Shows an approach to workplace design, employing a well‐known prescribed technological operation. Using a non‐linear optimization method, searches for the minimal value of the objective function with respect to the constraints determined by the human locomotive sytem and by the prescribed technological operation of sewing cloth parts. Demonstrates the usefulness of this approach with a sewing example, where the reference task is the movement of the operator’s arms with the defined velocity profile.

Demonstrates the modelling of the kinetic process when the sewing needle enters the fabric. To get an adequate mechanical model of the given problem, the function ‐ the mathematical model ‐ of the penetration force with respect to the fabric, the needle and the mechanism in the sewing machine must be developed. The fabric was modelled as a combination of warp and weft threads. Each thread from the fabric is modelled as an ideal elastic Hook’s material. Outlines the restrictions which needed to be made to get the mathematical model of the problem.

Here parameter determination of a chosen rheological model of a yarn on the basis of the experimental results is shown. The Kelvin‐Voigt linear viscoelastic model of a solid material was chosen. The real yarn was used in the tear experiment. The knowledge of the stress‐strain curve is the measurement for the determination of the rheological parameter. The calculation of the Kelvin‐Voigt’s parameters, with respect to the known stress‐strain curve of the real yarn, is done with an optimisation method. In this numerical procedure the area between the response of the real yarn and the yarn model is minimised. The optimisation results show good coincidence of the real mechanical properties of the real yarn with the Kelvin‐Voigt rheological model. The model of the yarn enables simulation of real processes, which is easier because observation of the real systems are then not necessary, which is easier, more transparent and cheaper.

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.

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.

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.

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.

Discusses the 6th ITCRR, its breadth of textile and clothing research activity, plus the encouragement given to workers in this field and its related areas. States that, within the newer research areas under the microscope of the community involved, technical textiles focuses on new, ‘smart’ garments and the initiatives in this field in both the UK and the international community at large. Covers this subject at length.
