82%Nylon 18%Spandex Bio-based Nylon Fabric

Description

Compared with traditional petroleum-derived nylon, bio-based nylon has longer alkyl chains and a lower melting point, between 180-195 degrees Celsius.

Therefore, although the tensile strength and modulus of bio-based nylon are not as high as those of traditional nylon, their processing temperature is low, energy consumption is low, and their longer alkyl chains make bio-based nylon have lower water absorption, much higher impact strength, and better toughness than traditional nylon.

Industrial corn and straw are used as raw materials to extract starch glucose, which is then fermented into lysine. Lysine is then converted into pentamethylenediamine using process technology. Pentamethylenediamine is reacted with adipic acid to obtain Bio-based nylon 56 with a bio-based content of 48%.

In this series of operations, obtaining bio-based pentamethylenediamine is the most important. This production process is carried out under normal temperature and pressure conditions, so it can achieve very low water consumption, energy consumption, and emissions.

Bio-based nylon 56 has a unique molecular structure. Its unsaturated hydrogen bonds can keep the fabric naturally active, making it more flexible, heat-resistant, and dry.

Moisture-wicking and dry

The moisture regain of Bio-based nylon 56 fiber is much lower than that of cotton fiber and cellulose fiber, but at the same time, higher than that of polyester fiber. Therefore, the constant moisture regain of Bio-based nylon 56 can not only keep the fabric dry and avoid moisture retention, but also reduce the itching and static electricity caused by excessive dryness.

Moreover, Bio-based nylon 56 has a high thermal conductivity, and its heat conduction is faster than that of PA66, so it feels cool when worn. Some clothing merchants also use it in home textile four-piece sets, which have achieved very good sales results.

Flexibility

The unsaturated hydrogen bonds in the Bio-based nylon 56 molecular chain can provide the fabric with strong and wear-resistant properties. At the same time, the natural and soft touch and drape are also excellent.

This makes the fabric suitable for outdoor sports, underwear, yoga wear, jackets, and military applications.

If blended with wool or silk, it will be more wear-resistant and cost less, but the feel of wool will not be greatly reduced.

Bright Colors

Bio-based nylon 56 has many molecular gaps. The increase in the molecular chain spacing makes it easier for dyes to enter, so the coloring is fast, deep, and bright. The desired dyeing effect can be achieved at a lower temperature and pressure, which reduces the energy consumption of dyeing and saves dyes.
