Dilo Group was at IDEA 2019 with the Most Recent Machine Concept

Dilo Group participated in IDEA 2019 exhibition held in Miami between 26-28 March. The most recent machine concepts from DiloGroup companies DiloTemafa, DiloSpinnbau and DiloMachines promoted with the emphasis on new equipment components which improve product quality, increase line capacity and furthermore enable new opportunities in nonwoven production.

DiloTemafa has introduced versions of the Baltromix bale opener and the card willow which are particularly suited to the processing of longer fibres at highest throughput. Longer cleaning intervals and shorter cleaning times also result from the design changes.

DiloSpinnbau has a new “Unifeed” card feeder (VRS-P) which combines the principle of volumetric charged feeding with the characteristics of a chute feeder but without the conventional overhead trunk which allows for lower ceiling height requirement. The fibre flock matt is condensed by a vacuum delivery apron to give better uniformity of mass distribution. The distribution over the working width is controlled by additional flaps. This feeder can be adapted for medium/fine to coarse and medium to long staple fibres.

The “VectorQuadroCard” incorporates a modular transfer group between breast and main section. The quick change facility of this roller group provides different carding options. The delivery system is also flexible to provide parallel laid, random or condensed web.

DiloMachines has a new horizontal crosslapper version “DLSC” which allows web infeed speeds up to 200 m/min depending on fibre specification. Such infeed speeds will prevent the lapper being the line bottleneck. The DLSC works in conjunction with the proven CV1A web regulation system for improved felt evenness and the potential for fibre savings. A further increase of the drive power within the three-apron-layering technology as well as the application of carbon fibre reinforced parts enables these major improvements.

Developments underway relating to the needling process include “Needle Module Technology” whereby needles are pre-mounted in multiple units of 22 for insertion into very high-density boards. It is reducing visible mark- ing patterns on the product´s surface significantly. Furthermore, it enables a simplified Needle insertion and shorter setup time.

In addition to wide needling lines for  the  economic   production of large volume products as in the geotextile industry, Dilo offers a “plug-and-play” compact line which is designed for the production of small amounts of high-quality felts, used e. g. in the medical sector and for specialty felts made from high-tech fibres.

The Dilo Compact Line includes fibre opening and blending, card feeding, carding and crosslapping, needling and winding. The working width of the compact carding machine is 1.1 m, the layering width is 2.2 m. Numerous innovations were realized in every single machine. These innovations also facilitate the modifications necessary for the needling of carbon fibre.

Dilo has introduced a new “HyperTex” technology which pro- duces multi-layer felts made from base web, reinforcing layer and upper web. By using the scrim fabric machine of Ontec Automation GmbH it is possible to integrate a grid of unconsolidated yarn or filaments between two webs. The scrim can be fed inline and is then needled together in the subsequent needle loom. A great advantage of this method is the very high production speed for the complete process. Scrim formation and subsequent nee- dling achieve speeds up to 40 m/min.

Thies is at Techtextil 2019 With Its Latest Range of Machines

Thies Textilmaschinen, 14-17 Mayıs tarihlerinde düzenlenecek olan Techtexil 2019 fuarında Salon 3’te F23 standında, teknik tekstillerin işlenmesinde kullanılan en yeni makinelerini tanıtacak.

The machines process a wide variety of yarns, fibres, nonwovens and fabrics suitable for various technical textile applications: for example aramide fibres which are used for security wear and top-end, bullet-proof automobiles.

iCone

The newly developed dyeing machine “iCone” treats yarns, fibres, flakes, cables, ropes and belts. The new technique enables dyeing in short fleet. Obtaining uniform dyes and the required fastness is self-evident. Due to the new energy-efficient (ee) functions the “iCone” is able to colour in a more cost effective and environmentally friendly way.

Another field of application is the discontinuous bleaching of cellulose fibres for medical purposes and/ or any other fibres such as polyester, acrylic and polyamide.

In the Thies product portfolio one can find the corresponding presses and dryers. Furthermore, the variety of “iCone” is reflected in the following areas of application: The treatment of threads, the dyeing and bleaching of yarns for the production of solar sails, tents, awnings and the finishing of hard-retardant yarns.

HT- Jigger

The Thies HT-Jigger is used for dyeing fabrics, nonwovens or space fabrics in open width form. The HT-Jigger offers stepless tension and material speed control with an economical dye trough. It has been designed to offer uniform dyeing in short liquor ratios. Suitable to process textiles at temperatures up to 1430C, the HT-Jigger is recommended for the treatment of crease sensitive, permeable and non-permeable fabrics; to offer optimum flexibility for finishing of all modern fibres.

iMaster H₂O

For applications where water consumption is an important con- sideration, together with other possible energy savings including steam, electricity plus chemicals and dyestuffs, the wellestablished iMaster H 0 dyeing machine is already proving successful with several automotive fabric producers. The notable process times of the iMaster H O dyeing machines facilitate higher production capacities.

