FIELD: polymer materials. SUBSTANCE: woven material is used as filler for building, preferably roofing, materials. To achieve desired deformation at alternating temperatures owing to manufacturing fabric with 6-8% increased elongation and increased tarring capacity, each synthetic thread from those interwoven in warp and chute is executed as composite consisting of glass and polymer threads. The latter are interlaced or intergrown with glass threads in a fancy manner: polymer thread serves as core and glass thread is driven on. Their ratio varies from 70:30 to 85:15, respectively. Chute threads in woven material can be textured. Ratio of warp and chute threads is 1: (1-4). Polymer utilized may be of polyester group or polypropylene or polyamide. EFFECT: improved consumer quality of between materials. 4 cl |
