This document summarizes a student project that aims to develop fabric from Calotropis fibres blended with organic cotton. It identifies problems with wool production such as environmental pollution, animal welfare issues, and high costs. The project proposes extracting fibers from the Calotropis plant stem using a retting method, blending the fibers with organic cotton in a 1:1 ratio, forming them into a web, spinning yarn via open-end spinning, and making fabric. Literature on Calotropis fiber extraction techniques and properties, as well as environmental impacts of wool and qualities of cotton, support this approach. The methodology section outlines the fiber extraction, blending, web formation, yarn production, and fabric making steps.

2. Problem Identification
Problems In Wool Production
• Wool has a high environmental cost in terms of pollution, biodiversity loss,
land use and greenhouse gas emissions.
• Animal welfare suffers during shearing and short-term acute stress happens.
• Wool is expensive because its natural resource.

3. Problem Identification
Solution - - Calotropis and organic cotton blended fabric
• Calotropis Fibre - The hollowness in the fibre creates air pockets within the
cloth, making it lightweight and adding thermal-regulating properties. Its has
inexpensive extraction technique.
• Organic Cotton - They are non toxic, hypoallergic and also softens the fabric.

5. Reason For Selection Of Calotrophis Fibres
• Abundant
• Easily available and evergreen
• Grow in water scary areas
• Requires no fertilizers
• Potential to process into fibres
• Strong and durable
• Thermal regulating
• Abrasion resistant
• Simple extraction techniques

6. S8 PROJECT WORK II - ZEROTH REVIEW
• The retting method is used to remove the fibre from the stem.
• Calotropis and organic cotton fibres are blended in a 1:1 ratio.
• The extracted fibres are randomly laid into a web.
• To produce yarn, the open end spinning technique is used.
• Yarns are made into a fabric.
