Accompanying drawing explanation
Fig. 1 is that the present invention for illustrating circumferentially having of fibre section a plurality of (8) protuberance spins the sectional view of shape of cross section of the flat leafy cross section polyester fiber possessed.
Detailed description of the invention
Next, spinning of the present invention is described in detail.
Spinning of the present invention is the spinning flat leafy cross section polyester fiber of 20 ~ 80 quality % and the cellulose fibre of 20 ~ 80 quality % being carried out mixed cotton.
Cellulose fibre used in the present invention is selected from the cellulose fibre of at least a kind in the semisynthetic fibres such as regenerated fiber or acetic acid esters such as the natural fabrics such as fiber crops, cotton (cotton) and silk (silk), viscose rayon (viscoserayon), copper ammonia fibre (cupra) and solvent method spinning fibre element (solvent-spuncellulose).Wherein, consider from operability, versatility and functional viewpoint, preferably use the regenerated fibers such as viscose rayon, solvent method spinning fibre element.
Cellulose fibre used in the present invention preferably arbitrary, shape of cross section is the cellulose fibre at the circumferentially irregular flat pattern of tool.By circumferentially having concavo-convex, water imbibition is uprising, and by capillarity, uniform liquid is spread, and therefore, has following effect: have rapid-drying properties, easily keeps dry feeling and refrigerant sense.
Above-mentioned protuberance number is circumferentially preferably 6 ~ 14, is more preferably 8 ~ 12.When the number of the protuberance circumferentially existed of shape of cross section is less than 6, space tails off, and water imbibition, liquid retainability and diffusivity are not enough, and in addition, the diffuse reflectance of light reduces, and barrier property also reduces.And then, because contact point during contact skin reduces, so feel becomes coarse.In addition, when the number of protuberance is greater than 14, compared with polyester fiber, the rigidity step-down of cellulose fibre, easily weares and teares, and yarn intensity reduces.And then water imbibition becomes too high, the liquid of impregnation remains in fiber, cannot evaporating liquid rapidly, and rapid-drying properties becomes not enough.In addition, from the viewpoint of skin contact, the shape of protuberance preferably makes circular shape.
In addition, the filament denier of cellulose fibre is preferably 1.0 ~ 5.0dtex.Filament denier is 1.2 ~ 2.2dtex more preferably.If filament denier is less than 1.0dtex, then sometimes exist easily be wrapped in carding machine (card) cylinder (cylinder) on trend, operation is significantly reduced by property.There is the trend easily producing spinning defect in result.In addition, if filament denier is greater than 5.0dtex, then feel when contacting the skin of people is hardening, presents trend undesirable in use in soft feel.In addition, interfibrous space is caused to become excessive, so there is the significantly reduced trend of water imbibition because filament denier becomes conference.From the viewpoint of polyester fiber with mixed cotton etc. other form the intertexture of fiber high, carding machine operation can be improved by property, the fibre length of cellulose fibre is preferably 30 ~ 64mm.Fibre length is more preferably 35 ~ 51mm.As the commercially available product of cellulose fibre, the artificial silk (trade name " CORONA ") etc. of DAIWABORAYON Inc. can be enumerated.
In spinning of the present invention, the containing ratio of described cellulose fibre is 20 ~ 80 quality %.If the composite rate of cellulose fibre (containing ratio) is less than 20 quality %, then because the water imbibition containing immersion fluid dies down, so diffusivity reduces, in spinning of the present invention, dry feeling, refrigerant sense reduce.And, in spinning of the present invention, because the distinctive soft feel of cellulose fibre also suffers damage, so skin sense of touch when using is deteriorated.In addition, if the composite rate of cellulose fibre is greater than 80 quality %, then water imbibition become too strong, and the liquid of impregnation remains in fiber, and liquid cannot be made to evaporate rapidly.Also namely, rapid-drying properties is lacked.
The polyester forming the polyester fiber used in the present invention refers to by terephthalic acid (TPA) and ethylene glycol, 1, the condensation reaction of ammediol (trimethyleneglycol) or butanediol etc. and the high molecular polymer generated, and the condensation product of decanedioic acid, adipic acid, trimellitic acid, M-phthalic acid and P-hydroxybenzoic acid etc. and ethylene glycol etc., and comprise the polyester polymers etc. of other polyesters.
The flat leafy cross section polyester fiber used in the present invention is its shape of cross section is have 6 with the polyester fiber of the flat pattern of upper convex portion.When the number being present in the protuberance circumferentially of shape of cross section is less than 6, the space formed between adjacent fiber tails off, and water imbibition, liquid retainability and diffusivity are not enough.And the diffuse reflectance of light reduces, and barrier property also reduces.When the number of protuberance is greater than 12, from the feature of the manufacture method of polyester fiber, there is the trend extremely reduced in degree of profile, the space formed between adjacent fiber tails off, as described above, and liquid retainability and diffusivity deficiency.By making shape of cross section be flat pattern, can form space between fiber, water imbibition, liquid retainability and diffusivity become good.And the diffuse reflectance of light increases, and barrier property becomes good.And then, because the filamentary hair down of each root is good, so soft feel can be obtained.
