Woven bags are common products in daily life and work. Like flour bags in our lives, they are a kind of woven bags. Like the bags of many companies, the woven bags of express companies often use woven bags. about woven bags, There are different densities and different weights. Today Xiaoou will talk to you about the density of woven bags, hoping to help everyone.
1. Weave density tolerance
Weave density tolerance refers to more than a given standard weave density or reduce the number of flat yarns.
2. The mass per unit area of woven cloth
The weight per unit area of woven cloth is expressed in grams per square meter, which is an important technical indicator for woven cloth. The tensile strength of the cloth, the load capacity, and the weight per square meter are a major part of the cost control of the production enterprise.
3. Tensile load of woven cloth
Tensile load is also called tensile strength and tensile strength. For a woven fabric to withstand the tensile load in both the warp and weft directions, it is called the warp and weft tensile load.
4. Width
The width of various woven fabrics directly affects the bag-making process. For the tube cloth, the width is indicated by the folded warp, which is equal to half of the circumference. Width retraction rate, the width of all woven cloth after weaving and winding, after unwinding, printing, and sewing, the width of the bag made should be slightly smaller than the width of the reel. We call the width retraction.
5. Feel
PP flat silk braid feels thicker, wider and thicker.
HDPE flat silk braid is soft to the touch, smooth and not dense.
Adding the calcium masterbatch to the PP flat wire material makes the hand feel very broad. Adding less HDPE to the PP will make it softer. The flat yarn is narrow, the weave is flat, the feel is soft, and the flat yarn is wide. When weaving the cloth, there are many folded filaments and the feel is rough.
