Description

Technical Field

[0001] The invention belongs to the technical field of down products, and particularly relates to a universal scented down inner core. Background Art

[0002] Down jacket lining is one of the most important factors affecting the warmth retention of down jackets. It is generally made of a double-layer fabric composite to lock in the down. The corresponding down core is made of the above materials and is widely used in down jackets, duvets and other textiles. However, due to the different physical constitutions of different people, for example, some people have body odor, and the covering of down products in winter can lead to embarrassing incidents. Therefore, people have a greater demand for scented down cores.

[0003] Existing scented fabrics are primarily based on microencapsulation technology. By encapsulating essential oils in microcapsules, friction between fabrics or between fabrics and skin during wear causes the microcapsules to rupture, resulting in a sustained release of the fragrance. Furthermore, the essential oils in these scented fabrics are absorbed through human respiration, potentially providing certain medicinal benefits. For example, patent publication number CN105200802B discloses a method for preparing a lightweight, scented wool fabric with health benefits. The method includes fabric preparation, post-processing, freezing, and anti-wrinkle finishing with frankincense microcapsules. The present invention pre-freezes wool fabric and then pads it with a frankincense microcapsule anti-wrinkle finishing liquid. After the freezing treatment, the internal spaces within the fibers of the wool fabric are enlarged, the anti-wrinkle finishing liquid penetrates deeply into the internal spaces within the fibers, the adhesion between the polyurethane resin and the wool fabric is enhanced, and frankincense is incorporated into the wool fabric in the form of microcapsules. By utilizing the characteristics of frankincense being brittle at low temperatures, soft at high temperatures, and swelling upon contact with water, the sustained-release time of the frankincense microcapsules can be extended, thereby imparting a long-lasting fragrance and health-care function to the wool fabric. Although the fabric has the long-lasting fragrance and health-care function, how to maximize the effect of the fragrance fabric after combining it with a down inner core remains a question to be studied. In addition, the existing down inner core has poor fluffiness, making it difficult to maximize the function of the fragrance fabric. Summary of the Invention

[0004] The purpose of the present invention is to provide a universal scented down inner core with good fluffiness, excellent warmth retention and the ability to maximize the effect of scented fabric in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A universal scented down inner core comprises a first liner sewn from an outer fabric and a second liner sewn from a scented fabric, a thermal insulation space for the distribution of the first down being formed between the inner surface of the outer fabric and the outer surface of the scented fabric, expansion fibers being evenly distributed in the thermal insulation space, a second down being arranged inside the second liner, the filling amount of the second down being greater than the filling amount of the first down, the expansion fibers comprising elastic fibers made of fully matte polyester filament fibers and hollow composite fibers, the elastic fibers being provided with a spiral recess, and the two free ends of the elastic fibers being respectively connected to the inner surface of the outer fabric and the outer surface of the scented fabric.

[0007] As a further optimization scheme of the present invention, according to the mass percentage: the elastic fiber is twisted by 30%-40% full-dull polyester filament fiber and 60%-70% hollow composite fiber, wherein the full-dull polyester filament fiber has high elasticity, and the elastic fiber made of full-dull polyester filament fiber is equipped with a spiral depression, so that the elasticity of the overall elastic fiber is greatly increased. On the one hand, when the first liner is pressurized, the elastic fiber will be compressed and release the air inside the first liner, the second liner and the warm-keeping space. The air passes through the fragrance fabric and releases the internal odor of the fragrance fabric, which is convenient for rapid release. When the first liner is pressurized and rebounds, the elasticity of the elastic fiber causes the area between the fragrance fabric and the outer fabric to be stretched. At this time, the warm-keeping space will expand rapidly and fill with a large amount of air, avoiding long-term pressure on the first down and the second down, resulting in uneven distribution of the down, thereby ensuring the overall warmth retention of the inner core. Whether the inner core is used to make a down jacket or a down quilt, it has good fluffiness and warmth retention.

