Description

Technical Field

[0001] This application relates to the field of chemical product technology, specifically to a composition and finishing agent. Background Technology

[0002] As the application of hyaluronic acid in skincare continues to expand, its moisturizing and skincare effects are increasingly recognized by consumers. Some functional textile products also incorporate hyaluronic acid to provide these benefits. Currently, there are two main ways to add hyaluronic acid to fabrics: one is during fiber spinning; the other is during fabric finishing. Fiber spinning typically involves harsh conditions. For example, in wet spinning, the spinning solution and coagulation bath are often strong acids, strong alkalis, or organic solvents. During spinning, hyaluronic acid is easily degraded under the influence of acids, alkalis, or organic solvents. In melt spinning, the process is generally at high temperatures, where hyaluronic acid easily decomposes and tends to stick, clogging the spinneret and affecting spinning. Therefore, the most widely used methods in the industry are currently impregnation and padding.

[0003] Hyaluronic acid has a wide molecular weight distribution, ranging from millions of Daltons to hundreds of Daltons. Different molecular weights of hyaluronic acid possess different physicochemical properties and effects. High molecular weight hyaluronic acid has moisturizing and lubricating skincare effects; medium and low molecular weight hyaluronic acid can hydrate and soften the stratum corneum, promote skin nutrition and metabolism, and soften the skin. Organic combinations of different molecular weights can achieve both moisturizing and lubricating effects, as well as skin softening. As the molecular weight increases, the viscosity of hyaluronic acid increases significantly, enhancing its binding ability to fibers, but decreasing its diffusion ability, limiting its presence to the surface of fibers or fabric gaps. Low molecular weight hyaluronic acid, on the other hand, has strong diffusion ability, penetrating deep into the fibers or fabric gaps, increasing the hyaluronic acid content loaded within the fibers. Summary of the Invention

[0004] Therefore, in order to increase the hyaluronic acid content in textiles and solve the problems of low binding rate of single molecular weight hyaluronic acid with fabric fibers and limited skin care function, this application improves the binding rate of hyaluronic acid in fabric fibers and reduces costs by rationally compounding hyaluronic acid of different molecular weights. At the same time, it can effectively improve the skin care effect of hyaluronic acid textile products.

[0005] To address the above problems, this application adopts the following technical solution:

[0029] Inventive effect

[0030] 1. The hyaluronic acid composition provided in this application is composed of a variety of hyaluronic acids with different molecular weights. Compared with the skin care effect of single molecular weight hyaluronic acid, the organic combination of multiple molecular weight hyaluronic acid can achieve the effect of moisturizing and nourishing the skin from the epidermis to the dermis. When used as a textile finishing agent, the textiles treated with it have a better moisturizing effect when worn.

[0031] 2. The hyaluronic acid composition provided in this application has a stronger binding ability with fabric fibers, and the different molecular weights bind to the fabric in different ways. The combination of multiple molecular weight hyaluronic acid can greatly improve the binding rate of hyaluronic acid with fabric fibers. On the one hand, it can improve the moisturizing and skin care effect, and on the other hand, it can effectively prolong the release time of hyaluronic acid to achieve long-lasting moisturizing. Moreover, even after washing, the hyaluronic acid content of fabric fibers treated with the hyaluronic acid composition of this application does not decrease significantly, and it has a more stable and continuous moisturizing effect. Detailed Implementation

[0032] The following description provides exemplary embodiments of this application, including various details to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0039] In a preferred embodiment, the percentage by weight of the hyaluronic acid composition, wherein,

[0040] The first hyaluronic acid or its salt is 0%-20%, for example, it can be 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, or it may not contain the first hyaluronic acid or its salt. Preferably, the first hyaluronic acid or its salt is 10-20%.

[0049] This application also provides a finishing agent comprising any of the hyaluronic acid compositions described above.

[0050] The term "finishing agent" conforms to the general definition in this art, typically referring to textile or fabric finishing agents. These agents are applied to textiles to alter their surface properties, thereby endowing them with special functions. For example, water-repellent and oil-repellent finishing uses a finishing agent with low surface tension to treat fabrics, altering the surface characteristics of the fibers and making the textile or fabric surface less susceptible to wetting and spreading by water or oil, thus achieving the purpose of water and oil repellency. Stain-resistant finishing and easy-to-clean finishing are processing techniques that alter the surface properties or state of fibers, making the fabric less prone to dirt adhesion under wearing and use conditions, or making already adhered dirt easier to wash and prevent further staining. In this application, applying the provided finishing agent to textiles or fabrics can increase the hyaluronic acid content in the textiles, thereby improving their moisturizing properties.

