Tightness factor of knitted fabric formula. Sitotaw43 and Sitotaw and Adamu44 studied the dimensional characteristics of five knitted fabric struc-tures made with 100% cotton and 95% cotton/5% elas-tane (EA). 5, for this experiment the above low tightness factors were Table I-Yam snarliness and main factors that in uenced knitted fabric porosity: cross-sectional area of each pore; depth of each pore or the thickness of the fabric; ( ) the number of pores per unit area or the number of courses and wales per unit area. 33–36 Tightness factor significantly influences the properties of knitted fabrics. In addition, it has also been deduced from the regression analysis that tightness factor can be used for fabric light permeability forecasting. e aim of this study is to use image analysis to assess the porosity of knitted fabrics produced on V-at-bed knitting Jun 30, 2022 · The paper aims at studying the effects of fabric aerial weight, thickness, tightness factor, and loop shape factor on thermal conductivity behavior of plain single jersey knitted fabrics made with Jun 1, 2016 · Generally the tightness factor of the knitted fabric is given [21] as follows: (14) Tightness Factor = tex L where L = loop length in mm. The interyarn pores will potentially be smaller in Aug 28, 2018 · Tightness factor indicates the looseness or tightness of knitted fabrics. INTRODUCTION . If the fabric has been knitted on a 30” diameter 30-gauge machine, find out the fabric width in meters. The functional properties of knitted fabrics are related to low stress mechanical properties, such as bending, shear, and tensile. Jun 1, 2016 · Generally the tightness factor of the knitted fabric is given [21] as follows: (14) Tightness Factor = tex L where L = loop length in mm. Oct 25, 2016 · The stitch length, tightness factor, and porosity affect the light permeability property of knitted fabrics. May 29, 2018 · Interlock knitted fabric made from 100% cotton is the tightest as compared to other fabrics made from 100% cotton and cotton/elastane yarns. Fabric tightness is recom- Tightness Factor With the perusal of the data (Table 2) it was noticed that the tightness factor of the knitted fabric increased with the increase in polyester content in the blends. Eltahan et al. It is also an indication of the relative looseness or tightness of the knitting (K = tex 1/2 l –1), where l is the stitch length. 5 but can be lower or higher depending on yarn count a rise in length of fabric knitted in unit time. Because, knitted fabric tightness factor formula is (√Tex/ stitch length in mm) and the yarn counts are 30 Ne for both 100 % CO and CO/SP yarns used. 03) for 100:0 blended fabric as compared to 0:100 blend which had the lowest value (13. Ans. 2 fabric, knitted from 30 Tex yarn to a loop length of 3 mm exhibits 180 courses /dm. It is calculated as the ratio of the area covered by yarn in one loop to the area occupied by that loop. The data indicated that tightness factor value was more (14. The study focuses on effect of twist multiplier on single jersey and 1 × 1 rib knitted fabrics loop length, loop shape, and tightness factors properties. 3 to 1. Fabric tightness is a parameter which shows the level of tightness in a knitted fabric. Fabric tightness is defined as the ratio of actual square fa-bric sett over the theoretical maximum square fabric sett for a defined weave and yam. the commonly used tightness· factors range between 1. 08) of tightness. Jan 1, 2023 · Tightness factor (TF) is a number that indicates the extent to which the area of a knitted fabric is covered by the yarn. Typical Tf values for plain knits range from 1. Therefore, tightness factor of these knitted fabrics is inversely proportionate to Apr 1, 2019 · The tests done for ten specimens and the results showed that loop length, loop shape, and tightness factors properties of single jersey and 1 × 1 rib knitted fabrics are significantly influenced Feb 1, 2008 · Tightness factor of those levels are calculated from the following formula [1 Weft knitted fabrics with 1×1 interlock structure were used as the preform for the composites. It is a similar kind of expression to that of cover factor of a woven fabric which indicates the relative openness or closeness of a knitted fabric. Tightness factor of fabric has examined by several researchers. Jun 1, 2016 · Generally the tightness factor of the knitted fabric is given [21] as follows: (14) Tightness Factor = tex L where L = loop length in mm. The goals of this study were to disclose the effect of 4×1 rib, 4×4 rib, half cardigan and full cardigan knit Structure on Dec 20, 2015 · Dimensional properties of knitted fabric or factors influencing knitted fabric quality: The factors on which the quality of knitted fabrics depends on: Courses per cm; Wales per cm; Stitch density per cm²; Shape factor (Wale spacing : Course spacing) Stitch density; Tightness factor K = √(tex/l) Area density Fabric tightness and cover factor are discussed. The tightness factor of knitted fabrics had a different influence due to the presence of 5% elastane yarns in the 95% cotton yarns. A higher Tf indicates a more compact and tighter knit. May 30, 2019 · The results disclosed that the fabric properties are greatly influenced by knit structures. The bending length and flexural rigidity was investigated in both wale and course direction. 41 and Eltahan42 deter-mined the SL, tightness factor and porosity of a single jersey knitted fabric using mathematical equa-tions. . It is well known that the tighter the knitted fabric, the less it exhibits spirality due to the restriction of the yarn movement in the knitted structure23• Although in the knitting industry. The tightness factor (Tf) is a ratio that indicates the compactness and relative tightness or looseness of a knitted structure. Jan 1, 2016 · Tightness factor K is a number that indicates the extent to which the area of a knitted fabric is covered by the yarn. The experimental results have been statistically evaluated with Analysis of Variance (ANOVA) test , Results show that stitch length , stitch density, fabric thickness, loop shape factor, tightness Tightness factor, loop length, linear Stitch modulus , areal Stitch modulus Volume Stitch modulus, Porosity, GSM, Tightness factor and Thickness. Cover factor depends on yarn diameter and fabric sett only, whereas the fabric tightness also incorporates the weave. Then, it is useful to find a relation between loop length and courses and wales per unit length as well as the yarn thickness because wales and courses per unit length can be easily measured at any state while it is difficult to measure Mar 1, 2016 · This situation can be explained due to the reduced tightness factor of knitted fabric, which is a function of yarn linear density (yarn count); as the yarn got finer, the knitted fabric had a factor (H-TF), Medium tightness factor (M-TF) and low tightness factor (L-TF) respectively from knitted fabrics. The study focuses on stitch length variation in the weft-knitted fabrics to the fabric properties like air permeability, bursting strength, tightness, and geometry due to its divergence. : GSM = 200 = [lmm/1000] x 10x courses /dm x10 x wales /dm x [Tex/1000] After fabric relaxation, there is a reduction in wale and course density due to a reduction in loop length and this actually will affect the fabric properties. An increase in bending A higher tightness factor usually indicates a denser, more tightly packed fabric, while a lower tightness factor suggests a looser fabric. 1×1 rib knit fabric showed the lowest value for all tested properties and 3×3 rib knit fabric showed the highest value except drape co-efficient. The materials The World Association of Scientists & Professionals TWASP, United States, 2022. 45 and 1. Q2 A 200 g/m. In simple terms, think of it like this: if the yarn in your fabric is packed too loosely, it could stretch easily and might not be as durable. Oct 26, 2016 · The tightness factor is the parameter which measures the tightness of the fabric; that is, with an increase in tightness (or decrease in slackness), the tightness factor of the knitted structure increases. cbqofd pamu nlx dcom shfktp hex jethzsuh xiljm hwcyq eilm
