Production Process of the PU Shoe Lining Leather

The surface laminating process of PU shoe lining leather is a crucial step in its production, directly affecting the product's appearance, feel, and durability. Regarding the description of "performing two processes of surface laminating for PU shoe lining leather," although specific details may vary depending on different manufacturers and process requirements, it can generally be summarized into the following two main steps:

First Process: Basic Laminating

1. Material Preparation:
   • Select suitable PU resin as the laminating material, adjusting the formula based on the product's performance requirements (such as wear resistance, hydrolysis resistance, and hand feel).
   • Prepare the base fabric, typically non-woven fabric, plain weave fabric, twill fabric, or elastic fabric, as the carrier for the PU resin.
2. Coating and Laminating:
   • Uniformly coat the PU resin onto the base fabric, which can be done by methods such as knife coating or roll coating.
   • During the coating process, pay attention to controlling the thickness and uniformity of the coating to ensure the quality and performance of the final product.
   • Send the coated base fabric into an oven for drying and curing to tightly bond the PU resin to the base fabric.
3. Surface Treatment:
   • Perform surface treatment on the dried PU leather, such as embossing or sanding, to improve its appearance and feel.
   • If necessary, apply a protective agent or waterproofing agent on the surface to enhance the product's durability and waterproof performance.

Second Process: Reinforcing Laminating or Decorative Laminating

1. Reinforcing Laminating:
   • If further improving the strength and durability of the PU shoe lining leather is required, a reinforcing laminating can be performed on top of the first process.
   • Select PU resin or other suitable materials with high strength and wear resistance as the reinforcing layer.
   • Uniformly coat the reinforcing layer onto the PU leather obtained from the first process and dry and cure it.
2. Decorative Laminating:
   • If the product needs specific decorative effects, such as patterns or colors, decorative laminating can be performed in the second process.
   • Use PU resin or other decorative materials with patterns or colors, applying them onto the surface of the PU leather through methods such as knife coating or printing.
   • Dry and cure the decorative layer to ensure it tightly bonds to the PU leather and presents the desired decorative effect.

Notes:

• Throughout the laminating process, strictly control process parameters such as temperature, time, and coating thickness to ensure the stability of product quality and performance.
• The materials and chemicals used should comply with environmental protection requirements to avoid polluting the environment.
• After laminating, the PU shoe lining leather should undergo quality inspection, including appearance inspection, hand feel testing, durability testing, etc., to ensure it meets the design requirements.

In summary, the two processes of surface laminating for PU shoe lining leather mainly include basic laminating and reinforcing or decorative laminating. Through these two processes, PU shoe lining leather with excellent appearance, feel, and durability can be produced.
