There are various quality issues commonly encountered in slipper production.
It not only affect the performance of the product, but may also pose a potential threat to consumers’ health. Here are some common quality issues in the slipper production:
1.Material issues
Excessive plasticizer:
PVC and other plastic materials commonly used in slipper production may contain plasticizers such as phthalates to increase flexibility. However, these plasticizers are prone to exceeding the standard and are harmful to human health, especially affecting children and pregnant women more significantly. They may enter the human body through skin contact, respiratory or digestive tract, disrupt the endocrine system, and affect reproduction and development.
Excessive heavy metal content, such as lead, is also a common problem in slipper production. These heavy metals are harmful to multiple systems in the human body, especially having a serious impact on the growth and intellectual development of children.
2.Physical performance issues
Insufficient tensile strength of the sole:
This may cause the slippers to deform or break easily during wearing, affecting their service life and safety.
Poor wear resistance of outsole:
Slippers with poor wear resistance will experience rapid wear on the bottom after prolonged use, which not only affects aesthetics but may also reduce slip resistance and increase the risk of falling.
Non slip performance:
The slip resistance of slippers is crucial for preventing falls. If the anti slip performance does not meet the standard, especially on damp or smooth ground, the wearer is prone to slip and get injured.
3.Slipper production process issues
Poor bonding process:
The upper and sole of slippers usually need to be connected through adhesives such as glue. If the bonding process is poor, it may lead to problems such as glue cracking and delamination, affecting the durability and safety of slippers.
Odor issue:
Various chemical materials and additives may be used in the slipper production, and if not handled properly, they may produce irritating odors. These odors not only affect consumers’ user experience, but may also pose a threat to human health.
4.Design issues
Inappropriate size:
The size design of slippers is unreasonable, which may cause discomfort or easy detachment, affecting the effectiveness of use.
Unreasonable style design, such as narrow or wide shoe uppers or thin or thick shoe soles, may affect the comfort and safety of slippers.
5.Other issues
Microbial contamination:
Slippers may be contaminated by microorganisms such as bacteria, mold, etc. during production, storage, and transportation. These microorganisms may pose a threat to human health, especially in humid environments where they are more likely to thrive
Irregular label identification:
The label identification of slippers should be clear and accurate, including product name, material, size, manufacturer and other information. If the label identification is not standardized or missing, it may result in consumers being unable to correctly understand product information, affecting purchasing decisions and usage effectiveness.
The quality issues encountered in the slipper’s production involve materials, physical properties, production processes, design, and multiple other aspects. In order to ensure the quality and safety of slippers, manufacturers should strictly comply with relevant standards and regulations, strengthen quality control and testing efforts, and ensure that products meet relevant requirements.
How to slove slipper’s quality problems:
Xiangxi produce silicone additive and the relative products which can solve many slipper’s quality problem during slipper production:
Anti-abrasion agent: can solve the poor wear resistance.
Dosage: 5%~8%. Few doage and will not affect the cost too much.
Anti-slip agent: can solve the quality problem of non slip performance.
Dosage: 5%~8%. Few doage and will not affect the cost too much.
POE: Can solve the quality problem of Insufficient tensile strength of the sole.
Dosage: 10%~20%
Good quality and competitive price.
