Woven compression bandage (CB) is one of the elastic textiles that exert pressure on muscles. With a defined tensile strength, it is possible to create the required compression on the given body parts. This work aims to investigate the relationship between woven fabric deformation, porosity, and tensile stress properties of three main types of woven CBs. All bandage samples are applied on human leg using two- and three-layer bandaging techniques. Bandage porosity is calculated for all frames at different weave angles using NIS software. Woven bandage construction parameters which are given by the preparation of warp and weft yarns, twist, count, and density along with woven fabric weave, type of weaving, and finishing process are the main factors that influence the bandage properties. Several methods considering thread distributions have been developed to determine the woven fabric's porosity during the tensile stress. Experimental results confirm that bandage porosity is directly proportional to the bandage extension and weave angle that ranges from 44° to 90°. The novelty of candidate study is to introduce practical remarks to the patient for optimizing the required bandage pressure by suitable extension or applied tension or weave angle for two- and three-layer bandaging systems.

People are special. The importance and need for the research and development into medical and healthcare devices can never be overstated. In the 21st century, medical and healthcare devices play a more vital role in our lives than ever before. A wide range of materials are being used for producing numerous medical and healthcare devices for a variety of end use. In this manuscript, historical development of wound care dressings and products are reviewed. The characteristics and requirements of modern wound dressings are summarized. A core part is devoted to the description of the materials used in medical and healthcare devices. Selected synthetic polymers are listed with their applications in medical and healthcare devices. The advantages and limitations of fibres, metals, ceramics and composites are denoted. Textile structures are highlighted with their applications in medical and healthcare devices.

Polypropylene monofilament is selected to fabricate the mesh used for hernia repair, and the mesh is warp knitted on a Tricot machine with a compound needle (gauge E 18); an atlas structure is used. The mesh with 18 to 20 courses per centimetre has the best mechanical properties. The heat-setting conditions are confirmed on the basis of trials. It can be concluded that the heat-setting temperature between 125 °C to 128 °C and the time between 5 to 8 minutes benefit the mechanical properties of the mesh.

Wyselekcjonowano monofilamenty polipropylenowe, przeznaczone dla wytworzenia siatek stosowanych do wzmocnienia powłok mięśniowych przy operacjach przepuklin. Siatki w postaci dzianin osnowowych byfy produkowane na osnowarkach z igłami suwakowymi o rozmiarze E 18. Zastosowano splot atłasowy. Warunki stabilizacji termicznej ustalono na podstawie prób. Stwierdzono, że siatki poddane stabilizacji w temperaturze 125 -128°C, w czasie 5-8 minut wykazują dobre właściwości mechaniczne.

A significant part of medical, fibre-based materials are antibacterial textile fabrics which can be obtained by various advanced technologies. The application of new nano-technologies offers the possibilities of producing and implementing such products. In this work we present some preliminary tests concerning the irreversible immobilisation of poly(L,L-lactide) microspheres loaded with Triclosan onto viscose nonwoven structures. In the available publications concerning encapsulation techniques, there is no information on trials pertaining to the production of microspheres from poly(L,L-lactide) with Triclosan. The experiments described in this paper were divided into two parts: the synthesis of microspheres with Triclosan (carried out at the Polish Academy of Sciences, Łódź), and the attachment of microspheres to a textile fabric structure (carried out at the Textile Research Institute, Łódź). The results were quantified and the microbiological efficiency of the modified fabrics was examined.

Wśród włókienniczych wyrobów medycznych znaczącą grupę stanowią tekstylia o właściwościach antybakteryjnych, uzyskiwanych przez stosowanie różnych technologii. Zastosowanie nowych technik, związanych z wykorzystaniem nanotechnologii, stwarza nowe możliwości dla produkcji i zastosowania tych wyrobów. W poniższej publikacji przedstawiono wyniki wstępnych prac, których celem było sprawdzenie możliwości trwalej inkorporacji mikrosfer, zawierających triclosan, do struktury włókniny wiskozowej stanowiącej podłoże włókiennicze. Badania wykonano w Instytucie Włókiennictwa przy współpracy Centrum Badań Molekularnych PAN w Łodzi w zakresie przygotowania mikrosfer. Uzyskane wyniki oceniono ilościowo i na podstawie badań skuteczności mikrobiologicznej.
