Technical Field

[0001] The utility model provides an anti-curling polypropylene non-woven fabric, and relates to the technical field of non-woven fabrics. Background Art

[0002] Non-woven fabric is made of polyester fiber and polyester fiber and is made through a needle-punching process. It can be made into different thicknesses, feels, hardness, etc. Non-woven fabric is moisture-proof, breathable, flexible, thin, flame-retardant, non-toxic and odorless, inexpensive, and recyclable. It can be used in different industries, such as sound insulation, heat insulation, electric heaters, masks, clothing, medical, filling materials, etc.

[0003] After being stored for a long time, the edges of existing non-woven fabrics tend to curl, making it difficult to flatten them when they are needed. It takes a lot of time to process them, resulting in reduced work efficiency.

[0004] Therefore, it is necessary to provide an anti-curling polypropylene non-woven fabric, which can strengthen the edge of the fabric by setting an anti-curling hemming so that the edge of the non-woven fabric is not easy to curl. Utility Model Content

[0005] In order to overcome the shortcomings of existing non-woven fabrics that the edges of the fabrics are prone to curling after being placed for a long time and require a long time to be leveled, the utility model provides an anti-curling polypropylene non-woven fabric, which strengthens the edges of the fabric by setting an anti-curling edging so that the edges of the non-woven fabric are not easy to curl.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model provides the following technical solution: an anti-curling polypropylene non-woven fabric, comprising a polypropylene base layer and a flame-retardant fiber layer, the flame-retardant fiber layer is coated on the polypropylene base layer, and also comprises an anti-curling edging, and the edges of each surface of the polypropylene base layer are coated with the anti-curling edging.

[0007] As a further preferred solution, the anti-roll edging is made of canvas.

[0008] As a further preferred embodiment, the flame retardant fiber layer is made of a blend of one or more of glass fiber, chlorofluorocarbon fiber, and aromatic sulfone fiber.

[0009] As a further preferred embodiment, the flame retardant fiber layer accounts for 20%-30% of the total composition.

[0010] As a further preferred embodiment, a waterproof layer is also included which is coated on the flame retardant fiber layer.

[0011] As a further preferred embodiment, it also includes a hot melt adhesive layer and a wear-resistant layer, wherein the hot melt adhesive layer is coated on the waterproof layer, and the wear-resistant layer is attached to the hot melt adhesive layer.

[0012] As a further preferred solution, the wear-resistant layer is made of nylon.

[0013] As a further preferred embodiment, the wear-resistant layer accounts for 15%-25% of the total composition.

[0014] Compared with the prior art, the nonwoven fabric provided by the embodiment of the utility model has the following advantages: 1. The edge strength of the nonwoven fabric is enhanced by anti-curling hemming, so that the edge of the nonwoven fabric will not curl.

[0015] 2. The waterproof layer can block the intrusion of water, preventing water from penetrating the fabric and getting people wet, thus making the nonwoven fabric waterproof.

[0016] 3. The wear resistance of the outer surface of the nonwoven fabric is enhanced by the wear-resistant layer to prevent the fabric from being damaged due to scratches and friction, thereby achieving the effect of making the nonwoven fabric wear-resistant. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0022] Example 1: A kind of anti-curling polypropylene nonwoven fabric, see Figure 1-Figure 3 As shown, it includes a polypropylene base material layer 1 and a flame retardant fiber layer 3. The flame retardant fiber layer 3 is attached to the polypropylene base material layer 1. The flame retardant fiber layer 3 is made of a blend of one or more of glass fiber, chlorofiber fiber, and aromatic sulfone fiber. The flame retardant fiber layer 3 accounts for 20%-30% of the total component. It also includes an anti-roll edging 2. The edges of each surface of the polypropylene base material layer 1 are coated with the anti-roll edging 2. The anti-roll edging 2 is made of canvas, and the canvas has a relatively stable structural strength.

[0023] When the nonwoven fabric is used to make a finished product, the flame-retardant fiber layer 3 can retard the flame to prevent the polypropylene base material layer 1 from burning; when the nonwoven fabric is placed for a long time, the anti-curling edging 2 can enhance the edge strength of the nonwoven fabric to prevent the edge of the nonwoven fabric from curling.

[0024] Example 2: Based on Example 1, refer to Figure 2 and Figure 3 As shown, it also includes a waterproof layer 4 coated on the side of the flame retardant fiber layer 3 away from the polypropylene base material layer 1.

[0025] When using clothing made of the nonwoven fabric, the waterproof layer 4 can block the intrusion of water, preventing water from penetrating the fabric and wetting the person.

[0026] See also Figure 2 and Figure 3 As shown, it also includes a hot melt adhesive layer 5 and a wear-resistant layer 6. The hot melt adhesive layer 5 is coated on the side of the waterproof layer 4 away from the flame retardant fiber layer 3. The side of the hot melt adhesive layer 5 away from the waterproof layer 4 is covered with the wear-resistant layer 6 for enhancing wear resistance. The wear-resistant layer 6 is made of nylon, and the wear-resistant layer 6 accounts for 15%-25% of the total component.

[0027] The hot melt adhesive layer 5 is used to connect the wear-resistant layer 6 to the waterproof layer 4. The wear-resistant layer 6 can enhance the wear resistance of the outer surface of the non-woven fabric and prevent the fabric from being damaged due to scratches and frictions.
