Abstract
In this paper the burning speed of cotton and staple fibre surface was investigated experimentally by the method of rotation drum, varying the burning angle and water content.
Following results were obtained :
1. As sample burned upwards, the influence of angle on surface burning speed was small at angles from 0 to 30 degrees, but became very great at about 60 degrees.
As downwards, the surface burning speed was scarcely affected by the angle of sample.
2. The surface burning speed was decreased conversely in accordance with the increase of water content, and this effect was greater at larger angles of sample.
