The oily oysters of the fur (fat, oiling) are processes in which the scented fur is treated with grease or a fatliquor to impart a certain amount of oil to the fur to impart a certain physical, mechanical and performance properties to the pelt. It determines the softness, foaming and elasticity of the fur, affects the physical and mechanical properties of the leather, such as strength, elongation, tapping rate and breathability, and imparts a good sense of mercerizing and lightness to the suede leather.
The purpose of fatliquoring is to use grease to form a lubricating oil film between the leather fibers to disperse the fibers and increase the mobility between the fibers, thereby making the leather soft, folding and increasing the elongation of the leather. Rate, rate.
Tingjiang company's KT oil TJFUR 3Q66 is equipped with another oily kicking oil, which shows superior penetration and perfect compatibility. It perfectly reflects the concept of 1+1>2. The softness, foaming, and elasticity of the skin affect the physical and mechanical properties of the leather, such as the strength, elongation, yield, and breathability of the leather, and give the suede leather a good sense of mercerizing and lightness. Particularly outstanding performance.
Oil raft process control points:
1. The oil tanning agent must contain unsaturated fatty acids and animal oils containing iodine and low acid (≤15). At present, the compound kappa oil is the main product.
2, the air is necessary for oil sputum, the oil is oxidized to become a sturdy substance. Excessive oxidation is also not conducive to tanning.
3, the pH value has no obvious effect on oil sputum, the use range is 6.0-9.0, but 7.0-7.5 is the best.
4. The temperature of the oil raft does not exceed 45 °C, and there is a risk of shrinkage of the skin after exceeding.
