To realize the similarities and differences between domestic and industrial tools and machines. To become familiar with and be able to use a variety of textile techniques. To be able to select appropriate tools for different tasks. To use tools and equipment safely and accurately. 2 of 21 © Boardworks Ltd 2005 What do you know? 3 of 21 © Boardworks Ltd 2005 Basic equipment – scissors Scissors or shears are used to cut fabric and thread. They Pinking shears at first come in a range of sizes, from glance look like scissors. very large to small embroidery The zigzag blade can be scissors. When carrying used to limit fraying or to scissors, you should hold them leave a decorative edge. by the blade to avoid injury. 4 of 21 © Boardworks Ltd 2005 Cutting When cutting out fabric it is important that you lay it out in the correct manner – selvedge edges together. Ensure that balance marks or notches are included – it is sometimes helpful if you cut these out rather than snip into the fabric. This makes them easier to see when constructing your product. Keep the pattern pieces attached to the fabric to enable you to locate the pieces. 5 of 21 © Boardworks Ltd 2005 Basic equipment – tape measures and tailor’s chalk Tape measures are ideal for use when making clothes as they can go around the body. Tailor’s chalk has a soapy consistency and is available in many different colours to suit different fabrics. It is used to draw around patterns and mark darts, button holes and where pockets are placed. 6 of 21 © Boardworks Ltd 2005 Marking out Your fabric should be laid out right sides together for you to make any marks on it. You can either pin your pattern to the fabric or weigh it down using fabric weights. Tailor’s chalk is then used to mark around the pattern. Balance marks/notches, darts and pocket placements, etc. should be marked at this stage. You may then cut around the pattern, ensuring notches and balance marks are cut out in a Vshape. 7 of 21 © Boardworks Ltd 2005 Basic equipment – pins and needles Pins are used to hold two pieces of fabric together. They are used prior to tacking to hold things in place. They are also used to attach the pattern to the fabric. There are two main types of needle: hand needles and machine needles. Hand needles are available in many sizes. These sizes can determine the length, thickness and size of the eye. 8 of 21 © Boardworks Ltd 2005 Pinning When pinning a pattern to fabric, insert the pins within the seam allowance. This will ensure that no pin holes are visible in the garment/textile product. This is particularly important if you are using a waterproof fabric. By doing this you will also reduce any snags in the fabric. Start pinning in the corners of the pattern, then work your way along. 9 of 21 © Boardworks Ltd 2005 Pinning Prior to tacking, pins should be used to attach the fabric pieces together. There are two ways to pin fabric together: Pin perpendicular to the seam, as this allows you to sew over the pins and remove them after you have done so. Pin parallel to the seam so that it is possible to remove the pins as you sew towards them. 10 of 21 © Boardworks Ltd 2005 Tacking When all the pieces of the textile item are pinned, they should then be tacked together. Tacking thread is a very thin temporary thread that is easily broken. It should be used as a single strand and it is not necessary to knot the ends. Tacking is done by hand using stitches of 1cm in length. When you have machine stitched your item, remove all tacking thread using a seam ripper. 11 of 21 © Boardworks Ltd 2005 Seams Seams are made when two pieces of fabric are attached together. They are generally 1-1.5cm wide; however, you should always check your pattern. Some patterns do not include a seam allowance – you should check prior to cutting out. How long the stitches are on your seams will depend on the fabric you use. When using a stretchy fabric, a larger stitch should be used. Make sure that you reverse a few stitches at the beginning and end of every seam. This will ensure that the seam does not come loose over time. 12 of 21 © Boardworks Ltd 2005 Hems Hems are normally found on the bottoms of garments or soft furnishings. If you are making a pair of trousers that have turn-ups, you will need to calculate how much turn-up you require and how much hem you want. For a 3cm turn-up with a 1.5cm hem, you would multiply the turn-up length by two and add the 1.5cm hem: 1.5 x 2 + 1.5 = 7.5cm It is also possible to create a false hem on an item. This is often done when skirts or trousers require lengthening and there is not enough hem to do so. Binding tape is attached to the bottom of the fabric and this is then turned up accordingly. This process can also be applied to curtains. 13 of 21 © Boardworks Ltd 2005 Textile machines 14 of 21 © Boardworks Ltd 2005 Sewing machines There are four main types of sewing machines. Standard machines enable you to sew basic stitches, for example to attach pieces of fabric. They are also suitable for doing simple embroidery. They are made up of a machine, pedal and power cable. Overlockers are used to finish off seams and hems of garments. They can also be used as a feature. The overlocker trims the fabric as it sews the seam. 15 of 21 © Boardworks Ltd 2005 Embroidery machines The embroidery machine gives students an ideal opportunity to explore an industrial process. 1. A design is copied using a scanner or created using CAD software. 2. The embroidery machine can be linked directly to a PC or designs can be transferred on a disk. 3. The image is then downloaded onto the machine’s memory and output onto the machine bed, creating a machined logo or image. 16 of 21 © Boardworks Ltd 2005 Knitting and weaving machines Knitting machines can stand alone or be linked to a computer. They can create complex patterns and complete garments. Domestic knitting machines are called flat bed knitting machines. There are many different types of weaving looms that can create a number of different weaves, including plain, satin and twill. In factories, machines such as looms are often controlled by computers. What are the advantages and disadvantages of using these five machines instead of sewing by hand? 17 of 21 © Boardworks Ltd 2005 Heating equipment Irons can be used for ironing, pressing and steaming. Check the label first to see the best temperature to iron at. Ironing will finish the garment off – this is normally the last stage of manufacture but can also be done throughout. Pressing is used when bonding – e.g. attaching interfacing to a piece of fabric. Steaming can be done without actually touching the fabric. It is used on garments made from delicate fabrics. 18 of 21 © Boardworks Ltd 2005 Heating equipment Heat presses are normally used for transfer printing. An image is produced using CAD (computer aided design) and printed out onto the transfer paper. This image is then heat pressed for a number of minutes. Unlike ironing it enables you to heat the whole design at the same time, thus giving a more professional finish. 19 of 21 © Boardworks Ltd 2005 Quiz 20 of 21 © Boardworks Ltd 2005 Key points Key points Scissors and pinking shears are used to cut fabric. A tape measure measures parts of the body and tailor’s chalk temporarily marks the fabric. Pins hold fabrics in place temporarily and needles are used to attach them permanently with thread. The only type of sewing which is not permanent is tacking. Textile machines include sewing machines, overlockers, embroidery machines, knitting machines and weaving looms. These are used in homes and in industry. Ironing is normally the last stage of manufacture. If an item is made from a delicate fabric, a steamer may be used to finish it instead. Irons and heat presses can also be used to transfer images. 21 of 21 © Boardworks Ltd 2005
