DESIGN AND TECHNOLOGY: FASHION AND TEXTILES 7562/1 Paper 1 Technical Principles Mark scheme

DESIGN AND TECHNOLOGY: FASHION AND TEXTILES 7562/1 Paper 1 Technical Principles Mark scheme June 2023 Version: 1.0 Final *236A7562/1/MS* Mark schemes are prepared by the Lead Assessment Writer and considered, together with the relevant questions, by a panel of subject teachers. This mark scheme includes any amendments made at the standardisation events which all associates participate in and is the scheme which was used by them in this examination. The standardisation process ensures that the mark scheme covers the students’ responses to questions and that every associate understands and applies it in the same correct way. As preparation for standardisation each associate analyses a number of students’ scripts. Alternative answers not already covered by the mark scheme are discussed and legislated for. If, after the standardisation process, associates encounter unusual answers which have not been raised they are required to refer these to the Lead Examiner. It must be stressed that a mark scheme is a working document, in many cases further developed and expanded on the basis of students’ reactions to a particular paper. Assumptions about future mark schemes on the basis of one year’s document should be avoided; whilst the guiding principles of assessment remain constant, details will change, depending on the content of a particular examination paper.

The descriptor for the level shows the average performance for the level. There are marks in each level. Before you apply the mark scheme to a student’s answer read through the answer and annotate it (as instructed) to show the qualities that are being looked for. You can then apply the mark scheme. Step 1 Determine a level Start at the lowest level of the mark scheme and use it as a ladder to see whether the answer meets the descriptor for that level. The descriptor for the level indicates the different qualities that might be seen in the student’s answer for that level. If it meets the lowest level then go to the next one and decide if it meets this level, and so on, until you have a match between the level descriptor and the answer. With practice and familiarity you will find that for better answers you will be able to quickly skip through the lower levels of the mark scheme. When assigning a level you should look at the overall quality of the answer and not look to pick holes in small and specific parts of the answer where the student has not performed quite as well as the rest. If the answer covers different aspects of different levels of the mark scheme you should use a best fit approach for defining the level and then use the variability of the response to help decide the mark within the level, ie if the response is predominantly level 3 with a small amount of level 4 material it would be placed in level 3 but be awarded a mark near the top of the level because of the level 4 content. Step 2 Determine a mark Once you have assigned a level you need to decide on the mark. The descriptors on how to allocate marks can help with this. The exemplar materials used during standardisation will help. There will be an answer in the standardising materials which will correspond with each level of the mark scheme. This answer will have been awarded a mark by the Lead Examiner. You can compare the student’s answer with the example to determine if it is the same standard, better or worse than the example. You can then use this to allocate a mark for the answer based on the Lead Examiner’s mark on the example. You may well need to read back through the answer as you apply the mark scheme to clarify points and assure yourself that the level and the mark are appropriate. Indicative content in the mark scheme is provided as a guide for examiners. It is not intended to be exhaustive and you must credit other valid points. Students do not have to cover all of the points mentioned in the Indicative content to reach the highest level of the mark scheme. An answer which contains nothing of relevance to the question must be awarded no marks. Glossary for maths If a student uses a method which is not explicitly covered by the mark scheme the same principles of marking should be applied. Credit should be given to any valid methods. Examiners should seek advice from their senior examiner if in any doubt. [a, b] Accept values between a and b inclusive. For π Accept values in the range [3.14, 3.142] Their Accept an answer from the candidate if it has been inaccurately calculated but is subsequently used in a further stage of the question. Questions which do not ask students to show working As a general principle, a correct response is awarded full marks. Qu Part Marking Guidance Total marks AO 01 1 Describe the structure of twill weave fabric. Indicative content Twill weave fabric: • weft yarns travel across the width of the fabric • warp yarns travels the length of the fabric/fixed in the loom • weft yarns run over and under warp yarns at regular intervals eg 2/2, 2/1 • interlacing of the yarns moves along one/is offset on subsequent rows • raised diagonal lines are created on the surface of the fabric. Award any other valid responses. Students may include diagrams to explain their answer, accept a plan drawing. Award a maximum of 2 marks for a correct diagram with no labels. Accept 2/2 or any other twill structure. This question is about the structure of twill weave fabric, and not its properties. 1 mark per correct point up to a maximum of 3 marks. 3 marks AO4 1a Qu Part Marking Guidance Total marks AO 01 2 Describe the structure of weft knitted fabric. Indicative content Weft knitted fabric: • one yarn is used • courses travel across the width of the fabric • loops travelling the vertical length of the fabric are called a wale • each horizontal row interlocks with the previous row • creating a looped structure. Award any other valid responses. Students may include diagrams to explain their answer. Award a maximum of 2 marks for a correct diagram with no labels; additional information is required for more marks. 1 mark per correct point up to a maximum of 3 marks. 3 marks AO4 1a Qu Part Marking Guidance Total marks AO Ct w 02 Explain how smart materials can improve the performance of sportswear. You should include specific examples of smart materials in your answer. 6 marks AO4 1c Indicative content • Phase change materials – PCMs have the ability to change from solid to a softer state, allowing heat to transfer away from the body. Outlast® for example, traps wax in microcapsules in the fabric, as the skin gets hot, the heat is absorbed into the soft wax, allowing it to escape. This keeps the wearer at an optimal temperature, improving comfort. • Stomatex® – is a breathable neoprene material, that keeps the wearer dry and regulates body temperature. Domed chambers on the fabric surface trap warm air from the body and release this air through tiny pores in the chamber at a controlled rate. Stomatex® flexes with movement and reacts with the users’ level of physical activity. • Thermochromic – this material can change colour in response to high temperature. Materials are impregnated with liquid crystal; and in response to changes in temperature, change colour alerting the wearer to possible overheating. • Photochromic dyes – responds to UV light by changing colour, to visually warm the wearer the light levels are potentially dangerous. • Fastskin® – inspired by biomimetics, this material imitates the skin texture of a shark, the varying ridges knitted into the fabric respond to movement. Made for swimwear, the wearer becomes more streamlined in water. • Nanotechnology – self-cleaning fabrics have been developed that react to sunlight, degrading organic matter when exposed to light. These materials keep clean and fresher for longer. • Photoluminescence – material that absorbs UV or daylight and re-emits in the dark as a light source. • Corpo Nove shirt – a prototype product woven with titanium. Creases in the fabric are released in the presence of heat, allowing the garment to return to its original shape. Do not accept microencapsulated, Coolmax®, Gore-tex®. Award any other valid responses Qu Part Marking Guidance Total marks AO 03 Special effect metallic threads can be added to fabrics at different stages of production. Give two different ways metallic threads can be added to fabrics. Indicative content • Metallic threads can be spun into the yarn at the spinning stage. • They can be woven into the fabric structure. • Yarns which incorporate a metallic thread can be knitted into a fabric. • They can be stitched or embroidered onto the fabric surface. Award any other valid responses. 1 mark per correct point up to a maximum of 2 marks. 2 marks AO4 1b Qu Part Marking Guidance Total marks AO 04 A retailer has different offers on garments as shown in Table 1.

