Abstract

This study presents basic knitted fabric data on the use of ply yarn with rayon yarn and eco-friendly/ high-valued Hanji yarn. Physical properties (gauge, thickness, burst strength, air permeability, stiffness, Qmax, dimensional stability and surface image) of Hanji 100%, rayon 100% and Hanji/rayon 50:50 knitted fabrics are investigated. The results are as follows. Course direction of gauge decrease in the following order: rayon 100% > Hanji/rayon 50/50 > Hanji 100%. In addition wale direction of gauge decrease in the following or- der: Hanji 100% > Hanji/rayon 50/50 > rayon 50/50. Thickness and air permeability decrease in the follow- ing order: Hanji 100% > Hanji/rayon 50/50 > rayon 100%. Burst strength decrease in the following order: rayon 100% > Hanji 100% > Hanji/rayon 50/50. Stiffness and Qmax decrease in the following order: rayon 100% > Hanji/rayon 50/50 > Hanji 100%. Laundry for dimensional stability is knitted fabric with Hanji/ray- on 50/50 than rayon 100% and Hanji 100% improved using neutral detergent and stable at 20 o C. From sur- face image observation, the cracks of Hanji 100% and fibrils of rayon 100% decrease when using knitted fabric with Hanji/rayon 50/50.
