Chapter 7 other types of textiles Flashcards
7 Methods of producing of textiles:
- non woven
- felt
- bonded
- laminated
- lace
- embroidery
- tufted fabrics
what are the 2 major textile production method?
weaving and knitted
what are the benefits of nonwovens
cheap, disposable products for medicine, hygiene, food. durable, no yarns are present, basic materials
Manufacturing methods for non-woven’s?
Staple fiber web, drylaid, wetlaid, spunlaid system
Drylaid system:
fibers manipulated while in a dry state
Wetlaid system:
fibers manipulated while in a wet state
Spunlaid system:
thermoplastic fibers blow as they are extruded
what is the bonding process determined by?
fiber content,
- web formation method, and
-intended end use
Mechanical Bonding:
Fibers entangled or stitched to hold them in place and add strength
what are the 5 Different methods of mechanical bonding
Needle punching, Spun lacing or hydroentangling, Stitch , thermal and chemical bonding
Needle punching
needle entangle staple fiber webs
Spun lacing or hydroentangling
water entangles fibers
Stitch bonding:
chain stitch holds the web together.
Thermal bonding
heat fuses thermoplastic fibers. Fuses polymer fibers that are still in semi solid stage
chemical bonding:
resins and binders adhere to fibers. Chemicals used affect properties.
Carded-Web Nonwovens
forming a web of fibers and then bonding the fibers
