Tubular pocket fabric for preventing deposition of down

A pocket fabric, comprising a plurality of tubular pockets, wherein each of the plurality of tubular pockets comprises:

• a tubular sidewall formed between two ends of the tubular pocket;
• at least two filling chambers formed between the two ends and surrounded by the tubular sidewall;
• at least one mesh barrier layer provided between two filling chambers and substantially perpendicular to the tubular sidewall, wherein the two filling chambers are communicated with each other, and wherein each mesh barrier layer comprises at least two yarn segments connected to two points on an inner side of the tubular sidewall;
• and
• filler filled in the filling chambers and being present in the mesh barrier layer,
• wherein the plurality of tubular pockets are arranged in a direction perpendicular to the tubular sidewall of each tubular pocket, and
• wherein the tubular sidewall between two of the plurality of tubular pockets comprises a plurality of connecting portions and a plurality of vents arranged alternately so that each of the plurality of vents is located between two of the plurality of connecting portions and one of the plurality of tubular pockets is communicated with an adjacent one of the plurality of tubular pockets through the plurality of vents, and
• wherein the mesh barrier layer in one of the plurality of tubular pockets and the mesh barrier layer in an adjacent one of the plurality of tubular pockets are arranged in a staggered form.
