Teijin: fishing net made with UHMWPE film
A high-performance knotless fishing net made with an ultra-high molecular weight polyethylene (UHMWPE) film has been developed by the producer of advanced fibers and composites, Teijin Ltd., Tokyo/Japan, together with Kinoshita Fishing Net Mfg. Co., Ltd., Aichi/Japan.
MX-4 combines Teijin's advanced Endumax film and Kinoshita’s manufacturing technology implemented with net-knitting machines for knotless netting, made by crossing threads with each other for extra strength and abrasion resistance. Endumax is a 60μm-thick film offering high strength, high modulus and resistance to impact, abrasion, chemicals and sunlight. Kinoshita proprietary technology enables Endumax that has been cut to just mm in width to be knitted into highly functional MX-4 fishing net.
The net is especially suitable for purse-seine nets for skipjack, tuna, horse mackerel and mackerel, which are used in harsh environments where durability and fast drainage are crucial. MX-4 does not shrink easily and is resistant to breakage due to abrasion even after hundreds of castings, so it can be used safely for long periods. It also improves work efficiency and cost efficiency by reducing needs for net reconditioning and tailoring. Furthermore, it reduces the frequency of net disposal and is more marine friendly. When MX-4 is pulled up from the sea, it immediately sheds water and becomes lighter, making it easier to work. It also stays clean.
Stoll: Opening of the 2nd construction section
The merger between the textile machinery manufacturer Karl Mayer Textilmaschinenfabrik GmbH, Obertshausen/Germany, and the manufacturer of flat knitting machines H. Stoll AG & Co. KG, Reutlingen/Germany, was completed on July 1, 2020.
Stoll will be moving with its premises from the site at Stollweg in Reutlingen/Germany, to the Reutlingen-Betzingen industrial estate, where it will continue its activities under the new owner, as planned. Already in 2004, Stoll relocated its production to the location in the Mark West Industrial area in Reutlingen. Over the course of 2 project stages, a development center will first be built, and later a customer center will follow, in order to accommodate the other business units.
The official start of the construction for the development center was on July 26, 2019. The office building for approx. 70 employees is expected to be completed by autumn 2020.
July 29, 2020 saw the beginning of the 2nd project stage, with the aim to erect the customer center by 2021.

Teijin Frontier: next-generation heat insulating structure
A new heat insulating structure which combines sweat absorption and quick drying for innerwear and heat insulation for brushed-finish intermediate wear, or middler, worn between the inner and outer layers to retain heat has been introduced by the fiber-product converting company Teijin Frontier Co., Ltd., Tokyo/Japan. Applications of the new structure will include outdoor, sports, casual and uniform applications, as it offers a new type of bulky plush structure that does not brush. It is a double raschel knitted fabric cut in half with high precision. Its middle nodes are made with Octa, Teijin Frontier’s highly modified hollow-core fiber with 8 projecting fins aligned in a radial pattern. It also uses a distinct dyeing technology to maximize Octa’s crimping function and stabilize its high-quality plush structure. Very good comfort is enhanced with heat insulation (lightweight bulkiness and warmth) and yarn tips on the skin side that evenly absorb sweat and dry quickly.
Epson: Robustelli and For.Tex to merge
Seiko Epson Corp., Tokyo/Japan, has announced that group companies Fratelli Robustelli Srl, Villa Guardia/Italy, and For.Tex Srl, Fino Mornasco/Italy, will merge. The 2 companies are core Epson subsidiaries in the direct-to-fabric (DTF) textile printing sector. Robustelli develops and manufactures textile printers while For.Tex engages primarily in textile ink sales and support. Epson sees textile printing as one of the most promising growth areas for its printing solutions business. Growth will be fueled by a shift from traditional plate-based analog printing to digital printing solutions. Epson sees substantial opportunity to leverage its inkjet technology to expand its business and is thus strengthening its textile printing product lineup and operations. The merger is scheduled for completion by the end of 2020.
