Embodiment 1

[0033] In this embodiment, the process of drug loading and releasing includes: hollow fiber 10, placing hollow fiber staple fiber and drug in a sealed container, the drug can be liquid drug or drug solution, adding a small amount of broken glass to the bottom of the container. After the airtightness inside the container is stable, the air in the container is evacuated to a vacuum state with a vacuum pump. Continue to maintain the vacuum state for about 15min. If the test loading effect is qualitative, the method of intermittent vacuuming can be adopted. After the vacuum was stabilized for 3 minutes, the vacuum pump was stopped, and the air pressure in the container was restored to the standard atmospheric pressure, and then the vacuum operation was performed again. This operation is repeated 2 to 3 times. The purpose of this operation is to make a certain amount of air in the hollow fiber to form an air bag and a steam drum, so as to facilitate the observation of the drug loa...

Embodiment 2

[0035]In this embodiment, the process of attaching and releasing mugwort oil includes: hollow fiber 10, placing the hollow fiber long fiber and mugwort oil in a sealed container, and adding a small amount of broken glass pieces to the bottom of the container. After the airtightness inside the container is stable, the air in the container is evacuated to a vacuum state with a vacuum pump. Continue to maintain the vacuum state for about 15min. If the test loading effect is qualitative, the method of intermittent vacuuming can be adopted. After the vacuuming is stable for 3 minutes, the vacuum pump is stopped, and the air pressure in the container is restored to the standard atmospheric pressure, and then the vacuuming operation is performed again. Repeat this operation 2 to 3 times. The purpose of this operation is to make a certain amount of air in the hollow fiber to form an air bag and a steam drum, so as to facilitate the observation of the loading situation of the hollow f...

Embodiment 3

[0037] In this embodiment, the process of attachment and release of the fragrance oil includes: porous fibers 10, placing the five-hole fiber and the fragrance oil in a sealed container, and adding a small amount of broken glass pieces to the bottom of the container. After the airtightness inside the container is stable, the air in the container is evacuated to a vacuum state with a vacuum pump. Continue to maintain the vacuum state for about 15min. If the test loading effect is qualitative, the method of intermittent vacuuming can be adopted. After the vacuuming is stable for 3 minutes, the vacuum pump is stopped, and the air pressure in the container is restored to the standard atmospheric pressure, and then the vacuuming operation is performed again. Repeat this operation 2 to 3 times. The purpose of this operation is to make a certain amount of air in the five-hole fiber to form an air bag and a steam drum, so as to facilitate the observation of the drug-carrying situatio...

Abstract

The invention relates to a method for attaching and releasing a target substance to a fiber. At least one of fibers, yarns, and textiles with a single-hole or porous structure is used as a carrier, and a liquid target substance is loaded into the target substance by vacuuming. carrier, and then the target substance is slowly released from the carrier. The method for attaching and releasing target substances to fibers of the present invention is simple, can be produced industrially, and can meet the needs of all flexible loading materials. It has a wide range of target substances, safe and stable performance, and is widely used. In addition, the method has repeatable loading and is environmentally friendly. The energy-saving cost is low and the technology is mature, which is suitable for large-scale promotion and use.

Description

technical field [0001] The present invention relates to textile manufacturing technology, and more particularly, to a method for carrying and releasing target substances on fibers. Background technique [0002] With the advancement of technology, it has become a popular trend for textiles to have other functions in addition to wearing functions. For example, the function of attachment and sustained release is an important development direction of textiles in the future. The use of textiles to attach objects is a common application. Currently, the most common encapsulation techniques are mainly coating methods, such as microencapsulated textiles. The target can be first loaded in microcapsules, and then combined with the fabric by coating or cross-linking, and slowly released to the wearer's skin. After the wearer puts on the fabric, the target can be treated anytime and anywhere. convenient. [0003] Then, although the textile attachment system has many advantages, such ...
