Definitions
- the present invention relates to insect-repellent fibers and insect-repellent net made of the insect- repellent fibers.
- insect pest-controlling nets typically mosquito nets
- hitherto have been widely used as means for protecting persons and cattle from sanitary insect pests such as mosquitoes and flies, particularly mosquitoes.
- the insect pest-controlling net products typically mosquito nets, are obtained by net-like weaving the yarns of hemp, cotton or resin fibers described in JP- A-4-665509/1992.
- Such a mosquito net has mesh sizes so small enough as to prevent mosquitoes, etc. from passing therethrough, so that the mosquitoes are inhibited from entering the meshes thereof to thereby protect persons from contacting the mosquitoes. Disclosure of the Invention
- Mosquito nets are folded up during the transport thereof, and are spread and hang for use. Once used, the mosquito nets are folded up and kept, and are again spread and hang for use.
- the mosquito nets repeatedly used and kept in this way gradually have creases thereon, so that, disadvantageously, there occur clearances between the bottoms of the mosquito nets and floors to permit mosquitoes to enter the mosquito nets.
- the present invention provides an insect-repellent fiber which comprises a high density polyethylene, a linear low density polyethylene, an insect-repellent compound and porous particles and which has an elongation percentage of 25 to 40%, measured in accordance with JIS L 1013.
- the present invention further provides an insect- repellent net obtained by raschel-knitting the same insect- repellent fiber.
- the insect-repellent fiber of the present invention is hard to crease even when folded up.
- the insect-repellent net of the present invention, obtained by raschel-knitting the same insect-repellent fiber, is also hard to crease even when folded up. These materials are therefore suitably used for mosquito nets. Best Modes for Carrying out the Invention
- the insect-repellent fiber of the present invention comprises a high density polyethylene, a linear low density polyethylene, an insect-repellent compound and porous particles.
- the insect-repellent fiber is made as follows, for example: that is, the high density polyethylene, the linear low density polyethylene, the insect-repellent compound and the porous particles are kneaded in an extruder, and the kneaded mixture is extruded as strands, which are then drawn.
- the high density polyethylene, the linear low density polyethylene, the insect-repellent compound and the porous particles may be charged in the extruder, respectively, it is preferable to previously prepare a master batch of the insect-repellent compound and to use this master batch, since the dispersibility of the insect-repellent compound and the porous particles is good.
- the master batch of the insect-repellent compound is prepared by previously mixing the insect- repellent compound with the porous particles with a mixer or the like to support the insect-repellent compound on the porous particles, and then kneading such porous particles with the linear low density polyethylene.
- the insect- repellent compound previously carried on the porous particles becomes easy to handle.
- the master batch of the insect-repellent compound, using the porous particles supporting the insect-repellent compound thereon and the linear low density polyethylene can be prepared at a relatively low temperature, and thus, the loss of the insect-repellent compound in the course of the preparation of the master batch can be reduced.
- the above components are kneaded in an extruder, and the kneaded mixture is extruded as strands.
- the extruded strands are cooled to a temperature of 15 to 40°C and are then drawn to be 7 to 9 times longer in a hot bath of 95°C or higher.
- an insect-repellent fiber having an elongation percentage of 25 to 40%, measured according to JIS L 1013, can be obtained.
- the present inventors have found that there is a correlation between the elongation percentage of an insect-repellent fiber and the creasing ease of an insect-repellent net obtained by plain-weaving the insect-repellent fiber, and found that an insect- repellent fiber having an elongation percentage of 25 to 40% is hard to crease. 7Vn insect-repellent fiber having an elongation percentage of less than 25% or exceeding 40% has creases thereon when folded up, and thus is hard to use. A mosquito net obtained by sewing an insect-repellent net made of such an insect-repellent fiber tends to cause a clearance between its bottom and a floor to permit mosquitoes to enter the net. Such a mosquito net is useless.
- the density of the high density polyethylene to be used in the present invention is usually 0.935 g/cm 3 or more.
- the density of the linear low density polyethylene to be used in the present invention is usually from 0.850 to 0.934 g/cm 3 or less.
- the high density polyethylene may be an ethylene homopolymer or a copolymer of ethylene with ⁇ -olefin having 3 to 20 carbon atoms.
- the linear low density polyethylene is usually a copolymer of ethylene with ⁇ -olefin having 3 to 20 carbon atoms. Examples of ⁇ - olefin include propylene, 1-butene, 1-hexene and 4-methyl- 1-pentene, among which propylene and 1-butene are preferred.
