Problems solved by technology

For example, the triangular fiber has a flash effect; the five-leaf fiber has a fat-like luster, has a good hand feeling, and is anti-pilling; the hollow fiber has a cavity inside, low density, good warmth retention, and has certain hygroscopicity. However, the hollow fiber In the process of post-processing, it is easy to cause problems such as fluffing and fiber fibrillation. As consumers have higher and higher environmental protection requirements for clothing, chemical fibers, especially polyester, are modified in the preparation process, so that the polyester fiber can be reduced. Chemical treatment in the fabric preparation process is becoming more and more important
[0005] The patent application number is 2112100534033, and the patent name is a hollow polyester fiber production method with composite functions. It provides a hollow patent with certain hygroscopic characteristics. The main preparation steps are relatively complicated and industrialization is difficult to achieve. During the yarn process, the fibers are prone to burrs and static electricity, resulting in end breaks and flying flowers, which affect product quality
[0006] The patent application number is 2013102627501, and the patent name is hydrophilic moisture-absorbing and sweat-wicking polyester fiber and its preparation method. It is mainly to first add some soluble additive substances to the polyester fiber, and finally in the post-treatment process, by adding acid or The alkali method dissolves the added additives, thereby changing the microstructure of the fiber to achieve the purpose of moisture absorption. This method is likely to cause a decrease in the strength of the polyester fiber, and at the same time increase the difficulty of post-processing and pollute the environment.

Abstract

The invention provides a negative oxygen ion health care function polyester fiber. The fracture intensity of the negative oxygen ion polyester fiber is greater than or equal to 6.35cN / dtex; the breakelongation is 25.2 to 27.8 percent; the dry heat shrinkage rate is less than or equal to 8.5 percent; the crimping rate is less than or equal to 3.5 percent; the moisture regain rate is greater than or equal to 1.5 percent. The negative ion generation quantity of the negative oxygen ion health care function polyester fiber is greater than or equal to 1850 / cm<3>. The invention also provides a preparation method of the negative oxygen ion health care function polyester fiber. The method comprises the steps of preparing tourmaline nanometer powder, preparing a tourmaline-cellulose function film,preparing tourmaline master batch, and preparing modified polyester slices. By using a special method of improving the hygroscopicity of the polyester fiber, the contact probability of the tourmalineparticles inside the fiber with water molecules can be increased; the negative oxygen ion release capability of the tourmaline is greatly improved; meanwhile, the spinning capability of the polyesterfiber can be greatly improved.

Description

technical field [0001] The invention relates to a polyester fiber and a preparation method thereof, in particular to a polyester fiber with a negative oxygen ion health care function and a preparation method thereof. Background technique [0002] Negative air ions, also called negative oxygen ions, refer to oxygen ions that gain excess electrons and are negatively charged. It is formed when oxygen molecules in the air combine with free electrons. Natural discharge (lightning) phenomena, photoelectric effect, fountains, waterfalls, etc. can ionize the surrounding air and form negative oxygen ions. Negative oxygen ions enjoy the reputation of "Vitamin Oxygen", "Air Vitamin", "Longevity Supplement" and "Air Vitamin" in the medical field. [0003] Polyester, commonly known in China as "Accurate", has a wide range of uses and is widely used in the manufacture of clothing fabrics and industrial products. Polyester has excellent set properties. The flat, fluffy shape or pleats ...