[0051] Furthermore, the finishing agent of this application contains high-, low-, ultra-low-, and micro-molecular-weight hyaluronic acid. Different molecular weight hyaluronic acid exerts different effects upon migration to the skin surface. High-molecular-weight hyaluronic acid can form a mesh-like hydration film on the skin surface, preventing moisture evaporation and prolonging the moisturizing effect; low-molecular-weight hyaluronic acid can hydrate and soften the stratum corneum, nourishing the epidermis; micro-molecular-weight hyaluronic acid can be quickly absorbed by the skin, providing deep nourishment. In addition, different molecular weight hyaluronic acid has different binding abilities to fibers. High-molecular-weight hyaluronic acid has a strong binding ability and can form an entangled structure with fibers; low-molecular-weight hyaluronic acid has a strong diffusion ability and can penetrate deep into the interfiber spaces. Therefore, this application, through a rational combination of high-, low-, and micro-molecular-weight hyaluronic acid, provides a finishing agent that, when applied to textiles, not only provides comprehensive three-dimensional moisturizing to the skin but also increases the binding rate of hyaluronic acid in the fabric, achieving long-lasting moisturizing and skin care.

[0053] Further preferably, the composition, by weight percentage in the finishing agent, is 0.1-10%, for example, 0.1%, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, or 10%; the nonionic surfactant is 3-10%, for example, 3%, 4%, 5%, 6%, 7%, 8%, 9%, or 10%; the undecylenoic acid monoglyceride is 3-5%, for example, 3%, 3.5%, 4%, 4.5%, or 5%; and the fatty alcohol polyoxyethylene ether is 3-5%, for example, 3%, 3.5%, 4%, 4.5%, or 5%.

[0054] The nonionic surfactant can be any one or more combinations used in the art. In a preferred embodiment, the surfactant used in this application comprises 3-5% undecenoic acid monoglyceride and 3-5% fatty alcohol polyoxyethylene ether, by weight percentage in the finishing agent.

[0055] This application further provides a method for preparing any of the hyaluronic acid compositions provided in this application as described above, specifically comprising the steps of pulverizing and sieving any three or four of the following: first hyaluronic acid or its salt, second hyaluronic acid or its salt, third hyaluronic acid or its salt, and fourth hyaluronic acid or its salt, and then mixing them evenly.

[0056] The pulverization process can be any method commonly used in the art, such as airflow pulverization.

[0057] The sieving process can use molecular sieves commonly used in the art. There is no limitation on the pore size of the sieve. In a preferred embodiment, the pore size is 60 mesh.

[0058] The sieve apertures used in the sieving processes for any three or four of the aforementioned first hyaluronic acid or its salt, second hyaluronic acid or its salt, third hyaluronic acid or its salt, and fourth hyaluronic acid or its salt can be the same or different. In a preferred embodiment, the sieve apertures are all the same. This ensures that the powder of each hyaluronic acid or its salt is fully and evenly mixed, thereby ensuring that the resulting hyaluronic acid composition for textiles achieves the best performance after finishing.

[0060] Water is added to the mixture while stirring and heating to accelerate dissolution. Stirring continues until a homogeneous solution is obtained. The stirring can be manual or mechanical. Homogenization refers to a process that micronizes and homogenizes the dispersions in the suspension or emulsion system. After a certain period, the finishing agent is obtained.

[0099] The hyaluronic acid content of each knitted cotton fabric obtained in Example 26 was determined according to "CN109298112A A Method for Determining Hyaluronic Acid Content". Specifically, the fabric treated with the finishing solution was accurately weighed and cut into small pieces. After enzymatic hydrolysis with hyaluronidase for 2 hours, the enzyme was inactivated by boiling for 2 minutes. The solution was transferred to a volumetric flask and diluted to the mark with buffer solution. After filtration through a 0.22 μm filter membrane, 20 μL was injected into a liquid chromatograph, the chromatogram was recorded, and the hyaluronic acid content was calculated using the external standard method.

[0100] The knitted cotton fabrics obtained in Example 26 were washed according to the 4N program of a type A washing machine in GB / T 8629-2017, hung to dry, and then the hyaluronic acid content was tested using the method described above. The results are shown in Table 3.
