Solution Overview
Problem
Existing woven and knitted fabrics made of synthetic fibers fail to provide adequate fabric/skin separation and sweat oozing prevention, especially during exercise, and lack a natural-like surface feel.
Innovation Solution
Incorporating C-shaped cross-section fibers with specific surface roughness and elongation characteristics, combined with a water-absorbent resin, to create a fabric with enhanced fabric/skin separation and sweat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If flat yarns with flat shaped cross section are used to increase fiber surface area, then water absorbency and moisture transpiration are improved, but fabric/skin separation during exercise and sweat oozing prevention are not sufficiently effective
Solution Approach 1:
The invention applies local quality by creating specific surface roughness characteristics (Sq: 5-100 μm) in different regions of the fabric surface. The C-shaped cross-section fibers provide localized unevenness that creates air gaps between fabric and skin, improving fabric/skin separation while maintaining overall water absorbency through the increased surface area.
Solution Approach 2:
The C-shaped cross-section fibers introduce asymmetry in the fabric structure. The non-uniform surface feeling created by these asymmetric fibers generates micro-air layers between the fabric and skin, enhancing fabric/skin separation during exercise while the overall increased surface area maintains moisture management capabilities.
2Quantity of substance
If the fabric thickness is increased to improve water absorbency and reduce sweat oozing, then sweat absorption capacity is improved, but exercise comfortability and mobility are impaired
Solution Approach 1:
The invention utilizes porous materials by creating a fabric structure with controlled surface roughness (Sq: 5-100 μm) that forms micro-pores and air gaps. This porous structure increases water absorbency and sweat management capacity without requiring increased fabric thickness, thereby maintaining exercise comfortability and mobility.
3Stability of the object's composition
If synthetic fibers with uniform structure are used, then dynamic characteristics and dimensional stability are improved, but natural-like non-uniform unevenness feeling cannot be obtained
Solution Approach 1:
The invention applies local quality by introducing controlled surface roughness (Sq: 5-100 μm) and non-uniform characteristics at the fiber level using C-shaped cross-section fibers. This creates a natural-like unevenness feeling on the fabric surface while the overall synthetic fiber structure maintains dimensional stability and dynamic characteristics.

AI summary
To provide a woven/knitted fabric having excellent fabric/skin separation, a woven/knitted fabric is provided that includes C-shaped cross-section fibers, wherein an average standard deviation Sq of surface roughness of at least one surface of the woven/knitted fabric is 5 μm or more and 100 μm or less, and a ratio (Sqs/Sq) of an average standard deviation Sqs of surface roughness of the one surface when the woven/knitted fabric is elongated by 10% to the average standard deviation Sq, is 0.85 or more and 2.00 or less.
