Spunlace non-woven material containing natural dry petals and preparation method thereof

Abstract

The invention relates to the technical field of spunlace non-weaving, and discloses a spunlace non-woven material containing natural dry petals and a preparation method thereof. The spunlace non-wovenmaterial comprises dry fiber webs and wet fiber webs which are intertwined, and the intact natural dry petals are placed between the wet fiber webs and the dry fiber webs; the natural dry petals areselected from petals which use carotenoids as main pigments and have colors from yellow to red, and the length-width ratio of the natural dry petals is smaller than 10:1. According to the spunlace non-woven material, the characteristics of dry-laid web and wet-laid web spunlace processes are fully utilized, and the whole petals with natural morphology are uniformly distributed in the spunlace non-woven material, so that the spunlace non-woven material has natural beauty care effects, the aesthetic feeling of cloth covers of personal care materials are enhanced, and the technical problems of petal colour fading, color diffusion, short product storage period and easy falling of petals during the production and use process are effectively solved through reasonable process coordination.

Description

technical field [0001] The invention relates to the technical field of spunlace nonwovens, in particular to a spunlace nonwoven material containing natural dried petals and a preparation method thereof. Background technique [0002] Spunlaced non-woven fabrics are mainly made of viscose, polyester and other textile fibers, which are mechanically carded into a net and sprayed with a high-pressure jet into a cloth. The spunlace method is flexible and reinforced, and the fiber is not damaged during the process, which not only maintains the softness of the product, but also enables the product to obtain a higher breaking strength. Spunlace non-woven fabrics are used in personal care and other hygienic materials including beauty masks field has been widely used. Humans have used facial masks for a long time. It has the functions of whitening, moisturizing, acne removal, anti-wrinkle, anti-radiation, etc. Therefore, it has penetrated deeply into people's daily life as a daily car...

AI Technical Summary

Problems solved by technology

[0007] Although the products produced by this process have strong functions and durability, the original functions are often damaged in the process of fiber processing, which limits the health benefits of the finished products.

At the same time, the functionality of the fiber made by this method is directly proportional to the specific surface area of ​​the fiber itself, that is, the larger the specific surface area, the stronger the functionality of the fiber, but the specific surface area of ​​the fiber is limited by the fiber manufacturing process, and the added raw materials often cannot reflect it. due effect

[0008] 2. After-finishing ordinary spunlace non-woven materials, so that the materials can obtain health care functions: the spunlace cloth can be treated with the post-finishing method, although the spunlace cloth can be endowed with health care effects, but due to the use of chemicals in the after-finishing, Not only will it affect the softness of the spunlace fabric, but it will also affect the safety of the product, and will generate sewage discharge during the production process, which does not conform to the concept of green and sustainable development

[0010] 1. It is impossible to evenly and completely disperse large pieces of natural petals into the non-woven material: in order to disperse the petals evenly in the suspension, the above-mentioned plan cuts up the natural flowers and plants, destroying the appearance structure of the flowers and plants, and making the active ingredients drain

[0011] 2. Failure to solve the fading and color diffusion problems of natural petals during the production process: according to the claims and the description, the preferred solution is to use rose petals, etc., but found through the research of the team of the present invention, and Not all petals are suitable for actual production, especially rose petals, roses and other natural petals contain anthocyanins and flavonoid pigments. Easy to dissolve and lose, especially in the case of high water temperature, the loss of pigment is more serious, which will dye the non-woven fabric, thus affecting the aesthetics of the non-woven fabric

In addition, the patent uses fresh petals, which are not only easier to fade, but also the petals are easy to wither after being compounded in non-woven fabrics, and it is not easy to store, resulting in a shorter shelf life of the product

[0012] 3. According to the description of its technical solution and the display of the accompanying drawings, it evenly disperses the sheet-shaped natural flowers and plants on the layer of the wet-laid fiber web. If the combination is not tight, natural flowers and plants will easily fall off during material production and subsequent product processing, which is not conducive to processing and use, but also affects the effective use of health care functions

In view of the above problems existing in the prior art, and according to the market demand in the field of personal care, it is necessary to develop a new type of non-woven material containing whole petals, so that it has good health care effect and does not produce Environmental pollution, and at the same time, it is necessary to solve the technical problems of petal fading, color diffusion, and petals are easy to fall off during production and use
