Plastic woven bag based fabric technology index is a hard index to solve the problem of woven bag products.
1. Density and density tolerance
Braid density is the number of warp and weft threads in a 1-inch braid. The woven bag national standard GB/T 8946 stipulates the woven density and density tolerance. Commonly used woven cloth density is 10*10, 12*12. 14*14.
2. Tensile strength
Tensile load is also called tensile strength, tensile strength. The braided fabric is subjected to tensile load in both meridional and zonal directions. Therefore, it is called meridional and zonal tensile load.
3. Mass per unit area
The unit area weight of the woven cloth is weighed by the plate multi - directional sampling, the electronic gram weight is weighed to calculate the unit gram weight of the product. The gram weight of square meter depends mainly on the warp and weft density and the thickness of the flat wire. The gram weight of square meter affects the tensile strength of braided cloth.
4. Width
Various braid widths directly affect the bag-making process and coating composite requirements. Due to the characteristics of plastic, the product has the retractability, the production process needs to be enlarged wide.
5. Handle
PP flat silk woven fabric feel thick, quite wide, rough and hard. HDPE flat silk braids feel soft, lubricated, not dense. Add calcium masterbatch in PP flat silk material, feel quite wide, PP less HDPE will make it softer. Flat wire narrow. Weave. Feel soft; Flat silk wide, weave cloth folding silk, feel rough.
