Abstract
The utility model relates to a novel paper making felt without felt mark, comprising an upper layer of fiber web, an upper layer of elastic membranous material, a layer of weaving ground web, a lower layer of elastic membranous material (as needed, or not) and a lower layer of fiber web The layers of elastic membranous material are clamped between the layers of fiber web and the layers of ground web. In the paper making felt without felt mark of the utility mode, the layers of elastic membranous material is sandwiched between the layers of fiber web and the layers of ground web; hereby, during the manufacturing procedure of needling felt, the influence of that the surface irregularity of the felt which is caused by the surface irregularity of the ground web is can be improved, and the phenomenon of that the broken ends of ground web thread are taken to the surface of the felt by a felting needle under the effect of the needling. The repairing work amount can be lightened. The novel paper making felt without felt mark has simple structure and convenient processing. The utility model is used to the pressing of paper making machine without felt mark. Compared with the similar products, the phenomenon of wet returning can be reduced by the novel paper making felt without felt mark.
Description
Affiliated technical field
The utility model relates to a kind of novel without felt mark felt, in particular for the paper machine pressed zone.
Background technology
At present, the felt on the known paper machine is the spacer screen needled paper-making felt, and its effect is the transmission l Water Paper, and sloughs moisture in the l Water Paper by squeezing, yet often because the woollen blanket surface exists pin trace or surface irregularity, easily stays felt mark at wet paper surface; When serious, make letterweight spend or crush, influence paper surface flatness and smoothness.Therefore, development of new without felt mark felt is necessary.
Summary of the invention
In order to overcome existing felt easily stays felt mark at wet paper surface in paper machine expressing process deficiency, for exploitation felt new product provides condition, the utility model provides a kind of press felt that is used for the paper machine, and this woollen blanket can thoroughly be eliminated felt mark.
The technical scheme that its technical problem that solves the utility model adopts is: felt structure comprises top fiber stratum reticulare, upper strata elastic membrane material layer, woven spacer screen layer, lower floor's elastic membrane material layer and lower floor's fiber web layer, and the elastic membrane material layer is clipped between fiber web layer and the spacer screen layer.
The beneficial effects of the utility model are: owing between web layer and spacer screen layer, sandwiched the elastic membrane material layer, so woollen blanket can improve the influence that causes the woollen blanket surface irregularity because of the spacer screen surface irregularity on the one hand in the acupuncture manufacturing procedure; Can eliminate or alleviate on the other hand because of needling action causes spacer screen silk broken end and be taken to the woollen blanket surface, alleviate patcher's workload by pricker.Felt structure is simple, easy to process, is used for the squeezing of paper machine, does not stay felt mark, compared with similar products, alleviates back wet phenomenon.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a without felt mark felt warp cross section structural representation of the present utility model.
Fig. 2 is a without felt mark felt broadwise cross section structure schematic diagram of the present utility model.
Fig. 3 is to be the fabric organization chart of example through the flat net of two-fold once on three in the without felt mark felt of the present utility model.
Among Fig. 1 and Fig. 2: 1. top fiber net, 2. lower floor's elastic membrane material, 3. weft yarn, 4. warp thread, 5. lower floor's fiber web, 6. upper strata elastic membrane material.
The specific embodiment
Once be a kind of spacer screen (seeing Fig. 3 organization chart) of present more employing through the flat net of two-fold on three, polyamide fibre 6 healds that adopt high-tenacity are as the material through weft yarn, and the heald diameter is 0.20-0.30mm.Wherein warp thread adopts 4 strands of healds, and weft yarn adopts monofilament.Press Fig. 3 organization chart processing spacer screen.After spacer screen being spliced into the ring network of specification requirement, carry out pre-HEAT SETTING.
After being installed in ring network on the needing machine, spread upper strata elastic membrane material 6 above it.Book films such as polyamide fibre, terylene are adopted in the membrane material suggestion, and thickness is that 0.15-0.50mm, hardness are Shore 40-70 °.
After spreading a certain amount of top fiber net 1 above the elastic membrane material 6, enter acupuncture.It is polyamide fibre 6 staple fibres of 5-10diner that length 76-98mm, fineness are adopted in 1 suggestion of top fiber net.
After finishing above-mentioned operation, woollen blanket is stood up.Back at spacer screen upper berth levels elastic membrane material 2 (on demand, can not adding) and a certain amount of lower floor fiber web 5 (it is polyamide fibre 6 staple fibres of 15-20diner that length 76-98mm, fineness are adopted in suggestion), and enter acupuncture, following machine after satisfying needling process.Repair subsequently, HEAT SETTING, back arrangement, promptly finish woollen blanket processing.
Claims (2)
1. without felt mark felt, it is characterized in that: it comprises top fiber stratum reticulare, upper strata elastic membrane material layer, woven spacer screen layer, lower floor's elastic membrane material layer and lower floor's fiber web layer.
2. without felt mark felt according to claim 1 is characterized in that: the elastic membrane material clip is between web layer and spacer screen layer.
