At present, there are several differentiation methods for microfiber wiping cloths on the market:
A. Divide according to the thickness of the original silk. Of course, the finer the original silk, the more delicate the fabric woven, and the less damage to the lenses and frames. At present, most mainstream products in the market are woven using 75d silk. Some manufacturers also use 95d or even 150d raw silk to improve texture and reduce prices.
B. According to the composition of the raw silk.
1. 100% polyester.
2. 80% polyester and 20% nylon.
3. 70% polyester and 30% nylon.
4. 30% polyester and 70% nylon.
Due to the superior properties of nylon compared to polyester (nylon fibers have better flexibility, elastic recovery rate, wear resistance, alkali resistance, moisture absorption, and lightness compared to polyester fibers, but their cost is about twice that of polyester fibers), fabrics with higher nylon content have better performance and quality, and relatively higher prices.
At present, the production of mirror fabrics in China is mainly based on the first two types. Our company’s “Versatile” brand mirror fabric imported from abroad is mostly the fourth type (30% polyester and 70% nylon)
C. Distinguish according to processing technology.
1. Grinding. For example: Nite-8 matte series, Nite-5 series, and Siyiduo (imported) series
2. No sanding. For example: Knight, Knight-1 (imported)
Brushed mirror cloth has a softer and thicker texture compared to non brushed ones. But there was no significant improvement in the wiping effect. The wiping effect is mainly distinguished based on the composition.
In addition, currently there is a large portion in the industry that is distinguished by needle one (for example, all products of our company except for the nite-8 series), needle two (nite-8 series), and needle three.
Generally speaking, needle one is better than needle two, and needle two is better than needle three.
D. Specifically, when it comes to how to choose eyeglass fabrics, in general, while wearing glasses, the store will choose different quality eyeglass fabrics as gifts to customers based on the price and grade of the lenses and frames they are equipped with.
If an individual directly purchases mirror cloth, the most direct choice for reference is to comprehensively refer to the composition and craftsmanship of the mirror cloth. Special attention should be paid to the moisture absorption, wear resistance, alkali resistance, and elastic recovery rate of the mirror cloth as a reference.
If there is a professional instrument, then it needs to be tested from various aspects such as color fastness, wear resistance, alkali resistance, weight, water absorption, elasticity, composition, etc., which will not be further discussed here.
The key is how to choose without professional equipment.
In the absence of professional instruments, it can be summarized as one look, two strokes, three suction, and four wiping.
First, appearance: it is not only to check whether the color of the mirror fabric is correct, but also whether the luster is flat (if the dyeing is not good, the color is biased, and the luster is either dark or too bright, which is the so-called color thief)
Second,stretching: means holding both sides of the mirror cloth with both hands and then stretching in the opposite direction. This article examines the elasticity and resilience of the mirror fabric. It is better to recover quickly and completely after letting go.
Third, absorption: means you can drop some water onto the tabletop, and then touch one corner of the mirror cloth slightly against the water droplet. This mainly depends on the water absorption of the mirror cloth. Distinguish between good and bad based on the speed and amount of water absorption.
Four wipes refer to the actual wiping of the lens, which is tested by wiping it once. The cleaner the wipe, the better.
