Abstract

Hanji paper yarn is a multi-functional and eco-friendly textile material that is excellent in the function of humidity control, absorbency-quick dry, antibiotic, deodorant property. Also, its structural characteristics similar to the filament yarn, brings a unique texture and comfort to the touch. In the present work, two kinds of Hanji tape yarn, HTY-23 ($13g/m^2$, 2.0 mm) and HTY-30 ($13g/m^2$, 1.5 mm), were prepared and the tape yarn had a yarn count of 23 Ne and 30 Ne, respectively. In addition, we designed most fibers of Hanji paper to be aligned parallel to the machine direction, allowing for a more favorable processing parameter with regards to the production of fine and tough Hanji paper yarn. The twist number showing a maximum breaking stress of HTY-23 and HTY-30 were 600 tpm and 800 tpm, respectively. Especially, the fluff hardly existed on the surface structure of Hanji paper yarn. In addition, yarn irregularity, yarn defective, and the hairiness of Hanji paper yarn were evaluated. Generally, there was no difference of yarn irregularity between HTY-23 and HTY-30 at the twist number showing the maximum breaking stress. The values of yarn irregularity were remarkably low compared to that of cotton spun yarn. Furthermore, yarn defective of Hanji paper yarn showed a similar tendency to the yarn irregularity.
