Woven, knitted and braided fabrics for medical textile products are made from yarns that contain fibers, whereas nonwoven fabrics can be made directly from fibers or even polymers. Expanded PTFE fabrics and electrospun webs of micro and nano denier fibers, used in medicine, are examples of products made directly from polymers. All fabrics mentioned vary widely in their construction parameters and, therefore, in the performance characteristics obtained from a given raw material. There is, therefore, a hierarchy of structure. The performance of a final product can be modified from two to four levels of organization. 

In western Europe, the production and consumption of medical textiles have grown since the 70s. In the 80s, comfort, convenience and cost were clearly the priorities when determining a desirable surgical gown or drape. In the 90s, however, concern for safety became the driving force behind medical fabric selection, with a serious new focus on barrier properties. Table 12.5 shows the end-use consumption of nonwovens for medical purposes until 2005. This increase is related to the appearance of new and dangerous infection diseases. The physician needs to be protected from the patient because of the transmission of blood-borne pathogens. 

The purpose of antimicrobials in medical textiles such as wound dressings is to eithCT prevent infection from occurring or to contribute to the healing of infected wounds, and odour control is a subsidiary effect whereas, the inclusion of activated charcoal in wound dressings is specifically to manage odour. Activated charcoal cloth (ACC) is sandwiched/encapsulated between two layers of a polyamide nonwoven fabric. The ACC with silver has to be in close contact with the wound s surface in order for the silver ions to react with the bacteria causing the infection (Mcqueen, 2011).

Medical textile products used in hospital wards include bedding, clothing, mattress covers, incontinence products, clothes, and wipes. Incontinence products for patients are available in both diaper and flat-sheet forms, with the latter being used for bedding. Cloths and wipes are made from tissue paper or nonwoven-bonded fabrics, which may be soaked with an antiseptic finish. 

The use of polypropylene in textiles is steadily becoming more prevalent due to its lower cost basis. Polypropylene is commonly used in the fabrication of textile (nonwoven) filters for medical applications. In its native state, polypropylene nonwoven filtration media can only wet-out with liquids which possess surface tensions less than 32 mN/m. As such, water filtration requires high pressure to pass through the membrane. The use of an oxidative atmospheric pressure plasma treatment significantly increases fiber surface hydrophilicity and therefore filtra-... 

After a fiber or yam is produced, it is then fabricated into a textile stmcture in order to obtain the desired form, shape, and mechanical properties for a medical device. There are four alternative types of textile stmctures that are typically used for medical devices. They include wovens, knits, braids, and nonwovens. Each stmcture has its own advantages and disadvantages. For example, woven fabrics are usually stronger and more dimensionally stable and can be fabricated with lower porosities, but are stiffer, less flexible, and more difficult to handle. Knits, on the other hand, have higher permeability and flexibility compared to woven fabrics, but may dilate after implantation. Braids have high longitudinal tensile properties, but can be unstable when subjected to torsional loads. Thus, the type of textile stmcture should be carefully selected when designing the biotextile device, and the medical application and the site of implantation should be taken into account. 

The DCSBD source was originally designed to fulfill the specific requirements of the textile non-woven industry for hydrophilization of lightweight (i.e., with the thickness on the order of 0.1 mm only) PP-nonwoven (NW) fabrics, which are widely used in personal care absorbent products, such as, feminine hygiene products, diapers, adult incontinent products, and medical products, such as.
