Carding Machine Component Load Schedule for Gradient Yarn Properties
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional yarn manufacturing methods result in uniform properties throughout the length of the yarn, making it difficult to change fabric properties without introducing visible changes like texture, color, or pattern, and the use of synthetic materials can leave undesirable residues after weaving.
Innovation Solution
A method of loading a carding machine with a component load schedule comprising discrete loading steps, using a blend of natural and sacrificial fibre materials, allowing for varying load amounts and types to create consistent or gradient properties in the yarn, which can be later processed to remove synthetic materials for lighter-weight fabrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional yarn manufacturing methods are used to maintain uniform properties throughout the yarn length, then the fabric has consistent appearance and properties, but it becomes difficult to change fabric properties without introducing visible changes like texture, color, or pattern
Solution Approach 1:
The patent applies local quality by varying the component load amounts at different discrete loading steps along the yarn length. Different sections of the yarn contain different proportions of components (e.g., natural fibers and synthetic materials), enabling localized property changes without visible transitions. This allows fabric properties to be changed in specific regions while maintaining overall uniformity.
Solution Approach 2:
The yarn manufacturing process is segmented into multiple discrete loading steps, where each step loads specific amounts of different components. This segmentation enables precise control over the composition at different yarn sections, allowing property changes to be implemented in a controlled manner without creating visible disruptions in the fabric.
2Strength
If synthetic materials are added to improve yarn strength and reduce breakage during weaving, then the yarn becomes stronger and more durable, but undesirable residues remain after the weaving process
Solution Approach 1:
The patent uses parameter changes by selecting synthetic materials with specific properties (water-solubility) that allow them to be removed after serving their purpose. The synthetic materials are chosen based on parameters like solubility in water or specific chemicals, enabling their complete removal after weaving without leaving residues, while maintaining yarn strength during the weaving process.
Solution Approach 2:
The synthetic materials serve as temporary support structures during weaving and are then completely removed (discarded) after the weaving process. This is achieved by using water-soluble or chemically removable synthetic materials that dissolve or decompose completely, leaving no residues in the final fabric product.
3Quantity of substance
If synthetic materials are used to support the yarn structure, then finer and lighter-weight fabrics can be manufactured, but the synthetic materials must be completely removed to avoid residues
Solution Approach 1:
The patent changes the chemical parameters of the synthetic materials by selecting materials with specific solubility characteristics. These materials are chosen to be completely soluble in water or specific chemicals, ensuring that when removed after weaving, they leave no residues. This enables the use of synthetic materials for structural support while achieving complete removal to produce lighter-weight fabrics without harmful residues.

AI summary
A method of loading a carding machine for the manufacture of yarn. The method includes deriving a component load schedule with a plurality of discrete loading steps. The series of discrete loading steps comprise at least a first load amount and a second load amount, wherein the sum of the first load amount and the second load amount is a first overall load amount. The method includes loading a first amount of a first component equal to the first load amount of a discrete loading step, loading a second amount of a second component equal to the second load amount of the discrete loading step and repeating the steps of loading a first amount and loading a second amount for each of the discrete loading steps.
