FIELD: textiles, paper.
SUBSTANCE: invention relates to moulding fabric for the moulding part of the paper-making machine. Fabric has an upper layer of weft threads and a lower layer of weft threads, passing in a direction perpendicular to the direction of the movement of the fabric in the machine. Upper (moulding) layer and lower (side of wear and tear) layer are joined forming a multilayered fabric. Compacting threads, passing in a direction perpendicular to the direction of movement of fabric in the machine, set between adjacent weft threads on the side of wear and tear. Compacting threads reduce the volume of emptiness on the side of wear and tear of the fabric without a considerable disruption to the air permeability and increasing the thickness of the fabric. This arrangement of compacting threads also leads to the increase in transverse strength and seam strength and reduces transverse movement of weft threads on the side of wear and tear.
EFFECT: increase in the transverse strength and seam strength and reduces transverse movement of weft threads on the side of wear and tear.
