Problems solved by technology

[0002] At present, bulky yarn is widely used in the production of carpets. The yarn is made into carpets through the process of cut pile or loop pile tufting. Because bulky yarn has low price, stain resistance, light weight, and resistance to humidity and chemicals With many advantages such as inertness and simple production, it has become the most economical filament for making carpets. During use, carpets are prone to fading and aging under the influence of ultraviolet light, which affects the aesthetics of the carpet. At the same time, it also faces a significant problem. The problem is that carpets are often used in crowded public places or homes. Carpets are prone to cross-infection due to dirt and dirt. The current situation of epidemic prevention and control is still not optimistic, so the antibacterial properties of carpets are particularly important.

Abstract

The invention relates to a bulked yarn and a preparation method thereof. The bulked yarn is prepared from the raw materials of waste plastic materials and color master batches, an antibacterial material and a UV stabilizer are combined, and the BCF bulked yarn is prepared by adopting a one-step production process. The preparation method comprises the steps of drying crystallization, mixing melting, spinning, side blowing cooling, oiling, pre-network, drafting, bulking deformation, cooling, network knotting and winding. The prepared BCF bulked yarn is soft, fluffy, environmentally friendly, recoverable and excellent in light aging resistance and antibacterial performance, the antibacterial inspection is based on a GB / T20944.2-2007 absorption method, the antibacterial performance reaches 99%, the light aging resistance inspection is based on JF03-1301-2010, the visual gray level after the test is larger than or equal to level 4, and the light aging resistance is excellent; and recycled materials are used, waste is converted into raw materials, the purposes of resource regeneration, reducing energy consumption in the production process and saving resources are achieved, and great economic value and social significance are achieved.
