Some PP ribbon It is difficult to identify the front and the back of the book because of its special style. Now let's see how to distinguish the positive and negative sides of the PP ribbon factory!
As a matter of fact, we can recognize the pattern and the front of the pattern of the webbing by means of clear and clean patterns, clear lines, clear layers and bright colors. However, the specific resolution method is as follows:
1、 Generally, the patterns on the front of the webbing are clearer and more beautiful than those on the back.
2、 The front pattern of plant and color matching patterned fabrics with striped appearance must be clear and pleasing. This pattern is especially obvious when weaving jacquard belts.
3、 The convex and concave convex fabrics are compact and delicate on the front, with strip or pattern convex patterns, and rough on the back, with long floating lines.
4、 Wool fabric: single side woolen fabric, with the pile side being the front side of the fabric. For double-sided fleece fabric, the front side shall be the smooth and tidy side.
5、 Observe the selvage of pp fabric: if the selvage is smooth, the neat side is the front side of the fabric.
6、 For double-layer, multi-layer and multiple fabrics, if the warp and weft density of the front and the back is different, the front side has a larger density or the front side has better raw materials.
7、 Yarn fabric: The front side of the fabric is the prominent side with clear lines.
8、 Towel webbing: take the side with high terry density as the front.
