Title:
MULTI-LAYER WOVEN KNITTED FABRIC
Document Type and Number:
WIPO Patent Application WO/2022/176797
Kind Code:
A1
Abstract:
With a view to providing a fabric that produces little fiber waste caused during washing and that has excellent water absorption and fast-drying properties while exhibiting heat-retention properties equivalent to those of the conventional raised fabric materials, a multi-layer woven knitted fabric according to the present invention: includes, in yarns constituting at least one of the outer layers of the fabric, a composite synthetic fiber that is of a side-by-side type or eccentric sheath-core type and that comprises two types of polymers, which are component A and component B; and is configured, in a specific embodiment, to have a knitted fabric design of having a small number of interlacing points between yarns in the outer layers containing the composite synthetic fiber. Accordingly, the expression of fine crimps through heat treatment of the composite synthetic fiber is maximized and a fine heat insulating layer is formed, whereby it is possible to provide a multi-layer woven knitted fabric that produces little fabric waste during washing and that achieves heat retention properties equivalent to those of the convention raised fabric materials.
