Overview

Product overview

The polyester solid/hollow conjugated staple fibre (PSF) production line is a complete line used to produce polyester staple fibre — both solid and hollow conjugated types — from PET/polyester waste and post-consumed PET bottles.

The finished fibre serves polyfill wadding, premium pillows, cushions and quilts, automotive non-woven carpet, spinning yarns and geotextiles, while hollow fibre in particular delivers superior bulk and resilience. The line has two parts: a spinning line (vacuum/crystallizing drying, extrusion, filtering, spin beam, quenching, winding, drafting and can-traversing) and a finishing line (creel stand, stretching, stacking and crimping, heat-setting and baling). The fibre reaches a tensile strength of 3.5–4.5 gm/Denier across 1.5–33 Den and cut lengths of 44–102mm as required, with a flexible capacity of 3,000–50,000 T/Y and a typical case being a 60 TPD line.

Vina Nonwoven is the authorized Yongxing representative in Vietnam: we advise on line configuration and capacity for exactly the fibre you plan to produce, with local installation, commissioning, maintenance and warranty.

Q & A

Frequently asked questions

What raw material does this PSF line use?

The polyester staple fibre is produced from recycled PET/polyester waste and post-consumer PET bottles, not virgin PET chips.

What's the difference between solid and hollow fibre, and when is each used?

The line produces both solid fibre and hollow conjugate fibre; hollow fibre gives better resilience, making it suited to pillows, cushions and quilts that need loft and shape recovery.

What capacity range does the line cover?

The line's capacity ranges from 3,000 to 50,000 T/Y; a typical example is a 60 TPD (tonnes per day) line.

What products is the PSF fibre used for?

The fibre is used for cushions, pillows, quilts, toys, jackets, mattresses, automotive/speaker felts and non-woven carpet, polyfill wadding, geotextiles, filter fabrics and acoustic materials.

How do I get a quote for this PSF line from Vina Nonwoven?
