Usage: Garment Material: Bamboo/Spandex Style: Printed Technics: Weft Knitting Pattern: Anchor Width: 58/60". This lesson is the first in our 7-part series on working with knit fabrics. We start by demonstrating the difference between woven and knit fabrics and then how knits are structured. You will learn the meaning of terms like knit and purl, wale and course and how a weft knit differs from a warp knit. We will teach you about how knits are made and about the different types of yarns, so that when.
Read article about The fabric structure is the fundamental unit that controls all properties of weft knitted fabrics. S Senthil Kumar discusses derivatives of structures in weft knitted fabrics. 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 flexibility for critical reinforcement needs.

Materials and Manufacturing Processes: Vol. 23, No. 7, pp. Textile - Textile - Production of fabric: Fabric construction involves the conversion of yarns, and sometimes fibres, into a fabric having characteristics determined by the materials and methods employed. Most fabrics are presently produced by some method of interlacing, such as weaving or knitting. Weaving, currently the major method of fabric production, includes the basic weaves, plain .

1. Quality control in the knitting process velu EiTEX, BDU. 1 2. • Knitted fabric is gaining popularity in the textile and clothing industry. The demand for knitted fabrics is increasing: consumers today are looking for comfort, fashion and style, which results in ever- changing demands on the apparel market.
2 3. Single-jersey fabric is a weft knitted fabric made on one set of needles. Double-jersey fabric is a weft knitted fabric made on two sets of needles, usually based on rib or interlock gaiting, in a manner that reduces the natural extensibility of the knitted structure.
These fabrics can be non-jacquard or jacquard. Course is a row of loops across the width of the by: 8. Weft knitting. The type of stitch used in weft knitting affects both the appearance and properties of the knitted fabric.
The basic stitches are plain, or jersey; rib; and purl. In the plain stitch, each loop is drawn through others to the same side of the the rib stitch, loops of the same course are drawn to both sides of the web is formed by two sets of needles, arranged.

So quality control is very important for all types of. Kalayu, G., Identifying defect causes of weft greige knitted fabric: the Case of MAA-Garment & Textiles Factory. Mekelle University. Knitting technology: a comprehensive handbook and. Double Knit Fabric. Double Knits are made from the interlock stitches and its variations.
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 sets of needle beds. It is very difficult to maintain& control circular knitted fabric parameters due to severalvariables (like yarn type, yarn quality, yarn twist, fabric structure, machine speed, machine rotation, yarn tension, take up tension & many more) related with circular knitting production and influences of them are unavoidable, so the parameters can be.
It is well known that weft knitted fabrics tend to undergo large changes in dimensions and are often and aware of fabric quality and expect higher standards of performance than ever before, even after a Determination of fabric dimensions and properties; denotations and units 1.

It is usually knitted with one piece of yarn, and can be made either by hand or using a knitting machine. Weft knitting is the most common form of knitting as it is simpler than warp knitting, the other. The term knitwear includes two main textile techniques, weft and warp knitting (Spencer, ; Weber and Weber, ) (Table ).
After weaving, it is the most common method of manufacturing textile fabrics. Because of the interlooped structure of the knitted fabric, the properties are completely different to woven fabrics. The 3D models of plain weft knitted fabrics can be generated by sweeping the circular cross- section of the yarn along the central axis of the yarn.
Yarns were assumed to be incompressible in nature. Figure Macrostructures of plain weft knitted fabrics [F1] Figure Macrostructures of plain weft knitted fabrics [F2]. Knitted fabrics tend to change dimension in width and length after being taken off the machine even without yarn shrinkage indicating a change of loop shape rather than of loop length.

Most weft knitted fabric in continuous lengths s knitted on large-diameter, multi-feeder, latch needle machines and is slit into open width druing finishing. The emphasis is on productive efficiency and quality-control in the manufacture, finishing, and conversion of fabric.
12 Handmade knit fabric. Knitting is a hobby to countless men and women all across the world. With the help of knitting needles and yarn and countless hours of patient hand labour beautiful fabric is knitted and made into clothes – more beautiful than any machine can conjure up – because of the love and effort that goes into each piece.
In weaving it needs warp and weft yarn for produce woven fabric but in knitting, fabrics are produced from a series of yarn in warp or weft directions.
Knitting techniques can be defined as follow. The processes in which fabrics are produced by set of connect loops from a series of yarns in warp or weft direction is defined as knitting. Fabrics with specified dimension are handled in water of a certain temperature in a certain time; then measure the length change in the warp and weft direction after fabrics are dried and evaluate shrinkage of fabrics.
Mechanical Shrinkage Method usually adopts shrinkage tester to complete the test, and it is divided into two types: cylinder.
An analysis of experimental data on plain knitted fabric dimensions reveals that the area (Ks) and linear (Kc, Kw) parameters are not tenable propositions, at least for rotor spun cotton yarns. The gross dimension of knitted fabric is simply a reflection of any shape & size of individual loops.
There are several key variables in the production which affect the average shape & size of the loops. After knitting the grey fabric is dyed to required shade & finished to .Circular knit fabrics A knitting process that links circular stitches in a continuous chain yields uncommon strength and form-fitting ability for a variety of uses.
By alternating between single- and double-knit processes, Highland can vary the style, width and weight of the fabric to your exact needs.Weft knitting is "a common type of knitting in which one continuous thread (yarn) runs crosswise in the fabric making all of the loops in one course.
Weft knitting types are circular and flat knitting." In circular knitting, "the fabric is produced on the knitting machine in the form of a tube, the threads running continuously around the fabric.".
