Description
Technical Field
The invention belongs to the technical field of modified synthetic fibers, and relates to a preparation method of a modified thermoplastic polyurethane elastomer multifilament with excellent elongation at break and elastic recovery rate, which is environment-friendly and pollution-free.
Background
The elastic fiber fabric is attached to a human body, has soft and smooth hand feeling, and gives good comfort and excellent aesthetic feeling to the garment fabric. Spandex is the most widely used, commercially mature elastic fiber. In recent years, the application of spandex is becoming wider, and the addition amount of spandex in various novel fabrics and functional clothes is becoming higher and higher, and is varied from 3% to 30%. The spandex has large elongation and high elastic recovery rate, and the elasticity of the fabric can be obviously improved by adding a small amount of spandex, so the spandex is named as 'monosodium glutamate' in the textile.
At present, there are 4 production methods of spandex, namely a dry spinning method, a wet spinning method, a chemical reaction method and a melt spinning method. Wet and chemical reaction processes have been essentially eliminated and dry spinning is currently used. The dry spinning spandex has excellent performance, but the investment of production equipment is large, and the production cost is high (the raw material cost is low); especially, a large amount of organic solvents (such as DMF, DMAC and the like) are used in the dry spinning process, the toxic solvents are easy to remain on the surface or inside of the fiber, the direct contact can cause damage to the liver, and the dry spinning process is not suitable for manufacturing fabrics which are in direct contact with the skin; the three wastes of dry spinning are serious, and serious pollution to the environment is caused; in addition, the traditional spandex is not recyclable, and because the general spandex is thermosetting fiber, the recycling difficulty is high, and along with the expansion of the application range of the spandex, a large amount of spandex fabrics are inevitably wasted, and huge pollution and waste are caused.
In order to solve the above problems, thermoplastic polyurethane elastomer fibers employing a melt spinning process have attracted widespread attention in the textile industry. The melt spinning equipment investment is small, the process is simple and stable, the yield is high, the production cost is low, the melt spinning does not use an organic solvent, the production process is environment-friendly and pollution-free, and the prepared thermoplastic polyurethane elastomer fiber has no harm to human bodies and good recovery performance.
Melt spun thermoplastic polyurethane elastomer yarns have become the most potential spandex replacement. However, since the thermoplastic polyurethane elastomer is very sensitive to shearing action, degradation occurs with an increase in shearing stress or frequency during the melt heating process, the melt viscosity drops sharply, the fiber cannot be formed smoothly, it is in a sparse fluid state, and the yarn is extremely easily broken under the action of winding tension when the multifilament is spun. These problems greatly limit the production and use of thermoplastic polyurethane elastomer multifilament yarns.
Disclosure of Invention
In view of the problems in the prior art, it is an object of the present invention to provide a modified thermoplastic polyurethane elastomer multifilament yarn having good elongation at break and elastic recovery.
A second object of the present invention is to provide a process for producing the above-mentioned modified thermoplastic polyurethane elastomer multifilament yarn, which can satisfy the process requirements for melt spinning the multifilament yarn.
In order to achieve the above purpose, the invention is realized by adopting the following technical scheme:
the polyborosiloxane is a novel high molecular material of element modified polysiloxane, and is a polymer obtained by introducing boron atoms into a polysiloxane siloxane skeleton. The boron atom in the Si-O-B structure in the polyborosiloxane molecular chain can form a B-O electronic bridge pair with the oxygen atom in the adjacent chain, and the electronic bridge pair is a dynamically variable physical crosslinking and is in a dynamic process of continuous dissociation and reformation. It therefore has a particular rheology and good viscoelasticity.
The invention adopts the melt blending method to modify the thermoplastic polyurethane elastomer by the polyborosiloxane, improves the shearing resistance of the thermoplastic polyurethane elastomer, enhances the melt strength of the thermoplastic polyurethane elastomer, and enables the thermoplastic polyurethane elastomer to be smoothly molded and wound, thereby improving the spinnability of the thermoplastic polyurethane elastomer. And the coupling agent is added to improve the compatibility of the polyborosiloxane and the thermoplastic polyurethane elastomer, improve the blending dispersion state of the polyborosiloxane and the thermoplastic polyurethane elastomer, and meanwhile, the plasticizer is added to increase the melt fluidity and improve the manufacturability of the melt spinning multifilament. Then, melt spinning is performed to obtain a modified thermoplastic polyurethane elastomer multifilament yarn. The scheme is carried out sequentially according to the following steps:
step one: weighing polyborosiloxane, a coupling agent and a plasticizer according to a certain mass ratio, and uniformly stirring and mixing at a certain temperature;
step two: taking the mixture obtained in the step one, carrying out melt blending with a thermoplastic polyurethane elastomer according to a certain proportion, and granulating;
step three: and (3) taking the modified thermoplastic polyurethane elastomer particles obtained in the step (II) to carry out vacuum drying at a certain temperature for a certain time.
Step four: and (3) taking the dried thermoplastic polyurethane elastomer particles in the step (III) to carry out melt spinning under certain process conditions, so as to obtain the modified thermoplastic polyurethane elastomer multifilament.
Preferably, the molar ratio of silicon atoms to boron atoms in the polyborosiloxane described in step one is 15.1:1 to 5.3:1.
Preferably, the coupling agent described in step one includes, but is not limited to, gamma-aminopropyl trimethoxysilane, gamma-methacryloxy functional alkoxysilanes, and the like.
Preferably, the mass ratio of the coupling agent to the polyborosiloxane in the first step is 2:45-1:18.
Preferably, the plasticizer in step one includes, but is not limited to, dimethoxyethylene phthalate, triethylene glycol dipelargonate.
Preferably, the mass ratio of the plasticizer to the polyborosiloxane in the step one is 1:18-1:15.
Preferably, the ratio of the polyborosiloxane to the thermoplastic polyurethane elastomer in the second step is 1:10.
Preferably, in the fourth step, the spinning speed is 400-750 m/min.
Compared with the prior art, the invention blends and modifies the polyborosiloxane and the thermoplastic polyurethane elastomer, and under the action of the coupling agent, the polyborosiloxane and the thermoplastic polyurethane elastomer can be uniformly mixed and dispersed, so that the interfacial binding force of the polyborosiloxane and the thermoplastic polyurethane elastomer in the blending material is improved, and the mechanical property of the blending material is improved. The use of the plasticizer improves the flowability of the polyborosiloxane during the processing process, thereby improving the spinnability of the blend material. Meanwhile, as the shear viscosity platform of the polyborosiloxane is extremely wide, the polyborosiloxane has stronger shear thinning resistance, and the combination of the polyborosiloxane and the polyborosiloxane improves the melt strength of the modified thermoplastic polyurethane elastomer and improves the spinnability of the modified thermoplastic polyurethane elastomer.
The specific principle is as follows: at the spinning temperature, the viscosity of the polyborosiloxane is basically kept stable along with the improvement of the shearing strength, the polyborosiloxane is uniformly dispersed in the thermoplastic polyurethane elastomer matrix, and the polyborosiloxane and the thermoplastic polyurethane elastomer matrix are very firmly combined, so that the influence of shearing thinning on fiber molding during the melt extrusion of the thermoplastic polyurethane elastomer is overcome to a great extent, the melt strength is improved, the formability of the thermoplastic polyurethane elastomer fiber is greatly improved, and the filament breakage phenomenon during the winding process is avoided.
