Pina (Pineapple Fibre)  
     
     
 

Pina (Pineapple fiber) is extracted from the leaves of the pineapple plant, Ananas comosus (Linn) Merr.  Pineapple fiber is considered to be more delicate in texture than any other vegetable fiber.  About 60 cm long, white and creamy and lustrous as silk, it easily takes and retains dyes.  Numerous tests in Brazil, Florida, India and the Philippines have shown its exceptional resistance to salt, vapor and traction.  Pineapple fiber has also been processed into paper of remarkable thinness, smoothness and pliability.

Pina fiber can be extracted by hand-scraping, decortications or retting. However, it is only by hand-scraping that good quality fibers are produced for hand weaving. 

 

Chemical Composition of Pina (Pineapple fibre):      

 

It has been found that pina consists of following chemical entities

        

  • Holocellulose 87.56%,

  • Alpha-cellulose–78.11%,

  • Hemicellulose– 9.45%,

  • Lignin – 4.78%.

This composition gives the thermoplastic composite for construction application. Apart from this dietary fibre is also of great importance for commercial purposes.

 

Uses:

 

Hand-scraped pina fiber is hand woven into fabric.  The plain woven fabrics are transformed into intricately-designed and luxurious fabrics, garments and novelty items by hand embroiderers of Lumban, Laguna and Taal, Batangas.  

 

The weavers also revived the production of “sinuksok or pinili”, pina cloth with inlaid design.  Today, pina weavers are also into the production of piña seda cloth (pina fiber blended with silk).

 

The much sought after piña fabric is converted into valuable items such as Barong Tagalog, kimona, panuelo, vestments, table linen, pillow cases, gowns, shawls, fans and other items.  Noted couturiers in the local fashion scene are using the fabric for their creations for fashion shows here and abroad.

 

Decorticated piña fiber is blended with polyester and used for textile production through the mechanized process.  Other application of deco piña is for handmade paper.

 

Advantages:

  • Can be added with other allied fibers to improve their quality and application

  • Zero waste management

  • Eco safe, and rapid technology

  • Employment opportunity for rural population
