It is often desired to determine the bending stiffness of a fabric or other material. Some simple tests have been utilized for this purpose. The tests considered here involve a horizontal cantilever, vertical cantilever, hanging ring, heart loop and hanging pear loop. Usually a strip or loop of material is only subjected to its self-weight in these tests. In some cases, an additional weight is applied and causes greater deformation; this problem is analyzed here. In each test, the position of an extreme point is measured under the self-weight and applied load. Polynomial approximations are proposed to obtain the bending stiffness of the material.

“…At the microscopic scale, yarn is made up of fibres that interact with each other, but the bending rigidity of the yarn is not the sum of the bending rigidity of the fibres. The relationship between the mechanical behaviour of fabric, yarns, and fibres is complex [ 14 , 15 , 16 , 17 ]. Bending rigidity in particular determines the correct shape of wrinkles that appear during draping at macroscale [ 18 ] or macroscopic extension of fabrics.…”

The Influence of Structure of Multilayer Woven Fabrics on Their Mechanical Properties

Multilayer woven fabrics used for conveyor belts must be characterized by high mechanical strength. The design process of multilayer woven fabrics for such application requires taking into account the structural characteristics of the fabric, which allows to adjust the final product properties to the dedicated use. The geometry of warp threads—means stuffer and binding is the decisive aspect, which influences the strength properties of multilayer woven fabrics and materials made with their use as well. The aim of this work was to examine the possibility of shaping mechanical strength and bending rigidity of multilayer woven fabrics by changing the order of introducing weft threads into individual layers. The eight variants of multilayer woven fabrics were manufactured using laboratory harness loom. They were produced using different structural models in two weft variants, then tested. The mechanical features were determined, such as breaking force, recovered and unrecovered elongations in cyclic tensile test, stiffness rigidity. The analysis of the obtained results confirmed, that both the model and the order in which the weft threads were introduced into individual layers influence the mechanical strength and bending rigidity of multilayer woven. It was found, that the strength properties characterized by the above mentioned indicators are influenced by the number of threads weaved as both the stuffer and binding warp.

Conveyors belts are used wherever it is necessary to transport materials quickly and promptly. They are made of fabric-rubber core (carcass) and rubber covers. The carcass may consist of several spacers made of synthetic polyamide-polyester fabrics impregnated with a solution of latex that provides an intermediate layer to prevent delamination of the vulcanized composite. The main goal of this research work is to analyse the mechanical properties of conveyor belts during three main stages of production: raw fabric, fabric impregnated with latex, and conveyor belt. For this purpose, nine fabrics of different weaves with a width of 1 m were produced with polyester warp and polyamide weft threads. The fabrics were coated with latex and then vulcanized. Subsequently, the structural parameters and the mechanical properties of each product were measured at each of the three stages of conveyor belt production. This article presents the effect of fabric structure on the mechanical properties of the products of these three production stages. Results show that differences in the mechanical properties of products at different stages of conveyor belt production depend on number of intersections of yarns in woven fabrics. In addition, significant differences were observed in the mechanical properties depending on the applied weaves.
