REED'S SPECIFICATIONS, CALCULATION OF DENT WIRE THICKNESS

REED'S SPECIFICATIONS:

Reed of the loom is a very important part. It is directly associated with fabric quality and looms efficiency. Improper reed specifications directly affect the warp breakages. High warp breakage rate due to improper reed specifications reflects in the form of poor fabric quality. Weaver also faces trouble during the passing of knots through the dent of the reed. If the material of dent wire is not proper as per fabric quality to be woven. The dent wire gets band during broken ends drawing. If the material is not proper, the rust can be deposited on the surface of the dent wire. This rust causes high warp breakage during weaving.

Now the question arises, how to place an order to reed supplier for particular fabric quality.

A weaver should consider following reed's specifications before placing an order to the reed supplier:

Overall reed width

Overall reed height

Working reed height

Dent wire thickness

Dent width

Dent' material

Height of top baulk

Height of bottom baulk

Reed thickness

Air space

Reed count

Overall Reed height, working reed height, dent width, the height of top and bottom baulk, reed thickness and air space are fixed for a particular loom by loom manufacturer.

Overall reed width =?
Overall reed height 99 mm
Working reed height = 75 mm
Air space = 65 - 70 %
Dent wire thickness = ?
Dent width = 4 mm
Dent' material = standard steel wire
Height of top baulk = 8 mm
Height of bottom baulk = 16 mm
Reed thickness = 8mm

Here we will discuss reed's specifications for the following quantity.
Fabric width = 120”
EPI               = 110
PPI.              = 90
Warp count. = 40s
Weft count   = 40s
Reed.             = 106 ( stock port system)

Reed width:  this parameter is decided after calculating the reed space to be used during the weaving of a particular fabric.

 we have to weave 120” fabric width. Now we calculate the required reed space for 120” wide fabric. Suppose reed space comes 124”. Now we will find out the overall reed width.

Dent thickness:  It is a very important specification of the reed. It plays a decisive role in the calculation of air space.  The method of calculating the dent thickness is given below:
