Problems solved by technology

Existing paper-making felt base fabrics are repeatedly pressed under high-line pressure conditions, which easily causes the base fabrics to embed each other, thereby blocking the gaps, greatly affecting the water permeability of the paper-making felt, and shortening the service life of the paper-making felt
[0003] Moreover, the existing paper-making felts are all used to manufacture paper products with a smooth and delicate surface, and cannot produce wrapping paper and surface stickers with characteristic streaks on the surface, which cannot meet people's needs for such paper products

Embodiment 1

[0017] like figure 1 As shown, a characteristic streak blanket is composed of a base fabric bottom net 1, a fiber core layer 2, a fiber surface layer 3 and a fiber back layer 4, and the bottom of the base fabric bottom net 1 is a fiber back layer 4, and the base fabric bottom net 1 is the fiber core layer 2, and the top of the fiber core layer 2 is the fiber surface layer 3. The warp threads of the base fabric base net 1 are composed of thick warp threads and thin warp threads, and the thick warp threads and thin warp threads are arranged at intervals from each other. The diameter of the thin warp threads 0.55mm, the thick warp diameter is 2.8mm, the weft diameter of the base fabric base net 1 is 0.44mm, and the weaving density of the warp of alternate thickness is to contain warp or weft 60 in every 10cm length.

[0018] The warp and weft threads of the base fabric base net 1 are elastic wool-like yarns, and the base fabric base net 1 is composed of a satin weave.

Embodiment 2

[0021] like figure 2 As shown, a characteristic streak blanket is composed of a base fabric bottom net 1, a fiber core layer 2, a fiber surface layer 3 and a fiber back layer 4, and the bottom of the base fabric bottom net 1 is a fiber back layer 4, and the base fabric bottom net 1 above is the fiber core layer 2, and above the fiber core layer 2 is the fiber surface layer 3. The thickness of the warp threads or the weft threads of the base fabric base net 1 are alternately thick and thin, the diameter of the thick thread is 3 mm, and the diameter of the thin thread is 1 mm. Or the weaving density of the weft is 50 warp or weft per 10cm length.

[0022] The base fabric base net 1 is a multi-layer base fabric structure, which includes radial base fabrics 5 and weft base fabrics 6 arranged at intervals, the warps of the radial base fabrics 5 are wool-like yarns with alternate thicknesses, and the wefts are Soluble fibers; the weft threads of the weft base fabric 6 are wool-lik...

Abstract

The invention discloses a blanket with characteristic streaks. The blanket comprises a base-cloth bottom web (1), a fiber core layer (2), a fiber surface layer (3) and a fiber back layer (4), warps with different thicknesses of the base-cloth bottom web (1) are arranged at intervals, or wefts with different thicknesses of the base-cloth bottom web (1) are arranged at intervals, the diameter of each thick warp or each thick weft is 3-8 times of that of each thin warp or each thin weft, and the weaving density of the warps with the different thicknesses or the wefts with the different thicknesses is defined in such a manner that 48-60 warps or wefts are arranged in each section with the length of 10cm. The blanket has the advantages that the warps with the different thicknesses or the wefts with the different thicknesses are adopted, so that pressures and water flow resistances of paper areas corresponding to the warps or the wefts with different diameters are different, further, the regular characteristic streaks are naturally formed on processed finished paper, and requirements of people on packaging paper, surface stickers and the like are met; and the warps with the different thicknesses or the wefts with the different thicknesses are adopted, void spaces of the blanket are larger as compared with a blanket in the prior art, a water permeation performance is good, water storage capacity of the blanket is strengthened, and a dewatering effect of the blanket is good.

Description

technical field [0001] The invention relates to the technical field of textile products for papermaking, in particular to a characteristic streak blanket. Background technique [0002] Papermaking felt is a special textile used in the press section of a paper machine. It is mainly used for dehydration, supporting paper sheets, and modifying paper sheets. Among them, dehydration is the key function, and it has the characteristics of changing with the use of time. The existing base fabrics of paper-making felts are repeatedly pressed under high linear pressure conditions, which easily causes the base fabrics to embed each other, thereby blocking the gaps, greatly affecting the water permeability of the paper-making felts, and shortening the service life of the paper-making felts. [0003] Moreover, the existing papermaking felts are all used to manufacture paper products with a smooth and delicate surface, and cannot produce wrapping paper, surface stickers, etc. with characte...
