It should be noted that although polyester is used as the main component of the melt-blown fiber in the following description, the main component of the melt-blown fiber disclosed in the present disclosure may also include materials such as polypropylene or nylon.

首先，進行步驟S10，將87重量份至91重量份的聚酯、5重量份至7重量份的撥水劑以及3重量份至6重量份的流促劑均勻混合，並進行混練製程，以形成混合物。以上述試劑混合而成的混合物在溫度為270℃時具有介於530g/10min至1540g/10min間的熔融指數(Melt Index，MI)，使其於後續的熔噴製程期間可具有良好的流動性，從而使透氣防水不織布110具有良好的耐水壓性。如此一來，可使透氣防水織物100具有良好的防水性。在一些實施方式中，混練製程的溫度可介於235℃至245℃間。 First, perform step S10, uniformly mix 87 to 91 parts by weight of polyester, 5 to 7 parts by weight of water repellent, and 3 to 6 parts by weight of flow accelerator, and perform a kneading process to A mixture is formed. The mixture formed by mixing the above reagents has a melt index (Melt Index, MI) between 530g/10min and 1540g/10min at a temperature of 270°C, so that it can have good fluidity during the subsequent melt blown process , so that the breathable waterproof non-woven fabric 110 has good water pressure resistance. In this way, the breathable waterproof fabric 100 can have good waterproof performance. In some embodiments, the temperature of the kneading process may be between 235°C and 245°C.

聚酯用以作為透氣防水不織布110中的熔噴纖維的主要原料，也就是說，熔噴纖維包括聚酯。在一些實施方式中，聚酯在溫度為270℃時具有可介於350g/10min至1310g/10min間的熔融指數，以於後續的熔噴製程期間提供混合物一定的流動性。詳細而言，不同種類的聚酯可具有不同範圍的熔融指數。舉例而言，第一種類的聚酯在溫度為270℃時可具有介於350g/10min至450g/10min間的熔融指數，而第二種類的聚酯在溫度為270℃時可具有介於1210g/10min至1310g/10min間的熔融指數。在一些實施方式中，聚酯可例如是聚對苯二甲酸乙二酯(PET)、聚對苯二甲酸丙二酯(PPT)或聚對苯二甲酸丁二酯(PBT)。 Polyester is used as the main raw material of the melt-blown fibers in the breathable and waterproof non-woven fabric 110, that is, the melt-blown fibers include polyester. In some embodiments, the polyester has a melt index ranging from 350 g/10 min to 1310 g/10 min at a temperature of 270° C., so as to provide the mixture with certain fluidity during the subsequent melt blowing process. In detail, different kinds of polyesters may have different ranges of melt indices. For example, the first type of polyester may have a melt index between 350 g/10 min and 450 g/10 min at a temperature of 270° C., while the second type of polyester may have a melt index between 1210 g/10 min at a temperature of 270° C. Melt index between /10min and 1310g/10min. In some embodiments, the polyester can be, for example, polyethylene terephthalate (PET), polytrimethylene terephthalate (PPT), or polybutylene terephthalate (PBT).

