In this study, production of multilayer surfaces for acoustic and thermal insulation was investigated. After the optimum textile materials had been chosen to provide acoustic and thermal insulation, surfaces were created using different relative methods in this field. Sublayer nonwoven produced from slotted polyester fiber was combined with two different top layers of fabrics, one of which was the top layer of fabric woven from plain weave obtained from texture yarns, which, in turn, was produced from hollow polypropylene, and the other was plain weave obtained from texture weft yarn, which was produced from conventional polypropylene fibers separately. Subsequently, these two different surfaces were combined with polyurethane-based material. Pumice stone powder in three different concentrations and two different sizes was added to enhance acoustic and thermal insulation, after which the sublayer had been coated with an adhesive material to produce multilayer adhesive force and adherence to the wall. Consequently, air permeability, sound absorption, and thermal conductivity coefficients of multilayer surfaces were researched with regard to the type of top layer of fabrics, concentration, and particle size of pumice stone powder. The results demonstrate that the properties of multilayer surfaces concerning acoustic and thermal insulation increase with the increasing concentration of pumice stone powder and with the decreasing sizes of pumice stone particles. In addition, air permeability of multilayer surfaces was ensued to decrease with the increasing concentration as well as particle size of pumice stone powder.

This study has aimed at the development of thermal insulation and adhesion properties of polypropylene (PP) fabric. The texture PP weft yarn, the texture weft yarn produced from hollow PP fiber and the nonwoven produced from PP fiber were used as three different raw materials, each of which was one-side coated with the mixture containing polyurethane and pumice stone powder with different concentrations in order to improve thermal insulation properties. Then the other sides of these fabrics were coated with polyacrylic ester based material so as to improve adhesion behavior of the fabrics. Finally, heat transfer coefficients of each fabric were analyzed in accordance with fabric type, concentration of pumice stone powder and polyacrylic ester based material along with adhesion properties. The results demonstrated that the increase in the concentration of pumice stone powder and the use of polyacrylic ester based material caused the decrease in the thermal conductivity coefficients. In addition, the use of polyacrylic ester based material brought in adhesion properties to fabrics in order for the ability to adhere these fabrics onto any surface.

Bu tez çalışmasında binalarda izolasyon amaçlı kullanılmak üzere ses ve ısı izolasyonu sağlayan duvar kumaşı üretimi incelenmiştir. Ses ve ısı izolasyonu sağlamaya yönelik optimum tekstil malzemeleri seçildikten sonra, farklı yüzey oluşturma teknikleri kullanılarak yüzey oluşturulmuştur. Kanallı poliester elyaf kullanılarak tarama yöntemine göre dokusuz yüzey, polipropilen ve içi boş polipropilen elyaf kullanılarak elde edilen tekstüre ipliklerden ise bezayağı desenine göre yüzeyler oluşturulmuştur. Ardından iki farklı yüzey adhesiv bir madde ile birleştirilmiştir. Katmanlı yapının ısı ve ses izolasyon özelliklerini geliştirmek amacıyla yapıya üç farklı konsantrasyonda ve iki farklı boyutta ponza taşı tozu aktarılmıştır. Çift katmanlı yapının duvara adhezyonun sağlanması için çift katmanlı yüzeyin bir tarafı adhesiv bir madde ile kaplanmıştır. Elde edilen duvar kumaşının portatif olması, istenilen her türlü renk ve desende üretilebiliyor olması, ses ve ısı izolasyonuna sahip olması ve her türlü duvara uygulanabiliyor özelliklerde olması tüketicinin beklentilerini karşılayacaktır.

In this study, cotton fabric was treated with oxygen, nitrogen and argon plasma application. The plasma application was carried out for 10 minutes at low frequency. Firstly, contact angle of plasma treated samples was measured at the end of plasma treatment. The results showed that the plasma treatment causes to increase the hydrophility of samples. Moreover, it was seen that the type of gas affects the hydrophilic properties of samples. After then the samples were left during 1 month with different conditions which were under normal condition and covered with aluminum foil. Finally, the contact angle of plasma treated samples was measured after 1 month in order to determine the durability effect of plasma treatment on properties of cotton fabric. After the contact angle measurements, the results were evaluated with statistical analyses in terms of the type of gas and storage conditions of plasma treated samples. The results demonstrated that the storage conditions and type of gas affect the hydrophilic properties of plasma treated cotton fabric after 1 month.

In this study, Polyester/Viscose (PET/CV) nonwoven fabrics were treated with oxygen plasma application. The plasma application was carried out for 1and 10 minutes at low frequency. After then, the samples were dyed with disperse dyes. Where same samples were dyed with carriers, the others were dyed without carriers. Finally, the effects of plasma treatment on dyeing properties of PET/CV nonwoven fabrics were investigated at 3% darkness. The aim of this study is that the effect of hydrophility caused by the plasma application on dyeability properties of samples was investigated.
