Bu çalışmada yenilenebilir kaynaklardan üretilen biyo bozunur ve biyo gübrelenebilir poli(L-laktik asit) (PLLA) polimerinden, eriyikten çekim eğirme prosesiyle filament iplikler üretilmiştir. Özel kesitli PLLA filament iplik üretimleri başarıyla gerçekleştirilmiş, bu kesitlerin sahip olduğu farklı yüzey morfolojilerinin ipliklerin yapısal ve fiziksel özelliklerine olan etkileri araştırılmıştır. Kesit şekilleri olarak en yaygın kullanılan dairesel kesitin dışında üçgen, artı, içi boş daire ve yassı biçimleri seçilmiştir. İpliklerin termal özellikleri ve kristalizasyon verileri DSC analizi ile, kimyasal özellikleri viskozite ve karboksil analizleriyle, fiziksel özellikleri ise mukavemet, uzama, düzgünsüzlük testleriyle karakterize edilmiştir. PLLA polimerinden eriyikten çekim eğirme prosesi ile endüstriyel özellikte özel kesitli filament iplikler başarı ile üretilmiştir.
In this study, filament yarns were produced from the biodegradable and bio compostable poly(L-lactic acid) (PLLA) polymer produced from renewable resources by the melt spinning process. Special cross-section PLLA filament yarn production was carried out successfully, and the effects of different surface morphologies of these sections on the structural and physical properties of the yarns were investigated. Triangle, plus, hollow circle and flat sections were chosen as the special cross section, apart from the most commonly used circular section. Thermal properties and crystallization data of the yarns were characterized by DSC analysis, chemical properties were characterized by viscosity and carboxyl analysis, and physical properties were characterized by tensile, elongation and evenness tests. Industrial quality special cross-section filament yarns have been produced successfully with the melt spinning process from PLLA polymer.