[0008] On the other hand, the full-dull polyester filament fiber and the hollow composite fiber cooperate with each other. The full-dull polyester filament fiber greatly enhances the overall ductility of the hollow composite fiber. When the first inner liner is compressed and rebounds, the aromatic smell emitted by the fragrance fabric flows back along the internal space of the hollow composite fiber to the interior of the second inner liner. While ensuring the emission of aromatic smell, it can effectively absorb a certain amount of aromatic smell, thereby increasing the concentration of aromatic smell in the second inner liner to a certain extent, ensuring the sustainable use of the aromatic fabric, and greatly extending the service life of the aromatic fabric. On the other hand, it will not release a large amount of aromatic smell at one time, is not pungent or unpleasant, and can effectively ensure the even and slow release of aromatic smell. When made into a down quilt, it can effectively guarantee the user's sleep quality.

[0009] As a further optimization scheme of the present invention, the hollow composite fiber is compounded with PTT, low-viscosity PET, expansion particles and stabilizer slices in a ratio of 50:35:10:5, and is made by a ring-blowing cooling device. The cross-section of the hollow composite fiber is a circular hollow structure. The fiber made by mixing PTT and low-viscosity PET has high toughness. The expansion particles are integrated with PTT and low-viscosity PET, so that the overall thermal expansion effect of the hollow composite fiber formed by PTT and low-viscosity PET is good. When the hollow composite fiber is heated and expanded, it will quickly expand the thermal insulation space, making the volume of the thermal insulation space The volume of the thermal insulation space rapidly increases. On the one hand, the expansion of the thermal insulation space greatly enhances the overall thermal insulation. On the other hand, after the thermal insulation space expands, the hollow composite fiber extends along the spiral depression. At this time, the first down located in the thermal insulation space is adsorbed on the spiral depression, which plays a role in evenly distributing the first down in the thermal insulation space, avoiding uneven distribution of the first down, and further ensuring the thermal insulation of the first liner. On the other hand, after the thermal insulation space expands, the second liner will also expand. Therefore, the second down inside the second liner will expand rapidly, thereby further enhancing the thermal insulation of the second liner.

[0010] In addition, the setting of the stabilizer, on the one hand, enhances the degree of fusion between PTT, low-viscosity PET and expanded particles, and on the other hand, greatly enhances the ductility and elasticity of PTT and low-viscosity PET.

[0011] As a further optimization scheme of the present invention, several groups of pores are provided on the inner wall of the hollow composite fiber; when the hollow composite fiber expands and extends, the aromatic smell will overflow along the pores and fill the internal space of the warm space, and the aromatic smell will overflow along the internal holes of the outer fabric, so as to slowly release the aromatic smell and further improve the comfort of the user. On the other hand, after the pores are expanded, the air permeability of the fabric is greatly enhanced, and the comfort is good. When the hollow composite fiber shrinks and folds, the pores are in a closed state, which can effectively reduce heat loss and enhance thermal insulation.

[0012] As a further optimization solution of the present invention, the expansion particles are thermoplastic polymer particles or gel particles; the expansion particles expand when heated, and are used to enhance the ductility and elasticity of the expansion fiber.

[0013] As a further optimization solution of the present invention, the stabilizer is rubber; rubber as a stabilizer has strong ductility and is convenient for enhancing the degree of fusion between PTT, low-viscosity PET and expanded particles.

[0014] As a further optimization scheme of the present invention, the fragrance fabric is based on microcapsule technology and is obtained by encapsulating the fragrance raw materials in microcapsules; when worn, the friction between the first inner liner and the second inner liner causes the microcapsules to rupture, achieving a sustained release effect, so that the fabric has a relatively long-lasting fragrance release effect.

[0015] As a further optimization scheme of the present invention, the aromatherapy raw materials include 50%-60% rosin and 40%-50% volatile oil; the aromatherapy raw materials of the scented fabric are absorbed through human breathing and can achieve certain medicinal functions. When the aromatherapy raw materials are heated, the volatile oil will drive the rosin to evaporate and pass through the internal pores of the hollow composite fiber and be evenly distributed inside the warm space.

