What are new and extremely attractive to the manufacturer are the growth in industrial textiles and its application in the sectors such as agriculture, construction, geotextiles, automotive , protective apparel, electronics textile etc.
This rapid increase in market potential has led these high profile manufacturers to develop specialized fabric for knitting and serving the end purpose efficiently.
In this paper focused various knitted fabrics used for manufacturing of industrial textiles have been reviewed. Unlike woven fabric, knitted fabric consists entirely of horizontal parallel courses of yarn. The courses are joined to each other by interlocking loops in which a short loop of one course of yarn is wrapped over the bight of another course. Knitting can be done either by hand, described below, or by knitting machine.
In practice, hand knitting is usually begun or "cast on" by forming a base series of twisted loops of yarn on a knitting needle. A second knitting needle is then used to reach through each loop or stitch in succession in order to snag a bight of yarn and pull a length back through the loop.
This forms a new stitch. Work can proceed in the round circular knitting or by going back and forth in rows. Knitting can also be done by machines, which use a different mechanical system to produce nearly identical results. The knitting process consists of interconnecting loops of yarn on powered automated machines. The machines are equipped with rows of small, hooked needles to draw formed yarn loops through previously formed loops.
For this can be used roving of glass, high tenacity polyester, armid or carbon as pillar threads and weft threads. These fabrics are used for reinforced composites. However, there is the advantage that yarns are directly oriented and lie absolutely straight in the fabric. This means that there is no loss of tenacity as in the woven due to its crimp effect.
Furthermore, the yarn-protective inlay system prevents all fiber damage. Innovation 3D-Glass-textiles, manufactured on double needle bar high speed Raschel machines of LIBA find ever more fields of application within the area of composite materials, technical textiles.
Variety Whether as isolation layer in the boat- and container construction or as double-walled tanks, these so-called spacer fabrics perform particularly well.
Caused by the fabric construction, after laminating, a more stable, lightweight and ductile composite develops. Flexibility Depending on the final product, the thickness of the fabric can be adjusted between 3mm to 15mm directly at the machine. By using a special design technique, a thickness of even 25 mm can be achieved.
Geotextiles Application: Geotextiles Application Geotextiles are permeable textile materials which are designed for use in civil engineering applications such as erosion control, soil reinforcement, separation, filtration and drainage etc. Geotextiles are forecast to be the fastest growing sector within the market for technical textiles. Warp knitting is well established in this area and an extremely wide range of structures spanning from nets and grids to monoaxial, biaxial, triaxial, multiaxial as well as composite and three-dimensional spacer materials are all used as geotextiles.
Grid shape structures grip the soil more effectively than plain smooth fabrics. Also, for extremely high performance and critical applications — such as land reclamation, construction of high walls and water reservoir embankments — high strength up to k N m-1 biaxial raschel structures are more suitable.
These fabrics have high strength, low extensibility, and high modulus, above all, high tear strength. A new and novel technology has been developed and commercialised at Bolton Institute, which enables the manufacture of monoaxial and biaxial specialist natural fibre geotextile structures for soil reinforcement.
The technology is based on flat knitting, in which high strength coarse and hairy natural fibre yarns such as sisal, coir etc can be inlaid in the machine or cross, or both directions and incorporated within a knitted structure made from jute, flax and other natural fibre yarns, such as cotton, viscose, Tencal, wool etc. It is possible to manufacture designer natural fibre geotextile structures for specific short-term solutions.
These Directionally Structured Textile Fabrics have been patented, and are currently being commercialised for mass production. Figures 1 and 2 illustrate the novel weft knitted structures and Figures 3, 4 and 5 shows the modified mechanically operated flat machine which enables either warp or weft or both threads to be incorporated within the fabric structure. It is also used with foundations, soil, rock, earth or any other related material as an integral part of human man-made project, structure or system.
This specification covers circular-knit geotextiles for use on the outside of perforated pipes and Class B geo-composites in subsurface drainage applications.
Material covered by this specification comprises Type A and Type B fabric geotextiles, which have been used extensively as filtration geotextiles in combination with subsurface drainage pipes. The geotextile can be manufactured from polymeric materials by a circular-knit process, which will ensure a consistent, continuous fabric without seams.
Tests for water permittivity, apparent opening size, and puncture strength shall be performed and shall conform to the requirements specified. Per service requirement, additional tests for chemical resistance and durability may be performed as well. This specification covers circular-knit geotextiles for use on the outside of perforated pipes and Class B geo-composites per Specification D in drainage applications.
The tests used to characterise the geotextile are intended to ensure good workmanship and quality, and are not necessarily adequate for design purposes in view of the importance of environmental factors and specific performance objectives. Tests have been selected with essentially neutral aqueous systems in mind.
Other tests may be necessary to establish chemical resistance and durability under the conditions of a particular application. This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.

