Viscose non woven fabric is a popular choice in many industries due to its versatility, absorbency, and relatively low cost. However, one common issue that some users face is that it can sometimes feel a bit rough. As a viscose non woven fabric supplier, I've dealt with this concern quite a bit. In this blog, I'll share some tips on how to make viscose non woven fabric softer.
Understanding Viscose Non Woven Fabric
Before we dive into the softening methods, let's quickly understand what viscose non woven fabric is. Viscose is a semi-synthetic fiber made from wood pulp. Non woven means the fabric is made by bonding or interlocking fibers together, rather than weaving or knitting them. This results in a fabric that's strong, absorbent, and easy to produce.
We offer different types of viscose non woven fabric, such as Spunlace Viscose Non Woven Fabric, Absorbent Non Woven Fabric, and Perforated Non Woven Fabric. Each type has its own unique properties and uses, but all can benefit from being softened.
Softening Methods
1. Chemical Softeners
One of the most common ways to make viscose non woven fabric softer is by using chemical softeners. These are substances that can be applied to the fabric during the manufacturing process or after it's been produced.
There are two main types of chemical softeners: cationic and non - ionic. Cationic softeners are positively charged and tend to provide a good softening effect. They can also improve the fabric's antistatic properties. However, they may not be suitable for all types of viscose non woven fabric, especially those that will come into contact with sensitive skin.
Non - ionic softeners, on the other hand, are more neutral and are generally considered safer for use on fabrics that will be in direct contact with the body. They work by coating the fibers of the fabric, reducing friction between them, and making the fabric feel smoother.
When using chemical softeners, it's important to follow the manufacturer's instructions carefully. Too much softener can make the fabric greasy or reduce its absorbency.
2. Mechanical Treatments
Mechanical treatments can also help to soften viscose non woven fabric. One such treatment is brushing. Brushing the fabric can loosen the fibers on the surface, making it feel softer to the touch. This can be done using a special brushing machine during the manufacturing process or by hand for smaller quantities.
Another mechanical treatment is calendering. Calendering involves passing the fabric through a series of heated rollers under pressure. This can smooth out the fabric surface, reduce any roughness, and give it a softer finish. However, calendering needs to be done at the right temperature and pressure to avoid damaging the fabric.
3. Moisture and Conditioning
Viscose non woven fabric can become stiffer when it's dry. Adding moisture to the fabric can help to make it softer. You can do this by spraying the fabric with water or by exposing it to a humid environment.
After adding moisture, it's a good idea to condition the fabric. Conditioning can be done by using a fabric conditioner or a natural substance like vinegar. Vinegar can help to break down any residual chemicals on the fabric and make it softer. Simply mix a small amount of vinegar with water and spray it on the fabric. Then, let it dry naturally.
4. Blending with Other Fibers
Blending viscose with other softer fibers can also improve the overall softness of the non woven fabric. For example, blending viscose with cotton can result in a fabric that combines the absorbency of viscose with the softness of cotton.
Other fibers that can be blended with viscose include silk and bamboo. Silk is known for its luxurious softness, while bamboo fibers are naturally smooth and gentle on the skin. The ratio of viscose to the other fibers will depend on the desired properties of the final fabric.
Quality Control and Testing
Once you've applied a softening method to the viscose non woven fabric, it's important to test the fabric to ensure that it meets your softness requirements. You can do a simple touch test to feel the difference in softness before and after the treatment.
For more accurate results, you can use a fabric softness tester. These devices measure the fabric's bending stiffness and can provide a numerical value for its softness. Regular quality control and testing will help you to maintain a consistent level of softness in your viscose non woven fabric.
Conclusion
Making viscose non woven fabric softer is achievable through a variety of methods, including chemical softeners, mechanical treatments, moisture and conditioning, and blending with other fibers. As a viscose non woven fabric supplier, I'm always happy to help customers find the best solution for their specific needs.
