“…PU, acrylic, nitrocellulost, and casein finishes are a few types of leather finishes that are frequently utilized. PU finishing agents are superior to complete bodies in terms of their mechanical qualities, strong adhesion, nice hand feel, and film performance when compared to other leather finishing agents [5]. One of the most important phases in the tanning of leather is the finishing treatment.…”

This final project aims to explain the cowhide leather through a pull-up mill finishing technique based on colorant variation. The raw materials used were crust cowhide, with an average thickness of 1.43 mm, which was divided into two treatments in samples 1 and 2. Sample 1 was completed by finishing using liquid dye dyes, while sample 2 with liquid dyestuff and pigments. The results of the trial were obtained with physical tests and organoleptic tests. The physical test results for dry rubbing resistance in experiments 1 and 2 showed results that were following consumer standards, while wet rubbing resistance in sample 1 and 2 showed loss of color so they did not comply with consumer standards. The organoleptic test was done by giving questionnaires to respondents who were experts in the fields. The results of the organoleptic test in sample 1 were uneven color, poor coverage of defects, strong pull-up effect, moderately even mill grain effect, limp skin, fairly even skin density, and slightly raised lid paint. While on sample 2, the color was even, the defects were covered, the pull-up effect was quite strong, the mill grain effect was uneven, the skin was limp, the skin density was even, and the covering paint on the lid was small raised. According to the physis and organoleptic results, leather produced by colorant variation used liquid dyestuff close to the standard for pull up mill article.

“…By coating, dipping, laminating, and other processes, PU and PVC materials are applied to the artificial leather, followed by buffing or polishing to create a leather-like pattern and texture. The flexibility and durability of artificial leather make it suitable for various industries, allowing it to be applied to the surface of injection-molded parts, expanding their range of applications [8][9][10].…”

This study investigates the surface properties and adhesive strength of polypropylene (PP) in order to enhance the bond between PP injection-molded specimens and polyvinyl chloride (PVC) synthetic artificial leather. Plasma, primer, and flame treatments were applied to the surface of each specimen prepared using the two types of injection molds. The surface morphology, surface roughness, and contact angle were analyzed, and peel-strength analyses and a morphological inspections of the peeled specimens were performed. The peeling strength of the PP injection molding was measured, followed by a morphological examination of the peeled specimens. The plasma and flame treatments improved the peel strength, and the plasma and flame treatments changed the rough exterior to a hydrophilic surface, improving the peel strength. In addition, the primer treatment exhibited a lower peel strength than did the other treatments. This confirmed the low adhesion of the primer to the hydrophobic PP surface. The outcomes of this study can be employed across a multitude of industries that require improved adhesion for PP injection molded products.
