How to Make Non-slip Slippers? Scientific Design of Sole Pattern and Material

As one of the most common home and outdoor shoes in everyday use, slippers are valued by customers for comfort and convenience. Anti-slip performance is often overlooked, however, which is a significant factor affecting the safety and experience of their use. Especially in damp, slippery ground, slippers with the anti-skidding framework are not supplied, which may lead to slips and falls and other unsafe conditions. Therefore, in designing and manufacturing non-slip slippers, the scientific choice of sole design and material plays an important role.

Why is The Non-slip Performance of Slippers so Important?

Anti-slip performance is directly related to the safety of the wearer. In the kitchen, bathroom, swimming pool and other environments with frequent water stains, the slightest attention may slip, especially the elderly and children are more likely to fall into accidents. Excellent non-slip slippers not only prevent accidents but also improve wearing comfort and stability and enhance product competitiveness.

Sole Pattern Design: Both Function and Science Are Emphasized.

Diversity of Pattern Shapes

Scientific research and market evidence show that the geometric shape of the sole pattern directly affects the strength of friction. Common non-slip slippers patterns include:

• Wave pattern: It can quickly divert water, reduce the water film between the sole and the ground, and improve the grip in wet and dry areas.
• Diamond pattern/cross pattern: multi-directional friction design, suitable for a variety of walking positions and angles.
• Dot/granule pattern: enhances localized friction, commonly used in EVA foam slippers.
• Horizontal stripe: horizontal bite, suitable for smooth floors, more stable wearing.

The scientific design of grain combination should not only consider the aesthetics, but also optimize based on mechanical analysis and usage scenarios.

Stripe Depth and Spacing

The greater the depth of the grain, the stronger the drainage of the sole on the water surface, but too deep may affect the comfort; while the spacing affects the anti-slip and easy to clean performance. Reasonable control of the spacing of the grain helps to ensure friction while reducing the accumulation of soil, to enhance the service life and cleaning convenience.

The Choice of Non-slip Slippers Materials: PVC and EVA Performance Comparison

Non-slip slippers’ performance not only relies on pattern design, the material is equally important. Currently, the two most commonly used materials in the manufacture of slippers are PVC and EVA.

1. PVC material

• Advantage: high hardness, strong abrasion resistance, high friction, suitable for outdoor slippers or work scenes.
• Disadvantage: relatively heavy, less elastic, long-term wearing may affect the comfort.

2. EVA material

• Advantage: light and soft, good elasticity and shock absorption, suitable for home and leisure scenes.
• Disadvantage: If the density is not properly designed, it is easy to slip, and needs to be matched with a professional anti-slip pattern design.

In order to achieve both lightweight and non-slip goals, many manufacturers will use composite materials or add rubber particles to further enhance the friction.

The Process of Upgrading: Injection Molding vs The Splicing Process

The injection molding slipper process can be more accurately controlled to ensure the stability of the contact between the sole and the upper, at the same time, through the mold refinement design, so that the sole texture and material fusion is higher, to enhance the overall anti-slip performance. The splicing process, although lower cost, but stability and consistency are slightly inferior.

Summarize: The Three Key Points of Scientific Anti-Slip Design

• Texture design should be combined with mechanical and measured data to meet the needs of different floors and people.
• Material selection should take into account the friction and wearing comfort, combined with the use of the scene.
• The production process should ensure the accuracy of the pattern and the integrity of the sole, so as to improve the non-slip slippers’ effect and durability.
