Week 11 – Complex Weaves
Objective: to observe the interlacing patterns of various complex weaves and to
judge some of the characteristics of these weaves.
Leno Weave
1. Observe and mount the leno sample. Sketch the interlacing pattern beside
it. How do the properties of a leno weave differ from a plain weave of the
same low cloth count? What is a major advantage of the leno weave?
Sketch
Mount Sample
Pile Weaves
1. Unravel enough yarn to release the pile from the corduroy and velvet
samples. Shake the small pieces of pile onto a surface of contrasting
colour. Look at the small pieces and determine whether they are in the
sample of a V or W. (Figure 21)

Figure 21. V and W pile
2. Fold fabric first vertically, then horizontally. Which direction shows distinct
rows of pile? Which direction forms the pile?
3. Observe the terrycloth sample. Is the pile effect cut or uncut?
a. Is the pile the same on both sides?
b. How many weft does one pile loop float over?
c. How many ground warps are there between each set of pile loops?
d. What is the approximate ratio of the length of the ground warp to pile
warp?
e. What weave is the ground fabric?

Warp pile – Velvet
Warp pile – Terrycloth
Weft pile - Corduroy
Results & Study Questions:
1. With the cut pile samples (velvet or corduroy) which pile, V or W, is
probably more able to stand up to wear and why?
2. What other characteristics of the pile fabric structures influence how long
the fabric will last?
3. How would pile fabric compare to plain weave flat fabrics in the following
fabric properties?
Warmth Flammability
Durability Absorbency
Document Summary
Objective: to observe the interlacing patterns of various complex weaves and to judge some of the characteristics of these weaves. Leno weave: observe and mount the leno sample. Pile weaves: unravel enough yarn to release the pile from the corduroy and velvet samples. Shake the small pieces of pile onto a surface of contrasting colour. Look at the small pieces and determine whether they are in the sample of a v or w. (figure 21) V and w pile: fold fabric first vertically, then horizontally. Which direction forms the pile: observe the terrycloth sample. In some fabrics with a woven-in cut pile, there is a direction to this raised pile surface on the face of the fabric along its length. In sewing with these fabrics, care must be taken that all pieces of the product are cut with the pile running in the same direction, or different sections of the product will appear to be a different colour.
