请参照图4至图6，丝束运行于喂入分丝张力辊1400至第一对牵伸热辊1600时，丝束于喂入分丝张力辊1400的绕经旋向为逆时针方向，丝束于第一对牵伸热辊1600的绕 经旋向为逆时针旋向。其中，喂入分丝张力辊1400与丝束N表面20直接接触、加热，第一对牵伸热辊1600与丝束N表面20直接接触、加热。请参照图7至图9，丝束于第二对牵伸热辊1700的绕经旋向为顺时针方向，第二对牵伸热辊1700与丝束M表面10直接接触、加热。请参照图10至图12，丝束于第三对牵伸热辊1800的绕经旋向为逆时针方向，第三对牵伸热辊1800与丝束N表面20直接接触、加热。请参照图13至图15，丝束于第四对牵伸热辊1900的绕经旋向为顺时针方向，第四对牵伸热辊1900与丝束M表面10直接接触、加热。
从而从第一对牵伸热辊1600至第四对牵伸热辊1900，依次对丝束N表面20、丝束M表面10、丝束N表面20、丝束M表面10接触加热，有利于提高纤维的结晶度和取向度，可以逐渐提高纤维的强度和模量，配合多级牵伸热辊实现逐级牵伸，能够纺制55dtex-2222dtex的生物基聚酰胺产业用丝，从而可以用于55dtex-111dtex细旦生物基聚酰胺纤维、1670dtex-2222dtex粗旦生物基聚酰胺纤维的纺制。
在一些实施方式中，请参照图16至图18，丝束于第五对牵伸热辊2000的绕经旋向为顺时针，第五对牵伸热辊2000与丝束M表面10直接接触、加热，从而使丝束从如图1中的右侧垂下，经终网络部件2100进入卷绕机，有利于装置的整体布置。
在一些实施方式中，请参照图1至图18，装置按照丝束行进方向可以依次包括喂入分丝张力辊1400、第一加热板1510、第一对牵伸热辊1600、第二加热板1520、第二对牵伸热辊1700、第三加热板1530、第三对牵伸热辊1800、第四加热板1540、第四对牵伸热辊1900、第五加热板1550以及第五对牵伸热辊2000，第一加热板1510、第二加热板1520、第三加热板1530、第四加热板1540以及第五加热板1550均对相邻两辊间区域的丝束进行加热。
在一些实施方式中，丝束于第一对牵伸热辊1600进行第一次拉伸，考虑要使丝束保持一定的张力，通过第一加热板1510先给丝束两面进行加热预热后，再进入第一对牵伸热辊1600，有利于克服初次牵伸易出现断头、可纺性差等问题；设于第一对牵伸热辊1600与第二对牵伸热辊1700之间的第二加热板1520，有利于提高纤维的结晶度和取向度，可以逐渐提高纤维的强度和模量；设于第二对牵伸热辊1700与第三对牵伸热辊1800之间的第三加热板1530，提高了丝束的内外温度一致性，提高了丝束的受热均匀性，以利于后道加热、牵伸；设于第三对牵伸热辊1800与第四对牵伸热辊1900之间的第四加热板1540，进一步提高了丝束的内外温度一致性，提高了丝束的受热均匀性，以利于后道加热、牵伸；设于第四对牵伸热辊1900与第五对牵伸热辊2000之间的第五加热板1550，进一步提高了丝束的内外温度一致性，提高了丝束的受热均匀性，以利于后道定型回缩。
在一些实施方式中，如图4所示，喂入分丝张力辊1400采用固定冷辊1410配合可调角度分丝辊1420，而第一对牵伸热辊1600、第二对牵伸热辊1700、第三对牵伸热辊1800、第四对牵伸热辊1900以及第五对牵伸热辊2000均采用可调角度热辊配合可调角度热辊。
第一对牵伸热辊1600为低温辊，对丝束进行初步加热；而第二对牵伸热辊1700、第三对牵伸热辊1800、第四对牵伸热辊1900以及第五对牵伸热辊2000均为高温辊，对丝束进行进一步的加热，以牵伸、松弛定型等。
喂入分丝张力辊1400与第一对牵伸热辊1600的牵伸比保持在1：(1.04-1.08)，使丝束保持一定的张力；第一对牵伸热辊1600与第二对牵伸热辊1700的牵伸倍数为1.5至3.5倍，这级牵伸有利于高取向、较低结晶度；第二对牵伸热辊1700与第三对牵伸热辊1800的牵伸倍数为2.0至3.5倍，形成二次加热和牵伸；第三对牵伸热辊1800与第四对牵伸热辊1900的牵伸倍数一般为1.7至2.5倍，提高纤维的均匀性和牵伸倍数，提高丝束强度；第四对牵伸热辊1900与第五对牵伸热辊2000的牵伸倍数为0.9-1.0倍，二者之间纤维有一定的回缩，对牵伸后的丝束进行定型，消除纤维因高速牵伸产生的应力。以便更好控制低收缩率。
