Woven goods are normally preset or the setting is carried out during the thermosol dyeing process. 1.5 Dimensional stabilization via addition of polyester Figure 2 Dimensional Stabilization using Polyester Where subsequent finishing of the knitted goods is not required presetting leads to a slight improvement in pilling behavior. Fabrics which are resin finished do not require this type of pre
Fabrics constructed of highmodulus hightenacity lowshrinkage polyamide fabrics are continuously dyed with acid dyes by applying at ambient temperatures a pad bath solution formulated to provide a continuous film on the fabric surface followed by drying and dry heat curing or thermosoling at elevated temperatures to fix the dye molecules inside the fibers.
Pad thermosol pad steam process It is the process for continuous dyeing of polyestercotton blends. It may be either disperse reactive combination or disperse vat combination. Following is the flow chart. Pad with disperse and reactive dyes infrared drying thermosol pad steam washing off drying.
Dyeing the item twice each time using the appropriate dye type for the fiber types in the polyester blend. Step 2 Select a Polyester Dye. As discussed above select the appropriate dye for your needs. If you want a simple and easy process to dye your items stick with something like RIT DyeMore or Jacquard iDye Poly.

Dye can be used afterward. No carrier is required. Fabric is processed in open width form so natural feel of fabric do not get disturbed. No crease formation. Lower ...
Dying polyester can be a harder or trickier process than with natural fabrics. There are far fewer dyes that will work with polyester fabrics than with natural fibers like cotton. Some of the other dyes depending on which brands they are can work with polyester/cotton blends but the success of the project would depend largely on how much ...
and to compare the results with those of two bath dyeing. Polyester/cotton 5050 blend fabrics were studied using dichlorotriazine based reactive dye and compatible disperse dye. The one bath one step method was used to shorten the dyeing process increase yield and reduce the utility and chemical cost.
This brochure describes the Econtrol TCA process for continuous dyeing of polyester/cellulose and blends with elastane e.g. Lycra . It is a onebath process which combines the successfully established Econtrol process for cellulosic fibers with a thermosol dyeing of polyester in alkaline medium.
The thermosol process is the third method. In it disperse dyes dissolve rapidly in the polyester fibre producing dyeing with good fastness properties when heated to approximately 200C. Dyeing...
Both these ranges of dyes can give the same colour and good buildup properties on both fibres of the blend fabrics by the thermosol process in the presence of specified solvents e.g. polyethylene glycols within a certain range of molecular weight Dybln and derivatives of a polyalkylene oxide Cellestren . The amount of solvent depends mainly on the dye concentration and also on the proportion of cotton in the blend and on the liquor pickup.
After drying the fabrics were treated by the thermosol process under the condition of 200 C/3min for the nylon 6 and 190 C/3min for the triacetate fabrics. Medium color depth was obtained for all dyes. The treated fabrics were soaped and subsequently their dyeing fastness such as light laundering chlorine and sublimation was evaluated.

Recycrom can be applied to the fabrics using various methods such as exhaustion dyeing dipping spraying screen printing and coating. Recycrom is applied as a suspension while most dyes are used as a chemical solution and hence can be easily filtered from water thus reducing the environmental impact.
Add 2 tsp 2.5 ml of Synthrapol 1 tsp 5 ml citric acid crystals or 11 tsp 55 ml white distilled vinegar diluted dye carrier NSC from Step 6 and finally the mixed dye from step 6. If the dye recipe uses dye carrier in the process you need to prepare a rinse pot.

In a process for dyeing drying thermosoling washing and drying a polyester material the improvement comprising thermosoling the polyester material in an infrared oven under tension and subsequently quenching the polyester after the thermosoling but before the polyester material contacts any holding or restraining roll. 2.
Abstract A dyed fabric and apparel constructed therefrom that has a high degree of colorfastness and a soft hand formed by the process comprising the steps of applying dyestuffs directly to a polyester fabric that has been pretreated with a wicking agent and fixing the dyestuffs to the fabric by heating the fabric at between about 350 degrees Fahrenheit for between about 90 and 120 seconds whereby the finished fabric has a crocking index of at least 4.0 and a soft hand.
The Thermosol process with disperse dye is a continuous dyeing process introduced by Du Pont in 1949. A dispersion of the disperse dyes is padded onto the polyester fabric. The material is then dried using a hot flue air dryer or by infrared radiation the latter usually giving much less migration of the dye.
Dyeing sequence of polyester cotton is the combination of polyester and cotton dyeing process. For this reason this dyeing process is called double part dyeing process. In this dyeing process polyester part is dyed first than cotton part is dyed. Dyeing flow chart of polyester cotton is given below

This dyeing process is developed by Du Pont Corporation in 1949. here at sufficient temperature the fibres are soften and their internal structure is opened polymer macromolecules vibrates vigorously and dye molecules diffuse in in fibre. It requires only a few seconds to 1 min and temperature about 200230 C. The sequence of operation is
Wet the fabric so it is well saturated to help the color attach more easily to the fibers. Mix the dye solution in a dye pot over a heating surface such as a stove and add the fabric. Slowly bring the temperature to 120 degrees. Stir the fabric frequently for a more even coat.
Item can remain in dye bath from 10 minutes up to one hour. If dyeing polyester or a polyester cotton blend keep the fabric in the dye bath for at least 30 minutes to ensure that the color takes fully. Nylon tends to dye very quickly and much darker than other fibers so the actual time needed in the dye bath is less.
Raise the temperature to 60 c. Dyeing is carried out for 20 min.Then soda ash of required quantity is added continue the dyeing for 90 min and then after treatment is given. 12. Conclusion We have learnt by this assignment how to make Blended dyeing its dyeing procedure recipe factors affecting the choice of dyeing methods etc.
Previously we reported that polyester fabric could be dyed with vat dyes by the pad / dry / thermosol process at 210oC adding sodium hydrosulfite and sodium hydroxide.
In this process the fabric is padded with the dye solution with 6080 0 C and then fabric is passed through drying chamber. Then the fabric is padded with chemical NaOH Salt . Then the fabric is passed through a chamber at 102 C for 30 sec.
