Seams are basic requirements in the manufacturing of garments. In general, seam performance has a great influence on the garment quality. Seam and stitch types affect the quality and appearance of garments. Seams of the garment must be durable and smooth. Stitch and seam types and stitch and seam parameters should be selected according to the garment and fabric : Ayca Gurarda. Mainly two types of knitted fabrics are produced. They are as follow: Warp knitted fabrics: In a warp knitted structure, each loop in the horizontal direction is made from different thread and the number of thread used to produce such a fabric is at least equal to the numbers of loops in horizontal row.

In Part II the first model is presented, a 3D model based on the classic elastica theory, and it is used to calculate the load-extension curves of a plain weft-knitted fabric in coursewise and walewise directions. Good agreement is obtained between Cited by:
Fabric properties are the characteristics of a specific fabric. Properties of woven fabrics are very different to properties of knitted fabrics. Build up your knowledge of these properties, to ensure that you always choose the right textile for your project. Range of % waterproof & water resistant fabric. Made using protective coatings. ASTM's textile standards provide the specifications and test methods for the physical, mechanical, and chemical properties of textiles, fabrics, and cloths, as well as the natural and artificial fibers that constitute them. The textiles covered by these standards are commonly formed by weaving, knitting, or spinning together fibers such as.

Two knitted fabrics can be joined by embroidery-based grafting methods, most commonly the Kitchener stitch. New wales can be begun from any of the edges of a knitted fabric; this is known as picking up stitches and is the basis for entrelac, in which the wales run perpendicular to one another in a checkerboard pattern.
Knitted fabrics can be made much more quickly and easily than woven fabrics at comparatively less cost. Two yarns forming loops in each course of the fabric knit the fabric. Knitting machines form loops of yarn with many pointed needles or : Textile School.
Knitted fabrics and their properties 1. Chapter 9 Knitted Fabrics and Their Properties Knit fragments dating back to BC Compared to 9, years for wovens Introduced to Europe Extension properties of seams in knitted fabrics book the Arabs Did not gain popularity until around 1, AD 2.
The extension meter 61 measures the extensibility of the fabric at three loads, 5 gf/cm ( N/m), 20 gf/cm ( N/m) and gf/cm ( N/m) in the warp and weft direction to indicate potential problems in the laying up of the fabric and in seams that require overfeed.
This information is also combined with the bending rigidity to determine the fabric ‘formability’ which is a measure of. Blackwood and Chamberlain () compared the extension properties of ISOand seams on knitted fabrics. ISO seams observed maximum extensibility, whereas ISO and seams provided 80% extensibility.
Extensibility of seam is influenced by Cited by: 4. derivative knitted fabrics and 1×1 rib knitted fabrics of glass fibers have been compared. The paper in  shows that the weft knitted fabrics with Rib structure have a superior tenacity.
In order to analyze the break ing properties of the seams made on the knitted fabrics, 2 types of elastic stitches, with different values of the distance between stitches will be tested.

Jersey fabrics: Their production and properties: an introduction to single jersey and double jersey weft knitted fabrics and to tricot and Raschel warp Author: K. D Darlington. Different parts of fabrics are attached together using several processes such as fusion, gluing, sewing, stapling, etc.
Seam can also be defined as the application of a series of stitches to hold several thicknesses of materials. Factors of Seam Properties: The following are the factors of which seam properties depends on. This study attempts to better understand the seam grinning behavior of four thread overlock seams (stitch type ISOseam type Ssa-1, superimposing two plies of material) on knitted fabrics under the influence of repeated extension and by: 6.
of the mechanical behaviour of weft-knitted fabrics and weft-knitted reinforced composites made of glass fibre. The objective is to find ways of improving the mechanical properties and simulating the mechanical behaviour of knitted fabrics and knitted reinforced composites, so that the engineering design of such materials and structures may be.
ted fabrics make them desirable for many purposes. They will stretch un- der tension and recover their dimen- sions to a considerable extent when tensions are released. Knitted garments conform to the shape of the body and are comfortable to wear.
Knitted fabrics are more absorbent and warmer than woven fabrics of comparable weight. as the knitted loops leave the needles the spacing of courses and wales decrease and the fabric shrinks in both directions thus affecting the properties of knitted fabric.
The aim of this research was to study the effect of Lycra extension percent on the properties of the. Clothing is the most popular item to make with knits because of the many varieties of knit fabrics available.
Use jersey, which is a single knit, to make clothing with a soft, fluid design, suggests Claire Shaeffer in her book "Claire Shaeffer's Fabric Sewing Guide," such as dresses, T-shirts, soft jackets and coats.

The dimensional and physical Properties of Cotton/elastane single jersey fabrics varies as compared with fabrics knitted from % cotton yarn. The object of this study is to investigate how it varies when the fabrics are made from % cotton yarn and cotton/elastane blended yarns & also to study the effect of elastane on the basic principle physical properties like GSM, Air Permeability.
In order to examine the mechanisms by which seams age and fail under loads typical of those in use, factors and interactions among factors influencing the change in load required to extend an ISO stitched seam (type ISO ) during repeated lon gitudinal extension/recovery cycles Cited by: Roobeedoo assurred me that I could really trim that seam back, as knit fabrics don’t unravel.
I took her at her word. I bought some Lite Steam-A-Seam from Amazon. Deb said she used this product on her seams when sewing with knit fabrics. Out of sheer curiosity, I ordered some.
It really helped to stabilize my seams, without being too stiff.

Where one is made up of woven wefts and warps, the other is made by looping them. This difference in construction gives both fabric types completely different characteristics.

The yarns used were a 30% Outlast®Viscose / 70% Cotton, tex and a Dacron WSD /38, tex (Coolmax®). The plating yarn was a 44 dtex bare elastane from Creora, plated at every feeder.This paper reports on an investigation of physical properties on some of the clothing comfort properties of knitted fabrics.
Fabric parameters such as fabric density, fabric thickness and fabric weight have been considered to be correlated to air and water vapor permeability, and also moisture management properties which includes accumulative one-way transport index and overall moisture Cited by: 1.
