Investigation of some performance properties of spunlace nonwoven fabrics produced by polyester and viscose fibers

Nowadays nonwoven industry has become fairly important in the textile industry due to large application field in many areas. Nonwoven industry has reached the top level day by day in current production amount thanks to increasing its investment, and it keeps continuing its growths in high speed, due to more economical production and productivity in less time all over the world. Nonwovens are produced by different production techniques depending on usage areas. Spunlace nonwoven is referred to one of this production technique of nonwoven, which is obtained by the method of fibers to be interlaced with water jet to each other. Spunlace fabrics are used many areas in our daily lives such as hygienic wipes, diaper fabrics, medical fabrics, and hair towels. In this thesis spunlace fabrics which were produced by polyester and viscose fibers in different blend ratios and weights were investigated performance properties such as thickness, whiteness, absorbency time and capacity, tear resistance, tensile strength and elongation at break. Effect of fabric weight and blend fiber on these performance properties were examined. Obtained results were investigated in statistical terms and ANOVA analysis was determined. In addition, correlation analysis was performed to examine the relationship between fabric weight, blend ratio of polyester - viscose fiber and performances properties. According to obtained test results it was determined that fabric weight and blended polyester-viscose fibers were found significant effects on the performance properties. Key words: Nonwoven, spunlace performance properties, statistical analysis, viscose, polyester.
