Title:
PROCESS FOR PREPARATION OF HIGHLY UV-RESISTANT FUNCTIONAL FIBRE, FUNCTIONAL FIBRE AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/112734
Kind Code:
A1
Abstract:
The present invention provides a process for preparation of a highly UV-resistant functional fibre, the functional fibre, and use thereof. The process comprises: mixing titanium dioxide and a resin powder for blending granulation to obtain a UV-absorbing master batch; drying same and then mixing with resin slices, and melt-spinning the mixture to obtain the highly UV-resistant fibre. In the blending granulation, the extruding temperature is set to be 160 to 350ºC, and the rotational speed of a screw is 150 to 2500 rpm. The fibre and fabric prepared by the present invention have excellent mechanical properties, which can reach the standard of ordinary fibres, and at the same time have a strong UV resistance. A DTY fibre has a strength of 4 cN/dtex, and an elongation at break of 21%, completely satisfying requirements of various weaving.
