The trademark of wool is a small label attached to the yarn branch, usually with a 3-digit number printed on it. The first digit represents the raw material of wool, and there are 10 kinds from 0 to 9; the last two digits represent the count of single yarn. The larger the two digits, the finer the yarn, and the number of turns in each small skein is The more, the less material is used to weave clothes. If you add a "4" in front of the three-digit number, it means it is a trial product (it also means a new product). []2$rJZD9

1) All wool yarn: the first digit of the item number is 1 or 2. The first digit 1 indicates that the yarn is spun from heterogeneous wool. Heterogeneous wool refers to a piece of wool that has different thicknesses from top to bottom, and has thicker and rougher hairs. The graded wool in domestic wool is all heterogeneous wool. Wool grades are different, and the content of coarse cavity hair is also more or less. For example, item numbers 168 and 170 wool are made of domestic third- and fourth-grade wool. There are many coarse-chambered wools poking out on the surface, which makes it rough to the touch and tends to become stiff when woven into clothes. When selecting this type of yarn, choose coarse-chambered wool and It is better to have fewer yarn defects. RpmBP[ dgt; There is less coarse cavity hair, the hand feels soft and elastic, and the appearance is smooth, but the color is not bright enough and the price is relatively high. 1Rb There are certain standards for wool fineness and length of homogeneous wool. The first digit of the product number of this kind of yarn is 2. For example, 268, 272, 275, 219, etc. $p}~, Kp/

2) Blended wool: Wool blended with wool-type acrylic and heterogeneous wool. The first digit of the product number is 7, which is the same as heterogeneous wool. Compared with wool yarn, it improves the strength and service life of wool yarn, improves color and reduces pilling. The first digit of the product number is 4 for wool blended with homogeneous wool and heterogeneous wool. The first number 6 represents the blend of homogeneous wool and acrylic fiber. t=E|RYC(k

Single yarn joints are allowed in production, but they cannot exceed the specified standards, that is, one joint is allowed for a small skein (50kg); three joints are allowed for a large yarn (250kg). If this standard is exceeded, the yarn will be downgraded. /qqamp;'}TZP

The "mohair" on the market is not real mohair, but polyacrylonitrile fiber (trade name acrylic fiber) among chemical fibers. It is a polymer compound made of acrylonitrile monomer, which is not easy to age and has excellent thermal insulation properties. After rough combing and spinning, it can be spun into yarn with a hairy surface and disordered fiber arrangement. Modification. A special acrylic dye is used during dyeing. The dye diffuses into the fiber and chelates with the metal atoms in the fiber. Therefore, the dyeing performance of the acrylic fiber is judged from the light fastness of the fiber. Even better than pure wool, but its overall performance is still inferior to pure wool. Acrylic fiber is commonly known as "artificial wool".
