[0002] In recent years, with the accelerating pace of life and rising living costs, people are increasingly experiencing sub-health conditions such as sleep deprivation, mental stress, high psychological pressure, and negative moods. Improving sleep quality, alleviating psychological stress, and relaxing tension have become key research and development topics in the sleep environment product market. Textile fillings for sleep environments primarily include fiber meshes such as down, silk, cotton, and chemical fibers. Conventional production of these materials typically lacks fragrance and does not promote sleep. The emergence of essential oils or aromatherapy has provided a new approach to the development of functional textiles.

[0003] Essential oils are metabolic products of some plants, secreted by their protoplasts. They are generally volatile and have a fragrant aroma. Through contact and absorption through the olfactory organs and / or skin, they can, to a certain extent, improve physical and mental health and provide skin care. Among them, Chinese patent application publication number CN105544230A discloses a method for scenting textiles using tea tree oil microcapsules. This method employs microencapsulation technology to encapsulate tea tree oil and adhere it to cotton fabric using a polycarboxylic acid crosslinking agent. This prior art method can slowly release the tea tree oil by varying the temperature, resulting in a scent-releasing fabric with a long-lasting fragrance.

[0004] However, how to attach aromatic microcapsules to textile fillings and keep them there for a long time without affecting the comfort performance of the fillings is a major technical problem at this stage. Summary of the Invention

[0010] The mass ratio of the aromatic waterproof filling layer to the filling base material layer is 5-20:95-80.

[0011] Preferably, the aromatic waterproof short fiber is aromatic waterproof silk, and the non-functional short fiber is ordinary silk; the aromatic textile filler is composed of an aromatic waterproof filling layer, an intermediate layer and a filling base material layer that are composited with each other, and the mass proportion of the aromatic waterproof silk in the aromatic waterproof filling layer, the intermediate layer and the filling base material layer decreases in sequence.

BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following is a clear and complete description of the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] The present invention provides an aromatic textile filler, which is mainly made of aromatic waterproof staple fibers and non-functional staple fibers through a non-woven process; the aromatic waterproof staple fibers contain aromatic microcapsules and have a waterproof function; the aromatic textile filler includes an aromatic waterproof filling layer and a filling substrate layer that are composited with each other, the aromatic waterproof filling layer is close to the user, and the mass proportion of the aromatic waterproof staple fibers is greater than that of the filling substrate layer.

[0023] The aromatic textile filler provided by the present invention has good aromatic odor sustained release, washability and moisture discharge, and can be used to solve the problems of non-aromatic flakes, poor sustained release and poor washability in the prior art.

[0024] See also Figure 1 , Figure 1 Schematic cross-sectional view of the aromatic flocculent sheets in some embodiments of the present invention; wherein 1 is the filling substrate layer, and 2 is the aromatic waterproof filling layer.

[0025] In an embodiment of the present invention, aromatic waterproof staple fibers and non-functional staple fibers are subjected to non-woven processes such as web laying or carding to form a filling substrate layer 1 and an aromatic waterproof filling layer 2, respectively, and compounded to obtain an aromatic textile filler. The aromatic waterproof filling layer 2 is close to the user, wherein the mass proportion of the aromatic waterproof staple fibers is greater than that of the filling substrate layer 1; that is, the filling substrate layer 1 is a fiber mesh mainly formed by non-functional staple fibers, and the aromatic waterproof filling layer 2 is mainly composed of aromatic waterproof staple fibers. The "compound" is generally formed directly by a non-woven process, rather than a direct superposition of two layers; that is, each layer contains aromatic waterproof fibers and conventional fibers, but in different proportions, and the side with a larger proportion of aromatic fibers is closer to the human body.

[0026] In the present invention, the aromatic waterproof staple fiber is a filling fiber material containing aromatic microcapsules and having a waterproof function; its fiber matrix is ​​a staple fiber commonly used in home textiles and clothing fillings, such as down, silk, cotton, viscose, and chemical fiber. Down and silk are protein fibers, while cotton and viscose fibers are cellulose fibers; chemical fiber is the abbreviation of chemical fiber, including but not limited to polyester, nylon, acrylic, etc. Down has a three-dimensional fiber structure and excellent thermal insulation properties; in contrast, cotton, silk, and chemical fibers are generally linear. In addition, the staple fibers are fibers that are shorter than filaments. For example, the length of cotton fibers can be between 33 and 38 mm.

[0027] For example, the aromatic waterproof staple fiber can be aromatic waterproof down, aromatic waterproof silk, or aromatic waterproof cellulose fiber, which are functional staple fibers.

[0028] The aromatic waterproof short fibers can be obtained according to the following process in the embodiment of the present invention: non-functional short fibers are sequentially subjected to aromatic microcapsule finishing and waterproofing treatment.

