The Secret Life Of Industrial Textiles

A view into the vast field of manufacturing and application of industrial textiles

A view into the vast field of manufacturing and application of industrial textilesThe technical and technological application of textiles has become a rapidly growing field, especially over the past two decades. For example, even though some textile seat belts for automotive applications were installed before the 1960s, nobody imagined then how large a role textiles would play in passenger safety. The demand for seat belts, as well as supplemental restraint systems such as air bags, is huge. And while this is only the result of about two decades, we now have a better feeling for how the market for such technical safety textiles will grow.
There are thousands of applications of textiles today for industrial and consumer usage. Additionally, many potential uses have not been explored because end users arent aware that textile fabrics and composites can effectively replace many traditional materials. Industrial textiles are not in the spotlight like flashy brand-name apparel textiles and live almost a secret life, often hidden from the eye of the end user. And the manufacturers of high-technology industrial textiles are (understandably) very secretive about their manufacturing processes and the design of their fabrics. The market for industrial fabrics and engineered textiles is growing constantly and becoming increasingly significant. This leads to technical developments and innovations of advanced textiles for new tasks. A growing awareness can be observed of environmental demands, e.g., methods of filtration, or of the substitution of textiles for conventional materials. A great effort is geared toward the development of cheaper, easy-to-install and lightweight textile components (in the automotive industry, for example) based on textiles.Dream It, And It Will Be TextilesThe following list of applications is based on a summary of fields that was compiled over the years by Sulzer Textil Ltd., Switzerland. The company has been in the field of woven industrial applications for many decades and set many of the original benchmarks for this sector with the introduction of the Sulzer Projectile weaving machine. In geotextiles, woven industrial fabrics are selected for their stability and strength, while nonwovens are often selected because of their cushioning, damping and liquid filtration properties. Each individual manufacturing technology, in combination with specific fibers, has certain advantages in a particular field. It seems that the nonwovens technology has an even more impressive growth rate over the past years when compared to all other industrial textile manufacturing technologies. Unlike consumer-oriented textile producers, the industrial textile manufacturers face challenges presented by fibers that are extreme in nature and chemical origins. Also, physical and mechanical properties of fibers and yarns are often very different from those used in typical consumer textiles. The distinct design of fabrics for industrial applications often requires special devices and setups on the production machinery. Textile manufacturers are understandably very secretive about machine settings and installations. Many of the nonwovens installations show a specific custom layout, and weavers have to purchase expensive, wide, reinforced or specially equipped weaving machinery to be able to produce the desired industrial fabrics. However, it seems to pay back when one compares the profit margins of the industrial fabric segment with those of the rest of the textile industry.Industrial TextilesAs already mentioned, woven textile products, nonwovens and knitted textiles share each segment of industrial textiles, while the actual percentage assigned to each individual manufacturing technology may vary from application to application. The technical specification profile, cost-effectiveness and practical performance determine which manufacturing technology receives the lions share. The following list provides a general overview of all major fields in which textiles play a significant role.
  • Protection and safety-related textiles
  • Public services
  • Medical and healthcare applications
  • Agriculture, horticulture and fisheries
  • Buildings and light structures

GeotextilesThis is a vast and rapidly growing field of applications. It is estimated that only about 20 percent of all possible applications for textile products have been developed. It is usually the end user who cannot imagine a textile product that could lead to significant improvements and savings. However, for geotextile applications, it is often the textile manufacturers drive to research and educate their customers that leads to new textile products. Companies like Synthetic Industries, Chattanooga, Tenn., for example, offer a broad range of geotextiles for civil and environmental engineering, as well as fabrics for erosion control and storm water management. The company offers high-strength woven geotextiles for soil stabilization, reinforcement and containment; and nonwoven geotextiles for drainage, separation, cushioning and pavement overlay. Its geotextiles and erosion-control products are distributed in more than 50 countries. Following are more applications in geotextiles.