本实施例的一种产业用生物基聚酰胺纺丝牵伸卷绕装置以纺制55dtex-2222dtex的生物基聚酰胺产业用丝，可以包括纺制55dtex-111dtex的生物基聚酰胺产业用丝，以及纺制1670dtex-2222dtex的生物基聚酰胺产业用丝。
在一些实施方式中，生物基聚酰胺纤维丝束经导丝部件1300将丝束进入丝路转向导丝，将丝路改为0°-90°再进入喂入分丝张力辊1400，喂入分丝张力辊1400采用固定冷辊1410(φ(110-220)×400mm)和可调角度分丝辊1420(φ(55-110)×400mm)组合使用，辊壳表面为氧化铬+氧化铝，经过90°转向的丝束竖向下移、至相切地接触固定冷辊1410的圆柱表面有效区的后端，如图4所示。请结合图5，后丝束从固定冷辊1410圆柱表面左侧逆时针的缠绕半圈后从固定冷辊1410圆柱表面右侧相切的牵引出来后，进入可调角度分丝辊1420圆柱表面右侧，逆时针缠绕半圈再从可调角度分丝辊1420圆柱表面左侧相切的拉出后进入固定冷辊1410圆柱表面左侧，此时由于分丝辊具有调节角度的作用；可调角度分丝辊1420圆柱形辊体前段向下倾斜，因此从可调角度分丝辊1420圆柱表面缠绕半圈的丝束会在其辊体的表面向辊体的前端产生一定的位置移动(如图5所示)，如此丝束逆时针的连续在固定冷辊1410与可调角度分丝辊1420之间缠绕1圈～5圈，最后一圈缠绕完后从固定冷辊1410圆柱辊面的前端的下切点逆时针的牵引出，在喂入分丝张力辊1400部件上缠绕，无加热，其作用是将初生的丝束握持住，并给予丝束一定的速度。丝束在喂入分丝张力辊1400的牵引下，冷却成型，完成纺程牵伸，形成初生纤维。速度为550-750m/min，依次进入第一加热板1510，此时，与喂入分丝张力辊1400辊壳表面相接触的丝束表面为丝束N表面20，n根丝束在辊壳表面均匀铺开，这样可以充分提高纺纱张力以降低纺成纤维的摇摆。由于喂入分丝张力辊1400与第一对牵伸热辊1600保持1：(1.04-1.08)的速比，使丝束保持一定的张力，需要给准备牵伸的丝束进行预热，丝束被第一对牵伸热辊1600牵引，经过第一加热板1510，在第一加热板1510内，n根丝束的M、N两面均被加热。
在纺55dtex-111dtex时，总纤度和单丝纤度都比较低，初生纤维在初次进行牵伸易出现断头等异常现象，需要相对低温的加热环境，如图5所示，喂入分丝张力辊1400速度为720m/min出来的n根丝束经过第一加热板1510，在第一加热板1510内，n根丝束的M、N两面均被加热，此时加热温度比较低为50-65℃，给截面较细的丝束一个持续的低温预热，在加热板内让丝束里面尽最大可能受热，提高热的穿透力，依次进入第一对牵伸热辊1600。第一对牵伸热辊1600采用可调角度热辊+可调角度热辊，热辊外壳表面为氧化铬 +氧化铝，对辊尺寸(2×φ(190-250)×(350-450)mm)，此对辊为低温辊，丝束在第一对牵伸热辊1600的辊面上缠绕6.5圈～7.5圈，温度设定为75-100℃，在一些实施方式中为90℃，纺速700-800m/min，丝束在第一对牵伸热辊1600表面稳定铺开，丝束在第一对牵伸热辊1600的辊面和辊面上逆时针的缠绕6.5圈～7.5圈，此时丝束在辊壳表面加热的丝束表面为N表面。
