Quality is the most perspective demand in the produced textile fabrics which mainly viable by two factors one is fabric properties and other fabric defects. We have done our experimental part with some process controlling data for six knit fabrics and we got shrinkage is the most problem of finishing process. Little about Fabrics: Textile fabrics are available in three main categories - knitted, woven and non-woven fabrics. Fabrics are manufactured in textile mills, and power looms sectors. Later, greige fabrics are finished as per the buyer’s (garment manufacturers) requirement. For example, one piece 60 yards long would be allowed to have six defects. Another system for evaluating piece goods is the Four-Point System. In this system, you should inspect at least

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.

Knitted fabric defects by Hailay 1. Hailay kidane,wollo university,[email protected] 2. defect of the knitted fabric A defect of the knitted fabric is an abnormality which spoils the aesthetics i.e. the clean & uniform appearance of the fabric & effects the performance parameters, like; dimensional stability etc.
A defect of the knitted fabric is an abnormality which spoils the aesthetics. 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.

Identification of knitted fabric defects: It is very natural that in the course of knitting fabrics, imperfections occur. The imperfections may be the result of faulty yarn, knitting machine. Textile - Textile - Dyeing and printing: Dyeing and printing are processes employed in the conversion of raw textile fibres into finished goods that add much to the appearance of textile fabrics.
Most forms of textile materials can be dyed at almost any stage. Quality woollen goods are frequently dyed in the form of loose fibre, but top dyeing or cheese dyeing is favoured in treating worsteds.
The causes of these defects are enlisted below: 1. Flushing/Wicking: Caused due to Low viscosity of print paste. It occurs when the printed area bleeds out into the unprinted area. The result is a haloing or shadowing effect around the outline of the pattern design.

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. The aim of this book is to provide the background of the warp knitting patterning with a large amount of simulated 3D images of the structures, corresponding to the modern available tools for this.
The warp knitted structures can have very complex architectures and very limited understanding exists. INTRO TO FABRIC CATEGORIES WEFT VS WARP KNITS SINGLE KNITS DOUBLE KNITS TRICOT KNITS RASCHEL.
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.
The fabrics which are produced by interlacing one set of yarn are known as knit of knitted fabric. It should be noted here that, knit fabric and knitted fabric are same. #N#Fig: Knit fabric.

Woven fabrics are made by using two or more sets of yarn interlaced at right angles to each other. Knitted Fabric Knitted fabrics are formed by series of interlocking loops (example: knit wears) Sewing Thread 1. Sewing Thread is a type of yarn used for sewing. Various types of fabric. Bow or skew can be induced during fabric manufacturing, dyeing, tentering, finishing, or other operations where a potential exists for uneven distribution of tensions across the fabric width.
Bow and skew are more visually displeasing in colored, patterned fabrics such as plaids and horizontal stripes rather than in solid colors because the contrast makes the distortion more prominent.
fashion, later knitted pullovers, cardigans, skirts, men's underwear, sportswear and swimwear became popular. Developments in the 20th century increased the production speeds of the machines and offered wider choice to pattern the knitted fabrics.

Defects which are not desirable and are clearly detectable on the inspection frame will be assigned points as shown in the Four Point Table.
The Four Point system will be applied to all fabrics, i.e. woven, circular knit and warp knit.

Now textile engineering study is becoming more demand-able then before.The finished fabric may involve raw material irregularities that may become more apparent after dyeing and finishing. It also includes yarn defects like thick and thin places.
In addition weaving or knitting imperfections occur, such as miss picks, broken ends, and miss stitches.
