Description
本發明是有關於一種彈性不織布基材的製造方法，且特別是有關於一種可提高彈性不織布與支撐材的結合力之彈性不織布基材的製造方法。 The present invention relates to a method for producing an elastic nonwoven substrate, and more particularly to a method for producing an elastic nonwoven substrate capable of improving the bonding strength between the elastic nonwoven fabric and the support member.
在傳統的紡織工業中，針對於穿著時需彈性貼合人體的衣著(例如紙尿褲或運動服飾等)採用鬆緊帶，但其具有較不輕薄以及製程繁瑣的缺點。隨著紡織產業的進步，開發出更輕薄的彈性不織布裡襯，其具有加工製程更加快速的優點，可應用於紙尿褲、擦拭布、醫療衛材、運動服飾及羽絨服等用途。 In the conventional textile industry, an elastic band is used for clothing that is elastically fitted to the human body when worn (for example, diapers or sportswear, etc.), but it has the disadvantages of being less lightweight and cumbersome in process. With the advancement of the textile industry, the development of a thinner and more elastic non-woven bristle lining has the advantages of faster processing, and can be applied to diapers, wiping cloths, medical materials, sportswear and down jackets.
在對彈性不織布裡襯進行後加工點膠製程時，彈性不織布的伸長率太大，會造成加工困難，因此，需要一層伸長率較低的支撐材，以便於後加工。此外，在使用彈性不織布裡襯時，通常會將裡襯布堆疊起來，利用刀模裁切成所需大小。然而，單層彈性不織布材料堆疊裁切後容易彼此黏結，因此，需要支撐材輔助，以幫助裡襯布之間剝離。 In the post-processing of the elastic non-woven bristle lining, the elongation of the elastic non-woven fabric is too large, which causes processing difficulties. Therefore, a support material having a low elongation is required for post-processing. In addition, when elastic non-woven linings are used, the linings are usually stacked and cut to the desired size using a die. However, the single layer of elastic non-woven material material is easily bonded to each other after being cut, and therefore, support material assistance is required to help peel off the inner lining cloth.
在習知技術中，大多採用熱熔製程，不織布由熱塑性高分子材料製成，利用升溫並施加壓力等加工方式(如熱壓、熱風黏合等)，可使熱塑性高分子材料熔融且相互黏結，因此具有結合力。然而，熔融後不織布的手感改變，且熔融面積越大，手感越硬。此外，熱熔製程更具有彈性變差的缺點，由於不織布熔融部分類似塑膠片材，未熔融部分為纖維，兩種形態的拉伸性質差異大，若使用熱壓方法結合，則會影響彈性。 In the conventional technology, a hot melt process is mostly used, and the non-woven fabric is made of a thermoplastic polymer material, and the thermoplastic polymer material is melted and bonded to each other by a processing method such as heat pressing and pressure application (such as hot pressing or hot air bonding). Therefore, it has a binding force. However, the feel of the non-woven fabric after melting changes, and the larger the melting area, the harder the hand feel. In addition, the hot-melt process has the disadvantage of poor elasticity. Since the melted portion of the nonwoven fabric is similar to the plastic sheet, the unmelted portion is the fiber, and the tensile properties of the two forms are greatly different. If the combination is performed by the hot pressing method, the elasticity is affected.
基於上述，發展出一種能夠提高彈性不織布與支撐材之間的結合力的方法，以便於後加工及使用，且不影響彈性及手感，為目前所需研究的重要課題。 Based on the above, a method for improving the bonding force between the elastic nonwoven fabric and the support material has been developed to facilitate post-processing and use without affecting elasticity and hand feeling, and is an important subject for current research.

Tangled or stitched with a thread. Next, the elastic nonwoven substrate is subjected to a dispensing process. Hereinafter, each detail in the manufacturing method of the elastic nonwoven fabric substrate of this invention is demonstrated in detail.
