패션 신소재로서의 지사 특성에 관한 특허 분석과 활용 방안 = Patents Analysis and Application on the Characteristics of Paper Yarn as New Fashion Materials

다국어 초록 (Multilingual Abstract)

Paper yarn is currently developed as multi-functional and eco-friendly textile materials. Conventionally, manufacturing system of paper yarn comprises three steps: the first step for forming paper sheet with bast fiber or abaca, the second step for slitting the sheet into a paper tape yarn and the third step for twisting tape yarn into paper yarn. Most of patents related functional paper sheet, slitting apparatus, paper yarn, and composited yarn are registered and applied around Korea and Japan. To produce a tenacious paper sheet, the longitudinal fiber
orientation, elastic reinforcing agents, and bast fibers with aspect ratio(fiber length/fiber diameter), 150 or more are mostly preferred.
Since the breakage of paper yarn happened frequently during knitting or weaving process, several methods such as adhesion of wax and oil, steam treatment, and wet crepe process could be supplied to the tape yarn.
Also, to prevent the shrinkage and rupture of paper yarn and to increase color fastness to light, some methods for preparing a union fabric and composited yarn with other yarns, or modifying fabric structure may be applied.
From the fact that paper yarn has excellent property in humidity control function, air permeability, absorbency, antibiotic, and deodorant efficiency, the paper yarn can be fairly used in specific end-uses as well as fashion materials or home textile materials.