在纺1670dtex-2222dtex时，总纤度和单丝纤度都比较高，初生纤维在初次进行牵伸同样易出现断头等异常现象，同时总纤度和单丝纤度过高又会造成纺丝时可纺性差，丝束弯曲强度过高，手感硬。需要相对高温的加热环境，如图4和图5所示，喂入分丝张力辊1400速度为650m/min出来的n根丝束经过第一加热板1510，在第一加热板1510内，n根丝束的M、N两面均被加热，此时加热温度比较低为70-90℃，给截面较细的丝束一个持续的较高温预热，在加热板内让丝束里面尽最大可能受热，提高热的穿透力，依次进入第一对牵伸热辊1600采用可调角度热辊+可调角度热辊，热辊外壳表面为氧化铬+氧化铝，对辊尺寸(2×φ(190-250)×(350-450)mm)，此对辊为低温辊，丝束在第一对牵伸热辊1600的辊面上缠绕6.5圈～7.5圈，温度设定为75-100℃，在一些可实施方式中为90℃，纺速700-800m/min，丝束在第一对牵伸热辊1600表面稳定铺开，丝束在第一对牵伸热辊1600的辊面和辊面上缠绕6.5圈～7.5圈，此时丝束在辊壳表面加热的丝束表面为N表面。
在一些实施方式中，如图7至图9所示，丝束在第一对牵伸热辊1600上缠绕后，从第一对牵伸热辊1600右辊牵引出后传至第二加热板1520，在第二加热板1520内，n根丝束的M、N两面均被加热，n根丝束在第二对牵伸热辊1700左辊表面均匀铺开，此时丝束在辊壳表面加热的丝束表面为M表面。第二对牵伸热辊1700采用可调角度热辊+可调角度热辊，热辊外壳表面为氧化铬+氧化铝，此辊为高温辊，对辊尺寸(2×φ(190-250)×(350-450)mm)。第一对牵伸热辊1600为低温辊，温度设定为75-100℃，第二对牵伸热辊1700为高温辊，温度设定为110-145℃，可以使丝束温度逐步稳定上升，有利于使纤维逐渐取向、结晶，以达到生物基聚酰胺产业用丝纤维的力学性能。放置第二加热板1520使每根丝单独从加热器间通过，并将在第二对牵伸热辊1700表面稳定铺开，提高了丝束的内外温度一致性，提高了丝束的受热均匀性，以利于后道加热、牵伸。从第一对牵伸热辊1600到第二对牵伸热辊1700，丝束受热面反过来了，此时丝束在辊壳表面加热的丝束表面为M表面。如图II放大图所示，此过程丝束的M表面也受到了加热，再加上第二加热板1520的加热平衡，有利于提高纤维的结晶度和取向度，可以逐渐提高纤维的强度和模量。第二加热板1520设定温度95-115℃，丝束在经过第二加热板1520后传至第二对牵伸热辊1700。丝束在第二对牵伸热辊1700的辊面上顺时针的缠绕6.5圈～7.5圈，纺速1680m/min。第一对牵伸热辊1600与第二对牵伸热辊1700牵伸倍数一般为1.5～3.5倍，这级牵伸是为了获得具有高取向、较低结晶度。纺55dtex-111dtex比纺1670dtex-2222dtex总纤度和单丝纤度都低，受热面积小，需要相对低5-10℃的加热环境，由于丝相对细，牵伸比小5％-10％。
在一些实施方式中，如图10至图12所示，丝束在第二对牵伸热辊1700上缠绕后，丝束被第三对牵伸热辊1800牵引，经过第三加热板1530对n根丝束的M、N两面均被加 热。丝束在第三对牵伸热辊1800表面稳定铺开，丝束在第三对牵伸热辊1800的两辊辊面上缠绕6.5圈～7.5圈，n根丝束在辊壳表面均匀铺开，丝束在辊壳表面加热的丝束表面为N表面。从而这级牵伸可获得一定的强力和伸长，纺55dtex-111dtex比纺1670dtex-2222dtex总纤度和单丝纤度都低，受热面积小，需要相对低5-15℃的加热环境，由于丝相对细，牵伸比小4％-12％。第三加热板1530设定温度110-155℃，丝束在经过第三加热板1530后传至第三牵伸热辊，第三对牵伸热辊1800采用可调角度热辊+可调角度热辊，热辊外壳表面为氧化铬+氧化铝，对辊尺寸(2×φ(190-250)×(350-450)mm)，此辊为高温辊，丝束在第三对牵伸热辊1800的辊面上缠绕6.5圈～7.5圈，温度设定为130-150℃，在一些实施方式中为140℃，纺速2520m/min，第二对牵伸热辊1700与第三对牵伸热辊1800牵伸倍数一般为2.0～3.5倍，形成二次加热和牵伸，进一步使丝束温度逐步稳定上升，提高纤维的均匀性和牵伸倍数，提高丝束强度。放置第三加热板1530使每根丝单独从加热器间通过，并将在第三对牵伸热辊1800表面稳定铺开，进一步提高了丝束的内外温度一致性，提高了丝束的受热均匀性，以利于后道加热、牵伸。从第二对牵伸热辊1700到第三对牵伸热辊1800，丝束受热面再次反过来了，此时丝束在辊壳表面加热的丝束表面为N表面。使丝束两面都受到加热，再加上第三加热板1530的加热平衡，有利于提高纤维的结晶度和取向度，可以逐渐提高纤维的强度和模量。
