2. outline Introduction Pina fiber steps for fiber extraction Advantages of pinna Limitations pinna application

3. Introduction In this project, we have made attempt to provide a good deal of information about the methodology of producing yarns from pineapple leaves to form a blend with a synthetic fibres for making fabric and its related value added products

4. What is pina fiber? Piña is a fiber made from the leaves of a pineapple plant and is commonly used in the Philippines. It is sometimes combined with silk or polyester to create a textile fabric. Piña's name comes from the Spanish word piña which literally means Pineapple. piña fabric is hand loomed by only a few weavers, it is very precious and scarce, which also makes it expensive.

6. Steps for Fibre Extraction The leaves are detached from the pineapple plant Take off the side thorns Soaked in water for some days Scrapping with a broken plate to remove the exterior layer After scrapping, the fibers are then removed wash the fibers under running water dry carding to prevent knotting

7. Advantages of pina Biodegradable in nature and processed residual material bought into effective use makes it environment friendly and toxic free. Has high tensile and flexural strength helps in making products sufficient strength. Best substitute to synthetic material in tensile, density, fineness and cohesive nature of fiber makes it better suitable for composite manufacturing. Raw material availability is in abundance. Hydrophilicity nature makes it convenient for dye take-up and retentivity. Transmits low thermal value thereby making it a good thermal insulator.

8. Limitations of pina Undergoes quick bio-degradation. Continuous itching of outer layer even after chemical modification is complete. Tensile strength reduces drastically with ageing. Time consuming process for extraction of fiber material. Not stable to chemical agencies. With higher mix ratio in composite the water absorbency increases making it unfit for civil construction works.

9. Nylon Nylon is made from polyamide fiber , derived from a diamine and a dicarboxylic acid that is formed into thin strands and woven into fabric. It is a synthetic fabric that utilizes the chemical by-products of coal, petroleum and agricultural products. Synthetic polymers give nylon fabrics a low absorbency rate ideal for swimwear, stockings and athletic clothing. Characteristics of Nylon Fiber Exceptionally strong, Elastic , Abrasion resistant , Lustrous, Easy to wash ,Resistant to damage from oil and many chemicals ,Can be precolored or dyed in wide range of colors ,Resilient ,Low in moisture absorbency, Filament yarns provide smooth, soft, long-lasting fabrics, Spun yarns lend fabrics light weight and warmth Weaving and Warp Knitting High fiber modulus – minimizes yarn distortion possible during winding, warping, knitting, and weaving processes – minimizes barré and streaks during dyeing 

10. Nylon Wide operating window for heat setting, dyeing, and processing, this is especially important for fabric combinations with spandex Very good resistance to photo degradation Good dye light-fastness Good dye wet-fastness   Disadvantages of NYLON FIBER: the fabric melts when exposed to high heat, can be uncomfortable to wear next to skin, and absorbs oil and grease. But these disadvantages are less seen when nylon fibers are blended with pinna fibers

12. . Advantages of Blending: When two different types of fibres are blended, the properties of these two different fibres are synergized. For instance, in the blend of cotton and polyester, cotton provides the absorbency and polyester provides the strength. Blending is done to produce a fabric, which is economical by combining the aesthetic comfort properties of the natural fibres with the easy care and strength properties of synthetic fibers. Blending also helps to provide the fabric’s light weight with all desirable characteristics. Improving spinning, weaving and finishing efficiency and the uniformity of product.

13. Twisting of Yarns yarns , plies , or strands are twisted or braided together into a larger and stronger form. Ropes have tensile strength and so can be used for dragging and lifting, but are too flexible to provide compressive strength . As a result, they cannot be used for pushing or similar compressive applications

14. Various uses of Pina -polyester fiber piña fabric is converted into valuable items such as Barong Tagalog, kimona , panuelo , vestments, table linen, pillow cases, gowns, shawls, fans and other items. is converted into valuable items such as Barong Barong Barong Tagalog Tagalog ki kimono mono vestments Table linen Table linen

15. ADVANTAGE OF PINA FIBER & CLOTH The fabric has a natural gloss similar to silk, and is better in quality. This gloss protects the fibers and as a result, piña does not require any treatment with toxic chemicals. It is easy to wash and care for; no dry cleaning required! Piña cloth is wear-resistant It is an ideal eco-textile for clothing Pina fiber Long, fine, lustrous.

16. Conclusion The special properties of these fibers like their high strength, low elongation and good luster can be combine beneficial to produce novelty fabrics which will exhibit unparalleled properties. Long fiber lengths and high fiber weights make it difficult to be blended with nylon fiber
