Manufacturing method for water-repellent knitted fabric and the resulting water-repellent knitted fabric

Manufacturing method for water-repellent knitted fabric using dyed yarn immersion and heat setting

This technology involves manufacturing water-repellent knitted fabric by immersing dyed and knitted fabric into a water-repellent solution to ensure deep penetration, followed by partial drying, heat setting, washing, and final drying.

Knitted fabrics typically have large gaps between fibers, making it difficult for water-repellent solutions to penetrate evenly or adhere securely to the fabric.

By utilizing a process of partial drying and heat setting after immersion, this technology ensures the water-repellent solution is firmly bonded to the yarn, providing durable water repellency that withstands repeated washing.

Key Features:

• Yarn dyeing process followed by a knitting process to produce the knitted fabric.
• Immersion process where the knitted fabric is soaked in a water-repellent solution to ensure penetration into the yarn structure and coating on the surface.
• Partial drying process where the fabric is dehydrated to a level of 50% to 80% after immersion.
• Heat setting process where the partially dried fabric is heated to firmly bond the water-repellent solution to the knitted fabric.
