[0002] Dry blankets usually refer to products used in the drying section of multi-cylinder paper and board machines in the papermaking industry. They can play the role of paper sheet transfer, blanket cylinder transmission and paper sheet support to improve heat transfer efficiency and paper flatness. Flocking dry blankets are divided into polyester woven flocking dry blankets and polyester spiral flocking dry blankets in terms of structure; they are divided into endless and ended flocking dry blankets in terms of type; they are divided into single-sided and double-sided flocking dry blankets in terms of laying state. End-seam flocking dry blankets represent high-end products of flocking dry nets due to their high seam processing technology content and easy installation. Spiral flocking dry nets use polycool spiral dry nets or polycool woven dry nets with endless or seam types as the base net, and a certain fineness and amount of high-temperature resistant short fibers are implanted on the front or back of the net. It is a composite high-performance product that combines the advantages of needle-punched dry blankets and polycool dry nets. Through the spiral net, excess water can be squeezed out, which helps to form paper.

[0003] In the prior art, most spiral mesh flocking dry blankets have a smooth surface and a small contact area with the paper.
