In the production of woven fabrics of plastic woven bags, what are the important indicators that determine the quality of woven bags? This is a factor that no woven bag manufacturer can ignore. It is just the so-called good raw materials and good craftsmanship that can produce good products. The editor of Bag Brother introduces the main process indicators of plastic circular woven fabric base production

①Weaving density and weaving density tolerance
　　Knitting density refers to the number of warp and weft yarns in a 100mm×100mm braid. While the weaving density is specified in the standard, the density tolerance is also specified. The weaving density mainly depends on the packaged product and is determined by the user. The density of commonly used woven cloth is 36×36 pieces/10cm, 40×40 pieces/10cm, 48×48 pieces/10cm.
②Weaving density tolerance
　　The weaving density tolerance refers to the number of flat yarns more than the given standard weaving density or reduced.
③ Tensile load of woven fabric.
　　 Tensile load is also called tensile strength, tensile strength. For woven fabrics to bear tensile load in both warp and weft directions, it is called warp and weft tensile load
④The mass per unit area of ​​woven fabric
The weight per unit area of ​​woven fabric is expressed in square gram weight, which is an important technical indicator of woven fabric. The square gram weight mainly depends on the warp and weft density and the thickness of the flat wire. The square gram weight affects the stretch of the woven fabric. Tensile strength, load capacity, and weight per square gram are a major link in cost control for production companies.
⑤ Width.
The width of various woven fabrics directly affects the bag making process. For the tube cloth, the width of the fold is used to indicate the width, and the fold is equal to half of the circumference.
Width shrinkage rate, the width of all woven fabrics after weaving and winding, after unwinding, cutting, printing, and sewing, the width of the bag made is slightly smaller than the width when winding, we call the width shrinkage
⑥ Hand feeling.
　　PP flat wire braid feels thicker, wider, and harder; HDPE flat wire braid feels softer, smoother, and not dense. Adding calcium masterbatch to PP flat yarn will give a wide hand feel. Adding less HDPE to PP will make it softer.
　　The flat wire is narrow, the weave is flat, the hand feel is soft, and the flat wire is wide. When weaving the cloth, there are many folds and the hand feels rough.