[0016] The beneficial effects of the present invention are as follows: by providing full-dull polyester filament fibers and hollow composite fibers, the full-dull polyester filament fibers greatly enhance the overall ductility of the hollow composite fibers; when the first inner liner is compressed and rebounds, the aromatic odor emitted by the fragrance fabric flows back into the interior of the second inner liner along the internal space of the hollow composite fibers; while ensuring the emission of the aromatic odor, a certain amount of aromatic odor can be effectively absorbed, thereby increasing the concentration of the aromatic odor in the second inner liner to a certain extent, ensuring the sustainable use of the fragrance fabric, and greatly extending the service life of the fragrance fabric; on the other hand, a large amount of aromatic odor is not released at one time, and the fragrance is not pungent or unpleasant, and the uniform and slow release of the aromatic odor can be effectively guaranteed; when made into a down quilt, the user's sleep quality can be effectively guaranteed, the fluffiness is good, the warmth retention is excellent, and the fragrance fabric can be used to the greatest extent;

[0017] In addition, by arranging a second liner inside the first liner and filling the second liner with the first down and the second liner with the second down respectively, the heat preservation of the entire liner can be effectively ensured. In addition, by imitating the "cell nucleus" structure, on the one hand, the first liner is used to protect the second liner, and on the other hand, the first and second liner are filled with down in different areas, which has high heat preservation.

[0018] Furthermore, the internal filling volume of the second liner is higher than that of the first liner. When the down core is under pressure, the second liner will rebound quickly, and the second liner will quickly lock in heat and have a good thermal insulation effect. In addition, the first liner will play a role of buffering protection and can well protect the outside of the first liner. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example

[0026] like Figure 1-3 As shown, a universal scented down core comprises a first liner 2 sewn from an outer fabric 1 and a second liner 4 sewn from a scented fabric 3. A warming space 5 for the distribution of the first down 7 is formed between the inner surface of the outer fabric 1 and the outer surface of the scented fabric 3. By arranging the second liner 4 inside the first liner 2, and filling the second down 8 and the first down 7 inside the second liner 4 and the first liner 2 respectively, the thermal insulation of the entire liner can be effectively ensured. In addition, by imitating the "cell nucleus" structure, on the one hand, the first liner 2 is used to protect the second liner 4, and on the other hand, the first liner 2 and the second liner 4 are filled with down in different areas, which has high thermal insulation.

[0027] In addition, the expansion fibers 6 are evenly distributed in the warm-keeping space 5, and the second down 8 is provided inside the second liner 4. The filling amount of the second down 8 is greater than the filling amount of the first down 7. The filling amount inside the second liner 4 is higher than the filling amount inside the first liner 2. When the down core is under pressure, the second liner 4 will rebound quickly, and the second liner 4 will play a role of quickly locking heat, and the thermal insulation effect is good. In addition, the first liner 2 plays a role of buffering protection, and the first liner 2 can well protect the outside of the first liner 2.

[0028] The expansion fiber 6 includes an elastic fiber 61 made of full-dull polyester filament fiber 611 and a hollow composite fiber 612. The elastic fiber 61 is provided with a spiral recessed portion 62. The two free ends of the elastic fiber 61 are respectively connected to the inner surface of the outer fabric 1 and the outer surface of the fragrance fabric 3.

[0029] According to the percentage by mass: the elastic fiber 61 is twisted by 30% full-dull polyester filament fiber 611 and 70% hollow composite fiber 612, wherein the full-dull polyester filament fiber 611 has high elasticity. The elastic fiber 61 made of full-dull polyester filament fiber 611 is matched with the spiral concave portion 62, which greatly increases the elasticity of the entire elastic fiber 61. On the one hand, when the first liner 2 is pressurized, the elastic fiber 61 will be compressed and release the first liner 2, the second liner 4 and the inner part of the warm space 5. The air passes through the fragrance fabric 3, releasing the odor inside the fragrance fabric 3, facilitating quick release. When the first liner 2 is compressed and rebounds, the elasticity of the elastic fiber 61 causes the area between the fragrance fabric 3 and the outer fabric 1 to be stretched. At this time, the warm space 5 will expand rapidly and be filled with a large amount of air, avoiding long-term compression of the first down and the second down, resulting in uneven distribution of the down, thereby ensuring the overall warmth retention of the inner core. Whether the inner core is used to make a down jacket or a down quilt, it has good fluffiness and warmth retention.

