Structural and physical characteristics of theyuccafiber

Abstract

Yucca fiber is a natural cellulose fiber that can be extracted from the Yucca plant leaves by retting. The physical properties of the Yucca fiber are extremely sensitive to the retting conditions. This research was designed to study the effects of chemical retting on the structural and properties of this fiber. Chemical retting was done by soaking the Yucca leaf in 10 to 150 g/l sodium hydroxide concentration at 80 to 100 °C for 60 to 240 min. Fiber characteristics such as fineness, tenacity, functional groups, crystallinity, thermal degradation, and surface morphology were then investigated. The Yucca fibers exhibited high crystallinity (56–66%), high tenacity (36–46 cN/tex), and low linear density (3–5 tex). It was also found that the elementary fiber had a mean diameter of about 1.2 [Formula: see text] and a helical structure of square-shaped spires. The thermogravimetric analysis also indicated that the Yucca fiber had the thermal stability of up to 250 °C. Based on the findings, the Yucca fiber may be suitable for various applications such as a reinforcement material in the composites applications and can be turned to yarn for textile applications.

Gradually modified fibers of Yucca Filifera (Asparagaceae) as biodegradable and mechanical reinforcement of polypropylene composites

“…The resultant slightly higher fiber's crystallinity in Table 4 was due to the partial removal of non‐crystalline materials such as external lignin and hemicellulose. As a comparison, recent studies reported the fiber crystallinity of agave Yucca ( Asparagus ) up to 66%, depending on the temperature of chemical extraction 32 . In another report, the crystallinity of Yucca ( Aloifolia ) leaves calculated by the Segal method was 69.43% 33 .…”

Extraction and Characterization of Bismarck Palm Fibres

“…The crystal size of the BPF was 5.22 nm. This smaller crystal size made the BPF more chemically reactive and water-soluble, which might improve the dyeing of these fibres (18) .…”

“…The C = C aromatic ring and C-H vibration of lignin were associated with the peak at 1640 cm -1 , whereas the C-H deformation of cellulose and lignin was associated with the peak at 1384 cm -1 . In addition, a peak at 1034 cm -1 shows the existence of the C-H rocking vibration in cellulose (18) .…”

Extraction and characterization of fiber from the flower stalk of Sansevieria cylindrica

“…Some fibers, potentially suitable for incorporation into composites, are obtained from the leaves of plants that belong to the former Agavaceae family. This is the case for Agave americana , where natural retting, possibly followed by chemical treatment, proved effective for the production of composites (Hulle et al 2015; Madhu et al 2020; Murugesan et al 2022), and for Yucca filamentosa , where ambitions to obtain possible textile products from short fiber winding were also exposed (Nair et al 2013; Moghaddam and Karimi 2022). As far as the Sansevieria genus is concerned, three types offered fibers that might be used for the production of composites, namely Sansevieria trifasciata (Adeniyi et al 2020), Sansevieria ehrenbergii (Sathishkumar et al 2013), and particularly Sansevieria cylindrica (Sreenivasan et al 2015), in which a larger number of studies on the fibers has been carried out.…”
