Titanium dioxide exhibits photocatalytic properties under ultraviolet (UV) irradiation. In this study, an environmentally friendly, fast and efficient technique for bleaching cotton fabrics is ...presented, utilising the photocatalytic property of TiO2. Raw cotton fabric samples were treated with TiO2-containing and TiO2-free treatment solutions (hydrogen peroxide and sodium hydroxide) under UV irradiation in order to bleach the samples. The results showed that cotton fabrics treated with TiO2 were bleached satisfactorily without severe strength loss.
Due to water limitations and the growing global demand for raw materials, manufacturers and consumers are seeking more environmentally friendly alternatives. Polyester, a non-biodegradable fibre ...derived from petroleum, can be replaced with recycled polyester (r-PET), a sustainable alternative that reduces environmental impacts through the reuse of materials. The textile finishing industry, known for its high water and energy consumption, is calling for the development of low-water-consumption technologies. One innovative approach involves waterless dyeing procedures using a supercritical carbon dioxide (scCO2) medium that is particularly suitable for dyeing synthetic fibres. To assess its effectiveness, a study compared traditional water dyeing with scCO2 medium dyeing on woven fabrics made from both polyester (PET) and recycled polyester (r-PET) fibres with varying weights. After conducting tests on the dyed fabrics, the data revealed that r-PET fabrics dyed using a supercritical carbon dioxide (scCO2) medium appeared darker than fabrics dyed using traditional water dyeing techniques. Moreover, r-PET fabrics demonstrated better colour fastness. Notably, the K/Ssum values (measurement of colour intensity) of r-PET fabrics were at least as good as those of PET-based fabrics in all cases of dyeing, while the fastness values were similar for both PET and r-PET fabrics.
Zaradi omejitev pri porabi vode in naraščajočega svetovnega povpraševanja po surovinah proizvajalci in potrošniki iščejo okolju prijaznejše alternative. Biološko nerazgradljivi poliester na osnovi nafte je mogoče nadomestiti z recikliranim poliestrom (r-PET), trajnostno alternativo, ki s ponovno uporabo materialov zmanjšuje vplive na okolje. Industrija dodelave tekstila, znana po veliki porabi vode in energije, kliče po razvoju tehnologij z majhno porabo vode. Eden inovativnih pristopov vključuje postopke barvanja brez vode z uporabo superkritičnega ogljikovega dioksida (scCO2), ki je posebej primeren za barvanje sintetičnih vlaken. Da bi ocenili njegovo učinkovitost, so bile tkanine iz poliestrskih (PET) in recikliranih poliestrskih (r-PET) vlaken z različno ploščinsko maso primerjalno barvane po tradicionalni metodi v vodni kopeli in s scCO2. Tkanine iz r-PET, barvane v superkritičnem ogljikovem dioksidu, so bile videti temnejše od tkanin, barvanih s tradicionalno metodo z vodo. Poleg tega so tkanine iz r-PET imele boljšo barvno obstojnost. Vrednosti K/Ssum (merjenje intenzivnosti barve) tkanin iz r-PET so bile vsaj tako dobre kot tiste pri tkaninah iz PET v vseh primerih barvanja, medtem ko je bila obstojnost barv pri tkaninah iz PET in r-PET podobna.
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.

One of the developing branches of the textile industry is technical textile products. Building and construction technical textiles, which are among the technical textiles, are widely used in the building industry. The fact that building and construction technical textiles offer environmentally friendly, lightweight, high-performance, and sustainable solutions increases the use of these materials day by day. With this review, building and construction technical textiles (buildtech) were examined under subtitles and the studies carried out in this field in recent years were examined. Along with increasing environmental and ecological concerns, sustainable and innovative applications in building and construction technical textiles have come to the fore and this subject has been discussed in this review. According to the results obtained in this context; thanks to the superior properties provided by building and construction technical textiles, it is predicted that their use in the building industry will gradually increase.
