Soilless Cotton & Non-Petroleum Polyester- Potential Opportunities for Sustainability in Textiles

Today, most of people who start off for an environmentally friendly application do more damage to sustainability compared with conventional methods. 

Therefore, this book primarily aims to understand real sustainable production. 

Secondly, it is emphasized in this book that wastes of textiles and garments constitute a major environmental load. 

At this point, it is pointed out that recycling is the best solution for humanity. 

It is highlighted that recycling presents us the opportunity to obtain “soilless cotton” and “non-petroleum polyester”. 

This book examines these two recycled fibers that have important potentials for sustainability by using arguments obtained from the author's knowledges, experiences, researches and latest literature. 

Finally, it is pointed out that habitat provided by people who do the right things for sustainability are begun to be abused by malicious ones. 

This book describes how to become true environmentalists, how real environmentalists can recognized and the main principles of sustainability and recycling in textiles. 

This book gives suggestions to producer, consumer, academicians and researchers in this field.

Usage of Recycled Cotton and Polyester Fibers for Sustainable Staple Yarn Technology

In this study, yarns were produced from cotton fibers (CO), recycled cotton fibers obtained from yarn wastes (r-CO) and fibers produced from recycled PET bottles (r-PET).

Tensile strength, elongation at break, unevenness (CVm), yarn imperfections (IPI) values and hairiness properties of these yarns were measured.

The purpose of this study was to eliminate negative characteristics of recycled cotton and polyester fibers with using together by open-end spinning system.

There was no study about r-CO/r-PET blends in the literature.

This study was also given significant findings related to these blends.

This paper obtained results which corroborate the findings of a considerable number of the previous works in CO/r-CO and CO/r-PET binary blends.

Furthermore, this study contributes to the extant literature.

Commercialized Denim Fabric Production with Post-Industrial and Post-Consumer Wastes

The purpose of this study was to produce 100% recycled denim without a tradeoff in quality according to zero waste concepts.

Initially, the waste points from raw materials to final product in denim fabric production process were determined.

Then, denim fabrics were produced from post-industrial (recycled cotton fibers obtained from denim wastes) and post-consumer wastes (produced from recycled PET bottles).

Classic cotton fibers and alternative regenerated cellulose fibers (Tencel®) were used as carrier fiber in addition to mentioned fibers for eliminating recycled fibers disadvantages.

The effect of fiber types on yarn or fabric characteristics were investigated in accordance with planning design and construction.

Furthermore, the relationships between fibers and yarns/fabric results were statistically evaluated using correlation analysis.

The results of this investigation show that the amount of fibers have a significant effect on yarn unevenness, thick places, neps, hairiness, air permeability and abrasion resistance of the samples.

PET Şişe Atıklarının Tekstil Endüstrisinde Değerlendirilmesi ve Sürdürülebilirliğe Katkısı

ÖZET: Plastiklerin geri dönüşüm teknolojilerinde yaşanan gelişmeler, fiyat ve ekolojik avantajlar nedeniyle tekstil endüstrisi için yeni bir hammadde kaynağının oluşmasını sağlamıştır. Günümüzde tekstil sektöründe en fazla tüketilen  polimer olan Polietilentereftalat (PET) polimeri; çoğunlukla su, meşrubat vb. sıvı gıdaların piyasaya sürülmesi amacıyla kullanılan PET ambalajlardan geri dönüşüm tesislerinde PET talaşları olarak geri kazanılabilmektedir. PET talaşlarının eriyikten lif çekim yöntemi ile kullanılabilir life dönüşmesi de mümkündür. Bu çalışmada PET talaşlarının tekstil sektöründe kullanımı açıklanarak, Türkiye'deki PET talaş ve bu talaşlardan lif üreten işletmelerimizin durumu hakkında bilgi verilmektedir. Ayrıca Türkiye'de kurulu işletmeleri, bu alanda sahip oldukları teknolojik düzey bakımından, yurtdışındaki emsalleriyle karşılaştırma imkanı da olmuştur. Bu bağlamda, geleceğe yönelik bu alanda yapılması gereken yenilikler ve izlenmesi gereken stratejiler üzerine tavsiyelerde bulunulmaktadır.

ABSTRACT: Developments in plastics recycling enabled a new raw material for textile industry which creates economical and ecological advantages.Polyethyleneterephthalate (PET),which is the most consumed polymer in textiles recently, is recycled into PET flakes from bottles which have been used for water; oil, drinks etc. packaging. It is possible to spin fibers from melted PET flakes. In this study, usage of PET flakes in textile industry was explained. Based on this explanation, some information about the conditions of Turkish plants which produces PET flakes and fibers from these flakes were given. Moreover, Turkish recycle plants of PET fiber are compared with similar foreign plants in terms of technological background. In this context, some advices are given about developments which have to be accomplished and strategies in this field that should be followed.

Effect of Recycled PET Fibers on the Performance Properties of Knitted Fabrics

PET (polyethylene terephthalate) is mostly used in textile and packaging industries.

PET Bottle wastes are separated from other wastes and after that some processes are applied to obtain PET flakes, such as breaking, washing, drying and etc.

r-PET fibers are produced by melt spinning method from these recycled PET flakes.

r-PET fibers have already been used for secondary textile products like as carpet bottoms, sleeping bags and insulation materials. In this study usability of recycled PET fibers in apparel industry were researched.

Comparative investigations of bursting strength, abrasion resistance, air permeability, surface friction, circular bending rigidity and dimensional stability properties were done to knitted fabrics produced from r-PET and blends with PET and cotton fibers.

It was found that, instead of PET, r-PET fibers can be blended in certain amounts without compromising fabrics performance.

Utilization of Waste Yarns in Hair Interlining Industry

There has been an innovation need for utilizing fine yarn wastes nowadays.

In this study, probability of using yarn wastes in hair interlining industry has been investigated.

Information about hair interlining was given and production problems were investigated.

It was underlined that by using wastes these problems can be solved environment-consciously.

Mass per unit area, breaking strength, elongation at break, fiber blending ratio, circular bending stiffness, and dimensional change of standard and environment-friendly interlinings were tested and comparatively investigated.

Consequentially, environment-friendly hair interlinings produced from different yarn wastes have lower shrinkage results.

It was found that breaking strength, elongation at break, and circular bending stiffness results of the two fabrics had no remarkable difference.

With this study, suitable utilizing area for waste yarns were found and singeing and sizing steps of the production were eliminated.

In every sense, this study brings innovations for hair interlining production and makes contributions to the environment.
