[0002] Polyester pongee fabric is an old variety that has been on the market for a long time, but in recent years the textile industry has revised its products. In addition to using matte silk raw materials and innovating weaving technology, it has also extended the post-dyeing and finishing process. Its density has increased, the feel has become softer, and its functions have been expanded.
[0003] The existing polyester pongee fabric has poor hygroscopicity. Poly pongee fabric is often in a dry environment. In the dry winter environment, the polyester pongee fabric rubs against fabrics such as sweaters worn in winter, which easily generates static electricity due to friction. The static electricity charge is difficult to effectively conduct away from the fabric in a dry environment. Static electricity can irritate human skin and even generate sparks during friction with clothing, affecting the comfort of wearing clothes. Utility Model Content
[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an antistatic polyester pongee fabric, which solves the problem that the existing polyester pongee fabric is prone to generate static electricity through structural settings.

The side walls of the moisturizing sheet are respectively against the bottom surface of the moisturizing groove and the side wall of the inner layer facing the outer layer. The moisturizing sheet is fixedly connected between the inner layer and the outer layer by a hygroscopic yarn. The moisturizing sheet is formed by twisting and cutting several strands of hygroscopic yarn. Under 20 degrees Celsius, the moisture regain of the hygroscopic yarn is 65% RH (3.0%-5.0%), 95% RH (10.0%-12.0%).
[0006] The utility model is further configured as follows: the hygroscopic yarn is twisted from strong FDY vinylon fiber, and the twist of the hygroscopic yarn is 12 twists.

[0017] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.
[0018] An antistatic polyester pongee fabric, such as Figures 1 to 3As shown, it includes an inner layer 1 and an outer layer 2 fixedly connected to each other, a plurality of moisturizing grooves 4 are opened on the side wall of the outer layer 2 facing the inner layer 1, and a plurality of moisturizing grooves 4 are opened in an array on the side wall of the outer layer 2 facing the inner layer 1, and the positions where the moisture-absorbing yarn 3 is connected to the inner layer 1 and the moisture-absorbing yarn 3 is connected to the outer layer 2 are staggered, so that the moisture-absorbing yarn 3 can extend to different positions of the spring polyester spun fabric to expand the influence range of the moisture-absorbing yarn 3, and the moisture-absorbing yarn 3 fixes a plurality of moisturizing sheets 5 in the moisturizing groove 4 during sewing and threading, and a plurality of moisturizing grooves 4 are formed on the outer layer 2 by hot pressing with a hot press, and a plurality of moisturizing grooves 4 are arranged in an array on the outer layer 2, and the horizontal cross-section of the moisturizing groove 4 is circular, and a circular moisturizing sheet 5 is fixedly connected to the bottom of the moisturizing groove 4, and the circular moisturizing sheet 5 makes the contact part between the moisture-absorbing yarn 3 and the inner layer 1 and the outer layer 2 of the fabric not only limited to the moisture-absorbing yarn 3 itself threaded between the inner layer 1 and the outer layer 2 of the fabric, so that the circular moisturizing sheet 5 can increase the moisture-absorbing yarn 3 on the surface The contact area between the inner layer 1 and the outer layer 2 of the material, the diameter of the moisturizing sheet 5 is equal to the diameter of the moisturizing groove 4, and the side walls of the moisturizing sheet 5 are respectively against the bottom surface of the moisturizing groove 4 and the side wall of the inner layer 1 facing the outer layer 2, so that the moisturizing sheet 5 and the inner layer 1 and the outer layer 2 remain in a relatively static state, reducing the relative friction inside the spring polyester spun fabric and reducing the charge generated by friction. The moisturizing sheet 5 is fixedly connected between the inner layer 1 and the outer layer 2 by the hygroscopic yarn 3. The moisturizing sheet 5 is formed by twisting and cutting several strands of hygroscopic yarn 3. The hygroscopic yarn 3 is fixedly connected to the moisturizing sheet 5, so that after the hygroscopic yarn 3 absorbs moisture, the area of the moisturized area on the spring polyester spun fabric is expanded through the passage formed by the moisturizing sheet 5 and the hygroscopic yarn 3. The hygroscopic yarn 3 is connected from the side of the inner layer 1 away from the outer layer 2 to the side of the outer layer 2 away from the inner layer 1, so that the moist hygroscopic yarn 3 can quickly and effectively conduct the charge generated at various positions in the spring polyester spun fabric, thereby avoiding the accumulation of charge in the spring polyester spun fabric.
