Objective: The objective of this lab manual is to provide students with an understanding of yarn and fabric particulars of different Bedford cord weave structures. This lab manual will cover the graphical presentation and weaving plans for various Bedford cord weave structures. At the end of this lab, students will be able to analyze and identify different Bedford cord weave structures.
Materials Required:
- Different types of yarns
- Different types of fabrics
- Microscope
- Measuring tape
- Weaving machine
- Graph paper
- Pencil
- Eraser
Procedure:
- Introduction: Start the lab session by giving a brief introduction about Bedford cord 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 under a microscope. 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 under a microscope. 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 Bedford cord weave structures. b. Analyze each sample under a microscope. c. Observe the interlacing pattern of each Bedford cord weave structure. d. Draw the weaving plan for each Bedford cord weave structure on graph paper. e. Label the warp and weft yarns. f. Record the observations.
- Comparison of Bedford Cord Weave Structures: a. Compare the observations and weaving plans of different Bedford cord weave structures. b. Analyze the differences and similarities between each Bedford cord weave structure. c. Record the observations in a table.
- Conclusion: a. Summarize the observations and findings. b. Discuss the importance of Bedford cord weave structures in the textile industry. c. Provide recommendations for future research.
Safety Precautions:
- Handle the microscope with care.
- Do not touch the lens with fingers.
- Use the weaving machine under the supervision of the lab instructor.
- Wear safety glasses while using the weaving machine.
