Hygroscopicity of polyester ammonia double fabric: limitations and ways to improve it

In today's textile market, polyester ammonia double fabric has won the favor of many consumers with its unique blended material and double-layer structure. However, just as everything has its two sides, polyester ammonia double fabric shows certain limitations in terms of hygroscopicity, which also affects its wearing comfort and application range to a certain extent.

First, let's talk about the hygroscopicity of polyester fiber. Polyester, as a synthetic fiber, has relatively poor hygroscopicity. This means that when the human body sweats, polyester fiber cannot absorb and dissipate sweat as quickly as natural fibers, but allows sweat to remain on the surface of the skin, causing the skin to feel sticky. This discomfort is particularly obvious during strenuous exercise or high temperature environments. In polyester ammonia double fabric, polyester fiber is one of the main components, and its lack of hygroscopicity naturally has a negative impact on the hygroscopicity of the entire fabric.

Let's look at the hygroscopicity of spandex fiber. Spandex, known for its excellent elasticity, is an indispensable part of polyester ammonia double fabric. However, similar to polyester fibers, spandex fibers also have weak hygroscopicity. This further limits the performance of polyester ammonia double fabrics in terms of hygroscopicity. When sweat cannot be absorbed and dissipated by the fabric in time, the comfort of the wearer will be greatly reduced.

So, facing the limitations of polyester ammonia double fabrics in terms of hygroscopicity, how should manufacturers deal with it? In fact, some effective methods have been applied in actual production.

A common method is to add hygroscopic agents. These special chemicals can form a thin layer of coating on the surface of the fiber, thereby improving the hygroscopicity of the fabric. When sweat contacts the fabric, this coating can quickly absorb the sweat and diffuse it to other parts of the fabric, speeding up the evaporation of sweat and making the wearer feel drier and more comfortable. However, it should be noted that the addition of hygroscopic agents may increase production costs and have a certain impact on other properties of the fabric (such as breathability, durability, etc.). Therefore, the amount of addition and the treatment process need to be carefully controlled during the production process.

Another method is to adjust the fiber ratio. By increasing the proportion of fibers with better hygroscopicity (such as cotton, bamboo fiber, etc.), the hygroscopicity of polyester ammonia double fabric can be improved to a certain extent. However, this method also has some problems. On the one hand, increasing the proportion of other fibers may change the original properties of the fabric (such as elasticity, wear resistance, etc.); on the other hand, the blending ratio between different fibers needs to be determined through rigorous experiments and tests to ensure that the overall performance of the fabric reaches the best state.
