Abstract
The invention discloses a kind of cotton polyester fabric reducing dye microcapsules pad dyeing dyeings, including following technique：S1, configuration dye liquor, dye liquor is configured to after reducing dye microcapsules, pH buffer, penetrating agent JFC and dispersing agent NNO are added water；S2, dye liquor is padded, according to bath raio 1:20 40 pad cotton polyester fabric to be contaminated in dye liquor, are sealed with reducing solution at cloth feeding, pad 60 DEG C of the temperature ＜ of slot with water seal mouth, an immersing and rolling at cloth outputting, pick-up is 90 100%；S3, reducing solution is padded, cotton polyester fabric is directly padded in reducing solution；S4, reduction decatize, quick decatize is carried out using saturated vapor；S5, oxidation, are aoxidized using preoxidation.The cotton polyester fabric reducing dye microcapsules pad dyeing dyeing not only has good level-dyeing property, the high advantage of color fastness, and simple for process energy saving.
Description
Technical field
The present invention relates to reduction stain technical fields more particularly to a kind of cotton polyester fabric reducing dye microcapsules pad dyeing to contaminate
Color technique.
Background technology
Reducing dye dyeing is always that people contaminate cotton class dyeing product most with its excellent resistance to rinsing, color fastness to daylight
Love.International printing and dyeing market incrementally increases reducing dye dyeing ramie cotton fabric demand at present.But since its requirement is high.Using one
As fluid dip dyeing mode carry out the dyeing of ramie cotton fabric reducing dye and cannot be satisfied this requirement at all, and exhaust process level-dyeing property and
Color fastness is poor.And ramie cotton fabric dyeing is carried out using " pad dyeing of conventional reduction dye suspension " mode, in bottoming drying mistake
Cheng Zhong causes ramie cotton fabric bottom to whiten, client can not receive since dyestuff is to looped pile top migration.
The 1980s mid-term, Japan attempts microcapsules being used for field of textiles for the first time, and American-European various patents are not yet
Disconnected to occur, China is still in initial stage of development at this time.Heat resistance microcapsules are made in reducing dye or disperse dyes, it is excellent using its

In the present invention, the cotton polyester fabric reducing dye microcapsules pad dyeing dyeing, for the cotton polyester fabric
Surface features, dyeing are broadly divided into, dye liquor configuration, reducing dyes, dye, dye oxidation four-stage on dyestuff, first,
Dye liquor configuration is carried out using the microcapsules of reducing dye in the present invention, the microcapsules of the reducing dye are with sodium alginate
With chitosan be composite carrier (wall material), compounding reducing dye (core material), calcium chloride be crosslinking agent, and it is cloudy to pass through sodium alginate
Ion and divalent calcium ions chelate form spatial network macromolecular, and reduction is fixed in three-dimensional network, are formed internal for sky
Between reticular structure core-shell structure copolymer reducing dye microcapsules；Since the microcapsules of reducing dye have excellent slow-release function, because
This can control sequential reduction, oxidation rate, and thus dyeing speed is also controlled, and the technique has good even
Effect is contaminated, simultaneously because microcapsules isolation performance, can prevent dyestuff from forming spot to cotton/wash fiber contamination, and micro-
Capsule is effectively isolated performance and control release performance, essential levelling agent and dispersion in being dyed instead of reducing dye
Agent, not only eliminates auxiliary agent, it is prior be still inherently eliminated the chroma pollution and COD brought due to auxiliary agent,
BOD loading makes only to contain microcapsules in dyeing waste-water, as long as simple filtration recycling, advantageous to environmental protection,
Greatly reduce harm of the dyestuff dust recycling to environment and human body.
In addition, in the present invention, when the dye liquor that the textile pad is formed by reducing dye microcapsules, by dye liquor
The control for padding mode, temperature, pick-up etc. is conducive to microcapsules molecule and is spread to cotton polyester fabric, and then to cotton polyester fabric
Carry out uniform adsorption；In order to avoid carrying out cotton polyester fabric dyeing using " pad dyeing of conventional reduction dye suspension " mode, the present invention
The knot dyeing technology, is dried without bottoming, fabric fluid-tight mouth is directly just impregnated reducing solution, and restore and contaminate through decatize, thus
The defects such as aberration, migration cloth cover floating caused by not only greatly reducing bottoming drying, but also energy consumption can be reduced；Hereafter
In order to avoid the hygrometric state dyestuff fall off it is more, increase reducing solution reducing property, the present invention in also pass through select sodium hydrosulfite, dioxy
Change thiocarbamide and reduced sugar compounds the reducing agent to be formed, wherein since reduced sugar is modified through glyoxal solution, reducing power obtains
Greatly improve, with sodium hydrosulfite, thiourea dioxide be used as reducing agent, obtained it is a kind of stablize at low temperature, under higher temperature and also
The reducing solution that former power constantly discharges, therefore fabric can be padded at a lower temperature, you can ensure reducing solution uniform adsorption,
And when the fabric carries out reduction decatize at relatively high temperatures, it can greatly improve the coloring of fabric, entire cloth cover
Even dyeing, reproducibility and color fastness are fabulous, and substitute partial insurance powder due to the use of reduced sugar and thiourea dioxide,
COD value in dyeing sewage effluent can be significantly reduced, environmental-protecting performance is greatly strengthened；Finally, in being aoxidized to fabric, control
Oxidation solution source when weaving object aoxidizes and temperature, thus to obtain uniform oxidation effectiveness, using soaping twice, removal is floating
Color, to keep color and luster, it is hereby achieved that higher color fastness.
