Embodiment 1

[0056] A kind of finishing production process of lavender-scented automobile leather

[0057] The Perlnappa FOC Soul low-odor leather blank production process of the selected Perlnappa FOC Soul low-odor leather blank production process for the finishing production process of the lavender-scented automobile leather in this embodiment is as follows:

[0058] Wet white skin peeling→weighing→returning water→retanning→neutralization→filling and dyeing→fatliquoring→color fixing→washing→drum and horse riding→vacuum drying→hanging to dry→softening→vibrating;

[0059] (1) Squeeze and shave the wet white skin: the thickness range is controlled at 1.1-1.3mm;

[0060] (2) Weighing: Weigh the wet white skin after being evenly shaved in the same batch, and this weight is used as the standard for the amount of subsequent chemicals.

[0061] (3) Backwater: use the tanning drum to make the wet white leather fully absorb water, open the gaps between the leather fibers, and facilitate the full ...

Abstract

The invention belongs to the technical field of automobile leather smell improvement, and discloses a coating production process of lavender scent type automobile leather. The method comprises the following steps of leather blank sorting, milling softening, dust removal, lining sealing, bottom coating, embossing, vibration softening, mixed layer spraying, top coating and vibration softening. The invention provides a finishing production process of lavender scent automobile leather in a manner of selecting a fat liquoring agent with extremely low odor to prepare a leather blank, selecting a lavender microcapsule emulsion sustained-release material, and selecting a spherical extinction polyurethane polymer to prepare the lavender scent automobile leather with a sustained-release effect, thereby improving the odor of the automobile leather.

Description

technical field [0001] The invention belongs to the technical field of automobile leather odor improvement, and relates to a finishing production process of lavender-scented automobile leather. Background technique [0002] Automotive interior leather is a comfortable, beautiful, hygienic and durable material that is deeply loved by people. Leather is made of natural cowhide through tanning and finishing. Chemical materials such as synthetic oils and polyurethane resins are used in the processing process. Due to The complexity of the processing technology and the limitations of the existing chemical materials will cause the finished leather to have a typical leather odor problem. The current production process cannot completely solve the leather odor problem. After the leather is produced and stored for a long time, the odor problem will still exist, and the odor problem will be more prominent in the closed environment of the car. The odor of automobile interior has always ...
