AI Technical Summary

Technical Problem

When the winding density of traditional pure cotton fabrics is high, the dye and auxiliaries have difficulty penetrating into the inner layer of the yarn, resulting in unevenness of excess outer auxiliaries and non-functional inner layers. In addition, the moisture-wicking and quick-drying functions of existing technologies have poor washability, which affects wearing comfort.

Method used

It adopts an adjustable winding rod and an internal dyeing structure that sprays from the inside out, combined with a closed dyeing chamber, to uniformly dye the yarn through the dyeing device. It also uses an environmentally friendly, formaldehyde-free functional finishing formula, along with pretreatment and dyeing processes, to ensure uniform distribution of dye liquor and auxiliaries.

Benefits of technology

It solves the problem of unevenness between the inner and outer layers of the yarn, improves the stability of moisture absorption and quick-drying function and water resistance, reduces production costs and environmental pollution risks, and improves the hand feel of the fabric and production efficiency.

Abstract

本发明涉及纺织染整技术领域，具体为一种环保型吸湿速干纯棉织物的染整加工工艺，包括浸染安装支架、活动设置于浸染安装支架底部两侧的活动侧安装架、设置于两个活动侧安装架相对一侧的筒子架、转动设置于两个筒子架之间的转动内筒和位于转动内筒外侧活动设置的若干个卷绕杆。本发明通过可调节位置的卷绕杆与自内向外喷射的内浸染结构相配合，能够在浸染过程中使纱线绕卷层形成均匀的渗透孔隙，染液和功能助剂可以从纱线内层向外层均匀扩散，解决了传统筒子染色中内层渗透困难、外层助剂过剩的不均匀问题，避免假性吸湿速干现象的发生；配合封闭浸染腔体能够减少染液的挥发损耗，同时便于染液的集中回收和循环利用。
