Abstract

Disclosed are a skincare and antibacterial microcapsule finishing agent, and a preparation method therefor and application thereof. The finishing agent comprises an organosilicon microcapsule; the surface of the organosilicon microcapsule is modified by using an organosilicon quaternary ammonium salt; in the organosilicon microcapsule, an aloe extraction liquid and squalene are used as core materials, and tetraethylorthosilicate wall material. A non-adhesive skincare and antibacterial microcapsule finishing agent is obtained by first preparing the organosilicon microcapsule by means of a sol-gel method, and then using the organosilicon quaternary ammonium salt to modify the prepared microcapsule. When in use, the finishing agent is directly added into a cellulose fiber fabric post-finishing liquid, without adding an adhesive; a finished fabric has lasting skincare and moisturizing effects, and also has lasting antibacterial performance; moreover, the touch feel and style of the fabric are not affected.

Abstract

The present invention provides a method for extracting toosendanin, comprising: first washing and drying melia azedarach bark or melia azedarach seeds, grinding, and performing extraction by using a cellulase and apectinase water solution; extracting filter residues by successively using buffer solutions with pH values of 2.0-3.0, 5.0-7.0, and 8.0-8.5, and performing membrane separation on the filtrate after extraction by using an organic solvent, intercepting the solution, and concentrating in a low temperature to prepare the toosendanin. In the present invention, semi-bionic technology is inventively used to implement separation and extraction to raw materials of the toosendanin, so that the obtained toosendanin solution contains more effective ingredients and can be absorbed by an animal body; then membrane separation and retaining technology is combined to obtain a toosendanin product with a molecular weight less than or equal to 1000 Da. Under the synergistic effect of the semi-bionic technology and the membrane separation technology, the content of the effective ingredients of the finally obtained toosendanin product is higher.

Abstract

A downproof fabric containing composite fibers, and manufacturing method thereof. A greige fabric is formed by weaving warp yarns and weft yarns according to a fabric weave. Cotton yarns are utilized for the warp yarns, and composite contraction fibers are employed for the weft yarns. The composite contraction fibers are fabricated by means of a filament retwisting process employing a polyester contraction fiber (2) and a polyester composite fiber (1). The manufacturing method comprises the following process steps: filament retwisting → warping → sizing → weaving → turning and stitching → enzymatic padding, stacking, and resting → scouring and bleaching → stentering → peeling → washing → softening and setting → finished product. The fabric utilizes a composite contraction fiber and is contracted and bulked by means of a printing and dyeing process, thus achieving downproofness. In addition, the fabric has superior breathability, moisture permeability, and a noise reducing effect.

Abstract

An Eucalyptus oil auxiliary agent, preparation method thereof, and fabric-finishing working solution. The Eucalyptus oil auxiliary agent comprises 5-20 parts of Eucalyptus oil micro-capsules, 5-10 parts of Eucalyptus oil, 1-20 parts of non-ionic emulsifier, 5-10 parts of anionic thickener, 5-10 parts of polyurethane adhesive, and 30-50 parts of deionized water. The preparation method of the auxiliary agent employs an emulsion technique and dissolves the Eucalyptus oil in the emulsifier, thus obtaining the auxiliary agent having superior affinity and absorption properties with respect to fabric fibers. The eucalyptus oil micro-capsules are also added to the auxiliary agent, such that a retention time of effective components of the Eucalyptus oil is lengthened with the protection of capsule walls, thus enabling the auxiliary agent to be effective for a long time, and retaining a superior effect when the fabric is used. In addition, one or more types of essential oils can be added to the emulsifier, thus enhancing oxidation resistance of the essential oils, improving storage stability of the auxiliary agent, and preventing gravity-caused layering after long storage. The preparation method is simple and easy to perform, thus providing practicability.
