strength also had positive significant correlations with bast (0.534*) and core (0.606*) fibres, thus the tensile strength can be determined during the plant growth using plant height. Emodulus positively correlated with plant height, base diameter, fibres yields and tensile strength. Based on this, the tensile strength and e-modulus corroborate as versatile selection tools. Accessions SAU75-414, GS14-52 and AEHC-3 combined high fibre yield with high bast fibre and yarn quality. In view of the properties, they are recommended for further experimentation for improvement on fibre yield and quality for use of the farmers and industrialists.
technique to produce spun kenaf-yarn (single or double-ply). The machine component includes two 0.5 kW electric motors positioned on
a 640×433×10 mm mild steel frame (with speeds of the electric motors
controlled by 0.5 kW variable frequency drives), twisting spindle, inlet
frustum, feed roller shaft, reeling and spinning shafts, bearings, and a
bevel gear. The machine was evaluated using different spinning speeds
(90, 100 and 110 rpm), reeling speeds (60, 70 and 80 rpm) and a kenaf
sample (Ifeken DI 400). At the spinning and reeling speeds combination
of 90 and 80 rev·min-1
, the developed machine was able to produce a
continuous length of kenaf yarn twisted at 95.5 turns per minute with a
production speed of 0.94 m·min-1
at the highest efficiency (88.9%) of
the machine. The level of twist of the spun yarn spun provides information on the required twist level for kenaf fibre as deviation from this
value was discovered to cause deformation on the spun yarn. This machine was able to reduce the drudgery involved in the production of
spun kenaf-yarn and the technology is expected to positively influence
kenaf’s growth and utilization in Nigeria.
