Products Description
Diacetate tow is a high-performance fiber material with high strength, good heat resistance, and wear resistance. It is widely used in aerospace, automotive industry, textile and clothing and other fields, and is one of the indispensable important materials in modern industry.
Imagine if you have a super strong rope that can not only pull a car, but also remain unchanged at high temperatures. This rope is the diacetate tow we are talking about today!
Diacetate tow is a high-performance fiber made of diacetate cellulose filaments after special treatment. It is not only strong, but also particularly heat-resistant, and can maintain good performance even in high temperature environments. Moreover, its wear resistance and chemical corrosion resistance are also excellent, it is simply a "superhero fiber".
So, what are the uses of such a powerful material? First of all, in the field of aerospace, diacetate tow is used to make internal structural parts of aircraft, such as floor beams, seat frames, etc., which are both light and strong, and can effectively reduce the weight of the aircraft and improve flight efficiency.
Secondly, in the automotive industry, it is used to make fabrics for airbags. This fabric is not only strong, but also has good energy absorption effect, which can protect the safety of passengers at critical moments.
In the field of textiles and clothing, diacetate fiber tow is also used to make high-end underwear, socks and other close-fitting clothing. Its soft feel and good breathability make the wearer feel very comfortable.
In addition, diacetate fiber tow is also widely used in many fields such as electronics and electrical, architectural decoration, etc. It can be said that it is an indispensable part of our lives, silently providing us with help and protection.
Products useage
The tobacco silk ribbon is a long strip-like fiber bundle formed by bundling and curling a large number of continuous long fibers for processing into tobacco filter rods. Currently, the two most widely used types are cellulose acetate silk ribbons and polypropylene silk ribbons. Cellulose acetate silk ribbons are made from natural cellulose acetate fibers and are used to roll acetate fiber filter rods. Polypropylene fiber silk ribbons are made from polypropylene resin and are used to roll polypropylene silk ribbon filter rods, but their inhalation performance and filtration efficiency are inferior to the traditional cellulose acetate filter rods. Due to the high price and difficulty in obtaining cellulose acetate silk ribbons, counterfeit cigarettes often use polypropylene silk ribbons as the filter rod material. Therefore, the type of silk ribbon is an important characteristic for identifying the authenticity of cigarettes.
The cellulose acetate filament is mainly used as a cigarette filter tip. This is mainly because the filter tip made of cellulose acetate filament has the advantages of low resistance during inhalation, good smoke filtration effect, and the ability to selectively adsorb harmful components in the smoke. The cellulose acetate filament is mainly produced by the dry spinning process: the weighed cellulose acetate sheets are dissolved in acetone, and through stirring, a spinning solution is formed. The spinning solution is filtered, degassed, and then enters the spinning channel. The spinning stream solidifies into a filament strip through heat flash evaporation in the channel. The filament strip is wound into a filament bundle by the winding roller, and then undergoes curling, drying, rewinding, and packaging [1].
However, during the production process of cellulose acetate filament, some products that do not meet quality standards and filament that has not been sold within a certain period of time will be treated as waste filaments. These products will be stored in the waste filament warehouse and await subsequent re-dissolution and spinning. However, the processability is the most fundamental issue in all fiber spinning processes. Processability is particularly important in dry spinning. During dry spinning, the focus is on spinning under conditions close to the maximum jet stretching, while minimizing the occurrence of filament breakage to achieve continuous and high-speed production. Rheological properties are a performance that provides guidance for processability. Whether different storage times will have an impact on the physical indicators related to the filament and processability has not been reported in any relevant literature so far.
