Properties investigation of polyester yarns with different cross-sections

Abstract

In this work, the properties of polyester filaments with different cross-sectional shapes were investigated. Trilobal, flat and hollow shaped polyester filaments, having the same count, were produced by following the same route and production parameters. Properties, such as tensile strength, elongation, breaking load, unevenness etc., were investigated. Comparative evaluations of the test results with regard to the cross-sectional shapes were carried out. The results showed that cross‐sectional shape of the filaments directly affected the yarn properties and trilobal filament containing polyester yarns showed better properties as compared to yarns containing filaments with a cross-sectional shape of hollow and flat.

Properties investigation of polyester yarns with different cross-sections

Abstract

Bu çalışmada, farklı enine kesit şekillerine sahip polyester filamentlerin özellikleri araştırılmıştır. Aynı numaraya sahip olan trilobal, yassı ve hollow (içi boş) polyester filamentler, aynı yol ve üretim parametreleri izlenerek üretilmiştir. Çekme mukavemeti, uzama, kopma yükü, düzgünsüzlük vb. özellikler incelenmiştir. Enine kesit şekillerine göre test sonuçlarının karşılaştırmalı değerlendirmeleri yapılmıştır. Sonuçlar, filamentlerin enine kesit şeklinin iplik özelliklerini doğrudan etkilediğini ve trilobal filament içeren polyester ipliğin, içi boş ve yassı enine kesitli filamentleri içeren ipliklere kıyasla daha iyi özellikler gösterdiğini göstermiştir.
