Problems solved by technology

At present, the most commonly used anti-ultraviolet fiber is full-dull fiber, which has weak anti-ultraviolet ability. Although some technicians increase the anti-ultraviolet ability by adding too much titanium dioxide content, too much titanium dioxide content will cause hair loss during spinning and weaving. If there are too many filaments and broken filaments, the quality of the fiber fabric is difficult to achieve the excellent performance of wearing comfort, appearance and crispness, so it is abandoned.
In addition, because most of the full-dull fibers at home and abroad are polyester fibers, their molecular structure is relatively compact, and they need to be dyed under high temperature and high pressure, which has the disadvantages of high energy consumption and difficulty in continuous industrial production. Problems such as fiber dyeing in the same bath

Abstract

The invention discloses an ultra-extinction memory fiber and a preparation method. The ultra-extinction memory fiber is prepared by a method for differentially distributing titanium dioxide content in a skin-core composite structure. The problems that the conventional complete-extinction fiber has poor ultraviolet resistance, breakage in the weaving process is relatively serious, and clothes produced have a low sagging degree are solved. The ultra-extinction memory fiber adopts the skin-core structure, and has the average titanium dioxide content of more than 3% and high ultraviolet resistance; fabric woven by the ultra-extinction memory fiber is bright in color, comfortable, sagging, stiff and smooth and high in resilience, and has much higher dyeing property and ultraviolet resistance than the conventional polyester and other complete-extinction fibers.

Description

technical field [0001] The invention relates to a super-extinction memory fiber and a preparation method thereof, belonging to the technical field of textiles. Background technique [0002] At present, anti-ultraviolet fiber is the clothing fiber used to resist ultraviolet rays in the world, and it is the preferred textile fiber to reduce the incidence of skin cancer. At present, the most commonly used anti-ultraviolet fiber is full-dull fiber, which has weak anti-ultraviolet ability. Although some technicians increase the anti-ultraviolet ability by adding too much titanium dioxide content, too much titanium dioxide content will cause hair loss during spinning and weaving. There are too many threads and broken threads, and the quality of its fiber fabric is difficult to achieve the excellent performance of comfortable wearing, beautiful appearance and crispness, so it is abandoned. In addition, because most of the full-dull fibers at home and abroad are polyester fibers, t...
