تکمیل ضدلک و ضد‌آب بودن فرش دست‌باف ابریشمی با نانو مواد بر پایه مشتقات سیلیکونی

Persian silk rugs are the most intricate, and often most valuable ones among all hand-knotted carpets. Silk is luxurious, lightweight and soft. Additionally fineness of silk carpet is amazing. Then it is very important to improve its quality and useful life time. During its usage, a typical high quality Persian or Oriental silk rug is exposed to many water-based stains. Although there are now a number of luxury silk carpets on the market, oddly enough they stain easily with the simplest of liquids, i.e. water. That can be bad news for investing goods such as carpets made of this expensive fiber. Getting a water stain out of silk can be tricky, but it is possible. Moisture absorbency of natural silk yarns leads to easy staining of these products by these kinds of pollutants such as tea, coffee, juice, etc. as well as their decreased life time. Textile substrates with super hydrophobic surfaces have attracted much attention for industrial applications and it is a very important resource of advanced materials and new technologies; while this is not applied in hand-woven carpet industry. In this paper hydrophobicity of silk carpets with good compatibility has been improved by treatment with Nano-poly di-methyl silicone. The silk substrates were modified with a silicone compound to achieve low surface energy. Dyed silk by metal complex 2:1 acid dyes as pile yarns and cotton warp yarns applied to weaving silk carpets, and kilims. Treatment by nano-poly di-methyl silicone has been done in low temperature. Evaluation of treatments has been done according to AATCC Test Methods. Durability and stability of surface-treatment of silk carpets were measured too. After washing of carpet and dye-injection on the surface of carpet, contact angle and wet-out time measurements on the silk carpets still show much improved hydrophobic properties. The resultant silk carpet exhibits superior water repellent properties.
