Recently, efforts at development of functional textiles with antibacterial effect have accelerated, the purpose being to provide protection against airborne bio-particles and micro-organisms. Growth of microbes on surface of textile materials can be inhibited by biocidal approach and biostatic approach. This paper describes the development of a healthcare textile with durable antibacterial properties by optimizing the conventional and commercialized antimicrobial agent polybiguanide derivative—poly(hexamethylenebiguanide) (PHMB). Pad-dry-cure method was used to coat PHMB on cotton fabrics. The durability to simulated healthcare laundering of the fabric samples was evaluated in detail. Specifically, effects of detergent and washing cycles were examined. It was found that the optimum finishing condition can impart to the fabrics excellent durability for simulated healthcare washing. The fabric samples showed 100% bactericidal effect after 52 washing cycles, and 104 washings slightly reduced the bactericidal activity. Nevertheless, both simulated healthcare washing and coating treatment were found to have slightly negative influence on the hand feel and tearing strength properties of cotton fabrics.

The paper presents the results of the researches carried out for obtaining multifunctional textile materials with multiple effects, by means of superior finishing techniques, using functional chemicals in the form of aqueous dispersions. It has been studied the possibility of combining treatment with dispersions with photocatalytic and antibacterial effects with a hydrophobic/oleophobic treatment that simultaneously provides both sustainable photocatalytic and antibacterial effect as well as hydrophobic/oleophobic effect within satisfactory limits for all these effects. The results of the laboratory evaluations performed on 50% cotton and 50% functionalised HT polyamide textile fabrics showed that hydrophobization treatment with fluoropolymer dispersions can be combined with the treatment with titanium dioxide photocalatytic dispersions or silver chloride and titanium dioxide dispersions to obtain multiple photocatalytic, antibacterial and hydrophobic/ oleophobic effects without diminishing the functionalization effects that would have been achieved by individual treatments

Abstract The elaborated principles of nanoengineering of linen textile materials implement the techniques of spatially localized effects of protein catalysts on polymeric cellulose companions with selective splitting of impurity compounds without damaging technologically necessary nano-sized formations of binders in the fiber structure. The ranges of optimal values of the residual content in flax fiber prepared for spinning are identified on the basis of the analysis of the successive stages of enzymatic and peroxide treatments contribution to the breakdown of polymers and the differentiation of the influence of impurities on the yarn technological properties. The recommended level of residual pectin, lignin and hemicellulose (wt. %) is: after enzymatic treatment P1 = 1,0±0,1; L1 = 3,9±0,3; Hc1 = 11,0±1,0; after peroxide bleaching P2 = 0,4±0,05; L2 = 2,3±0,3; Hc2 = 7,5±0,5. The required level of fiber structural modification at the stage of preparing roving for spinning can be achieved through use of protein catalysts whose globule size is 50...100 nm. The use of enzymes with these dimensional characteristics helps to ensure breaking of polymer adhesives on the surface of incrusts and in the areas of intercellular formations, which hinder fiber crushing, without damaging nano-sized binding fractions. The implementation of this method contributes to a significant improvement in the uniformity of structural and physical and mechanical properties of flax yarn. Increase in yarn fineness and strength properties of semi-finished products, as well as improvement of deformation properties and reduction of yarn breakages during the spinning processes are achieved.

In particular, to investigate the dependence of the complex reflection coefficient of ultrasonic waves on the total thickness and basis weight of textile material. Methodology. The analytical part of the study consisted in obtaining an expression for the complex reflection coefficient of ultrasonic waves and in modeling its dependence on the thickness and basis weight of different textile materials. The proposed method of control of these technological parameters consists in irradiation of textile materials with ultrasonic waves with the subsequent reception of the waves reflected from textile material, their digitization and carrying out the computer analysis of the received results. Findings. Analytical expressions are obtained that relate the thickness and basis weight of single-layer canvases, two-layer textile bags with a complex spatial structure, on the one hand, and the reflection coefficient of ultrasonic waves from such materials, on the other hand. Analytical calculations were made and mathematical modeling was performed based on the results of theoretical research. Originality. As a result of theoretical studies, it is determined how the thickness and properties of each  of  the  two layers  of porous textile  materials  affect  the  reflection of  ultrasonic  waves.  This  makes it possible on the basis of ultrasonic measurements to determine both the total thickness of textile materials and their basis weight with the accuracy required for their production.  Practical  value.  The  obtained  analytical  dependences  are  another  step  towards  the  creation  of control and measuring equipment to determine the properties of single-layer textile fabrics and two-layer porous  textile  bags.  This  will  help  determine  the  overall  thickness  and  basis  weight  of  materials  with  a complex spatial structure.

Conductive Textile

The conductivity of textile fabrics is not only relevant for highly conductive textile materials, which can be prepared by coatings with fine metal layers or conductive polymers, but it is also of large interest in antistatic or other textiles which necessitate relatively low conductivities. These high resistances are usually in a range of gigaohms to teraohms which is not accessible by common multimeters, but necessitates special teraohmmeters. Although these measurement instruments are not unusual in the textile industry, their applications necessitate knowledge of the measurement principle and especially of the influence of environmental conditions on the measurement results. Here, temperature- and humidity-dependent measurements for temperatures of 20°C/23°C/27°C and relative humidities of 50%/65% with a teraohmmeter on different textile fabrics are shown. The results show not only the strong impact of the environmental conditions, resulting in resistance deviations of more than one order of magnitude, but also give hints on how these environmental conditions can be stabilized to a large amount to enable reliable comparison between different textile materials.

A new measurement apparatus was developed to characterize the dynamic liquid moisture transfer properties of textile materials such as textile fabrics, based on the mechanical equipment, microelectronics, sensors and control system. Derived from the test data, five indices were defined to characterize the dynamic liquid moisture transfer difference between two surfaces of textile fabrics. The test principle and the evaluation method for the dynamic moisture transfer difference between two surfaces of textile fabrics were introduced. Six types of fabrics made from different textile materials were measured. The one-way ANOVA analysis was carried out to identify the significance of the differences of the indices among the test fabrics. The results show that each evaluation index is significantly different (P<0.05) among different test fabrics, and fabric 3 has a better liquid moisture transfer from inner surface to outer surface with the highest value of moisture transfer difference.