[0030] On the other hand, the fully matte polyester filament fiber 611 and the hollow composite fiber 612 cooperate with each other. The fully matte polyester filament fiber 611 greatly enhances the overall ductility of the hollow composite fiber 612. When the first inner liner 2 is compressed and rebounds, the aromatic smell emitted by the fragrance fabric 3 flows back along the internal space of the hollow composite fiber 612 to the interior of the second inner liner 4. While ensuring the emission of aromatic smell, it can effectively absorb a certain amount of aromatic smell, thereby increasing the concentration of aromatic smell in the second inner liner 4 to a certain extent, ensuring the sustainable use of the fragrance fabric 3, and greatly extending the service life of the fragrance fabric 3. On the other hand, it will not release a large amount of aromatic smell at one time, is not pungent or unpleasant, and can effectively ensure the uniform and slow release of aromatic smell. When made into a down quilt, it can effectively ensure the user's sleep quality.

[0031] The hollow composite fiber 612 is compounded with PTT, low-viscosity PET, expansion particles and stabilizer slices in a ratio of 50:35:10:5, and is made by a ring-blowing cooling device. The cross-section of the hollow composite fiber 612 is a circular hollow structure. The fiber made by mixing PTT and low-viscosity PET has high toughness. The expansion particles are integrated with PTT and low-viscosity PET, so that the overall thermal expansion effect of the hollow composite fiber 612 formed by PTT and low-viscosity PET is good. When the hollow composite fiber 612 is heated and expanded, it will quickly expand the thermal insulation space 5, causing the volume of the thermal insulation space 5 to rapidly increase. On the one hand, the thermal insulation The expansion of the space 5 greatly enhances the overall warmth retention. On the other hand, after the warmth retention space 5 is expanded, the hollow composite fibers 612 extend along the spiral recessed portion 62. At this time, the first down 7 located in the warmth retention space 5 is adsorbed on the spiral recessed portion 62, which plays a role in uniformly distributing the first down 7 in the warmth retention space 5, thereby avoiding uneven distribution of the first down 7 and further ensuring the warmth retention of the first liner 2. On the other hand, after the warmth retention space 5 is expanded, the second liner 4 is also expanded. Therefore, the second down 8 inside the second liner 4 expands rapidly, thereby further enhancing the warmth retention of the second liner 4.

[0032] In addition, the setting of the stabilizer, on the one hand, enhances the degree of fusion between PTT, low-viscosity PET and expanded particles, and on the other hand, greatly enhances the ductility and elasticity of PTT and low-viscosity PET.

[0033] like Figure 4 As shown, a plurality of groups of pores 613 are provided on the inner wall of the hollow composite fiber 612; when the hollow composite fiber 612 expands and extends, the aromatic smell will overflow along the pores 613 and fill the inner space of the thermal insulation space 5, and the aromatic smell will overflow along the inner holes of the outer fabric 1, so as to slowly release the aromatic smell and further improve the comfort of the user. On the other hand, after the pores 613 are expanded, the air permeability of the fabric is greatly enhanced, and the comfort is good. When the hollow composite fiber 612 shrinks and folds, the pores 613 are in a closed state, which can effectively reduce the loss of heat and enhance the thermal insulation.

[0034] The expansion particles are thermoplastic polymer particles; the expansion particles expand when heated, and are used to enhance the ductility and elasticity of the expansion fiber 6 .

[0035] The stabilizer is rubber; as a stabilizer, rubber has strong ductility and is convenient for enhancing the degree of fusion between PTT, low-viscosity PET and expanded particles.

[0036] The fragrance fabric 3 is based on microcapsule technology and is obtained by encapsulating fragrance raw materials in microcapsules; when worn, the friction between the first liner 2 and the second liner 4 causes the microcapsules to rupture, achieving a sustained release effect, so that the fabric has a relatively long-lasting fragrance release effect.

[0037] The aromatherapy raw materials include 60% rosin and 40% volatile oil. The aromatherapy raw materials of the scented fabric are absorbed through human breathing and can achieve certain medicinal functions. When the aromatherapy raw materials are heated, the volatile oil will drive the rosin to evaporate and pass through the internal pores 613 of the hollow composite fiber 612 and be evenly distributed inside the warm space 5.

[0038] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
