Project Information | Planning

Shown on Project Information

This is the primary screen used to determine all the project sizing and calculations.

The Planning screen shows the current WIF dimensions, and predicts, based on the calculation drivers of what the finished size of the cloth will measure. In addition, the number of pieces (repeats of the current WIF) as well as sampling and fringe calculations are used to determine the minimum warp length and yardage required for warp and weft.

In situations where the WIF does not reflect the actual width that will be warped, or length that will be woven, overrides can be entered so that. the yardage calculations will be accurate.

Current WIF

Current WIF Warp Ends - the current value is automatically populated from the current draft. If the warp ends in the WIF do not represent the entire project (such as having the warp ends repeated a number of times), an override width in the reed can be entered on the next yarn requirements tab so that the yarn requirements will calculation properly.

Current Width in Reed The current value is a calculation of Warp Ends in the WIF divided by the Ends per Inch (or Ends per CM). .

Weft Picks The number of weft picks in the current WIF.

Woven Length The number of weft picks times the Picks per Inch or Centimeter.

Finished Estimate Width and Length The calculation drivers are used against the current WIF to determine the estimated finished size of the piece.

Calculation Drivers

The calculation drivers are on the upper left. Initially these values are all zero. Any or all of these can be entered to impact the calculations.

Draw-In -the difference in width in the reed and the fell of the cloth.

Warp Take-Up - this percentage increases the minimum warp yardage requirements based on the bending of the warp yarns as they are woven.

Weft Take-Up - this percentage increases the weft yardage requirements based on the bending of the weft yarns as they are woven

Loom Waste - inches/cm not woven at the start and end of the warp

Shrinkage Width and Length - this is the expected shrinkage after wet finishing the cloth

Length Drivers

In determining the length of the warp, allowances may be entered for the fringe, sampling and number of pieces.

Fringe: The total amount allocated for fringe, such as warp that is not woven between pieces, is entered for the calculation of total warp length required. For fringe that is a part of tie-on or waste at the end, this need not be entered.

Sampling: if test weaving (sampling) is expected before beginning to weave the actual piece, enter a length woven for sampling. This impacts both the warp and weft yardage calculations.

Yarn Required

Click Calculate Yarn to view the calculated requirements for warp and weft yarn. To see the breakdown of yardage requirements by color, see Color Information.

Target Calculation

The target calculation allows you to specify the desired finishd size per piece, and the calculation drivers from the planning screen along with Sett from Project Setup will be used to calculate the necessary width in the reed, number of warp ends and woven length to achieve the target size.

Input the desired finished width and length of a finished piece. The calculated results will show the required width in the reed, number of warp ends and the woven length of a piece required to obtain the finished size.

This information can be used to go back and adjust the WIF to the required warp and weft ends.
