1. A thread is looped - twisted or braided to other threads independently from a backing fabric.






2. Made from webs of synthetic fibres bonded together with heat or adhesives. They are cheap to produce by not strong. They are easy to sew - crease resistant - does not fray and are stable when washing and dry cleaning.






3. Bonded- fibre fabrics are made from webs of synthetic fibres bonded together with heat or adhesives.






4. Warp knitting and weft knitting.






5. Strong - drapes well. Used for jeans - jackets and curtains






6. Slightly stretchy and does not ladder. Used for swimwear - underwear and geotextiles






7. During the weaving process - the weft yarn is taken over and underneath the warp yarns with a '________'. For each row being woven - selected warp yarns are either lifted or lowered - creating a passage for the shuttle to pass through with the weft y






8. Is transparent. Exquisite decorative fabric. Can be made from a variety of different fibres (eg. wool - cotton - silk). Can shrink - tears easily.






9. A material made up of a network of natural or artificial fibres formed by knitting - weaving or pressing felt






10. One-off production - needlework and embroideries are sometimes too complex - time and effort mean more to the consumer - meaningful to societies - main source of income to places where money for new technology is not available






11. Fabric glue- creates a simple - straight seam that receives little stress.






12. Made from animal hair or wool fibres matted together. Felt has no strength - drape or elasticity. But it is warm and does not fray - wool felt is expensive. Used for hats - slippers and in handcrafts.






13. Stretchy and comfortable. Used for socks - tshirts and jumpers






14. Used to permanently join two fabrics together using an adhesive resin. In a factory - this could be a flat bed press (used to join short fabric lengths for batch production) and a conveyor press (used for fusing long fabric lengths for mass productio






15. Involves applying a layer of polymer to the surface of the fabric. Teflon coating makes fabrics stain resistant - water repellent and breathable.






16. Knitted fabric consists of consecutive loops - called stitches. As each row progresses - a new loop is pulled through an existing loop. The active stitches are held on a needle until another loop can be passed through them. This process eventually re






17. Most fabrics commonly use a flat seam. This is also fast and cheap. Two fabrics together. Neat finish.






18. Cotton and synthetic fabrics are bleached before dying. this makes it easier to dye pastel shades.






19. Involve an engraved of a raised calender roller that presses a three- dimentional pattern onto a textile. the embossing permanently presses it down to create the embossed effect.






20. Wool felt is a non - woven fabric made from animal hair or wool fibres matted together using moisture - heat and pressure. The fibres are placed all facing one direction - warm water is then poured on top. Then soap is applied and pressure along with






21. Plain weave is strong and hardwearing. Used for fashion and furnishing fabrics.






22. When the shuttle completes passing through the space provided - the position of the warp yarn is again changed and the weft is brought back through in the ____________. This process is continually repeated until the fabric is produced.






23. During weaving - a second yarn is then threaded from side to side - over and under the warp yarns - to make a fabric. This is called a...






24. Zippers - buttons - Velcro - glue - ties.






25. This is the simplest weave - the weft yarn passes over one then underneath one warp yarn at a time. It produces strong - durable fabric for a variety of clothing and furnishing needs.






26. The interlacing of two or more yarns using a loom. Generally - woven fabrics are strong fabrics.






27. To weave the yarns together - the loom is first set up with yarns running lengthwise - from the top to the bottom of the loom.These are called...
