FAQs

Q1:  How do I determine what DPI is needed?
A1:  DPI = Total Reed spaces divided by the Reed width = DPI (Dents per Inch)
Q2: How do I calculate the Reed width?
A2:  The width is determined by the final width you desire after contraction and selvedge waste.
Q3: What is contraction?
A3:  The contraction is the amount of fabric width lost in the weave process. Contraction = (Reeded width – Cloth width off loom) divide by Width
Q4: What is optimal Air Space and how do you calculate this?
A4:  Air Space: The amount of space available between Reed Dents. To determine % Air Space when the DPI and Dent thickness are known: DPI x Dent thickness (inches) x 100 = % Dent Wire.
Q5: How do I know if my Reed is to full or over occupied?
A5:  Yarn occupancy: The % of yarn that occupies the space between two dents; Occupancy = (mm yarn in 1” inch) / (mm air space in 1” inch) x 100
Q6: What is air flow and how do I know what is needed?
A6:  Air Jet Reed air flow is how much dynamic pressure that is needed to allow for accurate pick insertion at a required distance.

Q9: Do I need Selvedge Dents?
A9: YES, If there is a high end count in Selvedge.
