What is the relationship between functional fabrics and functional fibers?

Are functional fabrics only used for the outdoors and for sports? How can we choose the functional fabrics with real functional value from the many so-called "functional fabrics"? In the following discussion, we will explore the perception of functional fabrics and fibers

Functional fiber is a sufficient and unnecessary condition for functional fabrics. The functional needs of the fabric can also be achieved after finishing. In this case, brands and Manufacturers consider the efficiency, durability, and cost of functionality. In terms of cost comparison, when meeting the functional requirements of the demand, the production cost is calculated through the production process of both, so as to choose a more economical production mode.

The cost of using functional yarn includes: functional yarn + weaving + dyeing + conventional finishing. The cost of finishing after use includes: ordinary yarn + weaving + dyeing + conventional finishing + functional finishing (usually additives).

It also has something to do with the textile methods.

What is the difference between ordinary fiber and functional fiber? Is there a difference in appearance?

Understanding the production process, in fact, the relationship between functional fabrics and functional fibers is actually very simple. The functional fiber is woven into a variety of styles of fabric, then this fabric is functional. Thats why functional fabrics are not similar to conventional fabrics in most cases. Most functional fibers adopt the principle of blending, which changes their properties by blending with functional mother particles. At present, most functions are realized through such physical modification. There are also a few ways that they open the fiber molecular chains and add functional groups. For example, hydrophilic polyester, is through the addition of hydrophilic groups to improve the return rate of ordinary polyester, to solve the pain point of ordinary polyester hot heat. Of course, such a process also has defects and faces challenges in dyeing.

However, functional fabrics are not only made of functional fibers, but also can improve their performance by finishing ordinary fabrics.

After the whole with flame retardant potion. Will such a thing last well? The wash is gone.

Yes, but it can actually be flame retardant with the fiber and the whole rear. There are three main reasons here:

1. Cost

2. Permanent

3. Application scenarios

First, we can look at the cost composition of both. Use functional yarn: functional yarn + weaving + dyeing + conventional finishing. Use of finishing: ordinary yarn + weaving + dyeing + conventional finishing + functional finishing (usually additives). What you will consider is whether the cost of functional yarn is lower than the cost of ordinary yarn + functional finishing.

Second, look at the permanent. Most of the additives are not permanent, washed more times, they become ineffective. Yarn, as long as it does not damage the structure of the fabric, is theoretically permanent. For example, curtains, these textile products with low washing frequency, do not have to use functional yarn to do it, because it may increase unnecessary costs.

Does using functional fiber instead of finishing change the style of the fabric? Thats why functional areas such as outdoor and sports prefer functional fabrics. And the fashion and leisure fields that pay more attention to design and fabric texture are not used much because of the limitations of functional fabrics.

Using functional fibers in the vast majority of cases does not change the style of the fabric. Due to the nature of the fiber, some functional fibers will have an influence on the color, color fastness, strength, etc.

How to identify whether a piece of fabric has real functionality through the test report?

The most direct way to judge the functional fabrics is to judge whether the product is real and has functional utility through the commodity tags. According to the "National Technical Specification for Basic Safety of Textile Products", the clothing tag must contain the fiber composition and content, product implementation standard number, product quality grade products and other 8 contents. The tag is only suitable to distinguish non-functional fabrics and functional fabrics, in order to screen those poor quality, business false propaganda "false functional fabrics". How to judge the two functional fabrics that meet the national standards need to rely on the functional test report to judge.

That is, if a piece of clothing emphasizes that it has some functional characteristics, there will be a separate tag.

Yes, like Uniqlos Dry-Ex series. Like the Gore-Tex.

Will some businesses themselves privately hang up, the relevant departments check is not strict.

The possibility is not ruled out, and some businesses may take advantage of the loopholes in the system, but there is a risk of being reported by consumers and professional counterfeiters.

Functional tags are separate, and ordinary clothing tags are different properties. The ordinary clothing tag shows that the product meets the national quality standards, while the functional tag is to prove that the product reaches the national standard in a certain function. Chinas national standard in the functional products set up the standard threshold in the world is lso one of the strictest standards. Even in some function of the index requirements in the first position. The functional products that have passed Chinas national standard are also widely recognized around the world.

That our GB belongs to the best standard in the international?

There is no good or bad standard. The difference between the standards is that each country has different requirements for the test methods and test standards of the same function.

Reliable verification method, is it necessary to see the test report?

Most of the testing reports are made by third-party testing institutions to make authoritative evaluation of the functionality of fabrics in a neutral, objective and scientific way. Is the most reliable method to validating functional products.
