  • Woven Fabrics
    Fabric – Woven Fabrics WOVEN FABRICS Fabrics are made of yarns by weaving them in different combinations. It is mostly done by interlacing two sets of yarn or thread made of fibers called the warp and weft of the loom. It only stretches in the bias directions, between the warp and weft directions, unless the threads are elastic. Lengthwise stronger vertical yarns with more twist are Warp or Picks while widthwise filling yarns are termed as weft or ends. Sidewise edge of fabric is termed as Selvedge. THREE BASIC WEAVES There are three main types of weave: Plain, Twill and Satin Plain weave is a basic weave which is made when the thread is woven on one up and one down principle, some plain weave fabrics are Chambray, Chiffon, Gingham, and Organza etc. Twill weave is made when the thread is placed by varying the order of interlacing the yarns so that diagonal parallel lines are produced across the fabric. Satin Weave is a weave made when each warp yarn floats over four filling yarns and interlaces with fifth filling yarn. Plain weave Twill weave Satin weave Fabric – Weft Knit Fabrics Knitted Fabrics Knitting is the process of construction of a fabric by interlocking loops of yarn by means of hooked needles. Knitted fabric consists of horizontal rows known as courses and vertical columns of loops known as Wales. Knitted fabrics are porous having insulated air pockets giving warmth when worn. Knitted fabrics are very absorbent, wrinkle resistant and lightweight. They shrink more than woven fabrics unless shrink- proofing techniques are used.

  • Effect of Padder Roller Speed and Pressure During Pre-Treatment on Color Characteristics of Digitally Printed Cotton Knit Fabric Grace Wasike Namwamba and Devona L
    Effect of Padder Roller Speed and Pressure during Pre-treatment on Color Characteristics of Digitally Printed Cotton Knit Fabric Grace Wasike Namwamba and Devona L. Dixon, Textile Technology Southern University Agricultural Research and Extension Center, Baton Rouge, LA 70813 ABSTRACT The purpose of this study was to determine the effect of padder roller speed (RPM) and pressure (PSI) on the color of digitally printed cotton fabrics. Single layers of double-knit cotton fabric were padded at speeds of 20, 40, and 60 rpm and pressure levels of 5, 15, 40, 60, and 70 psi using a 36” wide padder. The padding solution consisted of alginate, soda ash, urea, and distilled water. Color readings were taken using a spectrophotometer. Results indicated that roller speed and roller pressure both had an effect on the shade depth of the fabric. The deepest color depth was obtained at a roller speed of 40 rpm and roller pressure of 20 psi. INTRODUCTION Printing directly onto a substrate requires the fabric be chemically pre-treated to ensure optimum dye penetration and color vibrancy. The padding solution or chemical pre-treatment may vary according to fiber chemistry and end-use requirements. Common pre-treatment solutions for digital textile printing of cotton (cellulosic) fibers include a mixture of alginate, soda ash, urea, and distilled water where alginate and urea are the thickeners for the pre- treatment solution. In this formulation, alginate is mixed with urea to control the temporary containment of droplets spreading toward the fabric (Baffoun, Viallier, Dupuis, & Haidara, 2005). The chemical pre-treatment is best applied using a padder (Namwamba, 2005) consisting of rollers.

