroxide bleaching, and the bafta after processing is white
Degree and retention of whiteness can preferably, but this method can be only achieved required whiteness in high temperature, strong basicity, and energy consumption is larger, right after bleaching
The damage of fiber is also larger, and two-step method process does not reach the requirement of national energy-saving emission reduction.
The content of the invention
Knitted in view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to now provide the cotton that a kind of technique is simple and convenient to operate
Thing low temperature is scouringed and bleaching single bath process technique.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of bafta low temperature is scouringed and bleaching single bath process work
Skill, its innovative point is：By the preparation for liquid of scouringing and bleaching, scouring and bleaching and wash air drying steps, complete bafta low temperature and scouring and bleaching single bath process
Technique, it is described to comprise the following steps that：
（1）Scouring and bleaching the preparation of liquid：By 5-10g/L30% hydrogen peroxide, 0.5-3g/L penetrating agent JFCs, 0.5-3g/L sodium metasilicate, 1-
2.5g/L alkaline agents, 0.5-1g/L catalyst are mixed, and are stirred；
（2）Scouring and bleaching：Adjust the pH of liquid of scouringing and bleaching with pH buffer solutions, bafta be immersed in liquid of scouringing and bleaching at 20-25 DEG C, with 5 DEG C/
Min speed is warming up to certain temperature, is incubated 40-60min, and the bath raio of the bafta and liquid of scouringing and bleaching is 1:5-20；
（3）Washing is air-dried：Scouring and bleaching after end, bafta is alternately washed 2 times with 50 DEG C of warm water and 25 DEG C of cold water, it is natural in atmosphere
Air-dry.
Further, the step（1）Middle alkaline agent is one kind in sodium hydroxide, sodium carbonate, sodium acid carbonate；Catalyst is
Heme iron enzyme, mixing speed is 100-200rpm.
Further, the step（2）In scouring and bleaching liquid pH value for 6.5-7.5, temperature is 50-70 DEG C.
Beneficial effects of the present invention are as follows：Concise combined with bleaching is used single bath process technique by the present invention, and in single bath process
Middle addition hydrogen peroxide catalyst promotes hydrogen peroxide to produce peroxide hydrogen radical anion, reduces the decomposition of hydrogen peroxide；The present invention
It just can complete to scouring and bleaching under neutral, cryogenic conditions, reduce temperature and pH needed for reacting, reduce the damage of cotton fiber, together
When reached the purposes of energy-saving and emission-reduction.
