Investigation of the quality properties of open-end spun recycled yarns made from blends of recycled fabric scrap wastes and virgin polyester fibre

摘要

Recycled fibre obtained from fabric scrap wastes is characterized by its low quality properties in terms of inhomogeneous fibre type and non-uniformly distributed short fibre lengths, both of which negatively influences the production process and the quality of the recycled yarns made from it. One of the common ways to utilize recycled fibre in yarn production is to blend it with virgin fibres. In this research article, the quality properties of the open-end spun recycled yarns produced in different material and spinning parameters from blends of recycled fabric scrap wastes and virgin polyester fibres are investigated. As material and spinning parameters, yarn count, blend ratio, waste type, waste origin, twist coefficient and rotor diameter are selected and their effects on the quality properties of the recycled yarns are evaluated through statistical methods. Statistical results reveal that especially blend ratio, yarn count and twist coefficient significantly affect the quality properties. In general, incorporation of virgin polyester fibre to recycled fibre tends to bring about improvement in yarn quality.
