Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.The element described in an accompanying drawing of the present invention or a kind of embodiment and feature can combine with the element shown in one or more other accompanying drawing or embodiment and feature.It should be noted that for purposes of clarity, accompanying drawing and eliminate expression and the description of unrelated to the invention, parts known to persons of ordinary skill in the art and process in illustrating.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not paying creative work, all belongs to the scope of protection of the invention.
Ultra-high molecular weight polyethylene is the polyethylene of molecular weight more than 1,000,000.The conventional art of ultra-high molecular weight polyethylene application prepares various product based on ultra high molecular polyethylene fiber.The technical scheme that various embodiments of the present invention provide, the conventional art applied with ultra-high molecular weight polyethylene is essentially different, it is the revolutionary character innovation that conventional art is proposed, research and development and the preparation that ultra-high molecular weight fibers carries out application product is substituted by ultra-high molecular weight polyethylene film or band, its core concept mainly comprises: will be collected or collected the single thread of twisting by ultra-high molecular weight polyethylene film or band, substitute traditional superhigh molecular weight polyethylene fibers, research and develop and prepare each kind fabric.
Wherein, as shown in Figure 1a, ultra-high molecular weight polyethylene film 101 is a kind of thin slices being become by ultrahigh molecular weight polyethylene, have one fixed width and thickness, and width is far longer than thickness.As shown in Figure 1 b, tapes of ultra high molecular weight polyethylene 102 independently can be prepared or can by the strip thin slice carrying out point cutting process before and after this film stretching and formed, and the width of band is less than the width of film, and thickness and film are quite or be greater than the thickness of film.
Ultra-high molecular weight polyethylene film provided by the invention or band, different from superhigh molecular weight polyethylene fibers, from gluedd joint the plane formed by many superhigh molecular weight polyethylene fibers also different, their remarkable difference is: ultra-high molecular weight polyethylene film provided by the invention or band itself have certain width and thickness, is a kind of overall structure not having binding site or cutting line.
The single thread that various embodiments of the present invention provide obtains based on ultra-high molecular weight polyethylene film or band.In described single thread preparation process, that ultra-high molecular weight polyethylene film or band are integrally processed, structural integrity is good, preparation technology is simple, eliminate the complicated technology that plurality of fibers silk is arranged respectively, the surface significantly reducing film or band produces the probability of burr, and also obviously the probability of the phenomenons such as fracture of wire, distortion, winding appears in reduction film or interior strips.During single thread carrying load ultra-high molecular weight polyethylene film or band collected, ultra-high molecular weight polyethylene film or band are overall stressed, make the intensity of this single thread higher, effectively improve rate of utilization of strength.Therefore, adopt the intensity of the single thread of ultra-high molecular weight polyethylene film or band, higher than the product adopting the superhigh molecular weight polyethylene fibers of same Denier to prepare, and the former cost is starkly lower than the latter.
The single thread that various embodiments of the present invention provide has the advantages such as structural integrity is good, intensity is high, rate of utilization of strength is high, production efficiency is high, processing cost is low, lightweight, surface density is little, flexible, and complete alternative traditional superhigh molecular weight polyethylene fibers preparing product is widely used in every field.Specifically, described single thread can be substituted superhigh molecular weight polyethylene fibers and prepares all kinds of high strength fabric by various embodiments of the present invention.In the preparation process of high strength fabric, it is the processing process carrying out fabric body based on single thread, tradition is carried out processing and is processed the fabric that obtains based on superhigh molecular weight polyethylene fibers relatively, the obtained fabric construction good integrity of various embodiments of the present invention, preparation technology is simple, production efficiency is high, intensity is high, rate of utilization of strength is high, lightweight, flexible.During fabric carrying load, each single thread is overall stressed, makes the intensity of fabric higher, effectively improves rate of utilization of strength.Therefore, the intensity of the single thread goods adopting described single thread to prepare, far away higher than the product prepared based on superhigh molecular weight polyethylene fibers adopting same Denier, and the former cost is starkly lower than the latter.
In various embodiments of the present invention, this high strength fabric can comprise fabric body self, also can comprise as the miscellaneous part such as protective layer, reinforcement; The method preparation that fabric body can adopt following each embodiment to provide, the preparation method of the miscellaneous part except fabric body can adopt related art to realize, and various embodiments of the present invention all do not limit this; In addition, single thread is previously prepared before can preparing prior to fabric body, or single thread can be prepared in fabric body preparation process, and various embodiments of the present invention also all do not limit this.
