Recycling of materials such as textiles, plastics, glasses, papers and metals instead of storing, burying or burning results a reduction in raw material demands of industry. This means also that a reduction in amount of money, time and energy spent on to obtain raw materials. From this point of view, the main purpose of this study was determined as the production of textile surfaces with high waste fiber content by recycling textile fiber wastes in sizes that cannot be used in the textile manufacturing industry again. In this sense, various composite plates that can be used for sound and heat insulation on the exterior and interior surfaces of the buildings were produced by using unconventional methods from the waste fibers varying in lenghts of 1-25 mm. The effect of changed parameters such as density, fiber type, waste fiber ratio and aluminum foil layer addition were investigated. As a result of the tests, it was observed that the thermal conductivity coefficient values of the all produced composite panels varied between 0.033-0.038 W/mK, and the sound transmission loss values between 24.2-32.6 dB.
The aim of this study is to reach closer results to the actual measurements by using artificial neural networks in evaluating the properties of single and double layer woven fabrics that affect the end user. The variation of the most important parameters such as breaking strength, weight, thickness, tearing strength properties to meet the end user's needs depending on the yarn count and the weaving type was investigated. In the fabrics produced in this study, cotton yarn was used as weft yarn in three different numbers and 90 denier polyester yarns were used as warp yarn. Plain, twill, panama, warp rips and satin were used as weaving type. Fabrics were weaved in three different weft frequencies. Evaluations using artificial neural networks were found to give closer results to the actual measurements.Citation: Turker E, Turan NY.

Dünya nüfusunun hızla çoğalması ve insanoğlunun sürekli değişen yaşam standartları nedeniyle atık miktarının giderek artmasıyla birlikte doğa hızla kirlenmektedir. Bununla birlikte, hızla gelişen teknolojilerin üretimi ve kullanımı sırasında ortaya çıkan gürültüler ve elektromanyetik alanlar ise insan yaşamını etkileyen diğer bir kirliliği oluşturmaktadır. Türkiye sanayisindeki endüstriyel katı atık miktarının yaklaşık %5'ni tekstil ürünleri imalat atıkları oluşturmaktadır. Bu bağlamda tekstil sektörü için geri dönüşüm ve katma değerli ürün üretimi konuları önemini arttırmaktadır. Bu çalışmada, tekstil imalat atıklarının geri dönüşümüyle elde edilen tekstil yüzeylerinin, ses yalıtımı, ısı yalıtımı ve elektromanyetik kalkanlama testlerinde ne ölçüde etkin olduklarıyla ilgili literatür araştırması yapılmıştır. Literatür araştırması sonucunda, bu tekstil yüzeylerinin performansları değerlendirilerek, düşük maliyetli yalıtım ve kalkanlama özelliği gösteren ürünlerin tasarımında ve üretiminde ileride yapılacak çalışmalara katkıda bulunulması amaçlanmıştır.
