Development of the manual solitary reeling Japanese machine for reeling the mulberry silkworm bombyx Mori L. cocoons [electronic resource].

Includes references.

The aim of this study is to develop the manual solitary reeling machine which can be used in research studies and can be operated mechanically for reeling cocoons of Bombyx Mori L.. Some parameters were evaluated such as reeling speed. reeling time as indicator for silk yield and reeling efficiency. The obtained results of the developed reeling machine were as follow: A) Raw silk percentage 41%, floss percentage 3.6%, pelade percentage inside waste silk 9.4%, filament length 8.55 m. and filament weight 0.25 gm. B) The reeling speed increases from 60 to 160 rpm. the reeling time decreased from 12 to 4 min. this reeling speed tend to increase the productivity from 3.75 to 18.00 gm/h for reeling one cocoon. C) By increasing the reeling speed. from 140 to 160 rpm, the power consumption increased fromO.220 to 0.340 kW. While. pelade inside waste silk was decreased from 0.066 to 0.064 gm. The reeling time was decreased from 6 to 4 min. Also, productivity tend to increase from 11.85 to 18.00 gm/h.. for reeling cocoon by cocoon.
