Description
本發明,是關於一種透液性纖維不織布,更詳而言之,是關於作為用後即棄式紙尿褲或生理用衛生棉等的用後即棄式體液吸收性物品的表面薄片使用適合的纖維不織布。
以往,由熱可塑性合成樹脂的短纖纖維所形成的透液性纖維不織布已為眾所周知。例如日本特開2009-30218號公報(專利文獻1)中,揭示一種這種的不織布,在表面形成有彼此平行朝機械方向延伸的凸條部與凹條部,其凸條部與凹條部相對於機械方向交替排列在交叉方向,裏面平坦地形成。
[專利文獻1]日本特開2009-30218號公報(JP2009-30218A)
專利文獻1記載的不織布,是由:相對於被載置在網板朝機械方向行走的纖維網的表面,從以所需要的間距被配置在交叉方向的複數個噴嘴噴射加熱空氣的方式所製造。在其纖維網,形成有位在噴嘴正下方的部分的凹條部,在與比鄰的噴嘴和噴嘴之間的部分形成有凸條部。在該不織布,將這個作為被覆體液吸收性物品的體液吸收性芯材的表面薄片來使用時,凹條部是形成其底部的密度比凸條部的密度變的更高,而可獲得體液從凸條部朝向凹條部迅速的移行。然而,在這樣子的凹條部,如經血的黏稠的體液無法迅速透過表面薄片,而有容易殘留在底部的表面的傾向。
於此,在本發明,是以對以往的透液性纖維不織布施行改良作為課題,而獲得即使是黏稠的體液也可迅速透過表面薄片的凹條部。
為了解決前述課題,本發明的對象是一種,具有彼此正交的縱向與橫向和厚度方向,前述厚度方向形成有在前述縱向與前述橫向展開的表面與位在其相反面的裏面,在前述表面彼此平行朝前述縱向延伸的凸條部與凹條部是朝前述橫向交替排列,前述裏面實際上形成平坦,由熱可塑性合成樹脂所形成的短纖纖維為彼此熔接的狀態之透液性纖維不織布。
這種透液性纖維不織布中,作為本發明的特徴之處為以下所述。相對於從前述裏面到前述凸條部的頂部為止的厚度T,從前述裏面到前述凹條部的底部為止的厚度t在40~60%的範圍內,在前述短纖纖維使用跨前述凸條部及於與前述凸條部的兩側鄰接的前述各凹條部者。
本發明的實施形態之一,其中,跨前述凸條部的前述短纖纖維,在前述鄰接的各凹條部,熔接在與該短纖纖維不同的短纖纖維。
本發明的實施形態的另一個,其中,質量在15~35g/m2的範圍內。
本發明的實施形態的另一個,其中,前述凸條部的比容積在70~105cc/g的範圍內,前述凹條部的比容積在40~60cc/g的範圍內。
本發明的實施形態的另一個,其中,在前述短纖纖維使用看起來的纖維長在10~80mm者。
本發明的實施形態的另一個,其中,前述凸條部與前述凹條部是由:讓含有所需要的每平方公尺的質量的由前述熱可塑性合成樹脂所形成的前述短纖纖維的纖維網連續朝機械方向行走,且是藉由從相對於前述機械方向,朝交叉方向間歇性地配置的複數個噴嘴朝向前述網狀物噴射加熱空氣的方式所形成,前述凸條部在前述交叉方向,被形成在比鄰的前述噴嘴彼此之間,前述凹條部被形成在前述噴嘴的正下方。
本發明的透液性纖維不織布,由於是在纖維不織布的表面含有:隔著凸條部,延伸於比鄰的凹條部彼此之間的短纖纖維,且是在各凹條部,熔接在與其短纖纖維不同的短纖纖維者,所以即使作為表面薄片被使用的纖維不織布的表面與肌膚而摩擦到凸條部時,也可抑制其表面的起毛。又,凹條部的厚度t是凸條部的厚度T的40~60%,透液性纖維不織布與凸條部相較,凹條部是只有被稍微壓縮的程度,在凸條部與凹條部於比容積不會產生極端的差異,所以如經血這種黏稠的體液,即使在凸條部在凹條部,皆可迅速透過纖維不織布。
參照添附的圖面,說明本發明的透液性纖維不織布的詳細是如以下所述。
圖1為透液性纖維不織布1的立體圖。纖維不織布1是藉由將熱可塑性合成樹脂的短纖纖維2彼此予以熔接的方式所形成者,具有彼此正交的縱向A與橫向B和厚度方向C。在厚度方向C形成有在縱向A與橫向B展開的表面3、與位在表面3相反面的裏面4。在表面3形成有彼此朝縱向A平行延伸的複數個凸條部6與複數個凹條部7,該等凸條部6與凹條部7在橫向B交替排列。裏面4實際上形成平坦。
