Description

Technical Field

[0001] The utility model relates to the technical field of textile fabrics, and more specifically, to a flame-retardant polyester-cotton fabric. Background Art

[0002] Polyester-cotton refers to a blend of polyester and cotton, commonly known as "Dacron," made from 65%-67% polyester and 33%-35% cotton yarn. It is a common material used in clothing.

[0003] When polyester-cotton blended fabrics burn, the carbonization of the cotton fibers acts like a candle wick for the polyester, hindering the escape of polyester droplets and making the flame difficult to extinguish. Furthermore, the mutual thermal induction between the polyester and cotton polymers or their cracking products accelerates the overflow of the cracking products, leading to a faster ignition rate. Therefore, a structure is needed to address the poor flame retardancy of polyester-cotton fabrics.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a flame retardant polyester-cotton fabric.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: the flame-retardant polyester-cotton fabric includes a base layer, a flame-retardant layer is fixedly connected to one side of the base layer, a plurality of cross-arranged receiving grooves are opened on the flame-retardant layer, the receiving grooves separate the flame-retardant layer into a plurality of partition pieces, and the receiving grooves are filled with polyurethane flame-retardant foam material.

[0007] The utility model is further configured such that: the height of the polyurethane foam material after molding is higher than the height of the partition piece.

[0008] The present invention is further configured such that: the distances between two adjacent accommodating grooves are equal, and the cross-sectional shape of the partition piece is square.

[0009] The utility model is further configured as follows: the partition piece is woven by polyester yarn.

[0010] The utility model is further configured as follows: a TPU flame retardant film is fixedly connected between the base layer and the flame retardant layer.

[0011] The utility model is further configured as follows: the base layer is configured as a plain weave, the base layer is woven by polyester yarn and cotton yarn, and the weaving ratio of the polyester yarn to the cotton yarn is 5:2.

[0012] In summary, the present invention has the following beneficial effects:

[0013] The flame retardant layer can protect the base layer and reserve time for fire to damage the base layer so that people can put out the fire in time, thereby increasing the service life of the base layer. The partition pieces divided by the receiving groove reduce the area of the flame retardant layer in a region, and the connection between adjacent partition pieces is reduced through the receiving groove. At the same time, a TPU flame retardant film is fixedly connected between the base layer and the flame retardant layer. The TPU flame retardant film not only has flame retardant properties, but also has good elasticity and wear resistance, and is more suitable for adding to fabrics, making flame retardant fabrics more practical.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0018] The flame retardant polyester-cotton fabric, such as Figure 1-Figure 2 As shown, it includes a base layer 1, which supports the additional structure on the entire fabric to ensure the overall strength of the structure. A flame retardant layer is fixedly connected to one side of the base layer 1, and a number of cross-arranged receiving grooves 2 are opened on the flame retardant layer. The receiving grooves 2 separate the flame retardant layer into a number of partition pieces 3. The flame retardant layer is arranged on the outer side of the base layer 1. When a fire occurs, the flame retardant layer first contacts the fire source. The flame retardant layer can protect the base layer 1, and can reserve time for the fire to damage the base layer 1 so that people can put out the fire source in time, thereby improving the service life of the base layer 1. The partition pieces 3 divided by the receiving grooves 2 reduce the area of the flame retardant layer in a region, and the connection between adjacent partition pieces 3 is reduced by the receiving grooves 2. When one of the partition pieces 3 burns, there is no combustible material between the adjacent partition pieces 3 to achieve the effect of blocking the continuous combustion of the flame retardant layer, thereby improving the flame retardant effect of the flame retardant layer. At the same time, a TPU flame retardant film 5 is fixedly connected between the base layer 1 and the flame retardant layer. The TPU flame retardant film 5 not only has flame retardant properties, but also has good elasticity and wear resistance, and is more suitable for adding to fabrics, making the flame retardant fabric more practical.

[0019] like Figure 1-Figure 2As shown, the receiving groove 2 is filled with a polyurethane flame retardant foam material 4. The height of the polyurethane foam material after molding is higher than the height of the partition piece 3. Although the receiving groove 2 can form a safe area between adjacent partition pieces 3, when the flame is high, it will still affect the adjacent partition pieces 3. Therefore, the polyurethane flame retardant foam material 4 filled in the receiving groove 2 has good flame retardant and heat-resistant properties, further blocking the expansion of the fire source, and the polyurethane flame retardant foam material 4 is higher than the height of the receiving groove 2. The polyurethane flame retardant foam material 4 is wrapped on the outer peripheral wall of the partition piece 3 to protect the partition piece 3 and enhance the flame retardant effect of the fabric.

[0020] like Figure 1-Figure 2 As shown, the distance between two adjacent receiving grooves 2 is equal, and the cross-sectional shape of the partition piece 3 is square, so that the receiving groove 2 separates the flame retardant layer more evenly. The number of receiving grooves 2 is increased while controlling the cost to achieve a better flame retardant effect. The partition is woven with polyester yarn. The polyester yarn will melt when exposed to fire but will not burn. Under the enclosure of the polyurethane flame retardant foam material 4, the polyester yarn will only melt in this area, which also achieves the purpose of preventing the expansion of the burning range.

[0021] like Figure 1-Figure 2 As shown, the base layer 1 is set to a plain weave, and the base layer 1 is woven by polyester yarn and cotton yarn. The weaving ratio of polyester yarn and cotton yarn is 5:2. The polyester yarn has high structural strength, and the cotton yarn has a soft texture and good moisture absorption. The base layer 1 will be more comfortable when in contact with the body surface, and the high proportion of polyester yarn strengthens the structural strength of the base layer 1. The base layer 1 woven by the plain weave is smoother.

[0022] like Figure 1-Figure 2 As shown, the polyester yarn and the cotton yarn are threaded and fixed on the water jet loom in a 5:2 arrangement pattern, and the weft is also woven according to this ratio to form the base layer 1. The TPU flame retardant film 5 is laminated and fixed on the base layer 1 under the processing of the laminating machine. The flame retardant layer woven with polyester yarn is fixed to the side of the base layer 1 where the TPU flame retardant film 5 is provided. The laser cutting machine cuts on the flame retardant layer to form a number of receiving grooves 2 and a partition piece 3 formed by dividing the receiving grooves 2. Finally, the polyurethane flame retardant foam material 4 is filled in the receiving groove 2 by a filling machine or manually. After expansion, the polyurethane flame retardant foam material 4 protrudes from the flame retardant layer.

[0023] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
