The present invention further includes a step of post-processing the synthetic fiber multifilament by an interlacing method, an air-texturing method, a draw texture method, or a false twisting method before the multi-woven fabric weaving process.

The processed yarn after the quartz processing has good warmth, touch and color.

The multi-woven fabric may be the double-woven fabric shown in Fig. 1 or the triple-woven fabric shown in Fig.

It is desirable to control the direct density to 250 to 500 T at the time of weaving multiple woven fabrics to effectively prevent the down filling agent from escaping to the outside.

Natural fibers or recycled fibers may also be used as part of yarns used in weaving multi-weave fabrics, and as part of warp and / or weft yarns.

Next, the multi-woven fabrics woven as described above are dyed under an emulsion force to produce multi-functional multi-woven fabrics.

It is preferable to add a pretreatment agent that promotes dye permeability during the above-mentioned salt solution process in order to improve the color saturation.

The above-mentioned salt solution can be carried out using a Ziegler dyeing machine or the like.
