Abstract

The invention provides a plant-derived nylon master batch. The plant-derived nylon master batch is mainly prepared by blending and melting nylon master batch and modified sarcandra glabra extract; themass ratio of the nylon master batch to the modified sarcandra glabra extract is 84:16. The invention further provides a preparation method of the cellulose fiber. The plant-derived nylon master batch prepared by the preparation method is regular in shape and free of continuous particles, no debris is generated, the particle size uniformity is 95.9-97.2%, and the water content is 0.081-0.089%; for the prepared fiber, the fiber breaking strength is 7.4-8.1 cN / dtex, the elongation at break is 36.2-37.4%, the fiber moisture absorption rate is 11.8-12.2%, and the moisture absorption performance is durable after multiple times of washing.

Description

technical field [0001] The invention relates to a plant source nylon masterbatch and a preparation method thereof, belonging to the field of fiber masterbatch preparation. Background technique [0002] Nylon masterbatch refers to the basic pellets for making nylon fiber, which is an important variety of synthetic fibers. Polyamide is commonly known as nylon (Nylon), and its English name is Polyamide (referred to as PA). It is a general term for thermoplastic resins containing repeated amide groups—[NHCO]—on the main chain of the molecule. It has many varieties and large output. It is a material with a wide range of applications. . However, due to the poor hygroscopicity of the polyamides used to make nylon, its application in the field of moisture-absorbing and moisture-permeable materials such as sportswear is limited. [0003] Plants in nature, such as wormwood, Folium Folium, mint, grass coral, etc., are widely welcomed by technical enthusiasts in the fiber field due to...
