Abstract
The invention provides high-performance polyethylene fibers and applications of the high-performance polyethylene fibers in anti-cutting ropes, and relates to the technical field of rope production. According to the present invention, the polyethylene fibers adopt ethylidene as a repeated unit, and contain fiber-state polyethylene with a weight average molecular weight (Mw) of 40000-240000, and a weight average molecular weight to number average molecular weight (Mn) ratio (Mw/Mn) of less than or equal to 4.0, and the gel fraction in the fibers is 100-10000 ppm. According to the present invention, with the application of the high-performance polyethylene fibers in anti-cutting rope knitting, the high-performance polyethylene fibers has strong tensile resistance, such that high thermal insulation and cutting resistance are provided when the high-performance polyethylene fibers are adopted as the main material of the rope, and light weight, high strength, cutting resistance, wear resistance and other special market requirements of the rope can be met.
Description
Technical field
The present invention relates to the production technical field of rope.
Background technology
At present, rope uses chemical fibre as cutting resistance material usually, is used for greatly needing wear-resisting, cut resistant protection with the rope that these fibers etc. weave.
So, as imparting cutting resistance function, designed the rope yarn etc. be made up of the spun yarn of the high strength fibres such as aramid fibre.But, from the viewpoint of wear-resisting or durability, can't be satisfactory.In addition, as other method, attempt by metal fibre and chemical fibre are used for improving cutting resistance, but exist and cause because mixing metal fibre the problem that feel is hardening, affect flexibility.
In addition, as the invention solving problem as above, motion has the Knitted rope using and have the polyethylene fiber of high elastic modulus.But, because the elastic modelling quantity of fiber is too high, therefore, not only Boardy Feeling, and in using the cutting resistance of anti-cutting performance test to measure, can only 3.6 be obtained as exponential quantity is the highest.In addition, also there is the problem that operability declines, that is, because raising intensity and elastic modelling quantity improve cutting resistance, therefore, thermal conductivity also uprises, in addition, also there are the following problems: owing to using the polyvinyl resin of high molecular, therefore, can not draw speed be improved, thus the productivity ratio of polyvinyl resin fiber can not be improved; Or easily there is the spinning unstability such as draw resonance, form strand irregular, unstable at aft-loaded airfoil operation generating process.
Summary of the invention
The object of the invention is to propose a kind of high-performance polyethylene fibres may given birth to anti-cutting rope and produce.
Polyethylene fiber of the present invention take ethylidene as the polyethylene fiber with repetitive ethylidene, the weight average molecular weight (Mw) comprising fiber condition is 40,000-240,000, the ratio (Mw/Mn) of weight average molecular weight and number-average molecular weight (Mn) is the polyethylene of less than 4.0, gel fraction in fiber is 100ppm ~ 10,000ppm.
Another object of the present invention is the purposes proposing above high-performance polyethylene fibres: for the braiding of anti-cutting rope.
The polyethylene fiber self proposed due to the present invention has very strong pull resistance, so when it can be used as the main material of rope, tool height heat insulating ability and cutting resistance, can to meet rope quality gently, high-tenacity, anti-cutting, the niche market such as wear-resistant requirement.
Detailed description of the invention
High-performance polyethylene is formed by chemical synthesis process, repetitive is essentially ethylidene, the weight average molecular weight (Mw) comprising fiber condition is 40,000 ~ 240,000, the ratio (Mw/Mn) of weight average molecular weight and number-average molecular weight (Mn) is the polyethylene of less than 4.0, gel fraction in fiber is 100ppm ~ 10,000ppm.
By melting rear spinning process, form high-performance polyethylene fibres.
This fiber becomes stock to produce again.
High-performance polyethylene fibres there is is to be woven into anti-cutting rope one-tenth stock with mechanical technology.
The anti-cutting performance of this rope is better than mill run, and flexibility is moderate, good hand touch.
Claims (2)
1. a high-performance polyethylene fibres, it is characterized in that, repetitive is essentially ethylidene, the weight average molecular weight (Mw) comprising fiber condition is 40,000 ~ 240,000, the ratio (Mw/Mn) of weight average molecular weight and number-average molecular weight (Mn) is the polyethylene of less than 4.0, and the gel fraction in fiber is 100ppm ~ 10,000ppm.
2. polyethylene fiber as claimed in claim 1 is in the application on anti-cutting rope, it is characterized in that: the braiding carrying out anti-cutting rope with polyethylene fiber.