Fig. 1 represents an example of the filament shape of cross section of the flat leafy cross section polyester fiber used in the present invention.In FIG, the shape of cross section of the flat leafy cross section polyester fiber possessed in the spinning of the present invention of circumferentially having of fibre section a plurality of (8) protuberance is illustrated.
In FIG, A is the maximum length of the cross section of above-mentioned flat leafy cross section polyester fiber.B is the Breadth Maximum of the cross section of flat leafy cross section polyester fiber, refers to the length of line segment that intersect vertically with described maximum length A, that be connected the Breadth Maximum between protuberance summit.In addition, C refers to that maximum jog place connects the length of the line segment between adjacent projection summit.Further, D refers to that maximum jog place hangs down into the length of the vertical line of point at the bottom of recess from the line connected between adjacent projection summit.E refers to maximum length A for symmetry axis, the extreme length between two relative protuberance summits in line segment except Breadth Maximum B.
In the present invention, use its shape of cross section to be have 6 with the polyester fiber of the flat pattern of upper convex portion, the number of protuberance is preferably 7 ~ 13, is more preferably 8 ~ 12.In addition, from the viewpoint of skin contact, the shape of protuberance preferably makes circular shape.
For the flat leafy cross section polyester fiber used in the present invention, importantly, the flat leafy cross sectional shape of its filament cross section meets flatness that following formula (1) defines and the degree of profile that following formula (2) defines.And then, meet protuberance that following formula (3) defines than being preferred version.
Flatness (A/B)=2.0 ~ 3.0 (1)
Degree of profile (C/D)=1.0 ~ 5.0 (2)
Protuberance ratio (E/B)=0.6 ~ 0.9 (3)
In spinning of the present invention, flatness (A/B) is 2.0 ~ 3.0.When flatness (A/B) is less than 2.0, the hair down of fiber is poor, cannot obtain soft feel.On the other hand, if flatness (A/B) is greater than 3.0, then stiffening sense is little, easy atrophy.And throwing, degree of profile worsen.Flatness (A/B) is more preferably 2.0 ~ 2.7, and more preferably 2.0 ~ 2.5.
In addition, degree of profile (C/D) represent described flat multi-leaf-shaped in be positioned at the size of the recess between protuberance and protuberance, if this value is large, then represent that recess is little, if this value is little, then represent that recess is large.If degree of profile (C/D) becomes large, then because recess shoals, the space formed between fiber also diminishes, so there is the trend of water imbibition and diffusivity reduction.And, the trend that the diffuse reflectance that there is light also reduces, barrier property also reduces.Therefore, degree of profile (C/D) is less than 5.0.
On the other hand, when degree of profile (C/D) is too small, the easy bending of recess of fibre section, cannot flat pattern be kept, and, because friction can cause fiber easily impaired, so likely damage skin when rubbing with skin.From the viewpoint of these, degree of profile (C/D) is more than 1.0.Consider from above-mentioned viewpoint, degree of profile (C/D) is 1.0 ~ 5.0.And then consider from water imbibition and diffusible viewpoint, degree of profile (C/D) is more preferably 1.0 ~ 4.0.And then consider from the retentivity of flat pattern, water imbibition and diffusible balanced viewpoint, 2.0 ~ 4.0 is preferred scheme.
In addition, protuberance ratio (E/B) represent described flat multi-leaf-shaped in, with maximum length A for symmetry axis, the length ratio of length E between Breadth Maximum B and maximum protuberance summit in addition, it has following implication, is the index of the deformation extent measuring generally elliptical shape (obtaining during its line on each protuberance summit of description connection Breadth Maximum B and E, maximum length A).Protuberance is than time too small, and along with recess depths reduces, its shape of cross section becomes and is substantially equal to flat criss-cross shape.Therefore, capillarity effect reduces, and water imbibition and diffusivity reduce.In addition, during with skin contact, owing to being similar to flat cross shape, so the protuberance number of contact reduces, skin sense of touch and flexibility reduce.Therefore, protuberance is than being preferably more than 0.6.On the other hand, at protuberance than excessive, during due to fiber each other concavo-convex chimeric, the part that recess blocks completely becomes many, therefore space is reduced, and water imbibition and diffusivity reduce.In addition, during with skin contact, because its shape is for being similar to flat hexagonal shape, therefore the protuberance number of contact reduces, and skin soft-touch reduces.From the viewpoint of these, protuberance ratio (E/B) is preferably less than 0.9.Consider from above-mentioned viewpoint, protuberance ratio (E/B) is preferably 0.6 ~ 0.9.And then consider from its balanced viewpoint, protuberance ratio (E/B) is preferably 0.6 ~ 0.8, is more preferably 0.7 ~ 0.8.