  • Proper Processing of 100% Cotton Knit Fabrics
    TECHNICAL BULLETIN 6399 Weston Parkway, Cary, North Carolina, 27513 • Telephone (919) 678-2220 ───────────────────────────────────────────────────────────────────── TRI 3011 WET PROCESSING OF 100% COTTON KNITTED FABRICS © 1999 Cotton Incorporated. All rights reserved; America’s Cotton Producers and Importers. INTRODUCTION It is well established that knitted fabrics of all constructions and fiber blends are inherently more prone to shrinkage as compared to wovens. Because of the inability of a knitter to form a knitted fabric with no shrinkage, it is important for the dyer and finisher to make an effort to remove as much shrinkage from the product as possible. However, the ease with which a cotton knitted fabric is distorted during processing makes it especially difficult to deliver fabrics with no shrinkage. This bulletin will discuss in some detail the aspects of knitted fabric construction and wet processing and how they are related in terms of shrinkage. The factors that influence the level of dimensional stability can be summarized as follows: © knitting parameters, © processing tensions after knitting, © relaxation techniques in finishing, and © mechanical and chemical finishes. Each of these areas can be broken down into fundamental aspects. KNITTING As published in literature, the amount of shrinkage for any given knit fabric is primarily dependent upon the product specifications and the knitting parameters used to meet those specifications. The predominant fabric specifications that determine the shrinkage of a knitted fabric are the weight, stitch counts, and width at which the fabric is sold for cut-and-sew. The knitter uses those specifications to establish another set of specifications for knitting. Whether or not these knitting specifications are achievable is determined by the knitting machinery available to the knitter.

  • Performance Evaluation of Knitted and Stitched Textile Strain Sensors
    sensors Review Performance Evaluation of Knitted and Stitched Textile Strain Sensors Kaspar M.B. Jansen Emerging Materials Group, Department Industrial Design Engineering, Delft University of Technology, 2628 DE Delft, The Netherlands; [email protected] Received: 22 October 2020; Accepted: 15 December 2020; Published: 17 December 2020 Abstract: By embedding conductive yarns in, or onto, knitted textile fabrics, simple but robust stretch sensor garments can be manufactured. In that way resistance based sensors can be fully integrated in textiles without compromising wearing comfort, stretchiness, washability, and ease of use in daily life. The many studies on such textile strain sensors that have been published in recent years show that these sensors work in principle, but closer inspection reveals that many of them still have severe practical limitations like a too narrow working range, lack of sensitivity, and undesired time-dependent and hysteresis effects. For those that intend to use this technology it is difficult to determine which manufacturing parameters, shape, stitch type, and materials to apply to realize a functional sensor for a given application. This paper therefore aims to serve as a guideline for the fashion designers, electronic engineers, textile researchers, movement scientists, and human–computer interaction specialists planning to create stretch sensor garments. The paper is limited to textile based sensors that can be constructed using commercially available conductive yarns and existing knitting and embroidery equipment. Within this subtopic, relevant literature is discussed, and a detailed quantitative comparison is provided focusing on sensor characteristics like the gauge factor, working range, and hysteresis. Keywords: textile strain sensors; conductive yarns; knitted sensor; stitched sensor; performance evaluation 1.

  • Coated Textile Materials
    13 Coated Textile Materials Stana Kovačević, Darko Ujević and Snježana Brnada University of Zagreb Faculty of Textile Technology Department of Textile Design and Management *Department of Clothing Technology Baruna Filipovića 28a, 10000 Zagreb, Croatia 1. Introduction Top finishes began to be used already in the 18th century when fabrics were coated with linseed oil to produce oilcloth. This was the first procedure of coating several agents to the textile substrate and can be considered as the predecessor of multi-layered materials. Textile surface materials coated with chemical l structures have been developed continuously for several last decades. The basic substrate of the surface material is mostly textile fabric coated on one or both sides with one or more polymer layers. This kind of products with the basic textile material has many improved properties and multiple advantages over the classic textile material [1 - 3]. Polymer layers can be polyurethane, polyvinylchloride or polyacrylate layers. To improve their properties, appropriate additives are added: softeners, porosity-generating agents, filling materials, binders, fungicides etc. Coated polymers are applied to the textile material directly, and indirectly using paper or coagulation procedure. The constant development of the coating technique resulted in the newest achievements the result of which is the application of nanoporous polymers to the textile substrate. The use of these products is increasing and they are gaining greater importance in the clothing industry. They are especially widespread in the protective clothing where they meet all the market requirements. The design of a multilayered material is based on a target product so that it is very easy to obtain a material with desirable properties.
