Measuring Fabric handle to define luxury: an overview of handle specification in next-to-skin knitted Fabrics from Merino wool
Animal Production Science, 2010Co-Authors: T. J. Mahar, H. WangAbstract:An examination is presented of the relevance of luxury to the wool textile and garment supply chain. This examination leads to a review of the concept and importance of Fabric handle as a means of defining important aspects of Fabric quality. Examples are given for woven Fabrics of the general relationships between subjectively assessed Fabric handle attributes such as Fabric Softness and smoothness and measured low stress, generally high deformation, Fabric properties such as Fabric bending rigidity and extensibility. A brief overview is presented of the development of a system for predicting a set of subjectively assessed handle attributes for next-to-skin knitted Fabrics from measurable Fabric properties. Seven handle attributes selected by experienced assessors as being important for defining tactile sensations associated with next-to-skin knitted Fabrics were: Fabric smoothness, hairiness, Softness, tightness, dryness, warmth and weight. Subjective assessments on a 1–10 scale of these seven attributes, plus an assessment of overall handle, were conducted by 12 experienced assessors on 74 next-to-skin knitted Fabrics. The precision of the mean assessment of the 12 assessors ranged between 0.8 and 1.1, indicating that there was sufficient consensus on key Fabric handle assessments to justify development of a method for predicting them from measurements of the physical properties of Fabrics. All Fabrics were tested using the PhabrOmeter Fabric evaluation system, which records the force exerted during insertion of a Fabric into and through an orifice. Geometric parameters were derived to describe the PhabrOmeter force-displacement curve results, and statistical models were developed to predict the average handle assessments of the 12 assessors. The precision of the models in predicting the handle intensities of eight Fabric attributes on an independent validation set of 22 Fabrics was significantly better than the precision of an individual assessor (confidence limits = 1.4–2.6 and 2.5–3.8, for predicted and assessed ratings, respectively). A case is made that this technology has the potential to assist in the growth of new markets for Merino wool products.

transglutaminase mediated grafting of silk proteins onto wool Fabrics leading to improved physical and mechanical properties
Enzyme and Microbial Technology, 2007Co-Authors: Joao Cortez, Anna Anghieri, Philip L R Bonner, Martin Griffin, Giuliano FreddiAbstract:Transglutaminases have the ability to incorporate primary amines and to graft peptides (containing glutamine or lysine residues) into proteins. These properties enable transglutaminases to be used in the grafting of a range of compounds including peptides and/or proteins onto wool fibres, altering their functionality. In this paper we investigated the transglutaminase mediated grafting of silk proteins into wool and its effect on wool properties. A commercial hydrolysed silk preparation was compared with silk sericin. The silk sericin protein was labelled with a fluorescent probe which was used to demonstrate the efficiency of the TGase grafting of such proteins into wool fibres. The TGase mediated grafting of these proteins led to a significant effect on the properties of wool yarn and Fabric, resulting in increased bursting strength, as well as reduced levels of felting shrinkage and improved Fabric Softness. Also observed was an accumulation of deposits on the surface of the treated wool fibres when monitored by SEM and alterations in the thermal behaviour of the modified fibres, in particular for mTGase/sericin treated fibres which, with the confocal studies, corroborate the physical changes observed on the treated wool Fabric.

cross modal interactions between olfaction and touch
Chemical Senses, 2006Co-Authors: Luisa M Dematte, Daniel Sanabria, Rachel Sugarma, Charles SpenceAbstract:We report two experiments designed to investigate the nature of any cross-modal interactions between olfactory and tactile information processing. In Experiment 1, we assessed the influence of olfactory cues on the tactile perception of Fabric Softness using computer-controlled stimulus presentation. The results showed that participants rated Fabric swatches as feeling significantly softer when presented with a lemon odor than when presented with an animal-like odor, demonstrating that olfactory cues can modulate tactile perception. In Experiment 2, we assessed whether this modulatory effect varied as a function of the particular odors being used and/or of the spatial coincidence between the olfactory and tactile stimuli. The results replicated those reported in Experiment 1 thus further supporting the claim that people's rating of tactile stimuli can be modulated by the presence of an odor. Taken together, the results of the two experiments reported here support the existence of a cross-modal interaction between olfaction and touch.

