The warmth core of lamb wool Winter blanket is high-density fluffy wool+heat storage air layer+double-sided composite. Its advantages include fast heating, strong temperature locking, light and soft skin friendly, which is 30% warmer than ordinary blankets and suitable for environments ranging from -5 ℃ to 15 ℃.
1、 Thermal insulation principle (why is it warmer)
Fiber structure: Ultra fine fibers (15-20 μ m)+three-dimensional curling, forming a large number of static air chambers. Air is a poor conductor of heat, with strong temperature locking and insulation.
Fluffness: High fluffiness (≥ 600g/㎡), dense and upright fluff, one gram of fluff locks 30 times the air, the fluffiness is warmer.
Double sided composite (mainstream): A-side flannel/milk velvet (250g/㎡) fits snugly without freezing; B-side thickened lamb wool (300g/㎡) for heat storage, with a temperature increase of 8-10 ℃ in 2 minutes.
Moisture absorption and temperature regulation: It can absorb 35% of its own weight of moisture, without stuffiness or dampness, and does not freeze on wet and cold days, while moisturizing on dry and cold days.
2、 Core selection criteria (avoiding pitfalls)
- Material (preferred)
High end: Polyester fiber+acrylic blend (imitation lamb wool, durable without shedding hair, 100-200 yuan).
Mid end: Full polyester (soft and easy to maintain, 60-120 yuan).
Low end: ordinary synthetic fiber/low cotton content (easy to board and shed hair,<50 yuan, not recommended).
✅ Must see labels: “Thickened lamb wool”, “AB double-sided”, “Weight ≥ 500g/㎡”. - Craftsmanship (determines durability)
Fleece density: dense, short, smooth, without sparse/exposed base, quick rebound under hand pressure.
Edge locking: Triangular needle/double line edge locking, not easy to roll or crack.
Anti static/no shedding: Optimal anti-static treatment+pre washing to reduce shedding and static electricity. - Size (scene adaptation)
Individual lunch break: 100 × 120cm (office/student).
Sofa/Children: 150 × 200cm (universal).
Double bed: 200 × 230cm (1.8-meter bed).
