AI Technical Summary
Technical Problem
Existing textile products are difficult to recycle completely when using latex or synthetic polymer adhesives, and their tufting bonding strength is insufficient, failing to meet the mechanical load requirements of high-end applications.
Method used
Polyester particles with a particle size of less than 1000 nm and polyester materials with an HLB value of 7.6 to 10.5 are used as adhesives to prepare aqueous dispersions, ensuring that the polyester materials are uniformly dispersed in textile products and form high-strength tufted bonds.
Benefits of technology
It achieves easy recycling and high tufting bonding strength in textile products, making it suitable for high-end applications. The preparation process is simple and can be carried out on conventional equipment.
