I. Functional Classification and Core Indicators of Gloves
(Cited from ASTM D1207-23 Performance Testing Standards for Hand Protection Equipment)
Gloves can be divided into six functional types according to usage scenarios, with their core performance indicators as follows:
1. Winter Cold Protection Gloves
Key Parameters:
- Thermal Insulation Coefficient (CT value): ≥0.25clo (ISO 11079-3 thermal resistance testing standard), CT value of wool blend materials is typically 0.3-0.5clo
- Waterproofness: Seams must pass AATCC 127 waterproof test (pressure ≥30kPa)
- Typical Materials: Cashmere (fiber diameter 14-16μm), Thinsulate™ thermal insulation cotton (thermal conductivity 0.022W/(m·K))
2. Office Commuting Gloves
Business Requirements:
- Touchscreen Compatibility: Capacitive sensing material at fingertips ≤0.3mm thick (ensuring sensitivity >90%)
- Leather Grade: Preferred Class A calfskin (pore density 12-15 pieces/mm², referring to ILCA leather grading standards)
- Stitching Process: Stitch pitch ≤3mm (ASTM D3389 stitch strength test)
3. Outdoor Work Gloves
Industrial Standards:
- Abrasion Resistance Index: Passes ASTM D4060 Taber Abrasion Test (weight loss ≤5mg after 1000 cycles)
- Cut Resistance Level: Meets EN 388:2016 Class F (blade pressure ≥25N)
- Common Materials: Kevlar® aramid (tensile strength ≥2900MPa), PVC-coated canvas

Special Material Analysis:
- Thinsulate™ Thermal Insulation Cotton: 1.5 times warmer than wool at the same thickness, 30% lighter (3M laboratory data)
- DWR Waterproof Treatment: Forms a hydrophobic layer with a contact angle >110° on the fabric surface (AATCC 22 spray test standard)
III. Ergonomic Purchase Points
1. Precision Size Measurement
Three-step Measurement Method:
- Palm Circumference: Use a soft tape to encircle the widest part of the palm (excluding the thumb). Standard palm circumference is 20-23cm for adult males and 17-20cm for females.
- Finger Length: Measure from the fingertip to the metacarpophalangeal joint, with the middle finger length accounting for about 45% (in line with the golden ratio of hand proportions).
- Thenar Circumference: The maximum distance when the thumb and index finger are spread, affecting glove flexibility (recommended to reserve 5-8mm of activity space).
2. Adaptation for Special Groups
- Hyperhidrotic Hands: Choose palm perforation design (aperture 2-3mm) or Coolmax® moisture-wicking material (moisture content <5%)
- Arthritis Patients: Prioritize elastic wrist openings (elongation ≥150%) + Velcro adjustment to reduce wearing pressure
- Large Palms: Choose seamless finger 拼接 design (reduce friction points), with finger root stitches offset by 1-2mm
IV. Scenario-based Purchase Guide
1. Extreme Cold Climate (below -20℃)
Professional Configuration:
- Outer layer: Waterproof cowhide (thickness 1.2-1.4mm) + DWR coating
- Middle layer: 3M™ Thinsulate™ 400g thermal insulation cotton (CT value 0.52clo)
- Inner layer: Merino wool (odor-proof treatment, odor level ≤2, ISO 17299 standard)
Measured Data: This configuration maintains hand skin temperature above 10℃ in -30℃ environments.
2. Business Occasions
Etiquette Norms:
- Color: Black/dark brown (in line with Savile Row dress standards)
- Material: Class A deer skin (surface gloss 15-20GU, GB/T 41689 detection)
- Details: Invisible touchscreen layer at fingertips (thickness 0.15mm), no need to remove gloves when answering calls.
3. Outdoor Sports (mountaineering/cycling)
Functional Design:
- Palm non-slip pattern: Diamond pattern (friction coefficient ≥0.6, ASTM C1028 test)
- Knuckle protection: TPU crash pad (Shore hardness 80A)
- Wrist support: Elastic webbing + metal buckle (load-bearing ≥5kg)
4. Summer Daily Use
Breathable Solutions:
- Back of hand mesh: Aperture 1.5mm, air permeability ≥1000mm/s (GB/T 5453 test)
- Fingertip hollow design: 30-40% exposure area reduces sultriness (ergonomic research shows)
V. Maintenance and Life Management
1. Cleaning Technical Specifications
Material |
Cleaning Method |
Key Parameters |
Sheepskin gloves |
Special leather cleaner (pH4.5-5.5) |
Wiping force ≤1.5N·cm² |
Knitted gloves |
Cold water machine wash (speed ≤600rpm) |
Temperature ≤30℃, no bleaching |
Waterproof gloves |
Neutral detergent + soft brush |
Seam cleaning pressure ≤0.5MPa |
2. Storage Environment Standards
- Temperature: 18-22℃, humidity: 45-55%RH (referencing museum collection preservation specifications)
- Supports: Use finger shapers (material hardness Shore 20A) to maintain the three-dimensional shape of gloves
- Periodic Maintenance: Apply mink oil (oil content ≥60%) to leather gloves quarterly to restore fiber flexibility
VI. Common Purchase Misunderstandings and Solutions
1. Blind pursuit of thickness leads to reduced flexibility
Case: A brand's winter gloves exceed 2cm in thickness, increasing finger bending resistance by 40%.
Solution: Choose a layered design (outer waterproof + inner thermal insulation), with total thickness controlled within 1.5cm.
2. Ignoring ergonomic design for finger movement
Data: The operation error rate of traditional five-finger equal-length gloves is 27% higher than ergonomic designs (MIT hand movement research).
Optimal Choice: Comply with the "gradually shorter fingertips" principle (middle finger > index finger > ring finger > little finger), with an error ≤2mm.
3. Poor-quality materials cause skin allergies
Test: Formaldehyde content in inferior PU gloves may exceed standards by 5-8 times (GB 18401-2020 standard limit).
Recommendation: Choose materials certified by OEKO-TEX® 100 (formaldehyde content ≤75ppm).
Conclusion:
Glove selection is a systematic project integrating material science, ergonomics, and scenario requirements. It is recommended that frequent users undergo 3D hand scanning through professional institutions (such as 3D Hand Scanner systems) to obtain precise size data. From professional protection in extreme cold environments to etiquette adaptation in business occasions, scientific selection not only enhances user experience but also extends equipment life, achieving a balance between functionality and aesthetic value.
