“…According to Mustakim et al (2006), if the oil concentration used in the oiling process is small, the oil particles cannot be dispersed evenly, and the oil penetration into the skin fibers is weakened. With such a condition, the leather may get easily torn when pulled.…”

One of the main characteristics of chamois leather is its high ability to absorb water; thus, chamois leather is generally used for cleaning and drying. The usual tanning material for chamois leather is fish oil. However, it makes the chamois leather product have a strong odor. This study aims to evaluate the quality of chamois leather from rabbit skin tanned with corn oil. The treatments included the addition of several corn oil concentrations consisting of P0 (30 % fish oil), P1 (10 % corn oil), P2 (20% corn oil), and P3 (30% corn oil). The results showed that corn oil as a tanning material was able to increase the ash content, elongation, tear strength, and water absorption of chamois skin and was able to reduce oil content, and did not change the tensile strength, color and odor of the chamois leather produced. The quality of chamois leather with 30% corn oil indicated the ash content as much as 3.19%, oil content as much as 7.87%, elongation as much as 94.51%, tear strength as much as 46.47 N/mm, water absorption (24 hours) as much as 279.03%; and tensile strength as much as 9.9 N/mm2. It also produced yellowish-white color with no odor. This quality has met the requirements of the Indonesian National Standard (SNI): 0617521990. The study concludes that 30% corn oil can substitute fish oil to produce chamois leather.

Objective: Indonesian metal casting industry is a labor-oriented industry which involves thermal application in the workplace. Thus, it is essential to protect the workers for any risks during their activity. Leather gloves, as personal protective equipment, need to be manufactured that can prevent the workers from burn injured. The study aimed to analyze the effect of flame retardant addition on finished leather’s physical and mechanical properties for a specific article, i.e. working gloves.Methods: The research used pickled cattle hides and commercial flame retardant as main materials. The leather chemicals used in the process are those which is commonly used to manufacture working gloves leather article. The treatments involved the addition of commercial flame retardant in fatliquoring (2%, 4%, 6% w/w) and finishing process (100 parts, 200 parts, 300 parts). The effect of flame retardant addition on shrinkage percentage, thickness, rub fastness, tensile strength, and elongation at break, were evaluated. Descriptive analysis is applied to describe the properties of the resulted finished leather.Results: The result shows that the addition of flame retardant in fatliquoring and finishing process indicates a variation in the leather’s physical-mechanical properties. The leather, manufactured with the addition of 4% (w/w) in fatliquoring, shrunk 7.65±1.42%, had tensile strength value at 520.48±13.79 kg/cm2, good rub fastness at dry and wet basis (5 and 4/5), elongation value at 52.9±4.09%, and thickness 0.87±0.02 mm.Conclusions: it can be concluded that the use of 4% (w/w) flame retardant in fatliquoring is suggested to be the best formulation to produce working gloves leather.
