Beneficial effect: the viscose glue staple in bulk continuous dyeing process designed by the present invention and viscose glue staple in bulk continuous dyeing machine have
Following advantage:
1. shorten the viscose glue loose stock dyeing time, improve staining efficiency, reduce production cost, the viscose glue designed by the present invention
Loose stock dyeing technique is to put into viscose glue staple in bulk raw material in viscose glue staple in bulk continuous dyeing machine, and viscose glue staple in bulk sequentially passes through
Lapping, spray immersion dye liquor, dry, drying, spray immersion fixation liquid, dry, drying, gas steam, washing, dry, packing etc. work
Sequence continuous treatment, directly dyes colored viscose glue staple in bulk from raw material white viscose glue staple in bulk.In dyeing, staple in bulk is paved into 2-
5cm thick fiber blanket passes through chroma tank, and viscose glue staple in bulk sprays through dye liquor, contaminates, and rolling roll roll compacting colouring absorption, due to dye liquor
Concentration is higher, and above-mentioned three kinds of modes are processed, and viscose glue staple in bulk is easy to and dye contacts, thus contaminates fiber relatively on dyestuff
Short.Gas steam and in, viscose glue dye fiber be easier to contact intensification with vapourss, thus the fixation time shorten dramatically it is thus only necessary to
A few minutes to more than ten minutes, compared with conventional cartridge yarn-dyed staple in bulk cake, save substantial amounts of dyeing time.Due to the method for the present invention
Be seriality dyeing it is not necessary to the substantial amounts of back work of inter process, thus save artificial, reduce the consumption of water power equal energy source,
Reduce production cost.
2. viscose glue staple in bulk continuous dyeing machine maceration tank, the dye liquor in pad dyeing groove, fixation liquid all with suction circulating device,
In each groove, liquid all does to viscose rayon blanket after supplementing new liq and sprays, after the washings in rinsing bowl are used for multiple times, through dye
Discharge after the whole process with sewage apparatus, thus the discharge of waste liquid, waste water is all up to standard, environmental protection.
3. low cost, yield is high.Compared with viscose glue staple in bulk continuous dyeing process soaks cylinder dye with tradition, dyeing time is to pass
The 1/15 of system, and between each operation, do not need auxiliary operation, cost substantially reduces.
