Embodiment

[0011] Nylon 66 polymer slices are melt spun under the conditions of spinning temperature 270°C and discharge rate 8.5g / min, and weave multifilaments consisting of 20 monofilaments through 2 godet rolls. The breaking strength of the multifilaments is It is 4.9-5.2cN / dtex. A 20dtex false-twisted yarn is produced by false-twisting processing. The obtained false-twisted processed yarn was used for warp and weft, and a double tongue structure was woven by a water jet knitting machine. Refining, setting, calendering and soft finishing are carried out on the obtained fabric according to conventional methods to obtain a breathable fabric, wherein the multifilament accounts for 75-80%.

[0012] The air permeability of the above-mentioned low air permeability fabric is less than 1.8cc / cm 2 / s. Preferably, the multifilament accounts for 75-80%.

[0013] In the present invention, the method for producing multifilaments is not particularly limited, and can be produced, for example, by...

Abstract

The invention discloses a low-air-permeability fabric which is composed of polyamide synthetic fiber with the 15016dtex fineness. The overall coverage coefficient is 1800-2000, multifilament composed of monofilaments arranged in two-layer mode exists in the warp direction and weft direction simultaneously and is false-twisting processed yarns, the fineness is 20-22dtex, and the monofilament number is 18-20. The coverage coefficient of at least one of the warp direction and weft direction in which the multifilament exists is 700-900. The low-air-permeability fabric has low air permeability, and the low air permeability can be still kept after multiple-time washing. In addition, the low-air-permeability fabric has the advantages of being high in tearing strength, light, thin and soft in touch and can be applied to down garment, down jackets, bedclothes, sleeping bags and the like.

Description

technical field [0001] The present invention relates to a fabric with low air permeability. Background technique [0002] Fabrics used for down garments or bedding require less air permeability, thereby inhibiting the escape of cotton or down. In addition, it is also required to be thin and light. Conventionally, natural fibers such as silk and cotton, which are excellent in texture and comfort, have been used for the above-mentioned fabrics. However, the fabric made of natural fibers has low tear strength and poor durability. Therefore, especially when it is used as a down garment, there is a problem that cotton or down emerges from elbows or sleeves. On the other hand, polyester multifilaments, nylon multifilaments, or composite synthetic fiber fabrics of these are often used for the above-mentioned fabrics because of their excellent mechanical properties. These fabrics are soft, lightweight, and have excellent wind resistance, water repellency, and fastness, so they ar...
