Physico-chemical characteristics of a seed fiber arised from Pergularia Tomentosa L.

Characterization of industrial discarded novel Cymbopogon flexuosus stem fiber: A potential replacement for synthetic fiber

“…The higher cellulose content in the fiber guarantees higher tensile strength and modulus of elasticity [60]. The CFS fiber showed high cellulose content of 68.13%, which is higher than that of G. tilifolia (62.8%) [42], C. grandis (62.35%) [45], P. juliflora bark (61.65%) [40], Saharan aloe vera (60.2%) [22], C. dichotoma (59.7%) [34], A. hystrix (59.54%) [52], areca palm leaf stalk (57.49%) [68], seagrass (57%) [28], Ficus religiosa tree root (55.58%) [58], Napier grass strands (47.12%) [49], alfa (45.4%) [74], Althaea officinalis L (44.6%) [50], Arundo donax (43.2%) [51], and Pergularia tomentosa L seed fiber (43.8%) [56]. The CFS fiber cellulose content was near to that of other natural fibers such as Borassus fruit (68.94%) [8], Cyperus pangorei (68.5%) [47], Perotis indica (68.4%) [44], aerial roots of banyan tree (67.32%) [27], Rhectophyllum camerunense (68.2%) [8], Acacia arabica (68.10%) [8], and Acacia leucophloea (68.09%) [69].…”

“…While manufacturing polymer composite structure, fiber with low wax content will establish a good bonding capacity [30]. The wax content of sisal (2%) [28], alfa (2%) [28], P. tomentosa L seed fiber (1.88%) [56], aerial roots of banyan tree (0.81%) [27], hemp (0.8%) [28], kenaf (0.8%) [28], C. grandis (0.79%) [16], T. populnea (0.76%) [11], Ficus religiosa tree root (0.72%) [58], Areca palm leaf stalk (0.71%) [68], T. procumbens (0.71%) [24], P. juliflora bark (0.61%) [40], Acacia planifrons (0.57%) [43], and D. cinerea (0.57%) [77], which is comparatively higher than the CFS fiber wax content (0.53%). A similar bonding effect was also observed with moisture content present in the fiber.…”

“…Amorphous nature was reduced due to ash content in the fiber [45]. The CFS fiber had 4.81% ash content, which was higher than C. grandis (4.38%) [16], P. indica (4.32%) [44], mendong grass (4.2%) [48], S. rhombifolia (4.07%) [60], A. planifrons (4.06%) [43], aerial roots of banyan tree (3.96%) [27], red banana peduncle (2.79%) [23], P. tomentosa L seed fiber (2.74%) [56], A. officinalis L (2.3%) [50], A. donax (1.9%) [51], T. populnea (1.80%) [11], and Areca palm leaf stalk (1.43%) [68]. CFS fiber chemical weight % were compared with those obtained for other natural fibers (Table 1).…”

“…When hemicellulose content in the fiber was increased, an adverse effect on the strength of the fiber was observed, which was due to disintegration of cellulose microfibrils [11]. The CFS fiber had 11.56% hemicelluloses content, which was comparatively lower than alfa (38.5%) [28], seagrass 1223S (38%) [28], mulberry barks (37.38%) [70], Napier grass strands (31.27%) [49], bamboo (30%) [76], C. dichotoma (23.6%) [34], G. tilifolia (21.2%) [42], A. donax (20.5%) [51], mendong grass (20.2%) [8], Heteropogon contortus (19.34%) [64], areca palm leaf stalk (18.34%) [68], Sida cordifolia (17.63%) [46], P. juliflora bark (16.14%) [40], P. tomentosa L seed fiber (16%) [56], S. rhombifolia (15.43%) [60], Borassus fruit (14.03%) [8], Saharan aloe vera (14.2%) [22], root of Ficus religiosa tree (13.86%) [58], Salago fiber (13.6%) [65], A. leucophloea (13.60%) [69], A. officinalis L (13.5%) [50], aerial roots of banyan tree (13.46%) [27], C. grandis (13.42%) [16], Dichrostachys cinerea (13.08%) [59], T. populnea (12.64%) [11], Manicaria saccifera palm (12%) [57], and A. hystrix (11.35%) [52]. Higher lignin content prevents microbial attack in the fiber, but at the same time, it shows a negative influence on fiber structure and its morphology [59].…”

Cationic dye removal using Pergularia tomentosa L. fruit: kinetics and isotherm characteristics using classical and advanced models

“…They are exclusively restricted to this kind of application. Sakji et al and Sebeia et al investigated the physicochemical characteristics and the adsorption capacity of the seed fibers of Pergularia tomentosa L. [19,20]. The adsorption energy was not accurately evaluated since empirical models were used.…”
