Solution Overview
Problem
Conventional fabric coatings fail to meet the performance requirements of high-end applications such as high-strength, waterproof-and-moisture-permeability, and durability for materials like high-end tents, toys, and travel bags, due to their low strength and limited functional attributes.
Innovation Solution
A multifunctional high-strength composite fabric coating agent comprising a resin, a reinforcing agent with reactive groups, a bifunctional dispersing agent, a leveling agent, a film-forming agent, a softening agent, an antibacterial agent, and a solvent, which enhances binding force, penetrates fabric effectively, and provides excellent durability and adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional fabric coating is applied, then the fabric gains basic functional attributes, but the strength and durability do not meet high-end application requirements
Solution Approach 1:
The patent uses a composite coating formulation combining multiple polymers (polyvinyl chloride resin, polyurethane resin, and acrylic resin) with specific functional additives. This composite approach creates a coating that simultaneously achieves high tensile breaking strength (≥80 N), excellent tearing resistance, and superior durability for high-end applications like tents and travel bags.
2Strength
If coating is applied to improve strength, then the fabric strength increases, but the softness and air permeability may be compromised
Solution Approach 1:
The patent applies local quality by using a multi-component coating system where each polymer contributes specific properties: polyvinyl chloride provides strength, polyurethane maintains softness and flexibility, and acrylic ensures air permeability. The coating thickness is controlled at 5-15 μm to provide reinforcement while preserving the fabric's inherent softness and breathability characteristics.
3Adaptability or versatility
If functional additives are incorporated to enhance performance, then the coating provides multiple functions, but the manufacturing complexity increases
Solution Approach 1:
The patent incorporates multiple functional additives into a single universal coating formulation: antibacterial agents (silver ions, zinc oxide) for hygiene, UV absorbers for sun protection, waterproofing agents for moisture resistance, and flame retardants for safety. This multi-functional coating can be applied to various fabric types for different applications without requiring separate formulations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The coating significantly improves tensile breaking strength, tearing resistance, and bursting resistance while maintaining softness and air permeability, with high adhesion and antibacterial properties, suitable for various materials and scalable production.
Implementation Method 1
A reinforcing agent in a multifunctional high-strength composite fabric coating agent provided by the present invention has reactive groups resulted from a surface modification treatment to the reinforcing agent, such as —OH, —NH3 or the like, which enhances the binding force between the coating and the fabric
Implementation Method 2
A bifunctional dispersing agent in the multifunctional high-strength composite fabric coating agent provided by the present invention not only provides a dispersing function but also the function of reducing surface tension of the coating, such that the multifunctional high-strength composite fabric coating can more effectively penetrate in between yarns and into micropores of fibers

AI summary
A multifunctional high-strength composite fabric coating agent, a coating, a method for preparing the same and an application thereof are provided. The fabric coating agent includes a resin, a reinforcing agent with a reactive group, a bifunctional dispersing agent, a leveling agent, a film forming agent, a softening agent, an antibacterial agent, a solvent, and the like. The reinforcing agent is modified such that it has active functional groups of —OH and NH3. The fabric coating agent is not only easy to apply, fast to react and stabilize, but also suitable for a fabric surface of any material. A treated fabric has high tensile-breaking strength, excellent tearing and bursting performance, good waterproof-and-moisture-permeability and antibacterial performance, and high adhesion. It can be repeatedly knife coated, roll coated, calendared, or dipped. The method is not only mature in technology and low in production cost, but also suitable for large-scale application.
