CiCLO® Polyester Staple Fiber
Durable Polyester. Innovative Biodegradation Technology.

Engineered with CiCLO® technology, our polyester staple fiber combines the familiar performance of conventional polyester with enhanced biodegradation potential under microbe-rich disposal conditions.

Product Overview

Base resin is virgin or recycled PET, spun through melt spinning, drawing, crimping, and cutting into staple. Fineness runs 0.8 to 15 D with standard cuts of 5 to 120 mm. Natural white is the stock color, dope-dyed grades are available, and finished fabric dyes normally with disperse dyestuffs. The CiCLO additive enters at the melt stage under the licensed recipe and leaves the base physical properties of polyester untouched, so no downstream equipment conversion is needed. In storage and in use the ciclo polyester staple fiber keeps full stability and will not degrade early. Biodegradation is triggered only after disposal, in moist, microbe-rich settings.

Technology Principle

Manufacturing this Ciclo Polyester Staple Fiber follows the standard polyester staple route. The CiCLO® additive is fed in as a masterbatch into the PET melt during extrusion, blended evenly, then spun through the spinneret. The biodegradation sites are physically embedded in the matrix, so washing and abrasion do not wash them out.
What actually degrades the fiber is microbes. Ordinary polyester has long, rigid chains that microorganisms cannot easily break into. The embedded sites give them a recognizable nutrient pathway: they settle in, secrete extracellular enzymes, snip the polymer bonds, and eat the fiber layer by layer until it mineralizes into CO₂ and water.
Three things have to happen at once: moisture, microbes, and time. Storage, wear, and home laundering do not provide sustained microbial action, so the Ciclo Polyester Staple Fiber holds up - the same way wool and cotton do in normal use.
Third-party ASTM respirometry tells the story. In seawater (D6691) the Ciclo Polyester Staple Fiber biodegraded 94% over 1,362 days; in soil (D5988) 91% over 1,170 days; in wastewater sludge (D5210) 90% over 952 days; in biologically active landfill (D5511) 91% over 1,278 days. Ordinary polyester in the same tests sat at 0–6%. The biodegradation rate approaches that of wool.

Core Advantages

Performance Intact

Strength, dyeability, hand, and recyclability stay at polyester level, and downstream lines need no conversion.

Stable In Use

Degradation is gated by moisture, microbes, and time together, so the fiber does not break down during wear or laundering.

Measured Biodegradation

Third-party ASTM respirometry data across four environments reached 90% or more, with no microplastics left behind.

Feedstock Flexibility

Virgin and recycled PET routes both work.

Traceability

CiCLO tracers are embedded during extrusion and detectable in finished fabric, with batch-level authentication supporting the ciclo polyester staple fiber supply chain.

Applications

Solutions for Every Industry

Note. Food-contact and medical uses should pass the regulatory tests of the target market before launch. The ciclo polyester staple fiber grade fits existing spinning and web-forming lines in all five categories.

Sports And Outdoor Apparel

Fleece, sweatshirt, and sun-protection fabrics that shed heavily in the wash, where the fiber keeps shed microfibers from persisting in rivers and oceans.

Intimates And Hosiery

Blends with cotton or viscose balance comfort with end-of-life degradation.

Home Textiles

Quilt and pillow fillings plus face fabrics.

Hygiene And Nonwovens

Wipes and disposable hygiene topsheets.

Footwear And Trims

Linings and padding.
