Follows a presentation at a symposium in 1993 where the authors presented an experimental investigation on a fluttering membrane for use in a wind‐tunnel. Analyses the fluttering of an object by a theoretical method. Compares the experimental results with those of the theoretical and discusses their effectiveness. States that the present analysis is effective for approximate investigations.

Presents the mechanical models of ring, rotor and air‐jet staple yarn formation. The analysis of formation peculiarities has enabled the establishment of differences among them in micro‐ and macrostructure as well as in their mechanical and physical properties. The comparison of yarn and fabric quality parameters will be very valuable for weavers, knitters, garment manufacturers, finishers and designers. Gives productivity, spinability and economic factors for ring spinning, OE‐rotor and air‐jet spinning processes.

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.

Selection of suitable sewing needle is one of the most important parameters for ensuring an effective and fault‐free sewing process. This task requires good knowledge of basic characteristics of a sewing needle, i.e. needle type, point shape and needle fineness. Also good knowledge of sewing materials is required. The contribution presents an analysis of important parameters that influence the sewing needle selection in women’s underwear production. The importance of those parameters in ensuring the appropriate seam quality is described. The selection of a suitable sewing needle was carried out on the basis of analysis of influential sewing parameters with application of machine learning from examples.

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.
