Abstract

Purpose

The purpose of this paper is to compare real fabric drape images and virtual fabric drape images created by a commercial software. To achieve an in-depth comparison, actual and virtual drape shape properties were considered under three categories: drape area, number of nodes and shape of folds. The results of this research are expected to be useful to improve the reality and accuracy of fabric and garment.

Design/methodology/approach

Five different fabrics were selected for this study. Fabrics’ mechanical properties were tested by fabric assurance for simple testing method, while drape properties were measured by a Cusick drape meter. A commercial garment simulation was used to generate virtual fabric drapes. Real fabric drape images and virtual fabric drape images were analyzed by an image analysis software and results were used to calculate drape properties. Regression analysis was performed to compare real fabric drape and virtual fabric drape properties.

Findings

Differences between real fabric drape and virtual fabric drape were stated clearly. Simulation software was found to be insufficient to reflect drape area. However, simulations were quite successful corresponding to the number of nodes. Only one simulation had +2 nodes than its actual counterpart. This study showed that area and node shape representations of simulation software should be improved while node numbers are sufficiently represented.

Research limitations/implications

There are alternative 3D garment simulation software available to the fashion business. All these companies are working on to improve their simulation reality and accuracy. Some of them are also offering various equipment to measure the fabric properties. In this study, Optitex 3D Suite was selected as the simulation software due to several reasons as explained in this paper. However, other simulation programs might also be employed to perform virtual fabric drapes. Furthermore, in this study, the drape images of five woven fabrics were compared. The fabric selection was done according to a pre-test and consequently similar fabrics were determined to be the subject of the study. However, the more the number of the fabrics, the better the comparison and eventually the better the assessment of simulation success. Therefore, it is prospected to test more fabrics with versatile fabric properties for further studies.

Originality/value

Drape shape was observed from three perspectives: drape area, node numbers, and node shapes. Dealing the problem from these perspectives provided an in-depth comparison of real and virtual drapes. In this study, standard deviation of peak angles was used to explain node distribution that is new to the literature to the authors’ knowledge.

Abstract

Purpose

The purpose of this paper is to analyse some mechanical properties and parameters of drapability using different methods from two different points of research area: knowledge bases and numerical modelling using the finite element method.

Design/methodology/approach

The approach consists of analysing some mechanical properties and parameters of drapability using different methods from two different points of research area: knowledge bases and numerical modelling using the finite element method. The knowledge bases, named FP_B‐1 and FPO_B‐2, were used to analyse the bending rigidity of fused panels. The numerical model of fused panel NMFP is used to analyse parameters of drapability.

Findings

Based on the analyses of bending rigidity and draping of fused panels the conclusions indicate the significance of interaction between mechanical properties and parameters of drapability of the fused panel to garment appearance. Furthermore, the methods used present a computer approach to the study of the fused panel properties important for the computer‐based engineering and the presentation of real behaviour of all aspects of clothes.

Practical implications

This numerical model of a fused panel enables a 3D observation of this aspect of clothes' which is a behaviour, very important contribution to the computer planning of the behaviour of produced clothes.

Originality/value

A better understanding of how to construct fused panels in clothing.

Abstract

The mechanical and physical properties of fusible interlinings and fabrics depend on their constructional parameters, but fused panel properties depend on all of them. A new approach is presented for analysing the dependence of the constructional parameters of fabrics on the properties of fused panels. This study was carried out on the basis of a knowledge base for predicting the formability of fused panels made from wool fabrics suitable for upper clothes. This knowledge base was constructed using program package RETIS for machine learning from examples. This knowledge was presented in the form of regression trees. Using regression trees it is possible to predict the properties of a fused panel as well as to analyse the influence of parameters on the properties of a fused panel. Furthermore the results of analysis gained by regression trees were compared and confirmed using experimental measurements.

Abstract

The paper presents the objective evaluation and prediction of properties of a fused panel. A system for automatic knowledge acquisition from a given set of examples presents an alternative way to build a knowledge base to determine the quality of a fused panel. On the basis of analyses of influential factors of fused panel quality the learning and testing set of examples to predict the bonding strength of fused panel has been formed.

Abstract

Purpose

Enzyme treatment technologies are frequently applied in textile processing for the modification of fabric handle appearance and other surface characteristics in regard to cotton and cotton blended fabrics. The purpose of this paper is to understand the impact of enzyme treatments on fabric preparation, dyeing, and finishing processes of woven fabrics. In particular, certain mechanical and surface properties of 100 percent cotton interlock knitted fabrics after treatment with a cellulase enzyme.

Design/methodology/approach

Interlock knitted fabrics were used for this research. These cotton fabrics were treated with experimental Trichoderma reesei cellulases containing different cellulase profiles and treatment was carried out under laboratory conditions. The effects of cellulase treatment on weft knitted fabric regarding mechanical and surface properties were evaluated using the KES‐FB Kawabata evaluation system. The influence of enzyme treatments, friction, and geometrical roughness on the face and reverse side of interlock knitted fabrics were discussed in comparison with untreated interlock knitted fabric.

Findings

After each of the enzyme treatments, the interlock knitted fabrics lost part of their weight and, therefore, they became thinner. Furthermore, the extension properties become higher in both directions with regard to the untreated knitted fabric for all used enzymes and carried out treatments.

Originality/value

The paper usefully analyzes changes in the extension and surface properties of enzyme‐treated interlock knitted fabrics by investigating the influence of whole or enriched endoglucanases celullases of Trihoderma reesei under different treatment conditions.

Abstract

Examines the fifteenth 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

Purpose

The comfort and fit of clothes are affected by fabric properties, dressed ease and environmental conditions, in which dressed ease is influenced by the interaction among complex shapes of human body, style design and fabric mechanical properties.

Design/methodology/approach

In this study, the dressed ease distribution at waist section, which is related to body surface convex angle, was investigated using 3D scanning. A series of surface convex angles on bust and back were formed after adjusting the mannequin. The mannequin was scanned by TC2 separately in garments with eight different ease allowances. Then the dressed ease distributions at waist under different convex angles of body surface have been acquired by calculating the distance between waist points and dressed surfaces along normal directions.

Findings

The results showed that the body surface convex angle was weakly related to the dressed ease when the garments’ bust ease allowance was below 4 cm. When the garments’ bust ease allowance was within 6–12 cm, the body convex angle had a great impact on the dressed waist ease distribution in the condition of 26º–33º bust convex angle and 13.96º–17.96º back slope angle. For slack garments with more than 16 cm ease allowance, the dressed waist ease distribution did not relate to the bust convex angle, while it strongly related to the bust convex angle between 13.96º and 17.96º. The regression model was statistically significant between the dressed ease value and the body surface convex angle.

Originality/value

According to the dressed waist ease distribution of different body surface convex angles, this paper gives an application of pattern modification in order to optimize the waist fit. The results can provide guidance for the optimization of different body shapes. At the same time, the application of gap data to 3D virtual fitting can greatly improve the authenticity of virtual simulation effect.
