AI Technical Summary
Existing waterproof shoe upper composite processes cannot simultaneously achieve waterproofness, breathability, and strong adhesion. They suffer from problems such as adhesive clogging, easy delamination of the membrane layer, complex production processes, and poor comfort, making it difficult to meet the production requirements of high-quality waterproof footwear products.
The preparation method of double-sided adhesive application of waterproof membrane involves applying adhesive in dots to the upper and lower surfaces of the waterproof and breathable membrane, and then simultaneously hot-pressing it with the outer and inner layers of the shoe upper to form a uniformly distributed dot adhesive layer. This ensures bonding stability and breathability, and simplifies the production process.
It achieves a strong bond between the waterproof and breathable membrane and the shoe upper layer, retains moisture permeability, improves waterproof performance and comfort, simplifies the production process, and reduces costs.
