Polartec®: New technology reduces fiber fragmentation in laundering tests

  • Iconic 200 Series fleece to be the first fabric made from this new process.

Polartec®, a Milliken & Company brand, announces Polartec® Shed Less Fleece, a new milestone in its industry-leading efforts to reduce textile fiber fragment shedding. Shed Less is a process that combines yarn construction, knitting, chemistry, and manufacturing to reduce home laundry fiber fragment shedding by an average of 85%. The first fabric to receive this new technology is the brand’s iconic Polartec® 200 Series Fleece, the modern version of the original PolarFleece® launched in 1981, and in 1993, the first performance fleece knit from yarn made from recycled plastic bottles.

The Shed Less process works by engineering the lofted fibers that give fleece its soft hand the ability to resist breaking and rubbing off during home laundering, cited as one contributing factor to the spread of fibers fragments (commonly referred to as microfibers). Polartec® Shed Less Fleece achieves this while maintaining all of the attributes that continue to make Polartec fleece a staple of midlayer collections - lightweight, breathable and warm.

The brand used the AATCC (American Association of Textile Chemists and Colorists) TM212-2021 test method for fiber fragment release during home laundering. This test was conducted with large sample sizes to account for variability. The testing concluded that Shed Less Fleece reduced fiber fragment shedding by an average of 85% compared to the baseline fabric.

“In 2016 we began looking into how we might test for fiber loss because there wasn’t a lot of research on the issue.” said Aimee LaValley, Polartec Textile Development, Dye and Chemistry Manager. “This led to new products like Polartec Power Air™, new manufacturing processes, as well as our participation in the TextileMission workgroup to study the issue on an interdisciplinary basis.”

TextileMission was a three year collaborative initiative of academia and industry to reduce the impact of textile microplastics funded by the German Federal Ministry of Education and Research. Founding partners include The Association of the German Sporting Goods Industry, Hochschule Niederrhein - University of Applied Science; TU Dresden - Institute of Water Chemistry; Vaude Sport; WWF Germany; Adidas AG; Henkel AG; Miele & CIE; and Polartec, LLC.

Polartec® Shed Less Fleece will be initially launched in the United States and will be available to customers beginning March 1, 2023. The brand plans to apply the Shed Less process to many other industry-leading fabric platforms and manufacturing facilities around the world.

Many years of experience in bi-component spinning

Oerlikon Neumag looks back on many years of experience in constructing bicomponent staple fiber systems. The first system for this fiber type was commissioned as far back as 1995. Oerlikon Neumag offers solutions for the most varied cross-sections, ranging from sheath/core’, ‘side-by-side’, ‘island in the sea’, ‘orange type’ as well as ‘trilobal’. The applications are diverse: from self-crimping fibers, bonding fibers, super-microfibers all the way through to hollow fibers.

The Oerlikon Neumag bicomponent technology is particularly characterized by the extremely robust spin packs that have no expensive wear parts, which considerably reduces the costs here. The reconditioning costs when cleaning the spin packs are kept to an absolute minimum. Add to this the separate temperature transfer option in the spinning beam for the two polymers. As a result, the quality and the viscosity of the polymers can be accurately adjusted in accordance with the respective process requirements.

Oerlikon: Further EvoQuench PA POY systems destined for China

Oerlikon Barmag recently signed contracts for two orders with a total of 120 spinning positions for manufacturing polyamide POY yarn with Chinese yarn manufacturers. What makes this so special is the fact that all positions will be equipped with the EvoQuench radial quenching system for polyamide.

With this, two well-known yarn manufacturers are now committing to the EvoQuench concept to produce polyamide yarn, equipping themselves for the efficient manufacture of microfiber yarns in the process. The benefits of radial quenching vis-à-vis conventional cross-flow quenching when manufacturing microfibers are well-known from polyester processing: manufacturing outstanding quality in a more production-reliable manner, i.e. with fewer yarn breaks, is a convincing argument and makes producing polyamide microfibers considerably more efficient. “Used to create fabrics, the materials feel very pleasant to the touch”, comments Stephan Faulstich, Head of Development POY Process at Oerlikon Barmag, who has held the results of the currently sole operator of such a system in his hands. “I can imagine this will be used above all in the manufacture of sports apparel and underwear.”

The Foron® SP-WF dyes were developed in compliance with “The Archroma Way: safe, efficient, enhanced, it’s our nature”. The approach finds its origin in Archroma’s deep belief that it is possible to make the textile industry sustainable, economically and ecologically.

The new product is at the core of Archroma's Fast Sport, a coloration system for polyester knitted sportswear, providing the best fastness in the shortest possible time with a reduced environmental footprint.
The Foron® SP-WF range which includes primary and ternary color grades has been developed to fulfil the high color wet fastness and performance requirements of sportswear manufacturers and brands.
Moreover, the core ternary color grades enable deep shades at lower dyeing temperatures on sensitive polyester/elastane fabrics without causing excessive fiber damage, saving energy resources and meeting the high fastness demand of leading brand companies.

When using Foron® SP-WF dyes as part of the Fast Sport system, manufacturers can in many cases have the potential to significantly reduce their consumption of time, energy, chemical, and water, as well as their CO2 emissions.

“We see a growing demand for apparel in the sportswear and active wear segment, reinforced with the now installed athleisure trend,” says Mark Dohmen, Head of Archroma’s Competence Center Automotive and Synthetic Dyes. “Consumers want deep color that stays put on the fiber and brands are defining their requirements accordingly. With our Foron® SP-WF, we can offer to manufacturers of sportswear textiles a solution that combines high levels of wet fastness with high productivity and low resource consumption. Because it’s our nature!”

