Abstract
In a method for producing seams on webbings for technical purposes, in particular on lifting straps or lashing straps for securing cargo during transport, a sewing thread is used to produce the seam, the fine strength of said sewing thread being significantly greater than the fine strength of the fibrous material or yarn from which the webbing is produced. In this way, the binding load of a webbing having a seam is increased.
Description
The present invention relates to a kind of method that is used for production seam on belt, especially when transportation, be used to protect the lifting belt or the binding belt of load with engineering significance.
Belt with engineering significance is produced from the yarn that is made of chemical fibre usually.Usually use the silk thread that constitutes by polyamide (PA 66), polyester (PES) or polypropylene (PP), this silk thread ability temperature and fast light, ageing-resistant, and this silk thread has the fibre strength of 60cN/tex at least.Joint for example being used for the integrated endless sling of accessory, is sewn, and wherein, planar section is interconnected by a plurality of sutures axial and/or that laterally move, and belt part to be joined in this planar section is overlapped.Here, be used as sewing thread usually with the identical fibrous material that constitutes belt and use, therefore obtain identical physics and chemical stability.Especially for the application of having relatively high expectations,, also strapping and sewing thread have been stipulated identical fibre strength for example for the lifting belt.
The tension test that has a belt of seam illustrates that its load limit is by the ultimate load decision of seam, because it is significantly less than the ultimate load of belt itself.
The objective of the invention is to, propose a kind of method that is used for production seam on belt, this method has realized the raising of the intensity and the ultimate load of seam.
In order to realize such purpose, according to the present invention, sewing thread is used to the production of seam, and the fibre strength of this sewing thread is higher than the fibre strength of the fibrous material or the yarn that are used to produce this belt significantly.
The present invention is based on such discovery, promptly in the fibre strength (Feinfestigkeit) of the sewing thread that uses during significantly greater than the fibre strength of belt yarn, when for example being its twice, the load-bearing capacity of seam is improved significantly, so the load limit that the result is provided with the belt of seam is improved significantly.Find that in addition the remarkable higher fibre strength of sewing thread does not have negative effect to the intensity of belt and other operating characteristic.In addition, the test explanation, by using sewing thread, the sewing thread of especially higher than the fibre strength of belt fibre strength can be realized the joint strength identical or higher with the intensity of belt.
Especially favourable result realizes that this sewing thread is made of the fibrous material of Dyneema brand in having the belt that is made of polyester of sewing thread.This is a kind of high-intensity fibrous material, this fibrous material be the linear polyethylene by high molecular weight constitute by the fiber of high elongation.High molal weight refers to every mole 400 at least here, the average molar mass of 000g.Linear polyethylene refers to that per 100 carbon atoms have and is less than one side chain, and preferred per 300 carbon atoms have and are less than one side chain.In addition, polyethylene can comprise other alkene of one or more and the polyethylene copolymerization of maximum 5Mol-%, as propylene, butylene, amylene, 4-methylpentene, octene.
Especially advantageously, when polyethylene fiber was used to produce sewing thread, this polyethylene fiber was made of the filament that is produced in the gel spinning process, as described in GB-A-2042414 and the GB-A-2051667.This process generally includes produces the polyolefin solution with high inherent viscosity, solution spray is being become filament surpassing under the temperature of solution temperature, cools off filament being lower than under the temperature that forms gel, and remove desolvate during or the filament that stretches afterwards.
The intensity that the seam of producing according to method of the present invention for identity basis can realize on the belt of fibre strength that constitute, fiber for 60cN/tex, thickness 1.8mm and width 45mm at least by the polyester multifilament yarn, belt is configured to ring, and free leash end is sewn by means of the suture that the zigzag with respect to the axioversion of belt moves on the strap length of 80mm.First kind of sample use fibre strength as polyester-multifilament yarn of 60cN/tex as sewing thread, and second kind of sample uses fibre strength that the fiber by the Dyneema brand of DSM High Performance Fibers B.V. company the constitutes yarn as 236cN/tex.The ultimate load that draws first kind of sample in continuous test is 19602N, and the ultimate load of second kind of sample is 27291N.
Two kinds of other tests utilize identical belt and identical sewing thread to implement, but wherein, the suture that ring only moves by means of 12 zigzag on the axial length of 40mm carries out belt and sews up.Here, the ultimate load that draws in the sample that the sewing thread that is made of polyester is sewed up is 24226N, and the ultimate load that draws in the sample that the sewing thread that is made of Dyneema is sewed up is 28647N.
The result shows, when suture was made of the sewing thread than the intensity of high several times of belt line according to the present invention, the ultimate load that has the belt of suture can be improved significantly.Therefore, the bearing capacity of belt is utilized better.Correspondingly can use thinner and therefore lighter belt to the loading condition that provides.
Claims (3)
1. be used for the method with engineering significance of production seam on belt, it is characterized in that, sewing thread is used to sew up, and the fibre strength of this sewing thread is improved significantly, is the twice of fibre strength that is used to produce the fibrous material of this belt especially at least.
2. according to the described method of claim 1, it is characterized in that the fibre strength of sewing thread is four times of fibre strength of belt fibres material at least.
3. according to each described method in the aforementioned claim, it is characterized in that sewing thread is by being made by the bigger linear polyethylene fiber of the molal weight of high elongation.
