Description

Composite needling papermaking felt

Technical Field

The utility model belongs to the technical field of papermaking felts, and particularly relates to a composite needling papermaking felt.

Background

By papermaking felt is meant a fabric felt used in the papermaking industry for the formation and transport of paper. The wet, upper and dry blankets may be classified according to locations on the paper machine, and the wet, upper and dry blankets may be classified according to locations on the paper machine. However, the existing papermaking felt has the following disadvantages: present papermaking felt is mostly woven by warp and weft and is formed, need carry out accuse water treatment to it when carrying the paper, has increased the transit time to the paper to reduced production efficiency, current papermaking felt uses long-time back in addition, its warp and weft break off easily, thereby influence the shaping effect of paper.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems in the prior art, the utility model provides the composite needling papermaking felt, the antistatic layers are arranged on the upper side and the lower side of the felt base layer, so that the condition that warp polyester fiber yarns and weft polyester fiber yarns generate static electricity is avoided, the safety is improved, the waterproof layers are arranged on the periphery, the upper side and the lower side of the antistatic layers and are made of felt coiled material waterproof layers, the water control time of the papermaking felt is reduced, the production efficiency is improved, the condition that the antistatic layers and the waterproof layers are broken due to friction can be avoided, the forming effect of paper is ensured, and the service life is prolonged.

In order to achieve the purpose, the utility model provides the following technical scheme:

a composite needling papermaking felt comprises a felt base layer, an antistatic layer and a waterproof layer; the blanket base layer is woven by double-filament warp polyester fiber yarns and double-filament weft polyester fiber yarns, the diameters of the warp polyester fiber yarns and the weft polyester fiber yarns are both 0.28mm, the weaving density of the blanket base layer is 40%, the upper side and the lower side of the blanket base layer are both provided with antistatic layers, the antistatic layers are CVC flame-retardant fabrics, the periphery, the upper side and the lower side of each antistatic layer are respectively coated with waterproof layers, the waterproof layers are felt coiled material waterproof layers, the blanket base layer is woven by the double-filament warp polyester fiber yarns and the double-filament weft polyester fiber yarns, the blanket base layer has high strength and good elastic recovery capability, is not deformed after being dried, is low in production cost, is formed by arranging the antistatic layers on the upper side and the lower side of the blanket base layer, avoids the condition that the warp polyester fiber yarns and the weft polyester fiber yarns generate static electricity, improves safety, and is formed by arranging the waterproof layers on the periphery, the upper side and the lower side of the antistatic layers, and the waterproof layer is a felt coiled material waterproof layer, so that the water control time of the papermaking felt is reduced, the production efficiency is improved, the condition that the anti-static layer and the waterproof layer are cracked due to friction can be avoided, the forming effect of paper is ensured, and the service life is prolonged.

Compared with the prior art, the utility model has the beneficial effects that: the woollen blanket basic unit is woven by the warp polyester fiber silk of mariages and the weft polyester fiber silk of mariages and is formed, higher intensity and good elastic recovery ability have, do not warp after the drying, low in production cost, set up the antistatic backing through the upper and lower both sides at woollen blanket basic unit, the condition that warp polyester fiber silk and weft polyester fiber silk produced static has been avoided, the safety is improved, set up the waterproof layer through all around and upper and lower both sides at the antistatic backing, and the waterproof layer is the linoleum coiled material waterproof layer, not only the papermaking woollen blanket accuse water time has been reduced, the production efficiency is improved, and can avoid antistatic backing and the cracked condition of waterproof layer because of the friction to take place, the shaping effect to the paper has been guaranteed, service life is prolonged.
