All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.
As shown in fig. 1, a method for preparing a jacket made of a cut-resistant antistatic fabric comprises the following steps:
S1, adding ultra-high molecular weight polyethylene powder into a solvent, and carrying out swelling treatment to obtain a swelling solution with the mass concentration of 6-10%;
s2, taking the metal wire as a central fiber, taking the swelling liquid in the step S1 as an outer wrapping fiber, coaxially spinning, and cooling the fiber sprayed from a spinning port in an alumina solution for 1-2h to obtain a primary treatment fiber;
s3, soaking the primary treatment fiber in the S2 in an antistatic solution to obtain a secondary treatment fiber;
S4, weaving the secondary treatment fibers in the S3 to obtain a cut-resistant antistatic fabric, and combining the cut-resistant antistatic fabric with the outer layer of the jacket to obtain the jacket made of the cut-resistant antistatic fabric.
After coaxial spinning is carried out by using ultra-high molecular weight polyethylene and metal wires, the fiber obtained by spinning is placed in an alumina solution for cooling, and the cooled fiber is soaked in an antistatic solution, and the soaked fiber is woven into a fabric for being combined with an outer layer of the jacket, so that the antistatic coating and the ultra-high molecular weight polyethylene can form more tight connection, the compactness of the ultra-high molecular weight polyethylene and the antistatic coating is improved, and the problem that the antistatic effect in the ultra-high molecular weight polyethylene jacket fabric in the prior art is not durable is solved.
The molecular weight of the ultra-high molecular weight polyethylene powder in the S1 is 100-500 ten thousand, the swelling treatment temperature is 65-95 ℃, and the swelling time is 2-4h. The higher the molecular weight of the ultra-high molecular weight polyethylene, the longer its molecular chain, which generally means better mechanical properties, including higher tensile strength and abrasion resistance. Thus, selecting a molecular weight range of 100-500 ten thousand ensures that the fiber has a high cut resistance. Proper swelling treatment helps to increase the compatibility of the polyethylene powder with the solvent, thereby forming a more uniform, denser fiber structure during the spinning process. The structure can improve the cutting resistance of the fabric.
Higher molecular weights can increase the crystallinity of the polyethylene, thereby improving its electrical insulation properties. However, in order to achieve an antistatic effect, an antistatic coating needs to be added to the fabric. The combination of high molecular weight polyethylene with an antistatic coating may provide better antistatic properties. The proper swelling treatment temperature and time help control the degree of dissolution of the polyethylene powder, thereby affecting the surface properties and pore structure of the fiber. This helps the antistatic coating adhere better to the fiber surface, improving antistatic properties. The swelling treatment can alter the surface properties of the polyethylene powder to make it easier to bond with the antistatic coating. Proper swelling treatment can improve the surface roughness of the fiber, increase the contact area with the coating, and further improve the binding force between the two.
And S2, the metal wire is made of one or more of silver, copper and ferric oxide, and the fineness of the metal wire is 2-4D. The metal wire has higher strength and cutting resistance, in particular to iron oxide and stainless steel materials, and the addition of the metal wire can obviously improve the overall cutting resistance of the fabric. The fineness of the metal wires is smaller, so that the fabric is more compact, and the cutting resistance of the fabric is improved while the softness of the fabric is maintained.
The silver silk thread and the ferric oxide silk thread are twisted to be used as central fibers, the number of the silver silk thread and the ferric oxide silk thread in one metal silk thread is respectively 1-2F and 2-4F, and the twist is 40-50 twists/10 cm. The metal material has good conductivity, can effectively guide static electricity to the ground, reduces accumulation of static electricity, and improves antistatic performance of the fabric. The metal wires form a conductive network in the fabric, which is helpful for rapidly dispersing and neutralizing static electricity and reducing the influence of the static electricity on the wearer.
The fineness of the fiber sprayed out of the spinning port in the S2 is 6-10D, and the coaxial spinning method is one of electrostatic spinning and wet spinning. Finer fibers (6-10D) can provide finer, more uniform weave structures, thereby increasing the overall strength and cut resistance of the fabric. The metal wires (such as silver, copper and ferric oxide) have good conductivity and can provide an effective electrostatic discharge path, so that the antistatic performance of the fabric is enhanced.
