Pp Woven Cloth Is The Use Of Polypropylene As Raw Materials
- Jun 07, 2017 -


Pp woven cloth is based on polypropylene, acrylic fiber as raw material, by the two groups of parallel yarn (its shape is flat) composition, a group along the loom longitudinal (fabric direction) called warp yarn, another The horizontal arrangement of the group is called weft. With different preparation of weaving equipment and technology will be woven and weft woven together woven into cloth, PP Woven Cloth according to the use of different types of knitting into different thickness and density, the general weaving geotextile thin vertical and horizontal have a very strong tensile Strength (longitude than latitude), with good stability. , In the dry and wet state can maintain sufficient strength and elongation, woven cloth, PP Woven Cloth also known as spinning geotextile, woven geotextile.

Pp woven cloth is the general raw materials are modified, lubricants, color masterbatch and so on. According to the use of plastic woven products, the choice of raw materials are also different. In general, with high-density polyethylene woven fabric feel, soft, low temperature resistance are better. PP Woven Cloth The rich source of polypropylene, low prices, so the plastic products widely used as the main raw material of polypropylene.

Pp woven cloth is molded into extrusion. In order to ensure the quality of slabs, the melt flow rate (MFR) is generally chosen as the raw material. The melt flow rate of the polypropylene usually used for plasticizing is between 2 and 5 g / 10 min. Melt index is small, flat wire strength is high, PP Woven Cloth but the molding difficulties; the other hand, the flat wire strength is low, forming easier. If a large amount of filler is added to the formulation, it will reduce the flowability of the material during the molding process and add a small amount of plasticizer or lubricant to increase its fluidity.

Polypropylene renewable materials are also used in the production of plastic products, although its physical properties and quality than the new material is poor, PP Woven Cloth but as long as the rational selection, but also to achieve the required standards. If the flat yarn produced by the recycled material is not bright, a small amount of lubricant can be added to the raw material formulation to improve.

Pp woven cloth is under pressure in the three links should be filtered. The purpose of the filter there are three: First, the impurities in the filter material; Second, the stability of the flow of materials; Third, make the product dense. At present, most of the filters used are 60 mesh high-elastic steel mesh. In general, PP Woven Cloth the number of layers of the filter should be 15-30 layer is appropriate (depending on experience), too little flow instability, the product is not dense; too much resistance is too large and burst broken three links.

Pp woven cloth is cut, printing, sewing and other processes made after the woven bag, can be used for various types of various types of materials packaging.
