Description

Preparation process of a hygroscopic, heat-generating, antibacterial, antistatic and thermal insulation acetic acid fabric

Technical field

The invention belongs to the field of functional fabrics and relates to a preparation process of a hygroscopic, heat-generating, antibacterial, antistatic and heat-insulating acetic acid fabric.

Background technique

When manufacturing fabrics, people usually consider many factors, such as the texture, strength, softness, durability, and comfort of the fabric. However, as people have higher and higher requirements for the performance of textiles, moisture wicking and moisture absorption and heat generation with antibacterial properties have become more and more important factors.

In the past, many fabrics had unsatisfactory moisture-wicking, moisture-wicking and antibacterial properties. For example, some traditional fiber materials such as cotton and wool can absorb a large amount of moisture, but they take a long time to dry, and they also lack moisture wicking and moisture absorption and heat generation properties. Some synthetic fibers such as polyester and nylon can dry faster, but they lack the ability to absorb moisture and generate heat. In addition, many fabrics are prone to harbor bacteria and microorganisms, leading to problems such as odor and infection.

In recent years, Naia diethyl acetate fiber developed by Eastman Company has become a fiber material that has attracted much attention. Naia diacetate fiber is a cellulose fiber made from sustainable raw material wood pulp. Naia fiber has many small pores and microfibers, which can quickly absorb sweat and moisture and evaporate them quickly, thus keeping the human body Dry and comfortable, Naia fiber has excellent moisture-wicking and moisture-wicking properties thanks to its fiber structure and chemical properties. At the same time, Naia fiber also has antibacterial properties, which can effectively inhibit the growth of bacteria and microorganisms and avoid problems such as odor and infection.

For Naia diacetate fiber, if we can make use of its characteristics to maximize its strengths and avoid weaknesses, during the spinning stage, add modal and acrylic fibers to neutralize and strengthen its characteristics, so that it has: moisture wicking, moisture absorption and heating properties, antibacterial properties, antistatic and Thermal insulation performance can perfectly solve the problem of lack of moisture-absorbing, heat-generating, antibacterial, antistatic, and thermal insulation fabrics on the market.
