Abstract
The utility model is related to polyaxial cut resistant kevlar fabrics, including are prepared by the twisting of p-aramid fiber long filament, braiding, thermal finalization and multicomponent impregnation.Polyaxial cut resistant kevlar fabric prepared by the utility model has special braiding structure, imparts higher belt cutting-resisting property, while having good snugness of fit；It solves influence of the ultraviolet light to aramid filament color and mechanical property by multicomponent impregnation, enhances the plyability of fiber and rubber；The novel cut resistant fabric can be widely used for the fields such as cut resistant protective clothes, tactical vest, Cutting-resistant tire.
Description
Technical field
The utility model is related to individual protection fields, it is also possible to be related to rubber product field, and in particular to a kind of polyaxial
Cut resistant kevlar fabric.
Background technology
Aramid fiber have high-strength, Gao Mo, high-temperature stability, at present by aramid filament prepare fabric be mainly woven fabric,
Laminated cloth, knitting fabric and cord fabric.Aramid fiber woven fabric and laminated cloth have the function of certain cut resistant, but due to its surface density
It is larger, fabric pore is smaller, snugness of fit is poor, is currently used primarily in flak jackets and bulletproof halmet.As well as its face
Density is larger, fabric void is smaller, and rubber raw materials cannot penetrate the gap, thus will produce lamination, therefore cannot be used for
Polyaxial cut resistant protecting tyre.Though aramid fiber cord fabric can be used as tire reinforcing material, only unidirectional humidification cannot
Realize polyaxial cut resistant protection.
Although it is larger thus also softer that aramid fiber is knitted fabric fabric pore structure, still lack with skin contact easypro
Adaptive.It cannot be used for special war, traffic police's tactical vest；Although the fabric of aramid fiber knitting simultaneously can hold rubber raw materials and penetrate, aramid fiber
Material and rubber raw materials bonding force are poor.
Invention content
Technical problem to be solved in the utility model is existing for the above-mentioned prior art deficiency, provides one kind
Intensity height, flame-resistant high-temperature-resistant, kevlar fabric comfortable and easy to wear, while having the function of polyaxial cut resistant, it is combined with rubber raw materials
The tyre material of good, alternative cord fabric.
The technical problems to be solved in the utility model is realized using following technical scheme：
A kind of polyaxial cut resistant kevlar fabric, by several aramid filament twisting at yarn, the yarn is through weaving into virtue
Synthetic fibre fabric, unlike the prior art：The outer surface of the kevlar fabric is stained with affine with aramid fiber and rubber raw materials
Glue-line.
Warp knit is for weft knitting in knitting, is to be linked to be fabric using warp thread stringer ring formation, it is formed by
Coil is arranged along warp thread direction, is mutually socketed to form by adjacent yarn.Extensibility and draftability are relatively low compared with weft-knitted fabric,
But there is preferable belt cutting-resisting property just because of this, especially in warp thread direction.And it to be formed since adjacent yarn is mutually socketed
One face, thus it is provided with polyaxial belt cutting-resisting property.Outer surface is stained with the glue affine with aramid fiber and rubber raw materials simultaneously
Layer, the glue-line according to the difference of its raw material, can be formed good wearing comfort or with the good compatibility of rubber raw materials.
The kevlar fabric is knitted to form the pore structure of quadrangle or hexagon.Form such pore structure not only work
Skill is simple, fabric appearance looks elegant, and soft texture is ventilative, and pore structure can hold rubber raw materials and fully penetrate, and composite performance is more
It is good.
Preferably, the density of the p-aramid fiber long filament is 200 ~ 3000 Denier, further preferred 400-1500 is red
Neil；The surface density of the kevlar fabric is every square metre 100 ~ 400 grams, further preferably 150-350 grams every square metre.
Preferably, the twist coefficient of the yarn is 0.7 ~ 1.5, further preferred 0.85 ~ 1.25.Twist direction is Z-direction.It twists
To the direction for referring to Yarn twisting in the textile industry.Generally either right-laid also referred to as S is twisted or Z is twisted for left-hand lay.Twisting system
The number characterization twist, the soft and outstanding twist of fabric is small, and the very refreshing twist is big.Twist coefficient can meet deflection and softness for 0.85 ~ 1.25
The unification of degree；Twist direction be Z-direction and knitting needle direction always, it is not easy to the twist reduces.
Further, the glue-line includes first glue-line affine with the outer surface of the kevlar fabric, at the same with institute
State the outer surface of the first glue-line and the second glue-line that rubber raw materials are affine.The production of different purposes can be prepared as needed in this way
Product, while reducing material cost.
Preferably, the aperture of the gap pore structure is 0.1cm-2cm.
Compared with prior art, the utility model efficiently solves that belt cutting-resisting property existing for kevlar fabric is poor, woven fabric
The problems such as compound poor, strength is low, intensity is unidirectional with rubber.Make cut resistant coefficient be not less than level Four, while can meet tactical vest,
The requirement of cut resistant clothes and protecting tyre.
Description of the drawings
Fig. 1 is the structural schematic diagram after the utility model single yarn adherency glue-line.
