Textile forming

As is known of glass fiber-reinforced plastics, the mechanical and physical properties of composites, next to the fiber properties, and the quality of the fiber matrix interface, as well as the textile form of the reinforcement primarily depend on the volume content of fibers in the composite. 

Materials based on amorphous silica fibres are of special interest these are manufactured in a variety of textile forms (cloth, tape, rope, etc.) which can be used for several applications (thermal, electric insulation) for service temperatures generally up to about 1000°C. Typically they contain 93-96% Si02 about 4% Al203 and small quantities of Ca or alkali oxides. 

Usable for all kind of fibres and all textile forms, as yarn, woven or knit fabric, garment, nonwovens... 

The pellet lengths were limited by the position of the breaker plate installed on the interior surface of the cover of the die. However, the centrifugal force from the rotating die and impacts from loose pellets within the shell cover of the die, cause the pellets to break off at random lengths. Also, included pieces of plastics and textiles form planes of weakness and the pellets break shorter. 

During World War II and the Korean War, great progress was made in vascular surgery. Based on observations of sutures placed in the aorta, a textile was shown to have the ability to retain a fibrin layer, which then organized into a fibrous tissue layer. A number of materials were tested. Selection of these materials was based on two criteria (1) minimal tissue reactivity and (2) availability in a textile form. 

The first public report that acrylic fibers could be rendered fireproof by heat-treating them in air or Inert atmosphere at 200°C was published by Houtz In 1950 [14]. The material was popularly called "black Orion". Several companies in the U.S. patented fireproofed fabrics based on this process, including DuPont, Johns-Hanvllle, and Carborundum [15], Various textile forms of this material are commercially available today [16]. 

This chapter describes the types of natural fibres that are used for biodegradable geotextiles, the important properties of these fibres, the process and structures of the textile forms into which they are converted, and most importantly their geotechnical end-uses. First, however, it is necessary to understand what geotextiles are, and also their primary functions. 

Activated carbons have a large adsorption capacity, preferably for small molecules, and are usedfor purification of liquids and gases. By controlling the process of Carbonization and activation, a variety of active carbons having different porosity can be obtained. Activated carbons are used mainly in granular and powdered forms, but can also be produced in textile form by controlled carbonization and activation of textile fibers. Other terms used in the literature active carbons, active charcoals. 

E-broidery, embroidery with conducting threads, is described by Post (1996) and Post et al. (2000). The sewability of various electrically conducting yams is compared. Stainless steel threads have advantages because of their resistance to corrosion, biological inertness, availability in textile form and low cost. However, it is difficult to attach them to existing components. Composite yams made from steel and polyester can be sewn by machine (Post et al., 2000). 

Clothing and upholstery textiles are often subjected to a soft frictional wear that normally does not cause holes in the fabric. But often single fibers are extracted from the textiles, forming pills when combined with other loose fibers on the textile s surface. This can lead to an unwanted and messy appearance of the textile.
