Drilling out prevention structure of feathers

Abstract

The invention provides a going-out prevention structure for feathers, wherein the penetration prevention process for feathers is no longer needed and the ventilation degree is high. Meanwhile, feathers are effectively prevented from going out without the time of quilting. The going-out prevention structure comprises a plurality of folds (2) formed by an entire side cloth (1) filled with feathers and small feathers. A plurality of retaining lines (3) are erected at the spacing of 1 mm - 15 mm so as to the top of the plurality of folds (2). Therefore, a bag space for being filled with feathers is formed under the condition of adopting the quilting method when the surface side cloth (1a) or the inner cloth (1b) is engaged via the cylinder knitting or the double-sided heterochrosis pattern knitting.

Description

technical field [0001] The present invention relates to a structure for preventing feathers from coming out of a feather futon or feather clothing. Background technique [0002] In the past, feather bags used in feather futons or feather bags used in jackets, coats, vests and other feather clothing materials using feathers are usually made of thin and high-density fabrics that use fine yarn counts or even fine deniers. It is made of material with down penetration processing (ダゥンプル一フ). This is because the drapability of the feathers is utilized as effectively as possible and the feathers in the bag body are difficult to drill out from the side fabrics. The down penetration prevention process is a kind of calendering process, and heat and pressure are applied to the side fabrics by calendering the side fabrics constituting the feather bag body with rollers, thereby deforming the woven thread itself, thereby reducing the size of the thread and thread. The gap between them inh...

Problems solved by technology

[0011] (2) In order to obtain low air permeability, the filling time of the feather relative to the bag becomes longer, and the feather bag is airtight during use, which hinders the shape recovery after the feather bag is pressed and deformed

[0013] In addition, although the invention described in Patent Document 2 can obtain good elasticity (stretch) through pleating processing, if the air permeability is not reduced to 3 cm through down penetration preventi
