The paper presents an investigation of the enhancement of hydrocarbon extraction from calotropis procera. An extraction yield of 8% has been obtained, with toluene as the solvent. An increase in the extraction yield to 11.5% has been achieved by modification of the design of the conventional 'Soxhlet' extractor. A further enhancement in extraction has been achieved by pretreatment of the biomass with alkali or acid. This pretreatment results in an extractive or hydrolytic breakdown of the plant structure and hence exposes the hydrocarbons to solvent attack. As alkali pretreatment of ground biomass resulted in a much higher extraction, it was studied in further detail with more alkalis of varying strength. An enhancement from 8 to 18% has been achieved by pretreatment with 1 N sodium hydroxide. Analytical studies by the use of IR and NMR have been conducted to prove that the enhancement in extraction is due to efficient extraction of hydrocarbons.

“…The latter, which can be manually separated from the seeds, is the fibre that will be discussed here. Owing to its soft lustre, good hand‐feel, biodegradability and natural antibacterial activity , the fibre from the seed of C. procera is now acknowledged to be a novel green fibre and is attracting increasing interest from researchers in the textile industry . One problem of making this kind of fibre into fabrics is that it is too smooth to spin into yarn in its pure form; however, this can be solved by prior physical or chemical treatment .…”

Studies of the fibre structure and dyeing properties of C alotropis gigantea , kapok and cotton fibres

Calotropis gigantea, kapok and cotton fibres are all natural cellulose fibres, but the first of these is rarely used in textile fabrics. In this study, the structure and chemical composition of these three kinds of fibre were studied, and the dyeing properties of fabrics made from each of them were compared. The purpose of this was to provide a theory basis for the application of C. gigantea fibre in the textile industry. The surface morphology and cross‐section of C. gigantea fibre in comparison with kapok and cotton were studied by scanning electron microscopy. Their fibrous structures were analysed by Fourier Transform‐infrared spectroscopy and X‐ray diffraction. The mechanical properties and water absorption capabilities were also measured and compared. Both C. gigantea fibre and kapok fibre exhibit a high degree of hollowness (80–90%), and no natural twist exists; there is a certain amount of lignin and hemicellulose in C. gigantea fibres; the crystallinity of C. gigantea fibres is 42.54%, and its crystallinity orientation index is 85.40%. C. gigantea fibre has the lowest tenacity but has the highest water content of the three kinds of fibre. The results of dyeing tests show that C. gigantea fabric has the lowest dye uptake and dye fixation.

“…Over the past decades, the study focus on Calotropics gigantea's medicinal value and its extract's energy value [1][2] has been the subjects of various previous researchers. It has been proved by some researchers that the akund adopted from Calotropics gigantea could substitute or supplement cotton as raw materials for textile fabric and might reduce the possible damage to the environment, as well as the feasibility of the application in composite material field [3][4] .…”

As a kind of environment-friendly fiber, akund will create considerable interest in the apparel industry due to its fine luster, good moisture absorption, renewable and pollution free feature. This research is a comparative study of the physical properties of akund/cotton material and pure cotton material. Results show that the enhanced structure of akund/cotton compact yarn typically results in a lower hairiness and improved mechanical properties. However, the weaving of this kind akund/cotton blended yarn may meet a lot difficulty since its tenacity value hardly meet the minimum value calls for weaving. Another important guidance is that it necessary to reduce short fiber content that may be present in the yarn structure to adopt best evenness.
