Description

Sandwich construction knitted fabric
Technical field
The present invention relates to sandwich construction knitted fabric.In more detail, the present invention relates to sandwich construction knitted fabric and use fibre such as underwear, sportswear, bedding of this knitted fabric etc., this knitted fabric has excellent hygroscopicity, comfortableness while wearing is excellent, even if be also not easy to feel feeling of oppression and heat during due to perspirations such as motions, when perspiring, though when perspiring quite in large quantities, be also not easy to feel sweat sticky feeling, soak sense, a cool feeling, and pro-skin sense, outward appearance are good.
Background technology
The cellulose-based materials such as cotton, copper ammonia fibre have excellent hygroscopicity, water imbibition, while using as clothes, generally when there is no the state (insensible perspiration) of perspiration or perspiring on a small quantity as snug as a bug in a rug.Yet volume of perspiration surpasses about 100g/m when summer or motion 2time, because cellulose-based material easily keeps the sweat absorbing, therefore, easily there is so-called sticky feeling, post exercise is sent out cool feeling.Especially, in volume of perspiration, surpass about 200g/m 2time, described sticky feeling, to send out cool feeling very serious, and it is very uncomfortable that wearer can feel.
As for preventing this sticky feeling, send out the method for the sense of discomfort that cool feeling causes so that sweat is transferred to outside from the skin side of clothes, allowing moisture not residue in skin side is target, has carried out the research of various cloth and silks.It is to use hydrophobic fibre in skin side mostly, and has proposed to allow the single thread fiber number, cross sectional shape of the yarn that uses in the outside of the knitted fabric various schemes such as cloth and silk different with inboard.
For example, in following patent documentation 1 and patent documentation 2, knitted fabric has been proposed, it uses the fiber of water absorbing capacity excellence by the outside at knitted fabric, in the inboard of knitted fabric (skin side), use the poor fiber of water absorbing capacity, form moisture and do not residue in the structure of knitted fabric inboard, thereby suppressed sticky feeling, a cool feeling.
In patent documentation 1, owing to using the poor fiber of water absorbing capacity at knitted fabric inboard (skin side), therefore not talkative absorbing sweat ability is abundant, in addition, as the fiber of water absorbing capacity excellence, use cotton grade for staple fibre, therefore, the ability of the sweat that diffusion absorbs is also poor, and the effect of the minimizing of being clamminess is insufficient.
On the other hand, in patent documentation 2, as the high fiber of water absorbing capacity, use cellulosic filaments, therefore, the ability of diffusion is excellent, but owing to using hydrophobic fiber at knitted fabric inboard (skin side), therefore, the ability of absorbing sweat is insufficient.
In addition, in following patent documentation 3, also disclose and arranged concavo-convex at knitted fabric inboard (skin side), and at this protuberance configuration polyester filament fiber, at the knitted fabric of the gluing filament fiber of recess arrangement, because the protuberance with skin contact is hydrophobic fibre, therefore, with patent documentation 1 and patent documentation 2 in the knitted fabric recorded exist equally the ability of absorbing sweat insufficient.
In addition, the knitted fabric that contains hydrophilic fibre at knitted fabric inboard (skin side) is disclosed in patent documentation 4.In patent documentation 4, disclose and used the knitted fabric being formed by hydrophilic fibre and hydrophobic fibre, make the line density (course density) of knitted fabric inboard (skin side) be greater than the line density in knitted fabric outside, at knitted fabric inboard (skin side), arrange concavo-convex, thereby there is the knitted fabric of the dry feeling of skin.
Therefore yet this knitted fabric is that the blending ratio of high density and hydrophilic fibre is very high, is 25～75%, at skin side water conservation, even if having concavo-convexly, sticky feeling is also larger, as the scaly dry skin of dress material purposes, is inadequate.
Like this, while being still necessary to provide from insensible perspiration or while perspiring on a small quantity during to a large amount of perspiration, without sultry, can suppress sticky feeling, send out the comfortable knitted fabric of cool feeling.

The specific embodiment
Below describe the present invention in detail.
Knitted fabric of the present invention is the knitted fabric that at least contains the cellulose-based long fiber of 5～25 % by weight and 75～95 % by weight synthetic fiber.That is,, in knitted fabric of the present invention, cellulose-based long fiber accounts for 5～25 % by weight of all knitted fabrics, preferably 5～20 % by weight.
