Abstract

The invention discloses a production process of degradable polyester weft knitted fabric. The production process includes steps: raw material selection, degradable polyester yarn preparation, weaving,dyeing, dewatering and finished product forming. A degradable aid is added into raw materials, so that formed yarn is degradable; interlock stitch is adopted for weaving, and the interlock stitch isextremely prone to decoherence when a certain section of the yarn is broken, so that degrading speed of the fabric is increased greatly; conventional polyester does not have degradability, and the fabric can be degraded by 25% in 180 days; when degrading reaches 25%, complete decoherence can be realized due to the interlock stitch; but for fabric with other stitch structure, complete decoherence can be realized only when degrading reaches 50-100%, so that decoherence speed is increased greatly.

Description

technical field [0001] The invention relates to a production process of knitted weft-knitted fabric, in particular to a production process of degradable polyester knitted weft-knitted fabric. Background technique [0002] With the progress of society, the chemical fiber industry has developed greatly, and the demand for fiber products is also increasing. Therefore, higher requirements are put forward for the performance of fiber products. Fiber products are developing in the direction of high comfort, high function and high environmental protection. With the increasing pressure on the ecological environment and the continuous improvement of people's environmental awareness, degradable fiber fabrics will be the development direction of fabrics in the future, and have gradually become the research focus of the fabric industry. Key points and hot spots, at present, the material performance and degradation effect of degradable fabrics in my country are still relatively poor. Co...
