Description
Technical Field
The invention relates to a textile, in particular to a modified household textile.
Background
In recent years, natural plant extracts are paid more attention by people due to good environmental compatibility, degradability, nontoxicity, health care and other properties under the global concept of green, ecological and environmental protection.
Artemisia argyi H.L.v. & Vaniot, also known as Xiaomao, Bingtai, Thymus, Artemisia, Polygonum, mugwort, moxa, moxibustion, medicinals, yellow grass, moxa, etc. Perennial herbs or semi-shrubs are formed, and plants have strong fragrance. Stem simple or few, brown or sallowly brown, slightly lignified at the base, with few short branches at the upper part, thick paper of leaves, grayish white short, soft hair at the upper part, usually without or with very small pseudoleaves at the base; the upper leaves and bracts have half-feathered and half-split shape, head-shaped inflorescence is elliptical, the corolla is tubular or high-foot cup-shaped, the exterior has glandular spots, the flower is narrow-line-shaped, and the style is nearly equal to or slightly longer than the corolla. The slim fruit is oblong. Ben Cao gang mu records that "Bai Hao" and "Bai ai", the leaves are kneaded into cotton-like shape; it is warm, bitter, pungent and slightly sweet in nature when used as a medicine.
The wormwood is a common plant and a common traditional Chinese medicine, but contains rich knowledge and connotation in elements of Chinese culture. People not only use the tea to pray for the delightful and safe life, but also use the tea to relieve the pain of themselves, and meanwhile, the tea is warm and fragrant, so that people can enjoy the taste of the tea delicately and finely. The eupatilin is an effective component extracted from natural wormwood, and the active substance of the eupatilin has the functions of antibiosis, mosquito repelling, dehumidification and allergy resistance, and has broad-spectrum health care function. The effective component eupatilin of the wormwood is endowed to the textile, so that a product with antibacterial and mosquito-repellent functions can be obtained, and is favored by consumers.
At present, the home textile product has the additional functionality of an industrial trend, and the home textile product with the functions of antibiosis and mosquito repelling gradually appears in the home textile market, but the functional home textile product derived from natural plants is less, the effect is poor, the durability is poor, and the primary color of the fiber influences the later-stage dyeing and printing, so that the dyeing and printing is not pure in color and poor in brightness.
