Research Regarding the Influence of Raw Material and Woven Fabric Geometry on the Air Permeability of Mattress
Abstract Properties of woven fabrics are influenced by many factors: the nature of raw materials, woven fabric geometry and density, technological parameters of the weaving operation and finishing. The main purpose of this research paper is to increase the performance of woven process during mattress manufacturing by choosing the right woven fabric geometry and raw material. The variation in air permeability depends on the area density, linear density, loop length and thickness of yarns. To obtain woven fabric samples were used several types of classic yarns, also ecological yarns like organic cotton and bamboo viscose. On the other side, tests results show the fabric resistance regarding a…
Research Regarding Uniaxial Tensile Strength of Nylon Woven Fabrics, Coated and Uncoated with Silicone
Properties of woven fabrics used to make airbag cushions are influenced by a lot of factors: the nature of raw materials, woven fabric geometry and density, technological parameters of the weaving operation and finishing. The main purpose of this research paper is to find the values of three mechanical parameters – tensile strain, tensile stress and specific modulus – according to the type of samples and test direction on the testing stand. To obtain woven fabric samples were used polyamide 6-6 polyfilament yarns (nylon), silicone coated and uncoated fabric. Testing procedure and samples preparation were done following the standard EN ISO 13934-1:1999. Test results and graphs show that, we …
Research Regarding the Influence of Raw Material and Knitted Fabric Geometry on the Tensile Strength and Breaking Elongation
Abstract The main purpose of this research paper is to increase the performance of knitting process during socks manufacturing by choosing the right knitted fabric geometry and raw material. On the other side, tests results show the wear resistance regarding mechanical properties like tensile strength and breaking elongation of knitted fabrics for socks. To obtain samples knitted fabric were used several types of some classic yarns, which already use to obtain socks organic also another type of yarns less used: cotton, organic cotton, bamboo viscose, soy + cotton, Tencel. From these yarns the following knitted fabric geometry were obtained: plated single jersey, plated ribb 4:2 and plated p…
Study regarding the physical-mechanical properties of knits for garments – pilling performance
The effect of the pilling degradation results is an important decreasing in garment quality and a negative influence on the user’s comfort to wear. There are a lot factors, such as the yarn spinning system, fabric geometry and finishing operation, which affect the pilling performance. This research paper presents the investigation of fabric surface concerning pilling formation, especially knits, influenced by the fibrous composition. As samples were used knitted fabric panels, obtained from carded yarns, with fibers composition like cotton, wool or mixed one. Regarding fabric geometry 3 types were used – single jersey, 2x2 rib and moss stitch. In order to establish which of the yarns are mo…
Research Regarding the Physical-Mechanical Properties of Knits for Garments – Abrasion Resistance
Abstract During wear, the fabric is subjected to a complex combination of forces acting at various rates, in various intensities, in various directions and for various periods. This is one of the main causes of a fabric and garment becoming unacceptable for further wear. The main goal of this research paper is to improve the physical-mechanical properties of knits for garments by choosing the right fabric structure and raw material. The abrasion resistance is a mechanical deterioration and progressive loss of substance from a fabric, resulting from the fabric rubbing against itself or another surface. Tests was done on weft knitted fabric for garments using cotton, wool and mixed yarns, thr…
