Poliester (PET) lifleri tekstil endüstrisinde dünya genelinde en çok kullanılan sentetik liftir. Dünya genelinde çevresel ve ekolojik kaygıların artmasıyla sentetik liflerin geri dönüştürülmesi, ...biyobozunurluğunun sağlanması yönünde çalışmalar yapılmaktadır. Bu deneysel çalışmada poliester, geri dönüştürülmüş poliester (r-PET) ve biyobozunur poliester (bio-PET) içerikli kumaşların boyama ve fiziksel performansları karşılaştırılmıştır. Elde edilen sonuçlarda r-PET ve bio-PET içerikli numunelerin en az PET içerikli kumaşlar kadar iyi boyandığı haslık ve mukavemet değerlerinde belirgin farklılıklar olmadığı tespit edilmiştir. Bu kapsamda r-PET ve bio-PET liflerinin PET liflerine alternatif olabileceği düşünülmektedir.
Polyester (PET) fibers are the most widely used synthetic fiber in the textile industry worldwide. With the increasing environmental and ecological concerns around the world, efforts are being made to recycle synthetic fibers and to ensure their biodegradability. In this experimental study, the dyeing and physical performances of polyester, recycled polyester (r-PET) and biodegradable polyester (bio-PET) fabrics were compared. In the results obtained, it was determined that the samples containing r-PET and bio-PET were dyed at least as well as the fabrics containing PET, and there were no significant differences in fastness and strength values. In this context, it is thought that r-PET and bio-PET fibers can be alternatives to PET fibers.
The aim of this study was to assess the relationships between the course of Behçet's disease (BD), disease-specific fears, and work productivity and activity impairment.
In this cross-sectional ...study, 110 consecutive BD patients were included. The Work Productivity and Activity Impairment questionnaire was used.
In the group of employed patients, 30.41% had missed work during the previous week. The mean percentages of daily activity impairment were higher in patients with musculoskeletal involvement (39.81 ± 33.61%) compared to those without (23.48 ± 32.45%) (P = 0.008). A greater decrease in working hours was observed in patients with eye involvement (45.52 ± 15.29 h) compared to those without (54.15 ± 15.29 h) (P = 0.007). More of the male patients (67.8%) were afraid of losing their jobs compared to females (30%) (P = 0.000).
The highest levels of lost productivity and the most severe effects on daily life are consequences of eye and musculoskeletal involvement in the study population. More effective therapeutic approaches are required to improve the working lives of patients with BD. Moreover, male patients had a higher fear of losing their jobs, suggesting a match between the expected clinical course and the predictions of BD patients.
