Product Description
Introduction to Aramid 13: Aramid 13, also known as meta - aramid, is scientifically named poly (m - phenylene isophthalamide). It is a flexible polymer. Its breaking strength is higher than that of common polyester, cotton, nylon, etc. It has a relatively high elongation rate, a soft hand - feel, and good spinnability. It can be produced into short fibers and filaments with different fiber fineness and lengths, and then woven into different fabrics to meet the requirements of protective clothing in different fields.
Characteristics Brought by Spunlaced Process
Closely Entangled Fibers: The spunlaced process punctures the fibers with high - pressure water jets, causing the fibers to entangle with each other. As a result, the fiber structure of the meta - aramid 13 spunlaced non - woven fabric is tight. It doesn't shed fibers or delaminate easily and has good integrity. When used to make filtering materials, this tight structure can effectively intercept tiny particles and ensure the filtering effect.
Good Air Permeability: Compared with some non - woven fabrics reinforced by chemical bonding and other methods, spunlaced non - woven fabrics have better air permeability. This is because the pores between the fibers are relatively unobstructed and air can flow freely. In application scenarios such as wound dressings in the medical field or sportswear, good air permeability helps to keep the skin dry and comfortable.
Good Absorbency: Because the spunlaced process makes the fibers interweave to form a rich pore structure, the meta - aramid 13 spunlaced non - woven fabric also has a certain absorbency. In the medical field, it can absorb the exudate from wounds. In the field of cleaning products, it can better adsorb stains and so on.
Advantages
Closely Entangled Fibers and Good Strength
The spunlaced process punctures the fibers with high-pressure water jets, making the fibers entangle with each other. As a result, the fiber structure of the spunlaced non-woven fabric is tight, and it has good strength and integrity. For example, when wiping objects with a certain degree of roughness on the surface, it is not easily damaged and can withstand a certain amount of friction.
Compared with the thermal-bonded non-woven fabric, the thermal-bonded non-woven fabric melts the hot-melt fibers on the fibers by heating to bond other fibers together. This method may have a certain impact on the performance of the fibers during the heating process, while the spunlaced non-woven fabric avoids this problem and the original properties of its fibers can be better preserved.
Good Softness and Drapeability
The spunlaced non-woven fabric has a soft hand feel. This is because the way its fibers are entangled is relatively natural, without adding too many chemical adhesives or undergoing complicated mechanical treatments that would make it hard. When making clothing, home textiles and other products, this softness can provide a more comfortable touch.
It also has good drapeability and can naturally conform to the shape of the human body or objects. For example, when making medical surgical gowns, the spunlaced non-woven fabric can fit well with the body movements of medical staff without causing any obstruction.
Excellent Air Permeability
The pores between the fibers of the spunlaced non-woven fabric are relatively unobstructed, allowing air to flow freely. This makes its air permeability better than that of many other non-woven fabrics. In the field of sportswear, athletes will generate a large amount of sweat and heat during exercise. The spunlaced non-woven fabric can timely discharge the heat and moisture, keeping the skin dry and improving the wearing comfort.
Compared with SMS (spunbond-meltblown-spunbond) non-woven fabric, although SMS non-woven fabric has certain protective properties, due to its multi-layer structure and the existence of some meltblown layers, its air permeability is relatively poor, while the spunlaced non-woven fabric has an obvious advantage in this regard.
Good Absorbency
The spunlaced process makes the fibers interweave to form a rich pore structure, which endows the spunlaced non-woven fabric with good absorbency. In the aspect of medical dressings, it can effectively absorb the exudate from wounds and promote wound healing.
In the cleaning field, for example, when used to wipe liquid stains, it can absorb a certain amount of liquid and has a better absorption effect than ordinary needle-punched non-woven fabric, because the pore structure of the needle-punched non-woven fabric is relatively less regular and its ability to absorb liquid is slightly weaker.
Good Environmental Protection
The spunlaced process usually does not involve the use of a large amount of chemical adhesives. Compared with chemically bonded non-woven fabric, it produces less chemical pollution during the production process. Moreover, after being discarded, due to its relatively simple composition, the spunlaced non-woven fabric has less potential harm to the environment.
Disadvantages
Relatively Low Production Efficiency
The spunlaced process relies on high-pressure water jets to puncture and entangle the fibers. This process is relatively complicated, and the production speed is slower than that of some other non-woven fabric production processes (such as the needle-punching reinforcement process of needle-punched non-woven fabric). This leads to a certain limitation on the output of the spunlaced non-woven fabric, and the production cost may increase due to the low production efficiency.
Slightly Poor Dimensional Stability
In a humid environment, the spunlaced non-woven fabric may change in size due to the absorption of moisture. For example, the spunlaced non-woven fabric products stored in an environment with high humidity may expand and deform, while thermal-bonded non-woven fabric or needle-punched non-woven fabric after special post-treatment may perform better in terms of dimensional stability.
Insufficient Strength in Some Extreme Situations