[0029] The aromatic microcapsule finishing method involves composite treatment of the substrate using an aromatic microcapsule finishing agent. According to the technical solution of this application, the aromatic microcapsule finishing agent can be a mixed liquid of microcapsules (i.e., a finishing liquid); the microcapsule wall material is a macromolecular material, and the core material is preferably a natural plant essential oil, such as commercially available products from Tanner Chemicals and Proneem (France), which have a pure aroma and moderate wall strength. The embodiments of the present invention do not specifically limit the type of aromatic essential oil, for example, lavender and rose scents can be used.

[0030] Microcapsules, also known as microcapsules, are small particles containing an active ingredient or core material surrounded by a coating, or shell. Sometimes, each microcapsule can contain several core materials (either the same component or different components). While there is no universally accepted scale for microcapsule size, their diameter can vary from 1 to 1000 μm. The aroma microcapsules described herein are capsules with a fragrant aroma wrapped in a polymer wall material. When the wall material is squeezed and ruptured, the aromatic essential oil inside is released.

[0031] The finishing liquid used for the aromatic microcapsule finishing described in the embodiments of the present invention comprises the following components by weight: 100 parts water, 1-8 parts aromatic microcapsules, and 0.5-1 part fixing agent. The components can be stirred and mixed to prepare the finishing liquid. Furthermore, a penetrant (such as JFC or Rapid Penetrant T) is preferably added, but a softener is not added, to ensure the effectiveness of subsequent waterproofing. According to the technical solution of this application, the fixing agent is preferably one or more of a hydroxylated acrylic resin or an isocyanate-based waterborne polyurethane.

[0032] In some specific embodiments of the present invention, washed down, silk, or cotton is dehydrated and then immersed in a finishing solution containing aromatic microcapsules to fix the aromatic microcapsules to the fibers. The aromatic waterproof staple fibers contain a fixing agent. Preferably, the bath ratio is 20-60, the immersion time is 20-40 minutes, and the finishing solution temperature is 20-40°C. The impregnated fibers are centrifuged to dehydrate, with a liquid pick-up rate of 30%-80%. After dehydration, they are dried in a dryer at a temperature of 70-120°C to obtain a fiber material containing aromatic microcapsules.

[0033] The bath ratio is the ratio of fabric weight to dye liquor volume during dyeing, i.e., the ratio of fiber / down weight to the volume of the finishing liquor. The pick-up rate indicates the amount of liquid carried by the fabric after squeezing. The calculation formula is: pick-up rate = (fabric weight after squeezing - fabric weight before squeezing) / fabric weight before squeezing * 100%. In this context, this refers to the ratio of the increase in wet fiber weight after soaking and dehydration to the mass of the dry fiber, expressed in %.

[0034] The fiber material containing the aromatic microcapsules described in the embodiments of the present invention is treated with a water-repellent treatment to impart a hydrophobic and water-resistant effect to the fiber. This reduces the loss of the aromatic microcapsules during washing, helping to overcome the problem of filler resistance to washability. For hygroscopic fibers such as silk, cotton, and viscose, the water-repellent treatment can reduce the moisture content and moisture absorption rate of the fibers, thereby increasing their dryness and making them more suitable for use during the rainy season.

[0035] According to the technical solution of the present application, the treatment liquid used in the waterproofing treatment preferably includes the following components in parts by weight: 100 parts by weight of water, 2 to 8 parts by weight of a waterproof finishing agent, and 0 to 3 parts by weight of an adhesive.

[0036] The specific preparation method is as follows: first add the adhesive to water, stir it in a high-speed mixer to make it completely dispersed, then add the waterproof finishing agent and stir it at medium speed. According to the technical solution of this application, the waterproof finishing agent is preferably C6 or fluorine-free waterproofing agent, which does not contain PFOA, PFOS and other harmful substances, such as Daikin's TG products, Tona bio-based fluorine-free waterproof finishing agent. LTR 01: When using a fluorine-free waterproofing agent, no adhesive is required. According to the technical solution of this application, the preferred adhesive is sodium isocyanate or an isocyanate water-based bridging agent, such as Hangzhou Zhuoli Chemical's waterproof crosslinking agent ZL-1069A.

[0037] In a specific embodiment of the present invention, the fiber material treated with aromatic microcapsules can be immersed in a treatment liquid containing a waterproof finishing agent to obtain the aromatic waterproof short fiber. Furthermore, the bath ratio can be 10-40, the immersion time can be 20-40 minutes, and the treatment liquid temperature can be 20-40°C. The impregnated fiber is centrifugally dehydrated, and the liquid carrying rate is preferably 20%-60%. After dehydration, it is dried in a dryer, and the drying temperature can be 80-140°C. In an embodiment of the present invention, the fiber material after waterproofing treatment has a good waterproof effect, the soaking time level is within level 1, or the wicking height reaches 0-15mm.

