This Summary is not an extensive overview of the disclosure, and is not intended to be an The basic spirit and other objects of the present invention, as well as the technical means and implementation aspects of the present invention, can be readily understood by those of ordinary skill in the art.
第1圖為依照本發明一實施例所得之一種耐隆複合纖維的外形，其具有自發捲縮而形成螺旋捲曲的特性。 Fig. 1 is a view showing the appearance of an endurance-resistant composite fiber obtained by spontaneously crimping to form a spiral crimp according to an embodiment of the present invention.
第2圖為習知一種假撚耐隆紗線的外形。 Fig. 2 is a view showing the appearance of a conventional false ruthenium-resistant yarn.
第3圖為習知一種全延伸耐隆紗線的外形。 Figure 3 is a diagram showing the appearance of a fully extended endurance yarn.
依據上述，提供一種耐隆複合纖維與其織物。此耐隆複合纖維能自發捲縮，且其織物具有優異的彈性，無須假撚加工就能讓織物的伸長回復率超過95%。在下面的敘述中，將會介紹上述之耐隆複合纖維與其織物的例示結構與其例示之製造方法。為了容易瞭解所述實施例之故，下面將會提供不少技術細節。當然，並不是所有的實施例皆需要這些技術細節。同時，一些廣為人知之結構或元件，僅會以示意的方式在附圖中繪出，以適當地簡化附圖內容。 According to the above, an endurance composite fiber and a fabric thereof are provided. The Nylon composite fiber can be self-retracted, and the fabric has excellent elasticity, and the elongation recovery rate of the fabric can be made more than 95% without false twisting. In the following description, the above-described exemplary structure of the Nylon composite fiber and the woven fabric thereof and the exemplified manufacturing method thereof will be described. In order to facilitate an understanding of the described embodiments, a number of technical details are provided below. Of course, not all embodiments require these technical details. In the meantime, some well-known structures or elements are only shown in the drawings in a schematic manner to appropriately simplify the drawing.
耐隆複合纖維包括由第一耐隆纖維與第二耐隆纖維所組成的並列型(side-by-side)纖維或偏心芯鞘型(eccentric core-sheath)纖維。 The Nylon composite fiber includes a side-by-side fiber or an eccentric core-sheath fiber composed of a first nylon fiber and a second nylon fiber.
第一耐隆纖維的組成包含具有長脂肪碳鏈的長鏈聚醯胺(polyamide)。由於第一耐隆纖維可以經充份延 伸後而讓長鏈聚醯胺的長脂肪碳鏈順向排列而結晶，所以第一耐隆纖維具有較佳之尺寸安定性。亦即，第一耐隆纖維具有較低的殘餘內應力及沸縮(boiling water shrinkage)。 The composition of the first nylon fiber comprises a long chain polyamine having a long fatty carbon chain. Since the first nylon fiber can be fully extended After stretching, the long aliphatic carbon chains of the long-chain polyamine are aligned and crystallized, so that the first nylon fiber has better dimensional stability. That is, the first nylon fiber has a lower residual internal stress and boiling water shrinkage.
第二耐隆纖維的組成包含具有聚醚鏈段的聚醚修飾聚醯胺。由於聚醚修飾聚醯胺的聚醚鏈段較柔軟，所以即使第二耐隆纖維經延伸後，讓排列不規則的分子產生順向排列，也不易讓順向排列的分子鏈段納入晶格而產生結晶。所以，纖維會保有較高的殘餘內應力及沸縮。 The composition of the second nylon fiber comprises a polyether modified polyamine having a polyether segment. Since the polyether segment of the polyether modified polyamine is soft, even if the second nylon fiber is stretched, the irregularly arranged molecules are arranged in a forward direction, and it is difficult to incorporate the aligned molecular segments into the crystal lattice. And produce crystals. Therefore, the fiber retains high residual internal stress and boiling.
