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






2. 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...






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






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






5. 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.






6. 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






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






8. 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.






9. 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






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






11. 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






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. 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.






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






15. 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






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






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






18. 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






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






20. Zippers - buttons - Velcro - glue - ties.






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






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






23. Warp knitting and weft knitting.






24. 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.






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






26. 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...






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