1. Definition and Process Deep Dive●Solution Dyeing Principle: Dyes are dispersed and dissolved at the molecular level in polyester chips (PET) before melting, forming a homogeneous dye solution. During the spinning process, the dye migrates with the polyester melt into the spinneret, and colors are embedded within the fiber structure as it cools and solidifies, creating a permanent color matrix.●Comparison with Conventional Dyeing: Traditional dyeing methods (e.g., immersion or pad dyeing) ar

1. Definition Process●Solution Dyeing involves dissolving pigments directly into the polyester melt or solution during the fiber spinning process, enabling colors to be evenly distributed within the fiber core rather than surface application in traditional dyeing methods.●This technique integrates coloring at the fiber formation stage, eliminating post-dyeing steps and achieving permanent color fixation through internal penetration.2. Key Advantages●High Color Fastness: Resistant to washing,

Solution Dyed Acrylic Fabric: A Deep Dive into Technology, Sustainability, and InnovationsDefinition and Production ProcessSolution dyed acrylic fabric is a synthetic textile crafted through a unique coloring technique. Acrylic fibers, derived from polymers like polyacrylonitrile, are colored during the spinning stage rather than post-production. Pigments or dyes are dissolved into the polymer solution prior to fiber extrusion, resulting in a homogenous distribution of color molecules within the

Solution Dyed Acrylic Fabric: A Comprehensive Exploration of Technology, Performance, and Future ProspectsIn-Depth Production Process1.Polymer Preparation: Polyacrylonitrile (PAN) pellets are dissolved in a solvent (e.g., dimethylformamide) at temperatures between 80-120°C to form a viscous spinning solution.2.Dye Integration: Pigments (e.g., disperse dyes for bright colors or reactive dyes for deep shades) are added to the polymer matrix under controlled pH conditions (pH 4-6) to ensure homoge

Colors integrated into acrylic fibers during manufacturing for lasting vibrancy and resistance to fading, washing, sunlight, and chemicals.●Advantages: fade-resistant colors, soft texture, lightweight, eco-friendly (minimizes dye waste).-广泛应用于服装、家居用品及工业过滤等领域。●护理：可机洗，按标签指示处理。核心特点: 长效色彩、舒适耐用、多领域适用且环保。
