Where is thehydrophilic masterbatch most suitable to be used? Match the scenarios accordingly. 

hydrophilic masterbatch is widely used in non-woven fabrics (such as medical supplies and hygiene products), agricultural mulching fabrics, filtration materials, etc. Its main function is to impart permanent hydrophilic properties to polyolefin fibers like polypropylene (PP), enabling functions such as drainage, filtration, or anti-static. Different end products have varying requirements for hydrophilic effects. Below, we will help you match them according to common application scenarios. 

Scene 1: Eisai and medical non-woven fabrics (diapers, sanitary napkin linings, medical sheets) 

These products require the liquid to penetrate quickly and with low back-suction, while ensuring that it is gentle and non-irritating to the skin. 

Recommendation focus: Select highly efficient hydrophilic masterbatches, with the requirement that the liquid penetration time be short (e.g. ≤ 3 seconds), and the back infiltration amount after multiple penetrations be low. The hydrophilic agent should be evenly distributed on the fiber surface to ensure rapid drainage on the surface layer. Lu'an Qingsong Pigment Masterbatch Co., Ltd. specializes in the production of non-woven fabric pigment masterbatches and hydrophilic masterbatches, and can match the hydrophilic agent system according to the application. 

Safety requirements: The hydrophilic masterbatch used by Eisai must comply with relevant biocompatibility standards and must not cause irritation or sensitization to the skin. During procurement, the supplier can be requested to provide a report on skin irritation tests. 

Scene Two: Agricultural Covering Fabric 

The agricultural application requires the non-woven fabric to have the functions of water permeability and moisture retention, enabling rainwater or irrigation water to quickly penetrate into the soil, while also having certain weather resistance. 

Recommendation focus: Select masterbatches that possess both hydrophilic and anti-aging properties to ensure that the hydrophilic effect remains stable in outdoor environments. The hydrophilic effect should be moderate - capable of allowing rapid water penetration while not causing excessive water evaporation. 

Durability requirements: The agricultural covering fabric needs to maintain its hydrophilic property throughout the entire planting season (typically 3-6 months). When purchasing, you can inquire with the supplier whether they have conducted tests on the hydrophilic effect after aging. 

Scene Three: Filtering Materials 

The filter material requires the hydrophilic masterbatch to provide a uniform wetting effect to prevent the filtration efficiency from decreasing due to local hydrophobicity. 

Recommendation focus: Select a masterbatch with evenly distributed hydrophilic agents to ensure that the entire filtration area can be uniformly wetted by the liquid. The hydrophilic effect does not need to be pursued for "the fastest" but rather for "the most uniform". 

Durability requirements: When used for industrial filtration, it may be necessary to maintain hydrophilic properties even after the liquid is soaked for a long time. During procurement, it is advisable to inquire whether the supplier has test data on the hydrophilic effect after water washing or long-term soaking. 

Summary and Selection Suggestions 

When purchasing hydrophilic masterbatch, it is recommended to follow the following steps for confirmation: 

Pre-determined application: for medical use, agricultural use, or filtration? Different scenarios place different emphasis on penetration speed, uniformity, and durability. 

Clarify performance targets: Inform the supplier of the target liquid penetration time, back-suction volume requirements, and whether anti-aging or water-wash resistance functions are needed. 

Sample machine testing: Conduct a small-scale trial on your non-woven fabric production line to test the hydrophilic effect and spinning stability of the finished products. Once the results meet expectations, then proceed with the expansion of the order.
