Based on the given data, it can be assumed that the main cause of the strength of non-
woven materials on the basis of natural silk wastes compared with materials based on chemical 
fibers is due to the good adhesion of the binder precisely to the silk fiber. 
Conclusion. 
As noted in the work / 8-9 /, the use of natural silk or waste of natural silk 
allows to obtain materials with good thermal insulating properties. Consequently, the partial 
replacement of chemical fibers on natural silk waste is justified and allows to improve the 
physico-mechanical properties of non-woven materials obtained by the thermopressive method. 
This should be especially noticeable to manifest in nonwoven materials from viscose fibers. For 
example, a replacement of 30% viscose on natural silk waste will increase their strength.
