Polyester synthetic forming fabric is a commonly used filter mesh in the forming section of paper machine, the forming wire can be divided into 1 layer, 1.5 layer, double layer, 2.5 layer, and triple layer forming fabric, in order to increase the work life of the polyester forming fabric, Huatao weaves the nylon monofilament with better abrasion resistance in the weft, which makes the fabrics life longer and reduces the cost.
The 1.5 layer forming fabric is actually a 5-shed single layer forming fabric that have modified to have extra yarns which provides it the same properties as that of a double layer one. 1.5 layer forming fabric is easy to clean, increase sheet release as well as retention and with the extra fabric provides an excellent drainage.
The ideal 1.5 layer forming fabric for most paperboard and packaging grades applications, especially where a smooth top surface and long life potential are desired. In addition, Clean mesh yarn technology provides maximum resistance to premature fabric contamination.
Polyester 2.5 layer forming fabric are also known as support shute double layer forming fabric or double layer extra designs. It's a standard double layer design with an extra shute yarn added on the forming side between the 2 regular cross direction yarns. This yarn increase the pulp fibre support and meanwhile create a more open structure as the amount of wear side yarns is reduced, compared with the forming side.
2.5 layer forming fabric's weaving effect greatly increases the fiber support index due to the addition of a fine weave at the top. The ratio of the top and bottom wefts is 2:1. It suitable for paperboard,newsprint,writing paper,tissue paper,printing paper,kraft paper.
The SSB 3 layer forming fabric or "wire" of a paper machine is the continuous belt or belts of mesh screen upon which the paper sheet is formed. Most modern SSB 3 layer forming fabric are comprised of polyester monofilament. The weave pattern and layering of a SSB 3 layer forming fabric is designed to meet stringent requirements of dimensional stability, resistance to abrasion (on the wire side), minimum resistance to drainage, minimum wire-mark, and (sometimes) maximization of retention of fiber fines.
This type Chips that is designed to resist burning and melting at low temperatures.
Low Melting Point Polyester Chip for Hot Melt Yarn Masterbatch
Extrusion Grade Polymer for Hot-melt Adhesive Glue Coating
Description:
Generally speaking, the low melting point polyester chip refers to one specialty polymer with a melting point between 90 and 220.
The melting point of polyester is the temperature at which a solid crystalline substance changes from a solid state to a liquid. So it reflects the purity of polyester. Generally speaking, pure polyester is a partially crystalline polymer with a melting point of 265. But during actual production, some impurities exist in the polyester due to various side reactions. At the same time, the defects of polymer crystals and the difference in crystallinity will also affect the melting point. The common type of low melt polymer is 110. But we can also offer a melting point of 90, 120, 160, and 180.
Application:
Low-melt polyester chips can produce low-melting point fiber, low-melting point synthetic fiber, and thermal-melting mucilage. Its primary usage is acting as bonding fiber in nonwoven fabrics. The end usage lies in clothing, articles for bed, shoe uppers, sleeping bags, sofas, and hygiene products.
LM PET Chip is also the main raw material of masterbatch carriers. That is, low-melt PET chips, conventional chips, and dyes are mixed to produce the polyester color masterbatch according to a certain proportion. The production of this product is the introduction of polyester macromolecules into the modified copolymer unit. And its melting point is in the range of 100-120. Commonly used modifiers are phthalic acid, adipic acid, and trimethylolpropane.
Recently, LM Polymer is also extruded into the back coating of nonwoven, automotive interiors, foam, injection molding, PET sheets, and hot-melt adhesive/glue.
Low Melt Yarn is also called hot melt yarn or fusible yarn. There are sheath-core low-melt bicomponent yarn and full low-melt polyester yarn.

PET chip is TPA-based polyethylene terephthlic copolymer designed for various applications, especially for the bottle like drinking water & food container. It is a high molecular weight polymer with an 0.80 intrinsic viscosity.
Applications:
Used for packing bottles for drinking water such as pure water, natural mineral water and distilled water etc. The products are good processing performance. Mineral water, edible oil, hot fill bottle grade, food bottle grade Bottle-grade polyester chips are suitable for making the packing bottles for pure water, natural mineral water, distilled water, drinking water, flavoring and candy containers, PET sheet material etc
