This value is comparable to the commercialized synthetic sorbent. Kapok seed oil protection could improve the utility of fiber, which reflected in increas-ing of in vitro NDF, DM and OM digestibility of native grass were supplemented by 10 and 15% KSO. Kapok is also called as silk cotton or java cotton. Kapok fiber is getting more and more extensive attention in research and application because of its excellent natural characteristics such as its lightness, super warmth, anti-bacterial, anti-mite etc. In general, this research was done to assist the oil spill cleanup technology and provide the best solutions for oil spill sorption for new biodegradable sorbent, raw kapok. The CMA possesses a great adsorption capacity of 78–348 times its weight. Unlike cotton fiber, kapok fiber is a fruit fiber adhered on the internal wall of seedpod. Kapok fiber possesses the features of thin cell wall, large lumen, low density, and hydrophobic–oleophilic properties. Kapok fiber … Kapok fiber is a silky cotton-like substance that surrounds the seeds in the pods of the ceiba tree. The kapok fiber is a single-cell natural cellulose fiber, with 64% cellulose, 13% lignin, 8.6% water, 1.4–3.5% ash, 4.7–9.7% water-soluble substances, 2.3–2.5% xylan and 0.8% waxes , . 52 J.Indon.Trop.Anim.Agric. This chapter focuses on the structure and properties of kapok fiber. In the present work, kapok fiber oriented polyaniline (KF-O-PAN) was prepared via a facile polymerization of aniline on the surface of KF and optimized using response surface methodology based on a central composite design. (a) Low-magnification SEM image of kapok fiber with diameter of 15-30 μm. Preparation of Flame Retardant Treatment for Kapok Fiber Weigh the quantity of kapok and PCL according to the experimental scheme. The influence of the kapok fiber on filtration performance of air filter papers against the di-(2-ethyl hexyl) sebacate (DEHS) oil aerosols was analyzed. Kapok or capok is a natural, cellulosic fiber. As shown in Fig. Table 3.1.1: Absorbancy of Kapok fiber When oil thickness exceeds 60 mm, a constant flux of 3.8–5.0 L/(m 2 min) can be achieved by the kapok wall of 55-, 75- and 95-mm thick respectively under the natural pressure gradient. Kapok seeds could easy separate from the fibers by a simple, sieve-like devices. Figure S2. 32 [1] March 2007 spplementation levels. Numerous pores in its cell wall form the pathways for gas molecules. There was a marginal drop in the crystallinity index of hemp fiber while sisal, jute, and kapok fibers showed a slight increase in crystallinity at caustic soda concentration of 0.8–30%.
