Abstract
The present invention provides a webbing for a seat belt for protecting a seat occupant of a vehicle or aircraft against a shock in the event of collision. The webbing for seat belt is structured so that acrylic resin is attached fast to the surface of a fabric formed from multi-filament yarns of polyethylene terephthalate as synthetic fiber, in which the acrylic resin forms a facial resin layer by bridging with a cross linking agent having three to five functional radicals and also the acrylic resin and cross linking agent undergo a bridging reaction in the structure of the multi-filament yarn.
Description
Technical field
The present invention relates to a kind of band fabric for safety belt (webbing) that is used to protect passenger on vehicle or the aircraft etc. to exempt from the impact when colliding.
Background technology
In the past, in No. 2693894 communique of Japan special permission for example, disclose a kind of for prevent wearing and tearing because of band fabric for safety belt and batching apparatus diminish the flatness of webbing and cause towards batching of batching apparatus inside bad, the technology of carrying out the resin coating on the surface of webbing.Specifically disclose and had flatness on the surface that makes band fabric for safety belt and use in the technology of silicon, in order to prevent silicon to be come off from the surface of band fabric for safety belt, solidify the technology of propylene base system resin and silicon mixture at the band fabric for safety belt surface impregnation by the light decomposition.
But,,, must improve ABRASION RESISTANCE, thereby can not be created in the bad problem of accommodating in the Webbing take-up device for conventional art because of for example raising of the safe benchmark of vehicle recently.
Summary of the invention
For this reason, the purpose of this invention is to provide the band fabric for safety belt that a kind of resin that makes the webbing surface is difficult to come off, ABRASION RESISTANCE is improved.
Above-mentioned technical problem is solved by each technical scheme of the present invention.
The present invention is a kind of band fabric for safety belt, surperficial bonding propylene base system resin at the webbing that constitutes by multifilament as the polyethylene terephthalate of synthetic fiber, it is characterized in that, this propylene base system resin is crosslinked to form surface resin layer by the crosslinking agent with 3～5 functional groups, and, this propylene base system resin and this crosslinking agent cross-linking reaction in the multifilament tissue of band fabric for safety belt.
Adopt words of the present invention, this propylene base system resin and crosslinking agent are immersed in the webbing respectively, be immersed in afterreaction between the long filament of multifilament, by having the crosslinking agent of 3～5 functional groups, multifilament and propylene base system resin can become 3 dimension crosslinked configuration on the surface of webbing, to form the firm surface resin layer of physical bond.
In addition, as the present invention, it is the copolymer of main component that propylene base system resin is preferably with the methacrylate.
The copolymer that with the methacrylate is main component is affine with the multifilament chemistry that is made of polyethylene terephthalate, owing to improved to the in-house impregnability of silk, by forming 3 crosslinked configuration of tieing up, can obtain more firm physical bond with the crosslinking agent reaction.
In addition, as the present invention, it is the copolymer of main component that propylene base system resin also can be with the propenyl acid esters.
Have, it is 4.0 ~ 8.0g/m that the present invention adopts the pickup of propylene base system resin again
2, when the cooperation ratio of crosslinking agent was the formation of 10～30wt%, the TENSILE STRENGTH of this surface resin layer after the final cross-linking reaction was 100N/cm
2, and degree of stretching is more than 500%, can bring into play mar proof, also can guarantee to determine the free degree of the multifilament of webbing pliability.
Be that as the present invention, the pickup of propylene base system resin is 6.0g/m better
2, the cooperation ratio of the crosslinking agent of propylene base system resin is 20wt% relatively.
The specific embodiment
As the silk thread that constitutes band fabric for safety belt, use the multifilament of the good polyethylene terephthalate of light resistance.Because color matching is few, is a kind of only material for the band fabric for safety belt that must pay attention to aesthetic appearance.Warp thread is 1100～1700dtex, and weft yarn is 550～700dtex.Weaving structure is 2up, the twill-weave of 2down, and warp count is 120～170 pieces/inch, weft count is 17～22 pieces/inch.
Be used to be adhered to the composition of the surface resin on the band fabric for safety belt, use with the copolymer of methacrylate as main component.As other propylene base system resin, also can use for example with the copolymer of propenyl acid esters as main component.
Aforesaid is that the copolymer and the crosslinking agent of main component is immersed in the webbing equally respectively with the methacrylate, be soaked in afterreaction between the long filament of multifilament, 3 dimension crosslinked configuration by having in the long filament tissue form firm surface resin layer that be made of the propenyl acid esters, physical bond on the surface of the webbing that is made of multifilament.
The physical property of the surface resin of band fabric for safety belt is that the coating weight of propylene base system resin is 6.0g/m
2, the cooperation ratio of crosslinking agent is 20wt%.The TENSILE STRENGTH of this surface resin layer is 200N/cm
2, and degree of stretching is 700%.
Comparative example
Below, for formation with reference to the explanation comparative example.As the silk thread of the band fabric for safety belt that constitutes comparative example, use the multifilament of the excellent polyethylene terephthalate of light resistance.Warp thread is 1670dtex, and weft yarn is 700dtex.Woven construction is 2up, the twill-weave of 2down, and warp count is 250～300/m, weft count is 700～850/m.
Be used for being adhered to the composition of the surface resin of band fabric for safety belt, use polyethet surfactant.
The surface treatment of band fabric for safety belt the has been fusion surfactant of dimethyl-silicon, pickup is 3.0g/m
2This surface treatment is a surfactant owing to do not form resin film of the present invention, not with the present invention in the suitable value of TENSILE STRENGTH, degree of stretching.
The mechanical endurance test result
The present invention and comparative example in the batching apparatus of safety belt, are carried out mechanical endurance test, the reduction of the power of relatively extracting number of times out and in batching apparatus, taking in (below, be called the power of taking in).
When product of the present invention was 200 times at the extraction number of times, the power of taking in only reduced about 7%, but in comparative example, the power of taking in reduces about 29%.And when the extraction number of times of product of the present invention was 1000 times, the power of taking in only reduced about 16%, and in comparative example, the power of taking in reduces about 33%.When the extraction number of times of product of the present invention was 2000 times, the power of taking in reduced about 22%, and in comparative example, the power of taking in reduces about 42%.
So, only in the comparison initial stage of extracting number of times out, the power of taking in of comparative example will be passed through rapid variation.Product of the present invention is compared with comparative example, because ABRASION RESISTANCE is excellent, long-term obviously use can prevent the reduction of the power of taking in.
The effect of invention
As above-mentioned, adopt words of the present invention, the surface resin of band fabric for safety belt is very Difficulty comes off, and can obtain the high band fabric for safety belt of wearability, for this reason, can obtain can not Safety belt occurs and in devices for taking-up, take in safety belt usefulness bad problem, that security performance is excellent Webbing.
