Abstract

In this study, bamboo activated charcoal was mixed with acrylic resin in various proportions and deposited on poly-ethylene terephthalate (PET) non-woven fabrics. A series of characterizations were carried out to estimate the performances of PET non-woven fabrics such as far infrared ray emission, heat retention, negative ions, deodorization of ammonia gas and tenacity. The results obtained indicate that the temperature difference on the surface of treated non-woven fabrics after exposure to a halogen lamp was between 4.28 to 8.26°C. The test for negative ions demonstrated that the concentration of negative ions released from treated non-woven fabrics was 420 to 630 ions/cm3. The deodorization rate of the treated non-woven fabrics was found to be between 85 to 92% and the rate was the same for 5 and 10 g/L of bamboo activated charcoal addition. An increase in resin concentration increased the abrasion strength and tensile strength; and reduced the tear strength of the treated non-woven fabrics. The bamboo activated charcoal concentration exhibited no effect on the physical properties of the treated non-woven fabrics.

Key words: Poly-ethylene terephthalate (PET), non-woven fabrics, bamboo activated charcoal, far infrared ray, negative ions, deodorization.
