In this dichotomous study, the silicone-based softeners were produced with the contribution of some additives such as glycerin, polyethylene glycol 400 (PEG 400) and polyethylene glycol 4000 (PEG 4000) which had hydrophilic hydroxyl groups for providing or developing the hydrophilic character, lubricity and filling properties of the emulsions. The paper aims to discuss this issue.

The produced softeners were applied to the 100 percent cotton-knitted fabrics at different concentrations (owf%). In the first part of the study, the produced silicone emulsions were characterized via particle size, polydispersity index (PDI), zeta potential and TGA analyses. In addition, the effects of these emulsions on the mechanical properties of the fabrics were examined by bursting strength and pilling tests, and also the whiteness degrees (Berger value) of fabrics were researched. In the second part of the study, the effects of produced silicone softeners on the comfort properties of the fabrics were investigated.

According to the results, it was possible to say that the additives could be successfully added to the silicone emulsions, and they did not have a crucial effect on the properties of the emulsions or the mechanical and whiteness properties of the fabrics.

In this study, the additives were used as single form in the softeners recipes; however, their dual or trio combinations and/or their different concentrations could be used in the softeners emulsions.

In order to enhance the hydrophilic character, the lubricity and filling properties of the silicone softeners, they could be produced by using appropriate additives.

The contribution of the additives to the recipes of the silicone softeners is a novel approach.

The purpose of this paper is to investigate the effects of silicone-based softeners, which were developed with different particle sizes (nano, micro, and macro) and chemical structures, on the performance of 100 percent cotton fabrics knitted with different type of yarn (ring, open-end, and compact).

In the study, the silicone emulsions having expected particle sizes were produced at laboratory conditions. The produced silicone emulsions were applied to knitted fabrics with both padding and exhaust methods at different concentrations. Some characterization tests (particle size and zeta potential) were applied to the silicone emulsions before the applications. After the applications, CIELab values, whiteness and color fastness, hyrophility, abrasion, pilling, bursting strength, and stiffness performances of the samples were tested. The changes of the investigated properties were also examined via ANOVA.

According to the results, it was found that the silicone applications caused the CIELab values, whiteness degree, hyrophility, pilling, bursting strength and stiffness performance of the fabrics to change depending on the particle sizes of the emulsions, the yarn type of the fabrics, the application type, and the concentration of the silicone emulsions. When the ANOVA results were examined, it was seen that the types of the yarn and the silicone emulsions were the most effective working parameters on the results.

Because no additives were added to the produced silicone emulsions, in the future research, they can be developed with the use of some additives. Thus, it can resolve some of the disadvantages of the silicone emulsions on the textiles.

While applying the silicone softeners to the knitted fabrics, the type of the yarn and the particle sizes of the emulsions must be determined according to each other, in order to obtain enough handle performance without causing negative change on the other important properties of the knitted fabrics.

When the studies regarding silicone softeners were investigated, it was found that there were no studies about the effect of the silicone softeners having different particle sizes on the physical and chemical structures of the knitted fabrics depending on the type of yarn and some working parameters such as concentration and type of the application.

In this study, which is divided into two parts, the silicone softeners having different properties and including different additives as glycerin, polyethylene glycol 400 (PEG 400) and polyethylene glycol 4000 (PEG 4000) (due to their high hydrophilic characters) are produced for the purpose of providing or developing the hydrophilic character, lubricity and filling properties of the emulsions. The paper aims to discuss this issue.

In the first part of the study, the produced silicone emulsions were characterized and applied to the 100 percent cotton-knitted fabrics. In addition, the mechanical properties and whiteness degrees of the fabrics were also researched. In this part of the study, the effects of the produced silicone softeners on the comfort properties of the fabric samples were investigated by qualitative handle, hydrophility, contact angle, air permeability, thermal comfort and moisture management tests.

The results showed that while classic silicone application improved mechanical comfort properties of the samples such as the handle and drape properties, they worsened other thermal comfort properties as hydrophility, transfer or dispersion of the moisture, and air permeability. In addition, the thermal comfort properties about heat transfer of the fabric samples were not significantly affected by application of the silicone softeners. All results were affected from the producing recipe of the silicone softeners, and generally the usage of the additives had positive effect on the comfort results depending on the producing recipe (especially type of the silicone oil) of the silicone softeners.

In this study, the additives were used in single form; however, their dual or trio combinations and/or their different amounts can be used in the emulsions.

In order to enhance the hydrophilic character, lubricity and filling properties of the silicone softeners, they could be produced by using appropriate additives.

In the literature, there were not any studies about the silicone softeners including different additives. So the authors can say that the contribution of the additives to the recipes of the silicone softeners is a novel approach.

Nowadays, the usage of antibacterial textiles is very popular for different type of textiles. The silver (Ag) and zinc oxide (ZnO) are the most popular materials in order to improve antibacterial properties of textiles. The purpose of this paper is to investigate the possibility to produce Ag nanoparticle (NP), ZnO NP, Ag/ZnO NP composite materials in this experimental study.

It was investigated whether it was possible to produce Ag NP, ZnO NP, Ag/ZnO NP composite materials by hydrothermal method which was known as in-situ approach on the fiber. In addition, the colloidal silver (Ag+) was produced by electrolysis method, and used instead of process water which was necessary during generating of NPs on the fiber by this method. After whole applications, the samples were characterized by SEM, XRD, EDX analyses and the antibacterial activity of specimens was tested according to the ASTM E 2149-01 (gram-negative Escherichia coli). In addition, the resistance to the repeated washes of these antibacterial samples was investigated.

The production of NPs on the fiber was achieved. The results showed that the samples had sufficient antibacterial activity and this activity did not reduce depending on repeated washing treatments.

Because of usage of one type of fiber, it would be necessary to make researches on the different type of fiber, testing procedure (with different bacteria), washing replications and prescriptions.

During the process the temperature control is very important for the produced fiber. In addition chosen antibacterial test method is crucial for the testing of activity of product. Fiber must be washed at least once to remove unfixed NPs on the fiber.

The technical antibacterial polyester fiber was in-situ coated by hydrothermal method with Ag, ZnO, Ag/ZnO composite NPs.
