The common damage forms of automotive interior leather and the functional positioning and definition of the scope of application of repair fluid products
Various forms of damage will occur to automotive interior leather in daily use. Correctly identifying the type of damage and selecting a matching repair fluid product are prerequisites for effective repair.Common leather injuries include surface scratches, color wear, gloss loss, slight cracks and local stain penetration.Surface scratches refer to the damage to the surface coating of the leather but the underlying leather fibers are intact, which are manifested as fine linear traces; color wear is more common in areas of frequent contact, and the surface coloring layer is gradually thinned or even worn through, revealing the light color of the bottom layer; gloss loss is the aging of the surface coating after long-term use, losing its original luster; slight cracks appear at the bending of the leather, which is a comprehensive manifestation of coating aging and leather fiber fatigue; local stain penetration is oily or water-based dirt penetrating into the leather interior, which is difficult to remove with conventional cleaning.
For different forms of damage, leather repair fluid products have a clear positioning of repair functions.Leather repair fluid is a kind of functional liquid material. The main components include resins, colorants, penetrants and additives, which can penetrate into the surface of the leather, replenish the lost ingredients, and restore the color and texture of the leather.For surface scratches, the repair solution can penetrate into the gap between the scratches, fill it in and fuse with the surroundings; for color wear, the repair solution can supplement the coloring layer to restore the color evenly; for gloss loss, the resin component in the repair solution can form a new gloss layer on the surface; for minor cracks, the penetration and filling of the repair solution can close the cracks and prevent further expansion.The scope of application of repair fluid covers most mild to moderate injuries caused by daily use. For severe damage and structural damage, it needs to be repaired with other products such as repair cream.
The advantage of leather repair fluid lies in its simplicity of operation and the comprehensiveness of the repair effect.Compared with the injury repair process that requires multi-layer construction, the repair fluid usually only needs to be wiped or sprayed to complete the repair, which is suitable for the owner's own operation and daily maintenance.While restoring color, the repair solution often has both moisturizing and protective functions, which can supplement the leather with the necessary oil components to prevent dryness and aging.For the interior leather of old vehicles, regular use of repair fluid for maintenance can effectively delay the leather aging process and maintain the good condition of the interior.Therefore, leather repair fluid is not only a repair product, but also a daily care product, which plays a unique role in the maintenance of automotive interiors.
