New Synthetic Textile Chains from Dyneema®

~ Uttu-Textiles ~ Leave a comment

Dyneema® is ultra high molecular weight polyethylene fibres made by DSM Dyneema, which is considered the world strongest fibre and as reliable as steel but with 15% the weight.

Dyneema® has produced a new synthetic textile chains as a replacement for the normal metal chains. The new chains are made from layers of narrow woven fabrics from Dyneema® fibres reducing the weight up to 85% from the comparable steel link chains and significantly stronger at the same diameter. The lighter weight chains allow better handle and increase in productivity.

Properties

The Dyneema® chains are also considered safer as they don’t recoil or whip back the way steal chains do. This is one of many positive properties of using textiles alternative materials. Other properties include quiet, causing less damage to the cargo, nonconductive, greener, reduce mechanical damage to equipments.

As the fibres specific weight is less than 1.0 g/cm3, the chains will float on the water. It has 4% elongation, which means it can be used for precise tasks.

The option of using different fibre versions allows different strengths for different applications.

Applications

This chains were developed for the heavy industry such as, material handling, transportation and logistics, mining, logging.

The light weight and high strength make these chains desirable for many applications. Image recourses

Anti-Cancer Wearables

~ Uttu-Textiles ~ Leave a comment

Wearable technology/electronics or “wearables”, as they might be called sometimes, are becoming more trendy. Many designers have used them to create all types of functional fashion. Many other researchers worked on the application of these wearables in the medical field for personal health management systems, such as; heart monitoring system, which are now widely available for athletics in many forms including belts, vests, bra … etc.

Recently, Novocure presented a cancer treatment wearable system called Optune, Figure 1.

Optune creates an alternating wave-like electric fields called Tumor Treating Fields, TTFields. These field travel across the upper part of the brain in different directions to help slow or stop recurrent glioblastoma cancer cells from dividing and do not harm healthy cells.

Data showed that the use of this method with other treatment increased the patient survival years. The  transducer arrays are placed directly on the scalp to target the tumor and it is based on each patient’s MRI results to maximize the therapy’s effect on the tumor, Figure 2.

This month, the WIPO has published a patent called the Nanoparticle Phoresis for Google. In this patent a wearable device will detect functionalized nano particles in the blood that able to identify and get stuck to harmful cells. The nano particles then will destroy the cells by the use of the magnetic field generated by  the wearable device.

Textiles already plays a major role in the medical field and with the technological advances in electronics and other fields, textiles as wearables will be used in more in this vital application.
