Problems solved by technology

However, due to the strong fishy smell of sea mud, low permeability coefficient and low absorption capacity, its active ingredients are difficult to be fully absorbed by the skin, and the use effect is poor.
Moreover, sea mud is rich in colloids, and there are a large number of inorganic ions between the layers, showing hydrophilic and oleophobic properties, which limits its application in many fields such as chemical fibers.
After searching, so far, no precedents have been found at home and abroad to implant sea mud into nylon 6 slices and melt-spin into multifunctional polyamide fibers, and there are no literature reports

Abstract

The invention provides a polyamide fiber containing sea mud and a preparation method thereof. The fiber comprises, by weight percentage, 75-93% of polyamide-6 chips, 3-15% of sea mud powder, 2-4% of chestnut flower extract, 1.6-3% of caryopteris tangutica maxim extract, 0.3-1.7% of Chinese flowering quince fruit seed extract and 0.1-1.3% of coupling agent. The raw materials are processed through multiple ways and blended and molten, the melt is pumped through a metering pump to a spinning assembly to be spun, and the multifunctional polyamide fiber containing the sea mud is obtained according to a conventional postprocessing process. The polyamide fiber is strong in fragrance and good in skin friendliness, has functions of antibiosis, deodorization, ultraviolet prevention, mite prevention, mosquito repellence, skin protection and health care, is good in effect and lasting in effect, has good spinnability, hygroscopicity, breathability, dyeing uniformity and mechanical property, and is excellent in wearability and wide in application scope. Sea mud resources are fully utilized, and the polyamide fiber containing sea mud has predictable huge economic and social benefits.

Description

technical field [0001] The invention relates to a multifunctional polyamide fiber containing sea mud and a preparation method thereof, belonging to the technical field of functional chemical fibers. Background technique [0002] Polyamide fibers are made of amide groups (-CONH - ) is a synthetic fiber made of linear polyamide that is connected with a hydrocarbon group as a structural unit. The trade name is nylon, referred to as PA, commonly known as nylon. It is one of the main varieties of synthetic fibers. Many hydrogen bond structures can be formed between macromolecules, so that it has high crystallinity, and has outstanding advantages in mechanical properties, chemical properties, thermal properties, etc. It can be used alone or blended and interwoven with other fibers. At present, the main varieties of polyamide fiber are nylon 66 and nylon 6, and nylon 6 is the largest yield of polyamide fiber varieties, because of its high breaking strength, small specific gravity,...
