↪Actually welcome to the concept of the HEAT TRANSFER

↪basically as here given ,

↪Wool traps air in its layers , due to the structural openings and closings ,

↪since here , also we know that Air Is the bad conductor of heat,

↪so from this fact , we can say that , the air trapped in the layers of wool is bad conductor of heat , so it just defines that wool is bad conductor of heat ,

↪Now we know that , Any bad conductor never conducts anything through it or it block the passage to pass through it ,

↪So eventually here ,the Air acts as a barrier to the body heat to escape out of the wool and so thus we feel warm in winter