In this manual, cellulose-based long fiber has the natural fabric prime system long fibers such as regenerated fiber prime system long fiber, the silks such as artificial silk, copper ammonia fibre, acetate fibre etc., and it is not particularly limited.It is few that the short fiber of cellulose such as these fibers and cotton, regenerated cellulose staple fibre are compared fluffing, yarn surface smoothing, so the diffusivity of moisture is high.Wherein, preferred regenerated fiber prime system long fiber, in the middle of regenerated fiber prime system long fiber, artificial silk long fiber, cuprammonium long fiber are compared with the cotton of raw material, and the moisture rate of fiber is also large, and moisture sorption effect is large, is therefore preferred.Especially, cuprammonium long fiber is compared with artificial silk long fiber, and the surface configuration of each root fiber is also level and smooth, and fiber number is also thinner, and very soft during therefore for knitted fabric, feel is good, is therefore particularly preferred.By these fibers are configured in knitted fabric effectively, can make hygroscopicity and the effect that reduces of being clamminess is excellent, during from insensible perspiration or while perspiring on a small quantity to a large amount of perspiration, without sultry, nothing, be clamminess, comfortable knitted fabric while wearing.When the cellulose-based long fiber content all with respect to knitted fabric is less than 5%, hygroscopicity is little, the ability of the sweat of absorption gaseous state during insensible perspiration or while perspiring is on a small quantity inferior, in addition, the water suction that cellulose-based long fiber produces and move water-based and also become insufficient, the minimizing effect that is clamminess in the time of can not expecting to perspire, the comfortableness of knitted fabric when wearing is poor.On the other hand, when cellulose-based long stapled this content surpasses 25%, the cool feeling after being clamminess, perspiring during following perspiration becomes significantly, so the comfortableness of knitted fabric when wearing is poor.
Cellulose-based long stapled fiber number is not particularly limited, is preferably approximately 22～approximately 84 dtexs (dtex), more preferably approximately 33～about 56dtex.Cellulose-based long stapled single thread fiber number is not particularly limited, from the viewpoint of pro-skin sense, feel, considers, be preferably approximately 0.5～about 2dtex.
Cellulose-based long fiber is contained sometimes in knitted fabric, can make the use that interweaves of long fiber, the staple fibre of cellulose-based long fiber and polyester system, the synthetic fiber such as polyamide-based, but the viewpoint of processing from sweat is considered, preferably, as the synthetic fiber such as cellulose-based long fiber and polyester system or polyamide-based long fiber, the long stapled composite yarn of synthetic fiber and being configured in knitted fabric especially.Compound tense, is preferably the multifilament of the long stapled fiber number of synthetic fiber approximately 22～about 84dtex, single thread fiber number approximately 0.5～about 2dtex, makes not destroy pro-skin sense.Cellulose-based long fiber is preferably 1:3～2:1 with the ratio of the compound long stapled fiber number of synthetic fiber.The viewpoint that the sweat being undertaken by diffusion when perspiring is processed considers, synthetic fiber long fiber is preferably profiled-cross-section, and W type cross-section fibers is owing to being special-shaped and flat, meet based on capillary sweat process and flexibility the two, so be preferred.
The long stapled composite yarn of cellulose-based long fiber or cellulose-based long fiber and synthetic fiber and other fiber interweavings and be configured in knitted fabric.Interweave and coordinate the preferably long fiber of synthetic fiber of yarn, especially polyester system or polyamide-based long fiber, the preferably multifilament of fiber number approximately 16～about 170dtex, single thread fiber number approximately 0.5～about 2dtex.Also can suitablely interweave polyurethane fiber and give knitted fabric draftability.The multifilament that the present invention uses can also contain antioxidant, fire retardant, antisatics, pigment, fluorescent whitening agent, infrared absorbent, the defoamers etc. such as the slip agents such as the crystallization nucleating agents such as the ultra-violet absorbers such as the stabilizing agents such as the delustering agents such as titanium dioxide, phosphoric acid, hydroxyl benzophenone derivant, talcum, Aerosil, hindered phenol derivative.
The raw material that use in knitted fabric of the present invention can have curling, and from the viewpoint of pro-skin sense, preferably crimp extension rate is 0～150%.It should be noted that, the percentage elongation that batches of false twist yarn is measured according to following condition.
The upper end of batching yarn is fixed, and lower end applies 1.77 * 10 -3the load of cN/dt, measures the length (A) after 30 seconds.Then, remove 1.77 * 10 -3the load of cN/dt, applies the load of 0.088cN/dt, measures the length (B) after 30 seconds, and (1) obtains crimp extension rate according to the following formula.
