What are the types of the premium cotton?<\/h2>\n\n\n\n

The ordinary cotton in the market has a fiber length of 15-35mm, and it accounts for 90% of the global cotton production. However, the premium cotton has a fiber length of over 33mm with natural silky luster, usually called extra-long cotton(ELS cotton), it is well recognized high-quality cotton. And depend on where they are grown, it marketed under distinct commercial names including Pima Cotton, Giza Cotton, Sea island Cotton etc.<\/p>\n\n\n\n

Pima Cotton<\/h2>\n\n\n\n

Pima Cotton is mainly from the US and Peru, the top grade of American Pima is branded Supima\u00ae, certified by the American Supima Association. Its fibers average 38mm in length, making it twice as strong as normal cotton. And the fiber are much finer, can make the denim fabric is smoother and highly resistant to pilling.<\/p>\n\n\n\n

\"Colorful

Sea Island Cotton<\/h2>\n\n\n\n

Authentic Sea Island cotton is exclusively harvested in the West Indies, mainly across Caribbean Island. But the annual output only 4 parts per million or less. Its fiber length can be over 50mm, the longest fibre in the world, it reflects light 50% better and ordinary cotton which make fabric has silky sheen look. And it has the highest natural twist strength, resulting excellent resilience and superior tensile strength. And because of its high resilience, and when it weave to fabric,fabric will has better bounce-back. Even after many washing, it can stays good looking.<\/p>\n\n\n\n

However, the authentic must certificated by the WISICA and each kilo of the cotton has it is unique number. So most “Sea Island Cotton” on the market is from India, Egypt or Peru.<\/p>\n\n\n\n

Giza cotton is the commercial name for Egyptian Long-staple Cotton. It primarily consist of varieties like Giza 45, Giza 70 and Giza 86.And the Giza 45 is best performance in the staple length and physical metrics but output is very limited.