在一些实施方式中，如图13至图15所示，丝束在第三对牵伸热辊1800上缠绕后，丝束被第四对牵伸热辊1900牵引，经过第四加热板1540内n根丝束的M、N两面均被加热。丝束在第四对牵伸热辊1900表面稳定铺开，丝束在第四对牵伸热辊1900的两辊辊面上缠绕6.5圈～7.5圈，n根丝束在辊壳表面均匀铺开,此时丝束在辊壳表面加热的丝束表面为M表面。这级牵伸同样是为了获得一定的强力和伸长，具有一定的预定型作用。纺55dtex-111dtex比纺1670dtex-2222dtex总纤度和单丝纤度都低，受热面积小，需要相对低2-10℃的加热环境，由于丝相对细，牵伸比小2％-8％。第四加热板1540的设定温度为125-195℃，第三对牵伸热辊1800与第四对牵伸热辊1900之间形成第三次加热和牵伸，牵伸倍数一般为1.7～2.5倍，进一步使丝束温度逐步稳定上升，提高纤维的均匀性和牵伸倍数，提高丝束强度。放置第四加热板1540使每根丝单独从加热器间通过，并将在第四对牵伸热辊1900表面稳定铺开，进一步提高了丝束的内外温度一致性，提高了丝束的受热均匀性，以利于后道加热、牵伸。从第三对牵伸热辊1800到第四对牵伸热辊1900，丝束受热面再次反过来了，此时丝束在辊壳表面加热的丝束表面为M表面。使丝束两面都受到加热，再加上第四加热板1540的加热平衡，有利于后续牵伸中结晶区取向度和晶粒尺寸的增加和晶区的完善，丝束在经过第四加热板1540后传至第四对牵伸热辊1900，第四对牵伸热辊1900采用可调角度热辊配合可调角度热辊，热辊外壳表面为陶瓷，对辊尺寸(2×φ(190-235)×(350-400)mm)，此辊为高温辊，温度设定为130-150℃，丝束在第四对牵伸热辊1900的辊面上缠绕6.5圈～7.5圈，纺速3650m/min。
在一些实施方式中，如图16至图18所示，丝束在第四对牵伸热辊1900上缠绕后，丝束被第五对牵伸热辊2000牵引，经过第五加热板1550，第五加热板1550设定温度140-220℃，在第五加热板1550内，n根丝束的M、N两面均被加热。丝束在第五对牵伸 热辊2000表面稳定铺开，丝束在第五对牵伸热辊2000的两辊辊面上缠绕6.5圈～7.5圈，n根丝束在辊壳表面均匀铺开，此时丝束在辊壳表面加热的丝束表面为M表面。这级起到松弛定型作用，纺55dtex-111dtex比纺1670dtex-2222dtex总纤度和单丝纤度都低，受热面积小，需要相对低1-4℃的加热环境，由于丝相对细，松弛比小1％-3％。第四对牵伸热辊1900与第五对牵伸热辊2000牵伸倍数一般为0.9-1.0倍，第五对牵伸热辊2000的速度略低于第四对牵伸热辊，二者之间纤维又有一定的回缩，完成高强丝的定型主要作用是对牵伸后的丝束进行定型，消除纤维因高速牵伸产生的应力。以便更好控制低收缩率。放置第五加热板1550使每根丝单独从加热器间通过，并将在第五对牵伸热辊2000表面稳定铺开，进一步提高了丝束的内外温度一致性，提高了丝束的受热均匀性，以利于后道定型回缩。丝束在经过第五加热板1550后传至第五对牵伸热辊2000，第五对牵伸热辊2000采用可调角度热辊+可调角度热辊，热辊外壳表面为陶瓷，对辊尺寸(2×φ(190-220)×(350-400)mm)，此辊为高温辊，丝束在第五对牵伸热辊2000的辊面上缠绕6.5圈～7.5圈，温度设定为130-210℃，纺速3550m/min。
在一些实施方式中，本实施例的纺丝牵伸卷绕装置用于55dtex-111dtex细旦生物基聚酰胺纤维、1670dtex-2222dtex粗旦生物基聚酰胺纤维的纺制，也可以用于111dtex-1670dtex生物基聚酰胺纤维的纺制。
