Document Type: Fabric Technology White Paper
1. Technology Overview
ChisuCutWeave™ is a proprietary lightweight cut-resistant knitted fabric architecture developed by ChisuSport. It is based on a combination of ultra-high-molecular-weight polyethylene (UHMWPE), high-performance polyethylene (HPPE), non-glass inorganic fibers, elastic yarns, and skin-contact yarns.
Rather than representing a single fabric, ChisuCutWeave™ is a configurable material and knitting technology platform. By adjusting fiber composition, knitting structure, elasticity, fabric weight, and surface treatments, the architecture is designed to achieve different levels of cut resistance while maintaining flexibility, comfort, and relatively low fabric weight.
The technology is intended for sports involving potential blade contact, sharp-edge abrasion, or high-speed friction, including short-track speed skating, competitive skiing, ice hockey, and kart racing.
2. Material System and Functional Components
The architecture integrates several material components, each serving a specific function:
- UHMWPE: The primary cut-resistant fiber, valued for its high strength-to-weight ratio, abrasion resistance, and chemical resistance.
- HPPE: A high-strength polyethylene fiber system that contributes to tensile strength and resistance to blade penetration.
- Non-glass inorganic fibers: Reinforcing components intended to improve thermal stability, dimensional stability, and resistance to blade penetration. The system explicitly excludes glass fibers to reduce potential skin irritation associated with broken fibers.
- Elastic yarns: Provide multidirectional stretch, recovery, garment shape retention, and freedom of movement.
- Skin-contact yarns: Fine-denier nylon or functional yarns designed to improve moisture management, reduce friction, and enhance next-to-skin comfort.
- Surface treatments: Functional finishes intended to improve blade-sliding behavior, low-temperature flexibility, antibacterial performance, and pilling resistance.
The core principle is to achieve cut resistance through the combined effects of fiber engineering, knitting structure, elastic-yarn configuration, and surface treatment, rather than relying solely on increased fabric thickness.
3. Key Technical Mechanisms
3.1 Fiber-Level Cut Resistance
UHMWPE and HPPE offer high tensile strength and specific strength. When a sharp blade contacts the fabric, the fibers can deform, redistribute local loads, slide within the knitted structure, and absorb energy, potentially reducing the depth of blade penetration.
3.2 Knitted-Structure Engineering
Knitted fabrics offer flexibility and deformability. ChisuCutWeave™ uses controlled high-strength yarn orientation, localized stitch-density adjustments, integrated cut-resistant and elastic layers, and selected floating-yarn, inlay-yarn, or double-layer constructions.
These structural approaches are intended to improve resistance to cutting while preserving the stretch and mobility required for competitive sports.
3.3 Elasticity Optimization
Elasticity is configured according to the requirements of different sports:
- Short-track speed skating: High recovery, low hysteresis, and unrestricted hip movement during cornering.
- Ice hockey: Resistance to tearing and deformation under impact and tensile loading.
- Competitive skiing: Close fit, aerodynamic performance, and shoulder and elbow mobility.
- Kart racing: Abrasion resistance, resistance to seat-belt friction, and torso stability.
Elastic-yarn ratios, covered-yarn structures, and directional stretch properties can be adjusted to achieve the desired balance between protection and mobility.
3.4 Blade-Slip Surface Treatment
Blade-Slip is a proposed surface-treatment approach designed to encourage blades and sharp edges to slide along the fabric surface rather than penetrate directly into it.
The intended effect is to reduce instantaneous penetration depth without substantially compromising breathability, hand feel, or dimensional stability after washing.
The technology does not claim to make the fabric completely cut-proof.
3.5 Cold-Flex Low-Temperature Adaptation
Cold-Flex refers to a material-selection and elastic-formulation approach intended to reduce stiffening at sub-zero temperatures. It aims to preserve flexibility, elastic recovery, and stable cut-resistance performance in cold-weather sporting environments.
