Problems solved by technology

However, even this still cannot meet the needs of cutting resistance performance in practical applications
[0003] In order to meet the needs, products that use high-hardness fibers such as glass fibers or even steel wires to be blended with ultra-high molecular weight polyethylene fibers have been invented, and thickening or coating technologies have also been invented. These methods have indeed improved the fabric's durability. Cutting performance, but it also brings problems such as difficulties in post-processing and discomfort in taking, and the cost of products also increases significantly
Therefore, such products can only be barely applied in limited occasions

Embodiment 1-12

[0025] Embodiments 1-12 provide a kind of cutting-resistant ultra-high molecular weight polyethylene fiber respectively, and its preparation process refers to the parameters in Comparative Example 1, and the difference is that rod-shaped particles are also added during swelling, so that each rod-shaped particle accounts for the proportion of rod-shaped particles and powdery particles. The percentages of the total mass of UHMWPE are respectively: magnesium borate whiskers (the Mohs hardness is 6, the aspect ratio is about 10, and the diameter is about 10 microns) 3wt% (embodiment 1), magnesium borate whiskers (the Mohs hardness is 6 , aspect ratio is about 10, diameter is about 10 microns) 6wt% (embodiment 2), magnesium borate whisker (Mohs hardness is 6, aspect ratio is about 10, diameter is about 10 microns) 7wt% (implementation Example 3), magnesium borate whisker (Mohs hardness is 6, aspect ratio is about 2, diameter is about 10 microns) 7wt% (embodiment 4), magnesium borate...

Embodiment 13

[0027] The present embodiment provides a cut-resistant ultra-high molecular weight polyethylene fiber, and its preparation process refers to the parameters in Comparative Example 1. The ratio is about 20, the diameter is about 10 microns) and the total mass concentration of powdered UHMWPE is 8.3%, and the weight ratio of silicon dioxide and UHMWPE is 11:99.

Embodiment 14

[0029] This embodiment provides a cut-resistant ultra-high molecular weight polyethylene fiber, the process parameters of the preparation are basically the same as those in Example 8, the difference is that it adopts figure 1 The process flow shown and adopt as figure 2 The existing sheath-core type spinning group shown, obtains as image 3 The ultra-high molecular weight polyethylene fiber containing silica in the core layer shown in (a) (the total addition of silica in the skin layer and the core layer is about 11 wt%). The finished filaments prepared in this way can avoid white powder and equipment wear during post-processing. It is found that the finished filaments in the relaxed state sometimes have self-crimping and fluffy that can be observed, which may be due to the difference between the center of the core layer nozzle and the center of the cortex nozzle hole. Minor positional deviation, or due to the slight viscosity difference between the core spinning solution an...

Abstract

The invention relates to cutting-resistant ultra high molecular weight polyethylene fiber, a preparation method and application thereof. The cutting-resistant ultra high molecular weight polyethylene fiber is endless tow or / and short fiber in morphology; the matrix of the polyethylene fiber comprises rodlike particles; the Moh's hardness of each rodlike particle is of grade 3 and above (one with high hardness is preferred); the length-diameter ratio of each rodlike particle is greater than or equal to 2 micrometers; the diameter of each rodlike particle is smaller than 30 micrometers. By adopting the cutting-resistant ultra high molecular weight polyethylene fiber, the cutting resistance of high molecular weight polyethylene fiber and a fabric of the high molecular weight polyethylene fiber can be improved, the fiber has post processing properties prior to those of conventional cutting-resistant fiber of a same grade and fabrics of the conventional cutting-resistant fiber, and the cost can be lowered.

Description

technical field [0001] The invention relates to the field of fiber materials, and relates to a cut-resistant ultra-high molecular weight polyethylene fiber, a preparation method and an application thereof. Background technique [0002] Ultra-high molecular weight polyethylene (UHMWPE) fibers have the advantages of high weight-to-weight ratio, chemical corrosion resistance, excellent aging resistance, and low temperature resistance, so they are widely used in fields such as bulletproof and cutproof, sports equipment, marine engineering, and composite materials. Such as body armor, cut-resistant gloves, explosion-proof clothing, marine ropes, fishing lines, sports boats, sails, bicycles, packaging materials, etc. The reason why the ultra-high molecular weight polyethylene fiber has a high weight-to-weight ratio is due to the extended chain structure in the ultra-high molecular weight polyethylene fiber. Before the invention of the gel spinning method, conventional molecular w...
