In this study, the influence of loop length on microcapsule loading capability of Interlock knitted fabrics was investigated. Eudragit RSPO microcapsules containing Ibuprofen were made by solvent evaporation method. Five levels of loop length on Cotton Interlock knitted fabric were 2.81, 2.83, 2.87, 2.96, 3.05 mm and three levels of this on CVC 60/40 Interlock knitted fabric were 2.65, 2.80, 2.95 mm (both series of fabrics had yarn count of Ne40/1). | Journal of Science & Technology 122 (2017) 067-072 The Influence of Loop Length on Microcapsule Loading Capability of Interlock Knitted Fabric Dao Thi Chinh Thuy, Chu Dieu Huong* Hanoi University of Science and Technology, No.1 Dai Co Viet Str., Hai Ba Trung, Hanoi, Viet Nam Received: February 21, 2017; Accepted: November 03, 2017 Abstract Microcapsule application is a modern method of finishing functional textiles. Microcapsule loading capability of fabric, a very important value for evaluating the efficiency of this method, depends on many factors including fabric structural parameters. In this study, the influence of loop length on microcapsule loading capability of Interlock knitted fabrics was investigated. Eudragit RSPO microcapsules containing Ibuprofen were made by solvent evaporation method. Five levels of loop length on Cotton Interlock knitted fabric were 2.81, 2.83, 2.87, 2.96, 3.05 mm and three levels of this on CVC 60/40 Interlock knitted fabric were 2.65, 2.80, 2.95 mm (both series of fabrics had yarn count of Ne40/1). Microcapsules were impregnated onto fabric by wet coating. Microcapsule loading capability of fabric was determined by the change in mass of fabric after microcapsule impregnation. The regression equation expressing the influence of loop length on microcapsule loading capability was approached by least squares method. The results showed that for both series of fabrics, microcapsule loading capability depended on loop length by a quadratic function with high coefficient of determination (0.9÷1). Keywords: Interlock knitted fabric, loop length, surface density, porosity, microcapsules. in Rib fabric and proportional to loop length in Interlock fabric. But until now, there haven't been any equations that describe the relationship between loop length and microcapsule loading capability of knitted fabric. Such equations are really necessary for design process of functional textiles using microcapsules. 1. Introduction Application of .
