신합섬사의 저온 거품가호 = Low Temperature Foam Sizing for New Synthetic Filament Yarn

다국어 초록 (Multilingual Abstract)

This study was to investigate the effect of processing variables in the foam sizing of new synthetic filament yarn such as size add-on, size content and drying temperature to improve weaving performance. The new synthetic filament yarn was required to be size at a low temperature. The flaming characteristics of copolyester resin, the influence of viscosity in the size solution, the framable concentration, the abrasion resistence photographs of cross-section of sized yarn were demonstrated. The product such as water dispersible copolyester of relatively low viscosity had a high degree of penetration in the yarn. The strength and elongation of sized yarn were not proportional to the size add-on. The size add-on level was required .to achieve the level of abrasion resistance necessary to weave the yarn. As a result, the properties of new synthetic filament yarn sized using foam were equivalent or superior to those of similar yarn sized conventionally.
