PET Extrusion Line, 35 to 40 Tons/Day, 3 to 25 Denier, 2-Step Process

Description

  1. Overview
    1. The plant was used in fully continuous operation, 24/7 for 350 days per year.
    2. Input materials included bulk materials of all types: pet bottle flakes, resins/granule chips, regrinds of various types of materials, and agglomerates from the European market and worldwide.
    3. Regenerated fibers produced were between 3 den and 25 den, suitable for automotive, geotextiles, technical textiles, and all general textile sectors, always in 100% recycled fibers.
    4. Predominantly the line was producing a high quality black staple fiber.
    5. The plant operates in a 2-step process.
    6. The plant consists of two spinning lines (line c and line d) and one finishing line including a bale press (semi-automatic baling press).
    7. The plant consists of ce conform machine parts and complies with the safety regulations of the eu.
    8. Necessary operating personnel: 6-7 operators per shift (depending on company organization and qualification of the employees).
    9. Accessories include spinneret packages, spinnerets, cutting wheels, and auxiliary/packaging material.
    10. The plant is as much automated as possible.
    11. The equipment is running under siemens s 7.
    12. Energy screening/monitoring through "enefco" system.
    13. All existing technical documentation will be handed over.
    14. As the plant was operated by ourselves, we can provide all necessary process data.
