Mokher Y. Research and perfection of the methods of technological analysis of flax and hemp straw

The object of research: flax and hemp straw, retted- straw and fibre. The aim of research: improvement of methods of technology analysis of flax and hemp straw. The instrumental estimation fibre was made by well-know methods. The algorithms of definition of errors of count flax and hemp fibre were worked out for the first time. The program security for processing of results of technological analysis by computer was created for the first time. The empirical formula for calculation of count of torn flax was concluded. It was proved that the method of preparation of flax (heat-water retting, spreading) do not influence considerably on results of technological analysis. The improved methods of technological analysis of flax and hemp were offered and implemented. The methodics may be used in the scientific - receach establishments, often on the enterprises of processing of bast fibre raw material.
