2. Felts- a non-woven fabric made primarily of wool and fused to take advantage of wool’s natural scale structure by the application of heat, moisture and pressure to cause shrinkage and the intermeshing of fibers
3. Basic construction methods -dry process- majority of textile webs -wet process- paper making machines 4. Web formation methods -parallel laid web- all fibers run into same direction, carded- high lengthwise strength low transverse strength -cross laid web- web build up in sandwich fashion, sequence of layers with fiber in opposite direction. strong in both directions 5. needle punched- a web of fibers is fed though a series of barbed needles to entangle layers of fibers. More flexible than bonded fibers durable fabrics- carpet backing, blankets indoor/outdoor carpet insulation materials, felt 6. spun lace- sheets of fiber made by water or air entanglement.No adhesive or binder used. Quilt backing, mattress pad backing, disposable table coverings, disposable dust rags, wash cloths 7. spun bonded- manufactured from synthetic filament fibers, laid down directly from the spinneret in a random arrangement. The application of heat, chemicals or adhesives at points of crossing of the fibers effeclty bonding them together. Uses: interlining, interfacing, backing for carpets, furniture, web, bedding, bagging, maps, road constution, weed reduction in gardens
8. fabric webs- fabrics made directly from fibers usually held together by entangling or bonding and are known as fabric webs.
9. films- synthetic polymers extruded in the form of sheets rather than fibers.
10.foams- are made by incorporating air into an elastic- like a subsrance. Most commonly used substances are rubber and polyurethane. .must be used with backing or covering. Often incorperated into garments or household textiles for its insulation and/or cushioning qualities
1. Yarn- continuous strand of staple of filament fibers, which have been grouped or twisted together to use in fabric structures. Yarn is the link between the fiber and the fabric
2. Spun yarns- yarns made of staple fibers either natural or man made
3. Mono-filament- composed of one strand- durable and allow light to go through
4. Multi-filament- several strands
5. Staple length- fuzzy and have more volume than
