Abstract

Nanotechnology modifications play a major role in textile industry due to extraordinary properties exhibit in fabrics due to nanomaterials. It offers different functionalities namely self-cleaning, wrinkle resistance, flame retardancy, protection from UV radiations or antibacterial property. Further, it is important to maintain cleanliness in aircraft upholstery always but the airliners have to bear a considerable amount of money to clean up the aircraft upholstery. Interestingly, nanotechnology can provide stain repellence property for fabrics in aircraft upholstery. This study covers a method of developing a stain repellent fabric which was stable even after 25 standard laundering conditions. In this study nanotechnology was used to modify a cotton fabric with stain repellant property. After nanotechnology modification, the surface wettability of the treated fabrics was characterized by static water contact angle measurements before and after 25 washes carried out under standard laundering conditions. Similar testings were carried out for the untreated fabric samples. The static water contact angle for the treated fabric was 161° with the recovery of 97.5% after 25 washing cycles. SEM and AFM micrographs were used to analyze the coatings. Further, the stability of hydrophobicity in the modified cotton fabric after 25 washes was also tested for tea, coffee, and water solutions which are vulnerable stain types in aircraft upholstery. It clearly proved that the modified cotton fabric even after 25 washes showed hydrophobicity for tea, coffee, and water. Therefore, it could be concluded that the developed modified cotton fabric can consider to be used as an aircraft upholstery.

Highlights

Researchers have been working to mimic the biological surfaces such as lotus leaves, butterfly wings, mosquito eyes, moth eyes, red rose petals, gecko feet, desert beetle, and spider silks which exhibit excellent hydrophobicity.[1,2,3,4,5]The surfaces with hydrophobic and/or super hydrophobic properties have received a great scientific and industrial attention because of their wide range of applications.[4,6] Hydrophobic or super hydrophobic surfaces can be made by chemically treated methods to manufacture products in various domains, namely in automotive, aerospace, marine applications, and textiles
butane tetra carboxylic acid (BTCA) was used as the binder to improve the washing durability of cotton fabric which was achieved hydrophobicity by sol-gel technology combining TiO2 sol and stearic acid
The results showed that the BTCA binder and stearic acid treated cotton fabric could effectively improve the washing durability of cotton fabric, while TiO2 sol only and stearic acid only coated cotton fabrics showed weak hydrophobicity without washing and complete hydrophilicity after 25 washes
