Acrylic Coating for Cold Transfer Printing Paper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transfer printing methods fail to effectively transfer patterns onto natural fibers like cotton and wool due to ink adhesion to the paper, resulting in low transfer rates, environmental pollution, and waste, while existing solutions lack the necessary hydrotropic and peeling rates for efficient dye transfer.
Innovation Solution
A connecting material for cold transfer printing paper comprising an acrylic coating agent composition with both an isolating layer and an ink-receiving layer, where the isolating layer includes acrylic resin, solvent, toughening agent, and filler, and the ink-receiving layer comprises acrylic monomer, modified starch, emulsifier, surfactant, initiator, and crosslinking agent, enhancing ink retention on the paper and facilitating high transfer rates to fabrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional transfer printing paper is used for natural fibers, then water-soluble dyes can be applied, but the ink adhesion to paper causes low transfer rate (about 60%)
Solution Approach 1:
The connecting material is divided into two functional layers: an isolating layer that prevents ink penetration into the base paper, and an ink-receiving layer that facilitates ink transfer to fabric. This segmentation resolves the contradiction by allowing water-soluble dyes to be used on natural fibers while achieving high transfer rates through the coordinated action of both layers
Solution Approach 2:
The connecting material acts as an intermediary substance between the base paper and the printing ink. It provides a controlled interface that allows ink to be retained during printing but easily transferred during the transfer process, enabling high transfer rates for water-soluble dyes on natural fibers
2Ease of manufacture
If conventional transfer printing methods are used, then printing can be performed, but a large amount of dye remains on the printing paper causing environmental pollution and low regeneration rate
Solution Approach 1:
The isolating layer, which initially might seem to trap ink and cause pollution, is designed to work in conjunction with the ink-receiving layer to enable complete ink transfer. The layering structure converts the potential harm of ink retention into the benefit of controlled ink release, achieving over 90% transfer rate and reducing environmental pollution
3Device complexity
If a single-layer connecting material is used, then the structure is simple, but it cannot simultaneously provide ink retention and easy transfer
Solution Approach 1:
The connecting material is segmented into two distinct layers with specific functions: the isolating layer (comprising acrylic resin, solvent, toughening agent, and filler) prevents ink penetration, while the ink-receiving layer (comprising acrylic monomer, modified starch, emulsifier, surfactant, initiator, and crosslinking agent) enables ink transfer. This segmentation achieves high transfer rates while maintaining operational simplicity
4Strength
If the isolating layer is too strong, then ink penetration is prevented, but ink transfer to fabric becomes difficult
Solution Approach 1:
The isolating layer is designed with appropriate strength to prevent ink penetration into the base paper, while the ink-receiving layer provides a controlled interface for ink transfer. The two-layer structure ensures that the isolating layer's barrier property does not hinder the transfer function, achieving both ink retention and high transfer rate
Solution Approach 2:
Different regions of the connecting material have different properties: the isolating layer has strong barrier properties to prevent penetration, while the ink-receiving layer has controlled affinity properties to facilitate transfer. This local quality differentiation resolves the contradiction between strength and transferability
