In this paper, the general features of b -cyclodextrin and their applications in the textile industry have been reviewed. The use of b -cyclodextrin in the textile industry is of great significance due to its wide range of application. One of the key aspects is the attachment technique of b -cyclodextrin to the textile's surface. This review deals with this in depth. Some quantification and characterization methods of Textile- b -cyclodextrin are discussed. In the last few years, the new direction in textile research is the functionalisation of textile systems. It is believed that b -cyclodextrin will play a very important role in these new developments. b -cyclodextrin can act as a host for various guest molecules. This enables the development of fabrics that release chemical compounds such as fragrances and antimicrobial agents. It is concluded that there are many possibilities for the development of new textile products with advanced properties based on b -cyclodextrin.

In this work, the thermal comfort properties of bamboo knitted fabrics have been studied in relation to loop length and yarn linear density. The objective was to determine the influence of fabric factors such as loop length and the constituent yarn linear density on the fabric properties such as air permeability, thermal conductivity, thermal resistance and relative water vapour permeability. Yarns with linear densities of 20s Ne, 25s Ne, 30s Ne with the same twist levels were used to construct the fabrics of single jersey structure with loop lengths of 2.7 mm, 2.7 mm and 3.1 mm. The anticipated increase in air permeability and relative water-vapour permeability with a decrease in yarn linear density and increase in loop length was observed. In general, the thermal conductivity and thermal resistance tended to increase with the constituent yarn linear density but decreased with an increase in loop length.

A flexible textile keyboard, using carbon nanotube (CNT) filled polypropylene (PP) composite fibres, is introduced. The identification of input information is achieved by reading the effective resistance of the conductive composite fibre. By using a single wire, a complex matrix is avoided and the interface between textiles and processing electronics is reduced to a minimum. LabVIEW has been used as the output display of the keyboard indicator for testing. This keyboard is fully flexible and washable, which provides opportunities for its integration with etextiles.

The paper deals with the testing of carboxymethyl cellulose properties. It was verified whether carboxymethyl cellulose soaked in water, salt solution or pH adjusted water resulted in better sorption properties than 100% cellulose represented by standardised cotton fabric. During the measurements the samples were dipped into water of different temperatures (10°C, 20°C, 30°C, 40°C, 50°C), in a NaCl solution (concentration 0.1g/l, 0.9 g/l, 5 g/l and 10 g/l) and in water with a modified pH (5, 7, 9). Another measure was aimed at monitoring changes in the structure of the textile samples soaked in water at a temperature of 20°C with subsequent drying, which was carried out using an electron microscope.
