Development of Prototype Textile Products From Kluai Khai–cotton Blended Fibers for Commercial Application

The study investigated the utilization of banana sheath waste after harvest. The results showed that fibers extracted from banana sheaths can be effectively blended with cotton fibers. Based on the analysis of the physical and chemical properties of the fibers, Pattern 5 (yarn size No. 10 with 10% of Kluai Khai fiber and 90% of cotton blended fibers) and Pattern 6 (yarn size No. 10 with 15% of Kluai Khai fiber and 85% of cotton blended fibers) exhibited the highest levels of lignin, hemicellulose, cellulose, and ash—components that contribute to fiber strength due to their crystalline structure. In the development of woven fabric products combining banana and cotton fibers, Pattern 2 (yarn size No. 5 with 10% of Kluai Khai fiber and 90% of cotton blended fibers) demonstrated the highest strength and durability, with statistical at a significance level of 0.05 (p < 0.05). Nevertheless, patterns 5 and 6 were also suitable for crafting household items, especially considering their higher banana fiber content (10% and 15%), which effectively reduces agricultural waste. Prototype products developed from patterns 5 and 6 included hats, bags, and tablecloths. These products received high to very high satisfaction ratings from users (average scores ranging from 4.02 to 4.55) and showed the lowest levels of heavy metals, with statistical at a significance level of 0.05 (p < 0.05). Upon completion of the research process, a knowledge manual was created to support further development among target groups such as the Ban Mudmee weaving group and the Pangwai Forest Community Enterprise. Additional recommendations include offering products in various sizes, improving fabric softness, and expanding the range of fabric colors to enhance consumer appeal.