The containing ratio of flat leafy cross section polyester fiber in spinning used in the present invention is 20 ~ 80 quality %.If the composite rate (containing ratio) of flat leafy cross section polyester fiber is less than 20 quality %, then because the hydrophobicity of spinning reduces, so become the trend being difficult to evaporate the moisture absorbed, rapid-drying properties is not enough, and skin sense of touch is also deteriorated.In addition, if the composite rate (containing ratio) of flat leafy cross section polyester fiber is greater than 80 % by weight, then due to capillarity effect die down, the diffusivity of liquid reduces, therefore damages with dry feeling during skin contact, refrigerant impression.From the above considerations, as preferred harmony, the flat leafy cross section containing ratio of polyester fiber in spinning is 30 ~ 70 quality %, is more preferably 40 ~ 60 quality %.
The filament denier of the flat leafy cross section polyester fiber used in the present invention is preferably below 2.0dtex.Filament denier is more preferably 1.0 ~ 2.0dtex, more preferably 1.2 ~ 1.8dtex.If filament denier is higher than 2dtex, then due to the distinctive rigidity grow of polyester fiber, so there is the stimulation situation that also grow, soft feel are also impaired of skin sense of touch.And because the space formed between fiber becomes excessive, so capillarity effect dies down, the diffusivity of liquid reduces, and there is the trend of damaging with dry feeling during skin contact, refrigerant impression thus.In addition, if filament denier is lower than 1.0dtex, then the trend that operation is deteriorated by property, productivity ratio reduces in carding machine operation is had.
In the flat leafy cross section polyester fiber used in the present invention, in order to improve barrier property and flexibility, inorganic particulate can be contained.
The containing ratio of inorganic particulate is preferably 0.2 ~ 2.5 quality %, is more preferably 0.2 ~ 2.2 quality %, more preferably 0.3 ~ 2.0 quality %.When the containing ratio of inorganic particulate is less than 0.2 quality %, there is the trend impaired with the friction increase of cellulose fibre, soft feel.And the trend that the diffuse reflection that there is light becomes insufficient, permeation-proof performance reduces.In addition, when the containing ratio of inorganic particulate is greater than 2.5 quality %, there is the trend that spinning process is reduced by property, generation guide member (guide) is worn and torn, and there is the trend of degree of profile reduction when spinning flat leafy cross section polyester fiber.And then, because extinction effect plays a role consumingly, so there is the trend of whiteness difference, forfeiture colour generation.
In addition, from the viewpoint of the operation in spinning by property, the fibre length of flat leafy cross section polyester fiber is preferably 30 ~ 64mm, more preferably 35 ~ 51mm.
Next, spinning of the present invention and its manufacture method are described.
The twist factor of spinning of the present invention is preferably the scope of 3.0 ~ 4.5.When twist factor is less than 3.0, there is the trend of sufficient yarn intensity of can not get, there is broken yarn when causing spinning, trend that intensity when making braided fabric reduces.In addition, if twist factor is greater than 4.5, then there is the trend being caused producing hardhead yarn by backtwisting, in addition, also having the trend of coarse hard sense when making braided fabric.
Spinning of the present invention can use flat leafy cross section polyester fiber and cellulose fibre to be manufactured by common spinning method, and ring spinning frame (comprise and terminate vortex-like fashion), air spinning frame etc. can be used to manufacture.
In addition, blending method also can be flat leafy cross section polyester fiber and this blending of 2 kinds of cellulose fibre, within the scope of blending ratio of the present invention, carry out blending with other fibers.For the number of spinning, particularly when for internal material, shirt material, 30 ~ 53 is preferred scheme, and 40 is preferred scheme.
The braided fabric formed by spinning of the present invention also can be 100% braided fabric employing the present invention's spinning, but the present invention's spinning at least containing 40 quality % is preferred scheme.When the ratio of spinning of the present invention is less than 40 quality %, there is the trend being difficult to obtain the water imbibition effect produced by the combination of flat leafy cross section polyester fiber of the present invention and cellulose fibre.In addition, in braided fabric of the present invention, spinning of the present invention can also be used in the scope being less than 60 quality %, except spinning of the present invention, also interweave with handing over and compile other spinning, long filaments etc.
Spinning of the present invention and comprise this spinning braided fabric owing to having the feel of water imbibition, rapid-drying properties and barrier property and softness concurrently, so inner shirt, pants, sweater, white garments, sweater and national costume etc. can be suitable as.
