纖維加工劑、及含有其之液體通透性不織布Fiber processing agent and liquid-permeable nonwoven fabric containing the same

本發明係關於一種可對不織布賦予優異之回滲性及反覆透水性之纖維加工劑、含有該纖維加工劑之液體通透性不織布、以及使用有該液體通透性不織布之衛生材料。The present invention relates to a fiber processing agent capable of imparting excellent permeability and repeated water permeability to a nonwoven fabric, a liquid-permeable nonwoven fabric containing the fiber processing agent, and a sanitary material using the liquid-permeable nonwoven fabric.

近年來，拋棄式尿布或經期衛生棉等之普及異常顯著，所要求之品質或性能正在提昇。例如，在拋棄式尿布中，1次穿著並不一定限於處理1次排泄物，需要避免對於數次排泄之不快感，除使排泄物、汗、體液等快速移行至吸收體之液體通透性(初始透水性)以外，亦特別強烈要求回滲較少(回滲性)、透水性能之耐久性(反覆透水性)。 為了應對該等要求，例如，在以下之專利文獻1中，提出有賦予有親水性處理劑之聚烯烴系不織布，上述親水性處理劑含有特定之聚醚及聚醚改性矽酮。然而，於專利文獻1中記載之聚烯烴系不織布中，雖初始透水良好，但回滲性及反覆透水性尚不充分。 [先前技術文獻] [專利文獻] [專利文獻1]日本專利特開平10-53955號公報In recent years, the popularity of disposable diapers or menstrual tampons has been remarkable, and the required quality or performance is improving. For example, in disposable diapers, one wear is not necessarily limited to handling one excrement. It is necessary to avoid the unpleasant feeling of several excretions, in addition to the rapid permeability of excreta, sweat, body fluids, etc. to the liquid permeability of the absorbent In addition to (initial water permeability), there is a strong demand for less rewet (repermeable) and durability (repeated water permeability) of water permeability. In order to meet these requirements, for example, in the following Patent Document 1, a polyolefin-based nonwoven fabric provided with a hydrophilic treatment agent is proposed, and the hydrophilic treatment agent contains a specific polyether and a polyether-modified silicone. However, in the polyolefin-based nonwoven fabric described in Patent Document 1, although initial water permeability is good, the permeability and repeated water permeability are not sufficient.

