Textiles Exam 3 Review

Types of Looms

*For manual it is narrow as it goes as far as ones wingspan

*Mechanized is faster and limited by width

Loom Motions/ Names

Weaving (Woven)

• Produced by interlacing perpendicular yarns

• Warp (Vertical)

• Weft (picks, filling)

Knitting

• Formed by interlooping yarns in a horizontal or vertical direction

• The loops along the length of a fabric (wales)

• Loops across the width (courses)

Nonwoven

• AKA Fiberwebs

• manufactured directly from fibers

How do you differentiate the fabric types?

Unraveling the yarns

• Wovens can be unraveled in two directions

• Knits cannot be unraveled be in both directions (its too tight)

• Nonwoven fabrics have no yarns

Balanced vs. Unbalanced

• a woven construction in which the same size yarn and the same number of threads per inch are used in both warp and filling directions

  • Strength/wrinkle recovery is similar in warp and filling

• an unequal number of yarns when comparing the number of yarns per inch for the warp and weft

  • yarns in one direction are thicker than in the other direction

  • unbalanced weaves often create a ribbed effect

  • strength/wrinkle recovery are different
