Abstract
In this study, the effect of surface treatment on tensile property of jute monofilament was investigated. Jute monofilament was treated by two surface treatments; alkali treatment and silane treatment. Surface treatments were carried out in distilled water with l to 5% concentrations at room temperature for two hours. In case of alkali treatment, jute monofilament was washed with distilled water containing 1% acetic acid to neutralize the remaining NaOH molecules. Quasi-static tensile test of jute monofilament was carried out in 1[mm/min]. The Weibull distribution was used to examine dispersion of jute monofilament. As a result, tensile strength and Young's modulus of alkali treated jute monofilament were larger than those of virgin materials. Tensile strength of silane treated jute monofilament was larger than that of virgin. However, the Young's modulus of 5% silane solution treated jute monofilament decreased. Tensile property of alkali treated jute monofilament was affected by a crystal 0f the cellulose. Tensile property of silane treated jute monofilament was affected by the modification of fiber surface.
