Fabric properties are the characteristics of a specific fabric. Physical properties of ring, compact, and air vortex yarns made of PTT/wool/modal and wearing comfort of their knitted fabrics … The drape coefficient (F) is the most fundamental parameter for quantifying drape and the most widely used for textile materials. Cross miss structures have high length-wise shrinkage than single pique and single jersey. Dear Twitpic Community - thank you for all the wonderful photos you have taken over the years. A tuck stitch is composed of a held loop, one or more tuck loops, and knitted loops. These properties are determined by raw material types and characteristics, knitting machine parameters, and type of knit structures. The cotton yarn made out fibers that had Fiber bundle tenacity of 28.78 cN/tex, upper half mean length of 2.69 cm, uniformity index of 81.5, micronaire of 4.09 and short fiber content (%) by weight of 11.69 was used in the study. In all structures, the largest percentage of shrinkage was observed length-wise. Since the construction of knitted fabrics makes them able to be used in smaller... 3. The quality is important to MASCOT, and because of this we only uses the best fabrics from among others TENCEL®, COOLMAX®, CORDURA® etc. The main aim of this research is to investigate physical properties (thickness, tensile strength, abrasion resistance, bending stiffness and rigidity) of novel CWK fabrics designed for use in clothing. This test was carried out according to ISO3801. Before measuring to relieve localized stresses caused by handling during preparation, the samples were conditioned. The N95 mask -- and its sisters and brothers -- is best fitted to a person's unique facial contours on a bare face to keep the seal tight. In general, after washing the length of knitted loops become smaller or larger and the fabric will shrink positively or negatively in the width and length direction. Sometimes yarn overlapping caused release in course-wise and shrinkage in wale-wise. Finally, the samples were dried using mini drying machine and shrinkage percentage calculated using the following formula. This is due to the fact that, tuck loops reduce fabric length and length-wise elasticity because of the higher yarn tension on the tuck and held loops that cause them to rob yarn from adjacent knitted loops, making them smaller. Fabric bending behavior has been the focus of many investigations. It was found that the presence of a tuck stitch in a given structure increases air permeability, areal density, width-wise extensibility and length-wise shrinkage. This provides greater fabric stability and less flexibility than single jersey and single pique structures. When yarn count increases Spirality increases and vice versa.9 In addition to other knitting and yarn parameters, the effect of stitch type has an influence on the bursting strength of knitted fabrics. Moreover, there was a considerable amount of change within the structure. Significantly high colour difference values were obtained for cotton (from 7.9 to 14.2) and cotton/polyester (from 8.5 to 14.4) knitted fabrics. Don’t form runs. ASTM D42261 1.5 lbs. A held loop can only be retained for some knitting cycles. [11] Kim, H. A. There are three diameters of spacemen (24 cm for limp fabric, 30 cm for medium fabric and 36 cm for stiff fabric) that can be used. Fabrics which are in common commercial use in the textile industry were selected, and they are used as clothing fabrics. A tuck stitch contains a held loop, more tuck loops and knitted loops. Snagging is the formation of yarn pulls on the surface of a fabric. However, for this study only fabric structures were considered. The length of knitted loops becomes smaller or larger and the fabric shrinks positively or negatively in the width and length direction. Fabric cost and cut-and-sew labor are the two largest expenses in apparel manufacturing 2.Raw materials represent 50 to 70 percent of the total product cost 3, but compromises in quality and quantity of fabric directly influences the quality of a final product.Instead, the viable solution to … Knitting technology: a comprehensive handbook and practical guide. Tear Strength is the meaurement of stress exerted to rip the fabric under tension. It is observed over a decade that consumers prefer to wear lightweight fabrics. Figure 6. The vertical rows of loops are called ribs or wales, and horizontal rows of loops are called courses. The modeling studies to explain mechanical properties of TRPCs have been investigated. Due to these reasons, cross miss structure shows higher GSM value than single jersey structures. This leaves other textile structures, such as knitted, braided, and nonwovens, understudied. The most important use of wool is for apparel coats, jackets, suits, dresses, skirts, slacks made from woven fabrics of varying weights and knitted fabrics’. The main reason for the high colour difference results was the alteration in the structure of the knitted fabrics. Fabrics used for this study were selected based on common commercial use in the textile industry, and they are common in clothing fabrics and are commercially available.
