Description
Technical Field
The invention belongs to the technical field of chemical fiber processing, and particularly relates to a preparation method and application of PE cool fiber.
Background
With the improvement of the quality of life, people have higher and higher requirements on clothes, and pursue comfort while pursuing beauty. Especially in summer, a human body is easy to sweat, and the fabric is easy to stick to the human body, so that people feel wet and greasy, and therefore the textile fabric with the characteristics of moisture absorption and sweat releasing is highly advocated. At present, the fabric with the best moisture absorption and sweat releasing effects belongs to a one-way moisture-conducting fabric, and the principle of the fabric is realized through different moisture absorption of the inner layer and the outer layer of the fabric, namely the inner layer of the fabric is hydrophobic, the outer layer of the fabric is hydrophilic, sweat is adsorbed to the outer surface layer of the fabric to volatilize rapidly under the action of a differential capillary effect, and external water molecules cannot permeate into the inner layer of the fabric, so that the control effect of one-way moisture conduction is achieved, and the wearing comfort of the garment can be improved. Polypropylene is often used as a hydrophobic layer of a unidirectional moisture wicking fabric due to its excellent hydrophobic properties. Polyethylene fiber (PE) has good hydrophobicity as well, and also has higher heat-conducting property compared with polypropylene fiber, if the polyethylene fiber (PE) is applied to a unidirectional moisture-conducting fabric, moisture can be conducted quickly, heat can be conducted quickly, dryness of the fabric can be met, and meanwhile the fabric has cooling sensitivity. At present, polyethylene materials are widely applied to pipes, bars, plastic films and the like, and the number of fiber products is very small, so that the polyethylene has great development prospect and research and development value in the application of moisture-conducting fabrics.
At present, the industrial production method of polyethylene fiber mainly adopts a gel spinning method, and an organic solvent is required to be added in the production process of the method, and solvent extraction is required to be carried out subsequently. Although the fiber obtained by the method has high strength, the process is complex, the production cost is high, the product price is expensive, and the method is not environment-friendly. Based on the concepts of simplifying the process, saving the cost and protecting the environment, the method for preparing the polyethylene by replacing the gel spinning method is very necessary to be found. Compared with gel spinning, the melt spinning does not need links such as adding solvents, extracting solvents and the like, products can be prepared by using the existing polyester spinning equipment, and the requirements of simple working procedures, simple equipment, low cost and environmental protection are met. At present, the related research and application of polyethylene fiber melt spinning are few, and in the prior art, the polyethylene fiber obtained by melt spinning has low strength and poor fiber forming property in the spinning process. Because the melting point of PE is very low and is only 130 ℃, the control of the technology is very strict when melt spinning is carried out. In order to make the product meet the requirement of weaving strength, the polyethylene is modified mainly by means of adding an auxiliary agent.
CN 104711697A discloses a polyethylene fiber and a preparation method thereof, wherein a siloxane or amide or stearate lubricant is added as a modifier of high-density polyethylene, the mixture is extruded and melted by a double screw, the melting temperature is controlled at 130 ℃ and 330 ℃, the filament-drawing speed is 0.2-5m/min, and finally the polyethylene fiber with the strength of 7-20g/d and the elongation at break of 3-10% is obtained. CN 102002769A discloses a preparation method of ultra-high molecular weight polyethylene fiber, which comprises the steps of firstly adding POE polyolefin elastomer, PE foaming agent, ethylene propylene diene monomer and other substances to modify low-density polyethylene, then compounding with ultra-high molecular weight polyethylene resin, and obtaining the polyethylene fiber with the strength of 15-25cN/dtex and the elongation at break of 5-8% through melt spinning. CN 108588884A discloses a preparation method of high molecular weight polyethylene fiber by melt spinning, which comprises adding kaolin modified high molecular weight polyethylene, extruding into filaments by a screw, controlling the melting temperature at 165-255 ℃ and the drawing speed at 75-85 r/min. The prior technical scheme needs to improve the fiber forming property of the polyethylene melt and improve the fiber strength by other auxiliary agents, and the selected auxiliary agents are high in price, and the problems that the auxiliary agents are not uniformly dispersed and have more broken filaments and the like can also occur in the processing process.
