Textile compression materials properties

Grease Retention, Wrinkle Resistance, and Durable Press. On bending or creasing of a textile material, the external portion of each filament in the yam is placed under tension, and the internal portion is placed in compression. Thus, the wrinMe-recovery properties must be governed in part by the inherent, tensional elastic deformation and recovery properties of the fibers. In addition to the inherent fiber properties, the yam and fabric geometry must be considered. 

The measurement of compressive properties of plastics is covered by ISO 604 [44]. Unlike with the tensile test a single document is able to cover a wide range of materials, since test geometries and other conditions tend to be less variable between types of plastic than is the case for tensile testing. Nevertheless, there arc types of materials that the standard does not purport to cover, and these include textile reinforced plastics, cellular materials, and sandwich constructions involving cellular materials. 

Composite materials are combinations of two or more materials with different, often complementary properties (Cheremisinoff 1997). Polymeric natural fiber composites have traditionally been manufactured using short reinforcement fibers dispersed in a matrix (Van de Velde and Kiekens 2001) or compression molded from a nonwoven textile (Mueller and Krobjilowski 2003). These applications usually contain low fiber volume fractions and lack control of fiber angles, resulting in their primary use as nonload carrying components (Svensson 1997). The role of stiff and strong reinforcing fibers in a composite is to carry the load and improve mechanical properties of the matrix material. Regardless of fiber type (carbon. 

Thermal properties of textiles can be considered as thermal conductivity, thermal resistance, thermal absorptivity, and thermal emissivity. They are influenced by fabric properties such as stmcture, density, humidity, material and properties of fibers, type of structure, surface treatment, filling and compressibility, air permeability, and so forth [24].

A liber or a filament (a continuous form of fiber) is the fundamental unit of textile materials. It has a unique combination of high strength (tensile, bending, torsional, or compression), high flexibility (i.e., low modulus), extensibility, and shows recoverability on deformation. Most of these properties are observed in one principal direction, which is known as the axis of the fiber. Since all textile structures from one to three dimensional (yam, fabric, or braids, etc.) are built using this basic structural unit, these stmctures also possess the above unique properties.
