Abstract

 Application of different cross-linkers on viscose surface  Investigation of the effects on formaldehyde amount, color, physical properties, softness and wrinkle recovery  Improvements values of free formaldehyde, tensile and tear strength and higher wrinkle recovery Cellulosic-based surfaces, such as viscose and linen, tend quickly to wrinkle, and this is an undesirable property during uses. In this study, it is aimed to investigate their effects on formaldehyde amount, color, tear and tear resistance, modulus of elasticity, softness, and wrinkle recovery angle of surface after applying three different cross-linking chemicals. It has been observed that cross-linking agents had bound to viscose surface, and cross-links were formed between adjacent fibers. Although free formaldehyde values were positively below 75 ppm in all applications, it was seen that color difference and yellowing continued to be a problem. The improvements in breaking and tearing strength were obtained compared to the untreated surface. While lower bending rigidity values were measured for all applications, surfaces had a softer handle after treatments. The higher wrinkle angle values were achieved on the surfaces with an increase in concentration. It was determined that imidazoline gave the best wrinkle angle values among cross-linkers. Figure A. SEM micrographs and FTIR spectrum of cross-linked viscose surface Purpose: The aim of the study is to investigate the effect of different cross-linking chemicals on formaldehyde amount, color, tear and tear resistance, modulus of elasticity, softness, and wrinkle angle of viscose surface. Theory and Methods: In this study, it was chosen viscose fabric and then it was treated by three different cross-linking chemicals, as 80, 115 and 150 g/L of concentration. It was investigated their effects on surface properties after treatments. Results: SEM and FTIR analysis confirmed that the new bonds formed on viscose surfaces after treatments. Conclusion: The use of cross-linking chemicals caused a significant contribution to the physical and wrinkle properties of the viscose surface. The best wrinkle property has been given imidazoline chemical. Considering the fabric properties, 115 g/L application is recommended for all cross-linkers to improve the wrinkle property.