Crimp extension rate (%)={ (B-A)/A } * 100 (1)
As mentioned above, knitted fabric of the present invention is the knitted fabric that at least contains the cellulose-based long fiber of 5～25 % by weight and 75～95 % by weight synthetic fiber.That is, in knitted fabric of the present invention, can contain the fiber except this cellulose-based long fiber and synthetic fiber.Yet these synthetic fiber are 75～95 all % by weight of knitted fabric, are preferably 80～95 % by weight.
Knitted fabric of the present invention is characterised in that, in a surface A, degree of depth 0.13mm be take and cellulose-basedly in interior region long stapledly occurred that the area of part is 0.2～15% with respect to all areas of knitted fabric, is preferably 0.5～10%.Herein, degree of depth 0.13mm refers to the outermost layer in surface A with interior region, and this layer directly contacts with the sweat of skin, absorbs sweat.By being formed on, in this layer, configure a small amount of cellulose-based long fiber, a large amount of cellulose-based long stapled tilted configuration structures of configuration in the interior layer of knitted fabric, with at knitted fabric skin face, settle the existing knitted fabric of 100% synthetic fiber to compare, absorb fast sweat, by the cellulose-based long fiber of tilted configuration, brute force attracts sweat to knitted fabric interior layer, in addition, and by cellulose-based long stapled diffusivity, do not make sweat be detained, and make it to be diffused in knitted fabric on a large scale.Like this, the sweat of skin is drawn in knitted fabric fast and in large quantities, thereby can improves being clamminess while wearing tremendously.In addition, cellulose-based long fiber also has excellent water diffusivity, and therefore, easily, in the diffusion of interior layer generation water, the sweat of diffusion is diffused to the outside of humidity lower than skin side.
For the outermost layer from knitted fabric is to the cellulose-based long fiber of interior layer tilted configuration, the cellulose-based long fiber blending ratio that described knitted fabric is all is made as X(% by weight) and cellulose-basedly long stapledly occur that ratio is made as Y(area % by outermost) time, preferred X > Y, more preferably (2/3) X > Y, particularly preferably (1/2) X > Y.In the present invention, the cellulose-based long fiber blending ratio in the cellulose-based long fiber occurrence rate of such outermost surface is all lower than knitted fabric is designated as cellulose-based long fiber tilted configuration.
Wherein, consider cellulose-based long stapled proportion approximately 1.5, the proportion of synthetic fiber is conventionally than this little (general polyester fiber approximately 1.4, polyurethane fiber approximately 1.2, polyamide-based fiber approximately 1.1), in outermost cellulose-based long stapled appearance amount ratio Yw(% by weight) with the relation of X in, preferred X > Yw, further preferred (2/3) X > Yw, more preferably (1/2) X > Yw.
Now, Yw can obtain with following formula (2).
Yw＝Y·D 1/｛X·D 1+（100-X）·D 2｝ （2）
In formula, D 1cellulose-based long stapled proportion, and D 2it is the mean specific gravity of the fiber beyond cellulose-based long fiber.｝
Knitted fabric of the present invention is owing to configuring a small amount of cellulose-based long fiber in the surface A with skin contact, thereby also has excellent pro-skin sense.In addition, owing to thering is excellent hygroscopicity, also can suppress feeling of oppression and heat.
In order further to improve the minimizing effect that is clamminess of knitted fabric of the present invention, can in surface A, bestow concavo-convex knit stitches.The difference of the height of protuberance and recess is approximately 0.13～about 0.50mm preferably.In addition, in surface A, particularly, preferably, there is more than 10 protuberances while measuring in test portion arbitrarily 1cm * 1cm scope in protuberance equal distribution in any one above-mentioned scope, and protuberance area is preferably 10～70% left and right of surface area.As bestowing concavo-convex method, can list knit stitches is made an effort and enrolled the method for tuck stitch, rib stitch; At protuberance by the overlapping method of yarn; Change the method for yarn fiber number etc.
Concavo-convex by applying on the surface of knitted fabric, contact cold warming and diminish, thereby while using this face as skin face, can further alleviate being clamminess while perspiring.When the difference of the height of protuberance and recess is less than about 0.13mm, with the contact area of skin with do not have irregular situation not compare to change, therefore, do not claim to have concavo-convex, can not expect the further minimizing effect of the sticky feeling of knitted fabric.If more than the about 0.13mm of the difference of the height of protuberance and recess, using the irregular side of the tool of knitted fabric, the skin when skin face is worn and the contact area of knitted fabric tail off, and when knitted fabric absorbs moisture, the attenuating effect of sticky feeling is larger.On the other hand, when the difference of the height of protuberance and recess surpasses about 0.50mm, larger as fabric thickness, because of concavo-convex increases of hardening causing, in addition, and owing to having air layer and exist the situation of the infringement wearing feeling of sultry grade, thus not preferred.
