Q
How to distinguish between square hole net and Dutch net?
A

1. Square mesh is divided into plain weave and twill weave.

Plain weave

 Also called tabby weave, linen weaveor taffeta weave, is the most basic type of weaves. In plain weave, the warpand weft are aligned so they form a simple criss-cross pattern. Each weftthread crosses the warp threads by going over one, then under the next, and soon. The next weft thread goes under the warp threads that its neighbor wentover, and vice versa.

Twill net

Twilled weave” is a weave type in which the warp wires and shute wires pass over two and under two in both directions. This is different from a plain weave, which is when the wires are woven one over and one under. As a result, “twilled weave” is often more pliable than a comparable plain weave wire mesh specification. By and large, twilled weave is often used in filtration applications. The images below illustrate twilled weave, but because twilled weave is usually reserved for fine mesh, identifying a twilled weave usually requires a mesh counter.

2. Dutch net isdivided into plain weave and twill weave.

Plain Dutch Weave

Similar with plain weave, just the weft and warp wire havedifferent wire diameter and different mesh sizeAnd the warp has two crosses acrossthe weft.

Twill Dutch Weave

Similar with twill weave, just the weft and warp wire havedifferent wire diameter and different mesh size, And the warp has two crosses acrossthe weft.
