Abstract
Examines the tenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Abstract
The aim of the presented research is to apply the method of punch deformation for the simulation of textile systems behaviour in serve conditions and on the basis of it create original method and find new criteria for shape stability evaluation. The research was done with the help of three devices of punch loading originally created at Kaunas University of Technology (Lithuania), which were attached to the standard tensile testing machine. Creep tests were performed by a special device, clamping radius of which was R=56.5 mm. Creep process was controlled up to the stabilisation of shells height, i.e. after t=48 h. Tests were carried out in wet and dry states of the specimen. Two different types of textile systems (I+K and K+I) composed of two layers were investigated (where K – outer material; I – interlining).

Abstract
Purpose
The purpose of this paper is to optimise parameters of digital image analysis to investigate the deformation behaviour of woven sample and to detect the onset and variation of wrinkling that occurs due to bias‐tensioned fabric buckling.
Design/methodology/approach
Using models of predescribed shape, the relationship between the digitized gray scale intensities and wrinkles of the surface are analysed and conditions of specimen illumination and filtering procedures are chosen.
Findings
It is proposed to convert acquired images to binary to record the onset of buckling and to estimate critical buckling parameters of stretched woven samples. The threshold value is determined as mean value of approximated histogram of stretched specimen centre line. It is defined that profile curve and gray scale disperse presented by parameter CV can be used to obtain additional information and to compare behaviour of different samples during bias tension.
Research limitations/implications
Proposed image analysis technique allows detection of the onset of buckling wave formation and evaluation of surface waviness changes in woven samples different in colour and weave type tension. However, the behaviour of fabric samples with sharp multicoloured and complicated patterns cannot be assessed by gray scale imaging.
Originality/value
The proposed approach can be adjusted to investigate different wrinkling problems – buckling during simple shearing or picture frame test, seam puckering, draping.

Abstract
The goal of this research work was experimental investigation and evaluation of biaxial punch deformation processes of anisotropic textile materials. The investigation was aimed to solving the following problems: tofind a new criterion for textile behaviour evaluation in punch loading; to evaluate theeffect of material anisotropy for the geometry offormed shell; to determine the straindistribution in anisotropic shell. The experimental data of X‐ray diffraction analysis showed that friction at specimen/punch contact, which earlier was ignored, has a significant effect upon the parameters of the punching process.

Abstract
Looks at the eighth published year of the ITCRR and the research, from far and near, involved in this. Muses on the fact that, though all the usual processes are to the fore, the downside part of the industry is garment making which is the least developed side. Posits that the manufacture of clothing needs to become more technologically advanced as does retailing. Closes by emphasising support for the community in all its efforts.

Abstract
Purpose
The aim of presented investigation was to test developed testing device Griff tester, created for the objective evaluation of textile hand and to compare the obtained data with sensory evaluation results of textiles, subjected to different final treatments.
Design/methodology/approach
The effect of two finishing products, i.e. the crease‐resistant finishing Knittex® “K” and the softener macro silicone Ultratex® “Ul” upon 100 per cent cotton plain weave fabric was studied by two methods – objective evaluation and sensory analysis. Objective evaluation was done using Griff tester device where disc shaped specimen was extracted through a rounded hole of the stand. Sensory analysis was performed by the panel of 11 trained persons.
Findings
Investigations have shown that both treatments changed the hand of the fabric in the expected direction. Meantime, two experimental methods (objective and sensory approach) have shown their effectiveness to evaluate the textile touch, respectively.
Practical implications
The obtained results proved that criterion Q can be used for sensitive and vivid detection of differences between fabrics, affected by different final treatment operations. The effects of finishing products' concentrations were found to be in accordance with the manufacturer's technical specifications and with the finishing industrialist's expectations.
Originality/value
Investigation results obtained by Griff tester revealed the possibility of fabric hand evaluation on the basis of one relative criterion Q. These results can be linked with some attribute issued of the sensory analysis applied to the characterisation of the tactile feeling.