The mass concentration of the alumina solution in the S2 is 10-15%, and the particle diameter of the alumina is 200-400nm. The alumina particles form a wear-resistant layer on the surface of the fiber, so that the hardness and the cutting resistance of the fiber are improved. The alumina particles have high hardness, can disperse external force, and reduce the damage of the fiber when the fiber is subjected to cutting force. The alumina has good conductivity, can be used as a charge transmission medium, and improves the antistatic performance of the fabric. The addition of particles may increase the friction between the fibers, promote charge transfer and neutralization, and thus reduce static buildup. The alumina particles form roughness on the surface of the fiber, so that the contact area between the fiber and the antistatic coating is increased, and the adhesive force of the coating is improved. The alumina particles may act as physical anchor points, helping the antistatic coating to adhere better to the ultra high molecular weight polyethylene fibers. The alumina particles can act as a support structure between the ultra-high molecular weight polyethylene layer and the antistatic coating so that mechanical strength is maintained and a connection between the antistatic coating and the ultra-high molecular weight polyethylene layer can be maintained when the antistatic coating is cut.
And (2) carrying out ultrasonic treatment in the cooling process in the step (S2), wherein the frequency of the ultrasonic treatment is 40-60kHz. The ultrasonic vibration energy promotes the uniform distribution of alumina particles in the fiber, and improves the compactness of the fiber structure, thereby enhancing the cutting resistance of the fiber. The ultrasonic treatment can generate fine mechanical acting force on the surface of the fiber, increase the roughness of the surface of the fiber and help to improve the adhesive force and the compactness between the ultra-high molecular weight polyethylene fiber and the antistatic coating. The ultrasonic vibration is helpful for the combination between the metal wire and the ultra-high molecular weight polyethylene fiber, the metal wire is used as a conductive path, and the tight combination of the metal wire and the fiber can improve the antistatic performance of the fabric. The ultrasonic vibration can promote the combination of alumina particles and fibers to form a firmer interface, which is helpful for improving the wear resistance and cutting resistance of the fibers. The mode that the spun fibers are soaked in the alumina particles enables the ultra-high molecular weight polyethylene layer to be combined with the alumina particles through cold and hot changes, and the combination property of the ultra-high molecular weight polyethylene layer and the alumina particles is enhanced.
The antistatic solution in the S3 is one of polyethylene glycol solution, alkyl sodium sulfonate solution and fatty amine ethoxy ether, and the mass concentration of the antistatic solution is 3-5%. These antistatic solutions can improve antistatic properties by reducing static charge build-up on the fabric surface. The addition of antistatic agents aids in the conduction and dispersion of charges, thereby reducing the potential harm of static electricity to humans and equipment. The addition of the antistatic solution helps to improve the adhesion between the ultra-high molecular weight polyethylene fibers and the antistatic coating, forming a more stable bond.
And S4, spinning the secondary treatment fiber to be used as warp yarn, and using the aramid yarn as weft yarn, wherein the weaving pattern is plain weave. The aramid yarn has high strength and cutting resistance, and the overall cutting resistance of the fabric can be remarkably improved by taking the aramid yarn as the weft yarn. The plain weave mode ensures that the interweaving points of the warp and weft yarns are more, and the structure can better disperse and absorb the cutting force, thereby improving the cutting resistance of the fabric. The secondary treatment fiber is treated by the antistatic solution, and can form a uniform antistatic network in the whole fabric as warp yarns. The aramid yarn has good conductivity, and can further improve the antistatic property of the fabric by combining with the treated warp yarns.
The plain weave mode is favorable for the uniform distribution of the antistatic coating among the fibers and improves the adhesive force of the coating. The tight interweaving of the warp and weft yarns can increase the contact area between the coating and the ultra-high molecular weight polyethylene fibers, thereby improving the binding force between the coating and the ultra-high molecular weight polyethylene fibers.
And S4, the mode of combining the cut-resistant antistatic fabric and the outer layer of the jacket is one of sewing or bonding. The sewing method tightly combines the fabric and the outer layer through the suture, and the tension and strength of the suture can further improve the cutting resistance of the whole structure. Bonding methods by using specific adhesives, a strong bond of the facing to the outer layer can be achieved without adding additional sutures, the elasticity and toughness of the adhesive helping to disperse and absorb the cutting forces.

Table cutting resistance and antistatic property test data for examples one to thirteen and comparative examples one to two
As can be seen from Table I, the cut resistance levels of examples one to thirteen are not smaller than those of comparative example one, the resistivities of examples one to thirteen are smaller than those of comparative example one, and the preparation method of the jacket made of the cut-resistant antistatic fabric has advantages.
