Microstructural analysis and mechanical tests were conducted. Korean Journal of Chemical Engineering 2015, 32, 2534-2541. Flax fibers have been used for textile utilization such as woven, knitting and technical textiles for many centuries. Effect of chemical treatments using sodium chlorite, sodium hydroxide and acrylamide monomer on thermal behavior of coconut husk (coir) fibre has been studied by means of scanning electron microscopy (SEM) and thermogravimetric analyses (TG, DTG, DTA). In this paper, early research on the structure and properties of coir fibres has been critically reviewed. The mechanical properties like tensile strength, flexural strength, impact strength and the micro hardness showed an increment with respect to fibre loading as well as the alkali Chemical Treatment of coir fibre Chemical treatments are intended to improve at least one property of the composites. The coir is a natural fibre getting extracted from the husk of coconut. The tensile properties of the composite samples were measured for each fibre content value (5, 10 and 15%) with the help of the stress/strain curves. properties of the cement determined from various tests are shown in Table 1. A significant variation in fibre surface occurred by chemical treatments is clearly observed in SEM images. The coir is the fibrous material found between the hard, internal shell and the outer cover of a coconut. The Air Filled Porosity (AFP) defines the air spaces in the pot needed for good water dispersal and drainage. This is great for use as a growing medium. Laboratory experiments were conducted to study the physical, chemical and microbiological properties of coir. The laboratory result reveals that both fibres are effective in increasing the Marshall stability of the ordinary HMA. Natural fiber, palm, coir, chemical properties, physical properties. On the other hand coir fibre has 43.4% cellulose, 0.50% hemi-cellulose and 45.9% lignin. Coir fibre are coarser for textile applications and possesses highly variable properties. Due to the presence of high quantity of lignin, coir fibre is very hard. Flax Fiber: A rt of producing Linen from flax plant was known earlier than 2500 BC, though flax production was introduced to the industry in 12 th century.

The addition of coconut fiber to coconut dust increased the airspace (Air at - 10cm tension) but reduced easily available water. DOI: 10.1007/s11814-015-0069-z. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene.. This suggests that natural fibre composites have a potential to replace glass in many applications that do not require very high load bearing capabilities. The Perfect for use as a growing medium. Each of two kinds of bottom ash (coarse bottom ash, CBA, with particle size ≥5 mm; and fine bottom ash, FBA, with particle size ≥5 mm) were mixed with coir dust in the ratios 10:0, 9:1, 8:2, 7:3, 6:4, 5:5, and 0:10 (coir dust:bottom ash, v/v). The chemical composition of coir is given in table 1. The chemical composition of coir and other plant fibres is given in Table 3, which shows that brown coir fibres contain relatively low amounts of cellulose (35 per cent) but have high lignin content (32 per cent) 20. Levels of air space, however, varied considerably. Air Filled Porosity (AFP): 10 – 11%. Jute Fiber has some standard physical properties. During chemical treatment, hydrophilic -OH groups in the raw coir cellulose were converted to hydrophobic -O–Na groups. Picture 1 - Example of different coco fractions. Both raw and treated coir at 10, 15, 20, 25, 30, and 35 wt % were utilized during composite manufacturing. Hailiang Liu, Changfa Xiao, Qinglin Huang, Xiaoyu Hu, Wei Shu. 1.
