Pilling is a common and unresolved problem in knitted fabrics, especially for the cellulose fiber blended fabrics, which not only causes an unattractive appearance and an uncomfortable handle, but also reduces the added value of the products. In this study, four different kinds of knitted fabrics were treated with 2,4,6-trichloropyrimidine (TLP) alkaline emulsion by dipping and pad–dry–cure modification processes. The surface morphology and chemical structure of original and treated fabrics were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The anti-pilling performance, thermal properties, physical and mechanical properties and color features of treated fabrics were also evaluated. The results indicated that TLP was successfully covalently crosslinked onto the surface of the cellulose fibers. The dipping process resulted in a better anti-pilling property than that of the pad–dry–cure process, and both treatments could bring about an excellent anti-pilling property and outstanding laundering durability. A pilling grade of 4.5 was achieved for the treated polyester/viscose (T/V) fabric with the dipping process even after 20 washing cycles. In addition, the treated fabrics displayed an enhanced antistatic property and still maintained a soft handle. Besides, the bursting strength and air permeability of treated samples were found to have a slight deterioration, while no apparent differences were found in the color parameters and colorfastness of dyed fabrics. The above results demonstrate that 2,4,6-trichloropyrimidine has the potential application prospect in the functional finishing and home-caring of textiles.

2,4,6-三氯嘧啶处理改善纤维素纤维混纺针织物的抗起球性能

起球是针织织物中普遍且尚未解决的问题，特别是对于纤维素纤维混纺织物而言，起球不仅导致外观不美观和手感不舒服，而且还降低了产品的附加值。在这项研究中，通过浸渍和干法-干法改性工艺，用2,4,6-三氯嘧啶（TLP）碱性乳液处理了四种不同的针织物。通过扫描电子显微镜（SEM），傅立叶变换红外光谱（FTIR）和X射线衍射（XRD）表征原始和处理过的织物的表面形态和化学结构。还评估了处理过的织物的抗起球性能，热性能，物理和机械性能以及颜色特征。结果表明，TLP成功地共价交联到纤维素纤维的表面上。浸渍过程比起干固化过程具有更好的抗起球性能，两种处理都可以带来出色的抗起球性能和出色的洗涤耐久性。处理后的聚酯/粘胶（T / V）织物即使经过20个洗涤循环，其起球等级仍达到4.5。另外，经处理的织物显示出增强的抗静电性能并且仍然保持柔软的手感。此外，发现经处理的样品的破裂强度和透气性略有劣化，而在染色织物的颜色参数和色牢度方面未发现明显差异。以上结果表明2,4，
