Benefits of technology

This patented technology allows for uniform distribution of fine-grained solid colored resin (pixels) on fiber surfaces without increasing their thickness or making them harder to break down when rubbed together during use. By adding small amounts of certain chemicals that interact strongly between these tiny solids, this process ensures stable dispersion over time while maintaining good print quality. Overall, this new technique improves durability and reliance on digital printers by allowing better control over how much each toner weigh per unit area used compared to traditional methods like ball mill pulverization.

Problems solved by technology

This patents discuss various aspects related to coatings for fabrics like clothing, paper, laminates, carpet tickets, rugs, etc., which require improved properties including better print quality, longer life span, less environmental pollution during manufacturing processes, durable bond between layers, low volatilization rates when stored at room temperatures, and proper hardening times. Additionally, these technologies aim to enhance image permanence and glossiness while maintaining other desired qualities such as moisturizing property, heat dissipativity, weldabilitancy, adherend ability, corrosion preventive effectiveness against metal flakes, lubricative effects, and compatibility with different types of liquid carriages.

Abstract

The invention discloses high-color-fastness water-based pigment black and a preparation method and application thereof. The preparation method comprises the steps: employing an auxiliary for grinding to obtain small-particle-size pigment, then an adhesive and a cross-linking agent are added to form wrapped pigment, performing further grinding, achieving the technical effect that the particle size is smaller than 100 nm, and obtaining the pigment liquid with the small particle size for the first time, so the organic pigment particle fixation effect of the binder/cross-linking agent can be maximized, and after the ink is diluted into the ink-jet ink, the binding strength of the organic pigment particles on the fiber is improved, and the excellent color fastness can be obtained.
