Cotton and Polyester blend is an example of chemically different blend and Cotton and Viscose is physically different blend because both are cellulosic.About Polyester Cotton BlendPolyester Cotton blend is very popular blend in our textile. Both of them are same in their nature. And this is very comfortable blend as well as widely used.Polyester-Cotton blend 65/35 means amount of polyester part in the blend is 65% and cotton is 35%. Both are all most near staple length and spun to make blended single ply yarn. The fabric which is made by this blend is known as the 65/35 poly-cotton blend or P/C fabric.20Importance of Using Disperse & Reactive Dyes in a P/C Blended FabricShade matching % of Disperse & Reactive dye is very good.Now a days Reactive dye is mostly used for cotton & Disperse dye is mostly used for polyester.For P/C blended fabric, usage of Disperse & Reactive dyes are quite easy & cost effective.Uneven shade variation problem of blended fabric can be overcome by using of Disperse & reactive dyesWhat types of effect occured during dyeing of blended fabric?Solid dyeing - both fibers are dyed the same hue and to the same depth.Reservation - one fiber remains undyed.Tone-on-tone - one fiber is dyed a deeper shade than the other.Cross dyeing - each fiber is dyed a different and contrasting hue.Now here is the name of some Disperse & Reactive dyes which is mostly used to color P/C blend fabricCommonly used Disperse dyesTrade nameManufacturerOriginForonSandozSwitzerlandTerasilCiba-GeigySwitzerlandDispersolICIUKSamaronHoechstGermanyCommonly used Reactive dyesTrade nameManufacturerOriginProcionI.C.IU.KCiba cronCibaSwitzerlandRemazolHoechstGermanyLevafixBayerGermanyReactoneGeigySwitzerlandProcess Flow Chart of P/C Blend Dyeing With Disperse & Reactive dyesGray FabricScouringDryingHeat settingMercerizationDryingPET dyeReduction clearingDryingSingingCotton dyeWashingSoapingWashingDryingDyeing Process of P/C Blended Fabric (65/35) 1st , Dyeing of Polyester Part With High Temperature In high temperature dyeing method either material or liquor should circulate. Otherwise dye molecules will not penetrate inside the material. They will stay on surface only. In this method, temperature is kept in between 105-140C and pressure is kept from 0 to 170 kPa. This method is also known as pressure dyeing which is used for highly crystalline synthetic fibers and their blends. This technique causes the fiber to swell even more than which achieved at 100C temperature. So that dye molecules penetrate the fiber polymer system. It eliminates the need of carrers.

Faults Found In P/C Blended Fabric Dyeing Shade Variation Preventive :- Dye selection should be truly and precisely.- Salt & Soda should be used in appropriate quantity.- Correct liquor ratio should be maintained.- Proper time & temperature should be maintained. Crease Mark Preventive :- Apply anti-crease mark agent.- Heavy cloth which is dyed accommodate with machine capacities suggested. Harsh Feeling Preventive :- Proper time & temperature should be maintained.- Dyeing recipe should be maintained properly. Uneven DyeingPreventive :- Dye selection should be truly and precisely.- Salt & Soda should be used in appropriate quantity.- Correct liquor ratio should be maintained.- Proper time & temperature should be maintained.Thank you all with great pleasure and respectFromAshik Md.