Knitted Spacer Fabrics Warp and weft knitted spacer fabrics continue to find new and novel product applications and it is generally recognized that spacer fabrics will be extensively used in the future in a wide range of products, mainly due to the fact that an extremely wide range of possibilities are available to tailor make their aesthetical, functional and technical properties for applications 2. Warp Knitted Spacer Fabrics Warp knitted spacer fabrics are structures that consist of two separately-produced fabric layers which are joined back to back.
The two layers can be produced from different materials and can have completely different structures. The yarns which join the two face fabrics can either fix the layers directly or space them apart. It is this three-dimensional space which is the special feature of these structures. Typically, spacer fabrics can be from 1 to 15 mm thick, with the two faces being from 0. The major single feature of warp knitted spacer fabrics is that virtually any thickness can be obtained, depending upon the type of machinery used and the type of yarns and structures used.
The warp knitted spacer fabric with a thickness of over mm 4 inches for use as a seating fabric for sports cars. Knitting element of sinker Spacer structure manufactured in one process Up to 15 mm spacer distance Up to 3, 3 m full fabric width Large pattern variety for outside cover fabric and S pacer structure.
Karl Mayer spacer machine RD6N: In which guide bars 1 and 2 knit the front base fabric on the front needle bar only and guide bars 5 and 6 knit the other separate base fabric on the back needle bar only. Guide bars 3 and 4, which carry the spacer threads knit on both needle bars in succession. The thickness of the spacer depends upon the distance between the two needle bars and can be varied between 1 and 15 mm.
In theory the material used in guide bars 1 and 2; 3 and 4; and 5 and 6 can be different, as well as the structure of the two base fabrics can be completely different.
It is possible to vary the structure from an inelastic, elastic, solid, net or a specific textured surface independently in each face fabric. Furthermore, the compression and resilience properties of the spacer can be altered at will, depending upon the material and the pattern chains of the threads in guide bars 3 and 4. The major benefit of using spacer material is to replace polyurethane, neoprene and other types of foams which are laminated to textile fabrics for creating bulk, softness, flexibility, resilience etc.
These foams, however, have some serious drawbacks. For instance, foams are generally flammable; they are extremely uncomfortable due to extremely small cavities. Their thermo physiological properties are poor, their compression and resilience properties deteriorate with time and their mouldability, delamination, maintenance of original thickness when moulded into complex three-dimensional shapes, washing and drying properties are often poor and not up to the standard required.
Weft Knitted Spacer Fabrics Weft knitted spacer fabrics can be produced on circular double jersey machines as well as electronically controlled flat machines.
The major advantages of these structures are: P lain as well as colour and design and surface texture effects can be produced on the face of the fabric knitted by the cylinder needles; and Shaped and true three-dimensional structures can be produced on electronically controlled flat machines. The major limitations of weft knitted spacer fabrics are: The thickness of the spacer is normally limited to between 2 and 10 mm The basic structure of the spacer fabric is limited to either knitting the spacer threads on the dial and tucking on the cylinder, or tucking the spacer threads on the dial and cylinder needles.
It is obviously more practical to use tuck stitches with spacer monofilament yarns in order to ensure that the spacer yarns lie correctly inside the knitted fabric and prevent the face and back of the fabric from having a rough or harsh feel. Knitting Constructions: The structure of a circular knitted monofilament spacer fabric is Produced on circular interlock gaited machines are shown in Figures.
Three different yarns are required for each course: Yarn for the dial needles Yarn for the cylinder needles Spacer yarn, normally mono filament yarn. Only innovative products will be able to open up new markets and new horizons for the textile industry. To achieve this, it is essential to invest in future research and researches.
In the coming years, knitted fabrics will increasingly take on industrial functions. Fabric will combine the functions of medium, carrier and interface for an extremely wide range of industrial applications.
This new generation of industrial fabric makes considerable new demands on the innovative ability within the clothing industry. What is needed is not simply the conveyance of knowledge but the development of truly creative researchers.

Knitted fabrics can be made much more quickly and easily than woven fabrics at comparatively less cost. Two yarns forming loops in each course of the fabric knit the fabric. Knitting machines form loops of yarn with many pointed needles or shafts.
Future of textiles from and for space discussed at Techtextil
Knitted fabric is a textile that results from knitting. Its properties are distinct from woven fabric in that it is more flexible and can be more readily constructed into smaller pieces, making it ideal for socks and hats. There are two basic varieties of knit fabric: weft-knit and warp-knit fabric. Weft-knit fabrics are easier to make and more common.

ESD Knitted Fabrics from Conductive Yarns Used as Protective Garment for Electronic Industry
Year of fee payment : 4. Year of fee payment : 8. The present invention relates to a spacer fabric with advanced cushionability, flexibility, and thermal conductivity, and a method of fabricating the same. In accordance with the present invention, the spacer fabric is useful as a car seat fabric.
Knitted fabric is made by taking a section of yarn and folding it over to form a loop during the fabric manufacturing process. There are two main types of knitting machines:. With weft knitting machines, the yarn is worked in transversal ranks and the needles move individually on the circular beds. On flat bed machines, the needles move along with a bar.
Warp knitting is a family of knitting methods in which the yarn zigzags along the length of the fabric; i. For comparison, knitting across the width of the fabric is called weft knitting. Since warp knitting requires that the number of separate strands of yarn, or ends , equals the number of stitches in a row, warp knitting is almost always done by machine rather than by hand. Credit for the invention is usually given to a mechanic called Josiah Crane in
Nowadays, interest in protection against electrostatic discharge ESD , regarded as an important issue, is still growing. ESD may lead to serious economic losses and can also be hazardous to humans.
