The key factors for material selection in the sanitary cotton sliver production line mainly include the following aspects:
1. Hygiene requirements: Sanitary tampons are products used during the physiological period of women, so the hygiene requirements for materials are very high. The material selection must comply with relevant hygiene standards, such as the use of medical grade materials with good permeability and absorption performance to ensure product safety and hygiene.
2. Breathability: The material of sanitary tampons needs to have good breathability to provide better breathing space for the skin, reduce moisture and bacterial growth, and improve user comfort. When selecting materials, it is necessary to consider the softness of fibers and the size of fiber gaps to ensure appropriate breathability.
3. Absorption performance: The main function of sanitary tampons is to absorb secretions, so when selecting materials, it is necessary to consider the material's water absorption and liquid absorption speed, as well as whether it can maintain a dry surface. The commonly used materials include cotton, bamboo fibers, ultrafine fibers, etc. These materials can effectively absorb and fix secretions, avoiding side leaks and odors.
4. Safety: Sanitary tampons are products that come into direct contact with sensitive parts of women, so the safety requirements for materials are also very high. Materials that are non irritating, non allergenic, and non-toxic must be selected to avoid harm to the health of users.
5. Strength and stability: Sanitary tampons are disposable products, so the strength and stability of the material are also very important factors. The material must have sufficient strength to withstand the pulling and pressure of users during normal use, and be not easily deformed or broken, to ensure safety and stability during use.
6. Production cost: The selection of materials also needs to consider the factors of production cost, in order to select relatively economical and reasonable materials while meeting the requirements. The prices and processing techniques of different materials can have a significant impact on production costs, and reasonable choices need to be made based on product positioning and market demand.
7. Environmental friendliness: The selection of materials also needs to consider environmental factors. In the current context of promoting sustainable development, selecting materials with lower energy consumption and low-carbon emissions to reduce negative environmental impacts is one of the important factors that need to be considered in material selection.
The above are the key factors for selecting materials for the sanitary cotton sliver production line. By selecting reasonable materials, the quality and safety of sanitary cotton products can be ensured, user experience can be improved, and production cost control and environmental protection goals can be achieved.
