AI Technical Summary

Technical Problem

In existing technologies, adding splicing yarns may reduce the surface properties and air permeability of paper machine fabrics.

Method used

By employing a specific weaving method, a prescribed woven pattern is formed through the combination of weft and warp yarns, ensuring that the bonding strength simultaneously suppresses the reduction in surface properties and breathability.

Benefits of technology

This approach effectively suppresses the reduction in the surface properties and air permeability of paper machine fabrics while ensuring bonding strength, thereby improving the fabric's durability and abrasion resistance.

Abstract

In the fabric according to the present disclosure, the upper-side warp yarns, which are arranged up and down with the lower-side warp yarns, have the same weaving pattern as the upper-side warp yarns when the binding weft yarns are removed. The binding warp yarns constitute at least one of the two warp yarns arranged up and down to form a group. The binding warp yarns and the warp yarns arranged up and down with the binding warp yarns are complemented with each other to form a woven pattern corresponding to a woven pattern formed by one upper warp yarn and a woven pattern corresponding to a woven pattern formed by one lower warp yarn. The upper-side warp yarns and the binding warp yarns are woven into the upper-side weft yarns to form an upper-side fabric formed in a predetermined weaving pattern for each warp row. The lower side warp yarns and the binding warp yarns are woven into the lower side weft yarns to form a lower side fabric formed in a predetermined weaving pattern for each warp row. The binding weft yarns form yarn knots passing through the upper side of two or less continuous upper side warp yarns, and are not adjacent in the warp direction.