Fraunhofer IAP: efficient way of recycling cotton clothes
The technical hurdles to recycling clothing made of cotton have been too high in the past, but now a team of researchers at the Fraunhofer Institute for Applied Polymer Research IAP, Potsdam-Golm/Germany, together with re:newcell, Stockholm/Sweden, have cleared that obstacle. They are the first to produce a viscose filament yarn made of recycled cotton and have found a way to turn cotton clothes into new high-quality garments rather than lowly cleaning rags. Old clothes often end up as inferior products such as cleaning cloths rather than new garments. This is because they are often made of blends rather than a single type of fabric. To date, it has been impossible to separate these intertwined fibers. Researchers were able to extract the foreign fibers from the pulp by setting the right parameters for both the dissolving and spinning processes, for example, with effective filtration stages. This yielded a filament yarn, a continuous strand of fiber several km long consisting of 100% cellulose, the quality of which is comparable to that of wood-based regenerated cellulosic fiber. Compatible with the standard industrial process for making viscose rayon, the new fibers spun from this cotton pulp are suitable for mass manufacturing. The pulp is first activated with lye and then chemically derivatized. This yields a very pure alkaline viscose solution. Spinnerets riddled with several thousand 55 μm diameter holes then spin this solution in an acidic bath. The thousands of liquid jets emerging from the polymeric solution enable the derivatized cellulose to regenerate and continuously precipitate in the spinning bath to form a filament. The next step is to steadily reverse the chemical derivatization, and then wash and dry the filament for it to be wound onto a spool. Made of pure cellulose, this filament is eco-friendly. Rather than adding to the mountains of microplastics that pollute the oceans, it readily decomposes. This is a huge advantage over petroleum-based polyester fibers, which still predominate on the global market with a share of some 60%.
Oerlikon: Manmade Fibers Segment on track despite pandemic
The Manmade Fibers Segment of Oerlikon Management AG, Pfäffikon/Switzerland, delivered a resilient performance despite the corona virus pandemic, driven by the recovery of the filament equipment business in China and a diversified portfolio in products such as nonwovens, staple fibers, polycondensation and smart factory solutions.
In the 2nd quarter (Q2) of 2020, a significant increase in order intake was recorded, attributed to a quick recovery in demand in China and the rest of Asia and the increasing demand for the nonwoven meltblown systems used in face mask production. For the half-year H1/2020, the man-made fibers business booked more than CHF 500 million in order intake and is on track to fulfill its delivery schedules for 2020.
Sales declined by 22.8% in Q2/2020, mainly due to the extraordinarily high sales volume in Q2/2019. At constant exchange rates, sales declined by 17.7% to CHF 264 million. Sales in China were stable in Q2/2020 year-over-year, affirming the recovery in China from the shutdowns in Q1/2020. EBIT was CHF 30 million or 12.1% of sales (Q2/2019: CHF 51 million; 15.7%).
The nonwovens market is anticipated to continue developing positively, as many countries strive to become more strategically autonomous for items deemed critical.

Producers already operating an Andritz D-Tech surgical mask line can upgrade it to produce respiratory masks with a special kit.
Lenzing: new guidance for FY 2020 as Covid-19 impacts sales
As a result of the global Covid-19 crisis, the producer of cellulosic fibers, Lenzing AG, Lenzing/Austria, suspended its guidance for 2020. Whilst it remains difficult to give a precise outlook for 2020, Lenzing assumes from today’s perspective that the revenue generation and operating performance of the remaining 2 quarters will exceed those of the 2nd quarter (Q2).
In the first half (H1) of 2020, the company faced a historically difficult market environment with increased pressure on prices and volumes resulting from the corona crisis. Sales declined by 25.6% from €1.09 billion to €810.2 million in the H1/2020. In addition to price effects, the company also felt the decline in demand for textile fibers in all regions. The slightly higher demand for fibers in the medical and hygiene segments could not offset the losses.
EBITDA fell by 46.6% to €96.7 million in H1/2020. The EBITDA margin decreased from 16.6% to 11.9%. Net profit for the period amounted to €1.5 million (H1/2019: €78.8 million).
The 76th Annual General Meeting of Lenzing AG resolved on June 18, 2020, not to distribute a dividend for the 2019 financial year.
