Internet language: rich and willful! In fact, not only are wealthy and self-willed, but people’s personalities are sometimes self-willed; is self-willedness good or bad? The editor can only say that each has its pros and cons. In fact, it is not only self-willed, but woven bags also have "toughness". The toughness of woven bags is a key factor that determines the service life of woven bags. Many customers will consider their storage period when purchasing woven bags, but they don’t know that the life span of woven bags is based on the toughness of the woven bags! Let me introduce you today:
The cooling and forming of the membrane: the strength of the flat wire is advanced, the problem of broken wire is solved, and the strength of the woven bag cloth is increased. The water tank is a component part of the wire drawing machine. The unevenness of the cooling water temperature in the water tank affects the physical function of the diaphragm after cooling and forming, and it is also an element that affects the strength of the flat wire. This is because polypropylene is a crystalline polymer material, and its crystal shape has many kinds. In the process of natural cooling, relatively large α-type spherulites are often formed. The stretching orientation of such spherulites is harder than that, which is not conducive to wire drawing.
The ratio of raw materials: The supplement masterbatch is one of the important components of the ratio of raw materials. The result is to improve the physical function of the flat yarn and reduce the capital. With the addition of the supplementing amount of the supplementing masterbatch, the tensile strength of the flat yarn will gradually decrease.
Woven bag manufacturers have strict marking requirements for the width design and feel of the woven bag during the production process. The width of various woven fabrics directly affects the bag making process. Give you a specific introduction:
For the tube cloth, the warp is used to indicate the width, and the warp 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. 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. In terms of the feel of plastic woven bags, there are differences in the classification of different materials.
PP flat wire braid has a thicker feel, wider and harder. HDPE flat wire braid feels soft, smooth, 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. Their toughness is also different, the toughness is not easy to break, so the service life is longer!
