What is water-soluble non woven fabric？

Water-soluble nonwoven fabrics can be used to make embroidery base fabrics, applique clothes, leaflets, printed materials, etc.

Characteristics of water-soluble nonwoven fabrics

Water-soluble non-woven fabrics are a special non-woven material with excellent permeability and solubility. It can dissolve in water, does not cause environmental pollution, and has strong biodegradability, so it is a green and environmentally friendly product. There are many specifications of water-soluble non-woven fabrics, and different materials can be selected according to different needs.

Raw material selection

The main raw material of water-soluble non-woven fabrics is polyvinyl alcohol (PVA) staple fibers. Short fibers are usually produced by direct spinning and slicing, and then assembled into water-soluble non-woven fabrics by spinning. When selecting raw materials, factors such as fiber length, strength, and thickness need to be considered to ensure that the quality of the produced water-soluble non-woven fabrics meets the standard requirements.

 Production process

The production process of water-soluble non-woven fabrics includes: raw material processing, solution preparation, spinning, water immersion, drying, winding and other links. Among them, the preparation of the solution is one of the key processes, and it is necessary to control the concentration, temperature, pH value and other indicators of the solution to ensure the stable quality of the produced water-soluble non-woven fabric. In addition, in the spinning, water immersion and other processes, it is also necessary to control the relevant parameters to ensure that the quality of the water-soluble non-woven fabric meets the standards.

 Equipment used

The equipment for producing water-soluble non-woven fabrics mainly includes rotary spinning machines, water immersion tanks, drying racks, etc. The rotary spinning machine is one of the most core equipment in the entire production process, and its performance is crucial to the quality of water-soluble non-woven fabrics. When using the equipment, it is necessary to pay attention to the cleaning and maintenance of the equipment to extend the service life of the equipment.

Quality control

The quality control of water-soluble non-woven fabrics is an important means to ensure product quality. Its core lies in monitoring and testing various indicators of the product. Common quality control methods include appearance quality inspection, physical property testing, sedimentation water resistance testing, etc. By adopting effective quality control methods, the quality level of water-soluble non-woven fabrics can be effectively improved to meet the needs of users in different industries.

Uses of water-soluble nonwoven fabrics

1. Embroidery base fabric

Water-soluble non-woven fabrics can be used to make embroidery base fabrics. Draw the embroidery pattern on the water-soluble non-woven fabric, and then perform embroidery processing. After the embroidery is completed, soak the embroidery base fabric in water, and the water-soluble non-woven fabric will automatically dissolve, leaving only the exquisite embroidery work.

2. Applique clothes

Water-soluble non-woven fabrics can also be used to make applique clothes. Draw patterns such as flowers and animals on water-soluble non-woven fabrics, and then cut them off. Put the clothes on a flat plate, use an iron to stick the water-soluble non-woven fabric on the clothes, and then put the applique clothes in water. The water-soluble non-woven fabric will automatically dissolve, leaving only the exquisite applique.

3. Leaflets and printed materials

Water-soluble non-woven fabrics can also be used to make leaflets and printed materials. Print the pattern to be printed on the water-soluble non-woven fabric, and then stick it on the material to be printed for printing. After printing is completed, soak the printed matter in water, and the water-soluble non-woven fabric will automatically dissolve, leaving only the exquisite printed matter.

Conclusion

Water-soluble non-woven fabric is a very practical material with a wide range of applications, including medical and health care, household cleaning, industrial filtration and many other fields. However, to ensure that the quality of the products produced meets the standards, it is necessary to pay attention to key factors such as raw material selection, production process, equipment use, and quality control. Only by striving for excellence in these aspects can we truly produce high-quality water-soluble non-woven products.
