Study Of Dyeing And Composite Finishing Of Sulfone Blended Fabric

The sulfone fiber has excellent heat resistance, high temperature dimensional stability andthermal oxidation resistance than the aramid of1313,because it has strong suction sulfone groupelectron,But due to the sulfone fiber has special molecular structure make it hard to dye underroutine condition.dyeing uptake is low, color is light.so we can make the viscose fiber blendedwith it according to the properties of sulfone fiber.sulfone/viscose blended fabric has a soft,fluffy, good drapability, moisture permeability and good mechanical properties,can meet thequality of high-grade flame retardant clothing,decorative fabric requirements.But theperformance of sulfone/viscose blended fabric will change,Such as viscose fabric flame retardantless poor than sulfone,flame retardant will decline after blend.In addition,sulfone/viscoseblending fabric also has a lot of problems in dyeing,For example,the viscose fiber is dyed withreactive dyes,sulfone is disperse dyeing,two kinds of fiber of two dyes, because of the differentstructure and properties of dye, dyeing conditions difference is large, it is difficult to one bathdyeingIn this paper,based on the different proportions of sulfone/viscose blended fabric as theresearch object,mainly discusses the reactive/disperse dyes neutral bath of sulfone/viscoseblended fabric dyeing with One bath one step,the reactive/disperse dyes pH slip ofsulfone/viscose blended fabric dyeing with one bath one step,and fire proofing/hydrophilic finishof different proportion sulfone/viscose blend fabric.First,discussed the affect of dosage of acetophenone, bath pH,dyeing temperature and timefor sulfone fabric dyeing,the dosage of sodium sulfate, bath pH, dyeing temperature and time onthe Argazol NF reactive dyes of viscose,Identified the parameters of reactive/disperse dyes ofsulfone/viscose blended fabric dyeing,on the base of carrier acetophenone dyeing of sulfonefiber with disperse dye and viscose fabric with reactive dyes,analyze the various factors affect oftwo-component dyeing rate.Among them,disperse dyes is relative stability on dyeing bath pH,in near neutral conditions and acidic conditions had little difference on high temperature dyeing,thedisperse dye diffusion to the inside the sulfone fiber and improve the dye uptake rate with theright amount of carrier,to dyeing balance at the dyeing time of60min,and the washing fastnessand dry and wet fastness are good after the dyed.The sodium sulfate serve as a neutral saltdyeing with reactive dyes,high dosage can increase the dye aggregation in aqueous solution andthe extent of the precipitate of dyeing rate decline.In addition,the reactive dyes can fixation withthe fabric in the neutral and high temperature with the new active groups,,to dyeing balance atthe dyeing time of90min,and the washing fastness and dry and wet fastness are good after thedyed,and the fixation rate were above90%.The reactive/disperse dyes neutral bath of sulfone/viscose blended fabric dyeing with One bath one step has a good Leveling,But the dye has aslight staining,and the results exist certain deviation of uptake rate between two-component withone-component dye.It may be that staining and fiber composition of dye retarding effect.Second,Synthesis pH slip agent SY-Ⅰ could be used in sulfone/viscose blended fabricdyeing with One bath one step,because of the pH contradiction between reactive and dispersedye.Systematically studied the relationship of temperature and pH of dye bath when the differentdosage of pH slip,low temperature (60℃),dye bath pH of about9, high temperature (130℃)when the dye bath pH is between5～6,Application of the M-reactive/AQE-disperse dyes ofsulfone/viscose blended fabric dyeing with One bath one step, the results exist small deviationof uptake rate between two-component with general one-component dye and pH slipone-component dye.Last,Composite functional finishing of different proportion sulfone/viscose blendfabric,Mainly research fire proofing/hydrophilic finish of different proportion sulfone/viscoseblend fabric,Optimize the finishing order and process.Composite finishing selection the flameretardant FPK and hydrophilic agent DP-9993,the finishing order are flame retardant finishfollowed by hydrophilic finish、 hydrophilic flame retardant finish followed by flame retardantfinish and hydrophilic/flame finish in one bath,optimization flame retardant finish followed byhydrophilic finish,the flame retardant agent for60g/L、90g/L、160g/L and the resin for20g/L、30g/L、40g/L when blended ratio70/30、60/40、50/50,different proportion of sulfone/viscosehydrophilic agent dosage are10g/L.