The demand for polyester and man-made fibers is booming as sports and athleisure apparel markets expand rapidly around the world. At the same time, big-name brands that set trends in the sector continue to increase focus on sustainability and performance. As such, this is putting pressure on mills since the current industry standard involves chemically active diffusion accelerants that contain unwanted chemicals and require additional leveling agents and anti-foaming products that may be hazardous to people and the environment.

Developed by Huntsman Textile Effects specifically to meet these challenges, UNIVADINE® E3-3D diffusion accelerant is low-odor, free of benzyl benzoate and other hazardous substances. Part of Huntsman’s range of innovative dyEvolution™ dyeing auxiliaries, it uses Huntsman’s Active Diffusion Technology to enable high-speed dyeing with best-in-class leveling, retarding and migration properties.

“UNIVADINE® E3-3D diffusion accelerant delivers across three key dimensions – diffusion, leveling and migration – for exceptional performance and environmental and economic sustainability. Its environmental credentials offer mills greater processing flexibility and an optimum price-performance ratio,” said Kerim Oner, Global Marketing Manager for Dyeing Auxiliaries at Huntsman Textile Effects. “We expect this latest offering to change the way that the industry dyes polyester and blends while meeting stringent environmental standards.”

UNIVADINE® E3-3D diffusion accelerant has a high affinity to polyester, causing the fiber to swell and increasing the diffusion of the disperse dye, even at lower temperatures. Multiple leveling mechanisms then slow down the exhaustion rate to ensure safe, defect-free dyeing. Finally, as the dye bath heats up, the product’s strong support for disperse dye migration ensures the dye molecules are evenly absorbed.

As a result of this cutting-edge diffusion technology, UNIVADINE® E3-3D diffusion accelerant can be used to successfully dye polyester fibers in tightly wound or high-density yarn/beam dyeing and is suitable for jet applications without the need for anti-foaming products. Reducing exposure to high heat, its Active Diffusion Technology minimizes the potential to damage the elastane in polyester-elastane blends and provides for on-tone dyeing of microfibers. The superior migration support of UNIVADINE® E3-3D diffusion accelerant also increases reproducibility, allowing mills to dispense with additional leveling agents. Polyester, microfibers and blends treated with UNIVADINE® E3-3D diffusion accelerant comply with the requirements of bluesign®, in addition to being suitable for Standard 100 by OEKO-TEX® and an approved input dyeing auxiliary chemical for GOTS (Global Organic Textile Standard) certified textile products*.

Upcycled products with ECONYL® yarn and the PFC-free ecorepel® Bio technology based on renewable raw materials are two ecological highlights of the 2020 Summer Collection, which is being developed and produced in the heart of the Swiss mountains. Color effects turn the functional textiles into exciting multicolors with contrasting reverses and fresh, modern plain colors that can easily be combined.


REGENERATED ECONYL® YARN
The textiles manufactured by Schoeller using ECONYL® yarn made from regenerated material are genuine upcycled products. The ECONYL® Reclaiming Program of Aquafil S.P.A. reduces global waste by collecting recyclable materials from landfill sites and the world’s oceans and returning them into the production cycle. The resulting yarn is no different from conventional textiles in terms of quality and appearance. The Schoeller fabric family with ECONYL® yarn encompasses a complete package with diverse exciting qualities such as ultra-light, bi-elastic schoeller®-dynamic (e.g. for windbreaker blousons), very soft, fine schoeller®-dryskin (e.g. for high-tech shorts) and lightweight schoeller®-WB-400.


ECO-CREATED
New, supersoft soft-shells with ECONYL® yarn are available with different backings and weights depending on the situation. The lightest schoeller®-WB-400 radiates a sense of summer in fresh tones such as melon, oxygen blue or khaki with a smooth jersey reverse in contrasting colors, also made from ECONYL® yarn. A slightly heavier quality surprises in classic black with an elegant, navy blue reverse, while the Bordeaux nuance of the soft-shell with its brushed reverse in stone grey feels warm, soft and cozy. The fluorocarbon-free ecorepel® bio-technology, based on renewable raw materials, offers sustainable water repellence.


WHITE MATTER
The dominant features of summer 2020, alongside sustainable textiles and technologies made from natural materials, are inspired multicolors. The comfortable, multicolored schoeller®-WB-400 qualities produce completely new color effects and create a cheerful look – both for outdoor activities and in urban sportswear. The combination of melon, ocean green and stone grey with white changes the mood of the original colors and lends the textiles an unexpectedly chalky, summery look. Another striking feature is the lightweight, white jersey backing, which is only revealed at second glance.


AUGMENTED ORIGINALS
The presentation of the authentic schoeller®-dynamic qualities is no less lively, ranging from mossy green tones and blue nuances through to the brown variations of tree bark. The multicolors combine perfectly with plain fabrics and are impressively functional thanks to the PFC-free ecorepel® bio-technology, which also provides reliable water repellence. The basic qualities of the lightweight schoeller®-dryskin trousers and jackets are given a touch of elegance in the form of a discreet sheen and fashionable colors. In soft blues and greens, these supple all-rounders are highly wear resistant and offer ideal moisture management through the microfibers on the inside. They also feature ecorepel® bio-technology for water repellence.
