Knitted Fabric Connection Loops for Fray Prevention Without Stiffness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional knitted fabrics with thermal adhesive elastic fibers to prevent fraying result in a foreign body sensation and ring-shaped marks due to difficulty in stretching and potential fraying during wear.
Innovation Solution
A knitted fabric with an edge processing portion comprising connection loops knitted along a specific course to connect adjacent loops, preventing fraying without thermal adhesive fibers, thereby reducing the foreign body sensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermal adhesive elastic fibers are used to prevent fraying, then the end portion is prevented from fraying, but the fibers cure to be difficult to stretch causing foreign body sensation and ring-shaped marks
Solution Approach 1:
The patent removes thermal adhesive elastic fibers from the knitted fabric structure and replaces them with a mechanical edge processing portion consisting of connection loops. This extraction eliminates the harmful curing effect while maintaining fraying prevention through an alternative structural approach.
Solution Approach 2:
The patent replaces the thermal adhesive mechanism with a mechanical knitting-based connection system. The connection loops are knitted into the fabric structure itself, using mechanical interlocking rather than thermal bonding to prevent fraying, thereby eliminating the foreign body sensation associated with cured thermal adhesives.
2Reliability
If thermal adhesive elastic fibers are used to prevent fraying, then the end portion is prevented from fraying, but the fused fibers may fray due to friction during wearing
Solution Approach 1:
The connection loops are designed to be dynamically integrated into the knitted fabric structure, allowing the fabric to stretch and move naturally while maintaining the connection. This dynamic design prevents the rigid fused structure from fracturing under friction during wearing.
Solution Approach 2:
The edge processing portion is merged with the main knitted fabric body, with connection loops being knitted continuously along the course. This integration ensures that the fraying prevention mechanism moves with the fabric during wear, maintaining structural stability without creating rigid fused points.
3Reliability
If thermal adhesive elastic fibers are used to prevent fraying, then the end portion is prevented from fraying, but the fused fibers are difficult to stretch
Solution Approach 1:
The connection loops are positioned locally at the edge portion where fraying occurs, rather than fusing the entire fabric structure. This localized approach prevents fraying at the critical edge area while leaving the rest of the fabric freely stretchable, as the connection loops are knitted into the existing fabric structure rather than being fused on top of it.

AI summary
Provided is a knitted fabric having an end portion on a finishing side of knitting which is unlikely to fray and producing a reduced foreign body sensation when touched. The knitted fabric (100) includes: a knitted fabric body (101) having an opening end portion (102) at one end thereof on a finishing side of knitting; and an edge processing portion (W) including a plurality of connection loops (Wc) knitted along a specific course that is one course of a plurality of courses located on an opening end portion (102) side, the edge processing portion (W) connecting adjacent loops in the specific course to each other with use of a corresponding one of the connection loops (Wc).
