Loepfe presents brand-new yarn clearer generation

Loepfe Brothers Ltd. has been pioneering yarn clearing technology since almost 30 years. At ITMA 2019, the Swiss company presented a brand-new yarn clearer – the YarnMaster PRISMA. With multi-sensor measurement design and new functionalities this next generation of yarn clearers will support spinners all around the world in mastering daily quality control. For the first time, the YarnMaster PRISMA combines new and established sensor technologies in one device.

The Yarnmaster Prisma opens up a new world at ITMA 2019

Four sensor technologies interact intelligently and ensure unprecedented fault visibility and data quality. The unconventional new concept addresses all yarn quality problems related to material and the spinning process with an universal and multi-dimensional approach.

Four sensor technologies

Controlling the contamination in yarns is of greatest importance to the spinners. The YarnMaster PRISMA utilizes a sensor for foreign matter detection based on a brand-new RGB-color measuring technology. The new RGB F-sensor illuminates the yarn in the full spectrum of light, enabling the recognition of even the slightest difference in shade and glossiness in any type of yarn and color. The contamination of raw material with white polypropylene from bale packaging is very challeng-ing. To solve this difficult task, Loepfe developed the P4-Sensor, which utilizes the triboelectric effect. The sensor measures electric charge differences, which are caused during the winding process by different raw materials. This technology is able to detect contami-nation with white polypropylene very reliable. Beyond these, a world first dual measurement for basic clearing is presented to the visitors. On the YarnMaster PRISMA, the two dominant sensor technologies in yarn clearing are integrated into one single sensing head.

This uncon-ventional approach to use an optical and a mass sensor, functioning in perfect harmony, offers unprecedented possibilities and new levels of precision in yarn clearing. The fusion of four sensor technologies into one single sensing head –- YarnMaster PRISMA – guarantees previously unachieved performance and possibilities in quality control during the winding process.

A world of connectivity

The heart of the innovative yarn clearing concept is the simple and intuitive PRISMA operating system. The new PRISMA GUI offers a menu guidance by an intel-ligent wizard and enables straightforward and intuitive operation. As an extra benefit, Loepfe’s data management system MillMaster TOP 2.0 is an integral part of the new YarnMaster PRISMA and complements every Loepfe yarn clearer installation. 100% online monitoring of quality data produced by the yarn clearers reduces the need for routine laboratory tests. Effective online quality management is one of the key success factors for win-ding and results in efficiency and lower costs.

A tradition of innovation celebrated at ITMA 2025 in Singapore

For 70 years, Loepfe has embodied precision, technological excellence, and uncompromising quality. Join us as we proudly celebrate seven decades of innovation at ITMA 2025 in Singapore.

Object Carpet tests production of rPET BCF yarn on Neumag BCF line

In a joint project with Object Carpet GmbH, Denkendorf; the Institute for Textile Technology (ITA), Augsburg; and Next Generation Recyclingmaschinen GmbH (NGR), Feldkirchen, Austria, Barmag investigated the processing of recycled polyester for BCF yarn. The goal was to evaluate the fundamental suitability of 100% recycled carpet material for reuse in carpet yarn production to create a closed-loop system in carpet manufacturing. To date, commercial rPET BCF processes have been based solely on rPET from bottle pellets.

New spinning package with two-step filtration for recycled yarns and more

At the ITM in Istanbul, BB Engineering unveiled its new, patented ValuePack spinning package for the first time, which features a two-stage filtration system. This is particularly beneficial for re-cycling processes. Until now, spinning packs have used either metal powder (“sand”) or filter candles as filter media. Both options are suitable for differ-ent applications, and each has its own specific advantages and dis-advantages.

(NASDAQ: KRNT), a global pioneer in sustainable, on-demand digital fashion and textile production, today announced that USColorworks, a North Carolina-based apparel decoration and fulfillment company specializing in custom and on-demand printing for retail and promotional markets, has expanded its Kornit digital production platform with the addition of Atlas MATRIX and Atlas MAX PLUS systems to deliver high-quality, on-demand apparel across cotton, blended fabrics and polyester.

CovationBio introduces two new bio-based innovations at Functional Fabric Fair New York

Covation Biomaterials LLC (“CovationBio®”) is showcasing its two new bio-based innovations, Xatryx® and Sorona® elasterell-p fiber, at this year’s Functional Fabric Fair in New York City, July 7–9, 2026. Attendees can visit CovationBio at Booth #404 to explore this next generation of bio-based performance materials.

Geotextiles made from recycled materials: GREEN leads the way into the industry

For the industry, recycled materials are creating new opportunities in geotextile production. In the GREEN project, the Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE demonstrates that recycled polypro-pylene (PP), polyethylene terephthalate (PET), and high-density polyeth-ylene (HDPE) can be processed into nonwovens, fibers, and membranes that meet industrial requirements. This creates opportunities for use in existing production lines and new value chains in the geotextile market.

A Penteadora starts up ANDRITZ textile recycling and needlepunch nonwoven lines in Portugal

A Penteadora SA has successfully started up a complete mechanical textile recycling line and a needlepunch nonwoven line supplied by ANDRITZ at its production site in Unhais da Serra, Portugal. This investment enables A Penteadora to expand its industrial capabilities and develop a new generation of solutions based on pre- and post-consumer recycled textiles. The input materials originate from its own production waste and other textile waste streams. Both lines are fully operational, and the first products are expected to reach the market in July.
