Solution Overview
Problem
Conventional towels with non-twisted yarn piles are bulky, making them difficult to sew into clothing, while maintaining desirable properties like soft touch, lightness, and heat retention, which are not suitable for clothing that requires close skin contact.
Innovation Solution
A towel product with a pile formed of non-twisted yarn having a fine count of 6.56-11.81 tex, adjusted fiber length, and controlled reverse twisting to enhance touch feeling, lightness, breathability, and prevent fluff come-out, allowing easier sewing and maintaining heat retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a non-twisted yarn with conventional count (16-30 tex) is used for the pile, then the towel has soft touch feeling, lightness, and heat-retaining property, but the towel becomes bulky and difficult to sew into clothing
Solution Approach 1:
The patent applies parameter changes by reducing the yarn count from the conventional 16-30 tex range to a finer 6.56-11.81 tex range. This parameter change directly reduces the bulkiness and thickness of the towel fabric while maintaining the non-twisted yarn structure that provides soft touch feeling. The finer yarn allows the fabric to be thinner and more manageable for sewing operations, thus resolving the contradiction between sewing ease and bulkiness.
2Volume of moving object
If a non-twisted yarn with fine count (6.56-11.81 tex) is used for the pile, then sewing becomes easier and bulkiness is reduced, but the structure becomes weaker and more prone to fluff come-out
Solution Approach 1:
The patent applies composite materials by combining fine non-twisted yarn (6.56-11.81 tex) with a specific fiber composition consisting of 80-95% cotton fibers and 5-20% synthetic fibers. The synthetic fiber component (such as polyester or polyacrylic) acts as a reinforcing element that compensates for the reduced strength of the fine yarn. This composite structure maintains yarn integrity and suppresses fluff come-out while preserving the soft touch and breathability characteristics of the fine non-twisted yarn.
Solution Approach 2:
The patent applies local quality by differentiating the properties of different components within the yarn structure. The cotton fibers (80-95%) provide the soft touch feeling and breathability, while the synthetic fibers (5-20%) localized within the yarn structure provide tensile strength and structural integrity. This local differentiation of material properties allows the fine yarn to maintain both softness and strength simultaneously.
3Quantity of substance
If conventional non-twisted yarn is used for towel, then water absorbency is high, but breathability and touch feeling are insufficient for clothing applications
Solution Approach 1:
The patent applies parameter changes by using a finer yarn count (6.56-11.81 tex) which creates a different fiber arrangement and gap structure compared to conventional yarns. This parameter change enhances breathability by creating more numerous and finer air channels within the fabric structure. Simultaneously, the finer yarn provides a softer touch feeling suitable for clothing, while the high cotton content (80-95%) maintains excellent water absorbency properties.
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 solution improves touch feeling, lightness, breathability, and sewing ease while suppressing fluff come-out, ensuring the towel's properties are suitable for clothing applications without compromising heat retention.
Implementation Method 1
the towel having a pile formed of a non-twisted yarn, that traps water in a gap between fibers, is characterized by a high water absorbency property
Implementation Method 2
a pile formed of a non-twisted yarn is fluffily inflated and retains a large amount of air between fibers. Accordingly, a towel having a pile formed of a non-twisted yarn is characterized by soft touch feeling and lightness property for its bulky appearance... the towel having a pile formed of a non-twisted yarn is characterized by high heat-retaining property

AI summary
To provide a towel product having a pile formed of a non-twisted yarn, wherein good touch feeling, lightness, and breathability are improved and sewing thereof can be eased. A non-twisted yarn having a fine count (a yarn count of 40-90) is employed as a pile yarn, as compared to the conventional art. This contributes to enhancement of good touch feeling, lightness, and breathability and suppression of bulkiness feeling. Further, this contributes to maintaining of heat-retaining property. As a result thereof, a towel cloth having a pile formed of a non-twisted yarn can be applied to clothes. The non-twisted yarn is formed by twisting fibers of raw cotton that has an effective fiber length (34-42 mm) longer than the usual. Further, the non-twisted yarn is adjusted its adjustable range of reverse within a predetermined range (-10∼10%). Accordingly, fluff come-out can be suppressed as well as stability of quality can be achieved.
