Description

Sewing thread for feathered fiber products that can effectively prevent feather pull-out and puckering while realizing excellent stretchability and light weight, and feathered fibers using the sewing thread for feathered textile products The present invention relates to a product and a method for producing a fiber product containing feathers.

Conventionally, by using feathers inside a cold protection device such as a jacket, jumper, or blouson, an air layer having a high heat insulating effect is efficiently formed, and a high heat retaining effect is obtained.
For example, a down jacket in which feathers are filled between a lining in contact with the wearer and a surface in contact with the outside world is well known.

In the down jacket, it is common to quilt after stuffing feathers between the outer and lining, but the down jacket made by such a method quilts from above the stuffed feathers, There was a problem that feathers were detached from the quilting stitches. When the feathers are detached, not only does the wearer feel uncomfortable, but also the thermal insulation and comfort of the down jacket are reduced.

For this, it is common to provide an intermediate fabric called a downpack that is sewn in a bag shape between the outer material and the feathers, and between the lining and the feathers. ) Since a high-density fabric is used for prevention, the stretchability is reduced and the weight is increased, so that it is not particularly suitable for applications such as sportswear.

For example, Patent Document 1 discloses that in order to prevent the quilting portion from coming out of the feathers, the intermediate fabric (down pack) is sewn in advance with two stitches, and later on the intermediate fabric on the intermediate fabric. Or down wear that prevents the feathers from slipping out from the front seam by stacking the back fabric and forming a seam at the center of these two stitches and stitching the front fabric or back fabric and the middle fabric together Have been described.
However, in such a method, the manufacturing process is extremely complicated, and problems such as a decrease in stretchability and an increase in weight due to the use of the inner fabric have not been solved.

Patent Document 2 discloses that a foamed emulsion resin is coated on a base fabric, a fabric such as gauze having a lower stretchability than that of the base fabric is layered on the coating layer, and the coating layer is heated and cross-linked. Prevention fabric is described.
However, such a method also requires a coating process and a heat-crosslinking process, so that the manufacturing process is extremely complicated, and the use of a fabric having low stretchability causes problems such as a decrease in stretchability and an increase in weight. It was not solved.