cSt者。 於本實施形態之纖維加工劑中，除成分(A)、成分(B)、成分(C)以外，只要無損所需之效果，則亦可根據所需之目的調配其他化合物。例如，可使其適當含有作為乳化劑、柔軟劑、平滑劑、抗靜電劑、消泡劑之各種界面活性劑。 纖維加工劑之附著量根據目標用途而有所不同，例如，作為衛生材料用，較佳為以作為必須成分之A成分與B成分之合計量相對於不織布附著0.05重量%至1.50重量%之方式進行塗佈。將成分A及成分B、成分C、其他化合物混合而成之纖維加工劑之附著量較佳為以除掉水等稀釋加工劑之溶劑之純分(純分附著量)計，為0.10重量%～1.50重量%之範圍，更佳為0.15重量%～1.20重量%。若未達0.05重量%則不易獲得令人滿足之透水性能，另一方面，若超過1.50重量%，則有使肌膚產生斑疹或濕疹之可能性。 於將纖維加工劑賦予至不織布時，將成分(A)、成分(B)、成分(C)之各者、或者將該等混合製成一劑者直接賦予至不織布之方法亦較為有效，但較佳為預先進行混合並利用水等溶劑進行稀釋後以纖維加工劑水溶液之形式賦予至不織布。本實施形態之纖維加工劑可藉由將成分(A)及成分(B)，根據情況，亦將成分(C)及上述其他化合物，以較佳為熔點以上之溫度混合均勻而獲得。 作為向不織布賦予纖維加工劑之方法，可採用浸漬法、噴霧法、塗佈法等已知之方法，亦可於賦予纖維加工劑後，使用熱風、熱輥等乾燥方法進行乾燥。又，亦可於賦予纖維加工劑前，視需要採用電暈放電處理、常壓電漿放電處理等處理。 為了不使伴隨不織布製造設備之高速化產生之乾燥步驟中之乾燥不足等產生，纖維加工劑水溶液之塗佈量較佳為較少。對不織布之塗佈量(重量%)於上述賦予方法之任一者中均較佳為1.0重量%～65重量%，更佳為3.0重量%～60重量%，進而較佳為5.0重量%～50重量%。若未達1.0重量%，則無法獲得均勻之塗佈，另一方面，若超過65重量%，則所需之乾燥能力變大，而設備成本增加，又，可能產生乾燥不足。再者，塗佈之纖維加工劑之濃度較佳為0.05重量%以上～100重量%。 纖維加工劑之賦予方式一般為利用塗佈進行賦予之方法。作為公知之塗佈法，可列舉接觸式塗佈機、模嘴等，由於可沿不織布寬度方向均勻地賦予纖維加工劑，故而較佳為使用利用凹版進行賦予之賦予方式。 凹版輥之柄亦可為格子型或稜錐型，較佳為纖維加工劑不易殘留於凹版之單元底之斜線型。單元體積較佳為5 cm3 /m2 ～40 cm3 /m2 。若未達5 cm3 /m2 ，則塗佈量過少，因此，難以進行纖維加工劑之均勻之塗佈。另一方面，若超過40 cm3 /m2 ，則塗佈量變得過多，因此，會產生因乾燥步驟中之乾燥不足或遷移導致產生纖維加工劑之附著斑等問題。 上述凹版輥之單元之深度較佳為10 μm～80 μm，其間隔較佳為在80目～250目之範圍內以成為上述單元體積之方式進行設計。 用以刮取凹版輥表面之液體之方式亦可為使用一般之淬火鋼板製之刮刀之刮刀方式或使用表面為橡膠製之輥之橡膠輥方式。作為刮刀方式之情形時之擠壓壓力，較佳為0.5 kg/cm～1.0 kg/cm，更佳為0.6 kg/cm～0.8 kg/cm。於橡膠輥方式之情形時，於橡膠硬度60°以上且80°以下之範圍內，擠壓壓力較佳為1.0 kg/cm以上且5.0 kg/cm以下，更佳為1.5 kg/cm以上且3.5 kg/cm以下。若於任一方式中擠壓壓力均為上述範圍內，則可沿不織布寬度方向均勻地擠壓，因此，纖維加工劑之塗佈量之偏差變少。 又，由於可應對設備之高速化、可高效地進行塗佈且容易維持不織布之厚度，故而亦較佳為利用噴霧法之賦予方式。作為噴霧法，亦可為公知之利用空氣壓縮進行之吹送法或將纖維加工劑水溶液直接壓縮後進行噴霧之方法，就可均勻地塗佈於不織布之觀點而言，較佳為轉子潤濕方式。藉由實施塗佈時之纖維加工劑水溶液之散射防止對策，而於設備之高速時亦能夠進行塗佈。所謂轉子潤濕方式，係指將纖維加工劑水溶液供給至旋轉之轉子上，使用轉子旋轉之離心力噴霧纖維加工劑水溶液之方法。於轉子潤濕方式中，以可沿塗佈的方向僅對塗佈之不織布側噴霧藉由轉子旋轉飛散之纖維加工劑水溶液之液體粒子之方式、且可沿不織布之寬度方向均勻地進行塗佈之方式限定開口部，能夠根據轉子轉數調整噴霧粒徑。 於上述轉子潤濕方式之情形時，例如，轉子之直徑選定40 mm～100 mm者，以纖維加工劑水溶液可沿塗佈之不織布之寬度方向均勻地附著之方式，設定塗佈之不織布面與轉子之中心之距離。較佳為以自相鄰之轉子噴霧之塗佈分佈範圍之2分之1重疊之方式進行設定。又，轉子較佳為沿寬度方向在60 mm～220 mm之範圍內等間隔地配置且設為2段。 均勻地進行塗佈之要點在於使噴霧粒子進入直至塗佈之不織布之內部，其噴霧粒徑較佳為10 μm～200 μm，更佳為30 μm～70 μm。對形成最佳之噴霧粒徑而言，纖維加工劑水溶液之表面張力較重要，噴霧粒徑係藉由下述式： 噴霧粒徑(μm)＝{100000×√(表面張力(N/m))}/(轉子直徑(mm)×轉子轉數(rpm)) 算出。 