HOLLOW INDUSTRIAL FABRIC FOR SUPPORT LAYER OF SAFETY SLEEVE Russian patent published in 2009 - IPC D03D1/00 

FIELD: textile industry.

SUBSTANCE: fabric is made in the form of a closed hollow tube and formed with two-layer weave of core and filling threads, and the layers are connected in the edges. As the base weave, there used is the weave the core and filling rapport of which contains one long and one short overlapping with the average overlapping length equal to 1.5…2.0, weave coefficient is 4.5…16.0, and coefficient of connection is 4.1…6.8. In complete weave rapport, all short core and filling overlappings are located inside the sleeve, and long ones - outside the sleeve; at that, fabric stretching as to the core threads at 10% load of the breaking one is not more than 5%.

EFFECT: designing hollow industrial fabric for the support layer of safety sleeve, which has low stretching degree at maximum operating loads.
