Description
Technical field
The invention belongs to shell-fabric dyeing and finishing field, more particularly to a kind of spandex one side of washing shakes a method for cloth improvement color fastness.
Background technology
The synthesis that spandex face fabric is terylene and spandex is washed, the cloth that two kinds of compositions are combined, feel is soft comfortable,
Excellent elasticity.But this fabric in processing because it lacks polar group, under normal temperature condition be difficult by activity, it is acid,
It is scattered to wait dyestuff coloring, therefore relatively common polyester fabric, wash spandex face fabric dye dosage under same depth conditions and be higher by relatively
Much, and because spandex has similar loose structure to terylene, therefore, when being dyed with polyester fiber simultaneously, to scattered dye
Material has adsorptivity, so during to the dyeing fabric of terylene+spandex, can substantially reduce the color fastness of fabric, therefore limit it and answer
Use prospect.And a style is shaken, it is necessary to be dried by steam injection and hot air ring, more aggravate color fastness difficulty up to standard.
The content of the invention
The technical problems to be solved by the invention, which are to provide to wash spandex one side and shake cloth, improves a method for color fastness, this method
Whole flow process has taken into account fabric stability, higher color fastness ensures, it is more beautiful to make to shake a style, after at the same time reducing
Arranging process, reduce energy consumption, no especial equipment requirements；Fabric style after present invention processing is good, the good, good hand touch of elasticity, fastness
Well, anti pilling is good, it is possible to achieve production stability, it is difficult to solve the technology washed in the processing of spandex polar fleece fabric color fastness
Topic.
The invention provides a kind of spandex one side of washing to shake a method for cloth improvement color fastness, including：
Pretreatment procedure, dyeing process, matting, adding assistant process, plucking process, middle shaping process, carding work
Sequence, cropping process, postprocessing working procedures；Wherein, postprocessing working procedures include 170~180 DEG C of high-temperature shapings, reduction cleaning, 130~
140 DEG C low-temperature shaped.
The technological parameter of the pretreatment procedure is：Using 1.5g/l degreasers, 80 DEG C of processing 20min.
The technological parameter of the dyeing process is：Normal temperature adding assistant, 50 DEG C of addition dyestuffs are warming up to, are warming up to 70 DEG C, 70
130 DEG C DEG C are risen to again, are cooled after 130 DEG C of insulation 30min.
The technological parameter of the reduction cleaning is：Using 3g/l cleaning agents and 0.5g/l formic acid, 90 DEG C of insulations are warming up to
30min is washed, and adds 0.3g/l sodium bicarbonate and 1g/l bleeding agents, and 80 DEG C neutralize washing.
The present invention, which cancels, washs spandex face fabric blank pre-setting process, ensure that fabric has the characteristics of high-elastic.Locate after dyeing
Manage high temperature discharge and reduce cleaning additive and with waterside number, (be used to ensure fabric door using high-temperature shaping in second of adding assistant
The stability of width, grammes per square metre and shrinkage), disperse dyes is discharged at high operating temperatures, then enter cylinder again and do reduction cleaning, make high temperature
The dyestuff residual separated out under state cleans up, and enters cylinder wet cloth state while has completed the style that matte shakes grain, finally going out cylinder takes off
Only needed after water low-temperature shaped, you can.Change of the present invention Jing Guo flow, saves and shakes a process, plucking-carding-cropping-high temperature is fixed
Type-enter cylinder reduction cleaning, you can obtain shaking a style.
Beneficial effect
Whole flow process of the present invention has taken into account fabric stability, higher color fastness ensures, it is more beautiful to make to shake a style,
At the same time finishing process is reduced, reduces energy consumption, no especial equipment requirements；After present invention processing fabric style is good, feel
Well, fastness is good, anti pilling is good, it is possible to achieve production stability, solves and washs in the processing of spandex polar fleece fabric color fastness
Technical barrier.
