[0006] 3.TI: Ultrafine synthetic fibers containing organic and inorganic lightstabilizers with lasting light resistance and manufacture thereof. INVENTOR: Hashimoto, Takashi; Watanabe, Koji; PATENT NUM.: JP 11247025 A2 14 discloses a UV-resistant ultrafine polyester, which uses Metal oxides are used as anti-ultraviolet materials, but the fineness of the obtained fibers is only 0.8dtex, which is not only weak in anti-ultraviolet, but also has poor mechanical properties, which cannot meet the needs of applications in related fields, such as clothing and construction.

Embodiment 1

[0032] Preparation of anti-ultraviolet additive through surface coupling treatment:

[0033] Add 40kg of titanium dioxide and 3kg of coupling agent into 300 liters of ethanol solution. Stirred by a strong stirrer, heated in a water bath, gradually raised to 80°C, and refluxed at a constant temperature for 60 minutes. Dry the processed powder in a blast drying oven with a temperature of 67°C. After drying, it is finely ground in a ball mill.

[0034] Preparation of UV-resistant functional masterbatch:

[0035] The anti-ultraviolet additives and adhesives treated by surface coupling are mixed evenly with bright polyester chips, and then added to a twin-screw blender for masterbatch preparation.

Abstract

The present invention relates to a anti-ultraviolet superfine polyester fibre and its preparation process characterized by that the weight composition is 98-70 parts of polyester and 2-30 parts of surface coupled anti-ultraviolet additive, the titer of the fibre is 0.3-0.7dtex, the grain size of the anti-ultraviolet additive is 20-200nm. In this invention, because the anti-ultraviolet additive is treated with coupling agent to increase the additive amount, the anti-ultraviolet superfine polyester has not only remarkable ultraviolet resistance but also better binding ability with parental material and excellent mechanical property, providing large application field and significant social and economical benefit.

Description

technical field [0001] The invention relates to a functional polyester and a preparation method thereof, in particular to an anti-ultraviolet superfine polyester and a preparation method thereof. Background technique [0002] At present, with the development of light and thin textile products, superfine polyester has become one of the leading products of new synthetic fibers. Compared with conventional polyester, it has many advantages. From the perspective of use, it is the most innovative simulation material. . Of course, ultra-fine polyester also has some disadvantages such as high price and high processing cost, especially in post-processing, which requires more care and skill, serious electrostatic phenomena, and decreased dyeing depth and fastness, all of which need to be improved. However, microfiber has many special and excellent properties, and its market competitiveness is strong, so its development has become a top priority. Its development will not only bring ne...
