Today's KNOWLEDGE Share : Teijin Frontier develops high-performance fabric with 100% recycled polyester

Today's KNOWLEDGE Share

Teijin Frontier Develops A New High-Performance Polyester Fabric With A Natural Fiber-Like Texture And Appearance

Teijin Frontier Co., Ltd., announced today that it has developed a new high-performance polyester fabric, which combines the elegant appearance and texture of natural fibers made of yarns of random thickness with advanced functionalities such as cool touch, anti-stickiness, quick dry, opacity and ultraviolet (UV) protection.


The newly developed fabric is produced from a unique, four-lobed, flat cross-section yarn with random thicknesses, achieved through Teijin Frontier’s proprietary spinning technology. These thickness variations create pleasing irregularities in appearance and a dense texture similar to those of natural fibers. To support circularity, The newly developed fabric is made with 100 percent recycled polyester.

Teijin Frontier plans to make this fabric available to customers for use in casual and fashion apparel for the spring/summer 2026 season.


There is strong demand for textiles that offer a natural and elegant appearance for casual and fashion apparel. At the same time, consumers are looking for value-added comfort features like those found in high-performance sportswear. Until now, it has been difficult to combine these high-performance features with a natural fiber-like appearance and texture.


To solve this issue, Teijin Frontier has created a fabric that offers both the appearance and texture of natural fibers and the comfort of high-performance materials. Using proprietary technology, this fabric is woven or knitted from a four-lobed, flat cross-section full dull yarn with random thicknesses in both the longitudinal and cross-sectional directions. Moreover, to achieve the combination of natural fiber like texture and advanced functionalities, Teijin Frontier also adopts special dyeing and finishing technology and post-processing techniques.


Delivering High Performance:

The newly developed fabric delivers the following performance properties to enhance comfort and wearability:

Quick dry: Capillary action wicks away perspiration via grooves on the fiber surface.

Cool touch: Full dull yarn contains titanium oxide promotes a cooling sensation as heat is transferred from the skin to the fiber, flat cross-sectional shape increases the skin contact area.

Anti-stickiness: Random thicknesses of the yarn forms irregularities on the surface of the fabric and prevents its adherence to the skin.

Anti-transparency and UV protection: Full dull yarn and the four-lobed flat cross-sectional structure produce a light-scattering effect that creates opacity and helps to block UV radiation.


Teijin Frontier plans to begin sales of this fabric from fiscal year 2025 and aims to sell 250,000 meters by fiscal year 2027.

Today's KNOWLEDGE Share : CERN Scientists turn lead into gold

Today's KNOWLEDGE Share

CERN Physicists Observe Conversion of Lead into Gold

Near-miss collisions between high-energy lead nuclei at CERN’s Large Hadron Collider generate intense electromagnetic fields that can knock out protons and transform lead into fleeting quantities of gold nuclei.


Transforming the base metal lead into the precious metal gold was a dream of medieval alchemists.

This long-standing quest, known as chrysopoeia, may have been motivated by the observation that dull gray, relatively abundant lead is of a similar density to gold, which has long been coveted for its beautiful color and rarity.


It was only much later that it became clear that lead and gold are distinct chemical elements and that chemical methods are powerless to transmute one into the other.

With the dawn of nuclear physics in the 20th century, it was discovered that heavy elements could transform into others, either naturally, by radioactive decay, or in the laboratory, under a bombardment of neutrons or protons.

Though gold has been artificially produced in this way before, physicists with the ALICE Collaboration at CERN’s Large Hadron Collider (LHC) have now measured the transmutation of lead into gold by a new mechanism involving near-miss collisions between lead nuclei at the LHC.


Extremely high-energy collisions between lead nuclei at the LHC can create quark-gluon plasma, a hot and dense state of matter that is thought to have filled the Universe around a millionth of a second after the Big Bang, giving rise to the matter we now know.

However, in the far more frequent interactions where the nuclei just miss each other without ‘touching,’ the intense electromagnetic fields surrounding them can induce photon-photon and photon-nucleus interactions that open further avenues of exploration.


The electromagnetic field emanating from a lead nucleus is particularly strong because the nucleus contains 82 protons, each carrying one elementary charge.

Moreover, the very high speed at which lead nuclei travel in the LHC causes the electromagnetic field lines to be squashed into a thin pancake, transverse to the direction of motion, producing a short-lived pulse of photons.


Often, this triggers a process called electromagnetic dissociation, whereby a photon interacting with a nucleus can excite oscillations of its internal structure, resulting in the ejection of small numbers of neutrons and protons.


To create gold (a nucleus containing 79 protons), three protons must be removed from a lead nucleus in the LHC beams.

“It is impressive to see that our detectors can handle head-on collisions producing thousands of particles, while also being sensitive to collisions where only a few particles are produced at a time, enabling the study of electromagnetic ‘nuclear transmutation’ processes,” said ALICE spokesperson Dr. Marco Van Leeuwen, a physicist at NIKHEF.

Today's KNOWLEDGE Share

ECHA launches revamped Classification and Labelling Inventory

The C&L Inventory includes information on more than 4 400 EU-level harmonised classifications and seven million classifications notified or included in REACH registrations. Altogether, the inventory includes data on around 350 000 substances.


The integration of classification and labelling information into ECHA CHEM follows the initial launch of the database in January 2024, which featured information on over 100 000 REACH registrations submitted by companies. The new inventory is designed to help users easily locate the classification with the highest agreement and to bring clarity on the source behind the classification information. It incorporates recent regulatory developments, such as the new CLP hazard classes and is built with stability and growth in mind. 


In this first version, the classification information is accessible in a visual format per substance with complementary approaches, such as application programming interfaces (APIs), being explored in future releases. 


Mercedes Viñas, Director of Submissions and Interaction, said: 

“This is an important milestone in further developing a comprehensive database for all chemical data gathered by ECHA. The redesigned C&L Inventory comes with an enhanced user interface and simplifies access to classification information for users.


Mike Rasenberg, Director of Hazard Assessment, added:

“Hazard classifications are the cornerstone of regulatory risk management of chemicals. The redesigned C&L inventory improves the clarity on the current and upcoming mandatory classifications harmonised at the EU level, helping companies to prepare and implement the required safety measures.

Today's KNOWLEDGE Share:High packing pressure reduce warpage

Today's KNOWLEDGE Share

How could that be, since the packing pressure is not going to really change fiber orientation ?


The mechanism is a bit more subtle.


GF induced warpage is linked to the mismatch of "shrinkage" of the glass fiber vs. the shrinkage of the matrix. Such mismatch creates a much bigger shrinkage perpendicular to the fibers because in the parallel direction, the fibers can better "resist" the pull from the matrix.


So why would a higher packing pressure reduce warpage ?


Think about it. If you could increase the packing to the point where the matrix would hit nearly zero volumetric shrinkage (check the PvT curves, it is possible although usually unreasonable) then the matrix would not want to shrink anymore, and the conflict with the glass fibers (which also don't want to shrink much) is gone !

So...no warpage !


So, remember, the more you pack a GF filled part, the less it will warp (at least from the anisotropy effect, differential shrinkage is another story).


Of course there are limits to how much you can increase the packing without running into other issues...
