Toray
Conjugate spinning technology for fabric like Japanese paper

 
Unlike conventional fabrics, Camifu can match the Japanese paper features. The conjugate spinning technology, Nanodesign was used to develop a flat C cross-sectional shape that delivers a precise arrangement of 3 different polymers. It has arranged polymers with different heat shrinkage properties in special shapes on the left and right of a flat cross-section, with a soluble polymer in the fiber center.

Toray heat treated polymers on the left and right side of the fiber to bend along the fiber length. This, coupled with a flat shape, creates a unique twist and stretch. Varying the arrangement and shape of the polymer with adjacent fibers generates different torsional structures for each yarn, resulting in a yarn bundle structure containing complex voids.
A yarn bundle structure produces a random unevenness in the fabric texture so it feels like hand-made Japanese paper. Single yarns comprising polymers with different colorations and dyeability cover the fabric without aligning. Camifu is eco-friendly, as one of its polymer is recycled from film scraps.

A hollow structure inside the fiber was created by placing a soluble polymer within, augmenting yarn bundle voids from filament twisting during relaxing and weight reduction process on textile. This hollow portion imparts a lightness and resilient feel to the fabric. A precisely designed slit keeps functional agents within the fiber, making it possible to incorporate a range of features in the fabric.
