Description
Preparation Method of Antibacterial Down Feather
Technical Field
The present invention relates to the technical field of textile materials, and more particularly relates to a preparation method of antibacterial down feather.
Background Art
In recent years, a down feather product is increasingly loved by customers due to its excellent lightweight and warm-keeping characteristics. In the fields of both clothing or home textiles, the market of products such as down coats, down quilts and down pillows is increasingly wider, and the acceptability of the customers is increasingly higher. Down feather commonly seen in the current market originally is duck down and goose down, both belonging to protein fiber and being natural nutrient substances of bacteria and mould, and bacteria are bred very easily. Especially, in order to obtain good down penetration resistance, some fabric adopts a high count and high density manner with the assistance of a special after-finishing technology, breathable performance of the fabric is lowered, bacteria are commonly anaerobic, and thus, in an environment poor in breathability, the bacteria can be bred more easily. Along with constant pursuing of people for environment-friendly and healthy life, more customers start to pay attention to the antibacterial and bacteriostasis performance of products, thus some down feather antibacterial and bacteriostasis technologies also occur in the field of down feather products, and more researchers are committed to research and development of antibacterial and bacteriostasis down feather products.
A method for padding a silver-loaded nanometer antibacterial agent is disclosed in
CN 103882723A; a method for dipping or spraying a chitin solution is disclosed in CN105862434A, and antibacterial performance of natural antibacterial substance chitin is adopted to prepare antibacterial and bacteriostasis down feather fiber. For an existing antibacterial and bacteriostasis down feather technology, an antibacterial agent is finished on the surface of the
2018102132 11 Jul 2018 down feather fiber mostly by adopting a dipping or spraying method, down feather is endowed with certain antibacterial performance within a short period of time due to the method, but because the surface of the down feather fiber has a compact water-repellency structural layer, such a type of antibacterial agent cannot be soaked into the down feather fiber, washability and long-acting performance of the antibacterial down feather are extremely poor, and requirements of the customers cannot be met. A method for finishing chitin and nanometer titanium dioxide on down feather fiber by utilizing an adhesive is disclosed in CN104947209A, the method makes the down feather fiber obtain a long antibacterial and bacteriostasis effect, but after treatment by the adhesive, filling power of the down feather product can be greatly lowered, and a warm keeping degree and a comfort degree of the down feather product are seriously affected.