又，該等塗佈方法中之纖維加工劑水溶液之溫度較佳為5℃～50℃，就溶液之均勻分散、穩定性之觀點而言，更佳為12℃～40℃。纖維加工劑水溶液之黏度較佳為0.5 mPa·s～50 mPa·s，就容易更均勻地進行塗佈之觀點而言，更佳為0.8 mPa·s～20 mPa·s。若黏度超過50 mPa·s，則有纖維加工劑水溶液向不織布之浸透性變差，而難以進行均勻之塗佈之傾向。 纖維加工劑水溶液之塗佈後之乾燥可使用慣用之乾燥方式，並無特別限定，可採用利用對流傳熱、傳導傳熱、放射傳熱等之已知之方法，可使用熱風循環型、熱風貫通型、紅外線加熱器型、對不織布之兩面吹送熱風之方法、導入至加熱氣體中之方法等各種乾燥方法。 本實施形態之不織布包括熱塑性纖維，可為藉由紡黏法製造之長纖維不織布，亦可為藉由梳棉法或濕式抄紙法等製造之短纖維不織布。然而，就強度、生產性之觀點、使不織布表面結構具有特徵、對肌膚之刺激減少等之觀點而言，作為構成織物之纖維，較佳為藉由紡黏法製造之長纖維。本說明書中，所謂長纖維，係指纖維長度為55 mm以上者。又，作為熱塑性纖維之形態，不僅可使用圓形剖面者，亦可使用剖面為扁平或Y型等之異形剖面纖維、中空纖維或捲縮纖維等特殊之形態者，並無特別限定。 織物可為1層單體，亦可於藉由紡黏法(S)形成之織物之上，吹送藉由熔噴法(M)熔融紡絲之織物而進行積層。就生產性之觀點而言，積層之狀態亦可積層為SS、SSS、SSSS或以SM、SMS、SMMS、SMSMS之方式進行積層。又，亦可形成為各層不同之單位面積重量或纖維徑、纖維形態。 作為積層之織物之接合方法，亦可為使用接著劑進行接合之方法、利用低熔點纖維或複合纖維進行接著之方法、使熱熔黏合劑於織物形成中散佈而進行熔融接合之方法、利用針刺、水流等進行交絡等機械交絡或利用熱風進行之接合等方法之任一者。然而，就高速生產性之方面而言，較佳為藉由局部熱壓接進行接合。例如，可使織物於可賦予針點狀、橢圓形狀、菱形狀、矩形狀等之接合點之經加熱之壓紋/平滑輥間穿過以進行接合。就強度保持及柔軟性之方面而言，局部熱壓接中之熱壓接面積率較佳為5～40%，更佳為5～25%。又，就維持不織布之體積，可獲得作為衛生材料之頂部薄片較理想之具有緩衝性之質地之觀點而言，亦較佳為使用熱風進行接合。作為使用熱風之接合方式，只要為熱風循環型、熱風貫通型、對不織布之兩面吹送熱風之方法，則可無特別限定地加以使用。 作為構成本實施形態之熱塑性纖維之熱塑性樹脂，例如，可列舉聚乙烯、聚丙烯、共聚聚丙烯等聚烯烴系樹脂、聚對苯二甲酸乙二酯、聚對苯二甲酸丁二酯、聚萘二甲酸乙二酯、共聚聚酯等聚酯系樹脂、尼龍-6、尼龍-66、共聚尼龍等聚醯胺系樹脂、及聚乳酸、聚丁二酸丁二酯、聚丁二酸乙二酯等生物降解性樹脂，並無特別限制。就不織布之質地之觀點、及所使用之用途大多為拋棄式材料、通用、回收之方便性之觀點而言，較佳為聚烯烴系樹脂。又，纖維可為1種，亦可為並列或芯鞘等將2種以上之樹脂組合而成者。 不織布之纖維之平均纖度較佳為0.45 dtex～10.0 dtex，更佳為0.55 dtex～8.0 dtex、進而較佳為0.86 dtex～5.0 dtex。就紡絲穩定性之觀點而言，平均纖度較佳為0.45 dtex以上，另一方面，就衛生材料所使用之不織布之質地之觀點而言，較佳為10.0 dtex以下。 不織布之單位面積重量較佳為8 g/m2 ～80 g/m2 ，更佳為10 g/m2 ～40 g/m2 以下，進而較佳為10 g/m2 ～30 g/m2 。若單位面積重量為8 g/m2 以上，則作為衛生材料所使用之不織布，滿足韌度，另一方面，若為80 g/m2 以下，則有滿足衛生材料所使用之不織布之質地且外觀上不易給人很厚之印象之傾向。 賦予有本實施形態之纖維加工劑之不織布為了流暢地吸收尿或體液等，較佳為具有如下所述之特性。 成為本實施形態之不織布之透水性之指標之反覆透水性較佳為於第4次為70%以上。由於不會每次排尿時都更換尿布，故而對於頂部薄片或第二片材等所使用之不織布，對第2次、第3次反覆之排尿，亦需要流暢地使尿等體液透水。若第4次之反覆透水性之值未達70%，則於用於例如拋棄式尿布之頂部薄片或第二片材等之情形時，對第2次以後之尿無法充分地通水，因此，有成為漏尿之原因之可能性。 成為本實施形態之不織布之透水性之指標之回滲性較佳為0.5 g以下。若回滲性之值超過0.5 g，則於用於例如拋棄式尿布之表面材之情形時，排尿後，在表面材接觸肌膚時有非常濕之觸感而使用感變差，此外，有成為引起斑疹之原因之可能性。回滲性越低越好，但0.01 g以下之值為測定下限值。 成為本實施形態之不織布之透水性之指標之45度斜流長度較佳為30 mm以下，更佳為25 mm以下。若45度斜流長度超過30 mm，則於用於例如拋棄式尿布等之表面材之情形時，表面之液流變多，而容易引起漏尿。 [實施例] 以下，利用實施例、比較例對本發明進行具體說明，但本發明並不僅限定於以下之實施例。再者，各特性之評價方法如下所述，將所獲得之不織布之物性示於以下之表2。以下，將不織布製造中之流動方向稱為MD方向，將與該方向成直角之方向且寬度方向稱為CD方向。 1.平均纖度(dtex) 沿不織布之CD方向分成5等分，採取1