因此，由上述第一耐隆纖維與第二耐隆纖維所組成的耐隆複合纖維，在經過張力延伸、熱處理(例如以沸水處理)或上述兩種處理後，會因為第一耐隆纖維與第二耐隆纖維的不同尺寸安定性而產生螺旋狀捲曲(如第1圖所示)，進而提供纖維伸展所需的一定延伸長度。因此，在延伸耐隆複合纖維後，具有聚醚鏈段的第二耐隆纖維可以協助耐隆複合纖維回復到原來的長度，而含有長脂肪碳鏈的第一耐隆纖維則可以協助穩定耐隆複合纖維的捲曲度。所以，使用上述耐隆複合纖維所形成的耐隆織物可以具有經久耐用的彈性。上述之自發產生螺旋捲曲的耐隆複合纖維與一般所謂由的假撚全延伸耐隆紗線(如第2圖所示)在外形上還是有所不同。本揭露書的耐隆複合纖維的捲區度較大，因此也較有彈性。至於全延伸耐隆紗線(如第3圖所示)，則是整條紗線完全沒有任何捲曲，因此使其缺乏彈性。 Therefore, the Nylon composite fiber composed of the first Nylon fiber and the second Nylon fiber may be subjected to tension stretching, heat treatment (for example, treatment with boiling water) or both treatments, because the first Nylon fiber and The different dimensional stability of the second nylon fiber produces a helical crimp (as shown in Figure 1) which in turn provides a certain extension of the length required for fiber stretching. Therefore, after extending the nylon-resistant composite fiber, the second nylon fiber having the polyether segment can assist the nylon fiber to return to the original length, and the first nylon fiber containing the long fat carbon chain can help stabilize the resistance. The degree of curl of the composite fiber. Therefore, the endurance fabric formed using the above-mentioned nylon-resistant composite fiber can have durability that is durable. The above-mentioned spontaneously produced spiral-curled Nylon composite fiber is different in appearance from the so-called false-twisted fully extended Nylon yarn (as shown in Fig. 2). The Nylon composite fiber of the present disclosure has a large volume and is therefore more elastic. As for the fully extended Nylon yarn (as shown in Figure 3), the entire yarn is completely free of any curl, thus making it inelastic.
上述長鏈聚醯胺是由具有m個碳的直鏈脂肪二胺與具有n個碳的第一直鏈脂肪二羧酸所聚合而成。為了 要讓長鏈聚醯胺具有較佳的結晶性，(n-2)的數值較佳為(m-2)數值的整數倍。例如，長鏈聚醯胺可為耐隆6.10、耐隆6.14或耐隆10.10。 The long-chain polyamine is polymerized by a linear aliphatic diamine having m carbons and a first linear aliphatic dicarboxylic acid having n carbons. in order to In order for the long-chain polyamine to have a preferable crystallinity, the value of (n-2) is preferably an integral multiple of the value of (m-2). For example, the long chain polyamine can be Nylon 6.10, Nylon 6.14 or Nylon 10.10.
上述聚醚修飾聚醯胺是由內醯胺(lactam)、聚醚二胺(polyether diamide)與第二直鏈脂肪二羧酸所共聚而成。聚合方法已揭露在Journal of Applied Polymer Science Volume 126,Issue S2,pages E206-E217,25 November 2012[Synthesis and characterization of polyethylene oxide and nylon-6 copolymer in a fiber form]。 The polyether modified polyamine is obtained by copolymerization of lactam, polyether diamide and a second linear aliphatic dicarboxylic acid. Polymerization methods have been disclosed in Journal of Applied Polymer Science Volume 126, Issue S2, pages E206-E217, 25 November 2012 [Synthesis and characterization of polyethylene oxide and nylon-6 copolymer in a fiber form].