撥水劑用以提供透氣防水不織布110良好的撥水性。在一些實施方式中，撥水劑可具有介於350nm至450nm間的粒徑(D90)，以於混練製程期間均勻分散於混合物中，從而提供透氣防水不織布110良好的撥水性，並提供使用者穿戴舒適性。詳細而言，若撥水劑的粒徑大於450nm，其可能因無法均勻分散於混合物中而難以提供良好的撥水性，並可能使透氣防水不織布110具有顯著的顆粒感，無法提供穿戴舒適性。在一些實施方式中，撥水劑可包括二氧化矽或二氧化矽氣凝膠，且在微觀尺度下，二氧化矽或二氧化矽氣凝膠的形狀可例如是球狀，從而具有低表面能，以提供良好的撥水性。在一些實施方式中，二氧化矽或二氧化矽氣凝膠的比表面積可介於600m 2/g至800m 2/g間，以有利於強化其低密度、高孔隙率以及高疏水性等特性，從而提供透氣防水不織布110良好的撥水性。 The water repellent is used to provide good water repellency of the breathable waterproof non-woven fabric 110 . In some embodiments, the water-repellent agent can have a particle size (D90) between 350nm and 450nm, so that it can be uniformly dispersed in the mixture during the kneading process, so as to provide good water-repellency for the breathable waterproof non-woven fabric 110 and provide users with Wearing comfort. In detail, if the particle size of the water-repellent agent is greater than 450 nm, it may be difficult to provide good water-repellency because it cannot be uniformly dispersed in the mixture, and may make the breathable waterproof non-woven fabric 110 have a significant grainy feel, which cannot provide wearing comfort. In some embodiments, the water-repellent agent may include silica or silica aerogel, and on a microscopic scale, the shape of silica or silica aerogel may, for example, be spherical, thereby having a low surface area. Can, in order to provide good water repellency. In some embodiments, the specific surface area of silica or silica airgel can be between 600m 2 /g and 800m 2 /g, which is beneficial to enhance its characteristics of low density, high porosity and high hydrophobicity , so as to provide the breathable waterproof non-woven fabric 110 with good water repellency.

流促劑用以提供透氣防水不織布110良好的耐水壓性，以使透氣防水織物100具有良好的防水性。詳細而言，流促劑可使前述混合物相較於聚酯具有較低的熔融指數，亦即，混合物相較於聚酯可具有較佳的流動性，使得混合物於後續的熔噴製程期間所形成的熔噴纖維可具有低的纖維細度，從而使得透氣防水不織布110具有高的纖維分佈均勻度以及小的孔徑，以提供透氣防水不織布110良好的耐水壓性。如前所述，混合物在溫度為270℃時具有介於530g/10min至1540g/10min間的熔融指數。更詳細而言，當使用前述第一種類的聚酯形成混合物時，混合物在溫度為270℃時可具有介於530g/10min至630g/10min間的熔融指數，而當使用前述第二種類的聚酯形成混合物時，混合物在溫度為270℃時可具有介於1440g/10min至1540g/10min間的熔融指數。The flow enhancer is used to provide the breathable waterproof non-woven fabric 110 with good water pressure resistance, so that the breathable waterproof fabric 100 has good waterproofness. In detail, the flow enhancer can make the aforementioned mixture have a lower melt index than polyester, that is, the mixture can have better fluidity than polyester, so that the mixture can be melted during the subsequent melt-blown process. The formed meltblown fibers may have low fiber fineness, so that the breathable waterproof nonwoven fabric 110 has high fiber distribution uniformity and small pore size, so as to provide the breathable waterproof nonwoven fabric 110 with good water pressure resistance. As previously stated, the mixture has a melt index between 530 g/10 min and 1540 g/10 min at a temperature of 270°C. More specifically, when the aforementioned first type of polyester is used to form a mixture, the mixture may have a melt index between 530 g/10 min and 630 g/10 min at a temperature of 270° C., and when the aforementioned second type of polyester is used Where the esters form a mixture, the mixture may have a melt index between 1440 g/10 min and 1540 g/10 min at a temperature of 270°C.

在一些實施方式中，流促劑可包括0.1至6.0重量份的滑劑以及0.1至6.0重量份的多元醇。滑劑以及多元醇皆可使混合物具有良好的流動性，而多元醇更可提升滑劑與聚酯間的相容性。在一些實施方式中，多元醇可包括乙二醇、丙二醇、丁二醇、聚乙二醇或其組合。在一些實施方式中，流促劑在溫度為250℃以上時容易揮發，而在溫度為250℃以下時可穩定地存在於混合物中。基於此特性，流促劑在混練製程期間(溫度小於250℃)可穩定地存在於混合物中，以使混合物具有良好的流動性，而其在後續的熔噴製程期間(溫度大於等於250℃)則會揮發，以避免殘留於透氣防水不織布110中。In some embodiments, the flow enhancer may include 0.1 to 6.0 parts by weight of a slip agent and 0.1 to 6.0 parts by weight of a polyol. Both the lubricant and the polyol can make the mixture have good fluidity, and the polyol can improve the compatibility between the lubricant and the polyester. In some embodiments, the polyol can include ethylene glycol, propylene glycol, butylene glycol, polyethylene glycol, or combinations thereof. In some embodiments, the flow enhancer is easy to volatilize when the temperature is above 250°C, but can stably exist in the mixture when the temperature is below 250°C. Based on this characteristic, the flow enhancer can be stably present in the mixture during the kneading process (temperature less than 250°C), so that the mixture has good fluidity, and it can be used during the subsequent melt-blown process (temperature greater than or equal to 250°C) It will be volatilized to avoid remaining in the breathable waterproof non-woven fabric 110.