本發明之彈性不織布基材的製造方法中，對熱塑性彈性體進行熔噴製程、紡黏製程或由熱塑性彈性體的短纖維或長纖維形成彈性不織布，以形成具有紋路的彈性不織布，紋路有助於改善CD方向上的彈性。更詳細而言，熱塑性彈性體可包括聚酯、聚醯胺或聚烯烴熱塑性高分子材料。 In the method for producing an elastic nonwoven substrate of the present invention, the thermoplastic elastomer is subjected to a melt-blown process, a spunbond process, or an elastic nonwoven fabric formed of short fibers or long fibers of a thermoplastic elastomer to form an elastic nonwoven fabric having a texture, and the texture is helpful. Improve the elasticity in the CD direction. In more detail, the thermoplastic elastomer may comprise a polyester, polyamide or polyolefin thermoplastic polymer material.
在本實施例中，熔噴製程的溫度可分為入料溫度、流道溫度以及模頭溫度，其中入料溫度可包括三段溫度，溫度範圍可為150℃~250℃，流道溫度可包括七段溫度，溫度範圍可為150℃~300℃，模頭溫度可包括三段溫度，溫度範圍可為250℃~300℃，熱風溫度可為100℃~200℃，風量為10m3。 In this embodiment, the temperature of the melt-blown process can be divided into a feed temperature, a flow channel temperature, and a die temperature, wherein the feed temperature can include three-stage temperature, the temperature range can be 150 ° C to 250 ° C, and the flow channel temperature can be Including seven sections of temperature, the temperature range can be 150 ° C ~ 300 ° C, the die temperature can include three sections of temperature, the temperature range can be 250 ° C ~ 300 ° C, the hot air temperature can be 100 ° C ~ 200 ° C, the air volume is 10 m 3 .
本發明之彈性不織布基材的製造方法中，將彈性不織布與支撐材貼合，以組成彈性不織布基材，並於彈性不織布與支撐材之間進行介面處理。更詳細而言，介面處理包括靜電駐極、感壓膠、超音波黏合、纖維物理性糾結纏繞或線縫合的介面處理方式，以提高彈性不織布與支撐材之間的結合力。支撐材包括可紡黏不織布或其他具有固定彈性不織布尺寸效果之支撐材，其中紡 黏不織布的材料可包括聚丙烯、聚酯或聚醯胺。 In the method for producing an elastic nonwoven fabric substrate of the present invention, the elastic nonwoven fabric is bonded to the support member to constitute an elastic nonwoven fabric substrate, and the interface between the elastic nonwoven fabric and the support member is performed.

The frequency vibration causes the molecules in the material to undergo intense friction to produce local high temperature. When the temperature is higher than the melting point of the material, the material is melted, and after the molten material is cooled, the bonding is re-solidified to achieve the welding effect.
本發明之彈性不織布基材的製造方法中，對彈性不織布基材進行後加工點膠製程。由於本發明的彈性不織布基材包括支撐材，且彈性不織布與支撐材之間藉由靜電駐極、感壓膠、超音波黏合、纖維物理性糾結纏繞或以線縫合的介面處理方式提升結合力，因此，有利於後加工點膠製程的進行。 In the method for producing an elastic nonwoven substrate of the present invention, the elastic nonwoven substrate is subjected to a post-processing dispensing process. Since the elastic nonwoven substrate of the present invention comprises a support material, and the elastic non-woven fabric and the support material are improved by the electrostatic electret, the pressure sensitive adhesive, the ultrasonic bonding, the fiber physical entanglement winding or the wire stitching interface treatment method. Therefore, it is advantageous for the post-processing dispensing process.