[0019] like Figures 1 to 3 As shown, the hygroscopic yarn 3 is formed by twisting strong FDY vinylon fiber through a twisting machine. The hygroscopic yarn 3 is made by spinning strong FDY vinylon fiber. Under 20 degrees Celsius, the moisture regain of the hygroscopic yarn 3 is 65% RH (3.0%-5.0%), 95% RH (10.0%-12.0%). By changing the moisture regain of the spring polyester spun fabric, the spring polyester spun fabric has higher hygroscopicity in daily use, and the moisture generated by human sweat is absorbed into the hygroscopic yarn 3 in time, so that the inner layer 1 and the outer layer 2 are maintained in a relatively humid environment, so that the charge generated by friction in the spring polyester spun fabric is conducted out of the spring polyester spun fabric through the moist hygroscopic yarn 3, avoiding the accumulation of a large amount of charge inside the spring polyester spun fabric to produce an electrostatic effect, thereby improving the wearing comfort.
[0020] like Figure 1 , Figure 3As shown, the outer layer 2 is formed by feeding the wear-resistant yarn into the air-jet loom and weaving it in a plain weave manner, the wear-resistant yarn is twisted by a twisting machine to twist polyester fiber, and the twist of the wear-resistant yarn is 6 twists, the inner layer 1 is formed by feeding the comfortable yarn into the air-jet loom and weaving it in a plain weave manner, the comfortable yarn is twisted by a twisting machine to twist spandex fiber, and the twist of the comfortable yarn is 12 twists, the inner layer 1 and the outer layer 2 are fixed by sewing the moisture-absorbing yarn 3 through the inner layer 1 and the outer layer 2 by a sewing machine, and the moisture-absorbing yarn 3 is passed through the inner layer 1 and the outer layer 2 and is reciprocated and sewn. The twist of the wet yarn 3 is 12 twists, the 12-twist hygroscopic yarn 3 is a strong twist yarn, and the 6-twist wear-resistant yarn is a weak twist yarn. The strong twist yarn will have relatively less exposed hairiness, and the weak twist yarn will have relatively more exposed hairiness. In the formed spring polyester fabric, the weak twist wear-resistant yarn will adhere to the strong twist hygroscopic yarn 3 and the comfortable yarn, thereby reducing the relative friction between the inner layer 1 and the outer layer 2, reducing the number of charges generated by friction, and achieving the effect of reducing the possibility of electrostatic effect.
[0021] like Figure 1 , Figure 2 As shown, the wet strength of fiber refers to the maximum tensile force that the fiber can withstand when it is at saturated humidity, and the relative wet strength refers to the tensile breaking strength of the fiber per unit linear density (per tex or per denier) measured in a wet state. Setting the relative wet strength of the strong FDY vinylon fiber to 75%-90% can ensure that the hygroscopic yarn 3 has sufficient strength for normal wearing when maintained at a high humidity.
[0022] like Figure 1 , Figure 2 As shown, the yarn count of the hygroscopic yarn 3 is smaller than the yarn count of the wear-resistant yarn and the yarn count of the comfortable yarn. The thinner hygroscopic yarn 3 is conducive to interlacing and weaving in the wear-resistant yarn and the comfortable yarn. The yarn count of the wear-resistant yarn and the yarn count of the comfortable yarn are both 90D. The 90D wear-resistant yarn and the 90D comfort yarn are both relatively thick. The thicker wear-resistant yarn carries more fluff and the thicker comfort yarn carries more fluff, so that the inner layer 1 and the outer layer 2 have more fluff, and the spring polyester fabric has better warmth retention performance. The yarn count of the hygroscopic yarn 3 is 150D. The 150D hygroscopic yarn 3 has a thinner yarn count, which is convenient for stitching and interlacing the inner layer 1 and the outer layer 2 with the hygroscopic yarn 3.
[0023] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
