Objective: The objective of this lab manual is to provide students with an understanding of yarn and fabric particulars of different backed fabric weave structures. This lab manual will cover the graphical presentation and weaving plans for various backed fabric weave structures. At the end of this lab, students will be able to analyze and identify different backed fabric weave structures.
Materials Required:
- Different types of yarns
- Different types of fabrics
- Measuring tape
- Weaving machine
- Graph paper
- Pencil
- Eraser
- Backing material
Procedure:
- Introduction: Start the lab session by giving a brief introduction about backed fabric weave structures and their importance in the textile industry.
- Analysis of Yarn Particulars: a. Take a few samples of different types of yarns. b. Analyze each yarn sample. c. Observe the fiber length, fiber strength, and fiber density of each yarn sample. d. Record the observations in a table.
- Analysis of Fabric Particulars: a. Take a few samples of different types of fabrics. b. Analyze each fabric sample. c. Observe the fabric density, fabric strength, and fabric texture of each fabric sample. d. Record the observations in a table.
- Graphical Presentation: a. Draw a graph for each yarn and fabric sample. b. Use the observations from step 2 and 3 to plot the graph. c. Label the x-axis and y-axis with appropriate units. d. Interpret the graph and record the observations.
- Weaving Plans: a. Take a few samples of different backed fabric weave structures. b. Analyze each sample. c. Observe the interlacing pattern of each backed fabric weave structure. d. Draw the weaving plan for each backed fabric weave structure on graph paper. e. Label the warp and weft yarns for both the layers. f. Record the observations.
- Backing Material: a. Take a few samples of different backing materials. b. Analyze each backing material sample. c. Observe the strength and texture of each backing material sample. d. Record the observations in a table.
- Comparison of Backed Fabric Weave Structures: a. Compare the observations and weaving plans of different backed fabric weave structures. b. Analyze the differences and similarities between each backed fabric weave structure. c. Record the observations in a table.
- Conclusion: a. Summarize the observations and findings. b. Discuss the importance of backed fabric weave structures in the textile industry. c. Provide recommendations for future research.
Safety Precautions:
- Use the weaving machine under the supervision of the lab instructor.
Conclusion: In this lab manual, students learned about the analysis of yarn and fabric particulars of different backed fabric weave structures. The lab covered the graphical presentation and weaving plans for various backed fabric weave structures. By the end of this lab, students will be able to analyze and identify different backed fabric weave structures. The lab also emphasized the importance of backed fabric weave structures in the textile industry.
