Physical and Tensile Properties of Handmade Sida rhombifolia Paper

Abstract

This study focuses on the production and characterization of biodegradable handmade paper from the Sida rhombifolia plant (SRP) cellulose. Sida rhombifolia plant is a seasonal plant that grows in the equatorial and tropical climates. The studies carried out on this SRP were aimed at investigating the methods required for the production of handmade paper from SRP plant and also at determining the tensile strength. Four specimens of SRP paper of different additive labels S0 (no additive), S1 (starch and KOH), S2 (starch), and S3 (Foska liquid glue) were produced using the Kraft method. Tensile properties (stress at break, elongation at break, and Young’s modulus), the rate of water absorption, and the rate of moisture absorption were carried out. Results showed that the addition of potassium hydroxide considerably reduces Young’s modulus of SRP handmade paper (S1) while the Foska liquid glue (S3) significantly improves it. In addition, the addition of potassium hydroxide and Foska liquid substantially improves the water absorption properties of the paper S2 and S3, respectively. The adhesive liquid creates more porosity and consequently increases the absorption of water. The addition of potassium hydroxide and Foska liquid significantly embedded the rate of moisture absorption. From the results obtained, it can be concluded that the paper S3 can be used as packaging paper since it has better mechanical properties and moisture absorption.

Material Properties of Traditional Handmade Paper Samples Fabricated from Cellulosic Fiber of Lokta Bushes

“…In paper making, low apparent density (high porosity) arises due to the long and stiff fibers, insufficient refining, absence of fillers and fines, insufficient or no calendaring, and their combinations, which could explain the low apparent density of handmade papers. Low apparent density in the range of 0.2–0.5 g/cm 3 was also reported in laboratory-made handmade paper samples. ,, …”

“…Low apparent density in the range of 0.2–0.5 g/cm 3 was also reported in laboratory-made handmade paper samples. 6 , 10 , 11 …”

“…Low apparent density in the range of 0.2−0.5 g/cm 3 was also reported in laboratorymade handmade paper samples. 6,10,11 Equilibrium moisture content (EMC) of the paper samples ranged from ∼4.3% (P1) to 7.3% (P8). Similar values of moisture content were reported for cellulose-based paper sheet.…”

“…The paper sheets are fabricated from woody or non-woody parts of different plant species following mechanical and chemical methods of fiber processing or their combination. 6 − 11 A number of factors such as length and strength of individual fiber, organization of fiber, degree of cross-linking and bonding, chemical composition of fiber and processing parameters, extent of fibrillation, fines, and crill content determine the strength of a paper sheet. 12 − 18 The long fibers can form more contact points than short fibers, eventually leading to the paper of higher strength.…”

“…Therefore, based on physical properties, fiber characteristics, and chemical composition, it was concluded that S. grossus , C. rotundus , and T. angustifolia are suitable candidates for handmade papermaking. Similarly, Mejouyo et al (2020) discussed the production and characterization of biodegradable handmade paper obtained from Sida rhombifolia plant cellulose. The paper was prepared by a traditional method called “Kraft method,” and thereafter, physical characterization was evaluated, viz ., tensile properties (Young’s modulus, elongation at break, and stress at break), water, moisture absorption rate, etc.…”
