Abstract

The utility model relates to a composite double-layer mark-free felt for papermaking; wherein, an inner layer fiber (2) and a surface fiber layer (1) are implanted into the facade of an upper layer base cloth (3), and a reverse fiber layer (5) is implanted under a lower layer base cloth (4). The papermaking felt is characterized in that the warps of the upper layer base cloth (3) are wool-like yarns with certain elasticity, the warps of the lower layer base cloth (4) are incompressible Kapron compound yarns, and the wefts of both the upper and lower base cloth layers (3,4) are long Kapron monofilaments; the fabric structures of the upper layer base cloth (3) and the lower layer base cloth (4) are 1/3 broken twill woven structures; the fibers of the surface, inner and reverse fiber layers (1, 2 and 5) are Kapron cut staples of 6 D-20 D, 20 D-30 D, and 30 D-40 D respectively. The mark-free papermaking felt has the advantages of good dehydration performance, no felt impression on the paper forming surface, desirable smoothness of the paper forming surface, and high quality; therefore, the felt can be used as the papermaking felt on a papermaking machine for manufacturing continuous paper webs.

Description

Composite double layer without felt mark felt

Technical field

The utility model relates to the composite double layer felt of felt, particularly without felt mark that a kind of paper machine of making continuous webs of paper uses.

Background technology

Existing composite double layer felt base cloth levels warp all uses the polyamide fibre strand, its dehydration property, stability and self-cleaning are better, but because the polyamide fibre strand is nonelastic, has Incoercibility, this kind felt enters press section of a paper machine when being subjected to the linear pressure of higher speed of a motor vehicle pressure roller, and base cloth is indeformable, and the vestige of polyamide fibre strand warp is reflected on the page, form the paper felt mark, influence paper flatness and quality of finished paper.

Summary of the invention

In order to overcome existing composite double layer felt base cloth easily forms impression on page defective, the utility model provides a kind of composite double layer without felt mark felt, makes its dehydration good, is not becoming on the paper to leave the woollen blanket impression, become the paper smooth surface smooth, quality is good.

The technical scheme that its technical problem that solves the utility model adopts is a kind of composite double layer without felt mark felt, form by surface fiber layer, inner fiber layer, upper strata base cloth, lower floor's base cloth and reverse side fibrage, be implanted with inner fiber layer and surface fiber layer on the base cloth of upper strata, be implanted with the reverse side fibrage below lower floor's base cloth, it is characterized in that upper strata base cloth warp is a rubber-like simulate wool yarn, lower floor's base cloth warp is incompressible polyamide fibre strand, and the parallel of upper and lower base cloth layer is the nylon monofilament long filament; The fabric construction of upper and lower base cloth layer is 1/3 brokentwlllweave weaving structure; The fibrolaminar fiber of surface, internal layer and reverse side that is implanted on the base cloth is respectively 6D-20D, 20D-30D and 30D-40D polyamide fibre short fiber.

The beneficial effects of the utility model are that dehydration is good, become no woollen blanket impression on the paper, and the flatness of page is good, quality is high.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model partial cross section view.

Fig. 2 and Fig. 4 are respectively that the utility model upper strata base cloth, lower floor's base cloth parallel and warp concern distribution map.

Fig. 3 and Fig. 5 are respectively the minimum weaving structure unit weavy grain figure of upper strata base cloth, lower floor's base cloth.

In Fig. 1: 1. surface fibre layer, 2. inner fiber layer, 3. upper strata base cloth, 4. lower floor's base cloth, 5. reverse side fibrage.

Broken line in Fig. 2 is represented interweave position relation of upper strata base cloth parallel and warp, and bullet represents to spin wool yarn line warp.

Broken line among Fig. 4 is represented interweave position relation of each root lower floor base cloth parallel and warp.Every group little bullet is polyamide fibre strand warp among the figure.

Black square is that warp is descending parallel last among Fig. 3 Fig. 5, and white square is that warp is descending at last parallel.

The specific embodiment

In Fig. 1, a kind of composite double layer without felt mark felt, form by surface fiber layer (1), inner fiber layer (2), upper strata base cloth (3), lower floor's base cloth (4) and reverse side fibrage (5), be implanted with inner fiber (2) and surface fiber layer (1) on the upper strata base cloth (3), be implanted with reverse side fibrage (5) below lower floor's base cloth (4), it is characterized in that upper strata base cloth (3) warp is that rubber-like spins the wool yarn line, lower floor's base cloth (4) warp is incompressible polyamide fibre strand, and the parallel of upper and lower base cloth layer (3,4) is the nylon monofilament long filament; The fabric construction of base cloth layer (3,4) is 1/3 brokentwlllweave weaving structure up and down, and the fibrolaminar fiber of surface, internal layer and reverse side that is implanted on the base cloth is respectively 6D-20D, 20-30D and 30-40D polyamide fibre short fiber.
