Description

Negative ion finishing liquid and its preparation method and negative ion functional seamless underwear

technical field

The invention belongs to the field of finishing of clothing products, and in particular relates to an anion finishing liquid, a preparation method thereof, and anion functional seamless underwear.

Background technique

Along with the raising of material living standard, people pay more and more attention to the health of human body and health care. A large number of textile fibers and textile products with various health functions have emerged. Among them, underwear with health functions has attracted more and more attention, and it has also become one of the research hotspots in the field of clothing products.

The concentration of negative ions in the air is one of the signs to measure the quality of the air. The World Health Organization stipulates that the standard concentration of negative ions in fresh air should not be lower than 1000-1500 per cubic centimeter of air. The concentration of negative ions in the air not only indicates the quality of the air, but also the atmospheric environment with high concentration of negative ions has certain medical care effects on human health. How textiles increase the concentration of negative ions has become one of the main topics in the field of health textiles. Some researchers have developed a new type of fiber with negative ion health care function from textile materials. For example, the Chinese patent with the publication number CN1294208 introduces a kind of negative ion far-infrared synthetic fiber, but the number of negative ion emissions of the fiber is less and it is processed in the post-spinning process. The machine needles are easily damaged, which greatly increases the processing cost and limits the development and utilization of this fiber; the Chinese patent with the publication number CN1827868 provides a kind of negative ion fiber and its preparation method, which adopts the method of adding negative ion catalyst to the fiber material. The oxytocin is made into a new type of fiber, and then applied to the field of clothing, such as underwear, wherein the ionic oxytocin is mainly composed of opal 40-60%; diatomite 15-25%; seaweed charcoal 5-10%; bamboo charcoal 2 -4%; 2-4% of medical stone; 3-6% of shell; 4-10% of titanium dioxide;

There are also researchers starting from the product structure to play the functionality of negative ions. For example, the Chinese utility model patent with the notification number CN200966348 discloses an infrared negative ion health care clothing, which includes a clothing body, which corresponds to the wearer's acupuncture points or joints. An infrared negative ion health care cloth is provided, and the infrared negative ion health care cloth is formed by blending natural fibers and fibers added with infrared nano ceramic powder and negative ion powder. There is no negative ion seamless underwear functional finishing agent and the content of finishing technology in this background technology.

There are also researchers who make fabrics have the functionality of negative ions by post-processing clothing products. For example, the Chinese invention with the publication number CN101139800 provides a treatment technology that can make fabrics produce negative oxygen ions in a stable and sufficient amount. Cationic surfactant treatment, and then wash with water less than 20 ° C, because the cationic surfactant on the fabric cannot be completely washed, so that the cationic surfactant on the fabric remains about 0.3-3.0% relative to the fiber quality, and finally the fabric is used quarterly Ammonium salt is used for surface treatment. The fabric treated by this technology can continuously and stably emit negative oxygen ions, reaching about 4200ML. It can quantitatively and stably emit negative oxygen ions. The function will not decrease with the increase of washing times. Into underwear, pajamas and home textile products, etc. However, this method is cumbersome.

Seamless underwear is a one-time molding underwear produced by novel special equipment, so that the neck, waist, hips and other parts do not need to be seamed. It moved many fashion designers and became the development trend of underwear. Integrating the function of negative ions into seamless underwear products, and having both the functionality of seamless underwear and negative ions has become the goal pursued by researchers.
