There once was a master of keyboard and gaming equipment in the equipment circle. He kept saying that when buying a soft case, you should buy a smaller one because it will deform after being washed a few times.
Domestic OYO and Guigu Tactical have made replicas of the TAD Henry collar sweater. OYO says that it does not add spandex, so its fabric is better, while Guigu Tactical says that adding spandex is better.
Are these statements correct?
First answer:
1: The soft shell will deform after being washed a few times. There are only two possibilities, either buying a fake spandex elastic soft shell or aging spandex that has been in stock for many years. soft shell.
2: Guigu’s tactics are right.
Spandex is polyurethane fiber. It is called LYCRA in the United States, ELASTANE in Europe, DORLASTAN in Germany, and NEOLIN in Japan. The most famous one and the one with the best quality is LYCRA.
Spandex fabrics are usually woven into fabrics using core-spun yarns and covered yarns. The processing is relatively difficult, and dyeing is even more difficult, especially for fabrics with relatively high spandex content, such as Schoeller. )’s W400 soft shell fabric contains more than 20% spandex, which is very difficult to dye, which is why many spandex products are expensive.
The disadvantage of spandex fabric is that it has poor heat resistance, not that the fabric is easy to age. On the contrary, one of the advantages of spandex is that it is resistant to aging. And spandex can maximize elasticity (high content of spandex), wrinkle-free, and good retention. Soft and smooth to the touch.
The domestic spandex industry is also very developed. Huafeng Spandex, a listed company, is famous for its spandex products.
There are a lot of fake Leica and a lot of fake spandex on the market. Some knock-off stretch fabric products are easily deformed, or the elastic rings on the cuffs, necklines, and hems of some clothes are easily deformed. This It is caused by some other elastic fabrics used.
For example, common elastic yarn, also called rubber yarn, its scientific name is vulcanized polyisoprene, which is the earliest elastic fiber material. Its main application products are socks using thick yarn. The elasticity retention is relatively poor.
There are also several elastic fabrics, such as the most famous T400 fabric in China, which uses DuPont’s SORONA as the main raw material and is different from ordinary PET. The scientific name of composite elastic fiber made through composite spinning process is CONTEX.
This kind of fabric has a small elastic range, but its elasticity retention is relatively good. At the same time, the drape of the fabric is very good. The clothes made are comfortable and have a strong surface texture.
There is also DOWXLA elastic fiber fabric made by Dow Ski in the United States, which has higher heat resistance than spandex. There is also Teijin’s polyether elastic fiber fabric from Japan, which has strong acid and alkali resistance. There is also a rare hard elastic fiber fabric that is resistant to low temperatures and will not become brittle in low temperature environments, but still has good elasticity.
However, these elastic fabrics are not as mature and stable as spandex elastic fabrics. The production and processing of spandex fabrics, from bleaching and dyeing, to the final finished fabrics, and the processing and production of ready-made garments (garment processing factories make spandex elastic fabrics) There are many opportunities, and the process operation process is easy to stabilize). The entire process is a very mature technology, so it has strong stability.
