Abstract
Fatliquoring is an important step of post tanning process of leathermanufacturing where incorporation of self-emulsified oil (lubricant)makes the leather soft. There are several methods which introducepolarity into oil and provide the path where reactive species ofmodified oil can interact with water which leads to form a fatliquor.The aim of this work is to introduce an extra polarity into the fattyacid moiety through chemical modification of castor oil by carbeneintermediate. The spectroscopic characterisation such as FTIR,1H-NMR and 13C-NMR of fatliquor have been carried out. Particle size analysis of fatliquor has also been done. The experimental leathers have been tested for physical strength characterisation such as tensile and tear strength verses control and found to have better properties than control. SEM analysis for morphological study of experimental leather were also carried out which clearly indicates the uniform dispersion of fiber bundles due to the fine distribution of the novel and self-emulsifying fatliquor throughout the matrix.
期刊介绍:
The Journal of the American Leather Chemists Association publishes manuscripts on all aspects of leather science, engineering, technology, and economics, and will consider related subjects that address concerns of the industry. Examples: hide/skin quality or utilization, leather production methods/equipment, tanning materials/leather chemicals, new and improved leathers, collagen studies, leather by-products, impacts of changes in leather products industries, process efficiency, sustainability, regulatory, safety, environmental, tannery waste management and industry economics.
