Characterization of a Bamboo Cellulose-Activated Carbon Filament and Resin

In the constant search for sustainable and eco-friendly solutions in the materials industry, bamboo cellulose (BC) has emerged as a promising raw material. In this context, combining BC with coconut shell activated carbon (CAC) and anionic resin (AR) has become an area of growing research interest. At room temperature (16.20 °C), BC is mixed with CAC, stirred, and AR is added, forming a homogeneous viscous solution of two blends, M1 (10% BC, 2% CAC, 88% AR) and M2 (15% BC, 2% CAC, 83% AR). It is placed inside a polyester (PET) extruder with a 10 mL capacity. By applying manual force, it is extruded through a 1 mm orifice, resulting in a dense bamboo cellulose filament (BCF) with a titer (T) of 151.18 Denier (g/m) (CV = 7.425) for M1 and 140.89 Denier (g/m) for M2 at 23.80 °C. It is then allowed to rest for 60 min, and the results are analyzed using Past Four software, indicating that the data are standard with a 95% reliability (P > 0.05). The findings suggest that the properties improve in terms of double recovery (DR), ranging from a maximum of 170 degrees to a minimum of 145 degrees (CV = 7.093) within a maximum range of 180 degrees. Maximum elongation (ME) ranges from a maximum of 131.9% to a minimum of 60.2% (CV = 50.665). Maximum strength (MS) ranges from a maximum of 1.59N to a minimum of 0.95N (CV = 35.92). Vertical absorption (WP) ranges from a maximum of 3 mm to a minimum of 2 mm (CV = 25.44). In conclusion, when using the M1 blend (10% BC, 2% CAC, 88% AR), all variables exhibit excellent properties in the order of DR, ME, MS, and WP, making it suitable for various applications.
