An alginate-based fiber is made of a composition comprising an alginate, a cellulose and a polyol plasticizer, such as glycerol. The fiber is produced through extrusion in a curing bath containing calcium. The fiber provides excellent strength and flexibility in its unhydrated state for textile applications. The fiber can be used to produce textiles as compostable alternatives to petrochemical based polymers.

The present invention discloses an algae modified pp spunbond non-woven fabric, which contains 0.1-2% of alginate. The algae modified pp spunbond non-woven fabric has a moisture regain of 0.2-3.5%, and an antibacterial rate ≥98%. The algae modified pp spunbond non-woven fabric prepared in the invention contains modified alginic acid, and also has hydrophilic functional groups, such as hydroxyl and amido groups, and hydrophobic functional groups such as branched alkyl groups. After spinning with pp into non-woven fabrics, protons can be both generated and received, so that when liquid is encountered on the surface of non-woven fabrics, the surface tension of liquid can be significantly reduced; additionally, there are a large number of gaps in the dense interpenetrating network structure formed by the modified alginic acid, which forms a structure like sponge having good hygroscopicity; moreover, the algae modified pp spunbond non-woven fabric absorbs water rapidly, the surface remains dry after absorbing water, and it can absorb many times its mass of water, so it has an excellent hydrophilicity.

Methods of culturing and manufacturing of cells on a large-scale level are disclosed. Particularly, a manufacturing system and device, and methods of using the system and device for culturing and manufacturing cells in hollow fibers made from alginate polymers are provided.

The present invention relates to an air conditioning device. The air conditioning device sucks air through a suction portion and sending the sucked air to a blowing portion to perform air conditioning, wherein the suction portion includes a virus killing portion formed of a fiber to which copper ions are bonded and killing a virus, the virus killing portion includes a caz fabric configured to contain 5 to 50 wt % of an antiviral alginic acid conjugate fiber configured so that the copper ions are contained in an amount of 6,000 to 100,000 ppm in a fiber, and the virus killing portion has a differential pressure exceeding 0 Pa and less than 10 Pa.

Provided is a spinning solution, comprising a cannabidiol powder and an alginate solution. Besides, the present invention further provides an alginate fiber comprising cannabidiol, and the preparation method and the use thereof. The cannabidiol powder in the spinning solution can be evenly dispersed in the alginate solution, so that the spinning solution of the present invention can be applied to wet spinning to form the alginate fiber comprising cannabidiol. The alginate fiber comprising cannabidiol has anti-oxidative, anti-bacterial, antiinflammatory, and anti-allergic abilities.