在一些实施方式中，如图19至图21所示，加热板均可以包括传热块1501和多个加热棒1502，传热块1501设有供丝束穿过的开口槽1503，多个加热棒1502沿开口槽1503长度方向依次排列设置，图中展示三根加热棒1502，加热棒1502的数量还可以有更多选择；加热棒1502均呈钩状布置且形成有钩部和钩槽，钩部内设于传热块1501，钩槽以供丝束穿过。通过本加热板，可对穿过的丝束的两侧进行充分、均匀加热。

喂入分丝张力辊1400与第一对牵伸热辊1600的牵伸比保持在1：(1.04-1.08)，使丝束保持一定的张力；第一对牵伸热辊1600与第二对牵伸热辊1700的牵伸倍数为1.5至3.5倍，这级牵伸有利于高取向、较低结晶度；第二对牵伸热辊1700与第三对牵伸热辊1800的牵伸倍数为2.0至3.5倍，形成二次加热和牵伸；第三对牵伸热辊1800与第四对牵伸热辊1900的牵伸倍数一般为1.7至2.5倍，提高纤维的均匀性和牵伸倍数，提高丝束强度；第四对牵伸热辊1900与第五对牵伸热辊2000的牵伸倍数为0.9-1.0倍，二者之间纤维有一定的回缩，对牵伸后的丝束进行定型，消除纤维因高速牵伸产生的应力。以便更好控制低收缩率。
本实施例的一种产业用生物基聚酰胺纺丝牵伸卷绕联合机以纺制55dtex-2222dtex的生物基聚酰胺产业用丝，可以包括纺制55dtex-111dtex的生物基聚酰胺产业用丝，以及纺制1670dtex-2222dtex的生物基聚酰胺产业用丝。
在一些实施方式中，生物基聚酰胺纤维丝束经导丝部件1300将丝束进入丝路转向导丝，将丝路改为0°-90°再进入喂入分丝张力辊1400，喂入分丝张力辊1400采用固定冷辊1410(φ(110-220)×400mm)和可调角度分丝辊1420(φ(55-110)×400mm)组合使用，辊壳表面为氧化铬+氧化铝，经过90°转向的丝束竖向下移、至相切地接触固定冷辊1410的圆柱表面有效区的后端，如图4所示。结合图5，后丝束从固定冷辊1410圆柱表面左侧逆时针的缠绕半圈后从固定冷辊1410圆柱表面右侧相切的牵引出来后，进入可调角度分丝辊1420圆柱表面右侧，逆时针缠绕半圈再从可调角度分丝辊1420圆柱表面左侧相切的拉出后进入固定冷辊1410圆柱表面左侧，此时由于分丝辊具有调节角度的作用；可调角度分丝辊1420圆柱形辊体前段向下倾斜，因此从可调角度分丝辊1420圆柱表面缠绕半圈的丝束会在其辊体的表面向辊体的前端产生一定的位置移动(如图5所示)，如此丝束逆时针的连续在固定冷辊1410与可调角度分丝辊1420之间缠绕1圈～5圈，最后一圈缠绕完后从固定冷辊1410圆柱辊面的前端的下切点逆时针的牵引出，在喂入分丝张力辊1400部件上缠绕，无加热，其作用是将初生的丝束握持住，并给予丝束一定的速度。丝束在喂入分丝张力辊1400的牵引下，冷却成型，完成纺程牵伸，形成初生纤维。速度为550-750m/min，依次进入第一加热板1510，此时，与喂入分丝张力辊1400辊壳表面相接触的丝束表面为丝束N表面20，n根丝束在辊壳表面均匀铺开，这样可以充分提高纺纱张力以降低纺成纤维的摇摆。由于喂入分丝张力辊1400与第一对牵伸热辊1600保持1：(1.04-1.08)的速比，使丝束保持一定的张力，需要给准备牵伸的丝束进行预热，丝束被第一对牵伸热辊1600牵引，经过第一加热板1510，在第一加热板1510内，n根丝束的M、N两面均被加热。
在纺55dtex-111dtex时，总纤度和单丝纤度都比较低，初生纤维在初次进行牵伸易出现断头等异常现象，需要相对低温的加热环境，如图5所示，喂入分丝张力辊1400速度为720m/min出来的n根丝束经过第一加热板1510，在第一加热板1510内，n根丝束的M、N两面均被加热，此时加热温度比较低为50-65℃，给截面较细的丝束一个持续的低温预热，在加热板内让丝束里面尽最大可能受热，提高热的穿透力，依次进入第一对牵伸热辊1600。第一对牵伸热辊1600采用可调角度热辊+可调角度热辊，热辊外壳表面为氧化铬+氧化铝，对辊尺寸(2×φ(190-250)×(350-450)mm)，此对辊为低温辊，丝束在第一对牵伸热辊1600的辊面上缠绕6.5圈～7.5圈，温度设定为75-100℃，在一些可实施方式中为90℃，纺速700-800m/min，丝束在第一对牵伸热辊1600表面稳定铺开，丝束在第一对牵伸热辊1600的辊面和辊面上逆时针的缠绕6.5圈～7.5圈，此时丝束在辊壳表面加热的丝束表面为N表面。
