Overview

Product overview

The PET high-tenacity low-elongation (HT/LE) fibre production line is a line used to produce polyester (PET) staple fibre with high tensile strength and low elongation, made from PET/polyester waste and recycled PET bottles.

What sets it apart from ordinary PSF is a tensile strength reaching ≥5.7 gm/Denier — markedly higher — together with a denier range extending down to 0.9 Den, suiting applications that demand strength and dimensional stability. Bottles are sorted, crushed into 12–15mm flakes, alkaline-washed, vacuum/crystallizing-dried, then extruded and spun into hollow or solid fibre. The line comprises a spinning line and a finishing line (two-stage drawing, crimping, heat-setting, cutting and baling), producing fibre with cut lengths of 44–102mm, elongation of 40–60% and 3–5 crimps per cm. Capacity is flexible, from 3,000 to 50,000 T/Y, with 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 your fibre type, with local installation, commissioning, maintenance and warranty.

Q & A

Frequently asked questions

What raw material does this line use?

The line spins high-tenacity, low-elongation PET staple fibre from PET/polyester waste and recycled PET bottles — bottles are sorted, crushed into 12–15mm flakes, alkaline-washed and dried before spinning.

What fibre deniers can this line produce?

Fibre can be produced in deniers of 0.9, 1.2, 1.5, 3, 6, 10, 15, 18, 22, 25 and 33 Den, with cut lengths of 44, 51, 64, 76 or 102mm as per customer requirement.

What are the tensile strength and elongation of the finished fibre?

Tensile strength is at least ≥5.7 gm/Denier and elongation is 40 to 60%, with 3 to 5 crimps per cm.

What is the production capacity of this line?

Capacity ranges from 3,000 to 50,000 T/Y; a typical example is a 60 TPD (tonnes-per-day) line.

How can I get advice on the right configuration and a quote for this line?

Since the line configuration (capacity, fibre denier, accompanying equipment) depends on each plant's needs, please contact Vina Nonwoven via hotline or Zalo for consultation and a specific quote.
