Examples of the knotless net which can be applied to the paper string reticulated structure of the present invention are shown in FIGS. 1 to 7. That is, FIG. 1 shows a lead-through type having a structure in which each yarn of two net yarns are mutually crossed and extend straight passing through the joint part of the net yarn, FIG. 2 shows a zigzag type having a structure in which each yarn of two net yarns are mutually crossed 2 to 3 times and the net yarn extends in a zigzag shape, FIG. 3 shows a hexagonal type having structure in which each yarn of two net yarns are mutually crossed 3 to 4 times and the net yarn extend straight via a joint part, FIG. 4 shows a Russell net having structure that is called “a lace net”, FIG. 5 is a gauze net (ordinary gauze net) having a structure in which woof crosses through a space of twisted warps to form a net, FIG. 6 is a gauze net (improved gauze net) having a structure in which the woofs mentioned above are twisted to reduce sliding of mesh, and FIG. 7 is a fabric net having a structure in which yarns are simply crossed in fabric net. These are the embodiments of the present invention.
In the case in which rectangular shape basket (cloth basket or vegetable basket) is produced with the reticulated structure, as shown in FIG. 9, a rectangular reticulated structure shown in FIGS. 1 to 7 is prepared as a body part 21, four edges are bent and raised to a certain height, to form bottom part 21 a and side part 21 b. If the flexibility of the mesh is not utilized, bending overlap parts 21 c are required at four corners of the side part. As shown in FIG. 10, the bending part is formed by the bending overlap part 21 c formed at the side part 21 b and the corner of 21 b.
An edge 21 d of the opening part is required for taking in and out, it is desirable that the edge be nicely formed by knitting or joining with paper string.
As the UV absorbent, cyanoacrylate based UV absorbent such as 2-ethylhexyl-2-cyano-3, 3′-diphenylacrylate, ethyl-2-cyano-3, 3′-diphenylacrylate, or octyl-2-cyano-3, 3′-diphenylacrylate, benzophenone based UV absorbent such as 2, 4-dihydroxybenzophenone, 2-hydroxy-4-methoxybenzophenone, or 2-hydroxy-4-octoxybenzophenone, benzotriazole based UV absorber such as 2-(2′-hydroxy-5′-methylphenyl)benzotriazole, or 2-(2′-hydroxy-5′-t-octylphenyl)benzotriazole, benzoate based UV absorbent such as resorcinolmonobenzoate, 2, 4-di-t-butylphenyl-3′, 5′-di-t-butyl-4′-hydroxybenzoate can be used.
As the hindered amine light stabilizer, bis (2, 2, 6, 6-tetramethyl-4-piperigil) sebacate, tetrakis (2, 2, 6, 6-tetramethyl-4-piperidil)-1, 2, 3, 4-butanetetracarboxylate, bis (1, 2, 2, 6, 6-pentamethyl-4-piperidil).di (tridecyl)-1, 2, 3, 4-butanetetracarboxylate, or condensate of 1-(2-hydroxyethyl)-2, 2, 6, 6-tetramethyl-4-piperidinol and diethyl succinate can be used.
Next, this base paper was slit into thin tape shapes having a width of 40 mm by bobbin winder, this tape was twisted 28 times/30 cm by a paper twisting machine to produce paper string having diameter of 3 mm. The strength of this paper string was 15 kg measured by Japanese Industrial Standard Z 1518.
Except that water slurry was prepared by mixing 80 weight % of NUKP and 20 weight % of Manila hemp pulp and beating into 60° SR, base paper was prepared under the same conditions as in Example 1.
Mixed pulp in which 60 weight % of foreign hard wood unbleached kraft pulp (LUKP) and 40 weight % of domestic soft wood unbleached kraft pulp (NUKP) were mixed is beaten into 55° SR to prepare a water slurry, and wet paper strength enhancing agent (trade name: polyfix301, produced by SHOWA HIGH POLYMER CO., LTD.) comprising polyamide epichlorohydrin resin was added into this water slurry, to account for 2% of the water slurry to prepare raw material for paper. The raw material was processed to a base paper having basic weight of 26.9 μm2 by a fourdrinier paper machine.
Next, this base paper was slit into thin tapes having a width of 40 mm by a bobbin winder, this tape is twisted 28 times/30 cm by a paper twisting machine to produce a paper string having a diameter of 3 mm. However, the paper was often torn, and it was difficult to form paper string. Furthermore, it was also difficult to form a vegetation net, agricultural net, biodegradable construction net, and types of article container.
