Abstract

Hemp paper made from Manila hemp pulp was processed by a traditional Japanese hand-crumpling technique. The applicability of the hemp paper to clothing was examined. Hand-crumpling decreased the dry tensile index of the hemp paper but increased the seam strength index of the sewn hemp paper. A scanning electron microscope was used to observe a piece of hemp paper; the results showed that pulp fibers that were not hand-crumpled suffered brittle fracture without being elongated, while pulp fibers of hand-crumpled hemp paper were elongated and broken by ductile fracture. This implies that hand-crumpling inhibits cracks generated in the stitch from propagating and produces a high stitch strength index. The air permeability and water absorbency of the hemp paper were considerably increased by hand-crumpling. Hand-crumpling considerably improves the softness of Manila hemp paper and enhances its applicability as clothing material.