凸條部6是位在表面3,且具有自裏面4起的高度為最高的位置的頂部11,在凸條部6彼此之間,從裏面4至頂部11為止的尺寸T,亦即凸條部6的高度幾乎一定。朝橫向B反覆所形成的凸條部6的間距P為比鄰的頂部11與頂部11之間的距離,且在凸條部6彼此之間幾乎一定。
凹條部7是位於表面3,且具有自裏面4起的高度為最低的位置的底部12,在凹條部7彼此之間,從裏面4至底部12為止的尺寸t,亦即底部12的高度幾乎一定。朝橫向B反覆形成的凹條部7的間距為與間距P相等之比鄰的底部12與底部12之間的距離。
纖維不織布1是作為用後即棄式紙尿褲或生理用衛生棉、失禁患者用襯褲等的體液吸收性物品的透液性表面薄片使用適合者。其表面薄片為被覆體液吸收性的芯材者,是假設會與體液吸收性物品的使用者的肌膚接觸被使用者。這種纖維不織布1中,在短纖纖維2纖度為1~8dtex,看起來的纖維長為10~80mm的熱可塑性合成纖維,並使用經過親水化處理者。於此,所謂看起來的纖維長是指,依據日本工業規格((JIS)L1015:1999的段落8.4、c)項的規定所測定的值。測定了看起來的纖維長的短纖纖維2,是為了投入後述圖2、5所例示的梳棉機101所準備者,且為投入前完成必要的捲縮處理等的所有的處理者。測定用所採取的短纖纖維2是一面不對其施加伸長力,一面調整其形狀使其在丈量時幾乎成為直線狀。作為短纖纖維2,又為了可以比較低的溫度使短纖纖維2彼此熔接;與賦予纖維不織布1對於厚度方向的壓縮變形的適當的彈性恢復力,最好使用複合短纖纖維。在其複合短纖纖維可使用並列型者也可使用芯鞘型者,若為芯鞘型者,則例如鞘成分能使用如聚乙烯這種熔融溫度低的熱可塑性合成樹脂,芯成分能使用比鞘成分的熔融溫度具有高熔融溫度之聚丙烯或聚酯等的熱可塑性合成樹脂者。
纖維不織布1為每平方公尺的質量相同者,其質量在15~35g/m2的範圍。凸條部6是厚度T在0.5~5mm的範圍,間距P在2~8mm的範圍。凹條部7,其厚度t在厚度T的25~60%的範圍。纖維不織布1的表面3的短纖纖維2含有:複數條隔著凸條部6,從比鄰的一方的凹條部7延伸到另一方的凹條部7者,亦即,使含有複數條圖中以粗度被誇大的短纖纖維2a跨過例示的凸條部6,而從一方的凹條部7延伸到另一方的凹條部7。短纖纖維2除了為彼此機械性地交絡之外,為彼此熔接者,但在表面3呈現如短纖纖維2a的這種狀態者,其在比鄰的凹條部7與凹條部7,尤其是在凹條部7的底部12,熔接在與短纖纖維2a交叉的其他的短纖纖維2時,即使位在比鄰的凹條部7與凹條部7之間的凸條部6的頂部11,因肌膚而被摩擦時,也能抑制短纖纖維2a在凸條部6起毛的情況。又,即使表面3之中,在比較不易與肌膚接觸的底部12,短纖纖維2彼此熔接的情況也能達到防止在其熔接的部分,發生所謂刺激肌膚的問題的效果。表面3的起毛,雖可能使表面3成為肌膚觸感不均的原因或成為使經血等的體液容易滯留的原因,但短纖纖維2a的態樣在消除該等的原因上也具有效果。在纖維不織布1,為了獲得達成短纖纖維2a這種的作用,在短纖纖維2使用看起來的纖維長比間距P更長者,更理想為使用比間距P的兩倍更長者,以使其即使在一面畫成螺旋形狀或鋸齒形狀一面延伸的狀態,也可跨凸條部6,從比鄰的一方的凹條部7延伸到另一方的凹條部7。
圖2表示纖維不織布1的製造工程的一例的圖。在工程I,藉由梳棉機101將短纖纖維2的集合體予以開纖做成網狀物102。在梳棉機101的上游,也可在短纖纖維2混合適合的混合用短纖纖維112。短纖纖維2最好是預先賦予機械性的捲縮,而可促進藉由梳棉機101的開纖處理。作為混合用短纖纖維112,短纖纖維2有熱可塑性合成樹脂的種類不同者或纖維長不同者、纖度不同者等。混合用短纖纖維112是在沒有超過網狀物102的每平方公尺的質量的40質量%的範圍使用。
