How to choose glasses cloth
There are some methods to distinguish microfiber cleaning cloths in market.
Yarn thickness: it is certain that thinner the yarn, finer the cloth, and less damaging to the lens and frames. At present mainstream
products are almost made with 75D yarn. Some manufacturers adopt 95D or even 150D yarn to improve hand feeling and reduce cost.
Yarn component
100% polyester
80% polyester & 20% nylon
70% polyester & 30% nylon
30% polyester & 70% nylon
Compared with polyester, nylon has better flexibility, elasticity, abrasion performance, alkali resistance, moisture absorption and light weight,
but its cost is twice as that of the polyester. Therefore, the cloth with more nylon has better performance, and the price is accordingly higher.
At present domestic cloths basically belong to the type1 & 2, and “Finestar” cloths we imported are almost type 4 (30% polyester & 70% nylon)
Processing technology
Brushed. For example: knit-8 brushed collection, knit-5 and suede collection (imported)
Non-brushed. For example: knit and knit-1(imported)
Compared with non-brushed cloth, brushed cloth is softer and thicker, but it has no obvious improvement on cleaning result which mainly depends
on components.
Besides, currently the cloths are also divided into knitting-1 (all of our products except knit-8 collection), knitting-2 (knit-8 collection)
and kniiting-3 in the industry.
Generally speaking, knitting-1 cloth is better than knitting-2 that is better than knitting-3 cloth.
Generally, shop shall choose different quality cleaning cloth for customers as gift based on lens and frame prices when matching glasses.
If buying cloth directly, one shall consider cloth component and process technology, as well as moisture absorption, abrasion resistance,
alkali resistance and elasticity.
If professional instrument is available, one shall consider color fastness, abrasion resistance, alkali resistance, weight, water absorption,
elasticity and component.
The key is how to choose cleaning cloth without professional equipment.
It can be summarized as looking, stretching, absorbing and scrubbing.
Looking: It refers to look if it has right color with gentle luster (With bad dyeing, the color shall be off and the luster is either too
dark or too shiny)
Stretching: It refers to hold two sides of the cloth and stretch it toward two negative directions. This is to check cloth’s elasticity.
The cloth is good with fast and complete restoration after being loosen.
Absorbing: put some water on the table, and then make one corner of the cloth touch the water drops. This is to check cloth’s
water absorption. It is distinguished by absorption speed and absorption capacity
Scrubbing: It is to scrub lens one time to test. The cleaner, the better.
