Thermogravimetric, microscopic and mechanical analyses of pbt and pet yarns

Bu çalışmada, farklı tipte poliester ipliklerinin termogravimetrik, mikroskopik ve mekanik özellikleri incelenmiş ve karşılaştırılmıştır. Bu amaçla, PET esaslı normal poliester ipliği ve çeşitli özellikler (güç tutuşurluk, ultraviole koruyuculuk ve antibakteriyel) kazandırılmak için modifiye edilmiş poliester iplikleri ve PBT ipliği seçilmiştir. Elde edilen sonuçlara göre, normal PET ipliği ile kıyaslandığında, PBT ipliğinin daha düşük Tdi değerine, daha yüksek kömürleşmiş kalıntıya, daha düşük kopma mukavemetine ve benzer yüzey özelliklerine sahip olduğu tespit edilmiştir. Modifikasyon işlemleri arasında ise yalnızca güç tutuşurluk işleminin termal özellik üzerinde değişikliğe sebep olduğu anlaşılmıştır.

PBT ve pet ipliklerin termogravimetrik, mikroskopik ve mekanik analizleri

In this study, thermogravimetric, microscopic and mechanical properties of different types of polyester yarns were investigated and compared. To this goal, PET based regular polyester yarn and polyester yarns modified for various specialities (flame-retardant, UV protective and antibacterial) and PBT yarn were selected. According to the results, it was determined that PBT had a lower Tdi value, higher char residue, lower tensile strength compared to regular PET and similar surface characteristics to regular PET. Among the modification processes, only the flame retardancy process was found to affect the thermal property.
