“…As demonstrated in our previous study, 23 the compressional S-S curve in a compress-release cycle could not follow the same path, and would generate the hysteresis loop. Since the lifting speed of the compressional feeler of the tester was faster than stress relaxation of the KFA, the true compression recovery of the sample could not be measured.…”

“…In this stage, fibers in the KFA were in good contact and compactness, and undertook the main resistance to compression, which made the change of strain slow down drastically. As reported in our previous study 23 on the KFA compressibility, the hollow kapok fiber could be crushed into a ribbon-like body or cell walls under a repeated compression load, especially for the wet-treated KFA.…”

“…22 However, the lumen structure of kapok fiber is difficult to preserve under multiple compression during the manufacturing and utilization process. 23 In other words, some of kapok's unique properties may decline quickly in the manufacturing process. It is important to understand the resilience of kapok under repeated compression and how its resilience can be affected by environmental factors.…”

Kapok fiber is light, buoyant, and excellent in thermal insulation because of its high degree of hollowness. However, it is difficult to preserve the lumen structure of kapok fiber under repetitive compression in the course of manufacturing and utilization, and then the fiber may lose its unique features quickly. Thus, it is critical to know the resilience of kapok under repeated compression and how it can be affected by environmental factors. In this paper, we studied the compressional resilience of fibrous assemblies made of slightly carded kapok fibers by using an Instron compression tester. The nonlinear compressional behavior of the assemblies was observed in the repeated transverse compressing cycles with a constant compressional strain, and three characteristic stages of the entire compressing cycles—linear elastic, metamorphosis, and densification—were identified. The plastic and the visco-elasto-plastic compressional deformations were characterized from the compressional stress–strain curve. It was found that the conditioning humidity and the number of compressing cycles could affect the compressional resilience of the kapok fibrous assembly, and that the dry-treated kapok fibrous assemblies possessed better resilience and higher strains than the wet-treated ones.

“…However, due to their hollow structure, kapok fiber aggregates have key properties, including superhydrophobicity and porosity, ideally suited for life-saving supplies due to their maneuverability and increased buoyancy, as well as other attributes that artificial buoyancy materials lack, such as biodegradability, acid/alkali resistibility and natural abundance [45]. For textile uses, kapok fibers are short and light so kapok fiber used for fabrics or yarns must be blended with other cellulosic fibers, such as cotton or rayon, in order to improve its stability [49]. However, blending kapok with cotton or other fibers to make fabrics or yarns could reduce the amount of water and resources used during manufacturing, reducing the overall carbon footprint and environmental impact of the end product, in contrast to a similar product produced entirely of cotton or synthetic fibers.…”

The species of the genus Ceiba produces fruits with fibers with a high content of cellulose. The fiber is used for textiles, cushion filling and for industrial purposes and its characteristics have been studied in some species including Ceiba pentandra (kapok), C. speciosa and C. aesculifolia. The use of the trunk and seeds of Ceiba has also been described for different species. This article presents a review on the biological diversity of the genus Ceiba (Malvaceae). The genus Ceiba has 18 recognized species that are distributed naturally in America and Africa. However, some Ceiba trees have been introduced to various countries, especially in Asia, due to their ornamental interest and potential uses for their fiber. Ecophysiological studies of different Ceiba species have shown that resistance to adverse environmental conditions varies from species to species. Therefore, Ceiba species are considered potentially useful in restoring ecosystems impacted by human activity. The information related to the classification, morphological characteristics, phenology, ecophysiology and distribution of the different species will be extremely relevant for the sustainable production of kapok fiber. Finally, the recent genomic and transcriptomic studies also provide a valuable resource for further genetic improvement and effective use of Ceiba trees.

“…Although challenges such as short length, brittleness, and low cohesive force limit its direct application in spinning, kapok fibers can be blended and spun with other fibers. 13 Meanwhile, kapok fiber as a filler wadding can be well applied to thermal insulation, sound absorption and buoyancy life-saving materials. 14,15 Due to the hydrophobic properties of waxes, many scholars have focused their research on kapok fibers for oil-water separation, dye adsorption and wastewater treatment.…”

The pollution caused by petroleum-based waste has motivated the development of ecologically friendly bio-based materials. Natural fibers are becoming increasingly popular as a renewable and biodegradable resource. In this study, we prepared a kapok/waste silk nonwoven (KSN) by wet-laid and hot-pressing, which had adequate mechanical strength, hydrophilic, lipophilic, and biodegradable properties. The effects of the kapok fiber proportion on the morphology, air permeability, softness, mechanical property, wettability, and biodegradability of KSN were studied. The results demonstrated that the thickness, porosity, air permeability, and softness decreased as the proportion of kapok fiber increased. The mechanical property was significantly enhanced, and the breaking strength increased from 0.58 MPa to 10.85 MPa. With the increase in the proportion of kapok fiber, the spreading time of oil and water increased and decreased respectively, and the static contact angles were below 50°. Degradation rate improved with the increase of kapok fiber proportion, with a maximum degradation rate of 49.41% (30 days). Therefore, the multifunctional, low-cost, easily prepared, and biodegradable kapok/waste silk nonwovens is a promising bio-based material with superior application prospects in dressings, facial mask substrate, packaging, and related fields.