接著，進行步驟S20及S30，對前述混合物進行熔噴製程以形成熔噴纖維，並承接多條熔噴纖維。在熔噴製程期間，混合物中的流促劑在熔噴製程期間會揮發，而剩餘的聚酯及撥水劑可藉由熔噴製程而形成熔噴纖維。在一些實施方式中，熔噴製程的溫度可介於250℃至275℃間，以確保混合物在熔噴製程期間具有足夠的流動性，並確保流促劑完全地揮發。請先參閱第3圖，其繪示第1圖的透氣防水不織布110中的熔噴纖維F的立體示意圖。熔噴纖維F具有纖維本體B及撥水劑W，且撥水劑W配置於纖維本體B上。在一些實施方式中，撥水劑W可附著於纖維本體B的表面。在較佳的實施方式中，撥水劑W可僅附著於纖維本體B的表面，且免於滲入纖維本體B中。需特別說明的是，本文中的「免於滲入纖維本體B中」是指「內嵌於纖維本體B的表面，並部分地由纖維本體B的表面裸露出來」(如第3圖所示)。Next, steps S20 and S30 are performed, performing a melt-blown process on the aforementioned mixture to form melt-blown fibers, and accepting a plurality of melt-blown fibers. During the melt-blowing process, the flow enhancer in the mixture will volatilize during the melt-blown process, and the remaining polyester and water repellant can form melt-blown fibers through the melt-blown process. In some embodiments, the temperature of the melt-blowing process may be between 250° C. and 275° C. to ensure sufficient fluidity of the mixture during the melt-blown process and to ensure that the flow enhancer is completely volatilized. Please refer to FIG. 3 first, which shows a perspective view of the melt-blown fiber F in the breathable and waterproof non-woven fabric 110 of FIG. 1 . The melt-blown fiber F has a fiber body B and a water-repellent agent W, and the water-repellent agent W is disposed on the fiber body B. In some embodiments, the water repellant W can be attached to the surface of the fiber body B. In a preferred embodiment, the water-repellent agent W can only adhere to the surface of the fiber body B and avoid penetrating into the fiber body B. It should be noted that "free from penetration into the fiber body B" in this article means "embedded in the surface of the fiber body B and partially exposed from the surface of the fiber body B" (as shown in Figure 3) .

隨後，進行步驟S40，對承接後的多條熔噴纖維F進行壓光製程，以形成透氣防水不織布110。在經壓光製程所形成的透氣防水不織布110具有小的孔徑，從而提供透氣防水不織布110良好的耐水壓性，使得透氣防水織物100可具有良好的防水性。舉例而言，本揭露的透氣防水不織布110可承受介於6000mmH 2O至8000mmH 2O的水壓。 Subsequently, step S40 is performed to perform a calendering process on the received plurality of melt-blown fibers F to form a breathable and waterproof non-woven fabric 110 . The breathable and waterproof non-woven fabric 110 formed through the calendering process has a small pore size, thereby providing the breathable and waterproof non-woven fabric 110 with good water pressure resistance, so that the breathable and waterproof fabric 100 can have good waterproofness. For example, the breathable waterproof non-woven fabric 110 of the present disclosure can withstand a water pressure between 6000 mmH 2 O and 8000 mmH 2 O.

