it's all pure cotton. What's the difference between 50 and 5,000?
n strict grades, three lines can be classified according to the cultivation of cotton and the length and thickness of fiber:
Coarse lint (rejected cotton) - also known as Asian cotton, refers to a variety of cotton, cotton and grass cotton, short fiber, and elastic. This kind of cotton fiber because length is short, fiber rough hard, color is white or stay white, little mercerization, use value and unit output are low, again home already basic eliminated, the world also does not have the product cotton production.
Fine lint (the most common type of cotton) - also known as land cotton, is a variety of cotton fiber fineness and length of medium, white or creamy white, mercerized, can prevent 11~100tex (60~6 British) yarn. Fine cotton accounts for 85% of the world's total cotton production and is the most important cultivated cotton species in China at present.
Long staple cotton (also known as sea island cotton) -- also known as sea island cotton, is a variety of island cotton and sea hybrid cotton, fiber long, fine and soft, white or light yellow color, rich in mercerization, good quality, is produced under 10tex cotton yarn raw materials. The main producing countries are Egypt, Sudan, the United States, Morocco, central Asian countries. China's main production base of long-staple cotton in xinjiang and other parts of the region. Long - staple cotton can be divided into special long - staple cotton and long - staple cotton.
The flowers have to be spun into yarn before they can be woven.
Often say combing cotton is to use comber yarn to weave. No matter what kind of cotton, combing is better than normal, combing is the precondition of good fabric.
In addition, yarn thickness and fabric density are two important indicators of fabric quality, which is often referred to as "yarn count density".
Key on the blackboard
Yarn count refers to the degree of yarn thickness, the higher, the finer yarn, the higher the raw material requirements.
The British count (Ne/S) refers to the multiple of 840 yards per pound of yarn at a common moisture regain. The higher the count, the finer the yarn. The imperial count is not the legal yarn fineness index, but it is still widely used in enterprises, especially in the cotton textile industry.
Ne -- the number of yarns in English, in English;
Le -- length of yarn, yard, 1 yard =0.9144m
Gek -- the weight of the yarn, pounds, 1 pound =453.6 grams
K -- coefficient (different yarn lines, different values, cotton K=840, combed wool K=560, rough wool K=256, flax yarn K=300
The higher the yarn quality, the better. It is generally believed that the 60S is a high-class fabric, the high-grade bedding is useful to the 80S, 100S and higher, and 200S is generally used in high-end clothing fabric
Fabric density refers to the number of roots of yarn in warp or weft per unit length of fabric, expressed in M, in root /10cm.
Warp density, also known as warp density, is the number of warp roots per unit length along the latitude in a fabric. The filling density, also known as filling density, is the number of filling roots in the fabric along the warp unit length.
It is customary to write the warp and weft density as MT x MW from the right side. For example, 236 x 220 means that the fabric is 236 /10cm and the weft density is 220 /10cm.
In the industry, the sum of the number of warp and weft roots is often described with unit T. For example, if there are 133 warp threads and 72 weft threads, the fabric density is about 200T(root).