In the first to fifth embodiments, as the concentration of the ultra-high molecular weight polyethylene in the swelling solution gradually increases, the cutting resistance and antistatic performance of the jacket are increased and then reduced, because the molecular chains of the ultra-high molecular weight polyethylene are more closely arranged as the concentration of the ultra-high molecular weight polyethylene in the swelling solution increases, the strength and toughness of the fibers are increased, thereby improving the cutting resistance, the too high concentration reduces the flexibility and impact resistance of the fabric, and affects the uniformity of the fibers and the bonding force between the fibers, so that the fibers are easier to break when subjected to cutting force, and the cutting resistance is reduced, while the silver wires and the oxidized iron wires are used as central fibers, the metal wires provide conductive paths, and the ultra-high molecular weight polyethylene can form a good fiber structure, thereby facilitating the uniform distribution of the silver wires and the oxidized iron wires in the fabric, so that a more effective conductive network is constructed, thereby improving the antistatic performance of the fabric, and when the concentration is too high, causing the metal wires to be excessively wrapped, thereby limiting the contact between the metal wires and the flow of electrons, which can reduce the antistatic performance of the fabric. The preferred embodiment is embodiment three.
In the third and the ninth embodiments, as the mass concentration of the alumina solution is gradually increased, the cutting resistance and the antistatic performance of the jacket are increased and then reduced, because alumina can play a role in enhancing the bonding force between fibers and the overall strength of the fabric, alumina particles can be uniformly distributed on the surfaces of the fibers or among the fibers to form an effective reinforcing phase, thereby improving the cutting resistance of the fabric, but when the alumina concentration is too high, the flexibility of the fibers is reduced, so that the fibers are easier to break when the alumina concentration is too high, the uniformity of the fibers and the bonding force between the fibers are influenced, the weakness of the overall structure is caused, and the cutting resistance is reduced, the alumina particles themselves can have conductivity, the conductive performance of the fabric can be improved to a certain extent, thereby reducing the accumulation of static electricity, and the addition of the alumina particles can be helpful for constructing a more complex conductive network, further improving the antistatic performance of the fabric, but the too high alumina concentration can also influence the construction of the conductive network on the surface of the fabric. When the alumina particles are too large, they may aggregate with each other to form larger particle clusters, thereby destroying the otherwise uniform conductive network structure. This may lead to a decrease in the conductivity of the fabric, which in turn reduces the antistatic properties. The preferred embodiment is embodiment seven.
In the seventh embodiment and the tenth to thirteenth embodiments, as the twist in the metal wire is gradually improved, the cutting resistance and the antistatic performance of the jacket are increased and then reduced, because increasing the twist of the metal wire can enhance the strength and the abrasion resistance of the wire, thereby reducing the breakage of the fiber during cutting, improving the cutting resistance of the jacket fabric, but too high twist can stiffen the fiber, reduce the flexibility and the elasticity thereof, thereby affecting the overall cutting resistance of the jacket fabric, and increasing the twist of the metal wire can better disperse the fiber in the fabric to form more conductive channels, thereby improving the antistatic performance of the jacket, but when the twist is too high, the tight interweaving between the metal wires can obstruct the dissipation of the static charges, resulting in static accumulation. The preferred embodiment is embodiment eleven.
In the embodiment eleven and the comparative example II, the center fiber of the comparative example II is a silver wire, the cutting resistance and the antistatic performance of the embodiment eleven are both greater than those of the comparative example II, because the silver wire has good physical properties, but the strength is not enough to bear the cutting force of the jacket alone in a complex environment, the iron oxide wire has higher strength and hardness, after being twisted with the silver wire, the composite fiber with higher strength can be formed, the composite fiber can better resist the external cutting force, thereby improving the cutting resistance of the jacket, the twisted silver wire and the iron oxide wire can form a more compact fiber structure, the structure is helpful for dispersing and resisting the cutting force, further enhancing the cutting resistance of the jacket, and the twisted fiber can promote the combination with the ultra-high molecular weight polyethylene coating, the twisted silver wire and the iron oxide wire can form a charge balance system, and help reduce the accumulation and release of static electricity, thereby improving the antistatic performance of the jacket, and improving the conductivity difference between the silver wire and the aluminum oxide wire and the conductive network. The preferred embodiment is embodiment eleven.
