Closed-Loop Recycled Yarn Production from Yarn Wastes and Investigation of Their Physical Properties within the Scope of Sustainability

Recycling in textile is very popular in terms of sustainability, and a lot of studies were made by many researchers in this area and are still being made. In this study, yarns containing 10-50% waste using cotton as the main fiber were obtained in 3 different yarn counts, Ne 10, Ne 20, and Ne 30, and it was aimed to reveal the effects of waste on yarn properties. As a result of the graphical and statistical evaluations of the obtained data, it was determined that the waste did not affect the yarn properties as negatively as expected. Ne 10 is the most suitable yarn count in the production of waste yarn, considering that the waste content and ratio in the blended yarns affect the yarn properties less and even do not make a significant difference. The optimum blend ratio of waste, in terms of yarn unevenness and yarn imperfections, is 30%. While a 30% waste rate is the most suitable in terms of all properties of Ne 20 yarns, it seems reasonable to obtain yarn with lower waste rates in Ne 30 yarns in terms of hairiness and breaking strength.

İplik Atıklarından Kapalı Döngü Geri Dönüşüm İplik Üretimi ve Fiziksel Özelliklerinin Sürdürülebilirlik Kapsamında Araştırılması

Tekstilde geri dönüşüm sürdürülebilirlik açısından oldukça popülerdir ve bu alanda birçok araştırmacı tarafından birçok çalışma yapılmış ve yapılmaya devam etmektedir. Bu çalışmada, Ne 10, Ne 20 ve Ne 30 olmak üzere 3 farklı iplik numarasında, ana lif olarak pamuk kullanılarak %10-50 telef içeren iplikler elde edilmiş ve telefin iplik özelliklerine etkilerinin ortaya çıkarılması amaçlanmıştır. Elde edilen verilerin grafiksel ve istatistiksel değerlendirmeleri sonucunda telefin iplik özelliklerini beklendiği kadar olumsuz etkilemediği belirlenmiştir. Harmanlanmış ipliklerdeki telef içeriği ve oranının iplik özelliklerini daha az etkilediği ve hatta önemli bir fark yaratmadığı düşünüldüğünde, telef iplik üretiminde Ne 10 en uygun iplik numarasıdır. İplik düzgünsüzlüğü ve iplik hataları açısından teleflerin optimum karışım oranı %30'dur. Ne 20 ipliklerin tüm özellikleri açısından %30 fire oranı en uygunu iken, Ne 30 ipliklerde tüylülük ve kopma mukavemeti açısından daha düşük fire oranlarına sahip iplik elde etmek makul gözükmektedir.