在纺1670dtex-2222dtex时，总纤度和单丝纤度都比较高，初生纤维在初次进行牵伸同样易出现断头等异常现象，同时总纤度和单丝纤度过高又会造成纺丝时可纺性差，丝束弯曲强度过高，手感硬。需要相对高温的加热环境，如图4和图5所示，喂入分丝张力辊1400速度为650m/min出来的n根丝束经过第一加热板1510，在第一加热板1510内，n根丝束的M、N两面均被加热，此时加热温度比较低为70-90℃，给截面较细的丝束一个持续的较高温预热，在加热板内让丝束里面尽最大可能受热，提高热的穿透力，依次进入第一对牵伸热辊1600采用可调角度热辊+可调角度热辊，热辊外壳表面为氧化铬+氧化铝，对辊尺寸(2×φ(190-250)×(350-450)mm)，此对辊为低温辊，丝束在第一对牵伸热辊1600的辊面上缠绕6.5圈～7.5圈，温度设定为75-100℃，在一些可实施方式中为90℃，纺速700-800m/min，丝束在第一对牵伸热辊1600表面稳定铺开，丝束在第一对牵伸热辊1600的辊面和辊面上缠绕6.5圈～7.5圈，此时丝束在辊壳表面加热的丝束表面为N表面。
在一些实施方式中，如图7至图9所示，丝束在第一对牵伸热辊1600上缠绕后，从第一对牵伸热辊1600右辊牵引出后传至第二加热板1520，在第二加热板1520内，n根丝束的M、N两面均被加热，n根丝束在第二对牵伸热辊1700左辊表面均匀铺开，此时丝束在辊壳表面加热的丝束表面为M表面。第二对牵伸热辊1700采用可调角度热辊+可调角度热辊，热辊外壳表面为氧化铬+氧化铝，此辊为高温辊，对辊尺寸(2×φ(190-250)×(350-450)mm)。第一对牵伸热辊1600为低温辊，温度设定为75-100℃，第二对牵伸热辊1700为高温辊，温度设定为110-145℃，可以使丝束温度逐步稳定上升，有利于使纤维逐渐取向、结晶，以达到生物基聚酰胺产业用丝纤维的力学性能。放置第二加热板1520使每根丝单独从加热器间通过，并将在第二对牵伸热辊1700表面稳定铺开，提高了丝束的内外温度一致性，提高了丝束的受热均匀性，以利于后道加热、牵伸。从第一对牵伸热辊1600到第二对牵伸热辊1700，丝束受热面反过来了，此时丝束在辊壳表面加热的丝束表面为M表面。此过程丝束的M表面也受到了加热，再加上第二加热板1520的加热平衡，有利于提高纤维的结晶度和取向度，可以逐渐提高纤维的强度和模量。第二加热板1520设定温度95-115℃，丝束在经过第二加热板1520后传至第二对牵伸热辊1700。丝束在第二对牵伸热辊1700的辊面上顺时针的缠绕6.5圈～7.5圈，纺速1680m/min。第一对牵伸 热辊1600与第二对牵伸热辊1700牵伸倍数一般为1.5～3.5倍，这级牵伸是为了获得具有高取向、较低结晶度。纺55dtex-111dtex比纺1670dtex-2222dtex总纤度和单丝纤度都低，受热面积小，需要相对低5-10℃的加热环境，由于丝相对细，牵伸比小5％-10％。
在一些实施方式中，如图10至图12所示，丝束在第二对牵伸热辊1700上缠绕后，丝束被第三对牵伸热辊1800牵引，经过第三加热板1530对n根丝束的M、N两面均被加热。丝束在第三对牵伸热辊1800表面稳定铺开，丝束在第三对牵伸热辊1800的两辊辊面上缠绕6.5圈～7.5圈，n根丝束在辊壳表面均匀铺开，丝束在辊壳表面加热的丝束表面为N表面。从而这级牵伸可获得一定的强力和伸长，纺55dtex-111dtex比纺1670dtex-2222dtex总纤度和单丝纤度都低，受热面积小，需要相对低5-15℃的加热环境，由于丝相对细，牵伸比小4％-12％。