Abstract
Products made of conventional insect-repellent fibers, typically mosquito nets, have suffered from the following disadvantage: when the mosquito nets, folded up for their storage, are used, there are 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 is hard to crease when folded up, and an insect-repellent net made of the same. The invention relates to an insect-repellent fiber comprising a high density polyethylene, a linear low density polyethylene, an insect-repellent compound and porous particles, and showing an elongation percentage of 25 to 40%, measured according to JIS L 1013; and an insect-repellent net obtained by raschel-knitting the same insect-repellent fiber.
Description
Technical field
The repellent net that the present invention relates to insect-repellent fiber and make by this insect-repellent fiber.
Background of invention
Known insect control net (normally mosquito net) has been widely used as up to now and has been used for protecting individual and livestock not to be subjected to the device of the influence of sanitary insect pest (for example mosquito and fly class, particularly mosquito).JP-A-4-665509/1992 discloses the insect control net product by the yarn acquisition of netted braiding fiber crops, cotton or resin fibre, is generally mosquito net.To such an extent as to this mosquito net has the enough little sizing grid that prevents that mosquito etc. from therefrom passing through, make that being suppressed mosquito enters its mesh, prevent individual's contact mosquito thus.
Summary of the invention
Mosquito net folds in its transportation, it is sprawled and hangs to use.In case use,, and sprawl again and hang to use again with the folding preservation of mosquito net.The mosquito net of reusing by this way and keeping produces wrinkle thereon gradually, thereby causes disadvantageously, occurs making mosquito enter the slit of this mosquito net between the bottom of mosquito net and bed surface.
Because the inventor to addressing this problem the effort of having done of going deep into, finds to have contact between the wrinkle easiness (creasing ease) of the elongation of the insect-repellent fiber that constitutes mosquito net and this mosquito net, has therefore finished the present invention based on this discovery.
The invention provides insect-repellent fiber, it comprises high density polyethylene (HDPE), LLDPE, insect-repellent compound and porous particle, and it has 25～40% the elongation of measuring according to JIS L 1013 (elongation percentage).
The present invention further provides repellent net by La Xieer braiding (raschel-knitting) acquisition of this insect-repellent fiber.
Insect-repellent fiber of the present invention even when folding, also be difficult to produce fold.The repellent net that is obtained by the La Xieer of this insect-repellent fiber braiding also is even also is difficult to produce fold when folding.Therefore these materials are applicable to mosquito net.
The description of preferred implementation
Insect-repellent fiber of the present invention comprises high density polyethylene (HDPE), LLDPE, insect-repellent compound and porous particle.This insect-repellent fiber is for example by following preparation: high density polyethylene (HDPE), LLDPE, insect-repellent compound and porous particle are mediated in extruder, should be mediated mixture and extrude as strand, then with its stretching.Although can respectively this high density polyethylene (HDPE), LLDPE, insect-repellent compound and porous particle be put into extruder, but preferably at first prepare the masterbatch of this insect-repellent compound and use this masterbatch, because the good dispersion of this insect-repellent compound and this porous particle.Preferably; the masterbatch of this insect-repellent compound is by following preparation: at first with mixer etc. this insect-repellent compound is mixed with porous particle so that this insect-repellent compound is loaded on this porous particle, then this porous particle is mediated mutually with this LLDPE.Load on insect-repellent compound on this porous particle becomes and handles easily before.Therefore in addition, use the porous particle and the LLDPE of load insect-repellent compound thereon, the masterbatch of this insect-repellent compound can prepare under low relatively temperature, can be reduced in the loss of this insect-repellent compound in the preparation process of this masterbatch.
Said components is mediated in extruder, the mixture of mediating is extruded as strand.The strand of extruding is cooled to 15～40 ℃ temperature, in 95 ℃ or higher heating bath, it is stretched to its 7～9 double-length then.Can obtain to have the insect-repellent fiber that is determined as 25～40% elongation according to JIS L 1013 thus.The inventor has been found that between the elongation of this insect-repellent fiber and the wrinkle easiness by the repellent net of the plain weave gained of this insect-repellent fiber and has contact, and the insect-repellent fiber of finding to have 25～40% elongation is difficult to produce wrinkle.Have less than 25% or the insect-repellent fiber that surpasses 40% elongation when folding, have wrinkle on it, therefore be difficult to use.The mosquito net that forms of making of the repellent net of being made by this insect-repellent fiber forms between its bottom and bed surface easily and can make mosquito enter gap in this mosquito net.This mosquito net is useless.
The density that is used for the present invention's high density polyethylene (HDPE) is generally 0.935g/cm
3Or it is higher.The density that is used for the present invention's LLDPE is generally 0.850～0.934g/cm
3Or it is lower.This high density polyethylene (HDPE) can be Alathon or ethene and the copolymer with alpha-olefin of 3～20 carbon atoms.This LLDPE is ethene and the copolymer with alpha-olefin of 3～20 carbon atoms normally.The example of alpha-olefin comprises propylene, 1-butylene, 1-hexene and 4-methyl-1-pentene, especially preferred propylene and 1-butylene.
The example that is used for the insect-repellent compound of insect-repellent fiber of the present invention comprises pyrethroid compound, for example permethrin (permethrin), cyphenothrin (cyphenothrin), d-phenothrin (d-phenothrin), 4-resmethrin (4-resmethrin), sumicidin (fenvalerate), fenpropathrin (fenpropathrin), ether chrysanthemum ester (etofenprox) and tralomethrin (tralomethrin).Also can use the insect-repellent compound of non-pyrethroid compound according to the final use of insect-repellent fiber of the present invention.Be included in the surface that this insect-repellent compound in this insect-repellent fiber is exuded to this fiber.When insect (for example mosquito) touches this insect-repellent compound that is exuded to fiber surface, produce expelling parasite and insecticidal action.Therefore, vapour pressure is 1 * 10 in the time of 20 ℃
-6MmHg or lower low evaporation insect-repellent compound are preferably as insect-repellent compound of the present invention.Use has the insect-repellent compound of this vapour pressure, and this insect-repellent fiber can have good anthelmintic action in over a long time.
Silica or the analog porous particle that acts among the present invention.This porous particle is used in combination with this insect-repellent compound, so that this insect-repellent compound loads on this porous particle.Therefore, this insect-repellent compound can be stablized in over a long time and oozes out.The average grain diameter of used porous particle is generally 0.01～40 μ m, preferred 0.03～20 μ m.Porous particle with too little average grain diameter is difficult to be dispersed in this insect-repellent fiber.Porous particle easier plugged filter that makes extruder in the manufacture process of this insect-repellent fiber with too big average grain diameter, this makes the stable manufacturing of this insect-repellent fiber become difficult.
Preferably, insect-repellent fiber of the present invention comprises high density polyethylene (HDPE), LLDPE, insect-repellent compound and the porous particle that weight ratio is 80～93:5～15:1～3:1～3.Insect-repellent fiber of the present invention with this composition has good balance between toughness, rigidity and draftability.Therefore, the repellent net that is obtained by the La Xieer of this insect-repellent fiber braiding (raschel-knitting) is difficult to produce wrinkle when folding, so is applicable to mosquito net.
Insect-repellent fiber of the present invention can be included in the common additives of adding usually in the processing of high density polyethylene (HDPE) or LLDPE, for example antioxidant, pigment, lubricant etc.
