Unity
What are the fabric structures?
- Woven: warp, weft, selvege
- Knitted: course, wale
- Non-woven
Plain weave description, properties and example
- Simplest, tightest and cheapest
- 1 weft 1 warp alternation
- Strong and smooth, resilient
- Calico
Twill weave description, properties and example
- Warp and weft interlace to form diagonal lines
- 1 weft over 2 warp then under 1 or 2
- Strong, firm, resists snags
- Denim
Satin weave description, properties and example
- Warp or weft yarns pass over 4 or more yarns before passing under 1
“Floats” - High lustre, drapes well, poor abrasion resistance (snags easily)
- Satin
Jacquard weave description, properties and example
- Intricate weaves by manipulating individual warp yarns to create a pattern, expensive
- Lustre contrasts, stable, snags
- Brocade
Crepe weave description, properties and example
- Random arrangement of floats - “pebble effect”, woven under tension
- Wrinkle-free, comfortable, good to excellent drape
- Bandages
Pile weave description, properties and example
- Base fabric with plain or twill weave with extra warp or weft yarns, 3D structure
- Good insulator, absorbent, soft
- Towelling, velvet
Single knit description, properties and example
- Constructed by weft knitting, definite right and wrong side
- Unravels, good elasticity, low to medium drape
- T-shirts, jumpers
Double-knit description, properties and example
- Formed using two sets of needles,
It looks the same on both sides - Resilient, low elasticity, good drape
- Underwear, dresses
Pile knit description, properties and example
- Formed using two sets of yarns
- One forms base of fabric
- Other forms are looped
- Medium drape, medium elasticity, poor durability
- Towels, beachwear, rugs
Tricot knit description, properties and example
- Knitted on a flatbed knitting
machine using two sets of warp threads that move from left to right with each new row. Fine and lightweight - Good drape, good elasticity, good resiliency
- Lingerie, curtains
Lace knit description, properties and example
- Knitted on Raschel flatbed knitting machine. Usually have elaborate patterns
- Snags easily, Highly decorative, medium drape
- Lingerie, wedding dresses
Nets knit description, properties and example
- Constructed on a Raschel knitting machine using spun or textured yarns.
- Poor dimensional stability, durable, sheer
- Veils, fishnet stockings
True felt description, properties and example
- Web is laid out and pressed with rollers
- Good insulator, strong, resilient, poor drape
- Coats, furnishings
Needle felt description, properties and example
- Web of fibres is laid out and the hot-barbed needles repeatedly matte the fibres together
- Inelastic, lightweight, resilient
- Carpet underlay, wadding
Chemical bonding
- Fibres are sprayed lightly with adhesive and dried
- Absorbent, lightweight
- Chux
Thermo bonding
- Web of synthetic fibres are passed through heated rollers
- Cheap, washable
- Interfacing, patternmaking
Mechanical bonding
- Web of synthetic fibres are passed through a needle loom to entangle them, then immersed into hot water, shrinking it
- Strong, resilient, flexible
- Stuffed toys, interlining
Staple fibre
Non-continuous fibre - cotton, wool
Filament fibre
Long continuous lengths - silk, nylon, polyester
Woolen spun yarns
- Lighter, airy –> have air pockets
Worsted spun yarns
- Heavier, even –> stronger and more durable
Cotton properties
- Poor drape, relatively strong, highly absorbent, inelastic
Wool properties
- Exceptional drape, weak strength, extremely absorbent, excellent elastic recovery
Polyester properties
- Good drape, relatively strong, poor absorbency, relatively elastic
