super zero®

“Munenshi yarns” are made by combining the left twisted cotton yarns with water-soluble yarns, which is then twisted again in the opposite direction. "super zero®︎" is the result of further twisting the “munenshi yarns” to the right, then handled through hydrothermal treatment. This process melts the water-soluble yarns and expands the cotton yarns, which allows airflow through the pockets, creating an airy and one-of-a-kind yarn composition.

technology

01
twist
Combining left twisted yarns with water-soluble yarns, which is then twisted again in the opposite direction.

02
dissolve
Undergo hydrothermal treatment to melt the water-soluble yarns.

03
expand
Due to the water-soluble yarns melting, the cotton tries to return to its original direction, which results in the thread expanding in size.

04
aerate
This allows air to enter the gaps between the threads, creating a yarn composition with high absorbency that retains its fluffy texture.

advantages

Like "super zero®︎", “munenshi-yarns” also use water-soluble yarns and are twisted in the opposite direction from its original, resulting in an almost untwisted composition. "super zero®︎" twists the yarns harder, which is the significant difference from “munenshi-yarns” and its unique characteristic. "super zero®︎" retains its twisted composition, there are no problems such as shedding or inferior durability, which are the drawbacks of “munenshi-yarns”.

The outstanding characteristics of "super zero®︎" is possible due to the vacuum steam press, that has been devised after many years of trial and error, This step is vital to make highly twisted, almost permed-like yarns to be suitable for knitting and weaving. The yarns are ironed out without melting the water-soluble yarns before undergoing the hydrothermal treatment. This ironing technique is unique to "super zero®︎" and differentiates its compositions from others.
