Knitted fabrics (Figure 12) are created by intermeshing loops of yarns using knitting needles (Leong et al., ).Depending on the direction in which the loops are formed, knitted fabrics may be broadly categorized into two types—warp knitted fabrics (Figure 12(a)) and weft knitted fabrics (Figure 12(b)).By controlling the loop (stitch) geometry and density, a wide variety of knitted.
Modern knitted fabrics cover a wide range of structures; therefore this chapter is confined to a generalised summary of weft knitted fabrics. It explains why knitted fabrics stretch more easily than woven fabrics made from similar materials and compares the dimensional ability, creasing production and properties of weft-knitted fabrics.

Weft Knitting Manufacture. Weft knitting is a knitted piece of fabric where the stitches run from left to right horizontally across the fabric.
It is usually knitted with one piece of yarn, and can be made either by hand or using a knitting machine. The properties and performance characteristics of yarns and fabrics are evaluated, including hairiness, diameter, evenness, tensile properties, and.
Weft knitted fabrics may be approximately divided into single or double jersey ('double-knit') according to whether they were knitted with one or two sets of needles. It may be preferable to include some of these fabrics in separate groupings of underwear and speciality fabrics.
Pelerine eyelet, sinker wheel mesh structures, and float plated fabrics are mainly used for underwear. Properties of honeycomb polyester knitted fabrics A Production and properties of weft-knitted fabrics. book Feng. Hebei University of Science and Technology, Shijiazhuang, Hebei, China.
E-mail: [email protected] Abstract. The properties of honeycomb polyester weft-knitted fabrics were studied to understand their advantages. Seven honeycomb polyester weft-knitted fabrics and one commonAuthor: A F Feng. The process involves the use of two pairs of needles set at an angle to each other.
Fibers that the generally used to make double knits are polyester and wool. Double knits are weft knitted fabrics made with two production and properties of weft-knitted fabrics. book of needle beds. The fabric structure is more stable and compact.
The fabrics do not curl at the edges and do not : Textile School. the end use of compact yarn is becoming more and more important due to its special characteristics.
Therefore, there is a need for assessing the quality of the knitted fabric produced from the compact yarn. In the case of weft knitting, the dimensional properties of stable weft knitted fabrics depend mainly.
Elasticity of the warp knitted fabrics is less than weft knitting. Elasticity of the weft knitted fabrics is higher than warp knitting. Its shrinkage properties is less.
Its shrinkage properties is higher than warp knitted fabrics. Here courses are needed for each pattern row.
Courses are equal to the pattern. Yarns are supplied from beam. Weft-knit and warp-knit fabric. There are two basic varieties of knit fabric: weft-knit and warp-knit fabric.
Warp-knitted fabrics such as tricot and milanese are resistant to runs, and are commonly used in lingerie. Weft-knit fabrics are easier to make and more common. Production of Knitted Strain Sensing Fabrics. A single design of knitted strain-sensing fabric was devised and three different variations of the basic knitted sensor were created using decitex (the mass in gram of 10, m production and properties of weft-knitted fabrics.
book yarn), decitex double covered elastomeric yarns and silver coated nylon by: properties, since loop length variations lead to the production of knitted fabrics with different properties from place to place. The third method is widely used in flat knitting for the production of fully-fashioned pieces.
Two operations can be performed: increasing and decreasing the number of operating needles (widening and narrowing). Weft knitted fabrics: A horizontal row of loops can be made using one thread runs in horizontal direction.
The fabric structure is different from one from another. Weft knitted fabrics are widely use. In our daily life, we use different knitted fabrics. Depending on the fabrics design knitted fabrics can be as follow: Single Jersey; Plain. In this work, the effect of yarn production techniques on the physical properties of basic weft knitted fabrics has been studied.
The fabrics knitted from ring combed and compact yarns were used for the study and comparison. 2 Materials and. The dimensional properties of single jersey weft knitted fabrics made from tex viscose, modal and lyocell spun yarns with three different loop lengths has been investigated under three different conditions such as dry, wet and fully relaxation.
The process of dry, wet and fully relaxation for a knitted fabric involves change in the internal. This chapter details the most important development steps, binding elements, and basic bindings of weft knitting as well as the basic properties of weft knitted fabrics.
This overview will include the various ways of influencing the properties of a mechanical engineering-based production of Cited by: 1. Generally, a set number of yarns are used for the formation of fabrics. Also, a number of techniques are used for producing fabrics such as weaving, knitting, and felting.
The type of fabrics varies by the fibers, the fabric formation techniques, machinery used for producing them, and finishing techniques. Fabrics also made differently based on the : Textile School.
Weft knit reinforcement fabrics When “warp” and “weft” yarns cross at degree angles, the result is common cloth. But when small yarn loops reinforce each of those intersections, the result is a weft knit reinforcement fabric of uncommon strength and.

