Stitching process: Industrial grade double line chain stitching (needle spacing ≤ 3mm) is used, combined with hot melt adhesive glue fixation. The tensile strength of the seam is ≥ 800N, which is more than twice that of traditional single line stitching. Edge treatment: The edges around are folded and wrapped, with a width of 2cm, to prevent cotton fibers from being exposed and extend their service life. High elasticity strap system, quick fixing solution Strap parameters: Equipped with 2 adjustable length elastic straps (width 4cm, tensile strength ≥ 1500N), suitable for tying objects with a maximum circumference of 200cm. Fixed method: Adopting a plug-in design, the tightness can be adjusted within 3 seconds, and combined with the reinforcement ring buckle on the edge of the blanket, it forms a multi-point fixed structure. Cleaning method: Supports cold water machine washing (gentle mode), hangs and dries to restore fluffiness, avoiding material aging caused by high temperature drying. Storage design: Equipped with a storage bag (size 40cm × 25cm), the volume is reduced to 1/5 of the original volume after folding, and the weight is only 3.2kg, making it easy to carry.
