Resumen:
Una universidad alemana ofrece un nuevo sistema para distinguir tejidos falsificados que permite analizar las fibras de forma no destructiva. Este sistema distingue entre cachemir o pashmina y los tejidos etiquetados con estas fibras pero que en realidad contienen poliéster y otras fibras sintéticas. El patrón de difracción característico de la fibra, grabado con una cámara USB, permite identificar el espesor, estructura superficial, grado de transparencia y estructura interna de la fibra. Se trata de un sistema fácil de usar y portátil. La universidad busca licenciatarios industriales con el fin de fabricar la solución.

Tittle:
Identification of high-grade textile counterfeits
Summary:
A German university offers a new tracker for fake textiles that enables non-destructive fiber analysis. It distinguishes between genuine cashmere or pashmina and those fibers that are labeled such but actually made from polyester or other synthetic fibers. The tracker is easy to use and portable. Industrial licensees with an interest in manufacturing the solution are sought.
Description:
High-grade textiles (e.g. cashmere, pashmina and other natural fibers) are nowadays often counterfeited. Shawls labeled as "100% Pashmina" are sometimes made out of almost 100% polyester or other synthetic fibers. For this reason, a tool to proof the fabric composition declared on the label is very desirable.

Investigation tools for textiles known from prior art are either based on a microscopic optical evaluation or on chemical analysis. These two methods imply the use of expensive equipment or a destructive analysis of a textile sample, respectively. Both are not affordable in the framework of routine product qualification procedures. A fast, easy-to-implement, low priced and non-destructive method to analyze the presence of a particular fiber, especially cashmere fibers, in textile items is not offered by the actual state of the art.

A German university has now developed a reliable method to determine the type and the nature of a fiber. The characteristic diffraction pattern of the fiber, recorded with a USB camera, enables the determination of the thickness, the surface structure as well as the grade of transparency and eventually the internal structure of the fiber. On the base of this information a reliable identification of the fiber material is provided.

An example of the analysis result is shown in the illustration. The image resulting from the measurement of a cashmere fiber (figure c) is characterized by thin long bright lines over and under the diffraction plane and it is clearly distinguishable from those of the other synthetic or natural fibers.

The method is easy to implement and does not require the use of an expensive and complex equipment. The setup to measure includes a laser light source, a device to mount the fiber, a camera sensor to record the diffraction pattern and a processing unit (e.g. a laptop). The machine is designed to fit in a suitcase in order to be available for measurements on site performed by customs authorities or quality inspectors. The equipment could be further developed and customized in the framework of a licensing cooperation with an interested manufacturer.
Advantages and Innovations:
· Conventional methods do not allow for inexpensive and at the same time non-destructive analysis
· Portable device allows fiber analysis anywhere
· Easy to implement ((e.g. by customs authorities)
· Automatic material identification
· Reliable and exact data processing
Stage of Development:
Available for demonstration