在本實施例中，提出兩種不同的方法進行點膠製程。第一，點膠製程可包括將高分子樹脂膠體塗佈於彈性不織布上。第二，點膠製程可包括將高分子樹脂膠體塗佈於彈性不織布上，再加上高分子材料粉末。更詳細而言，高分子樹脂膠體可包括聚酯、聚醯胺、聚氨酯、聚乙烯、甲基丙烯酸甲酯或其兩者的共聚物或共混物，高分子材料粉末可包括聚酯、聚醯胺、聚氨酯、聚乙烯、 甲基丙烯酸甲酯或其兩者的共聚物或共混物。 In this embodiment, two different methods are proposed for the dispensing process. First, the dispensing process can include applying a polymer resin colloid to the elastic nonwoven fabric. Second, the dispensing process may include applying a polymer resin colloid to the elastic nonwoven fabric, and adding the polymer material powder. In more detail, the polymer resin colloid may include a copolymer or a blend of polyester, polyamine, polyurethane, polyethylene, methyl methacrylate or both, and the polymer material powder may include polyester, poly A copolymer or blend of guanamine, polyurethane, polyethylene, methyl methacrylate or both.
依據上文所述之彈性不織布基材的製造方法，即可完成本發明的彈性不織布基材。藉由本發明的製造方法所製成的彈性不織布基材可在裁切後與織物貼合(加上溫度與壓力)。由於本發明的彈性不織布基材包括支撐材，且彈性不織布與支撐材之間藉由靜電駐極、感壓膠、超音波黏合、纖維物理性糾結纏繞或以線縫合的介面處理方式提升結合力，因此，在裁切時有助於裡襯布之間剝離，提升使用上的便利性，且不影響彈性及手感。並且，本發明的彈性不織布基材與織物貼合後，需將支撐材移除，若使用習知的熱熔方式，則難以達成此應用目的。 The elastic nonwoven substrate of the present invention can be completed in accordance with the above-described method for producing an elastic nonwoven substrate. The elastic nonwoven substrate produced by the manufacturing method of the present invention can be bonded to the fabric after cutting (plus temperature and pressure). Since the elastic nonwoven substrate of the present invention comprises a support material, and the elastic non-woven fabric and the support material are improved by the electrostatic electret, the pressure sensitive adhesive, the ultrasonic bonding, the fiber physical entanglement winding or the wire stitching interface treatment method. Therefore, it is helpful to peel off the lining cloth during cutting, and the convenience in use is improved without affecting the elasticity and the hand feeling. Further, after the elastic nonwoven fabric substrate of the present invention is bonded to the fabric, the support material needs to be removed, and if a conventional hot melt method is used, it is difficult to achieve the purpose of the application.
在所製成的彈性不織布基材之性質方面，纖維直徑小於10μm，手感柔軟，依據ISO 105-X18：2007進行酚黃測試的結果為4/5，依據GB/T 7573-2009測得的pH值為5.6。 In terms of the properties of the elastic nonwoven substrate produced, the fiber diameter is less than 10 μm, and the hand feel is soft. The result of the phenol yellow test according to ISO 105-X18:2007 is 4/5, and the pH measured according to GB/T 7573-2009 The value is 5.6.
綜上所述，本發明提出一種彈性不織布基材的製造方法，其中透過靜電駐極、感壓膠、超音波黏合、纖維物理性糾結纏繞或以線縫合的介面處理方式，提高彈性不織布與支撐材之間的結合力，因此，有利於後加工點膠製程的進行，且在裁切時有助於裡襯布之間剝離，提升使用上的便利性，且不影響彈性及手感。另一方面，在彈性不織布基材的製造方法中，本發明對例如是聚酯、聚醯胺或聚烯烴熱塑性彈性體進行熔噴製程，以形成具有紋路的彈性不織布，紋路有助於改善CD方向上的彈性。 In summary, the present invention provides a method for manufacturing an elastic nonwoven substrate, wherein the elastic non-woven fabric and the support are improved by means of electrostatic electret, pressure sensitive adhesive, ultrasonic bonding, physical entanglement of fibers, or interfacial treatment by wire stitching. The bonding force between the materials is therefore advantageous for the post-processing dispensing process, and helps to peel off the lining cloth during cutting, improving the convenience of use without affecting the elasticity and the hand feeling. On the other hand, in the manufacturing method of the elastic nonwoven substrate, the present invention performs a melt blowing process on, for example, a polyester, a polyamide or a polyolefin thermoplastic elastomer to form an elastic nonwoven fabric having a texture, and the texture contributes to the improvement of the CD. Flexibility in direction.