在工程II,網狀物102是藉由加熱空氣噴射手段210被處理。手段210是形成纖維不織布1的凸條部6與凹條部7用者,包含:朝機械方向MD旋轉的吸筒200、與加熱空氣噴射用的第1、第2、第3噴嘴集合體211、212、213。第1、第2、第3噴嘴集合體211、212、213各包含有:第1、第2、第3噴嘴分歧管211a、212a、213a的各噴嘴分歧管、與單體噴嘴211b、212bb、213b的各單體噴嘴。第1、第2、第3噴嘴分歧管211a、212a、213a是朝向吸筒200的軸向,亦即相對於機械方向MD朝交叉方向CD(參閱圖3)延伸者,且是朝吸筒200的周向分開所需的間隔被配置。第1、第2、第3單體噴嘴211b、212b、213b分別相對於第1、第2、第3噴嘴分歧管211a、212a、213a的各噴嘴分歧管,在交叉方向CD以所需的間距被安裝,而從吸筒200的周面分開所需尺寸。一個例子是在第1、第2、第3噴嘴集合體211、212、213的各噴嘴集合體,第1、第2、第3單體噴嘴211b、212b、213b朝交叉方向CD以一定的間距,例如以4mm的間距排列,且在機械方向MD排列在同一線上。第1、第2、第3噴嘴集合體211、212、213,是可從第1、第2、第3單體噴嘴211b、212b、213b的各單體噴嘴以所需的風量噴射所需溫度的加熱空氣。在第1、第2、第3單體噴嘴211b、212b、213b,可使用例如口徑0.5~2.5mm的噴嘴。
吸筒200是將透孔223(參閱圖4)一樣地形成在其周面,其透孔223與吸筒200的吸入機構(未圖示)連接。在周面的一個例子,直徑0.2~1mm的透孔223形成15~30%的開孔率。吸筒200的周速與網狀物102的搬運速度相同。
在工程II,第1、第2噴嘴集合體211、212,是在進行第3噴嘴集合體213所為之網狀物102的處理之前,用來壓縮從梳棉機101出來呈膨鬆的狀態的網狀物102,且使表面成為平滑的狀態。因此,自第1、第2噴嘴集合體211、212噴出的加熱空氣的溫度與壓力是被設定成:在不會熔融短纖纖維2及混合用短纖纖維112的程度下予以軟化,使空氣的噴射壓作用在被軟化的短纖纖維2、112,將網狀物102壓縮到其厚度成為1/2~1/4左右,且使網狀物102的表面成為平滑的狀態。來自第3噴嘴集合體213的加熱空氣,其溫度與壓力被設定成,可在被壓縮且成平滑的狀態的網狀物102形成凹條部7的同時,可使凹條部7中的短纖纖維2之中的至少一部分的短纖纖維彼此熔接。
藉由來自工程II的第1、第2噴嘴集合體211、212的加熱空氣的作用,網狀物102的表面因短纖纖維2的起毛等造成的凹凸減少而變得平滑,其結果,纖維不織布1的表面3變得光滑而成為肌膚觸感佳的不織布。來自第3噴嘴集合體213的加熱空氣壓縮位在第3單體噴嘴213b正下方的的部分,而形成纖維不織布1的凹條部7時,在網狀物102之中,位在第3單體噴嘴213b與第3單體噴嘴213b之間的部分形成有凸條部6。其凸條部6,在形成凸條部的時候,由於網狀物102因第1、第2噴嘴集合體211、212的作用變成平滑者,而容易使得自網狀物102的裏面起的尺寸的凸條部6的高度成為一樣。凹條部7也因為與凸條部6同樣的理由,而容易形成一樣的深度,換言之自網狀物102的裏面起的尺寸容易形成一樣。從工程II出來的網狀物102被載置在網狀輸送帶往機械方向MD搬運。
在工程III,將設定成可使短纖纖維2的表面熔融的溫度的加熱空氣吹向網狀物102,使短纖纖維2彼此、或短纖纖維2與混合用短纖纖維112熔接,使纖維不織布1的耐摩擦性提升。
在工程IV,將冷卻到室溫的網狀物102捲取作成纖維不織布1。
