Problems solved by technology

In use, the gaps of the papermaking felt are easily blocked, resulting in a decrease in water permeability and a shortened service life; in addition, the papermaking felt is running at high speed on the paper machine, requiring its relative position to the paper machine to be kept accurate during initial installation and operation. Inaccurate, the blanket is easy to run off, gradually deformed, affecting the service life of the blanket

Embodiment Construction

[0016] The specific implementation manners of the present invention will be briefly described below in conjunction with the accompanying drawings.

[0017] As shown in the figure: a new type of papermaking felt, which is composed of a fiber surface layer 1, a fiber core layer 2, a base cloth layer 3 and a fiber back layer 4 from top to bottom, and is characterized in that: the base cloth layer 3 and the fiber surface layer 1. The fiber core layer 2 and the fiber back layer 4 are all interwoven by needle punching. The base fabric layer 3 is composed of an overall thickened and reinforced strong fabric layer formed by interweaving warp threads and weft threads. The base fabric layer The upper warp thread 5 of the layer 3 is a wool-like yarn, the lower warp thread 6 is a nylon strand, and the weft thread 7 of the base fabric layer 3 is a nylon filament monofilament; the front of the new papermaking blanket is provided with a standard thread ribbon 8. The standard line ribbon 8 ru...

Abstract

The invention provides a novel papermaking felt which is sequentially woven from a fiber surface layer, a fiber core layer, a base cloth layer and a fiber back layer from top to bottom in a needled mode. The base cloth layer is formed by a strong cloth layer which is integrally thickened and reinforced and woven from warps and wefts. Wraps on the upper layer of the base cloth layer are wool-like yarns, warps on the lower layer are polyamide piled yarns, and wefts are polyamide long filaments. A standard line colored tape is arranged on the front of the novel papermaking felt, penetrates two sides of the felt and intersects with the felt vertically with a 90-degree angle formed in between. An arrow indicting the running direction of a papermaking machine is arranged at each end of one side of the standard line colored tape. The novel papermaking felt is high in strength, high in dewatering capability and long in service life, and improves paper quality. In addition, the standard line colored tape is arranged on the papermaking felt to adjust the position of the papermaking felt on the papermaking machine and ensure that the felt runs normally on the papermaking machine, and the service life of the papermaking felt is prolonged.

Description

technical field [0001] The invention relates to a paper-making felt in a paper-connecting and dehydrating device of a paper machine, in particular to a novel paper-making felt with good air permeability and a standard color ribbon. Background technique [0002] Papermaking felt is a high-performance dehydrating material, which plays the role of dehydrating, carrying, conveying and decorating paper sheets in the papermaking process of paper machines. The paper-making felt is used as the carrier of pulp and wet-sheet paper, which is continuously pressed by the press roller, so that the moisture enters the inner space of the paper-making felt and is taken out by it for dehydration. During use, the gaps of the papermaking felt are easily blocked, resulting in a decrease in water permeability and a shortened service life; in addition, the papermaking felt is running at high speed on the paper machine, requiring its relative position to the paper machine to be kept accurate during...