內醯胺例如可具有4-12個碳。聚醚二胺在相鄰二氧原子間具有2-6個碳，例如可為聚***二胺、聚丁醚二胺或聚己醚二胺。聚醚二胺的平均分子量約為400-5000，例如可為400、700、1000、1500、2000、2500、3000、3500、4000、4500或5000。第二直鏈脂肪二羧酸例如可具有6-12個碳。在聚合聚醚修飾聚醯胺所添加單體的總量中，聚醚二胺的添加量為3-20wt%，例如5-12wt%。舉例來說，聚醚二胺的添加量可為3、4、5、6、7、8、9、10、11或12wt%。 The mesaconamine may have, for example, 4 to 12 carbons. The polyether diamine has 2 to 6 carbons between adjacent dioxygen atoms, and may be, for example, polyether diamine, polybutylene diamine or polyhexyl ether diamine. The polyether diamine has an average molecular weight of about 400 to 5,000, and may be, for example, 400, 700, 1000, 1500, 2000, 2500, 3000, 3500, 4000, 4500 or 5000. The second linear aliphatic dicarboxylic acid may have, for example, 6 to 12 carbons. The polyether diamine is added in an amount of from 3 to 20% by weight, for example from 5 to 12% by weight, based on the total amount of the monomers added by the polyether-modified polyamine. For example, the polyether diamine may be added in an amount of 3, 4, 5, 6, 7, 8, 9, 10, 11 or 12% by weight.
上述具有螺旋捲曲之耐隆複合纖維可以下述方法來製備之。首先，長鏈聚醯胺與聚醚修飾聚醯胺先一起進行熔融紡絲形成耐隆複合纖維。然後，利用張力來延伸所得之耐隆複合纖維，可以讓耐隆複合纖維產生螺旋捲曲。接著，耐隆複合纖維還可再以沸水處理，來增加耐隆複合纖維的螺旋密度。 The above-mentioned nylon-clad composite fiber having a spiral crimp can be produced by the following method. First, the long-chain polyamine is melt-spun together with the polyether-modified polyamine to form an endurance-resistant composite fiber. Then, by using the tension to extend the obtained Nylon-resistant composite fiber, the Nylon composite fiber can be spirally curled. Next, the Nylon composite fiber can be further treated with boiling water to increase the spiral density of the Nylon composite fiber.
在此實施例中，利用熔融紡絲來製備不同的耐隆並列型複合纖維。 In this embodiment, different spin-resistant side-by-side composite fibers were prepared by melt spinning.
在實驗例1-3中，長鏈聚醯胺為耐隆6.10，聚醚修飾聚醯胺由己內醯胺、聚***二胺與己二酸所共聚而成。聚***二胺的添加量與平均分子量分別為8wt%與2000。實驗例1-3之長鏈聚醯胺與聚醚修飾聚醯胺的重量比分別為60：40、50：50與40：60。 In Experimental Example 1-3, the long-chain polyamine was Nylon 6.10, and the polyether-modified polyamine was copolymerized from caprolactam, polyether diamine and adipic acid. The addition amount and average molecular weight of the polyether diamine were 8 wt% and 2000, respectively. The weight ratios of the long-chain polyamine to the polyether-modified polyamine of Experimental Example 1-3 were 60:40, 50:50 and 40:60, respectively.
在實驗例4-6中，長鏈聚醯胺為耐隆6.10，聚醚修飾聚醯胺由己內醯胺、聚丁醚二胺與己二酸所共聚而成。聚丁醚二胺的添加量與平均分子量分別為0.82wt%與1000。實驗例4-6之長鏈聚醯胺與聚醚修飾聚醯胺的重量比分別為60：40、50：50與40：60。 In Experimental Examples 4-6, the long-chain polyamine was Nylon 6.10, and the polyether modified polyamine was copolymerized from caprolactam, polybutylene diamine and adipic acid. The amount of polybutylene diamine added and the average molecular weight were 0.82 wt% and 1000, respectively. The weight ratios of the long-chain polyamine to the polyether-modified polyamine of Experimental Examples 4-6 were 60:40, 50:50 and 40:60, respectively.
