Description
本發明係關於絕熱材料之技術領域，且更具體言之，係關於一種製造防水絕熱材料之方法及一種藉由該方法製造之防水絕熱材料。 The present invention relates to the technical field of thermal insulation materials, and more particularly to a method of manufacturing a waterproof thermal insulation material and a waterproof thermal insulation material manufactured by the method.
目前，市場中可獲得之習知絕熱材料主要包括天然棉絮(包括棉花、羊毛、大麻、絲綢、木棉、竹纖維及羽毛絨等)及合成棉絮(諸如，聚酯纖維、卡普綸(kapron)、丙烯酸系纖維、聚丙烯纖維、聚乳酸纖維、纖維素纖維及其類似者)。歸因於天然棉絮(諸如，棉花、羊毛及羽毛絨)之較高回潮率(例如，棉花為8.5%且羊毛為16%)，在高濕度或細雨霧條件下，天然棉絮之絕熱效能大大降低。另一方面，儘管正常合成纖維之回潮率較低(例如，聚酯纖維約為0.4%、聚丙烯纖維為0%且丙烯酸系纖維為2%)，但因為不織布材料之蓬鬆多孔結構，所以水蒸氣或水滴仍可滲透棉絮，以致絕熱效應亦減小。 Currently, the known thermal insulation materials available in the market mainly include natural cotton wool (including cotton, wool, hemp, silk, kapok, bamboo fiber and feather velvet) and synthetic cotton wadding (such as polyester fiber, kapron). , acrylic fibers, polypropylene fibers, polylactic acid fibers, cellulose fibers and the like). Due to the high moisture regain of natural cotton wool (such as cotton, wool and feather velvet) (for example, 8.5% for cotton and 16% for wool), the thermal insulation of natural cotton wadding is greatly improved under high humidity or fine rain and fog conditions. reduce. On the other hand, although the normal synthetic fiber has a low moisture regain (for example, polyester fiber is about 0.4%, polypropylene fiber is 0%, and acrylic fiber is 2%), water is loose because of the porous structure of the non-woven material. The vapor or water droplets are still permeable to the batting so that the adiabatic effect is also reduced.
為了向絕熱材料賦予防水性質，目前已應用許多種技術，包括：藉由在不織布材料上層壓一層功能性材料來達成所預期之保護及防水性質的方法，例如WO 2011019478 A1及US 2010009112 A1；藉由將織物浸泡於處理液中來向織物賦予防水性質之方法，例如JP 8246347；及處理纖維以向纖維賦予防水性質且接著將纖維製造成不 織布材料之方法，例如US 5770308及CN1136613A。然而，在不織布材料上層壓其他層之方法涉及更多處理步驟，增加絕熱材料之重量且對材料之厚度具有負面影響，以致絕熱性質將受到影響。而且就涉及使用處理液浸泡織物或處理纖維之步驟的方法而言，需要大量處理液，此情形不僅增加成本而且可能造成安全及環境關注。 In order to impart a waterproof property to a heat insulating material, a number of techniques have been applied, including: a method of achieving a desired protective and waterproof property by laminating a layer of functional material on a nonwoven material, such as WO 2011019478 A1 and US 2010009112 A1; a method of imparting waterproof properties to a fabric by immersing the fabric in a treatment liquid, such as JP 8246347; and treating the fibers to impart waterproof properties to the fibers and then manufacturing the fibers into no Methods of weaving materials such as US 5770308 and CN1136613A. However, the method of laminating other layers on the non-woven material involves more processing steps, increasing the weight of the insulating material and having a negative impact on the thickness of the material, so that the adiabatic properties will be affected. Moreover, in the case of a method involving the step of soaking the fabric or treating the fibers with the treatment liquid, a large amount of treatment liquid is required, which not only increases the cost but also causes safety and environmental concerns.
本發明意欲提供一種以快速、安全及低成本方式製造防水絕熱不織布材料之方法及一種藉由該方法製造之防水絕熱不織布材料。 The present invention is intended to provide a method of manufacturing a waterproof and heat-insulating nonwoven fabric material in a fast, safe and low-cost manner and a waterproof and heat-insulating nonwoven fabric material produced by the method.
