Abstract

Shows the necessity of developing powerful 3D CAD‐systems for the textile and clothing industry. The connection between 2D and 3D CAD‐systems enables the user to prepare a collection more quickly and accurately. Applications could be the drape behaviour of the fabric, the deformational behaviour of fabrics when covering defined surfaces and also technical textiles.

Abstract

In this paper a model is presented for the calculation by approximation of a drape test standardized in the textile industry. As woven fabric is of low thickness compared with the other dimensions, the fabric can be considered to be a two‐dimensional continuum. For the simulation model, the shell theory is taken as a basis. Simulating the drape behaviour presents a geometrically non‐linear field problem with considerable displacements.

Abstract

The new protective equipment forms a FARADAY cage, thus protecting the worker from unacceptably strong electrical fields as well as from being invaded by dangerous electric currents. The protective shielding clothing described is a personal protective equipment of the highest category. Therefore, it must be certified by an acknowledged examining and certifying authority. An application with regard to the attestation of conformity for this protective clothing hasbeen submitted to the Examination andCertification Section of the Expert Committee for Electrical Engineering.

Abstract

Complex material requirements for high‐technology applications increasingly demand the use of hybrid material structures with properties tailored to the lines of loading. Textile‐reinforced multilayer composite structures are particularly suitable for the production of component structures in an optimised lightweight construction. In the loading case, however, delaminating phenomena occur between the individual layers due to the low interlaminar shear strength. The appropriate techniques and machines of the ready‐made‐clothing technology allow the specific sewing‐up of the semifinished textile products into a three‐dimensionally reinforced multilayer composite structure; the setting of a load‐adapted and failure‐tolerant characteristic of properties being possible in the z‐direction through a versatile variation of sewing parameters. Moreover, the sewing technology makes possible a ready‐made‐clothing‐technological preassembly of components of semi‐finished products, and thus can perform position‐fixing functions in the consolidation of the composites. The ready‐made‐clothing process is divided into sub‐processes like product development, preparation of cutting, cutting, connecting and forming as well as packaging and shipping. The technical procedures and machines applied are chosen from economic aspects. Besides the large number of pieces, extreme thickness of the textile products of up to 20 mm and the required sewing precision demand precise and reproducible manufacturing processes.

Abstract

Purpose

The aim of the research is the development of 3D virtual models of lower female bodies from scanned data of different body types for computer‐aided 3D product development of loose‐fitting garments.

Design/methodology/approach

In order to develop reproducible construction of fashionable/functional outerwear (e.g. ladies’ trousers) on the basis of generated scalable 3D virtual female models, 3D‐CAD methods have to be developed. In doing so, the variable parameters are predefined and the block pattern of a trouser design can be modified by changing the parameters for the variety of trouser models. Two‐dimensional (2D) pattern pieces are then automatically generated and modified if necessary. According to morphological changes, the whole process proceeds automatically up to 2D patterns and thus corresponds to a grading in 3D.

Findings

The generated 3D virtual model and trouser design corresponding to a basic design or block pattern can be offered to the garment industry. The task of the designer or stylist is only to define the intended pattern design on the created trouser shell. Therefore, the approach is also very feasible for pattern makers who are not skilled in computer technology. The goal of this research is to provide an indispensable basis for an effective new technology for the construction of fit‐relevant, loose‐fitting garments, and in doing so, further accelerate the textile chain.

Originality/value

This paper provides methods of creating 3D garment design as well as grading in 3D, based on scalable virtual models of female lower bodies, which are worked out using a new German size designation system. Since the data processed for the generation of virtual models derives from direct scan data from women (taking into account different body types), the targeted German population is reflected.
