Description

Loofah sponge for flatulence, preparation and application thereof and pillow
Technical Field
The invention relates to the field of bedding, in particular to loofah sponge flatulence sponge, and preparation and application thereof, and a pillow.
Background
The sleep is the guarantee of human energy and physical recovery, and the mattress and the pillow are the supporting platform of human sleep, directly relate to human sleep quality.
At present, the common pillows in the market mostly take memory foam, latex, vacuum foam, buckwheat husk, tea leaves, lavender, cassia seeds and the like as pillow core (filling) materials, wherein the memory foam and the latex pillow occupy larger market share. However, these pillow materials have poor air permeability and moisture diffusion, sweat and water vapor generated during the sleeping process of human body cannot be discharged timely, so that the human body is stuffy, the sleeping quality is affected, and after long-term use, the pillow is bred with mites and other fungi, and the damage is caused to the human body surface, neck, scalp and the like. Meanwhile, the traditional memory foam has the phenomena of easy tearing, easy yellowing and the like, so that the service life of the memory foam material is greatly reduced.
The loofah sponge is a porous biomass material with a three-dimensional net-shaped structure, the porosity of the loofah sponge is as high as 92%, and the gas flux of the loofah sponge is as high as 63546L/m2S, called "memory foam" in plant fibers, has better energy absorption capacity. Related research shows that the loofah sponge can absorb more than 3 times of water by weight of the loofah sponge, andthe moisture-dispersing rate in the 16 th hour is as high as 98 percent. Therefore, the loofah sponge is a natural plant fiber material with high moisture absorption, high moisture dissipation, high air permeability and good energy absorption performance. Meanwhile, modern medical research shows that the loofah sponge contains components such as ribosome inactivating protein, loofah saponin, squalene, isopropyl palmitate and the like; wherein, the luffa ribosome inactivating protein has the function of inhibiting the reproduction of viruses and bacteria; the saponin has antibacterial, antipyretic and sedative biological activities; the squalene has effects of caring skin, improving sleep, and inhibiting growth of mold; isopropyl palmitate is a common emollient in skin care products and can make skin soft and smooth.
Therefore, if the loofah sponge material prepared by mixing and foaming the loofah sponge and the polyether polyol is used as the pillow filling material, the sponge filling material can be endowed with high-efficiency moisture absorption, moisture dissipation and ventilation effects, so that the problems of poor ventilation and moisture dissipation of the existing material are solved, and the antibacterial sleep effect of the filling material is enhanced to a certain extent.
As for the problems of easy tearing and easy yellowing of the existing material, researches find that the natural plant fiber has corresponding effects by modifying the natural plant fiber. Common modification treatment modes comprise alkali treatment, acid treatment and the like, and the loofah serving as a natural plant fiber can be optimized in performance.
Therefore, the sponge material and the corresponding sponge pillow which have the effects of resisting bacteria, helping sleep, having good hygroscopicity and moisture dispersion and simultaneously having the tearing resistance and/or yellowing resistance can be developed by utilizing natural or modified loofah sponge.

Wherein the natural loofah sponge fiber which is not subjected to chemical modification treatment contains 1-behenyl alcohol, cedryl acetate and octadecanol. Relevant research shows that the 1-behenyl alcohol is one kind of effective antiseptic film agent and has inhibition effect on several kinds of virulence factors of gram-positive bacteria. Cedryl acetate has a strong woody flavor and is commonly used as a raw material for daily chemicals. And the octadecanol has lower density and better hydrophobicity, and can promote the microphase separation of polyurethane and improve the shape memory performance of polyurethane foam as an auxiliary agent.
Through NaOH-H2O2The interior of the treated loofah sponge fiber becomes hollow, and a large number of grooves, pores and cracks appear on the surface of the fiber, so that the loofah sponge fiber is more beneficial to absorbing and dissipating moisture, the dryness of the modified loofah sponge pillow surface is ensured, and the loofah sponge pillow can be endowed with excellent moisture absorption and moisture dispersion and air permeability.

The squalene is a substance with light fragrance and high antioxidant activity, and has a certain antibacterial function. Therefore, the flexibility of the modified loofah sponge fiber after alkali-acetic acid mixing treatment is improved, and the extraction of active substances, namely squalene, is facilitated.
By NaOH-CO (NH)2)2Treated loofah sponge fiber, celluloseThe crystal form size is reduced by 36.4 percent, the influence of the crystal structure on the activity of long-chain molecular chain segments is smaller, and the fatigue resistance of the fiber is higher, which shows that the method NaOH-CO (NH) is adopted2)2The treated loofah sponge fiber has a compact crystal structure, and good mechanical properties and fatigue resistance. Furthermore, by the method NaOH-CO (NH)2)22-ethylhexyl trans-4-methoxycinnamic acid, 2-ethylhexyl salicylate, Homosalate and other active substances are detected in the active substances of the treated loofah sponge fiber, and the active substances are ultraviolet filtering agents and are used in sunscreen cream formulas and other personal care products in the global range; this indicates that NaOH-CO (NH) was processed through the process2)2When the treated loofah sponge fiber is applied to preparation of the flatulence sponge, the problem that the flatulence sponge is easy to yellow can be effectively solved.
