Amann: closed recycling management thanks to new PA sewing thread
With the recycled sewing thread Lifecycle Polyamide, made from polyamide 6.0 (PA 6) continuous filaments, the manufacturer of sewing threads and embroidery threads Amann & Söhne GmbH & Co. KG, Bönnigheim/Germany, offers Cradle to Cradle threads.
Lifecycle Polyamide was developed in cooperation with the internationally active consulting institute EPEA GmbH - Part of Drees & Sommer, Hamburg/Germany. The raw material for Lifecycle Polyamide is obtained from recycled fishing nets and other textile waste. Amann does not use any silicones, since no materials that are harmful to health and/or the environment may be used during production. Only compostable dyes are used. Lifecycle Polyamide is therefore certified according to Cradle to Cradle and optimized for recycling as a raw material in the technical cycle. It allows for a consistently closed recycling management without any further waste.
Cradle to Cradle, stands for products that are either used as biological nutrients in biological cycles, or that are continuously kept in technical cycles as technical nutrients. It evaluates the 5 categories material health, material reuse, use of renewable energies, water management and social responsibility.
Freudenberg: nonwovens crimping material offers comfort at reduced costs
The producer of technical textiles Freudenberg Performance Materials Holding SE & Co. KG, Weinheim/Germany, is responding to the increased demands of the footwear market with an innovative crimping material made of nonwovens. The new fabric will be presented at the Lineapelle leather goods trade fair in Milan/Italy from February 19-21, 2020.
Freudenberg’s crimping material shows high irreversible deformability and dimensional stability with flexibility and soft material character. In contrast to knitted linings, the multi-directional stretching properties of the material allow uniform longitudinal and transverse stretching over the entire vamp area. A low weight-to-area ratio of the crimping material also leads to further weight reduction of the shoe.
For end users, the wearing comfort is increased, while producers reduce their costs in the production process. This is because the possibility of a direction-independent cutting leads to as much as 10% lower waste. Faster thermoplastic deformability in turn enables shorter production times. After more than 72 hours, the milled sheet still has a 100% accurate impression. At the same time, the high cut edge strength increases the creative possibilities in shoe design.

Water UK: soluble wet wipe awarded Fine to Flush accreditation
The world’s first 100% environmentally friendly soluble wet wipe that dissolves in seconds when immersed in water has been awarded the Fine to Flush accreditation by Water UK, London/UK. Fine to Flush is the new official standard identifying which wet wipes can be flushed down toilets safely. The new wet wipes from McCormack Innovation, Kirkcaldy/UK, are not only flushable, they are also biodegradable for landfill.
Wet wipes are the principal cause of 50-70% of blockages in UK sewers. There are around 300,000 sewer blockages each year, costing the country in excess of £100m annually. The majority of wet wipes contain various synthetic fibers, which makes their disposability problematic and time consuming. Some wet wipes could take as long as 100 years to biodegrade.
PyroTex: heat resistant fiber for home and outdoor textiles
The first product for end consumers by the fiber producer PyroTex Fibers GmbH, Hamburg/Germany, is a multifunctional blanket that is not only flame-resistant, but also serves as an accessory for living, automotive, outdoor and leisure. The high-tech fiber PyroTex is already used in areas that require fire resistance, for example in aircrafts, workwear or in filtration.
According to Robert Jarausch, managing director of PyroTex, the heat resistant fiber is well suited for the home textiles sector as it has soft, warming and antibacterial properties without the use of chemicals.
The new multifunctional blankets, for example, have been awarded the M1 certificate; the PyroTex fiber is certified in accordance with Standard 100 by Oeko-Tex.

Lenzing: 2nd pilot plant completed for Tencel Luxe filament yarn
The producer of cellulosic fibers, Lenzing AG, Lenzing/Austria, has completed the 2nd pilot production plant announced in May 2018 for its innovative lyocell filament yarn Tencel Luxe. Construction of the facility at the Lenzing site involving investments of €30 million could be concluded on schedule and within budget after 20 months of intensive work. The new pilot production line, which was put into operation in the middle of December 2019, gives Lenzing sufficient capacity for commercial programs and further application development.
The properties of the Tencel Luxe fine filament yarn can be compared to those of silk due to its airy feeling on the skin and the matte finish. At the same time, it also stands out because of its extensive strength and high level of environmental compatibility. It is very well suited for very fine fabrics and in blends with silk, cashmere and wool.
The pilot plant developed by Lenzing and the know-how acquired during the construction phase will comprise the basis for the company’s further expansion in the field of sustainable filament yarns. This will also comprise the starting point for the planned construction of a large commercial production plant at the Lenzing site.
Oerlikon Nonwoven: new meltblown and spunbond technology at the Filtxpo 2020
Experts of the Nonwoven business unit of the Manmade Fibers segment of Oerlikon Management AG, Pfäffikon/Switzerland, will be presenting solutions for filtration tasks to an international trade audience at the trade fair for filtration Filtxpo 2020 in Chicago, IL/USA, which takes place on February 26-28, 2020.
Meltblown technology is a method for producing fine, separating filter media made from manmade fibers. It is characterized by its constant melt pressure distribution and consistent dwell time across the entire width of the spinning beam. Furthermore, the novel guidance and distribution of the process air outside the coat-hanger distributor offered by the Oerlikon Nonwoven technology prevents so-called hotspots, which overall ensures homogeneous nonwovens properties and basis weights even in the case of delicate raw materials.
The filter efficiency can be increased by means of so-called electro-charging – where the nonwovens are electrostatically charged. Users can choose from a number of variation possibilities and set the appropriate charging method depending on the filter application, allowing the Oerlikon Nonwoven charging unit to also be used for the manufacture of EPA and HEPA class filter media.
Regarding spunbonds, the company is presenting its segmented spin packs, which guarantee even melt distribution and polymer dwell time. The new forming section ensures improved formation evenness across the entire width, even in the case of high spinning speeds, special polymers and polymer combinations. In addition to this, the newly-designed system also ensures that nonwovens only require minimal edge trimming at the end of the production process. The newly-developed mixed fiber technology enables the combining of various filament cross-sections and polymers, in order to set ideal filtering and pleating performances, for example.
