| Abstract | The objectives of this research were to 1) study the evenness of the sacred lotusspun yarn and 2) study the effects of cultivars and stem parts of the sacred lotus on thephysical properties of the lotus spun yarn. The materials used for this study were thestems of two cultivars of sacred lotus flower, namely Nelumbo nucifera ?Album Plenum?and N. nucifera ?Roseum Plenum?, at the age of 3 months. The yarn spinning methodapplied was jute spinning. The yarns were tested for physical properties according to themethod of American Society of Testing Materials Standards (ASTM). It was found that theevenness of the obtained spun yarns was classified as below grade D level. The obtainedyarn numbers were 522.65-828.10 tex. The yarns made from ?Roseum Plenum? fibers hadhigher yarn number than the yarns of ?Album Plenum?. The yarns from upper stem fibershad higher yarn number than the lower stem fibers yarn. The values of tenacity were1.700-3.020 g/tex. The yarns made from ?Album Plenum? fiber had higher tenacity thanthe yarns made from ?Roseum Plenum? fibers. Tenacity of lower stem fibers yarn washigher than the yarns made from upper stem fibers. The values of elongation were 1.390-2.098%. The ?Album Plenum? yarns had higher elongation than the yarns made from?Roseum Plenum? fibers. Lower stem fibers yarn had higher elongation than the yarnsmade from upper stem fibers. The cultivars of the lotus significantly affected yarn numberand tenacity. Parts of lotus stems significantly affected to yarn number, tenacity andelongation. Interaction between cultivars and stem parts of sacred lotus highly influencedto yarn number, tenacity and elongation. |