The system features a transport winch inside the kier, allowing cotton, synthetic fibres and their blends, and including articles with a high elastane content, to be processed with significantly reduced elongation; resulting in fabrics with an improved stability whilst offering flexibil- ity in the processing of a wide range of products.

soft-TRD Slll

Designed for the universal dyeing of wovens, knits and nonwovens, this third generation of soft-TRD machines sets new standards in the efficient use of materials and resources.

The soft-TRD SIII is able to handle crease and surface sensitive articles at fabric speeds of up to 600 m/min. The free material flow and low intensive transport zone, guarantee optimum relaxation and uniform treatment of the entire rope.

The special design with its swimming material transport provides the finisher with increased flexibility in the processing of a wide range of fabrics and material weights.

Thies Multi Product Supply- System

Chemical and dyestuff feed systems complement the product range of the German Textile machinery manufacturer, Thies. The MPS-Systems supply dyeing and other finishing machines with chemicals, dyestuffs and textile auxiliaries. The individual design and the ideal synchronisation are noteworthy.

Heat Recovery System

To gain energy out of hot industrial waste water is the aim of Thies’ heat recovery systems. Special tubular heat exchanger allow high efficiencies and low payback periods. Various modern types can be connected to these systems.

Perlon® will Present PearlTech® a Monofilament with a Special Surface

Perlon® will showcase PearlTech®, its latest product brand at Techtextil in Frankfurt from 14th – 17th May.

PearlTech® is a monofilament which has special particles incorporated into it. The size and shape of the particles is irregular and the material is unrelated to the base polymer. The particles are added into the polymer melt and evenly distributed over the whole cross-section. These newly acquired properties remain in- tact throughout the lifetime of the monofilament. The particles incorporated into the polymer matrix protrude slightly from the monofilament surface, giving PearlTech® an interesting optical appearance and a structured surface finish.

PearlTech® provides improved stability against wear, reduces machine power consumption (along the lines of Per- lon® Enersave®) whilst reducing the build-up of dirt on  the  end  product. The particles have no negative effect on hydrolysis resistance and furthermore offer the possibility to avoid the use of fluoropolymers. For this reason, PearlTech® provides a viable alternative to Perlon® EasyKleen® monofilament. PearlTech® monofilaments are notably used in sieves for the paper industry. They can also be used in the field of Advanced Technical Textiles for example in filtration (in particular solid-liquid separation) and in conveyor belt fabric. Through its ability to be customized, PearlTech® opens up the market for a host of new possibilities.

Perlon® QualiFil® range includes monofilaments with special properties such as flame retardancy (FireRetard®), elasticity (ElasTer®), abrasion resistancy (DuraFil®), stain resistancy (EasyKleen®), energy efficiency (EnerSave®) and UV stability. To avoid the need for a separate coating process, Perlon® has developed HighGrip monofilaments with tribological properties. These PET based BiCo monofilaments have a specific surface with special adhesive properties and different softening points. Bayco® (monofilaments for agriculture), Atlas® (Monofilaments for nautical rope) and PerlonXline (monofilaments for angling) round off the QualiFil® brands.

Perlon Group understands the need for sustainability in the future. The company is currently developing and carrying out research in the bio-monofilament field.

New Composite Advances Lignin As A Renewable 3D Printing Material

Scientists at the Department of Energy’s Oak Ridge National Laboratory have created a recipe for a renewable 3D printing feedstock that could spur a profitable new use for an intractable biorefinery byproduct: lignin.

The discovery, detailed in Science Advances, expands ORNL’s achievements in lowering the cost of bioproducts by creating novel uses for lignin—the material left over from the processing of biomass. Lignin gives plants rigidity and also makes biomass resistant to being broken down into useful products.“Finding new uses for lignin can improve the economics of the entire biorefining process,” said ORNL project lead Amit Naskar. Researchers combined a melt-stable hardwood lignin with conventional plastic, a low-melting nylon, and carbon fiber to create a composite with just the right characteristics for extrusion and weld strength between layers during the printing process, as well as excellent mechanical properties.

Lignin chars easily; unlike workhorse composites like acrylonitrile-butadiene-styrene (ABS) that are made of petroleum-based thermoplastics, lignin can only be heated to a certain temperature for softening and extrusion from a 3D-printing nozzle. Prolonged exposure to heat dramatically increases its viscosity—it becomes too thick to be extruded easily.

But when researchers combined lignin with nylon, they found a surprising result: the composite’s room temperature stiffness increased while its melt viscosity decreased. The lignin-nylon material had tensile strength similar to nylon alone and lower viscosity, in fact, than conventional ABS or high impact polystyrene.

