Resin for use in setting a crease in a garment, a method and apparatus for applying the same and a garment including the resin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional resins used to set creases in garments contain tin or organo-tin components, which pose health risks and are increasingly resisted by legislators and users due to potential carcinogenic effects, necessitating a tin-free alternative that maintains crease retention and appearance without visibility or displacement.
Innovation Solution
A tin and organo-tin free resin system utilizing catalysts like platinum, peroxide, organic amine, titanium, zirconium, or organosilane to cure and harden on the garment's fabric, ensuring extended crease retention and invisibility, with a non-slump to flowable characteristic for effective bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional resin containing tin or organo-tin components is used to set creases in garments, then crease retention and rigidity are improved, but health risks and environmental harm increase due to potential carcinogenic effects
Solution Approach 1:
The patent removes the harmful tin or organo-tin curing components from the resin formulation while maintaining the essential crease-setting function through alternative catalysts such as platinum, peroxide, organic amine, titanium, zirconium, or organosilane
Solution Approach 2:
The patent changes the chemical composition parameters of the resin by substituting tin-based catalysts with alternative catalyst systems, thereby eliminating the harmful effects while preserving the curing and hardening capabilities necessary for crease retention
2Strength
If resin is applied as a large area surface coating to provide strength and rigidity, then crease retention is improved, but flexibility and comfort of the garment are restricted
Solution Approach 1:
The patent applies resin in the form of narrow lines or ribbons precisely at the crease locations rather than as a large area surface coating, providing localized strength and rigidity only where needed to maintain creases while preserving the flexibility and comfort of the rest of the garment
Solution Approach 2:
The patent divides the resin application into discrete narrow lines or ribbons along the crease paths, rather than applying a continuous broad coating, thereby concentrating the structural reinforcement function at specific locations
3Duration of action of stationary object
If resin cures and hardens quickly upon exposure to atmospheric conditions, then crease retention is improved, but the resin may become visible externally or displace from the crease line
Solution Approach 1:
The patent applies the resin in a fluid state to the crease line first, allowing it to properly position itself at the base of the V-shaped crease, and then the resin cures and hardens in place, ensuring accurate positioning while achieving the desired crease retention
Solution Approach 2:
The patent utilizes catalysts that control the curing rate and hardening characteristics of the resin, allowing sufficient time for the resin to set in the correct position while still achieving adequate crease retention, thereby preventing displacement or cracking
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 resin system effectively maintains crease lines for an extended period without health risks, ensuring the resin's safety and environmental friendliness while maintaining the garment's appearance and preventing displacement or cracking.
Implementation Method 1
said resin includes a catalyst to assist in the curing of the resin, said catalyst including any, or any combination of platinum, peroxide, Organic amine, titanium, zirconium, tertiary amine, organosilane, iron, copper and/or a non-metal

AI summary
A resin for use in setting a crease in a garment, a method and apparatus for applying the resin and a garment including the resin. The resin typically includes a silicone and a catalyst for commencing curing of the resin when the resin is exposed to moisture in ambient environmental conditions once applied onto a base of the crease line of the garment as a ribbon or line of resin. The resin is tin free and in one embodiment has characteristics of being non-slump initially and then changing to a flowable or self-levelling characteristic once applied to the crease line so as to absorb into and bond with fibres of a fabric from which the garment is formed before fully hardening.
