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
The present invention relates to a kind of low alry fabric.
Background technology
Cloth for down coat or bed clothes requires lower aeration, thereby suppresses getting out of cotton or eider down.In addition, also requirement is unexpectedly frivolous.In above-mentioned cloth, used natural fabrics such as having the silk of feel, comfortableness excellence or cotton in the past.But, therefore especially as in the situation of down coat, there is the problem that cotton or eider down and so on occur to get out from ancon or sleeve part in the little and poor durability of the tearing strength unexpectedly that formed by natural fabric.On the other hand, from the performance of its mechanical property excellence, most polyester multifilament, nylon multifilament or these composite synthetic fibre fabrics of using in above-mentioned cloth.The excellences such as these fabric sofetenings, light weight and windproof, hydrophobicity and fastness, are therefore used in overcoat, jacket, golf shirt, physical culture with outdoor shirt etc. more.But, want to guarantee when suppressing the resistance to eider down penetrability getting out of eider down, fabric to be made to fine and close structure, there is the problem of stiffen fabrics.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of low alry fabric, the above-mentioned defect existing to overcome prior art.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of low alry fabric, the fabric that polyamide-based synthetic fiber by fiber number 15-16dtex form, total coverage coefficient is 1800-2000, in warp-wise and broadwise, exist simultaneously and between monofilament, be arranged in the multifilament of 2 layers, described multifilament is false-twisted yarn, fiber number 20-22dtex, wherein monofilament number is 18-20; And the coverage coefficient of the warp-wise that described multifilament exists or at least one direction of broadwise is 700-900.
As preferably, described multifilament accounts for 75-80%.
As preferably, the fracture strength of described multifilament is 4.9-5.2cN/dtex.
As preferably, the venting quality of described low alry fabric is less than 1.8cc/cm
2/ s.
In the present invention, the throwing method of multifilament is not particularly limited, for example, can be spun the spin-drawing continuous apparatus that the mode of prolonging carries out or be manufactured with 2 operations with device for spinning and stretching device by use utilization.
Low alry fabric provided by the present invention has lower aeration, and repeatedly still maintaining low aeration after washing, has advantages of that tearing strength is high, frivolous and soft simultaneously, can be applicable to down coat, eider down jacket, bed clothes, sleeping bag etc.
The specific embodiment
Embodiment
Nylon 66 polymer chipss, to carry out melt spinning under 270 ℃ of temperature of spinning, spray volume 8.5g/ minute condition, are weaved to the multifilament that 20 monofilament form by 2 godet rollers, and the fracture strength of described multifilament is 4.9-5.2cN/dtex.By the false-twisted yarn of false twisting processing and fabricating 20dtex.The false-twisted yarn obtaining, for warp thread and weft yarn, is weaved to two tongues by water spray braiding machine and organized.According to conventional method, the fabric obtaining is carried out to refining, setting, calendering processing and soft finish, obtain alry fabric, wherein, described multifilament accounts for 75-80%.
The venting quality of above-mentioned low alry fabric is less than 1.8cc/cm
2/ s.As preferably, described multifilament accounts for 75-80%.
In the present invention, the throwing method of multifilament is not particularly limited, for example, can be spun the spin-drawing continuous apparatus that the mode of prolonging carries out or be manufactured with two operations with device for spinning and stretching device by use utilization.