3.纖維加工劑水溶液之塗佈量(重量%) 將根據纖維加工劑水溶液賦予加工1小時之纖維加工劑水溶液之消耗量且藉由下述式： 纖維加工劑水溶液塗佈量(重量%)＝纖維加工劑水溶液消耗量(g)/{不織布單位面積重量(g/m2 )×寬度(m)×加工速度(m/min)×60(min)}×100 算出之值作為纖維加工劑水溶液之塗佈量(重量%)。 4.純分附著量係將根據塗佈量(重量%)且藉由下述式：

cm見方)，歷時3分鐘使吸收體中之液體之分佈固定化。繼而，將3.5 kg之砝碼暫時除去，於試驗布之上迅速地放置2片預先稱重之測定用濾紙(HOLLINGSWORTH＆VOSE.CONPANY製造之ERTMWWSSHEETS，12.5 cm見方)，再次輕輕地載置3.5 kg之砝碼。於2分鐘後稱重該測定濾紙之重量增加。將其增加之值(g)作為回滲性。 6.反覆透水性(%) 作為吸收體將10片衛生紙(Itoman股份有限公司製造之hard single 1R55m)重疊，於其上放置試驗布(20 cm×30 cm)。進而於其上放置等間隔地開有10處直徑1.5 cm之孔之不鏽鋼製之板，自位於各孔之布之上方10 mm之高度滴加生理鹽水0.05 g，經過3分鐘後，再次同樣地進行滴加。第4次之滴加後，數於10秒以內被吸收之孔之數(a)。對相同之試樣之40處進行此試驗，將{((a)/(孔10處×試樣40處)×100)}設為第4次之反覆透水性(%)。又，繼續於第5次之滴加後亦與第4次同樣地數於10秒以內被吸收之孔之數(b)，將{((b)/(孔10處×試樣40處)×100)}作為第5次之反覆透水性(%)。 7.45度斜流長度(mm) 於45度地傾斜之板上重疊10片衛生紙(Itoman股份有限公司製造之hard single 1R55m)作為吸收體，於其上放置試驗布(20 cm見方)並進行固定，自布之上方10 mm之高度滴加0.05 g之生理鹽水。讀取滴加位置至吸收結束之生理鹽水流下之距離。於試驗布內任意20處進行該測定，將其平均值作為透水45度斜流長度(mm)。 ＜不織布之製造(1)＞ 將熔體流動速率(MFR，melt

From the viewpoints of permeability and repeated water permeability, the blending ratio of the component (A) and the component (B) in the fiber processing agent is based on the mass ratio, and the component (A): component (B) = 1 is preferred: 99 to 90:10, more preferably 5:95 to 50:50. If the blending ratio of the component (A) does not reach the lower limit value, the permeability tends to decrease. If the blending ratio of the component (A) exceeds the upper limit value, the water permeability tends to decrease repeatedly. In the fiber processing agent of this embodiment, in addition to the component (A) and the component (B), a polyether-modified silicone may be further formulated as a component (C) for improving initial water permeability (45-degree oblique flow length).

