Abstract

The invention discloses a method for preparing rose-flavored leather. The leather after retanning, dyeing and fatliquoring is subjected to rehumidification treatment at a mass ratio of m leather:m water of 1:7.5-10, and the rotating speed is 600-800 r / min. , when the temperature is 30-40°C, rehumidify for 6-8 hours; use sodium bicarbonate solution to adjust the pH of the system to 5-7, then add rose essence capsules, and the mass ratio is m essence: m leather is 3-8:1, Finally, the temperature of the system is raised to 40-60°C. When the rotation speed is 600-1200r / min, after perfuming for 6-9 hours, the perfumed leather is taken out and dried in a naturally ventilated place to obtain a rose-scented leather. The fragrance utilization rate of the rose-flavored leather prepared by the invention is 34.92%. The rose-flavored leather has a pleasant fragrance and a remarkable rose fragrance. After being placed for 40 days, it still has an obvious rose fragrance and has good fragrance slow-release properties.

Description

technical field [0001] The invention relates to a rose-flavored leather and a preparation method thereof, in particular to a preparation method of a rose-flavored leather processed by a wet processing technique. Background technique [0002] The leather industry is closely related to people's lives. In recent years, aromatic leather has become one of the development trends of functional leather. Combining fragrance with leather is an effective means to improve product grade and added value, and it is also the common demand of consumers and the leather industry.
