Reasons why Melt-blown fabric becomes brittle after production

Reasons why Melt-blown fabric becomes brittle after production

(Summary description)1. If the aspect ratio of the spinneret of Melt-blown fabric is small, the holes are thick and short. After the polymer is sprayed, the fibers are thicker, the gaps are larger, and the water absorption is stronger for a long time , so the Melt-blown fabric is neither soft nor brittle.

Information

1. If the aspect ratio of the spinneret of Melt-blown fabric is small, the holes are thick and short. After the polymer is sprayed, the fibers are thicker, the gaps are larger, and the water absorption is stronger for a long time , so the Melt-blown fabric is neither soft nor brittle.

The processing method of Melt-blown fabric requires that the molecular weight distribution of the melt-blown material be as narrow and uniform as possible. A high-temperature gel chromatography for testing the molecular weight distribution of Melt-blown fabric, the test temperature range is from 30°C to 220°C, and it has the function of automatic sample injection to reduce the influence of human factors.

This high-temperature gel chromatography for testing the molecular weight distribution of Melt-blown fabric is equipped with three detectors of the time difference, viscosity, and light scattering, which solves the problem of molecular weight and molecular weight distribution testing of most polymers at this stage.

2. The winding device of Melt-blown fabric is too short, there is residual heat in the winding process, and it cannot be cooled quickly. After a few days, the PP material becomes brittle after crystallization (some people add a crystallization nucleating agent as a softener).

3. Packaging. If the Melt-blown fabric absorbs too much water, it can easily become brittle. Generally, Melt-blown fabric will be wrapped with stretch film and sealed.

Through the above introduction and analysis of the causes of brittleness after producing Melt-blown fabric, hope it helps you.

The manufacturing process of oil absorbent pads  

Oil absorbent pads are a class of fibers and non-woven fabrics made of inert polypropylene melt-blown that have been specially treated to precisely absorb and retain liquids. The absorbent products of oil absorbent pads are all wrapped in polypropylene fibers or non-woven fabrics sewn with surface-active treatment agents.

Introduction

Introduction of classification of oil absorbent pads

Oil-absorbing cotton products are usually in the form of oil absorbent pads (oil-absorbing sheets), oil-absorbing strips, oil-absorbing rolls, oil-absorbing pillows, and oil-absorbing fences. Oil absorbent pads, such as oil absorbent pads, are suitable for leakage treatment in a small area.

Features

Features of Melt-blown fabric

Melt-blown fabric filter material is randomly distributed and bonded together by polypropylene microfibers. The appearance is white, flat, and soft. The material fiber fineness is 0.5-1.0μm. The random distribution of the fibers of the Melt-blown fabric provides more opportunities for thermal bonding between the fibers.
