Description

Flame-retardant polyester fabric with excellent tear resistance

Technical Field

The utility model relates to a technical field of fire-retardant surface fabric, in particular to anti fire-retardant dacron that tear performance is good.

Background

Fire is one of the main disasters that threaten public safety and social development most often and most generally, and fire prevention is the central importance of disaster prevention. Various fabrics are widely used in daily life and are also main combustible materials. The use of the cloth having flame retardant properties, such as curtains, tents, protective clothing, etc., can solve the problem of the cloth getting on fire from the source.

Chinese patent No. CN208829842U discloses a tear-resistant flame-retardant environment-friendly curtain fabric, which comprises a base cloth formed by interweaving warps and wefts, wherein a first fireproof layer and a waterproof layer are sequentially arranged on one side of the base cloth, and a second fireproof layer is arranged on the other side of the base cloth; the warp comprises a first carbon fiber yarn positioned on the core, the first carbon fiber yarn is spirally wound with a first yarn and a second yarn, and the first yarn and the second yarn are both cotton fiber yarns; the weft comprises a second carbon fiber yarn positioned in the core, a third yarn and a fourth yarn are spirally wound on the second carbon fiber yarn, the rotating directions of the third yarn and the fourth yarn are opposite, and the third yarn and the fourth yarn are both glass fiber yarns.

Because glass belongs to inorganic materials and cannot be combusted, the tear-resistant flame-retardant environment-friendly curtain fabric uses the glass fiber yarns as the third yarns and the fourth yarns, and the glass fiber yarns are spirally wound on the second carbon fiber yarns to form wefts of the base fabric, so that the flame retardance of the curtain fabric can be effectively improved.

On the other hand, glass fibers are brittle and have poor abrasion resistance, and when used as a fabric, they are easily broken during repeated folding and stretching. Therefore, after the tear-resistant flame-retardant environment-friendly curtain fabric is used for a period of time, the weft of the tear-resistant flame-retardant environment-friendly curtain fabric is broken and loosened in a large area, and the tear resistance is poor.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): a flame-retardant polyester fabric with excellent tear resistance is disclosed, which comprises an inner liner 4, a room-temperature vulcanized silicone rubber layer 5, a base fabric 1, a high-temperature vulcanized silicone rubber layer 3, a shaping layer 2 and a flame-retardant layer 6, wherein the structures are sequentially arranged according to the figure 1.

Referring to fig. 1, the lining 4 is woven by flax fiber, and the thickness is slightly less than one third of the thickness of the base cloth 1. The lining 4 is used as a cloth inner layer, has good touch feeling and enhances the comfort of a user.

Referring to fig. 1, the room temperature vulcanized silicone rubber layer 5 is filled between the lining 4 and the base fabric 1 to adhere the lining 4 and the base fabric 1 together, and has good elasticity and uniform deformation in the fabric stretching process.

Referring to fig. 1, the base fabric 1 is woven with warp threads 11 and weft threads 12, wherein the weft threads 12 are provided in a wave shape along the length direction of the weft threads 12. When the fabric is stretched and deformed in the longitudinal direction of the weft 12, the weft 12 is gradually spread and the degree of undulation is reduced. The actual length of the weft thread 12 does not change until the weft thread 12 is fully deployed.

Referring to fig. 2, the warp 11 is formed by twisting one first yarn 111 and eight second yarns 112, and the twist of the warp 11 is 700-900T/m. The first yarn 111 is made of terylene, the second yarn 112 is made of cotton fiber yarn, and the cotton fiber yarn is treated by soaking the flame retardant liquid.

Referring to fig. 3, the weft 12 is formed by twisting one third yarn 121 and three fourth yarns 122, and the twist of the weft 12 is 500-700T/m, wherein the third yarn 121 is made of polyester, and the fourth yarn 122 is made of glass fiber yarn.

Referring to fig. 1, a high temperature vulcanized silicone rubber layer 3 is adhered to a base fabric 1, and fitted with a room temperature vulcanized silicone rubber layer 5 to completely fill the depressions on the surface of the base fabric 1. In addition, the high-temperature vulcanized silicone rubber layer 3 also has good elasticity, and is uniformly deformed in the cloth stretching process, so that the weft 12 is uniformly spread.

Referring to fig. 1, the sizing layer 2 is woven by carbon fiber and copper ammonia fiber, has high strength and toughness, and can protect the structures such as the base cloth 1 and the lining 4 on the inner side of the sizing layer 2. The high-temperature vulcanized silicone rubber layer 3 adheres the base cloth 1 and the sizing layer 2 together, so that the weft threads 12 keep a wave-shaped structure.

Referring to fig. 1, the flame retardant coating 6 is formed by drying and curing the flame retardant liquid coated on the outer surface of the setting layer 2, and has a certain flame retardant effect.

In this example, the composition of the flame retardant liquid is as follows: 5-8 parts of silicon dioxide aerogel, 2-5 parts of expanded vermiculite, 2-3 parts of cyclic phosphate ester, 2-5 parts of thickening agent, 3-5 parts of nano antimony tin oxide, 10-20 parts of waterborne polyurethane, 5-10 parts of pentaerythritol, 2-4 parts of glucose grafted soybean protein and 100-150 parts of distilled water.

The specific implementation process comprises the following steps:

when the fabric is stretched and deformed in the longitudinal direction of the weft 12, the weft 12 is gradually spread and the degree of undulation is reduced. The actual length of the weft thread 12 does not change until the weft thread 12 is fully deployed. Therefore, the glass fiber yarn constituting the weft 12 is not easily broken, so that the cloth maintains good tear resistance during long-term use.
