Abstract:

It is known that the saw cylinder is the main working organ in the cotton ginning process. The process of ginning occurs as a result of the cotton raw materials entering the gin roll box and meeting the rotating saw teeth. In the roll box, the cotton raw material rotates like a gin saw, forming a mass roller consisting of fully depilated and partially depilated seeds. The density of this mass shaft increases towards the center of the roll box. As a result, due to the formation of a crack between the roll box and the ribs, the depilated seeds move downward under the influence of their weight an

Abstract:

Today, environmental problems are increasing rapidly and the focus is shifting to seeking long-term and sustainable solutions. At this point, the economical use of raw material resources is important and this makes recycling a necessity, not a diversity. In this context, environmentally friendly acoustic panels are designed with composites produced by recycling 100% textile and packaging wastes for the noise problem in buildings. Denim fabrics from textile wastes and low-density polyethylene bottle caps from packaging wastes are used. Denim fabrics that are shredded into cotton fibers are blen

Abstract:

The contamination of natural fiber yarns with polymeric fibrils is a common problem in the textile industry. This work demonstrates that near-infrared spectroscopy in the 2250 to 2400 nm region is a viable technique for the detection of hydrocarbon-based polymeric contamination in both wool and cotton yarn samples. Both high-density polyethylene and polypropylene fibrils typical in size to those found in industry could be detected irrespective of polymer and yarn color. A principal component analysis model based on first-order derivative spectra was developed in which yarns contaminated with p

Textile dust released from hospital textiles is a considerable food source for pathogenic microorganisms and can lead to infections and illness in patients and medical staff. In addition, it often causes malfunctions in sophisticated medical equipment. The structural parameters of the fabric, such as the raw material composition, the thread density and the fabric weave, can influence the amount of dust produced. Friction between threads in a woven fabric plays a crucial role in dust generation, and friction is influenced by the surface structure of fibres, yarns and fabric. Understanding these
