Problems solved by technology

Although the sea-island fiber also has high anti-permeability, the number of island components in the ordinary sea-island fiber is small. If an excellent anti-permeability effect is to be achieved, the content of the island components will inevitably be increased, resulting in a larger area of ​​a single island, thereby There is a risk of abnormal fiber cross section and poor spinnability

Abstract

The invention discloses highly anti-transparent sea-island composite fiber. The content of inorganic particles in an island component is 8 wt% or above, and the content of inorganic particles in a sea component is 5.0 wt% or below; the island component accounts for 10 wt% or above of the whole fiber; and the number of islands on the cross section of the single fiber is 30 or above. The obtained fiber and fabric have good spinning and weaving processability, and also have excellent anti-transparent, anti-ultraviolet and heat-shielding properties.

Description

technical field [0001] The invention relates to a sea-island composite fiber with high permeability resistance and a fabric obtained by using the fiber. Specifically, it relates to a composite fiber with a sea-island cross-section structure and different inorganic particle contents in the sea-island two-component polymer. Background technique [0002] Visual shading is an important performance of textiles. In the field of clothing, it is related to the most basic function of covering the body; in the field of decoration and military, it involves special visual requirements such as one-way perspective and camouflage. In addition, with the worldwide use of Freon in large quantities and the increasing environmental pollution, the ozone layer in the atmosphere has been severely damaged. Long-term exposure to ultraviolet radiation will reduce the lifespan of organic molecules and reduce the immune function of the human body. It will not only damage the skin and cause dermatitis,...
