Plastic woven bags in the production of woven fabric, what are the important indicators is to determine the quality of woven bags, which is any woven bag manufacturers can not be ignored, as the so-called good raw materials coupled with good technology in order to produce good products.Qingdao Johnson for you to introduce the main process indicators for the production of plastic woven fabric base
①Weaving density and weaving density tolerance
Weaving density refers to the number of warp and weft yarns in 100mm×100mm woven fabric. The standard specifies the knitting density and density tolerance at the same time. Woven density mainly depends on the packaging products, decided by the user. Commonly used woven fabric density is 36 × 36 / 10cm, 40 × 40 / 10cm, 48 × 48 / 10cm.
②Woven Density Tolerance
Weaving density tolerance is more than the given standard density or reduce the number of roots of flat wire.
③Woven fabric tensile load.
Tensile load is also known as tensile strength, tensile strength. For the woven fabric to withstand the warp and weft direction of the tensile load in both directions, it is called the warp, weft tensile load
④Mass per unit area of woven fabric
The weight per unit area of woven fabric is expressed in grams per square, which is an important technical index of woven fabric. Square grams mainly depends on the density of the warp and weft and the thickness of the flat wire, square grams affect the tensile strength of the woven fabric, load capacity, square grams is a major part of the production company to control the cost.
⑤Width.
The width of various woven fabrics directly affects the bag-making process. For the cylinder fabric, the width is expressed by folding warp, which is equal to half of the circumference.
Width retraction, the width of all woven fabrics after weaving and rolling, in the roll cutting, printing, sewing, the width of the bag made of slightly less than the width of the roll, we call the width retraction.
Feeling.
PP flat silk fabrics feel thicker, broader, thicker and harder; HDPE flat silk fabrics feel softer, lubricated, not dense. Add calcium masterbatch in PP flat silk material, feel broad, PP less HDPE will make it softer.
Flat silk is narrow, flat weaving, soft touch, flat silk is wide, more folded silk when weaving cloth, rough touch.