Knit fabric production is easier and quicker than weaving technique. Though knitting production is simple, its technical parameters calculation is complicated and difficult than weaving. Technical parameters involved in the knit fabrics are: loop structure, loop/stitch length, CPI,WPI, GSM, shrinkage, spirality, fabric width etc.

Department of Textile Science and Technology Ahmadu Bello Unversity, Zaria, Nigeria Abstract Different types of acrylic yarns such as twisted spun acrylic yarn 3-ply (Sample A), relaxed ring spun acrylic.
The influence of preform stretching on mechanical properties of weft knitted PP/glass fibre composites was estimated. Stretching of Rib weft knitted fabric was performed prior to consolidation in a wale or course direction and biaxially.
Preform stretching increased tensile and bending strength of composite as a result of additional orientation of the reinforcing Cited by: 8.
For production of thermoregulatory knitted fabrics we usually use a special fibre called ThermoLite. The technology of hollow fibre provides the best insulation properties. The micro-structure of hollow fibres contains air heated by body temperature and thus it provides excellent thermoregulation at very low surface mass of knitted wear.
properties of a plain weft-knitted fabric and of polymer composite materials reinforced by it. Cotton yarn and fabrics are being considered as an environmentally friendly alternative to synthetic reinforcement in polymer composites.
In the present investigation, cotton yarn of different length. This book provides an updated reference to Knitting technology, with specific focus on the developments in knitted fabric production and textile applications.
The first set of chapters begin with a brief review of the fundamental principles of knitting, including the types and suitability of yarns for knitting as well as the properties achieved.
knitted fabrics, more special with respect to their characteristics, production and applications. Knitted fabrics can be produced at high rates and for low costs. These fabrics are popular for apparel and garments due to their shape fitting properties softer handle bulkier nature and high extension at low tension.
, File Size: KB. Rib Pointelle Classification of Knitted Fabrics Definition after ISO Knitted fabrics are made from interlocking loops, formed from a single yarn or from many. They are classified into weft knitted and warp knitted fabrics. Characteristics Characteristics May be made from a single yarn.
Requires a full warp sheet. Knitting. Knitting is the second most popular technique of fabric or garment formation by inter-looping one or one set of yarns. Continuous length of yarn is converted into vertically intermeshed loops either by hand or by machine.
The most important parameter of a knitted fabric is loop length which can be varied during knitting by changing machine. The aim of this study is to investigate the water (moisture vapor and liquid) transfer properties of two‐layer weft knitted fabric and some related factors.
Some experimental fabrics with specific yarns and stitch densities were prepared. Water vapor permeability rate through the fabrics and liquid water transfer from inner to outer layers were measured. The results show that the. Biaxial weft knitted (BWK) fabrics include weft and warp yarn layers, which are held together by a stitching yarn system.
Reinforcing yarns, such as glass or aramid fibers, can be used within all yarn systems. The strength and the stiffness of composite can be improved by reinforcing yarns . Knitted fabrics have an orientation of yarns not Cited by: 4.

Weft and warp knitting are completely different knitting techniques that result in two different types of fabrics.
The most obvious difference in these two techniques is that weft is a yarn that runs back and forth, while warp is a yarn that runs up and down.
Flat Knitting Technology. INTRODUCTION: The fabric which is produced by the machine is usually weft knitted fabric. Flat fabric will be produced.
In the flat knitting machine needles are kept stationary and the cam will move along the width of the machine (vice versa to circular knitting machine). It was first invented in TYPES OF MACHINES. WARP KNIT FABRICS. A FABRIC MADE BY WARP KNITTING Warp knitting is a family of knitting methods in which the yarn zigzags along the length of the fabric, i.e., following adjacent columns ("wales") of knitting, rather than a single row ("course").
Since warp knitting requires that the number of separate strands of yarn ("ends") equals the.
