CONTINUOUS LONG-FIBER NON-WOVEN FABRIC, LAYERED BODY, AND COMPOSITE MATERIAL AND PRODUCTION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2020/179584

Kind Code:

A1

Abstract:

Provided are a continuous long-fiber non-woven fabric having excellent compactness, and a composite material having excellent external appearance and produced using the non-woven fabric and a production method therefor. The continuous long-fiber non-woven fabric is formed using a fiber, the main component of which is a non-crystalline thermoplastic phenoxy resin. The thermoplastic phenoxy resin has a weight average molecular weight of 10,000 to 100,000 and a glass transition temperature of 100°C or lower. The continuous long-fiber non-woven fabric may be a melt-blown non-woven fabric or a spun-bonded non-woven fabric, for example.