[0038] After waterproofing, the hygroscopicity will be reduced to a certain extent, which can easily cause the flakes to become damp. In the structure of fiber textiles made of the same material, the inner layer fibers have poor water absorption and the outer layer fibers have good absorption, which will form a capillary effect and an additional pressure difference in the outer layer. Under the action of this pressure difference, liquid water automatically diffuses from the inner layer to the outer layer, which is the fiber differential capillary effect. The aromatic textile filler described in the present invention is mainly composed of aromatic waterproof short fibers and non-functional short fibers, which are composited through a non-woven process to form a unidirectional moisture-conducting structure, that is, the aromatic waterproof short fibers and non-functional short fibers are arranged in a special proportion and position distribution, so that moisture / water is discharged in a direction away from the user, thereby solving the problem of unsatisfactory moisture absorption and moisture conduction of the aromatic filler.

[0039] The unidirectional moisture-conducting structure comprises a filling substrate layer 1 and an aromatic waterproof filling layer 2. The aromatic waterproof filling layer 2 is positioned closer to the user, and the weight of the aromatic waterproof staple fibers is greater than that of the filling substrate layer 1. This means that the portion closer to the user has a higher content of aromatic waterproof staple fibers, while the portion farther from the user has a lower content. This design, characterized by different hygroscopic properties on the front and back sides, creates a unidirectional moisture-conducting system that allows moisture to be discharged in a single direction. The present invention rationally arranges the absorbent filling fiber material and the relatively non-absorbent filling fiber material, thereby increasing the moisture conductivity of the flocculent.

[0040] In some embodiments of the present invention, the aromatic waterproof short fiber is aromatic waterproof down, which is mainly used to form an aromatic waterproof filling layer; the non-functional short fiber is ordinary down, which is mainly used to form a filling substrate layer; the mass ratio of the aromatic waterproof filling layer to the filling substrate layer is 5-20:95-80, and they are mixed before use.

[0041] In some embodiments, the aromatic waterproof staple fiber is aromatic waterproof silk, and the non-functional staple fiber is ordinary silk. The aromatic textile filling material comprises a composite aromatic waterproof filling layer, an intermediate layer, and a filling base layer, which can be referred to as a silk floss mat. The percentage of aromatic waterproof silk in the aromatic waterproof filling layer, intermediate layer, and filling base layer decreases gradually. The silk floss mat has a three-layer structure and can weigh 100-350 gsm.

[0042] In other embodiments, the aromatic waterproof staple fibers are aromatic waterproof cellulose fibers, and the non-functional staple fibers are ordinary cellulose fibers. The aromatic textile filling material comprises a mutually bonded aromatic waterproof filling layer, an intermediate layer, and a filling substrate layer, which can be referred to as a flake. The weight percentage of the aromatic waterproof cellulose fibers in the aromatic waterproof filling layer, intermediate layer, and filling substrate layer decreases gradually. The flake has a three-layer structure, in which low-melting-point polyester fibers can be used for bonding. The flake can have a grammage of 60-450 gsm and a thickness of preferably 5-40 mm.

[0043] The embodiment of the present invention provides a method for producing the aforementioned aromatic textile filler, comprising the following steps:

[0044] The non-functional short fibers are sequentially subjected to aromatic microcapsule finishing and waterproofing treatment to obtain aromatic waterproof short fibers;

[0045] The aromatic waterproof short fibers and non-functional short fibers are laid or combed to form an aromatic waterproof filling layer and a filling base material layer, and then compounded to obtain an aromatic textile filling material.

[0046] In an embodiment of the present invention, the preparation process of the aromatic waterproof staple fiber is as described above; the aromatic microcapsules are fixed thereon, and the soaking time level is within level 1, or the wicking height reaches 0-15 mm.

[0047] After obtaining the aromatic waterproof staple fibers, embodiments of the present invention utilize a non-woven composite method to combine them with non-functional staple fibers to form a flake or filler with a unidirectional arrangement of hydrophilic and hydrophobic layers. The flakes are mixed so that the portion closest to the body is higher in aromatic waterproof fiber material and the portion further from the body is lower in content. This design, characterized by different hygroscopic properties on the front and back sides, creates a unidirectional moisture-wicking system, facilitating the removal of moisture.

[0048] The non-woven down filling is made by directly mixing aromatic waterproof down with untreated down (non-functional down or ordinary down); the mass ratio of aromatic waterproof down to untreated down is 5-20:95-80.

[0049] The nonwoven cotton / silk batting is constructed using a three-layer process: the silk batting is alternating between aromatic waterproof fibers and untreated fibers, with the innermost layer closest to the body positioned. The inner layer contains 5-20% aromatic waterproof fibers, the middle layer 10-15% aromatic waterproof fibers, and the outer layer 0-10% aromatic waterproof fibers. Gauze is added to the surface of the pure cotton batting and then polished to create a smooth, non-slip surface, minimizing fiber leakage. After the silk is spread, it is covered with non-woven fabrics, knitted fabrics, gauze, or other fabrics to prevent fiber leakage. The batting can have a grammage of 100-350gsm.

