Preparation of high strength recycled HMLS polyester industrial yarns and development of polyester dipped fabrics
In order to develop high strength recycled high modulus low shrinkage (HMLS) polyester dipped fabric,high viscosity recycled polyester chips were used as raw materials,by reducing melt temperature,increasing spinning speed and other optimization measures,high strength physical recycled HMLS polyester industrial yarns and high strength chemical recycled HMLS polyester industrial yarns with linear density of 1100 dtex were prepared.High strength recycled polyester dipped fabrics were developed by weaving and dipping processes,and compared with high strength virgin polyester dipped fabrics,focusing on their physical properties,fatigue resistance and adhesion performance.The results showed that the strength,dimensional stability,fatigue resistance,and adhesion performance of high strength physical recycled polyester dipped fabrics were relatively poor compared to those of high strength virgin polyester dipped fabrics.However,the properties of high strength chemical recycled polyester dipped fabrics were similar to those of high strength virgin polyester dipped fabrics,and the expected goal was basically achieved.
