Description
Technical Field
The invention belongs to the technical field of fiber treatment by using a composition containing unsaturated ether, and particularly relates to a polyvinyl alcohol water-soluble short fiber spinning oil and a preparation method thereof.
Background
The polyvinyl alcohol fiber is made from polyvinyl alcohol (PVA) as raw material through spinning, has the advantages of high strength, wear resistance, good moisture absorption and the like, has the performance similar to that of cotton, and is called as artificial cotton. The polyvinyl alcohol water-soluble short fiber not only has water-soluble temperature, strength and elongation at break within a certain range, but also is colorless and transparent after being dissolved in water, tasteless and nontoxic, can be naturally degraded in a short time under the action of sunlight, air, water and microorganisms, and is an environment-friendly fiber with biodegradability. According to the unique water solubility of the polyvinyl alcohol water-soluble fiber and the characteristics of high strength and good wear resistance of the polyvinyl alcohol water-soluble fiber, the polyvinyl alcohol water-soluble fiber is applied to a plurality of textile fields such as blending or companion spinning.
The polyvinyl alcohol water-soluble short fiber is used as a chemical fiber, is different from a natural fiber with the surface covered with a lubricant such as grease and the like, and has a great difference with most chemical fibers with better hydrophobicity. The polyvinyl alcohol water-soluble short fiber has more hydroxyl groups with stronger hydrophilicity and better hygroscopicity. Therefore, in order to ensure that the polyvinyl alcohol water-soluble short fibers can be smoothly processed and improve the spinnability in the processing process after spinning, a spinning oil agent is required to be used in the production process, so that static electricity is reduced, tow abrasion is prevented, cohesive force is controlled, and the fibers are endowed with good convergence, smoothness and dispersibility so as to meet the requirements of subsequent procedures and downstream customer production and processing.
However, the existing polyvinyl alcohol water-soluble short fiber spinning oil agent has unstable performance, is easy to delaminate after being placed for 1-2 months, and even more, the delamination phenomenon occurs after being placed for 1-2 weeks; the existing polyvinyl alcohol water-soluble short fiber spinning oil agent has large crude oil smell and influences the health of operators, and the phenomena of powdery mildew falling, poor after-processing net-forming cohesion of fiber products, poor carding and antistatic performance and the like easily occur in the after-spinning processing process, particularly poor adaptability to environment temperature and humidity, poor production winding forming, low high-quality product rate, serious corrosion phenomenon and great influence on the stable production of after-spinning processing. According to statistics of customer complaints in 2014-2016, the mass problems of post-processing caused by oil factors are respectively 31% of whiting, 34% of poor spinnability and 22% of low equal-grade rate. Therefore, it is necessary to develop a novel polyvinyl alcohol water-soluble short fiber spinning oil agent to improve the subsequent processing application performance.