The information given is accurate, demonstrating a clear understanding of the different types of systems and the student has related these to the demand for fast changes in fashion. There may be a slight lack of detail at the low end of the mark band, but the information is generally correct and does not detract from the quality of the response. 4–6 Good description of different garment manufacturing marks systems used in fashion production. In this mark band a few systems are explained, which are generally appropriate and meet the demand for fast changes in fashion. The information given is mostly accurate, demonstrating some understanding of the different types of systems, and the student may have attempted to relate these to the demand for fast changes in fashion. There is likely to be a lack of detail at the low end of the mark band, but the information given is mostly correct. 1–3 Basic description of different garment manufacturing marks systems used in fashion production. In this mark band, there is a limited range of systems, which are not always appropriate or meet the demand for fast changes in fashion. The information lacks accuracy, demonstrating little or no understanding of the different types of systems, and there is limited awareness of the relationship to the demand for fast changes in fashion. There is a lack of understanding at the low end of the mark band, with some confusion and inaccuracies. 0 marks No response or nothing worthy of credit. Indicative content • QRM – Quick response manufacturing systems. These focus on rapid design and manufacture of garments, shortening lead times so that products reach stores quickly to meet demands for fashion trends. • PPC – Planning, production and control systems are concerned with planning and controlling all aspects of manufacturing. This includes scheduling machines and processes, tracking products, and coordinating stock levels with supply chains to ensure efficient and smooth production. • JIT – Just in Time systems allow manufacturers to order fabrics and components as needed.
