As a representative of dope‐dye, the color masterbatch method has been widely applied in modern dyeing processes, while it has difficulties in solving the dispersibility of inorganic pigments color master batch in the polymer matrix. In this work, attapulgite (ATP) was used as the adsorption carrier of inorganic pigments to prepare color‐dyed attapulgite (CD‐ATP). The selected environmentally friendly inorganic pigments were well adsorbed by ATP in KOH aqueous solution, and could stably be monodispersed in KOH aqueous solution for more than 168 h. Moreover, the KOH aqueous solution could be reused repeatedly, thereby, a sustainable method to prepare novel CD‐ATP was realized. By blending the as‐prepared CD‐ATP with polyamide‐6 (PA6), a series of dope‐dyed colorful PA6 composites was prepared. Scanning electron microscope (SEM) results indicated that the CD‐ATP was still monodispersed in the PA6 matrix, and endowed PA6 with a vivid color. Further studies show that the adding of CD‐ATP had little influence on the properties of PA6, but significantly reduced the water adsorption. This novel color‐dyed ATP has potential implications in making paper‐making blankets and is highly expected to have more extensive applications in many fields of life.

The facile characterization of isothermal microphase separation kinetics in polyamide 6 (PA6)‐based thermoplastic elastomers (TPAE‐6) has long posed a challenge for the development of suitable melt spinning processes. In this study, this challenge was addressed through Differential Scanning Calorimetry (DSC) measurements. It was assumed that the enthalpy changes of TPAE‐6 during the isothermal process are a linear superposition of enthalpy changes associated with microphase separation and crystallization of PA6 in hard phases, resembling that of TPAE‐6 without soft segments (TPAE‐6‐0). The study revealed that, as the concentration of soft segments in TPAE‐6 increases, the accelerated dynamics of phase separation become stronger than the dilution of soft segments to PA6 segments during isothermal process, resulting in an increase in the microphase separation rate of TPAE‐6. Furthermore, despite microphase separation, the overall crystallization rate of TPAE‐6 decreased with rising isothermal temperature and varied with increasing soft segment content at different temperatures. Additionally, the crystallization mode of TPAE‐6 followed two‐dimensional, three‐dimensional or a combination of both crystal growth mechanisms, accompanied by a heterogeneous nucleation mechanism.This article is protected by copyright.