在完成上述步驟S10至S40後，便可形成透氣防水不織布110。整體而言，透氣防水不織布110是由多條熔噴纖維F所構成，其中每一條熔噴纖維F具有纖維本體B及撥水劑W，且撥水劑W配置於纖維本體B的表面。由於撥水劑W是以合適的尺寸配置於纖維本體B的表面，因此可良好地發揮其撥水性並使得透氣防水不織布110提供良好的穿戴舒適性。另外，由於熔噴纖維F具有低的纖維細度，因此可使透氣防水不織布110具有高的纖維分佈均勻度。此外，由於透氣防水不織布110具有小的孔徑，因此可提供透氣防水不織布110良好的耐水壓性，使得透氣防水織物100具有良好的防水性。After the above steps S10 to S40 are completed, the breathable waterproof non-woven fabric 110 can be formed. Overall, the breathable waterproof non-woven fabric 110 is composed of a plurality of melt-blown fibers F, wherein each melt-blown fiber F has a fiber body B and a water-repellent agent W, and the water-repellent agent W is disposed on the surface of the fiber body B. Since the water-repellent agent W is disposed on the surface of the fiber body B with an appropriate size, it can exert its water-repellent property well and make the breathable and waterproof non-woven fabric 110 provide good wearing comfort. In addition, since the melt-blown fibers F have low fiber fineness, the breathable and waterproof non-woven fabric 110 can have high fiber distribution uniformity. In addition, since the breathable and waterproof non-woven fabric 110 has a small pore size, it can provide good water pressure resistance of the breathable and waterproof non-woven fabric 110 , so that the breathable and waterproof fabric 100 has good waterproof performance.

第4圖繪示第1圖的透氣防水織物100中的第一黏著層120的配置示意圖。請參閱第1圖以及第4圖，第一黏著層120是配置於透氣防水不織布110的第一表面111，以將第一基布130固定於透氣防水不織布110的第一表面111。在一些實施方式中，第一黏著層120可例如是濕氣反應型熱熔膠，以具有強的黏合力以及高的固化速度。在一些實施方式中，第一黏著層120可在溫度為110℃至130℃間時以點膠的方式形成於透氣防水不織布110的第一表面111，且第一黏著層120在溫度為90℃時的黏度可介於8000cP至9000cP間。藉此，可輕易地將第一黏著層120轉移至透氣防水不織布110上，並可良好地控制第一黏著層120的成型位置。詳細而言，若第一黏著層120在溫度為90℃時的黏度小於8000cP，可能因其流動性過高而不易控制第一黏著層120的成型位置；若第一黏著層120在溫度為90℃時的黏度大於9000cP，可能因其過於黏稠而不易轉移至透氣防水不織布110上。FIG. 4 shows a schematic diagram of the configuration of the first adhesive layer 120 in the breathable waterproof fabric 100 of FIG. 1 . Please refer to FIG. 1 and FIG. 4 , the first adhesive layer 120 is disposed on the first surface 111 of the breathable and waterproof non-woven fabric 110 to fix the first base fabric 130 on the first surface 111 of the breathable and waterproof non-woven fabric 110 . In some embodiments, the first adhesive layer 120 can be, for example, a moisture-responsive hot-melt adhesive, so as to have strong adhesive force and high curing speed. In some embodiments, the first adhesive layer 120 can be formed on the first surface 111 of the breathable waterproof non-woven fabric 110 by dispensing glue at a temperature between 110°C and 130°C, and the first adhesive layer 120 can be formed at a temperature of 90°C. When the viscosity can be between 8000cP to 9000cP. Thereby, the first adhesive layer 120 can be easily transferred to the breathable waterproof non-woven fabric 110 , and the forming position of the first adhesive layer 120 can be well controlled. Specifically, if the viscosity of the first adhesive layer 120 is less than 8000 cP at a temperature of 90° C., it may be difficult to control the molding position of the first adhesive layer 120 because of its high fluidity; The viscosity at °C is greater than 9000 cP, which may be difficult to transfer to the breathable and waterproof non-woven fabric 110 because it is too viscous.