第三加热板1530设定温度110-155℃，丝束在经过第三加热板1530后传至第三牵伸热辊，第三对牵伸热辊1800采用可调角度热辊+可调角度热辊，热辊外壳表面为氧化铬+氧化铝，对辊尺寸(2×φ(190-250)×(350-450)mm)，此辊为高温辊，丝束在第三对牵伸热辊1800的辊面上缠绕6.5圈～7.5圈，温度设定为130-150℃，在一些可实施方式中为140℃，纺速2520m/min，第二对牵伸热辊1700与第三对牵伸热辊1800牵伸倍数一般为2.0～3.5倍，形成二次加热和牵伸，进一步使丝束温度逐步稳定上升，提高纤维的均匀性和牵伸倍数，提高丝束强度。放置第三加热板1530使每根丝单独从加热器间通过，并将在第三对牵伸热辊1800表面稳定铺开，进一步提高了丝束的内外温度一致性，提高了丝束的受热均匀性，以利于后道加热、牵伸。从第二对牵伸热辊1700到第三对牵伸热辊1800，丝束受热面再次反过来了，此时丝束在辊壳表面加热的丝束表面为N表面。使丝束两面都受到加热，再加上第三加热板1530的加热平衡，有利于提高纤维的结晶度和取向度，可以逐渐提高纤维的强度和模量。
在一些实施方式中，如图13至图15所示，丝束在第三对牵伸热辊1800上缠绕后，丝束被第四对牵伸热辊1900牵引，经过第四加热板1540内n根丝束的M、N两面均被加热。丝束在第四对牵伸热辊1900表面稳定铺开，丝束在第四对牵伸热辊1900的两辊辊面上缠绕6.5圈～7.5圈，n根丝束在辊壳表面均匀铺开,此时丝束在辊壳表面加热的丝束表面为M表面。这级牵伸同样是为了获得一定的强力和伸长，具有一定的预定型作用。纺55dtex-111dtex比纺1670dtex-2222dtex总纤度和单丝纤度都低，受热面积小，需要相对低2-10℃的加热环境，由于丝相对细，牵伸比小2％-8％。第四加热板1540的设定温度为125-195℃，第三对牵伸热辊1800与第四对牵伸热辊1900之间形成第三次加热和牵伸，牵伸倍数一般为1.7～2.5倍，进一步使丝束温度逐步稳定上升，提高纤维的均匀性和牵伸倍数，提高丝束强度。放置第四加热板1540使每根丝单独从加热器间通过，并将在第四对牵伸热辊1900表面稳定铺开，进一步提高了丝束的内外温度一致性，提高了丝束的受热均匀性，以利于后道加热、牵伸。从第三对牵伸热辊1800到第四对牵伸热辊1900，丝束受热面再次反过来了，此时丝束在辊壳表面加热的丝束表面为M表面。使丝束两面都受到加热，再加上第四加热板1540的加热平衡，有利于后续牵伸中结晶区取向度和晶粒尺寸的增加和晶区的完善，丝束在经过第四加热板1540后传至第四对牵伸热辊1900，第四对牵伸热辊1900采用可调角度热辊配合可调角度热辊，热辊外壳表面为陶瓷，对辊尺寸(2 ×φ(190-235)×(350-400)mm)，此辊为高温辊，温度设定为130-150℃，丝束在第四对牵伸热辊1900的辊面上缠绕6.5圈～7.5圈，纺速3650m/min。
在一些实施方式中，如图16至图18所示，丝束在第四对牵伸热辊1900上缠绕后，丝束被第五对牵伸热辊2000牵引，经过第五加热板1550，第五加热板1550设定温度140-220℃，在第五加热板1550内，n根丝束的M、N两面均被加热。丝束在第五对牵伸热辊2000表面稳定铺开，丝束在第五对牵伸热辊2000的两辊辊面上缠绕6.5圈～7.5圈，n根丝束在辊壳表面均匀铺开，此时丝束在辊壳表面加热的丝束表面为M表面。这级起到松弛定型作用，纺55dtex-111dtex比纺1670dtex-2222dtex总纤度和单丝纤度都低，受热面积小，需要相对低1-4℃的加热环境，由于丝相对细，松弛比小1％-3％。第四对牵伸热辊1900与第五对牵伸热辊2000牵伸倍数一般为0.9-1.0倍，第五对牵伸热辊2000的速度略低于第四对牵伸热辊，二者之间纤维又有一定的回缩，完成高强丝的定型主要作用是对牵伸后的丝束进行定型，消除纤维因高速牵伸产生的应力。以便更好控制低收缩率。放置第五加热板1550使每根丝单独从加热器间通过，并将在第五对牵伸热辊2000表面稳定铺开，进一步提高了丝束的内外温度一致性，提高了丝束的受热均匀性，以利于后道定型回缩。丝束在经过第五加热板1550后传至第五对牵伸热辊2000，第五对牵伸热辊2000采用可调角度热辊+可调角度热辊，热辊外壳表面为陶瓷，对辊尺寸(2×φ(190-220)×(350-400)mm)，此辊为高温辊，丝束在第五对牵伸热辊2000的辊面上缠绕6.5圈～7.5圈，温度设定为130-210℃，纺速3550m/min。