The scientists conducted neutron scattering at the High Flux Isotope Reactor and used advanced microscopy at the Center for Nanophase Materials Science—both DOE Office of Science User Facilities at ORNL—to explore the composite’s molecular structure. They found that the combination of lignin and nylon “appeared to have almost a lubrication or plasticizing effect on the composite,” noted Naskar. “Structural characteristics of lignin are critical to enhance 3D printability of the materials,” said ORNL’s Ngoc Nguyen who collaborated on the project. Scientists were also able to mix in a higher percentage of lignin—40 to 50 percent by weight—a new achievement in the quest for a lignin-based printing material. ORNL scientists then added 4 to 16 percent carbon fiber into the mix. The new composite heats up more easily, flows faster for speedier printing, and results in a stronger product.

‘Cool’ Textile Automatically Regulates Amount of Heat that Passes Through It

Made from specially engineered infrared-sensitive yarn, which responds to changes in the temperature and humidity of a person’s skin by dynamically collapsing or expanding the structure of its fibers, the newly-developed textile shows great potential in the development of clothing systems capable of autonomously adapting to demanding environments.

The human body absorbs and sheds much of its heat in the form of infrared radiation. Most textiles trap this energy, which keeps us warm in cold weather. However, the development of a material that is able to shed this energy, and thus passively cool the body, has remained a challenge. While other materials have achieved radiative cooling in various forms, through textiles that can reflect sunlight and also allow heat radiating from a person’s body to escape, none are responsive to environmental changes or possess the ability to regulate both heating and cooling. The base yarn for the new infrared-adaptive textile is created with fibers made of two different synthetic materials — one absorbs water and the other repels it. The strands are coated with carbon nanotubes, a special class of lightweight, carbon-based, conductive metal.Because materials in the fibers both resist and absorb water, the fibers warp when exposed to humidity such as that surrounding a sweating body.

That distortion brings the strands of yarn closer together, which does two things. First, it opens the pores in the textile. This has a small cooling effect because it allows heat to escape. Second, and most importantly, it modifies the electromagnetic coupling between the carbon nanotubes in the coating.

Professor YuHuang Wang, also from the University of Maryland said “It’s a very simplified way to think of it, but imagine bringing two antennae close together to regulate the kind of electromagnetic wave they pick up. When the fibers are brought closer together, the radiation they interact with changes. In clothing, that means the fabric interacts with the heat radiating from the human body.”

Depending on the tuning, the textile either blocks infrared radiation or allows it to pass through. The reaction is almost instant, so before people realize they’re getting hot, the garment could already be cooling them down. On the flip side, as a body cools down, the dynamic gating mechanism works in reverse to trap in heat.“The results of testing the material show that the textile was able to alter heat radiation by over 35% as it adjusted to the surrounding relative humidity,” the scientists said.

“The heat-adapting meta-fibers can be knit, dyed and washed similarly to other performance fabrics and are compatible with current commercial processes.”

Cut Resistant Clothing for the Glass and Metal Industry: CutPRO®

Cut resistant fabrics have been developed following thousands of injuries suffered by individuals in industry, homeland security, and extreme sports. Now, UK-based PPSS Group is urging product designers to think innovatively about the potential applications of its technical textile, Cut-Tex® PRO.

Since its inception, cut resistant fabric Cut-Tex® PRO has been effectively used in slash resistant clothing for law enforcement, security, and prisons and corrections personnel, as well as bite resistant clothing for healthcare professionals. Following extensive research and collaboration, the company launched its range of cut resistant clothing for the glass and metal industry: CutPRO®. CEO Robert Kaiser comments: “Since the beginning, we have been approached by individuals looking to use Cut-Tex® PRO for theft-proof beach bags, travel cases, storage protection, and even animal welfare. Whilst we cannot guarantee effective- ness in all applications without thorough testing, we have been delighted to work with so many innovative thinkers eager to use Cut-Tex® PRO as a solution for their  product.” The key benefits of fabric are its versatility and all-round performance. Not only does Cut-Tex® PRO offer EN388:2016 Level E cut resistance (ANSI Level 5), unlike alternatives, its protective properties are enhanced by the highest levels of tear and puncture resistance, decreasing the risk of sharp objects penetrating the fabric. It is also washable, lightweight and kind to skin, offering unlimited possibilities for developing new or existing products.

At pH 6.6, Cut-Tex®PRO has a pH value similar to that of water (usually between 6.5 and 8.5). This makes it an extremely low risk skin irritation fabric. Used in clothing for homeland security, workers in manufacturing, and healthcare professionals, it will maintain the skin’s natural balance whilst providing outstanding protection from cuts, slashes, and even human bites.

Robert Kaiser said that; “We are keen to partner with anyone who shares our excitement for the future of cut resistant fabric, and hope that new and innovative applications will help us to advance the performance and capabilities of Cut-Tex® PRO over the coming years.”
