Change of Surface Characteristic of Cotton and Polyester Fabrics Treated with Silicone Resin by Washing and Subsequent Heat Treatment

Abstract

:It is commonly known that water repellency of the fabric treated with fluorocarbon resin brings about a decrease by the washing and recovers by the subsequent heat treatment. In this article, effect of the water repellency was investigated on the cotton and polyester fabrics treated with silicone resin. Silicone resin has been widely used in the textile finishing as the softening and water proofing agents. The fabrics were treated with a silicone resin, Poron MR (Shinetsu Chemical Co.) and then washed and subsequently heat treated. Although the water repellency increased by the resin treatment, it decreased by the washing apparently and recovered a little by the heat treatment. The effect of the heat treatment was small comparing with that of the fluorocarbon resin. Furthermore, in order to investigate the change of the surface chemical composition of the fabric, ESCA analysis was carried out. The O 1s and Si 2p intensities were almost unchanged by the washing and following heat treatment. The Si 2p showed also the same tendency. As a mechanical property of the treated fabric, KES shearing and bending hysteresis parameters, modulus and hysteresis width of the silicone resin treated cotton and polyester fabrics decreased by the heat treatment after washing. Therefore, the treatment is effective at improving the softening of the fabric in water repellent finish.

Water repellency improvement of cellulosic textile fibers by betulin and a betulin-based copolymer

“…Afterwards, some waxy materials like fluorinated silanes are added to make the textile waterproof (Shi et al 2013). Unfortunately, the fluorinated silanes are expensive and contaminated wastewater is generated during the treatment process (Lee et al 2005;Mazurek et al 2001;Yahaya et al 2001).…”

Surface modification of cellulose with plant triglycerides for hydrophobicity

“…Ideal water repellent cotton fabrics are hydrophobic on the fiber surfaces to resist water, yet porous to allow moisture transport for comfort. Efforts to reduce the hydrophilicity of cotton have involved surface modification using hydrophobic compounds, such as fluorocarbons (Jiang et al 2005;McCord et al 2003;Sato et al 1994), silicones (Lee et al 2005;Yuen et al 2005) and hydrocarbons (Sawatari et al 1998). These technologies have varying effectiveness and durability in achieving water repellent cotton fabrics although are limited by their sustainability and environmental concerns and cost.…”

Super High Water-Repellent Treatments of Various Kinds of Cloths Using Sol/Gel Method

“…Several kinds of methods have been applied for this purpose [1]. The most common method is coating or laminating of polymer resins containing water-repellent agents such as silicon or fluorine compounds on the clothes [2][3][4]. In recent years, in water-repellent evaluation, it appears the thing over 150°of contact angle of water, we came to call these "super high water repellent" [5,6].…”
