An Evaluation of Drapeability of Jute Fabric

04 Mar 2015-Journal of Natural Fibers (Taylor & Francis)-Vol. 12, Iss: 2, pp 132-140

AbstractFrom the very inception of the Indian Jute Industry, jute fiber has proved its superiority over other fibers particularly in the area of packaging for food grains, in terms of its functionality and reusability due to its considerable tensile strength, low extensibility, and good dimensional stability, which is obviously the natural choice for packaging. One of the growing alternatives in today’s context is the emergence of technical textiles made out of natural fibers which includes geotextile products for geotechnical applications, agrotextile products as well as other such relevant areas. Jute geotextile can certainly be considered as a potential aspirant replacing majority of today’s popular synthetic products which are posing severe threats to our environment thereby adversely affecting the eco-congruity. During the application of jute fabrics of different types at the sites and even in designing garments in the Apparel Sector, it has been observed that the ability of the fabric to assume a graceful a... more

TL;DR: An overview of possibilities to modify fabric drape by printing different geometrical patterns on textile fabric, using a real garment as an example to show the impact of 3D printing on garment drape.
Abstract: Drape is one of the most important properties of fabric, which significantly influences the appearance of a garment or technical textile. Being closely related to stiffness and other mechanical parameters, drape is also influenced by seams and other modifications of the pure textile fabric. In most investigations, the drape coefficient according to Cusick is used to measure drape, using a special drape meter, which allows to quantitatively describing the textile's behaviour in terms of drape coefficient, number of nodes, etc. This article gives an overview of possibilities to modify fabric drape by printing different geometrical patterns on textile fabric. Their geometry and distance also influence on fabric drape. The resulting differences in a real garment using a skirt as an example will show the impact of 3D printing on garment drape.

Abstract: Amongst the different property parameters of the produced fabric, drapeability of fabric is one of the crucial parameters with respect to end uses. It is the ability of fabric to hang freely in graceful folds when some area of it is supported over a surface and the rest is unsupported. During the application of different fabrics, both in industrial and apparel sector, it has been observed that the ability of the fabric to assume a graceful appearance of the contour is very vital conveying the significance of drapeability of the fabric. With the growing environmental concerns and eco-sustainability, the global emphasis is towards the application of eco- concordant, bio-degradable, renewable green products and this has inclined towards the natural fibre-made fabrics scoring them over their manmade counter parts and making them a natural choice for the mankind. The natural fibre-made fabrics have proven records of efficacy to prove their mettle match with manmade fabrics in different areas of application. This paper has reviewed and analyzed the various attributes of natural fibre-made fabrics such as jute, cotton, silk and wool focusing mainly on their draping behavior, determining their strengths and weakness considering the future direction of research to overcome their deficiencies.

Abstract: In judging the feel or “handle” of a material, use is made of such sensations as stiffness or limpness, hardness or softness, and roughness or smoothness. It is desirable to devise physical tests that analyse and reflect the sensations felt and assign numerical values to the measurements. The present paper describes tests that reflect the first groups of sensations, namely, stiffness and hardness, whilst the sensation that is experienced in stroking a material, obviously connected with frictional properties, will be dealt with in another paper. An instrument is described on which it is possible to measure the angle through which a specimen of cloth droops when a definite length is held out over an edge. By means of a mathematical formula that is fully developed in an appendix to the paper this angle is converted into a term called the bending length of the material. This quantity may be defined as the length of fabric that will bend under its own weight to a definite extent. It is strictly a meas...

Abstract: The draping behaviour of fabric treated as an orthotropic shell membrane is predicted by using a geometric non-linear finite-element method, and the results are compared with actual behaviour. A drape tester employing photovoltaic cells was designed and constructed to determine the drape coefficient of fabric specimens of 10-in. diameter. The warp- and weft-direction tensile moduli of these samples were determined by using a Kawahata Tensile and Shear Tester, and literature values of Poisson's ratio were obtained. With this approach, excellent agreement between experimental and predicted drape coefficients resulted. For a 100% cotton plain-weave fabric, a drape coefficient of 68.4% was experimentally determined as compared with a predicted value of 71.0%.

Abstract: The dependence of the drape of fabrics on bending stiffness and shear stiffness has been investigated A version of the Fabric Research Laboratories Drapemeter is described, and the drape coefficient obtained is used as a measure of the fabric drape The regression of the drape coefficient on bending length for a large number of fabrics was highly significant, and the addition of shear stiffness to the regression made a highly significant difference The regression equations provide the relations between the variables for the conditions used Theoretical values of drape coefficient for zero shear stiffness were lower than the measured values

Abstract: is said to have good draping qualities when the configuration is pleasing to the eye. Obviously, then, the word &dquo;drape&dquo; is a qualitative term. The textile industry realizes the importance of understanding the phenomenon of drape and is anxious to be able to measure it quantitatively. Numerous &dquo;drape tests&dquo; have been reported in the literature, but none have presented any correlation between the data obtained and subjective evaluations. This is largely because of the failure to realize that drape may not be determined conclusively by those tests which involve two-dimensional distortions of the fabric samples. (These

Abstract: A shear flexible shell theory is used to predict the drape of fabrics. The fabric is considered a continuous, orthotropic medium. Finite element formulations are used to numerically solve governing equations under specific boundary conditions. Initially, the fabric is assumed to be a flat plate, which goes through large deformation during the process of draping. The load (fabric weight) is applied in steps to the model. During each step, a Newton-Raphson iteration method is used to solve nonlinear equilibrium equations under current load level. The material characteristics used in the model are Young's modulus in the warp and weft directions, shear modulus, and Poisson's ratio. Simulation of a 30 × 30 cm fabric draped over a 12 × 12 cm table is achieved in less than eight minutes of CPU time on an IBM RS 6000 workstation.
