Polypropylene applications nonwoven fabrics

Tapes for component supply in loading installations usually consist of an acrylate- or rubber-based adhesive (also thermosetting) on a paper or polyester foil carrier (dependent on the mass of the components). Depending on the type of application, different materials are used for the adhesive and the carrier for covering tapes. Most important carrier materials are foils (PVC, polypropylene, cellulose, polyester, polyimide), papers, and woven and nonwoven fabrics (cotton, glass). Adhesives frequently used are based on rubbers, silicones, and acrylates. Carrier less adhesive foils are used, for example, for the bonding of copper foils and polyimide films to get special base materials for circuit boards.

In this research, cetyl trimethyl ammonium bromide (CTAB), as an arrtimicrobial ent is applied on polyester, polypropylene and viscose non-woven fabrics alone and in combination with a Fluorochemical (FC 1112). The antimicrobial, water and blood repellency of the treated samples were investigated. To reveal the antimicrobial properties of the treated samples, the zone of inhibition and reduction of bacteria were measured with S. aureus, E. coli and P. aeroginosa. The results showed a good antimicrobial property on different concentration of CTAB solutions (1%, 2%, 4% and 8%). Application of CTAB with concentration of (0.5%, 1% and 2%) on polyester, polypropylene and viscose nonwoven fabrics indicated a reasonable antimicrobial effect Co-application of CTAB with fluorochemical on different samples also showed a good antimicrobial, water and blood repellency properties.

Polypropylene films are used in a variety of packaging applications. Both oriented and non-oriented films are used. Film tapes are used for carpet backing and sacks. Foamed sheet is used in a variety of applications including thermoformed packaging. Fibers are another important apphcation for polypropylene, particularly in carpeting, because of its low cost and wear resistance. Fibers prepared from polypropylene are used in both woven and nonwoven fabrics. 

Lee et al. explored the application of zinc oxide nanoparticles to polypropylene nonwoven fabrics via electrospinning as one approach to impart UV-protective properties. In addition, moisture and air vapor transport characteristics of layered clothing systems with various levels of electrospun mat area density are assessed to observe the consequence of electrospun web layers on thermal comfort level of the layered structures (Fig. 14.6c) [56]. Ultrafine cellulose fibers from natural cotton lines, whose degree of polymerization was above 10,000, were electrospun. The cellulose nanotibers treated with the hydrothermal incorporation of Ce02 nanoparticles into the nanofiber substrate surface showed good UV-shielding properties... 

Industrial applications of polyolefin fibers include woven and nonwoven geotextiles, agriculatural fabrics, construction sheeting, automobile fabrics, filtration media, rope/twine, woven bags, narrow-woven web and tapes, tents, and tarpaulins. Geosynthetic fabrics will continue to be a growing market for polypropylene nonwovens. 

The polyolefins--particularly polypropylene—have found a number of applications particularly in home furnishings and industrial fabrics. Uses include indoor-outdoor carpeting, carpet backing, upholstery fabrics, seat covers, webbing for chairs, nonwovens, laundry bags, hosiery and knitwear (particularly as a blended fiber), fishnet, rope, filters, and industrial fabri cs. 

Polypropylene nonwovens have especially been the focus of research to enhance colorfastness properties of the material because of Its excellent chemical resistance, high melting point, low cost, and adaptability to many fabrication methods. To date, the poor dyeability of polypropylene has limited optimization of its applications in the manufacturing of yarns and knit fabrics, upholstery fabrics, and industrial fabrics. 

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-...
