Abstract
Additional processing steps in textile manufacturing such as reprocess in finishing department have severe unforeseen effects on sustainability. Here, we present a Life Cycle Assessment cradle-to-gate analysis of 100% cotton and 50% cotton/50% polyester T-shirts with and without reprocess. In the assessment, the functional unit is Medium (M) size short-sleeve polo necked T-shirt. Results showed that water footprint of fibre production, the global warming and abiotic depletion potential of the manufacturing step are the major factors that increase the environmental impacts. In 100% cotton T-shirt manufacturing, removing reprocess decreased the acidification, eutrophication potential, and water scarcity footprint. In the raw material (chemicals) step of cotton/polyester T-shirt production, the reprocess significantly increased the ozone layer depletion and abiotic depletion potential. Results suggest that reducing/eliminating reprocess in finishing department could decrease the environmental impact of apparel production by minimizing the use of chemicals, water, and energy.

Abstract
Tekstil imalatında ek işlemler, örneğin terbiye işletmesindeki işlem tekrarları, sürdürülebilirlik üzerinde öngörülemeyen ciddi etkilere sahiptir. Bu çalışmada işlem tekrarı yapılan ve yapılmayan %100 pamuk ve %50 pamuk/%50 polyester T-shirtlerin, beşikten kapıya (cradle-to-gate) Yaşam Döngüsü Değerlendirme analizi yapılmıştır. Değerlendirmede fonksiyonel birim orta (M) beden kısa kollu polo yaka T-shirt olarak seçilmiştir. Çalışma sonuçları, lif üretiminin su ayak izi, konfeksiyon üretiminin küresel ısınma ve abiyotik tükenme potansiyelinin çevresel etkileri artıran başlıca faktörler olduğunu göstermiştir. %100 pamuklu T-shirt üretiminde, işlem tekrarı gerçekleşmediğinde, asidifikasyon, ötrofikasyon potansiyeli ve su kıtlığı ayak izinde azalma sağlanmıştır. Pamuk/polyester T-shirt üretiminin hammadde (kimyasallar) aşaması değerlendirildiğinde, işlem tekrarının, ozon tabakasının incelmesi ve abiyotik tükenme potansiyelini önemli ölçüde arttırdığı görülmüştür. Sonuçlar, yaş işlem tekrarının azaltılmasının/elimine edilmesinin, giysi üretiminin çevresel etkisini, kimyasal, su ve enerji kullanımını en aza indirerek, azaltabileceğini göstermektedir.
