Hosiery Toe Closing Method with Interlaced Tail Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toe closing methods for hosiery items result in loose threads that can cause discomfort and lead to defective products if too long or too short, affecting wearability and product integrity.
Innovation Solution
A toe closing method and structure that involves folding circumferential portions of the hosiery body to align loops, knitting a stitching thread to form initial and joining segments, and creating tail portions to secure loose threads, ensuring they are interlaced with the hosiery loops, thereby fixing the threads in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional toe closing apparatus is used to close the toe end of a hosiery body, then the toe end can be closed, but loose threads are formed on two opposite sides of the toe end which can cause discomfort to the wearer
Solution Approach 1:
The stitching process is divided into multiple segments: initial stitch segment, joining segment with first and second sections, and tail portion. Each segment serves a specific function in managing the stitching thread, with the tail portion specifically designed to secure and conceal the end of the thread, preventing loose threads from forming on the hosiery surface
Solution Approach 2:
The tail portion acts as an intermediary element between the joining segment and the hosiery loops. It provides a transition zone where the stitching thread is gradually incorporated into the hosiery structure through interlacing, preventing the thread end from protruding as a loose thread while maintaining structural integrity
2Object-affected harmful factors
If the loose threads are cut too short to avoid discomfort, then comfort is improved, but the stitches may become loose causing damage to the toe end
Solution Approach 1:
The tail portion is formed in advance during the toe closing process, creating a secure anchor structure before the stitching is completed. This preliminary structure ensures that when the stitching thread is trimmed, the stitches remain secure because the tail portion has already interlaced the thread end with the hosiery loops, distributing the stress and preventing stitch loosening
Solution Approach 2:
The tail portion extends the stitching thread into a third dimensional space by creating loops that interlace with multiple rows of hosiery loops. This multi-dimensional interlacing structure provides redundancy and security, allowing the thread to be trimmed short without compromising stitch integrity, as the tail portion distributes the load across multiple attachment points
3Reliability
If the stitching thread is knitted continuously around the superimposed circumferential portions, then the toe end is securely closed, but the process becomes complex
Solution Approach 1:
The continuous stitching process is segmented into distinct phases (initial stitch segment, joining segment with first and second sections, and tail portion), where each phase has a specific function. This segmentation allows for systematic control of the stitching thread path, ensuring secure closure while maintaining process clarity and manageability through defined stages
Solution Approach 2:
The stitching process employs dynamic adjustments in the knitting machine's needle selection and thread tension control to accommodate the different segments. The machine dynamically switches between stitching the initial segment, the joining segment with its two sections, and the tail portion, with each phase having optimized parameters for security and simplicity

AI summary
A toe closing method for closing a toe end (110) with first and second circumferential portions (10, 20) includes the steps of: folding the first circumferential portion (10) to superimpose over the second circumferential portion (20) such that the toe end (110) is formed with opposed first and second end points (130, 140); knitting a stitching thread (T) by threading the same through the loops (120) of the superimposed circumferential portions (10, 20) to form a first loose thread (31) and an initial stitch segment (30); continuously knitting the thread (T) around the superimposed circumferential portions (10, 20) until the second end point (140) is reached to form a joining segment (40) ; and continuously knitting the thread (T) around a part of the joining segment (40) to form at least one tail portion (51, 52) and a second loose thread (53).
