1. Vat dyeing (immersion dyeing)
Process principle: soak the car wiping towel fabric in the dye solution, and make the dye penetrate the fiber through repeated immersion, heating and heat preservation.
Features:
Strong color permeability: the dye is evenly colored from the inside to the outside, the color is full and not easy to fade.
Suitable for complex materials: good compatibility with composite fibers (such as microfiber + polyester), especially suitable for multi-layer structure car wiping towels.
High cost: long time, high energy consumption, large amount of dye.
Good color fastness: washable and resistant to friction, suitable for long-term use.
Applicable scenarios: high-end car wiping towels, focusing on color durability and deep cleaning effect.
2. Pad dyeing (pad dyeing)
Process principle: after the fabric is dipped in the dye solution, it is directly squeezed by the roller, and then fixed by steaming or baking.
Features:
High efficiency: continuous production, suitable for large quantities, low cost.
Mainly surface coloring: the dye is more attached to the fiber surface, and the inner layer penetration is weak.
Color vividness: Bright color in short-term use, but may fade quickly after long-term washing.
Limitations: Poor permeability to composite fibers, which may affect the uniformity of multi-layer materials.
Applicable scenarios: Low-end car wipes, pursuing fast production and cost-effectiveness.
Purchase suggestions
Focus on durability: Choose vat dyeing process, suitable for frequent use or professional scenarios.
Budget limited: Pad dyeing products are more cost-effective, but you need to accept the possibility of fading.