圖3為第1噴嘴集合體211的立體圖。在第1噴嘴集合體211含有:朝吸筒200的軸向,亦即朝交叉方向CD延伸的第1噴嘴分歧管211a、與以所需的間距被安裝在第1噴嘴分歧管211a的複數個第1單體噴嘴211b。各第1單體噴嘴211a,是可朝向吸筒200的周面噴射加熱空氣。雖然第1噴嘴分歧管211a還在其上游部安裝有壓力調整閥與加熱器,但該等的圖示被省略。在獲得圖1的纖維不織布1用的圖2的製造工程,第2、第3分歧管212a、213a與第2、第3單體噴嘴212b、213b,是與第1噴嘴集合體211的第1分歧管211a和第1噴嘴單體211b同樣地被形成。在各噴嘴集合體211、212、213之間,雖然第1、第2、第3單體噴嘴211b、212b、213b口徑相同,朝交叉方向CD排列的間距也相同為理想,但也可以該等口徑或間距不同的態樣組裝圖2的製造工程。
圖4為形成吸筒200的周面的金屬板201的部分圖。在金屬板201形成有與吸筒200的吸入機構連接的複數個透孔223。透孔223是孔徑例如在0.2~1mm之間者,在各吸筒200的周向與軸向以所需的間距排列。
圖5是與表示纖維不織布1的製造工程的其他的例子的圖2同樣的圖。在圖5的工程I,藉著梳棉機101將短纖纖維2的集合體開纖而作成網狀物102。在梳棉機101的上游,可在短纖纖維2混合適合的混合用短纖纖維112。短纖纖維2是最好預先賦予機械性的捲縮,而可促進梳棉機101所為之開纖處理。混合用短纖纖維112是與圖2相同。
在圖5的工程II,在烘乾機251,將設定成可使短纖纖維2的表面熔融的溫度的加熱空氣吹向載置在網狀物用輸送帶253的網狀物102,使短纖纖維2彼此、或短纖纖維2與混合用短纖纖維112予以熔接。
在圖5的工程III,對在工程II被加熱,且被載置在網狀物用輸送帶253呈加熱狀態的網狀物102,從噴嘴集合體252的複數個單體噴嘴252b進行所需量噴射所需溫度的加熱空氣。複數個單體噴嘴252b,是以所需的間距被安裝在與機械方向MD正交朝交叉方向延伸的噴嘴分歧管252a,作為形成纖維不織布1的凹條部7與凸條部6來使用。噴嘴集合體252的一個例子中,單體噴嘴252b是以4mm的間距被安裝在噴嘴分歧管252a,且口徑具有0.5~2.5mm。
在圖5的工程IV,將冷卻的網狀物102巻取作成纖維不織布1。
在圖5使用的網狀物用輸送帶253的理想的一例為平織具有18~30網孔者。為不足18網孔的網狀物用輸送帶,則所得的纖維不織布1為粗糙的不織布,且會在纖維不織布1的裏面4留下形成網孔的線材的痕跡,使裏面4不易形成平滑。又,在超過30網孔的網狀物用輸送帶,則即使是在工程II、工程III,加熱空氣的透過性皆不佳,且在網狀物102的裏面,使短纖纖維2彼此適當熔接困難。
在圖5的工程,由於是在工程III處理網狀物102時,使短纖纖維2彼此或短纖纖維2與混合用短纖纖維112熔接,所以藉由噴嘴集合體252做成凸條部6與凹條部7容易。因此,在圖5的工程,不用使用圖2的第1~第3噴嘴集合體211、212、213,只要使用一台的噴嘴集合體252便已足夠。又,來自噴嘴集合體252的加熱空氣,可將其風量減少到5.0~12.0Nl/m2或將溫度降到比200℃更低。
根據發明者的觀察,使用圖2或圖5例示的工程所獲得的纖維不織布1中,在纖維不織布1的表面3,短纖纖維2是跨凸條部6,並且延伸到被形成在其各凸條部6的兩側的凹條部7的底部12,在底部12,使其短纖纖維2與其他的短纖纖維2或混合用短纖纖維112熔接,而具有抑制表面3在進行後述的摩擦試驗時,起毛發生的傾向。在其摩擦試驗,施加在表面3的摩擦,主要是作用在凸條部6的頂部11附近,但位在其頂部11的短纖纖維2,在被形成在各凸條部6的兩側的凹條部7的底部12,藉著與其短纖纖維2不同的其他的短纖纖維2或混合用短纖纖維112的熔接方式,能抑制在頂部11的起毛。
