Obtaining a nano-sized crosslinking chemical by sol-gel technique and its application to fabric

In this thesis, appearance and usage properties of viscose knitted fabric is aimed to improve by sol-gel method as an alternative to conventional method along increasing consciousness of environment in recent years. With this method in small quantities of chemicals is used than conventional method and emission of formaldehyde, whose carcinogenic effect is demonstrated nowadays, is prevented. Viscose knitted fabrics are coated with sol solutions including various silica compounds and abrasion, pilling resistance, dimensional stability, water retention ability of coated fabrics are purposed to develop. In order to improve these properties at the project partner company is used fibric process as a conventional method. And so we compared sol-gel method, is applied at the university, with fibric process, is performed at the company. In addition appearance and usage properties of fabrics are investigated again after multiple washing so that washing resistance of applied method is studied. In order to reduce the cost of silica components is used in sol-gel method different mole ratios are studied. In this way the optimum recipe is determined in terms of cost and performance. Finally the optimum recipe is applied at the company under the operating conditions since therefore in the industry practicability of sol-gel method is researched.
