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