在比較例1中，是將實驗例5的聚醚修飾聚醯胺由耐隆6所取代。在比較例2中，是將實驗例5的長鏈聚醯胺由耐隆6所取代。在比較例3中，長鏈聚醯胺為耐隆11，聚醚修飾聚醯胺與實驗例2相同。比較例1-3之長鏈聚醯胺與聚醚修飾聚醯胺的重量比皆為50：50。 In Comparative Example 1, the polyether-modified polyamine of Experimental Example 5 was substituted with Nile-6. In Comparative Example 2, the long-chain polyamine of Experimental Example 5 was replaced by Nylon 6. In Comparative Example 3, the long-chain polyamine was london 11, and the polyether-modified polyamine was the same as Experimental Example 2. The weight ratio of the long-chain polyamine to the polyether-modified polyamine of Comparative Examples 1-3 was 50:50.
相關的製備參數整理在下面的表一中。 The relevant preparation parameters are organized in Table 1 below.
在實驗例1-3與4-6中，改變長鏈聚醯胺與聚醚修飾聚醯胺的重量比，以測試所得耐隆複合纖維的不同特性。 In Experimental Examples 1-3 and 4-6, the weight ratio of the long-chain polyamine to the polyether-modified polyamine was changed to test the different characteristics of the obtained nylon-resistant composite fiber.
首先，測量所得耐隆複合纖維經熱縮處理後的原絲捲縮率(crimp contraction；CC)，所得的測量結果列在下面的表二中。原絲捲縮率的測量方法如下。讓測試纖維先負重0.22g/denier(即2g/tex)10秒鐘，測得的長度為L1。然後，自測試纖維上卸下負重，置於160℃下30分鐘。再來，讓測試纖維負重0.011g/denier(即0.1g/tex)10分鐘，測得的長度為L2。因此，原絲捲縮率用下面的算式(1)來計算。 First, the shrinkage ratio (CC) of the obtained Nylon composite fiber after heat shrinkage treatment was measured, and the obtained measurement results are shown in Table 2 below. The measurement method of the raw yarn crimping rate is as follows. The test fiber was first loaded with a load of 0.22 g/denier (i.e., 2 g/tex) for 10 seconds, and the measured length was L1. The load was then removed from the test fibers and placed at 160 ° C for 30 minutes. Further, the test fiber was loaded with a load of 0.011 g/denier (i.e., 0.1 g/tex) for 10 minutes, and the measured length was L2. Therefore, the original yarn crimping ratio is calculated by the following formula (1).
CC(%)=(L1-L2)/L1×100% (1) CC(%)=(L1-L2)/L1×100% (1)
此外，也測量所得耐隆複合纖維的強度，以評估紡絲穩定度。纖維強度的測量方法為依照ASTM4258標準進行。以實用角度而言，纖維強度大於3.5gf/d時，已足以符合多數產業應用之需求。 In addition, the strength of the obtained Nylon composite fiber was also measured to evaluate the spinning stability. The fiber strength is measured in accordance with ASTM 4258. From a practical point of view, fiber strength greater than 3.5gf / d is sufficient to meet the needs of most industrial applications.
