Unifi: sustainable cationic-dyeable polyester
The filament yarn producer Unifi, Inc., Greensboro, NC/USA, has introduced a new product and further product expansion, consistent with meeting sustainability and performance demands. They are based on the Repreve performance fibers made from recycled PET bottles. These include Repreve cationic-dyeable polyester and expanded Repreve Our Ocean offerings.
Repreve cationic-dyeable delivers 100% Repreve heathers and solids to the market. Offering deeper and brighter colors, as well as improved colorfastness, it can be used in a variety of constructions and across all market segments, from woven to knit to warp knit. The dyeing of these yarns may offer energy savings as compared to some traditional disperse-dyed polyester by utilizing lower temperatures.
Repreve Our Ocean products are made with plastics collected within 50 km of waterways or coastal areas in developing countries or regions. Repreve Our Ocean is concerned with developing recycling programs in areas where plastic is most at risk of entering a marine environment and where there is a lack of formal waste or recycling systems.

Just 4 years later, Karl Mayer acquired all of the shares in the joint venture. Together with Nippon Mayer, the manufacturer set up Karl Mayer Textile Machinery Ltd as its own entity in Changzhou, and in 2005 formed Karl Mayer (China) Ltd. In 2008, the company moved to a new plant with a surface area of 170,000 m². In 2011, the production of knitting machines was expanded to include the manufacture of warp preparation equipment and in the following year, production was expanded again.
The latest milestone in the company’s history was the establishment of KM.ON China – a subsidiary of Karl Mayer’s software start-up KM.ON – in June 2019.
Karl Mayer (China) Ltd. currently employs around 800 people in Changzhou.

Freudenberg: new thermal insulation allows for sustainable disposal
The degradation of conventional polyester, which is contained in 60% of all garments, takes 500 years on average. The new cellulose padding by the manufacturer of technical textiles Freudenberg Performance Materials Holding SE & Co. is completely biodegradable within 60 days. This innovation, called comfortemp Lyocell padding, was presented at the Ispo in Munich/Germany from 26-29 January 2020.
Freudenberg is thus responding to the increased demand for the sustainable disposal of garment. The padding is based on cellulosic lyocell fibers by the producer of cellulosic fibers, Lenzing AG, Lenzing/Austria. Lyocell is cellulose produced from natural raw materials in an environmentally friendly production process using eucalyptus wood from sustainable forests and has been awarded with the European Award for the Environment. The solvent used to obtain the fibers is almost completely reused in the production cycle. It allows for a thermal insulation providing warmth, while being both soft and highly breathable, as well as to absorb body moisture up to 45%. It is also water-repellent, dries quickly, is antistatic and conforms to the Oeko-Tex 100 standard.
Hohenstein: New analytical method records the release of microfibers in textiles
What quantities of microfibers and thus of microplastic are released from textiles? A new method for analyzing microfiber shedding from textiles has been developed by the Hohenstein Institute, Bönnigheim/Germany. It is the result of 4 years of research at Hohenstein Institute and published in the PhD thesis by Jasmin Haap.
Dynamic image analysis is used to determine not only the mass, but also the number, length, shape and diameter of the detached fibers. The sample is not destroyed, so that additional tests can be carried out for further analysis. With this level of detail, researchers and users in the field of textiles can now quantify in more detail which types of fiber and material constructions contribute most to microfiber release. The method is therefore leading to informed decisions in the development of more sustainable textiles and production processes.
Advansa: Sverige will be new shareholder
On January 29 the curator of the manufacturer of polyester fibers Advansa GmbH, Hamm/Germany, announced an agreement with the Investment Holding Sverige Netherlands B.V., Hoofddorp/Netherlands, to acquire all the assets of Advansa GmbH as well as the other relevant companies of the Advansa Group. Among them are, for example, Advansa Marketing GmbH, Hamm, as well as Bergers Technik und Maschinenbau GmbH, Hamm.
Sverige is affiliated with the major shareholders of the manufacturer of polyester PT Asia Pacific Fibers Tbk. (APF), Jakarta/Indonesia. APF manufactures and markets polyester chips, staple fibers, filament yarns and fleece fabrics along with captive PTA. Sverige expects that its investment in Advansa will lead to close cooperation between Advansa and APF, permitting each company to realize the synergies, having plants in both Europe and Asia and with the possibility to offer a wider portfolio of products to customers.
All the Advansa technology and trademarks will remain with the group, including the rights to former DuPont polyester technology and brands in Greater Europe.
Approximately 165 Advansa employees will continue with the Advansa Group, along with all relevant intellectual property, equipment, technology and brands. The closing of the transaction is in preparation and is expected in about one month after completion of usual conditions.
Andritz: new nonwovens production line started in Poland
A new production line nexline spunlace excelle of the international technology group Andritz AG, Graz/Austria, was successfully commissioned at the nonwovens manufacturer Novita, Zielona Góra/Poland. The line is used for the production of a wide range of spunlace fabrics from 30-100 g/m² and even down to 25 g/m² and enables Novita to enter the hygiene and medical market.
The production line consists of 2 TT cards, a hydroentanglement unit including the energy saving system nexecodry, water filtration and recycling systems and a double-drum through-air dryer. Only a few weeks after start-up, the line reached 250 m/min and is now running at a stable speed of 300 m/min.
I.S.T.: new high-tech fiber with ultra-high tensile strength
For the first time worldwide the technology group Industrial. Summit. Technology. Corp. (I.S.T), Otsu/Japan, presented the new high-tech polyimide fiber Imidetex to the sport market at the Ispo Munich 2020 from January 26-29, 2020 in Munich/Germany.
While Imidetex has an ultra-high tensile strength equivalent to the aramid fiber Kevlar, it is also characterized by additional features, bringing infinite opportunities to enhance sporting goods and the quality of athletes’ life alike.
A super-fiber made of polyimide resin, widely used in the outer space, Imidetex is based on a unique ultra-violet stable and high temperature resistant polymer, to grant very good features in equipment and parts. The fiber has very high tensile strength and modulus allowing products made of the fiber to stand heavy loads.
For example, a rope made of Imidetex is 80% lighter than steel ropes of comparable strength. The fiber also has low water absorption and very good UV resistance, which make it possible to play active roles in various fields including outdoor and sports scenes in harsh environments that other conventional para-aramid fibers could not fulfill.
