US-12623435-B2 - Tubular pocket fabric for preventing deposition of down

Abstract

The present invention provides a pocket fabric, including at least one tubular pocket, where each tubular pocket includes: 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; and at least one mesh barrier layer provided between two filling chambers and substantially perpendicular to the tubular sidewall, wherein the filling chambers are communicated with each other. The mesh barrier layer allows fluffy filler to be maintained in the filling chamber and substantially prevents it from moving to adjacent filling chambers, so that the filler cannot accumulate in one place due to gravity or other external forces. Therefore, the pocket fabric of the present invention can maintain the desired warmth retention property after a period of use with filler evenly distributed inside.

Description

PRIORITY CLAIM AND CROSS-REFERENCE This application claims priority to Taiwan Application No. 110131513 filed on 25 Aug. 2021, which is incorporated herein by reference. FIELD OF THE INVENTION The present invention relates to a pocket fabric, and in particular, to a pocket fabric that can allow for uniform fill distribution and maintain the desired warmth after a period of use. BACKGROUND Common methods to confer warmth retention to clothes may include using a double-layered fabric to form many filling areas between the layers for fillers such as down, cotton cloth, artificial resin cotton and the like, and filling between the two layers of fabric with a fluffy filler to make the filing area become a three-dimensional space, so that the air in the three-dimensional space contributes to the warmth retention property of clothes. For example, Taiwan Patent No. I583838B discloses a pocket fabric including a plurality of tubular pockets interwoven with a plurality of warp yarns and a plurality of weft yarns. The plurality of tubular pockets can be used for filling. As shown in FIG. 1 (i.e., FIG. 3 in Taiwan Patent No. I583838B), the pocket fabric 90 includes tubular pockets 91 vertically arranged. Filler can be filled into the inner space of each tubular pocket 91 from an upper opening 92 or a lower opening 93 of the tubular pocket 91. When users wear the pocket fabric 90, a plurality of tubular pockets 91 are arranged substantially parallel to the ground. However, after a period of use of the pocket fabric 90, the filler in the inner space of the tubular pocket 91 would accumulate at the lower opening 93 due to gravity. As shown in FIG. 2, only sparse filler 95 is retained in the area near the upper opening 92 of the pocket fabric 90, but the filler 95 present in the area near the lower opening 93 becomes denser. As a result, the warmth retention is gradually increased at the lower portion of the pocket fabric 90, but is gradually reduced at the upper portion, so the warmth retention of the fabric 90 is uneven, causing discomfort to on the wearer. In addition, no matter whether the tubular pockets are arranged vertically or horizontally, after the pocket fabric is washed several times, the filler may also accumulate in one place, causing discomfort to the wearer due to uneven warmth retention of the fabric. To prevent motion of the filler in the pocket fabric in the long tubular pockets causing an uneven distribution of the filler and affecting the warmth retention effect of the fabric, in some pocket fabrics, the long tubular pockets are filled with filler in a fixed shape, and the filler just fills up the inner space of the long tubular pockets, so that the filler cannot move in the long tubular pockets, referring to Taiwan Patent TW M433826; or some pocket fabrics include lattice pockets instead of long tubular pockets, referring to Japan Patent JP 3205779 U, with a small inner space for each lattice pocket, thereby reducing the uneven distribution of filler. However, if the pocket fabric is filled with filler in a fixed shape, additional processing and manufacturing costs are required for the filler. Lattice pockets require more pockets by volume than long pockets. Therefore, a complex manufacturing process is required and more seams need to be formed for the lattice pocket fabric, which cannot be filled with down, resulting in cold spots; and body heat will also dissipate through the seams, thereby reducing the effect of warmth retention. SUMMARY OF THE INVENTION An objective of the present invention is to provide a pocket fabric that can maintain the desired warmth retention property after a period of use with filler evenly distributed. The present invention provides a pocket fabric, including at least one tubular pocket, where each tubular pocket includes: 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; andat least one mesh barrier layer provided between two filling chambers and substantially perpendicular to the tubular sidewall, wherein the filling chambers are communicated with each other. In the present invention, each mesh barrier layer includes a plurality of yarn segments connected to a plurality of points on an inner side of the tubular sidewall. In the present invention, the yarn segments used to form the mesh barrier layer are elastic or non-elastic yarns. In the present invention, the distance between an end and a mesh barrier layer near the end is about 2 cm to about 20 cm. In the present invention, when a tubular pocket of the pocket fabric includes a plurality of mesh barrier layers, the distance between two adjacent mesh barrier layers is about 2 cm to about 20 cm. In the present invention, the pocket fabric includes a plurality of tubular pockets arranged in a direction perpendicular to a tubular sidewall of the tubular pockets, where the tubular sidewall of each tubular pock
