Ardışık Bitim İşlemi Görmüş Polipropilen Esaslı Dış Mekan Kumaşların Antimikrobiyel ve Su İtici Performanslarının İncelenmesi

Öz

Dış mekân tekstilleri kapsamında en çok tercih edilen kumaşlardan bir tanesi polipropilen esaslı kumaşlardır. Son yıllarda pandeminin oluşturduğu risklerden dolayı dış mekân tekstillerinden antibakteriyel, antivirüs, küf önleyebilen bir takım ilave özellikler de beklenmektedir. Antimikrobiyel bitim işlemi ve su itici işlemler polipropilen kumaşlara ard arda uygulanabilmektedir. Bu çalışma farklı oranlarda antimikrobiyel (0,5, 10 gr/lt) ve florokarbon esaslı su itici (0, 30 ve 50 gr/lt) kimyasalların ard arda uygulanmasıyla elde edilen dış mekân kumaşların antimikrobiyal etkinlik ve su itici seviyelerinin araştırılmasını hedeflemektedir. İstatiksel sonuçlara göre; S. aureus ve C. albicans mikroorganizmalarına karşı antibakteriyel etkinlik, proses türünden 0,05 anlamlılık seviyesinde etkilenmektedir. Polipropilen esaslı dış mekân kumaşları genel olarak S. aureus mikroorganizmasına karşı daha etkili bulunmuştur. Aynı miktar antimikrobiyal madde ile işlem gören kumaşlarda, uygulanan su itici madde miktarı arttıkça, su iticilik seviyeleri genel olarak iyileşmiştir.

ANTIMICROBIAL AND WATER REPELLENCY PERFORMANCE OF POLYPROPYLENE OUTDOOR FABRICS SUBJECTED TO SEQUENTIAL FINISHING PROCESSES

Öz

Polypropylene fabrics are one of the most preferred products for outdoor textiles. With the risks posed by the pandemic in the last year, outdoor textiles are expected to have some additional features such as antibacterial, antivirus, antimildew properties. Antimicrobial finishing and water repellency treatment may be applied consecutively on polypropylene fabrics. This research aims to investigate the effect of sequential finishing process by applying of different antimicrobial chemical ratio (0, 5 and 10 g/l) and fluorocarbon-based water repelling substance (0, 30 and 50 g/l) on antimicrobial efficiency and water repellency grades of outdoor fabrics. According to the results of statistical analyses, it was determined that antimicrobial efficiency against S. aureus and C. albicans was statistically influenced from process type at significance level of 0.05, while antimicrobial efficiency against E.coli microorganism was not statistically influenced from process type. Antimicrobial activity of outdoor samples was more satisfying against S. aureus microorganism. Water repellency results generally improved as the applied amount of water repellent substance increased for the fabrics treated with the same amount of antimicrobial substance.