Super Water Repellent Fabrics Produced by Silica Nanoparticle-containing Coating
Research Journal of Textile and Apparel, 2010Co-Authors: Hongxia Wang, Jie Ding, Tong Lin, Xungai WangAbstract:In this paper, we report on superhydrophobic Fabrics (polyester, wool and cotton) produced by a wet-chemical coating technique. The coating solutions were synthesized by the co-hydrolysis of two silane precursors, tetraethyl orthosilicate (TEOS) and an alkylsilane, in an alkaline condition. Without any purification, the as-hydrolyzed solutions were directly used to treat Fabrics, and the treated Fabrics had water contact angles (CA) as high as 170° and sliding angles (SA) as low as 5°. Three alkylsilanes have been used for the synthesis of the coating solutions, and all contain three hydrolysable alkoxyl groups and one non-hydrolysable alkyl, but with different chain lengths (C1, C8 and C16). It was found that the CA value increased with an increase in the alkyl chain length, while the SA showed a reverse trend. When the functional group had a C16 alkyl, the treated Fabric surfaces were highly superhydrophobic, with the CA not being affected much by the Fabric type, while theSA values were slightly affected by the original wettability of the Fabric substrates. The superhydrophobic feature was attributed to a highly rough surface formed by the particulate coating. Aside from the superhydrophobicity, the influence of the coating on the Fabric Softness was also examined.

A correlation study of subjective sensorial evaluation and objective Softness measurement of wool Fabrics
2010Co-Authors: Ana Cristina Broega, Lijing Wang, M. Elisabete Cabco-silva, Xungai WangAbstract:Comfort is one of the most important aspects of clothing, especially for next-to-skin garments such as shirts and trousers for summer. Sensorial comfort has a strong relationship with both the mechanical and surface properties of apparel Fabric. A comfortable textile material should have properties of Softness, smooth surface or texture, be pleasant to touch and very flexible. When assessing Fabric handle subjectively, the assessor usually strokes the Fabric surface with one or several fingers and squash the Fabric gently in hand. Thus, the perception of such handle includes complex parameters of compression, tactile sensation and textural effect. In this work, we attempted to use a simple technique of objectively evaluating Fabric Softness related properties, by measuring the force required to pull a Fabric strip through a series of parallel pins (the pulling force). We also subjectively rated the Fabric handle. The correlation analysis showed very good agreement between the Fabric pulling force and subjective hand rating.

An experimental study on Fabric Softness evaluation
International Journal of Clothing Science and Technology, 2006Co-Authors: Peihua Zhang, Xin Liu, Lijing Wang, Xungai WangAbstract:Purpose – To examine a simple testing method of measuring the force to pull a Fabric through a series of parallel pins to determine the Fabric Softness property. Design/methodology/approach – A testing system was setup for Fabric pulling force measurements and the testing parameters were experimentally determined. The specific pulling forces were compared with the Fabric assurance by simple testing (FAST) parameters and subjective Softness ranking. Their correlations were also statistically analyzed. Findings – The Fabric pulling force reflects the physical and surface properties of the Fabrics measured by the FAST instrument and its ability to rank Fabric Softness appears to be close to the human hand response on Fabric Softness. The pulling force method can also distinguish the difference of Fabrics knitted with different wool fiber contents. Research limitations/implications – Only 21 woven and three knitted Fabrics were used for this investigation. More Fabrics with different structures and finishes may be evaluated before the testing method can be put in practice. Practical implications – The testing method could be used for objective assessment of Fabric Softness. Originality/value – The testing method reported in this paper is a new concept in Fabric Softness measurement. It can provide objective specifications for Fabric Softness, thus should be valuable to Fabric community.

Influence of Sensory Modes on Fabric Softness Evaluation
Journal of Donghua University, 2012Co-Authors: Hu Ji-yongaAbstract:Previous studies considered neither the influence of sensory modes(exploratory manners and sensory modality) on Fabric Softness evaluation,nor the variance between different subjects in statistic analysis.As a result,their evaluation results were not comparable.By bringing consideration about both different exploratory manners and different sensory modalities(haptic,visual,visuo-haptic) into subjective assessment,the influence of sensory modes on Fabric Softness evaluation is demonstrated.The subjective evaluation reflects that the Softness evaluation is not influenced by the sensory mode significantly in general,but for thick and compressible Fabrics the soft evaluation is influenced by the exploratory manners significantly.Furthermore,there is a significant difference between visual and haptic(or visuo-haptic) modality for thin Fabric with high bending rigidity.In addition,for any Fabric sample,Softness evaluation values of all subjective evaluators obey a normal distribution.These conclusions help to standardize Softness evaluation procedures.

Psychophysical Characteristics of Fabric Softness Evaluation for Different Sensory Modalities
Journal of Donghua University, 2012Co-Authors: Hu Ji-yongaAbstract:Compared with the reference Fabric, the Softness of Fabric samples was estimated under tactile and visuo-tactile modality, respectively. For each modality, two different touching manners were used, namely laying press and holding bend. The correct proportion of Softness evaluation for each manner and each modality was analyzed with respect to the most correlated physical property of the samples. The proportion and the physical property were fit to a logistic psychometric function, by which the discrimination threshold for each manner and each modality was calculated. The results showed that the psychometric curve for sensory evaluation on Fabric Softness fitted the logistic function well under different modality. In addition, the evaluation manner with the most discriminability was the holding bend manner in the visuo-tactile modality.
