Study Notes
Weave Design Overview
- Weave design refers to the order of interlacement of warp and weft in woven fabric.
- Plain weave is the simplest weave structure.
- Unlimited woven fabric structures can be created by altering interlacement patterns.
Graphical Representation
- Weave designs are represented on graph paper divided into 8 x 8 boxes.
- Vertical columns indicate warp (ends), while horizontal rows denote weft (picks).
- Filled boxes indicate warp is over the weft; empty boxes indicate warp is under the weft.
Weave Design Repeat
- The basic repeat of a weave design is a fundamental unit repeated to create the finished fabric.
- More repeats may be displayed to illustrate the weave effect clearly.
Elements of Weave Design
- Key elements include:
- Drawing-in draft (DID)
- Lifting order (LO)
- Reed plan (RP)
- These elements are essential for executing a specific weave design on a loom.
Drawing-in Draft (DID)
- Represents the sequence of passing warp yarns through heald frames.
- Derived from the weave design, indicating the number of required heald frames.
Types of Draft
- Four types exist:
- Plain draft
- Straight draft
- Pointed draft
- Mixed or staggered draft
Lifting Order (LO)
- Describes the order in which heald frames are lifted for each pick.
- Must match the number of rows in the weave design and the number of frames shown in the drawing-in draft.
Reed Plan (RP)
- Indicates the number of warp ends passing through each reed dent.
- Two types:
- Regular reed plan: Same ends per dent throughout fabric width.
- Irregular reed plan: Varying ends per dent across the width.
Interconnection of Weave Elements
- Weave design, DID, and lifting order are interrelated; one can be constructed from the other by modifying the others.
- Modifications can be made to either the drawing-in draft or the lifting order to derive new weave designs.
Heald Count and Heald Wires Calculation
- Heald count is the number of heald wires or heald eyes per inch.
- Importance of accurate heald count and wires within weaving frames.
- Example: For a fabric width of 60 inches and 60 ends per inch, total ends are 3600.
- Heald wires and counts calculated per frame based on specific formulas.
