Abstract

The method for producing an artificial duck down having good thermal insulation and resilency employs as warp a low melting point synthetic monofilament of 50-80 denier for 20-50 lines/inch and as fillings a 10-80 denier synthetic multifilament yarn consisting of 4.0-15 denier filaments for 50-150 lines/inch for warps and fillings to melt-fuse to each other in a plain weave, which is slit in the warp direction with a 0.5-1.2 mm width and then is cut in the length of 1-3cm.

The present invention relates to an artificial orifice excellent in heat retention and compression elasticity and a method for producing the same. Natural duck feather has excellent heat retention and compression elasticity, but its amount is limited, and as a substitute, crimped staple yarn, which has properties similar to natural duck feather, is used for warm clothes, sleeping bags, etc. It has also been used for toys. However, this crimped staple yarn had a problem that the heat retention and compression recovery rate were significantly inferior to that of natural duck feathers. The present inventors have endeavored to improve the above problems. As a result, we use low melting point synthetic monofilaments for warp yarns and weft yarns using synthetic filaments or fabricated yarns. By slitting at regular intervals and then cutting to a constant length, the inventors have invented artificial feathers, which are very similar to the physical properties of natural feathers, and a method of manufacturing the same.

The present invention is described in more detail as follows.

Using a low melting point synthetic monofilament (1) having a slope of 50 denier-800 denier and a weft yarn using a synthetic multifilament of 10 ^D- 80 ^D having a single yarn fineness of 0.4 ^D- 15 ^D or a processed yarn thereof (2), After weaving into plain weave with 20-50-50 per inch of weaving yarn and 50-150 weaving yarn for weaving yarn, we heat-weld it with a heating roller at 80 ℃ -150 ℃ and incline angle of 45 ° -90 ° In this figure, slitting was performed at intervals of 0.5-1.2 mm and then cut to have a length of 1-3 cm. The low melting synthetic monofilament used as the warp in the present invention is partially melted at 80 ° C.-150 ° C. to facilitate welding of warp and weft yarns in the heat treatment process after weaving. In addition, the low melting point synthetic monofilament used as a slope is better the lower the fineness, but if it is less than 50 denier, there is a difficulty in weaving, there is a problem of cost increase, and if the denier is more than 800 denier, the physical properties deteriorate. In the case of synthetic multifilament used as a weft yarn or a processed yarn thereof, the lower the fineness, the better. However, 10-80 denier is suitable because there are manufacturing techniques and cost problems according to the manufacture of three deniers. If it is 80 denier or more, heat retention will fall. In the present invention, when the slitting interval is shorter than 0.5 mm, the thermal insulation is poor and cannot be used for warm clothes and sleeping bags that require warmth. In addition, the higher the density of paper weft yarn, the higher the thermal insulation and compression elasticity of artificial ory wool, but are selected according to the intended use. Since the shape of the weft welded to the inclination varies according to the slitting angle, 45 ° -90 ° is appropriate in the weft direction for excellent heat retention and compression elasticity.

Example 1

The warp is made of hot melt 70 ^D monofilament, 30 bones / inch, and the weft yarn is nylon 40 ^D / 10 f 90 bones / inch. The slits were 90 °, 60 ° and 45 ° and cut to 25 mm in length.

Example 2

Weaving is made of hot melt monofilament, 100 ^D , 20 bones / inch, and weft yarns of 40 deniers of polyester (single thread fineness 6 ^D ), 70 bones / inch. The slits were 2.5 mm wide at 90 °, 60 ° and 45 ° and cut into 30 mm lengths. Table (1) is a score report comparing the physical properties of the artificial oral hair produced in Examples 1 and 2 with conventional crimped staples.
