INTRODUCTIONSpacer fabrics are fabric structure composed of two separate layers of fabric web which are joined together by spacer threads or fabrics of varying rigidity
Spacer fabric is a stable pressure tolerant material.
Spacer fabric is a breathable, resilient, flexible and soft. They comes in the variety of weights, colour, textures and designs.
An important advantage is the low weight in proportion to the large volume..
.Knitted spacer fabric represents a special product group within this sector because of their excellent crush resistance, breathability, and 3D appearance. construction can alter the amount of air incorporated in the assembly.
Special physical attribute of Spacer Fabric Lightweight, soft, pleasant on the skin Offer active breathing properties Pressure-elastic Transport and absorb moistureDefinable elasticity properties Thermo-regulating propertiesWash-resistant Ageing resistant and capable of sterilization
Applicat ions :
The application areas of spacer fabric are unlimited ranging from healthcare, safety, military, automotive, aviation and fashion. Currently it is being largely used for functional clothing comprising pads, sports shoes, shoulder pads, knee and elbow protectors etc. Medical applications Marine Market Transport Market Building & Construction Market Corrosion Industry Wind Energy Industry

There are different Knitting Techniques used for Spacer Fabric Manufacturing
• Warp Knitting • Weft Knitting • Flat Bed knitting
Techniques Used for constructing spacer fabric
Out of various forms of knitted fabrics, the V-bed arrangement allows production of spacer fabric, which is simply a construction with tuck stitch connections
The production of spacer fabrics is supported by positively controlled sinkers on both needle beds, which press down the last row of stitches during the formation of new stitches or other knitting operations

The thickness which can specifically be designed, depending on the gauge of the machine and the material selection (i.e. 4-4.5mm of thickness for a fabric coming from a machine of gauge
The different degrees of softness, which can be set in dependence of the angle of the inlaid tuck stitch and the chosen material.
The special fabric construction, which allows an excellent drape-ability; the fabric tends to keep the form, it is brought in.
The shaping ability similar to the regular fully-fashioned knitwear pieces. The spacer fabrics can also be knitted to shape.
Characteristics
Cushioning elements for orthopaedic use Support fabrics in casting elements, which are
used to support and fix broken limbs in defined positions.
Incontinence pads made out of superabsorbent fibres.
Special, ready to wear bandages
Applications of flat knitted spacer fabric
An important field of application is wound care and prevention of chronic wounds, in particular pressure sores
S.F also used in medical applications such as orthopaedics, prevention of decubitus for the long term bedridden, for surgical applications and convalescence, as well as for incontinence products.
Other medical uses of spacer fabrics are pressure relief, Multilayer compression stocking or bandage system, Bandage for the ankle joint, Absorbent diaper with therapeutic orthopaedic pad.