在實驗例1-3中，聚醚修飾聚醯胺的單體含有聚***二胺，測得之原絲捲縮率都大於18%，而且當長鏈聚醯胺與聚醚修飾聚醯胺的重量比為40：60時有最大的原絲捲縮率(24.9%，實驗例3)。但是，比較實驗例2與比較例3，當實施例2的耐隆6.10被比較例3的耐隆11取代後， 原絲捲縮率從24.0%大幅降低至10.9%。此結果顯示雖然耐隆11也具有長碳脂肪鏈，但是長碳脂肪鏈顯然不是增加原絲捲縮率的唯一因素。長鏈聚醯胺中之長碳脂肪鏈仍須具有適合的長度，讓長碳脂肪鏈適於排列與結晶，在充分延伸後，才能讓第一耐隆纖維具有良好的尺寸穩定性。 In Experimental Example 1-3, the monomer of the polyether modified polyamine contains polyetherdiamine, and the measured filament shrinkage ratio is more than 18%, and when the long chain polyamine and the polyether are modified polyamine The maximum raw yarn crimp ratio (24.9%, Experimental Example 3) was obtained at a weight ratio of 40:60. However, comparing Experimental Example 2 with Comparative Example 3, when Nylon 6.10 of Example 2 was replaced by Nylon 11 of Comparative Example 3, The raw yarn crimping rate was greatly reduced from 24.0% to 10.9%. This result shows that although Nylon 11 also has a long carbon fat chain, the long carbon fat chain is clearly not the only factor that increases the rate of shrinkage of the raw silk. The long carbon aliphatic chain in the long-chain polyamine needs to have a suitable length, so that the long carbon aliphatic chain is suitable for alignment and crystallization, and after sufficient extension, the first nylon fiber has good dimensional stability.
在實驗例4-6中，聚醚修飾聚醯胺的單體含有聚丁醚二胺，測得之原絲捲縮率都大於24%，而且當長鏈聚醯胺與聚醚修飾聚醯胺的重量比為40：60時有最大的原絲捲縮率(29.4%，實驗例6)。但是，不論是實驗例5之長鏈聚醯胺或聚醚修飾聚醯胺被耐隆6取代後的比較例1或比較例2，原絲捲縮率就大幅降低為10.5%或8.0%。此結果顯示實驗例4-6之耐隆並列型複合纖維可織造出具有高伸長回復率的彈性織物，不需要再經假撚(false twist)加工，或添加Spandex等的彈性纖維。 In Experimental Examples 4-6, the monomer of the polyether modified polyamine contained polybutylene diamine, and the measured filament shrinkage ratio was more than 24%, and when the long-chain polyamine and polyether modified polyfluorene The maximum raw silk crimp ratio (29.4%, Experimental Example 6) was obtained when the weight ratio of the amine was 40:60. However, in Comparative Example 1 or Comparative Example 2 in which the long-chain polyamine or the polyether-modified polyamine of Experimental Example 5 was substituted with Nile 6, the raw yarn crimping ratio was drastically reduced to 10.5% or 8.0%. This result shows that the Nylon-side juxtaposed composite fibers of Experimental Examples 4 to 6 can be woven with an elastic fabric having a high elongation recovery ratio, which is not required to be subjected to false twist processing, or an elastic fiber such as Spandex or the like is added.
纖維強度方面，實驗例1-6的纖維強度皆大於3.5gf/d。此結果顯示這些耐隆複合纖維的強度已足以符合多數產業應用之需求。實驗例1-6之良好的纖維強度主要是因為長鏈聚醯胺與聚醚修飾聚醯胺間的良好相容性，因為兩者的組成皆為耐隆。 In terms of fiber strength, the fiber strengths of Experimental Examples 1-6 were all greater than 3.5 gf/d. This result shows that the strength of these nylon-resistant composite fibers is sufficient to meet the needs of most industrial applications. The good fiber strength of Experimental Examples 1-6 was mainly due to the good compatibility between the long-chain polyamine and the polyether-modified polyamine, since both compositions were resistant to loning.
讓上述實驗例4-6與比較例1-3的耐隆複合纖維編織成各耐隆織物。實驗例4-6與比較例1-3之經紗的紗線規格與編織密度分別為70d/24f DTY與92根/吋，緯紗的 紗線規格與編織密度分別為並列型70d/24f SDY與80根/吋。在此測量了各耐隆織物的伸長回復率與耐磨耗性，數據列在下面的表三中。 The Nylon composite fibers of the above Experimental Examples 4-6 and Comparative Examples 1-3 were woven into individual endurance fabrics. The yarn specifications and weaving densities of the warp yarns of Experimental Examples 4-6 and Comparative Examples 1-3 were 70d/24f DTY and 92/tw, respectively, and the weft yarns. The yarn size and weaving density are 70d/24f SDY and 80/s, respectively. The elongation recovery and wear resistance of each of the Nylon fabrics were measured here, and the data are listed in Table 3 below.
