In this paper we introduce and characterize a new type of connector between smart textile and electronic devices. The connector is based on a ball grid array structure which is pressed against conductive textile pads in a stretchable pocket. The connector keeps textile and electronics fabrication separate. It offers 56 connections on an area of 60 × 100mm2, which is about the size of a smart phone. The resistance of the connection is 1.4ω at DC, mostly constant up to 10 kHz and below 3ω up to 100 kHz. This resistance is low compared to measured sensor resistances for resistive pressure sensing or bio-impedance sensing. © Copyright 2015 ACM.

At the ITMA 2011 in Barcelona/Spain, there were outstanding innovations, but no surprises which the experts did not already know about, with one exception: the 200,000 rpm of the rotor spinning machine Autocoro 8 by Oer-likon Schlafhorst, Ubach-Palenberg/Germany. Further innovations at the fair prove that the strong competitive situation in spinning engineering is helping the sector to assert itself better in Asia. However, less visitors from Asia were noticed, and Asian exhibitors were also underrepresented. Despite extreme economic difficulties in the past, development efforts have not subsided. Reliable innovative machine concepts received distinct recognition through further suppliers. In 2007 it was still about building cost-efficient machines with a reduced range of functions. Now, recent developments have allowed the productivity of the machines to be increased considerably. The focus was also on energy consumption and use of resources.

As opposed to the weaving techniques with conventional leno weaving loom, there are underlying special kinematic conditions in the new leno weaving process which are worth considering in the development of new fabric constructions. Using the EasyLeno 2T technology of the Lindauer Dornier GmbH, Lindau as example, the basic interrelationships between the dynamic warp thread tractions and the fabric construction for more compact fabrics are discussed.
