Introduction Material Research
Tired of HOLES in your t-shirts?
Tired of YELLOWING t-shirts? Tired of that permanent mildew smell?
• The TAG indicates whenthe t-shirt has gonethrough 20 wash cycles Normal wear,
yellowing, and fiber& yarn breakagebegin after 20washes.
• The TAG indicates it’s timeto throw away the t-shirt.
What if…?
Final Prototype

Design of Experiment
Results and Conclusions
• Great affinity to cotton• Low washfastness• Inexpensive
Direct Dyes
• Not compatible with cotton• Medium washfastness• Soluble in water
Acid Dyes
• Increases viscosity• Ideal for acid dyes• Colloid powder: water soluble
Thickener
• Reduces color loss from fabric• “Glue” to hold dye to fabric• Trumoda Emulsion Polymers
Binders
• Factors: binder, type of binder• Factor Level:• Type of binder: Trumoda 741, Trumoda
721• Binder: 1.5 g, 4.5 g• Response: L* value
DOE Terms
Different prototypes Pass/Fail
Direct dyes different colors Fail
Direct dyes with hot wash Fail
Direct dyes with cold wash Fail
Green direct dye w/ sodium bicarbonate Fail
Blue direct dye with binder 721 Fail
Blue direct dye with binder 741 Fail
Brown acid dye with binder 721-4.5 grams Fail
Brown acid dye with binder 741-4.5 grams Fail
Brown acid dye with binder 721-1.5 grams Pass
Brown acid dye with binder 741-1.5 grams Fail
Acknowledgements Results from current machinery
• Dye paste was able to print on the machine• Did not successfully get absorbed by the fabric due
to difference in pressure and amount of dyeapplication
• Shows relation between L* values and amount of binderafter 20 washes for each type of binder. Since lines are not parallel there is interaction

Human Error
Dye does not work if applied by
current machinery
Does not fade exactly
in 20 washes
•Find exact levels of factors to meet 20 washcriteria exactly
•Adapt dye to work with current machinery•Create new industrial process for application
