초록
Recently, interest on wellness of consumers have increased and the market of eco-friendly fashion products in daily life is expanding. Therefore, it is necessary to develop knitwear materials for the textile fashion industries. A fine count cotton is used for knitted fabrics such as sweaters and jerseys because of its excellent stretchability, absorption and high sensitivity, etc. In this paper, mechanical properties of composite yarns made of a fine cotton yarn(210 Nec) and functional PET(hollow PET 65 De, antibacterial PET 75 De) manufactured by two-for-one machine were investigated. Also, the physical properties of the knit fabric specimens were analyzed using composite yarns. On the evaluation of fineness, tensile strength and strain, the composite yarns showed outstanding tensile strength and strain with increasing the functional PET yarn content. The tensile strength of knitted fabrics was excellent with increasing contents of hollow and antibacterial PET yarns. On the other hand, strain of knitted fabrics showed tend of decrease. The dimensional stabilities of knitted fabrics were appeared to good results with increasing the hollow and antibacterial PET yarn content. The color fastness of washing, abrasion and sweat of knitted fabrics after dyeing showed 4.5 grade, but light fastness was appeared 3-4 grade. It is expected that a fine cotton/functional PET composite yarns and their knitwear will contribute to consumer satisfaction and expansion of knitwear market.
Abstract
Recently, interest on wellness of consumers have increased and the market of eco-friendly fashion products in daily life is expanding. Therefore, it is necessary to develop knitwear materials for the textile fashion industries. A fine count cotton is used for knitted fabrics such as sweaters and jerseys because of its excellent stretchability, absorption and high sensitivity, etc. In this paper, mechanical properties of composite yarns made of a fine cotton yarn(210 Nec) and functional PET(hollow PET 65 De, antibacterial PET 75 De) manufactured by two-for-one machine were investigated. Also, the physical properties of the knit fabric specimens were analyzed using composite yarns. On the evaluation of fineness, tensile strength and strain, the composite yarns showed outstanding tensile strength and strain with increasing the functional PET yarn content. The tensile strength of knitted fabrics was excellent with increasing contents of hollow and antibacterial PET yarns. On the other hand, strain of knitted fabrics showed tend of decrease. The dimensional stabilities of knitted fabrics were appeared to good results with increasing the hollow and antibacterial PET yarn content. The color fastness of washing, abrasion and sweat of knitted fabrics after dyeing showed 4.5 grade, but light fastness was appeared 3-4 grade. It is expected that a fine cotton/functional PET composite yarns and their knitwear will contribute to consumer satisfaction and expansion of knitwear market.