In addition, if the difference of the height of protuberance and recess surpasses 0.13mm, existing and not being included in the above-mentioned degree of depth from surface is the region in the region below 0.13mm.That is, in this case, for surface A, can be divided into the region (hereinafter referred to as the internal layer of surface A) that region (hereinafter referred to as the outermost layer of surface A) below degree of depth 0.13mm and the degree of depth surpass 0.13mm.The area occupied of the knitted fabric protuberance in the outermost layer of surface A, be preferably surface A the gross area 10～70%.
The difference of the height of protuberance and recess is by the cross-section photograph of the shooting knitted fabrics such as electron microscope, in 5 places, measures and averages.The difference of protuberance and recess is 0.17～about 0.45mm more preferably from about.
Mode by the skin side according to being wearer by the surface A of knitted fabric of the present invention is disposed at fibre, the effect that the suitable knitted fabric that embodies the invention described above is brought into play.
Knitted fabric of the present invention is characterised in that, the giving and 200g/m of surface A 2the cold coefficient of conductivity of contact approximately 180～about 330W/m during moisture 2℃.This contacts the preferred approximately 180～280W/m of the cold coefficient of conductivity (below also referred to as contact coldness value) 2℃, 180～about 260W/m more preferably from about 2℃, further preferred approximately 180～about 240W/m 2℃.
The mensuration that contacts the cold coefficient of conductivity is used KATO TECH CO., the Thermo Lab II that LTD. manufactures.This device is determined on test portion the hot transmission capacity while placing the electric hot plate being heated.Concrete assay method is as described below.
By the test portion for measuring 20 ℃, 65%RH(relative humidity) environment under after damping 24 hours, get the sample of 8cm * 8cm, measure the maximum heat transfer amount that the electric hot plate that is heated to 30 ℃ under 20 ℃, 65%RH environment is positioned over to the moment on the knitted fabric sample that knitted fabric surface A arranges upward.
Give and 200g/m 2moisture during moisture is the condition of the amount of moisture of the imagination sweat that cloth and silk absorbs when as considerable in perspiration motion.
Moisture method of administering same during mensuration is, in the surface A side utilization of test portion, sprays to the reach+1.28g of weight making with moisture with the test portion of the size sampling of 8cm * 8cm.The inner water temperature of now spraying is 20 ℃.
While remaining moisture in knitted fabric, because the thermal conductivity factor of water is high, therefore, from electric hot plate, capture in large quantities heat, contact the cold coefficient of conductivity and increase.That is, contact the test portion that the cold coefficient of conductivity is large and mean that sticky feeling is large, surpass about 330W/m 2℃ time, sticky feeling is very large, therefore not preferred, on the other hand, lower than about 180W/m 2℃ time, therefore because sticky feeling is little, be preferred, but for the cold coefficient of conductivity of contact is set as lower than about 180W/m 2℃, need to enlarge markedly concavo-convexly, from the viewpoint of pro-skin sense, consider it is not preferred.It should be noted that, existingly contain cellulosic knitted fabric and conventionally substantially exceed about 330W/m 2℃, and in the present invention, by configure cellulose-based long fiber in knitted fabric medium dip, utilize cellulose-based long stapled water suction, diffusivity, even if formed under the state to large quantity of moisture, also can improve the knitted fabric of being clamminess property.
The thickness of knitted fabric of the present invention is approximately 0.5～about 1.2mm preferably.
The thickness of knitted fabric can obtain as follows: the thickness measuring instrument that uses Peacock company to manufacture, and with the load of 5g, the determination part of φ 3.0cm is contacted with knitted fabric, measure 3 local thickness and average.When thickness is less than about 0.5mm, sweat treatability is not enough, is difficult to obtain comfort, and on the other hand, when thickness surpasses about 1.2mm, the hardness of cloth increases, and destroys pro-skin sense.The thickness of knitted fabric of the present invention is 0.5～about 1.0mm more preferably from about.The present invention is by cellulose-based long stapled water suction, diffusivity, draw rapidly the sweat of skin, therefore, with 100% polyester, according to surface and density contrast, the fiber number of the inside are poor, attempt to lower the knitted fabric comparison of being clamminess, even also can bring into play the effect of same degree for thinner knitted fabric.
