Pingdingshan bags

Commonly used density woven 根 36 × 36 / 10cm, 40 × 40 根 / 10cm, 48 × 48 根 / 10cm. 1, weave density tolerance: weaving density is the ratio of a given tolerance standard weave density or reduce the number of multiple flat yarn. 2, the quality of woven fabric per unit area: woven square meter basis weight is expressed as the number of grams of weight, it is woven an important technical indicators. Weight per square meter depending on the number of warp and weft density and thickness of the flat wire, square meter weight in grams of the impact tensile strength woven cloth, load capacity, weight per square meter company control number is a major part of the cost. 3, woven tensile load: tensile load, also known as tensile strength, tensile strength, tensile load for weaving Booker bear both the warp and weft directions, so that the warp and weft tensile load. 4, width: Width of various woven bag directly affect the process, the barrel off after indicating width cloth, folded by the equivalent of half the circumference. Width retraction, all woven weaving width after coiling, in unrolled cutting, printing, stitching, made of the width of the bag to be slightly smaller than the width of coiling, we call width retraction. 5. PP Flat Yarn knitted feel more solid feel, very wide, stiff some; HDPE flat yarn woven fabric feel soft, smooth, not tight; calcium compound added in PP Flat Yarn masterbatch, feel quite wide, PP in HDPE will make it less add some soft Biansi narrow woven flat, soft, flat wide, when woven silk folds more, feel rough. Types of foreign production mainly polyethylene (PE), polypropylene domestic production of major (PP), is a thermoplastic resin polymerized ethylene obtained. In the industry, but also copolymers of ethylene with minor amounts of α- olefins. Polyethylene odorless, non-toxic, feel like wax, has excellent low temperature properties (lowest service temperature up to -70 ~ -100 ℃), good chemical stability, resistance to most acid-base corrosion (intolerance with oxidation properties The acid), room temperature, soluble in common solvents, water absorption, excellent electrical insulation properties; but polyethylene for environmental stress (chemical and mechanical action) is very sensitive, heat aging poor. Polyethylene nature because of different varieties, depending on the molecular structure and density. Using different production methods can be of various density (0.91 ~ 0.96g / cm3) of the product. Generally available polyethylene thermoplastic molding method (see plastics processing) processing. Wide range of uses, mainly used to manufacture film, containers, pipes, monofilament, wire and cable, and other daily necessities, and as television, radar and other high-frequency insulating material. With the development of petrochemical industry, polyethylene production and rapid development, production accounts for about 1 / 4.1983 world total production capacity of polyethylene plastic total of 24.65Mt, the construction unit capacity of 3.16Mt.