4. Configurable Fabric Architecture
ChisuCutWeave™ can be configured across several dimensions:
- Fabric weight: 180–380 g/m².
- Cut-resistance classification: EN 388 Coupe, ISO 13997 TDM Levels A–F, and ANSI/ISEA 105 Levels A1–A9, subject to applicable testing and verification.
- Elasticity: Low, medium, high, or four-way stretch.
- Skin-contact characteristics: Next-to-skin fabrics, outer-shell materials, or base-layer constructions.
- Functional finishes: Blade-Slip, antibacterial treatment, anti-pilling treatment, low-temperature flexibility enhancement, and abrasion-resistant finishes.
- Knitting structures: Single-face, double-face, integrated multilayer, localized inlay, and composite cut-resistant/stretch constructions.
This modular approach allows the same underlying technology platform to serve different performance requirements without requiring a single fixed fabric specification.
5. Representative Fabric Matrix
The white paper presents the following representative configurations:
These figures are presented as typical fabric-level specifications, not classifications of finished garments. Actual performance must be confirmed by test reports for the relevant production batches.
Importantly, Coupe and TDM ratings are obtained using different test methods and cannot be directly converted into one another. Both should be reported when both have been tested.
6. Testing and Certification Framework
The proposed evaluation framework covers cut resistance, durability, mechanical performance, comfort, and chemical safety.
- EN 388:2016 Coupe: Evaluates resistance to cutting using a rotating circular blade.
- ISO 13997 / EN ISO 13997 TDM: Evaluates resistance to cutting using a straight blade under a specified cutting force.
- ASTM F2992 / ANSI/ISEA 105: Provides a North American framework for cut-resistance testing and classification.
- GB/T 8629: Washing and drying procedures for textile testing.
- GB/T 5453: Air permeability.
- GB/T 12704: Water-vapor transmission.
- GB/T 19976: Bursting strength.
- GB/T 3917.2: Tear strength.
- GB/T 2912.1, GB/T 7573, and GB/T 17592: Testing related to formaldehyde, pH, and certain restricted azo dyes.
- GB 31701 / OEKO-TEX: Relevant product-safety or textile-testing frameworks, where applicable to the product and certification scope.
The white paper recommends reporting cut resistance using a dual-method format, such as EN 388:2016 Coupe Level Lx + ISO 13997 TDM Level Ay, with the actual levels supported by test reports.
This approach is intended to provide a more complete technical description, particularly because blade dulling during Coupe testing can affect the interpretation of results for certain high-strength fiber systems.
7. Technical Value and Market Positioning
ChisuCutWeave™ is positioned as a configurable technical textile platform that seeks to balance three competing requirements:
- Protection: Resistance to cutting, abrasion, and sharp-edge contact.
- Athletic performance: Low weight, stretch, recovery, and freedom of movement.
- Wearability: Skin-contact comfort, breathability, low-temperature flexibility, and durability.
Its potential differentiation lies in integrating cut-resistant fibers with elastic knitted structures and application-specific surface treatments. Rather than offering only a heavy protective textile, the platform is designed to support close-fitting, performance-oriented sportswear.
8. Conclusion
ChisuCutWeave™ represents ChisuSport’s proposed approach to lightweight cut-resistant knitted fabrics for high-performance sportswear. Its core concept is to combine high-strength polyethylene fibers, non-glass reinforcing fibers, engineered knitting structures, elastic-yarn optimization, and functional surface treatments within a configurable architecture.
The technology may be relevant to speed skating, skiing, ice hockey, kart racing, and other activities involving sharp-edge or abrasion hazards.
However, the specifications and performance levels described in the white paper should be treated as manufacturer-stated technical information until supported by independent laboratory reports. Fabric-level cut-resistance ratings do not, by themselves, establish the protective performance of a finished garment under actual sporting conditions. Final product selection should also consider seam construction, coverage, fit, abrasion, washing durability, and sport-specific safety requirements.
