Definition and scope of technical textiles?

The definition of technical textiles adopted by the authoritative Textile Terms and Definitions, published by the Textile Institute1, is ‘textile materials and products manufactured primarily for their technical and performance properties rather than their aesthetic or decorative characteristics’.

Such a brief description clearly leaves considerable scope for interpretation, especially when an increasing number of textile products are combining both performance and decorative properties and functions in equal measure. Examples are flame retardant furnishings and ‘breathable’ leisurewear. Indeed, no two published sources, industry bodies or statistical organizations ever seem to adopt precisely the same approach when it comes to describing and categorizing specific products and applications as technical textiles.

What is Industrial textiles? Classification of industrial textiles?

Textiles are the largest items of application next only to engineering goods; textiles have found wider acceptance in industry, house hold, aerospace and apparel field.etc.

Today industrial textile has an old tradition, in the 20 th century when man-made fibers became available, the range of industrial textiles was rapidly widened by textiles before, These are currently used to produce fabric reinforced constructions, it is only in the last few decades that industrial textiles have become a commonly considered special group of textiles products, where industrial fabric of the textile field has grown more rapidly than house hold textile and apparel

Types of geotextile? Raw material & basic properties of geotextile?

As we know, the prefix of geotextile, geo, means earth and the ‘textile’ means fabric. Therefore, according to the definition of ASTM 4439, the geotextile is defined as follows

"A permeable geosynthetic comprised solely of textiles. Geotextiles are used with foundation, soil, rock, earth, or any other geotechnical engineering-related material as an integral part of human-made project, structure, or system."

The ASAE (Society for Engineering in Agricultural, Food, and Biological Systems) defines a geotextile as a "fabric or synthetic material placed between the soil and a pipe, gabion, or retaining wall: to enhance water movement and retard soil movement, and as a blanket to add reinforcement
and separation." A geotextile should consist of a stable network that retains its relative structure during handling, placement, and long-term service. Other terms that are used by the industry for similar materials and applications are geotextile cloth, agricultural fabric, and geosynthetic.

What is Geotextile & Is there Applications ?

INTRODUCTION

According to the historical record, it is believed that the first applications of geotextiles were woven industrial fabrics used in 1950’s. One of the earliest documented cases was a waterfront structure built in Florida in 1958. Then, the first non woven geotextile was developed in 1968 by the Rhone Poulence company in France. It was a comparatively thick needle-punched polyester, which was used in dam construction in France during 1970.

Geotextile

Geotextiles are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect, or drain. Typically made from polypropylene or polyester,geotextile fabrics come in three basic forms: woven (resembling mail bag sacking), needle punched (resembling felt), or heat bonded (resembling ironed felt).

Classification of Medical Textiles ?

The constituent element of midical textile products for medical applications include materials as fibres, yarns, woven, knitted, nonwoven,PTFE felts and mesh etc.

Depending upon the usage, they are classified as-

1. Healthcare and Hygiene products
2. Extracorporeal devices
3. Implantable materials
4. Non-implantable materials

The classification of Medical Textile or Med tech can be represented in Figure

What is medical textile??

Introduction:

Medical textiles or Med tech is one of the most important, continuously expanding and growing field in technical textiles. Medical textiles represent structures designed and accomplished for a medical application. The number of applications is diverse, ranging from a single thread suture to the complex composite structures for bone replacement and from the simple cleaning wipe to advanced barrier fabrics used in operating rooms. Textile materials and products, that have been engineered to meet particular needs, are suitable for any medical and surgical application where a combination of strength, flexibility and sometimes moisture and air permeability are required. The medical textile industries have diversified with new materials and innovative designs. Recently, application of textiles has started going beyond the usual wound care, incontinence pads, plasters etc., Latest innovation i.e., wide variety of woven, non-woven, knitted forms of textile increasingly finding their way into a variety of surgical procedures. As the healthcare industry is growing enormously in India, the demand for the Medical Textile is also on the rise.

Medical Textiles are defined in various ways, such as:
