Description
Technical Field
The invention relates to a preparation method of a phenol yellowing resistant spandex fiber, and belongs to the technical field of polyurethane fibers.
Background
Spandex is Polyurethane elastic fiber (Polyurethane) for short, has good elastic property and breaking strength, and is widely applied to the field of textiles. One of the main raw materials for preparing spandex is polytetrahydrofuran, which contains antioxidant BHT (2, 6-di-tert-butyl-p-cresol) for preventing the polytetrahydrofuran from being oxidized during storage. However, the antioxidant BHT reacts with nitrogen oxides in the air to generate DTNP (2, 6-di-tert-butyl-p-nitrophenol), the DTNP is colorless in an acidic state, and when the DTNP meets an alkaline substance, the DTNP is immediately yellowed to enable the surface of spandex fibers to be yellowed, and the yellowing is called phenol yellowing.
At present, spandex fabrics on the market are prevented from phenol yellowing by soaking in a phenol yellowing resistant agent. For example, patent CN 101116568B discloses a method for manufacturing a phenol-yellow resistant nylon fastening tape, which comprises the steps of putting the nylon fastening tape into a dip dyeing machine, cleaning, whitening, finishing, dehydrating, fluffing, performing phenol-yellow resistant finishing and gluing, performing acid soaking in the dip dyeing machine, and drying. Although the method has certain effect, the post-treatment process is relatively complex, and the effective substances exist only on the surface of the fiber, so the method has poor timeliness.
Patent CN 109021509A discloses a phenol yellow resistant functional master batch, a preparation method and application thereof, and phenol yellow resistant terylene, wherein the method comprises the steps of mixing 30-70 parts of polyester, 5-15 parts of organic silicon crude rubber and 5-15 parts of organic acid according to a formula amount, and extruding the mixture by an extruder to obtain the phenol yellow resistant functional master batch. And then adding the phenol yellow resistant functional master batch into the terylene according to 2-3% of the mass fraction of the terylene for mechanical mixing, and finally spinning to obtain the phenol yellow resistant terylene. According to the invention, the polyester fiber is enabled to obtain phenol yellowing resistance by a physical mixing method, but the durability is poor, and the organic acid gradually migrates and loses along with the subsequent dyeing and finishing processing of the textile, wearing and washing of finished clothes and other processes, and the phenol yellowing resistance of the polyester fiber is continuously reduced.