其中，箱体管道430包括连通熔体管道300与可拆卸泵座483、以及连通可拆卸泵座483与纺丝组件600，配合计量泵500安装于可拆卸泵座483，熔体从熔体管道300沿一部分箱体管道430输送到可拆卸泵座483内，可拆卸泵座483内设有通道，并且该通道经过计量泵后又回到泵座内并从另一处开口，以将熔体沿另一部分箱体管道430输送到纺丝组件600内。
其中，计量泵500另与传动机构连接。
在一些实施方式中，纺丝箱400设有多个纺丝组件600，从可拆卸泵座483至每个 纺丝组件600分别有一部分箱体管道430，可设置该部分管道的长度一致，如通过图32中所示管道盘绕等设置，有利于熔体均匀分配。
本实施例中纺丝箱体400，设置成双层结构，包括相互固定的上箱体410和下箱体420，且相应设置元件，有利于减小体积，便于吊装、煅烧处理。在另一方面，纺丝箱体400呈体积较小的1位/箱结构设置，在由于生物基聚酰胺原料的不稳定性，经常会降解碳化，造成管路逐渐堵塞，需要拆解和煅烧时，通过小体积和上箱体410、下箱体420的双层结构设置，便于在普通煅烧炉中处理，从而避免了需要特殊大型的煅烧设备的不利情形。
其中，如图31所示，计量泵500处于上箱体410，纺丝组件600处于下箱体420，并且上箱体410、下箱体420采用不同的加热器进行加热，从而对上箱体410、下箱体420内的温度分开调节，尤其可控制下箱体420温度较高从而使纺丝组件600处于较高的温度，有利于纺丝组件600的喷丝板出丝，便于出丝速度和纺丝质量。
其中，通过计量泵500将熔体利用高压连续地准确地供给纺丝组件600用于纺丝。因为计量泵500要求有高精密的计量准确性，计量泵传动部件传动轴是由永磁同步电机直联摆线针齿减速器驱动、变频调速。每个计量泵传动电部件分别独立传动。传动轴可以伸缩，传动轴设有万向联轴节和安全销保护装置。保证熔体以相等的停留时间输送到每一个纺丝部位，依次进入纺丝组件600。

在一些实施方式中，单体抽吸机构800包括可以抽吸本体810、抽吸组件820和多 个整流加热板830，抽吸本体810设有导通至纺丝组件的喷丝板的本体通道811。抽吸组件820包括抽吸管道821、真空泵822、压缩空气管道823和加热线圈824，抽吸管道821与本体通道811连通，真空泵822设于抽吸管道821上。压缩空气管道823一端以通入压缩空气，另一端伸入抽吸管道821内、并且该另一端置于抽吸本体810与真空泵822之间。加热线圈824环绕抽吸管道821设置且设于抽吸本体810与压缩空气管道823之间。多个整流加热板830间隔布置于本体通道811，且于本体通道811中形成导通至抽吸管道821的整流通道。含单体的热蒸汽经整流通道被负压吸入到抽吸管道821内，并从抽吸管道821另一端排出
缓冷器700向纺丝组件600的喷丝板喷射过热蒸汽，在单体和低聚物于高温下随熔体从喷丝孔中逸出时，于喷丝板表面形成过热蒸汽保护层，过热蒸汽与单体漂浮物形成云状，从而避免附着在喷丝板表面，从而改善喷丝板被堵孔的不利情形。
含单体的热空气沿抽吸本体810的本体通道811从抽吸管道821被负压抽出，在一些实施方式中，压缩空气管道823向抽吸管道821通入压缩空气时，于抽吸管道821内形成负压区，在整流加热板830与抽吸本体810形成的若干整流通道的基础上，含单体的热空气沿整流通道被均匀地抽吸到抽吸管道821内，并且整流通道还有利于单体较快进入抽吸管道821，进一步通过真空泵822从抽吸管道821另一端排出。
