技术领域technical field
本发明属于涡流纺纺纱技术领域，具体涉及一种涡流混纺纱及其生产工艺。The invention belongs to the technical field of vortex spinning, and in particular relates to a vortex blended yarn and a production process thereof.
背景技术Background technique
涡流混纺纱是利用涡流纺的方式，通过高压气流加捻将几种不同的功能纤维混合包覆成纱，通过这种方式得到的纱线蓬松性好、耐洗涤、爽感性好、易上色。The eddy current blended yarn is the use of eddy current spinning. Several different functional fibers are mixed and wrapped into the yarn through high-pressure air twisting. The yarn obtained by this method has good fluffiness, washing resistance, good refreshment, and easy to put on. color.
涡流纺由于纺纱成纱方式的限制，目前能够生产的纱线细度在 10s-60s之间。在涡流纺过程中，纱线容易出现弱捻现象(即须条纤维含量太高，加捻不充分)，导致纱线品质低。如果采用较细的涤纶纤维生产粗支纱，由于气流作用力有限，纤维越细，越容易被分散开，从而在涡流纺内部形成有效的旋转和加捻，这样虽然能够在一定程度上避免弱环产生，但却会影响涡流纺纱线的蓬松性和手感。Due to the limitation of the spinning method, the fineness of the yarn that can be produced by vortex spinning is currently between 10s and 60s. In the process of vortex spinning, the yarn is prone to weak twist (that is, the fiber content of the whisker is too high and the twist is insufficient), resulting in low yarn quality. If finer polyester fibers are used to produce coarse count yarns, due to the limited airflow force, the thinner the fibers are, the easier they are to be dispersed, thus forming effective rotation and twisting inside the vortex spinning, which can avoid weak and weak yarns to a certain extent. Rings are created, but they affect the bulk and feel of the vortex spun yarn.