第一黏著層120是配置於透氣防水不織布110的第一表面111，且具有多個黏著點122。在一些實施方式中，黏著點122可例如是間隔地配置於透氣防水不織布110的第一表面111，以使透氣防水織物100具有良好的透氣性。在較佳的實施方式中，黏著點122可例如是等距地配置於透氣防水不織布110的第一表面111，以使透氣防水織物100具有良好的布料平整性及均勻的透氣性。在一些實施方式中，黏著點122的俯視形狀(即由第4圖的視角觀察所呈現的形狀)可例如是矩形、菱形、圓形、橢圓形、三角形、梯形或任何合適的形狀。The first adhesive layer 120 is disposed on the first surface 111 of the breathable waterproof non-woven fabric 110 and has a plurality of adhesive points 122 . In some embodiments, the adhesive points 122 may be arranged at intervals on the first surface 111 of the breathable waterproof non-woven fabric 110 , so that the breathable waterproof fabric 100 has good air permeability. In a preferred embodiment, the adhesive points 122 can be equidistantly arranged on the first surface 111 of the breathable waterproof non-woven fabric 110 , so that the breathable waterproof fabric 100 has good cloth flatness and uniform air permeability. In some embodiments, the top view shape of the adhesive point 122 (ie, the shape viewed from the perspective of FIG. 4 ) can be, for example, a rectangle, a rhombus, a circle, an ellipse, a triangle, a trapezoid, or any suitable shape.

另一方面，黏著點122的分布密度及尺寸亦可影響透氣防水織物100的透氣性。在一些實施方式中，黏著點122的分布密度可介於8個/mm 2至10個/mm 2間，且若以圓形的黏著點122為例，每一個黏著點122的直徑D可介於90μm至110μm間。詳細而言，若黏著點122的分布密度大於10個/mm 2及/或每一個黏著點122的直徑D大於110μm，可能導致透氣防水織物100的透氣性不足；若黏著點122的分布密度小於5個/mm 2及/或每一個黏著點122的直徑D小於90μm，可能導致第一黏著層120的黏著力不足，從而影響透氣防水織物100的穩固性。 On the other hand, the distribution density and size of the adhesive points 122 can also affect the air permeability of the breathable waterproof fabric 100 . In some embodiments, the distribution density of the adhesion points 122 can be between 8 pieces/mm 2 and 10 pieces/mm 2 , and if circular adhesion points 122 are taken as an example, the diameter D of each adhesion point 122 can be between Between 90μm and 110μm. In detail, if the distribution density of the adhesion points 122 is greater than 10/mm and /or the diameter D of each adhesion point 122 is greater than 110 μm, the air permeability of the breathable waterproof fabric 100 may be insufficient; if the distribution density of the adhesion points 122 is less than 5/mm 2 and/or the diameter D of each adhesive point 122 is less than 90 μm, which may result in insufficient adhesive force of the first adhesive layer 120 , thereby affecting the stability of the breathable waterproof fabric 100 .

Thereby, the second adhesive layer 140 can be easily transferred to the breathable waterproof non-woven fabric 110 , and the molding thickness of the second adhesive layer 140 can be well controlled. Specifically, if the viscosity of the second adhesive layer 140 is less than 8000 cP at a temperature of 90° C., it may be difficult to control the molding thickness of the first adhesive layer 120 because of its high fluidity; The viscosity at °C is greater than 9000 cP, which may be difficult to transfer to the breathable and waterproof non-woven fabric 110 because it is too viscous.

在一些實施方式中，透氣防水織物100可更包括第二基布150，其藉由第二黏著層140配置於透氣防水不織布110的第二表面113。換句話說，第二基布150及第一基布130分別藉由第二黏著層140及第一黏著層120而配置在透氣防水不織布110的相對兩表面。在一些實施方式中，基於第二黏著層140是以整面的型態配置，第二基布150可例如是緻密性低的梭織布，當透氣防水織物100用以做為穿戴服飾時，第二基布150可配置以做為服飾的內層布料。In some embodiments, the breathable waterproof fabric 100 may further include a second base fabric 150 disposed on the second surface 113 of the breathable waterproof non-woven fabric 110 through the second adhesive layer 140 .