- insect-repellent compound in the insect-repellent fiber of the present invention examples include pyrethroid compounds such as permethrin, cyphenothrin, d- phenothrin, 4-resmethrin, fenvalerate, fenpropathrin, etofenprox, and tralomethrin.
- An insect-repellent compound other than the pyrethroid compounds may be used in accordance with an end use of the insect-repellent fiber of the present invention.
- the insect-repellent compound contained in the insect-repellent fiber bleeds to the surface of the fiber.
- insect-repellent compound When insect pests such as mosquitoes contact the insect-repellent compound bled to the surface of the fiber, an insect-repellent and insecticidal effect is produced. Accordingly, a low transpiration insect- repellent compound which shows a vapor pressure of 1 X 10 " ⁇ itimHg or lower at 2O 0 C is preferable as the insect-repellent compound of the present invention.
- the insect- repellent compound showing such a vapor pressure the insect-repellent fiber can exhibit an excellent insect- repellent effect over a long period of time.
- Silica or the like is used as the porous particles to be used in the present invention.
- the porous particles are used in combination with the insect-repellent compound so that the insect-repellent compound is supported on the porous particles.
- the average particle size of the porous particles used is usually from 0.01 to 40 ⁇ m, preferably from 0.03 to 20 ⁇ m.
- Porous particles having too small an average particle size are hard to be uniformly dispersed in the insect-repellent fiber.
- Porous particles having too large an average particle size are more likely to clog the filter of an extruder in the course of the manufacturing of the insect- repellent fiber, which makes it hard to stably manufacture the insect-repellent fiber.
- the insect-repellent fiber of the present invention contains the high density polyethylene, the linear low density polyethylene, the insect-repellent compound and the porous particles in the weight ratio 80 to 93 : 5 to 15 : 1 to 3 : 1 to 3.
- the insect-repellent fiber of the present invention having such a composition, is excellent in balance among tenacity, rigidity and elongation. Accordingly, an insect-repellent net obtained by raschel-knitting such an insect-repellent fiber is hard to crease when folded up, and thus is suitably used for a mosquito net.
- the insect-repellent fiber of the present invention may contain common additives such as an antioxidant, pigment, lubricant, etc. which are conventionally added in the processing of high density polyethylenes or linear low density polyethylenes. Examples
- Tester a constant rate of extension type tension tester
- Elongation percentate calculated from an elongation of a fiber when the fiber was cut
- This test piece was folded in four, and a load of 200 g was applied to the folded test piece (7.5 cm X 7.5 cm) for one hour. The load was removed after one hour had passed, and the folded test piece was spread. A resin sheet weighing 200 g (30 cm X 45 cm) was placed on the spread test piece and left to stand for 30 minutes. After that, the resin sheet was removed, and the creases of the test piece were observed.
- Example 1 (1) Preparation of Master Batch
- Porous particles (porous silica with an average particle size of 12 ⁇ m) (35.9 wt . parts) and permethrin (showing a vapor pressure of 5 X 10 7 mitiHg at 20°C) (38.6 wt . parts) as a pyrethroid type insect-repellent compound were mixed with a mixer.
- Zinc stearate (21.9 wt . parts) and a blue pigment (ultramarine violet) (3.6 wt . parts) were further added and mixed to obtain an insect-repellent compound-containing mixture.
- LLDPE linear low density polyethylene
- the above insect-repellent resin composition was melt- spun.
- a strand of this resin composition extruded with an extruder at a cylinder temperature of 130 to 210°C and a die temperature of 230°C, was taken off at a first take-off speed of 13 m/min. while being cooled with water, and was then introduced into a drawing water tank and was taken off in the drawing water tank in a boiling state (95°C or higher) at a second take-off speed of 105 m/min.
- an insect-repellent fiber drawn longer at a draw ratio of 8 was obtained.
- the fineness of this fiber was 190 denier.
- Comparative Example 1 An insect-repellent fiber was obtained in the same manner as in Example 1, except that the second take-off speed was changed to 85 m/min., and the draw ratio, to 6.5.
- the fineness of this fiber was 198 denier.
- the evaluation results of the obtained insect-repellent fiber are shown in Table 1.
- An insect-repellent fiber was obtained in the same manner as in Example 1, except that the second take-off speed was changed to 124 m/min., and the draw ratio, to 9.5. The fineness of this fiber was 194 denier.
- the evaluation results of the obtained insect-repellent fiber are shown in Table 1. Table 1
- An insect-repellent fiber comprising a high density polyethylene, a linear low density polyethylene, an insect- repellent compound and porous particles, wherein the elongation percentage of the fiber measured according to
- JIS L 1013 is from 25 to 40%.
