Terry Fabric With Differential-Height Synthetic Filament Piles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terry fabrics face challenges in optimizing fabric structure for end-use requirements, particularly in achieving improved cushion and unique visual features, which is not always predictable.
Innovation Solution
A terry article is designed with a ground component and pile components on both sides, featuring natural fiber piles and continuous filament thermoplastic yarns, where the latter undergoes shrinkage treatment to create a pile height differential, enhancing cushion and visual texture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If uniform pile height is used throughout the terry fabric, then manufacturing simplicity is maintained, but cushion profile and visual texture are insufficient
Solution Approach 1:
The patent applies local quality by creating different pile heights in specific regions of the fabric. The first plurality of piles has a first height while the second plurality of piles has a second height different from the first, creating localized variations in cushion profile and visual texture rather than uniform characteristics throughout the entire fabric surface.
Solution Approach 2:
The patent segments the pile component into distinct groups with different heights. The pile component includes a first plurality of piles and a second plurality of piles, where each plurality has different height characteristics, dividing the originally uniform structure into segmented zones with differentiated functions for cushioning and visual appeal.
2Shape
If single fiber type is used for all piles, then manufacturing process is simplified, but visual texture and aesthetic appeal are reduced
Solution Approach 1:
The patent uses composite materials by incorporating two different fiber types in the pile component. The first plurality of piles is formed from a first fiber type while the second plurality of piles is formed from a second fiber type different from the first, creating visual texture variations and aesthetic appeal through material diversity rather than uniform fiber composition.
Solution Approach 2:
The patent applies local quality by assigning different fiber types to different regions of the pile component. Specific areas contain piles made from the first fiber type while other areas contain piles made from the second fiber type, creating localized variations in visual texture and tactile properties throughout the fabric surface.
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 design achieves improved cushion profiles and visually observable textures by creating pile height differentials, making the terry articles suitable for various applications from home to industrial uses.
Implementation Method 1
The second plurality of piles are formed from a set of continuous filament thermoplastic yarns and define a second pile height that is less than the first pile height

AI summary
A terry article includes a ground component including a plurality of ground warp yarns and a plurality of weft yarns, and a pile component disposed on at least one of a lower side and an upper side of the ground component. The pile component includes a first plurality of piles that extend away from the ground component along a vertical direction. The first plurality of piles are formed from a first set of pile yarns comprised of natural fibers and further define a first pile height. The pile component also includes a second plurality of piles that extend away from the ground component in the vertical direction. The second plurality of piles are formed from a set of continuous filament thermoplastic yarns and define a second pile height that is less than the first pile height.
