`
`During recent years,spacer fabrics have become a new generation among textile fabrics.From the technology
`point of view,they are not quit new,they practically have existed since 15 years,however they have gained
`commercial importance since a few years only.
`Conventional textile fabric do not meet the brilliant features of spacer fabrics or only as a compounded fabric
`combination.Therefore spacer fabrics were in short time successful in getting market share as substitutes for
`laminates,in sports and safety wear,as basic construction for composites.for filter and in the medical field.
`
`Spacer fabric are warp knitted
`double face construction of which
`both fabric faces are interconnected
`by the spacer yarn.
`Both fabric face can be equal or
`different,of dense structure,plain or
`patterned with small design or with
`a napped surface on one side.

`
`Both faces or only can be of open structure,even with different mesh size on each side.By the choice of stitch
`construction,spacer fabric can be almost stable but also of controlled stretch used elastic yarn.

`
`For connection of both fabric
`generally mono filament yarn is
`used.The thickness of the spacer
`yarn depends amongst other criteria
`on distance between the fabric
`space and whether the space is
`knitted with one guide bar or with
`two guide bars each one knitting in
`opposition to each others.
`
`Spacer fabric are knitted on warp knitting raschel machines with two needle bars.Depending of the product and its
`requirement,a minimum of four guide bars normally,however five to seven guide bars are in use.The distance
`between the needle bars is adjustable in certain ranges and is different for the various machines types for knitting
`spacer fabrics.

`
`Spacer fabrics and their way of manufacture
`
`Spacer fabrics produced on double needle bar raschel machines.The distance between the needle bars
`respectively the trick plate is adjustable in certain ranges depend on the type of the machine which is used for the
`manufacture of spacer fabric.
`For the construction type A -F two guide bars for each face are normally used,i.e. including the bar for the space,a
`total six guide bars are used.
`For certain applications one or both faces can be knitted with one guide bar only.The spacer up to 3 mm thick
`could be knitted with one guide bar for the space,preference however should be given to two bars half set,both
`knitting in opposition to each other.
`For many applications it might be possible to knit the spacer construction half set,whenever the required shore
`reading and resilience do allow that.By this method the content of expensive mono filament yarn can be reduced
`by approx 50%.

`
`For spacer fabric with a patterned decorative face up to three guide bars are needed,in this case two guide bars
`are available for the opposite face and two for the space.
