The weather forecast of Nandu shows that there will be rain in Guangzhou in the next few days. Elderly people, especially arthritis, should pay more attention to keeping warm and humidifying and cold. Put on the knee guard if necessary to prevent the knee from being cold.
Limos and knee pads, as products that protect the waist and knees of the human body, have the functions of sports protection, cold prevention and insulation, and joint maintenance. Most suitable for middle -aged and elderly people, athletes, waist or knee patients. However, there are many types of middle -aged and elderly knee padding and waist protection, and the prices are diverse. From tens to thousands of yuan, and the propaganda functions are different, which waist and knee padding products are worth planting?
On February 21, the Beijing Consumer Association released the “Comparison Test Results of Middle -aged and Elderly Bulfin Knee”. The results show that brands such as “rehabilitation home” and “Zhou Lin spectrum” are unqualified.
“House of Rehabilitation”, “Zhou Lin spectrum” and other brands
Wetness and heat -absorbing heat
It is reported that the performance of hygroscopic and heat refers to the thermal fiber of the sample to capture water molecules with higher kinetic energy in the air and convert its kinetic energy into thermal energy to achieve the performance of the fever.
In the test of hygroscopic heat and heat, the standard value is the maximum temperature increase ≥4.0, and the average temperature increase in 30 minutes ≥3.0. The actual measurement value shows that the maximum temperature increase of the spontaneous heating waist care of the “rehabilitation house” is only 1.7, and the average temperature in the 30IN increases the value of 1.1; the average temperature of the “Zhou Lin Spectrum” knitted knee pad 30 minutes is only 2.4.
Wetness and heat -resistant performance test results map
“Antarctic” wool protective gear
Elasticity is the worst
The horizontal stretch elastic response rate refers to the stretching and recovery performance of the waist care and knee pads. Whether there is a significant decrease in elasticity after a long period of use, which affects the effect of use. Horizontal stretching elastic response rate is the indicator of consumers more concerned.
The overall results of the test sample were good, of which the test results of the two groups were less than 85%, namely the “Antarctic” woolen waist, wool protective gear (measured value of 77.3%), “Leawell Lingyuan” far -infrared warm protection gear, far infrared warmth Limble (83.1 % measured value). According to reports, the larger the value, the better the stretching and recovery elasticity, and the better the elasticity can be maintained after a period of time.
“Kangshu” bionic crustal knees
The worst breathability
Performance is also a performance that consumers pay more attention to and can intuitively perceive. When the breathability index is not less than 180mm/s, the sample is more comfortable to wear. The greater the air permeability, the better the breathable effect.
A total of 40 groups of samples were tested this time. The permeability measured values are within 10mm/s: “Kangshu” bionic crustal knees, “yongquan Yongquan” belt, “Luy λo Lu Yao” protective gear (actually knee pads), “Kadun Katton” protective gear (real For knee pads). Among them, the “Kangshu” bionic crustal knee -knee, the worst breathability, the measured value is only 3.294.
Six products such as Huiyi and Youzhu
Network propaganda brands do not match the real thing
Among the 37 groups of online testing samples, there are six groups of sample webpages on the text that explicitly shows the brand, which is not only different from the brand on the online promotional pictures, but also inconsistent with the real brand.
These six groups of samples are: Hhayi (online picture and physical brand Yongquan Yongquan), Youzhu (online picture and physical brand Kadun Carton), Wanshitai (online pictures and physical brands Kangshu), Yuer Lian (online picture and real brand Luyao Lu Yao), of which Wondoo (physical brand Kadun Carton) and WONDOO (Lara Star) of WONDOO Doubt about the content of the brand.
There are design processes such as digging or network eyes
Actually, it can strengthen the sweating effect
How do consumers buy waist and knee padding products? The Beijing Consumer Association issued consumer reminders.
01
Look at the propaganda:
When buying products, consumers should try to choose products with complete content, especially product names, factory names, and address. Product logos are not complete, irregular, and inaccurate, you should buy it carefully.
When choosing a certain functional product, in addition to listening to the introduction of the sales staff, it also depends on the labeling content of the product itself. If orally, there is a function that has not been clearly marked by the product, you need to identify it carefully.
In addition, in cold weather, if consumers have strong demand for heating or warmth, in addition to buying products with corresponding functions, other auxiliary methods can be added to achieve better heating or warmth effects.
02
Look at the whole
Taking this comparison test as an example, although the results of some samples are not the best, there are design processes such as digging or mesh eyes, which can actually strengthen the sweat effect. When buying, consumers must not only consider the characteristics of the product fabric itself, but also the effect of the overall dressing.
03
Try
Taking this comparison test as an example, “the thicker the more more cover the more” and “the thinner the more breathable” are the common concepts in daily life. In addition to thin thickness, the components of the fabric tissue structure and the fiber used may affect the breathability of the sample. Essence When buying actual purchase, consumers can use their mouths to blow them close to the fabric. It is easy to blow through, and the breathability is better. On the contrary, the breathability is poor.
04
Comparison
When choosing online products, pay attention to whether the real objects received and online propaganda are different. Some products purchased by some offline channels are also sold on the Internet, and consumers can compare their choices.
05
Evidence
When buying waist protection and knee pad products, consumers should ask for and retain shopping vouchers so that quality problems can effectively protect their legitimate rights and interests.
