(1)本实施方式的处理剂含有选自矿物油、硅油和酯油中的至少1种平滑剂(A)、以及选自松香、松香衍生物、萜烯树脂和萜烯树脂衍生物中的至少1种天然来源成分(B)。因此,能够提高将被赋予了处理剂的弹性纤维特别是利用卷线机卷绕时的处理剂的飞散抑制效果。另外,能够提高被赋予了处理剂的弹性纤维的形状特性、特别是卷绕成筒纱形状时的形状特性。另外,还能够提高被赋予了处理剂的弹性纤维的防跳纱性。
需要说明的是,上述实施方式也可以如下进行变更。上述实施方式和以下的变更例能够在技术上不矛盾的范围内相互组合来实施。
·上述实施方式的处理剂中,在不妨碍本发明的效果的范围内,可以进一步混配用于保持处理剂的品质的稳定化剂、电荷控制剂、增粘剂、抗氧化剂、紫外线吸收剂等通常被用于处理剂中的成分。

试验分类2(弹性纤维的制造)
使由分子量1000的聚四亚甲基二醇和二苯基甲烷二异氰酸酯得到的预聚物在二甲基甲酰胺溶液中通过乙二胺进行扩链反应,得到浓度30%的纺丝原液。将该纺丝原液在加热气体流中由喷丝头进行干式纺丝。对于经干式纺丝得到的聚氨酯系弹性纤维,将试验分类1中制备的处理剂通过辊式涂油法进行纯给油。接着将被赋予了处理剂的聚氨酯系弹性纤维卷绕成卷装体,得到20旦尼尔(单丝)的处理后的聚氨酯系弹性纤维。关于处理剂的附着量的调节,按照通过调整给油辊的转速而使其均为5%的方式来进行。
使用这样得到的弹性纤维、进行了辊给油的干式纺丝聚氨酯系弹性纤维的卷装体,如以下所说明对飞散抑制效果、弹性纤维的形状特性、防跳纱性进行评价。
试验分类3(弹性纤维的评价)
·飞散抑制效果
将所得到的刚纺丝后的干式纺丝聚氨酯系弹性纤维卷装体(500g卷)以送出速度100m/分钟、卷绕速度250m/分钟卷绕30分钟,在这种情况下,通过目视观察在卷线机附近确认到的处理剂的飞散量。在卷线机下方铺上厚纸,观察附着于厚纸的处理剂,由此进行飞散量的观察。按以下的基准进行评价,将结果示于表1的“飞散”栏中。
◎(良好):未确认到飞散的情况
〇(合格):稍微确认到飞散的情况
×(不良):确认到相当量的飞散的情况
·形状特性的评价
在20旦尼尔(单丝)的聚氨酯系弹性纤维上通过辊给油法附着5.0%的试验分类1中制备的处理剂。之后藉由赋予卷宽42mm的横动导纱器使用表面带动卷纱法的卷绕机以550m/分钟的卷绕速度在长度57mm的圆筒状纸管上卷绕500g,得到聚氨酯系弹性纤维的卷装体。
对于所得到的聚氨酯系弹性纤维卷装体(500g卷),测量卷宽的最大值(Wmax)和最小宽度(Wmin),根据二者之差(Wmax-Wmin)求出膨胀量,按下述基准进行评价。将其结果示于表1的“形状”栏中。
◎(良好):膨胀量小于3mm的情况
○(合格):膨胀量为3mm以上且小于6mm的情况
×(不合格):膨胀量为6mm以上的情况
·防跳纱性的评价
对于所得到的刚纺丝后的干式纺丝聚氨酯系弹性纤维卷装体(500g卷),以送出速度20m/分钟、卷绕速度40m/分钟卷绕1000m,在这种情况下,按下述基准对于卷装体因跳纱所致的断纱的次数进行评价。将其结果示于表1的“防跳纱性”栏中。
◎(良好):因跳纱所致的断纱为0次的情况
○(合格):因跳纱所致的断纱为1次以上且小于3次的情况
×(不良):因跳纱所致的断纱为3次以上的情况
由表1的各实施例相对于各比较例的评价结果也可知,根据本发明的处理剂,能够抑制处理剂从被赋予了处理剂的弹性纤维的飞散。另外,能够提高形状特性和防跳纱性。
