FIELD: textile; paper.
SUBSTANCE: invention relates to needle-punched fabric and method of its production, and can be used as a base for production of constructional, finishing and other similar materials. Needle-punched material contains nonwoven fabric made of synthetic fibres, reinforcing and binding filaments. Note, that reinforcing filaments are made of fibre glass and arranged along nonwoven fibre uniformly. Moreover, nonwoven fibre is made of two inner lengthway fibrous webs and two external cross fibrous webs clamped by needlepunching. Notably, that reinforcing filaments made of fibre glass are arranged uniformly between the layer of lengthway inner fibrous web and one cross fibrous web.
EFFECT: enhancement of nonwoven fabric uniformity, functional capabilities enhancement of needle-punched fabric and cost reduction.