在實驗例4-6中，所得耐隆織物的伸長回復率皆超過90%，較比較例1-3的耐隆織物伸長回復率要大許多(73-82%)。因此實驗例4-6之耐隆織物可以提供較佳的穿著舒適性。 In Experimental Examples 4-6, the elongation recovery ratio of the obtained Nylon fabric was more than 90%, which was much larger than that of Comparative Examples 1-3 (73-82%). Therefore, the Nylon fabric of Experimental Examples 4-6 can provide better wearing comfort.
比較實驗例5與比較例3，唯一的差別為實驗例5的長鏈聚醯胺成分是耐隆6.10，而比較例3的長鏈聚醯胺成分是耐隆11。如前所述，由於耐隆11的結晶性比耐隆6.10要差，讓比較例3之耐隆複合纖維的原絲捲縮率較 差。連帶地，實驗例3所得之耐隆織物的伸長回復率也較差。 Comparing Experimental Example 5 with Comparative Example 3, the only difference was that the long-chain polyamine component of Experimental Example 5 was Nylon 6.10, and the long-chain polyamine component of Comparative Example 3 was Nylon 11. As described above, since the crystallinity of the Nylon 11 is worse than that of the Nylon 6.10, the shrinkage ratio of the raw yarn of the Nylon composite fiber of Comparative Example 3 is higher. difference. Incidentally, the elongation recovery ratio of the Nylon fabric obtained in Experimental Example 3 was also inferior.
至於耐隆織物的耐磨耗性部分，由表三的數據可知實驗例4-6的耐磨耗性皆高於120，是一般耐隆織物的1.2到1.3倍。顯示實驗例4-6的耐隆織物可具有較長的使用壽命。 As for the abrasion resistance portion of the Nylon fabric, it is understood from the data in Table 3 that the abrasion resistance of Experimental Example 4-6 is higher than 120, which is 1.2 to 1.3 times that of the general nylon fabric. The Nylon fabrics showing Experimental Examples 4-6 can have a long service life.
由上述可知，本發明實施例所提供之耐隆複合纖維的第一耐隆纖維包含具有長脂肪碳鏈的長鏈聚醯胺，第二耐隆纖維具有聚醚鏈段的聚醚修飾聚醯胺，讓所得耐隆複合纖維經延伸處理、熱處理或兩者的處理之後，可自發捲縮產生螺旋狀捲曲。耐隆複合纖維的原絲捲縮率可高達20%以上，甚至高達29.4%，讓所得耐隆織物具有經久耐用的伸展性。此外，所得耐隆織物的磨耗性也相當優良，可以讓耐隆織物具有良好的使用壽命。 It can be seen from the above that the first nylon fiber of the Nylon-resistant composite fiber provided by the embodiment of the present invention comprises a long-chain polyamine having a long aliphatic carbon chain, and the second nylon fiber has a polyether modified polyether having a polyether segment. The amine, after the elongation-treated, heat-treated or both of the obtained nylon-resistant composite fibers, can be spontaneously crimped to produce a spiral crimp. The shrinkage rate of the raw yarn of the Nylon composite fiber can be as high as 20% or more, even as high as 29.4%, so that the obtained Nylon fabric has durable stretchability. In addition, the abrasion resistance of the obtained Nylon fabric is also quite excellent, and the Nylon fabric can have a good service life.
雖然本發明已以實施方式揭露如上，然其並非用以限定本發明，任何熟習此技藝者，在不脫離本發明之精神和範圍內，當可作各種之更動與潤飾，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。 Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and the present invention can be modified and modified without departing from the spirit and scope of the present invention.