From the viewpoints of permeability, repeated water permeability, and 45-degree oblique flow length, those having an HLB of 5 to 15 are suitable, and suitable for use. Those with viscosity of 50 ～ 10000 cSt. In the fiber processing agent of the present embodiment, in addition to the component (A), the component (B), and the component (C), as long as the desired effect is not impaired, other compounds can be formulated according to the desired purpose. For example, various surfactants can be appropriately contained as emulsifiers, softeners, smoothing agents, antistatic agents, and antifoaming agents. The adhesion amount of the fiber processing agent varies depending on the intended use. For example, as a sanitary material, it is preferable that the total amount of the A component and the B component as an essential component is 0.05% to 1.50% by weight relative to the non-woven fabric. Perform coating. The adhesion amount of the fiber processing agent obtained by mixing the component A, the component B, the component C, and other compounds is preferably 0.10% by weight based on the pure content (pure content adhesion amount) of the solvent in which the diluting processing agent such as water is removed The range is from 1.50% by weight, more preferably from 0.15% by weight to 1.20% by weight. If it is less than 0.05% by weight, it is difficult to obtain satisfactory water permeability. On the other hand, if it exceeds 1.50% by weight, skin rash or eczema may occur. In the case of imparting a fiber processing agent to a nonwoven fabric, it is also effective to directly apply each of the component (A), the component (B), and the component (C) to the nonwoven fabric, but a method of directly imparting it to the nonwoven fabric, but It is preferable to mix and dilute with a solvent, such as water, and to give it as a fiber processing agent aqueous solution to a nonwoven fabric in advance. The fiber processing agent of this embodiment can be obtained by mixing the component (A) and the component (B) and, depending on the case, the component (C) and the other compounds mentioned above at a temperature of preferably a melting point or more. As a method for imparting a fiber processing agent to the non-woven fabric, a known method such as a dipping method, a spray method, or a coating method may be adopted. After the fiber processing agent is applied, drying may be performed using a drying method such as hot air or a hot roll. In addition, before applying the fiber processing agent, if necessary, a treatment such as a corona discharge treatment or an ordinary piezoelectric slurry discharge treatment may be applied. The application amount of the fiber processing agent aqueous solution is preferably small so as not to cause insufficient drying in the drying step and the like caused by the high-speed production of the nonwoven fabric manufacturing equipment. The coating amount (% by weight) on the non-woven fabric is preferably 1.0% to 65% by weight, more preferably 3.0% to 60% by weight, and still more preferably 5.0% by weight to any one of the above-mentioned application methods. 50% by weight. If it is less than 1.0% by weight, uniform coating cannot be obtained. On the other hand, if it exceeds 65% by weight, the required drying capacity becomes large, the equipment cost increases, and insufficient drying may occur. The concentration of the applied fiber processing agent is preferably from 0.05% by weight to 100% by weight. The application method of a fiber processing agent is generally a method of application by coating. Examples of known coating methods include a contact coater, a die, and the like. Since the fiber processing agent can be uniformly applied in the width direction of the nonwoven fabric, it is preferable to use a method of applying using a gravure. The handle of the gravure roll may also be a lattice type or a pyramidal shape, and it is preferably an oblique line type in which the fiber processing agent does not easily remain on the bottom of the unit of the gravure. Unit volume is preferably 5 cm 3 / m 2 ～ 40 cm 3 / m 2 . Up to 5 cm 3 / m 2 If the coating amount is too small, it is difficult to uniformly apply the fiber processing agent. On the other hand, if it exceeds 40 cm 3 / m 2 , The coating amount becomes excessive, and therefore, problems such as adhesion spots of the fiber processing agent due to insufficient drying or migration in the drying step may occur. The depth of the unit of the gravure roll is preferably 10 μm to 80 μm, and the interval is preferably designed in the range of 80 mesh to 250 mesh so as to become the above-mentioned cell volume. The method for scraping the liquid on the surface of the gravure roller may also be a doctor blade method using a general blade made of hardened steel plate or a rubber roller method using