[0050] The nonwoven production method for viscose / chemical fiber floss is as follows: the floss is divided into three layers. Aromatic waterproof staple fibers and untreated staple fibers are mixed and carded. After carding, the three thin floss layers with varying proportions are stacked and then ironed or polished to form the finished floss. The inner layer, closest to the body, consists of 10-25% aromatic waterproof staple fibers and 10-20% low-melting-point polyester fibers; the middle layer has 10-20% aromatic waterproof staple fibers and 10-20% low-melting-point polyester fibers; and the outer layer has 0-10% aromatic waterproof staple fibers and 10-20% low-melting-point polyester fibers. These proportions are by weight and are based on the grammage of the floss. After laying, the chemical fiber floss can be ironed at 110-140°C to create a surface seal and reduce fiber leakage. For example, the floss weight ranges from 60-450 gsm and the thickness ranges from 5-40 mm.

[0051] Furthermore, the present invention provides the use of the aforementioned aromatic textile filler in functional home textile products.

[0052] The aromatic textile filling obtained in the embodiments of the present invention can be added to fabrics to produce functional home textile products. The aromatic down filling is preferably added to down-proof fabrics, such as polyester-cotton down-proof fabrics, pure cotton down-proof fabrics, or viscose-cotton down-proof fabrics. The non-skin-facing fabric should have better water absorption than the skin-facing fabric, and the double-layer fabric and down should form a moisture-wicking effect. According to QB / T 1193-2012 "Down and Feather Quilts," down-proof fabrics should have an air permeability of 5-25 mm / s and a down count of less than 20. The aromatic silk cotton batting or wadding can be added to non-down-proof fabrics and quilted to produce a finished, aromatic product.

[0053] In a preferred embodiment of the present invention, after washing, the finished fragrance product is dried in a dryer or hung on a steamer under steam after drying, and the temperature can be 60-110°C to promote the waterproof effect of the waterproof finishing agent and improve the washability.

[0054] The embodiments of the present invention use down, silk, chemical fiber, cotton, etc. as filling fiber materials, which are finished with aromatic microcapsules, waterproofed, and then designed with a one-way moisture-conducting structure to obtain a textile filling with aromatic sustained release, water resistance, and moisture-removal. When in use, after friction / squeezing, the aromatic essential oil in the microcapsules is released, which can have the effect of reducing pressure and relieving mood.

[0055] The aromatic textile filler product described in the embodiment of the present invention has the following advantages: the use of aromatic microcapsules has the characteristic of slow release, which can increase the storage time of essential oils. After waterproofing, it can not only improve the hygroscopicity of the filler and reduce the discomfort of using the filler in a humid environment, but also reduce the time that the aromatic microcapsules are in contact with water during washing, thereby reducing the shedding of microcapsules after washing. During compounding, the content of aromatic waterproof fiber material is high in the part close to the human body, and low in the part away from the human body, forming a unidirectional moisture-conducting dehumidification system, which is more conducive to the discharge of moisture / water. In addition, after washing, the product of the present invention needs to be dried to increase the fastness of the waterproofing agent and increase the number of washing times that the waterproofing agent can withstand, which is more conducive to the long-term existence of the aromatic microcapsules.

[0056] In order to better understand the technical content of the present invention, specific examples are provided below to further illustrate the present invention. In the following examples, the aromatic finishing agent is: the BAYSCENT series microcapsules of Tona used in the market. The fixing agent is a hydroxy acrylic resin with a molecular weight of 6200-8000, and the relative molecular weight of hydroxyl groups accounts for 1-3%. The penetrant is JFC; the adhesive is sodium isocyanate or isocyanate water-based bridging agent. The waterproofing agent uses Daikin's TG product and Tona's bio-based fluorine-free waterproof finishing agent. LTR 01.

[0146] As demonstrated in the above examples, the aromatic fillings described herein possess a certain degree of waterproofing and a unidirectional moisture-conducting structure. Not only do their aromatic microcapsules slowly release fragrance upon friction or compression, but they also improve the filling's hygroscopicity, reducing discomfort during use during the rainy season. Furthermore, they reduce the time the aromatic microcapsules remain in contact with water during washing, minimizing the loss of microcapsules during washing. Furthermore, they form a unidirectional moisture-conducting system, further facilitating the removal of moisture. The aromatic textile fillings described herein, when used in bedding sets, increase the added value of textiles, provide consumers with a high-quality lifestyle, and expand market potential. They are expected to find widespread application in functional home textiles and apparel.