為了達成以上目標，在一態樣中，本發明提供一種製造防水絕熱不織布材料之方法，該方法包含以下步驟：以0.5g/m2至20g/m2之比率將防水試劑噴灑至由主要纖維及視情況選用之低熔點纖維藉由不織布製程形成之網的一表面或兩個表面上，且接著在110℃至200℃之溫度下加熱該網歷時2分鐘至10分鐘。 In order to achieve the above object, in one aspect, the present invention provides a method of manufacturing a waterproof and heat-insulating nonwoven fabric, the method comprising the steps of: spraying a water repellent agent to a main fiber at a ratio of 0.5 g/m 2 to 20 g/m 2 And optionally, the low melting point fibers are heated on one or both surfaces of the web formed by the non-woven process, and then heated at a temperature of 110 ° C to 200 ° C for 2 minutes to 10 minutes.
在另一態樣中，本發明提供一種藉由根據本發明之方法製造之防水絕熱不織布材料。 In another aspect, the invention provides a waterproof, thermally insulating nonwoven material made by the method of the invention.
在本發明中，防水試劑可為選自有機氟型防水試劑、聚矽氧型防水試劑、矽氟型防水試劑及烴防水試劑中之至少一者。 In the present invention, the water repellent agent may be at least one selected from the group consisting of an organic fluorine type water repellent agent, a polyfluorene type water repellent agent, a fluorene type water repellent agent, and a hydrocarbon water repellent agent.
在本發明中，在形成網之後，將防水試劑噴灑至網之一表面或兩個表面上。接著，在加熱之後，防水試劑在絕熱不織布材料之表面層中之各纖維的表面上形成膜，以便形成防水網。所得絕熱不織布材料具有由防水試劑之均勻成膜形成之防水表面層，且該防水表面層之表面能降低，進而達成防水性質。 In the present invention, after forming the web, the water repellent agent is sprayed onto one surface or both surfaces of the web. Next, after heating, the water repellent agent forms a film on the surface of each of the fibers in the surface layer of the heat insulating nonwoven fabric to form a waterproof net. The obtained heat-insulating non-woven fabric material has a water-repellent surface layer formed by uniform film formation of a water-repellent agent, and the surface energy of the water-repellent surface layer is lowered, thereby achieving waterproof property.
在根據本發明之絕熱不織布材料包含低熔點纖維的情況下，在加熱時，低熔點纖維熔融且結合至其周圍主要纖維以形成具有一定強度之網。此外，由於在加熱時同時發生低熔點纖維之熔融及防水試劑之成膜，因此在纖維與防水試劑之間產生較高親和力，以使得防水試 劑可更均勻且更穩定地形成防水膜。因此，防水絕熱不織布材料之耐洗性得以增強。 In the case where the heat insulating nonwoven fabric material according to the present invention contains low melting point fibers, upon heating, the low melting point fibers are melted and bonded to the main fibers around them to form a web having a certain strength. In addition, since the melting of the low-melting fiber and the film formation of the water repellent agent occur simultaneously during heating, a high affinity is generated between the fiber and the water repellent agent, so that the waterproof test is performed. The agent can form a water repellent film more uniformly and more stably. Therefore, the wash durability of the waterproof and heat-insulating nonwoven fabric is enhanced.
根據本發明之防水絕熱不織布材料在乾燥及潮濕兩種條件下具有良好的防水性質及優良的保暖效應，而且可以快速、安全及低成本方式來製造。 The waterproof and heat-insulating non-woven fabric material according to the present invention has good waterproof property and excellent heat-preserving effect under both dry and wet conditions, and can be manufactured in a fast, safe and low-cost manner.

在本發明中，在形成網之後，將防水試劑噴灑至網之一表面或兩個表面上。接著，加熱網，直至低熔點纖維(若存在的話)熔融且結合至周圍主要纖維以形成具有一定強度之網；同時，防水試劑均勻地形成膜，以便產生防水網。 In the present invention, after forming the web, the water repellent agent is sprayed onto one surface or both surfaces of the web. Next, the web is heated until the low melting fibers (if present) are melted and bonded to the surrounding primary fibers to form a web having a strength; at the same time, the water repellent agent uniformly forms a film to create a waterproof mesh.
將防水試劑之噴灑量控制在0.5g/m2至20g/m2且較佳2g/m2至10 g/m2之範圍內，以使得可將防水試劑均勻地分佈在絕熱不織布材料之表面上。 The spraying amount of the water repellent agent is controlled within a range of 0.5 g/m 2 to 20 g/m 2 and preferably 2 g/m 2 to 10 g/m 2 so that the water repellent agent can be uniformly distributed on the surface of the heat insulating nonwoven fabric material. on.
