7. 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






8. 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.






9. Warp knitting and weft knitting.

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






14. 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.






15. 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






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






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






18. 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






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






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






21. 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






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






23. 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...






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






25. 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.






26. Zippers - buttons - Velcro - glue - ties.






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