能抑制起毛的發生的其傾向,是固定從圖2的第3噴嘴集合體213噴射的加熱空氣的溫度的情況下,使風量改變時,風量多的話則凹條部7的深度愈深,換言之,圖1的厚度t愈小變的愈顯著。尤其是,在凹條部7的厚度t為厚度T的60%以下的纖維不織布1,起毛減少到作為用後即棄式紙尿褲或生理用衛生棉的表面薄片可容許的程度。但是,凹條部7是厚度t愈小,亦即,深度愈深,底部12的密度愈高,比容積有變小的傾向。以具有比容積小的凹條部7的纖維不織布1作為生理用衛生棉的表面薄片來使用時,則如經血這種黏稠的體液,在凹條部7的底部12,沒有被迅速吸收到芯材,而滯留在底部12的傾向變強,且會因滯留的經血污染肌膚的情形,或廢棄生理用衛生棉時,容易看見殘留在表面薄片的經血的情況。然而,本發明的纖維不織布1,是藉由將從裏面4到凹條部7的底部12為止的高度之厚度t保持在從裏面4到頂部11為止的高度的厚度T的40%以上,而使凹條部7的比容積與凸條部6的比容積比較不會極端地變低,而可小幅抑制在纖維不織布1的表面3的體液的滯留面積。
製作使相對於凸條部6的厚度T的凹條部7的厚度t的比例改變後的複數種類的纖維不織布作為實施例的纖維不織布,並使用人工經血作為體液,評價在含有凹條部7的表面3的體液的滯留面積與表面3的摩擦強度。並且,也製作作為相對於實施例的比較例的纖維不織布,針對其纖維不織布,也測定體液的滯留面積、與表面的摩擦強度並進行評價。該等的評價結果如表1~4所示。具有凸條部6與凹條部7的纖維不織布1的厚度T與厚度t的測定方法、體液的滯留面積的測定方法、摩擦強度的評價方法是如以下所述。

網狀物的每單位面積的加熱空氣噴射量:
10.92~19.17Nl/m2
此外,各噴嘴集合體的單體噴嘴,是將間距設定在4mm,在噴嘴集合體彼此間,將單體噴嘴彼此在機械方向設定成列。又,吸筒的周面的透孔的開孔率設定在22.16%。
3. 通過工程II的網狀物是送到工程III,在工程III與溫度135℃的加熱空氣接觸5秒,使短纖纖維彼此熔接,之後,將網狀物冷卻至室溫,而獲得實施例1~10的纖維不織布。
實施例1~10的纖維不織布的評價結果,是如表1~3所記載。表1~3及後述表4的凸條部與凹條部的比容積是藉由下述的程序(1)、(2)所求出的值。
(1)由下式求出從10cm×10cm的纖維不織布片10片的平均質量至每平方公尺的質量。然而,本發明中,使用比該纖維不織布片更小的纖維不織布片也可求出質量。
質量(g/m2)=(平均質量(g))÷0.01
(2)針對求出比容積的纖維不織布片,測定凸條部的頂部的厚度T與凹條部的底部的厚度t,並利用下式求出比容積。
凸條部或凹條部的比容積(cc/g)=((凸條部的厚度T或凹條部的厚度t)×1000)÷質量(g/m2)
除了將圖2的第3噴嘴集合體的加熱空氣噴射量設定在8.17~24.58Nl/m2以外,採用與實施例相同的條件,製造比較例1~18的纖維不織布,並與實施例同樣進行評價。評價的結果如表1~4所記載。
表1~4中,
(1)質量在15~35g/m2時,當厚度的比t/T在40~60%的範圍內時,纖維不織布的體液的滯留面積比較小。亦即,作為體液所使用的黏稠的人工經血,在實施例的纖維不織布不會有大範圍擴散的情況,透過纖維不織布,移行到作為吸收體的替代物所使用的濾紙迅速。
(2)t/T為超過60%的比較例的纖維不織布,相對於摩擦的抵抗力低,容易起毛。t/T為60%以下的纖維不織布有不易起毛的傾向。
(3)由纖維不織布的比容積來看,凸條部的比容積在70~105cc/g的範圍,凹條部的比容積在40~60cc/g的範圍的實施例的纖維不織布,不會有讓黏稠的體液滯留的情形,且不會有因摩擦就簡單起毛的情況。
圖7是針對實施例7與比較例7的纖維不織布例示測定體液的滯留面積用的程序用的圖。在圖7,顯示滯留在該等的例子的纖維不織布的體液的畫像、將其畫像二值化的結果、從其結果求出關於體液的畫素與面積、畫素與面積的平均值。
