Weaving density refers to the number of 100mm × 100mm knitted fabric, the number of latitude and longitude yarn. National standard GB / T8946-1998 provides that "the bag flat, in the bag on the next two diagonally delineated 100mm × 100mm two blocks, the square outside the bag and the edge of the line away from 100mm, visual box by the number of latitude , The average value, the count when the end of the last less than one, according to a meter. "National standards in the provisions of the weaving density at the same time, the provisions of the density tolerance. The weaving density depends primarily on the packaging product, which is determined by the user.
raw material
Plastic woven nouns: woven bags mainly speaking: plastic woven bags are polypropylene (English name pp) as the main raw material, the extrusion, stretching into flat yarn, and then by weaving, preparation, bag made of.
parameter
The commonly used woven fabric density is 36 x 36 root / 10 cm & lt; / RTI & gt; and 40 x 40 root / 10 cm & lt;
1. Weave density tolerance.
The weaving density tolerance refers to the number of strands that are more than the given standard weave density or reduce the number of flat yarns.
2. Weaving cloth unit area quality.
The weight per unit area of the woven fabric is expressed in terms of the weight of the square meter, which is an important technical index of the woven fabric. The weight of the square meter mainly depends on the weft density and the thickness of the flat yarn, the square meter weight affects the tensile strength of the woven fabric, the load capacity, the square meter weight is the production enterprise control cost is a main link.
3. Weave cloth tension load.
Tensile load is also called tensile strength, tensile strength. For the woven cloth to bear the warp and weft direction of the tensile load in two directions, so that the warp, weft stretch load.
4. Width.
A variety of woven fabric width directly affect the bag making process. For the tube cloth with the fold that the width, folding is equal to half the circumference of the circle.
Width of the width of all woven cloth weaving after the width of the volume, in the exhibition cutting, printing, sewing, made of the width of the bag should be slightly smaller than the width of the coiling, we call the width of retraction.
5. feel.
PP flat woven fabric feel more solid, very wide, rough some.
HDPE flat woven fabric feel soft, smooth, not dense.
In the PP flat wire material to add calcium masterbatch, feel very wide, PP less HDPE will make it more soft.
Flat wire narrow, weaving flat, soft to the touch, flat wire width, woven fabric folded when more than silk, feel rough.
