Top ten textile technologies of today

Now-a-days technological advances made in the textile sector indicate the dawn of a new era here are some technologies to watch out for this issue of Bangladesh Textile Today (BTT). I, Md. Shayekh Munir, Technical Team Member at BTT would be editing this division regularly for our readers. All are requested to send such developments to be at munir@aminjahan.com.

1. INOTEK: Adaptive moisture management fibre technology

MMT Textiles Ltd, a London based innovative new textile technology company, announced that it had invented and patented a method of constructing bio-responsive fibres and yarns so that they react to humidity levels in a micro-climate. Inotek’s adaptive technology is inspired by the botanical structure of pine cones, which open and close in response to moisture levels. Conventional fibres swell as they absorb moisture. This causes the yarn to swell, reducing the permeability of the textile structure.

The porosity of knitted, woven or non-woven fabrics incorporating the bio-responsive fibres, increases high levels of humidity or wetness in the micro-climate, facilitating the release of moisture, or decreases in low level humidity or dry conditions, improving insulation. The new technology will enable manufacturers of textile items like sports clothing, base layers, underwear, socks and bedding fabrics to bring new products to market that improve the comfort of their customers by keeping them dry for longer and getting them dry more quickly in extreme conditions.

2. Fibre squeeze roll with full chemical resistance technology

Richard Hough Ltd. (RHL), the UK based, calendar roller manufacturer, invented the first fibre-based squeezing system to offer full resistance to harsh chemicals.A revolutionary new version of the famed Roberto roll is said to be the first fibre-based squeezing system to offer full resistance to harsh chemicals. Recently announced of the RoberteX’s special chemical resistance properties extends the range of dewatering options offered.  Previously, the RHL Resilio rubber-squeezing roller was the only option for high water expression with total chemical resistance, but its use is limited to woven and knitted fabrics.

Different forms of yarns can be dyed such as cheese, cones, hanks, loose fibre, etc. The capacity range is from 28 kg to 9129 kg. The outstanding performances of these features save total production cost by 30%,
ALLWIN dyeing machines shorten the total processing time for cotton yarn down to 276 minutes, saving electrical and water consumption respectively by over 40% and chemical cost by 19% compared with conventional machines.

5. Bio-Fiber Technology: TENCEL®Biosoft

Lenzing group from Austria introduces TENCEL®Biosoft, the first hydrophobic and home-compostable fiber leading to unique benefits for wipes and hygiene applications. TENCEL®Biosoft can be used in a variety of blends which tailor the absorbency and cleaning performance to suit a number of different functions from full oil absorbency through to specific lotion management.

In topsheets of hygiene products, excellent liquid strike through times and wet back properties ensure a comfortable dry feeling to the skin. Most important thing is that TENCEL®Biosoft is biodegradable.

6. New Carbon Nanotube fiber

New carbon nanotube fiber, cylindrical structure of carbon allotropes, acts like textile thread, conducts electricity and heat like a metal wire with unmatched combination of strength, conductivity, and flexibility. Developed by scientists from Rice University, the Dutch firm Teijin Aramid, the U.S. Air Force, and Israel’s Technion Institute. It looks like black cotton thread but behaves like both metal wires and strong carbon fibers. The specific electrical conductivity of the new fibers is on par with copper, gold and aluminum wires, but the new material has advantages over metal wires. For example, one application where high strength and electrical conductivity could prove useful would be in data and low-power applications.

New CNT fibers are as flexible and tough as a textile thread and hopefully this combination of properties will lead to new products with unique capabilities for the aerospace, automotive, medical and smart-clothing markets.

7. C6 based technology- Novatect LX3

Allinova, specialty Chemicals Company based in Nederlands, launched fluorocarbon emulsion, Novatect LX3 that combines high effective oil- and water repellency properties together with self-cleaning properties. One other main advantage of the Novatect LX3 is that it does not need a high temperature-curing step to active the final properties. Only drying at room temperature will do. Novatect LX3 is also very well suited for industrial applications wherein textiles (f.e. cotton, polyester, polyamide) will be cured up to 180°C.

Because this grade does not need the high temperature step to get the optimal performance. The final properties are quite homogeneously. Novatect LX3 is PFOA and PFOS free.

8. Technology in Denim: JUKI’s newly developed  AP-876/Automatic Pocket Setter

The hip pocket of jeans is a highly visible element of the products. The machine is able to fold a subsequent pocket and place it on a garment body while engaging in the sewing of the current pocket. This enables to carry out a series of pocket setting processes at 9.9 seconds / pocket. The machine achieves high productivity with one unit by performing the pocket setting, folding and sewing simultaneously.
