Properties of hybrid yarn made of paper yarn and filament yarn

摘要

A paper yarn is recently spotlighted as a new textile material due to its inherent excellent properties such as antibiotic, deodorant, moisture retaining, and absorbency-quick drying properties. However, its poor flexibility and low elongation cause some disadvantages of cut-off and difficulty in tension control in the knitting process. To prevent those disadvantages of the paper yarn, in this study, a production method of hybrid yarn with other synthetic filament yarn was conducted. Four types of the hybrid yarn with paper yarn and polyester and nylon filament yarns were prepared. The maximum breaking stresses of the hybrid yarns were shown at twist number of 600 tpm and 700 tpm of paper/polyester and paper/nylon yarn, respectively. Also there were relatively different morphologies of the hybrid yarns with twist numbers. These facts originated in a stable integration of each single yarn constituting the hybrid yarn. Due to the reinforcing effect of the filament yarn, the hybrid yarn showed an increment in the maximum stress and strain, but a decrease in initial modulus compared to single paper yarn. In addition, irregularity and defective of the hybrid yarn were evaluated with the surface structure of the yarns. The hybrid yarn having maximum breaking stress showed good knitting ability and excellent surface appearance of its knitted fabrics.
