Problems solved by technology

[0002] Most of the durable fragrance fabrics prepared at present are prepared by preparing spices into microcapsules and sealing them in the structure of the warp and weft yarns of the fabrics, or directly applying the spices on the surface of the fabrics. It is some small molecules, and the infiltration of small molecules will inevitably increase the distance between macromolecules and reduce the interaction force between macromolecules, thereby reducing the tensile strength

preparation example Construction

[0030] The second aspect of the present invention provides a method for preparing a durable floral fabric, comprising the following specific steps:

[0031] (1) Preparation of pre-modified plant fiber: After the plant fiber is pretreated by flash explosion, an organometallic compound is used as a catalyst to graft polylactic acid molecular chains on the hydroxyl group on the surface of the plant fiber to obtain a pre-modified plant fiber;

[0032] a. Flash explosion treatment: the plant fiber is placed in a flash explosion device and flashed under pressure;

[0033] b. Grafting polylactic acid molecular chains: The plant fibers after flash explosion use organometallic compounds as catalysts to graft polylactic acid molecular chains on the hydroxyl groups on the surface of plant fibers;

[0034] (2) Preparation of modified plant fibers: using acetic anhydride solution to graft acetyl groups to the pre-modified plant fibers obtained in step (1) to obtain modified plant fibers; ...

Abstract

The invention discloses fabric with lasting flower fragrance and a preparation method thereof. The fabric with lasting flower fragrance comprises modified plant fibers and perfume. The compact structure of plant fiber bundles is destroyed by flash explosion treatment, so that lignin and hemicellulose are lost along with treatment, the hardness of the plant fibers is reduced, the specific surface area of the plant fibers is increased, the accessibility and hydrophobicity of the plant fibers are improved, thus polylactic acid molecular chains are tightly attached to the surface of the fabric, the density of the fabric is increased, the perfume is sealed in the fabric, and the loss of the perfume during washing is reduced; bond energy of polylactic acid molecules is improved by acetylation of the plant fibers, so that bonding points between polylactic acid molecular chains are increased, intermolecular hydrogen bonds are generated with adjacent hydroxyl groups while intramolecular hydrogen bonds are formed, thus complex interface bonding grids are formed on the surfaces of the plant fibers, and the wear resistance of the plant fibers is further improved while the tensile strength of the fabric is guaranteed.

Description

technical field [0001] The invention relates to the technical field of floral fragrance fabrics, in particular to a durable floral fragrance fabric and a preparation method thereof. Background technique [0002] Most of the durable fragrance fabrics prepared at present are prepared by preparing spices into microcapsules and sealing them in the structure of the warp and weft yarns of the fabrics, or directly applying the spices on the surface of the fabrics. It is some small molecules, and the infiltration of small molecules will inevitably increase the distance between macromolecules and reduce the interaction force between macromolecules, thereby reducing the tensile strength. Therefore, it is very necessary to design a durable floral fabric with strong mechanical properties and a persistent fragrance. Contents of the invention [0003] The object of the present invention is to provide a durable floral fragrance fabric to solve the problems raised in the above-mentioned ...
