The development history of polyester fiber can be traced back to 60 years ago, and the initial symbol of the times is Raschel;
The fabric was upgraded around 1998, and the symbol of the times was "polar fleece";
In 2002, it was upgraded again, and the symbol of the times was "coral velvet";
The upgrade logo around 2006 is "flannel";
The upgrade logo around 2008 is "Fu Guirong"
The ultimate upgrade sign around 20 13 is "warm cotton wool" integrated with antistatic fiber yarn and other technologies, and wool has also been improved in many versions. In fact, the symbol naming of each era has certain significance and is also the presentation of creativity.
Gram weight is generally divided into 380; 300; 230.
380 grams is generally suitable for thickening blankets.
300 grams, for the mainstream supply. Mainly to make clothes and blankets.
230 grams, generally single-sided velvet, mainly used for home textile kits.
There are also 120 grams, but they rarely appear in the mainstream market (the wool is too fine, and the appearance and feel are not good).
You get what you pay for, and the price is based on quality. Although the weight of fabric is related to the price, it is not the main reason for leading the price. Mainly depends on whose yarn (base material) is used.
At present, no matter what kind of cashmere is on the market, it is only a branch symbol to distinguish the origin of the product, and it stays in the lexical evolution of the "flannel" era; That's all. Only "warm cotton wool" has passed the upgrade of two versions, and this kind of fabric with strong permeability will not be popularized in the whole market in a short time, which is even more difficult to compare.
Shop around and need arguments to compare! Your question is a bit general. I'll give you the following common sense for your reference:
In fact, thickness and weight are not the main reasons for keeping warm or PK price, but the properties of materials play a vital role. Another explanation is the symbol of the flannel era, which is precisely the warm but "not constant temperature" attribute material.
