Benefits of technology

This patented technology provides an improved way to make decorative materials that have better strength without adding harmful chemicals or odors during production. These composites also release their own flavor over time due to its unique structure.

Problems solved by technology

This patented technical problem addressed in this patent relates to improving the quality and durability of synthetic fibre products such as carpets that use odor emitting agents like citronella oil (C10H14O) for enhancing their scent experience during wearings made on them. Existing methods involve adding perfume oils overcomes these issues due to lack of stability and slow releasing mechanism. Therefore there needs to develop new ways to encase flavour ingredients onto fiber surfaces while maintaining good physical strength and flexibility.

Abstract

The invention provides a jasmine essence capsule for leather. The jasmine essence capsule is composed of raw materials by mass percent: 2%-4% of jasmine essence, 12%-16% of ethyl acrylate, 3%-6% of twain-20, 4%-8% of ethyl orthosilicate, 0.8%-1.5% of azodiisobutyronitrile, 2%-5% of vinyltriethoxysilane and the balance deionized water. The nanometer jasmine essence capsule with an ethyl acrylate/nanometer SiO2 composite material as a wall material is prepared through a microemulsion polymerization method and a sol-gel method, the average grain size ranges from 60.03 nm to 117 nm, the coating rate reaches 95%-98%, and the sweet loads reach 32%-39%. The prepared jasmine essence capsule is sprayed to the leather and can enable the lather to have fresh and natural jasmine fragrance.
