Embodiment 1

[0045] A PLA composite fiber filament, the PLA composite fiber filament has a skin-core structure, including an inner core layer 1 and an outer skin layer 2 wrapped outside it, and the inner core layer 1 is a continuous filament, the making of the filament The material is a degradable material, and the composition of the outer skin layer 2 includes PLA, which accounts for 80.0%-99.9% of the weight of the outer skin layer 2, and PLA refers to polylactic acid.

[0046] A manufacturing process of the above-mentioned PLA composite fiber filament, the manufacturing process includes the following steps: first drying the filamentous body to remove water, and then sending the dewatered filamentous body into a mixture for dipping operation to obtain an impregnated body, The mixture is a uniform mixture of plasticizer, anti-hydrolysis agent and molten PLA, and then the impregnated body is sent into a mold for compression molding to obtain a molded body, and then the molded body is cooled...

Embodiment 2

[0049] Basic content is the same as embodiment 1, the difference is:

[0050] The diameter of the filament is 0.05-0.5mm, and the thickness of the outer skin layer 2 is 0.05-0.3mm. Preferably, the ratio of the thickness of the outer skin layer 2 to the diameter of the filament is 0.2:1-1.2:1.

Embodiment 3

[0052] Basic content is the same as embodiment 1, the difference is:

[0053] A filament is a single fiber filament or a fiber bundle formed by a plurality of fiber filaments; the types of fiber filaments in the fiber bundle are the same or different. Preferably, the fiber filament is any one of viscose fiber, cotton fiber, hemp fiber, chitin fiber, alginic acid fiber, chitosan fiber, polyvinyl alcohol fiber, polycaprolactone fiber, and polyglycolic acid ester fiber.

Abstract

The invention relates to a PLA composite fiber filament and a making process and application thereof. The PLA composite fiber filament is of a skin-core structure, and comprises an inner core layer and an outer skin layer wrapping the inner core layer, wherein the inner core layer is a continuous filament body, the filament body is made from a degradable material, the constituent material of the outer skin layer is mainly PLA, the PLA refers to polylactic acid, and air flow passages are formed between the inner core layer and the outer skin layer. The PLA composite fiber filament has the advantages that the PLA composite fiber filament not only is good in flexibility and uneasy to break and degum, but also can be completely biodegradable, which is conductive to protecting the environment.A filter tip made by using the PLA composite fiber filament has small suction resistance, uniform flow of flue gas, a good cooling effect and moderate strength.

Description

technical field [0001] The invention relates to a composite fiber filament, in particular to a PLA composite fiber filament and its production process and application. The PLA composite fiber filament has enhanced flexibility and is not easy to break. Background technique [0002] It has become an indisputable fact that smoking is harmful to health. According to reports, smoking is directly or indirectly related to chronic obstructive pulmonary disease, cardiovascular disease, stroke, gastric ulcer, cataract, and at least 12 kinds of tumors (especially lung cancer). )Associated. According to the smoking control report released by the Ministry of Health of China in 2007, nearly 1 million people die from smoking-related diseases in my country every year, of which 100,000 people die from passive smoking-related diseases, especially respiratory diseases and respiratory tumors. Cigarettes are more closely related. [0003] With the continuous development of tobacco industry tech...
