For Longer-Lasting Clothes, Science Says Use This Wash Cycle

From the popular mechanics
Procter & Gamble funded a wash cycle length study that found that colder and shorter is better for clothing.
The density and lifespan of the textile dye is independent of problems such as germs and bacteria when washing.
Cold, short washes reduced the dandruff microfibers and the transferred dyes.
University of Leeds scientists - and, as should be mentioned, Procter & Gamble - say that the best way to keep clothing fresh for as long as possible is to use the coldest and shortest wash cycle.
The detergent manufacturer, together with the main author and instructor at the design school, Lucy Cotton (yes), investigated how machine washing causes fabrics to spray microfibers. These lost fibers can cause the garment to age prematurely and weaken fabrics.
In the published article, the researchers used dozens of t-shirts from a specific British activewear seller that represented a handful of brands like Gildan, Russell, and Hanes. The scientists first ran the washing machine empty to ensure that there were no long microfibers inside, and then collected water from the entire cycle to ensure that all newly released microfibers were captured.
The resulting wash water was evaporated, dried completely, and then weighed. The scientists measured the holding and transfer of dyes using "receiver" swatches in each load, measuring their color before and after washing.
After a series of tests with different colors and materials of T-shirts at different washing temperatures and cycle lengths, the results were clear. From the study:
“[T] is a significantly larger color loss, which is observed for the 40 ° C Cotton Short cycle (85 minutes) compared to the Cold Express cycle (30 minutes). These observations provide indications that in a “real” situation, the washing time and the washing temperature increase the loss of color with repeated washing. "
The scientists also measured how much the dye changed from darker to lighter colors, which, for example, causes T-shirts to turn gray and the colors on light prints are dimmed.
“In view of the effect of color transfer on repeated washing, it was observed that in most white recipient tissues, compared to the Cold Express (85 min) for the 40 ° C Cotton Short cycle (85 min), there was a significantly greater color transfer to the tracer fabrics was observed. 30 min) cycle. These observations indicate that in a “real” situation, increasing the washing time and temperature increases dye transfer. "
The same relationship was found for microfibers: higher temperatures and longer periods meant more microfibers, regardless of whether the fabric of the T-shirt was made of cotton or a polyester blend. And the release of these fibers never ceases.
"What is also shown is that a significant number of microfibers are still released from the fabrics during eighth and [16th] washing, suggesting that there is a consistent mechanism of microfiber production and release throughout the life of the fabric Substances exist, "the researchers wrote.
These researchers conclude that the best wash cycle is a modified Leviathan: smoother, colder, and shorter. By reducing time and temperature, we can reduce the amount of microfiber pollution released into the general water cycle, the amount of soap waste and the carbon footprint of our washing activity.
Working with Procter & Gamble, which launched its first cold water detergent for a lot of Ballyhoo in 2005, is a smart financial move. P & G funded the research and added its two cents for its advanced detergents in the press release. However, the research appears in Dyes & Pigments, a peer-reviewed journal, and was Cottons Ph.D. Project - regardless of the company's cold water.
