System for injecting functional solution for fabric
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for imparting insulation, waterproofing, antifouling, antibacterial, and flame retardant properties to fabrics are inefficient, requiring lengthy processing times and prone to functional solution separation during friction or washing due to surface absorption rather than deep penetration.
Innovation Solution
A fabric injection system using a needle to directly inject a functional solution into the fabric, comprising a mixture of aerogel powder, solvents, and additives, with a reciprocating needle mechanism for quick and continuous injection, ensuring deep penetration and retention within the fabric.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blade is used to permeate a mixture into fabric, then the fabric can be treated with functional solution, but the permeation process takes a long time and processing efficiency is low
Solution Approach 1:
The patent replaces the mechanical blade permeation system with an injection needle system that delivers functional solution directly into the fabric interior through injection holes. This substitution of the delivery mechanism enables rapid injection and penetration without the slow blade-based permeation process, thereby improving processing speed while ensuring deep penetration of the functional solution into the fabric.
2Reliability
If a functional solution is applied from the outer surface of the fabric, then the fabric can be treated, but the solution cannot penetrate deeply and is easily separated by friction or washing
Solution Approach 1:
The patent inverts the conventional approach of applying functional solution from the outer surface by instead injecting the solution directly into the interior of the fabric through injection holes formed by the needle. This inversion of the delivery direction ensures deep penetration and anchors the functional solution within the fabric structure, preventing separation by friction or washing and thereby improving durability.
3Reliability
If a blade permeation method is used, then functional properties can be imparted to fabric, but the overall process time is lengthy
Solution Approach 1:
The patent replaces the time-consuming blade permeation mechanism with a rapid injection needle system that delivers functional solution directly into the fabric. This substitution eliminates the lengthy permeation process while maintaining functional properties retention, as the injection method ensures proper penetration and distribution of the functional solution within the fabric interior.

AI summary
The present invention relates to a system for injecting a functional solution for fabric and a method for manufacturing fabric using same. The system includes: a first supply portion; a second supply portion provided with a distributing device; an injection portion provided with a needle; a drying portion provided with a hot air blower or a blower; and a collection portion provided with a collecting roll. An injection method is provided in which the needle on the injection portion, installed so as to be moved reciprocally, is directly inserted into the fabric to inject the functional solution, so that the functional solution is absorbed from the outer surface to the inside of the fabric.
