Comparing the disposable soft tissue prepared in examples 1 to 5 with the existing disposable soft tissue, the disposable soft tissue prepared in examples 1 to 5 has better mechanical properties, which are shown in that no fracture occurs after the soft tissue is used for wiping and adsorbing liquid, and the existing disposable soft tissue (the area of the disposable soft tissue is the same as that of the examples) is used for wiping and adsorbing the same amount of liquid and fracture occurs in the middle of wiping and adsorbing, so that the disposable soft tissue is higher in mechanical strength, less prone to fracture after immersion, better in liquid absorption effect per unit area and higher in water absorption performance compared with the existing disposable soft tissue.
Wherein the disposable soft cotton towel adopts a twin-woven non-woven fabric technology; the Zi-spun non-woven fabric has the advantages of simple raw material, advanced process, no discharge in the production process, production cost greatly lower than that of the traditional glued dust-free paper spunlace non-woven fabric and wood pulp spunlace fabric, and technical and product advantages of the Zi-spun non-woven fabric also comprise
1. The product has wider application field, not only can replace spunlace non-woven fabrics and dust-free paper bases widely applied to the market of disposable wet tissues, but also can be used in other industrial application fields with wide prospects, such as liquid absorption, industrial filtration, sound and heat insulation and the like, such as an absorption core body of a disposable sanitary product.
2. The production process is energy-saving and emission-free; the product is mainly made of natural wood pulp and consolidated by superfine fibers, the discarded objects after being used are easy to degrade, the project accords with the industry development direction encouraged by the government, and the related policy guidance is extremely favorable.
3. The melt-blown microfiber, one of the main components, is one order of magnitude smaller than other natural fiber or synthetic fiber in diameter, so that the fiber has large specific surface area, soft material, skin friendliness, good water absorption capacity and strong cleaning and decontaminating capacity.
The cotton soft towel has wide application, and can be used for daily household use, medical application, cosmetics and the like; according to different purposes, the application is selected as a base material, and other materials are added to prepare products with different purposes;
for example, corresponding antiviral wood juice can be added into the disposable cotton soft towel, wherein the antiviral wood juice is formed by mixing alcohol, deionized water, Chinese juniper hydrolat, vitamins and surfactants, and the volume ratio of the alcohol, the deionized water, the Chinese juniper hydrolat, the vitamins and the surfactants is 3-5: 20-30: 4-6: 1-3: 1. by matching with excellent water absorption performance and mechanical property of the liquid immersion device, the liquid immersion device can not drop liquid after immersion, and avoids the fracture; the antiviral wood juice contains alcohol with bactericidal effect, and the Chinese juniper wood hydrolat has antibacterial, antifungal and acarid-expelling effects, and during application, vitamins can be retained on skin surface, and after skin absorption, the skin can be improved, and the facial cleaning effect can be improved.
Corresponding antiseptic solutions may also be added to disposable cotton swabs to form disinfectant wet wipes that may be used to disinfect and/or decontaminate any surface (e.g., food service tables, medical instruments, surfaces in constant contact, bathroom benches, toilets, laboratory tables, bed-side panels, telephones, door handles, etc.). The stability of the germicidal solution and the wettability of the wet wipe may be enhanced by selectively controlling the components used in the germicidal solution and their relative amounts, as well as controlling the properties of the wet wipe itself. In this manner, stability and wettability are maximized, and the disinfectant wet wipe can effectively combat (e.g., reduce or completely destroy by a measurable amount) a broad spectrum of pathogens upon exposure. Examples of pathogens that can be inhibited include bacteria (including cyanobacteria, mycobacteria, and bacterial spores), lichens, small fungi, protozoa, prions (virinos), viroids, viruses, fungi (such as molds and yeasts), and some algae.
Still disposable cotton soft piece of cloth is used in the diaper in the past, and wherein the disposable cotton soft piece of cloth of this application has outstanding hydroscopicity, can avoid the diaper to appear the edge leakage, and preferential mechanical nature can guarantee that the diaper is walked the in-process at the baby moreover, the condition that can not appear splitting.