a roller made of rubber. The squeezing pressure in the case of the doctor blade method is preferably 0.5 kg / cm to 1.0 kg / cm, and more preferably 0.6 kg / cm to 0.8 kg / cm. In the case of the rubber roller method, the compression pressure is preferably 1.0 kg / cm or more and 5.0 kg / cm or less, more preferably 1.5 kg / cm or more and 3.5 in a rubber hardness range of 60 ° to 80 °. kg / cm or less. If the extrusion pressure is within the above range in either method, the nonwoven fabric can be uniformly squeezed in the width direction of the nonwoven fabric. Therefore, the variation in the application amount of the fiber processing agent is reduced. In addition, since it can cope with the increase in the speed of the equipment, can efficiently coat, and easily maintain the thickness of the non-woven fabric, it is also preferable to use a spraying method. As the spray method, a known blowing method using air compression or a method of spraying a fiber processing agent aqueous solution directly before spraying may be used. From the viewpoint of being uniformly applied to a non-woven fabric, a rotor wetting method is preferred. . By implementing measures to prevent scattering of the fiber processing agent aqueous solution at the time of coating, coating can also be performed at high speed of the equipment. The so-called rotor wetting method refers to a method of supplying a fiber processing agent aqueous solution to a rotating rotor and spraying the fiber processing agent aqueous solution using the centrifugal force of the rotor rotation. In the rotor wetting method, only the coated nonwoven fabric side can be sprayed with the liquid particles of the fiber processing agent aqueous solution scattered by the rotor's rotation in the coating direction, and the coating can be uniformly applied in the width direction of the nonwoven fabric. This method limits the opening portion, and the spray particle size can be adjusted according to the number of revolutions of the rotor. In the case of the above-mentioned rotor wetting method, for example, if the diameter of the rotor is selected from 40 mm to 100 mm, the coated nonwoven fabric surface and the coated nonwoven fabric are set in such a manner that the fiber processing agent aqueous solution can adhere uniformly along the width direction of the coated nonwoven fabric. The distance from the center of the rotor. It is preferable to set it so that 1/2 of the coating distribution range sprayed from the adjacent rotor may overlap. The rotor is preferably arranged at equal intervals in the range of 60 mm to 220 mm in the width direction and is provided in two stages. The main point of uniform coating is that the spray particles enter the interior of the coated nonwoven fabric. The spray particle diameter is preferably 10 μm to 200 μm, and more preferably 30 μm to 70 μm. For forming the optimal spray particle diameter, the surface tension of the fiber processing agent aqueous solution is more important. The spray particle diameter is based on the following formula: Spray particle diameter (μm) = {100000 × √ (surface tension (N / m)) )} / (Rotor diameter (mm) x rotor revolutions (rpm)). The temperature of the fiber processing agent aqueous solution in these coating methods is preferably 5 ° C to 50 ° C, and from the viewpoint of uniform dispersion and stability of the solution, it is more preferably 12 ° C to 40 ° C. The viscosity of the fiber processing agent aqueous solution is preferably 0.5 mPa · s to 50 mPa · s, and from the viewpoint of easy and uniform application, it is more preferably 0.8 mPa · s to 20 mPa · s. When the viscosity exceeds 50 mPa · s, the permeability of the aqueous fiber processing agent solution to the nonwoven fabric is deteriorated, and it is difficult to perform uniform coating. The conventional drying method can be used for the drying of the fiber processing agent aqueous solution after coating, and known methods such as convective heat transfer, conductive heat transfer, and radiant heat transfer can be used. Hot air circulation type and hot air penetration can be used. Various types of drying methods, such as the method of blowing hot air on both sides of the non-woven fabric, the method of introducing an infrared heater, the method of introducing hot air to both sides of the non-woven fabric. The non-woven fabric of this embodiment includes thermoplastic fibers, and may be a long-fiber non-woven fabric manufactured by a spunbond method, or a short-fiber non-woven fabric manufactured by a carding method or a wet papermaking method. However, from the viewpoints of strength and productivity, characteristics of the surface structure of the non-woven fabric, and reduction of irritation to the skin, long fibers produced by a spunbond method are preferred as the fibers constituting the fabric.
