Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to a non-woven fabric based on biological micro-fragrance technology. Background Art

[0002] Non-woven fabrics, also known as nonwovens, non-woven fabrics or non-woven fabrics, are materials made of directional or randomly arranged fibers through friction, cohesion, bonding or a combination of these methods. They are usually used for surgical gowns, protective clothing, disinfection wraps, masks, diapers, civilian wipes, wipes, wet face towels, magic towels, soft towel rolls, beauty products, sanitary napkins, sanitary pads and disposable sanitary cloths, etc.

[0003] When using existing non-woven fabrics, users usually use incense to make the fragrance evaporate and penetrate into the gaps between the clothing fibers to achieve the purpose of retaining the fragrance. Later, perfumes were invented and these were sprinkled on clothing. However, the fragrance effects obtained by these methods are short-lived and poorly lasting, which reduces the comfort of the fabric.

[0004] In order to overcome the above-mentioned defects, the prior art (application number: 201320555973.2, Chinese patent application date: September 2, 2013) discloses a scented cloth composite substrate for clothing. The scented cloth composite substrate has a reasonable structural design, is easy and flexible to process, and can be pasted on clothing to emit a fragrant smell, effectively eliminate odor and be antibacterial.

[0005] Although the existing technology can solve the problem of achieving the fragrance effect of the scented cloth composite substrate, since the adhesive bottom layer is made of hot melt adhesive or self-adhesive adhesive, although it is easy to paste, the temperature generated by the hot melt adhesive during the hot pressing process can easily damage the clothes, and the self-adhesive adhesive may not have strong enough adhesion, so it is easy to fall off during disassembly, resulting in poor fragrance effect. In addition, the scented cloth composite substrate does not have breathable, waterproof, anti-corrosion and heat-insulating functions, which reduces the comfort of the non-woven fabric.

[0006] Therefore, we proposed a non-woven fabric based on biological micro-aroma technology that can solve the above problems well. Utility Model Content

[0007] The purpose of the utility model is to provide a non-woven fabric based on biological micro-fragrance technology to solve the problem raised in the above background technology that a non-woven fabric based on biological micro-fragrance technology currently on the market is made of hot-melt adhesive or self-adhesive adhesive when in use. Although it is easy to paste, the temperature generated by the hot-melt adhesive during the hot pressing process can easily damage the clothes, and the self-adhesive adhesive may not have strong enough adhesion, so it is easy to fall off during disassembly, resulting in poor fragrance effect, and the composite base material of the fragrance cloth does not have breathable, waterproof, anti-corrosion and heat-insulating functions, which reduces the comfort of the non-woven fabric.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a non-woven fabric based on biological micro-aroma technology, comprising a non-woven fabric body, wherein the non-woven fabric body comprises a base fabric layer, a middle layer, a micro-aroma layer, a breathable layer, a surface layer, a waterproof layer and an inner lining layer;

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1-6 , the utility model provides the following technical solutions:

[0033] Example 1: In order to solve the problem that a non-woven fabric based on biological micro-fragrance technology on the market is easy to paste when in use, because the adhesive bottom layer is made of hot melt adhesive or self-adhesive adhesive, the temperature generated by the hot melt adhesive during the hot pressing process is easy to damage the clothes, and the self-adhesive adhesive may have insufficient adhesion, so it is easy to fall off during disassembly, resulting in poor fragrance effect. Figure 1 -Attached Figure 3 and attached Figure 6The nonwoven fabric comprises a base fabric 1, comprising a base fabric layer 2, a middle layer 3, a micro-aroma layer 4, a breathable layer 5, a surface layer 6, a waterproof layer 7, and an inner lining layer 8. The micro-aroma layer 4 comprises a first shell 9 and a second shell 10, each of which has a first core 11, a second core 12, a third core 13, and a fourth core 14 formed on its inner wall. The first shell 9 and the second shell 10 are woven together, and both are made of natural polymer materials. A variety of fragrance mixture gases are deposited on the inner walls of the first core 11, the second core 12, the third core 13, and the fourth core 14, encapsulating them within the first shell 9 or the second shell 10. The first core 11, the second core 12, the third core 13, and the fourth core 14 are sized to be 100-200 microns.

The first capsule wall shell 9 and the second capsule wall shell 10 are made of natural polymer materials and have good biocompatibility and degradability. When the first capsule wall shell 9 and the second capsule wall shell 10 are subjected to external force (such as friction, extrusion), or when the temperature rises and causes the capsule wall material to melt, the first capsule wall shell 9 and the second capsule wall shell 10 will rupture, so that the fragrance gas in the first capsule core 11, the second capsule core 12, the third capsule core 13 and the fourth capsule core 14 in the first capsule wall shell 9 and the second capsule wall shell 10 is gradually released, and the released gas is transferred to the surface layer 6 through the breathable layer 5, so that the entire non-woven fabric has the effect of microbial fragrance, thereby realizing the effect of microbial fragrance of the non-woven fabric.

[0035] Example 2: The non-woven fabric can be made breathable, waterproof, anti-corrosion and heat-insulating. Figure 1 -Attached Figure 2 and attached Figure 4 -Attached Figure 5 The non-woven fabric body 1 is provided with a base fabric layer 2 inside. The top of the base fabric layer 2 is bonded to a middle layer 3. The top of the middle layer 3 is bonded to a micro-aroma layer 4.

The bottom of the base fabric layer 2 is hot-pressed to a waterproof layer 7. The bottom of the waterproof layer 7 is hot-pressed to an inner lining layer 8. The middle layer 3 includes a fiber layer 15 and an adhesive layer 16. The fiber layer 15 is provided inside the middle layer 3. The upper and lower connections of the fiber layer 15 are bonded to the adhesive layer 16. There are two adhesive layers 16, and the two adhesive layers 16 are tightly bonded to the base fabric layer 2 and the waterproof layer 7. The waterproof layer 7 is made of polypropylene. The surface layer 6 is made of polyester fiber, and the upper surface of the surface layer 6 is provided with a pattern layer.

[0036] A fiber layer 15 is provided in the middle layer 3, which is made of bamboo fiber material and has good air permeability, moisture absorption and antibacterial properties, thereby increasing the comfort of the non-woven fabric and releasing the fragrance gas through ventilation. The waterproof layer 7 made of polypropylene fiber is tightly combined with the base fabric layer 2, which can effectively block the penetration of moisture while maintaining the air permeability of the non-woven fabric, thereby achieving waterproofness without causing internal moisture. The inner lining layer 8 is made of polyethylene material and has anti-corrosion, waterproof and heat-insulating effects, thereby further increasing the waterproof effect, making the non-woven fabric breathable, waterproof, anti-corrosion and heat-insulating, and improving the comfort of the non-woven fabric.
