Modification of leather properties by grafting. I. Effect of monomer chain on the physico‐mechanical properties of grafted leather

Abstract

ABSTRACT:Although leather has a number of desirable properties such as thermal stability and fire retardancey, in addition to high toughness, it has a few drawbacks such as weight, high water absorption, poor soil and rot resistance, and nonuniformity. If these defects are overcome, leather's usefulness would be further enhanced and its competitive position with respect to synthetics would increase. This study reports the physical and mechanical properties of buffalo leather after chemical graft copolymerization with ethyl acrylate, butyl acrylate, and 2-ethyl hexyl acrylate using benzoyl peroxide as an initiator. The optimum conditions for grafting (e.g., monomer and initiator concentrations, temperature and time of grafting, and solvent leather ratio) were extensively investigated. The study achieved outstanding properties for buffalo leather in reduction of water uptake after grafting, especially on using 2-ethyl hexyl acrylate and butyl acrylate monomers. FT-IR and solid 13 C-NMR for leather before and after grafting confirmed the grafting process.

Comparable Evaluation of Leather Waterproofing Behaviour upon Hide Quality. I. Influence of Retanning and Fatliqouring Agents on Leather Structure and Properties

“…In recent, many researches are focused on the leather properties (such as reduction of water uptake) modification by grafting to collagen of different monomers such as styrene and acrylate derivatives [17,18].…”

Synthesis and application of methyl methacrylate/butyl acrylate copolymer nanoemulsions as efficient retanning and lubricating agents for chrome‐tanned leather

“…However, the majority of these researches focused on grafting of various monomers onto leather such as styrene 12 and acrylate monomer derivatives. [13][14][15] Unfortunately, from the environmental and economical point of view, most of monomers used in grafting process are costly in financial terms and dangerous in nature, in addition to the use of organic solvents as a medium for dissolving the monomers during the grafting process, which is not suitable for application in leather industry. For these reasons, the leather industry has issued laws and legislations for reagents used in leather industry must be safe and friendly to environment.…”

"Extraction of Oil and Phenolic Retanning Agent from Avocado Seed"

“…As you age, your body naturally loses its ability to rebuild the collagen, but avocado seed oil helps to naturally restore it. Collagen helps to improve the overall tone of the skin by getting rid of wrinkles, dry flaky skin, cellulite and sclerosis of the skin [16][17][18][19][20].…”
