1. The biggest difference between semi-worsted and traditional woolen worsted and roving process lies in that it integrates cotton spinning technology with woolen spinning technology, forming a new multi-component mixing process. The last channel is worsted winding, wire, double twist equipment. The change of equipment and technology solved the problem that the original woolen spinning equipment could not solve.

Semi-worsted spinning can realize the successful blending of natural raw materials such as cotton, wool, silk and flax with other new man-made fibers and chemical fibers. The raw materials of woolen semi-worsted spinning include the successful blending of natural fibers such as cashmere, wool, spun silk, rabbit hair, cotton and ramie, artificial fibers such as soybean protein fiber, milk protein fiber, tencel, Modal, bamboo fiber, viscose fiber and chemical fibers such as acrylic fiber, dacron and polyamide fiber, and the product structure is extremely rich.

Woolen spinning is a kind of spinning method

Spinning cashmere is a kind of coarse number, and the price is low, wool yarn nature is relatively poor, easy to pilling, deformation. The number of semi-worsted is about 28/2, and compared with coarse spinning, the price is higher and the quality is better. Worsted cashmere is the best, accounting for more than 2/48, making soft and delicate articles. Very comfortable and warm. But this kind of yarn price is very expensive, commonly known as "soft gold in wool yarn". About more than 1800 yuan /kg.

There are two kinds of high-count cashmere yarn production line, semi-worsted yarn and fully worsted yarn. Semi-worsted yarn can be spun below 16.67tex without combing to remove short fibers, which can meet the needs of general light and light fabrics, and has a high yarn rate and relatively low cost. The number of spun yarn can reach 10tex after combing to remove the short fiber, but the cost is high, and due to the strength of the yarn, it often needs to be blended with other fibers, which is suitable for special light and light fabrics. Therefore, the development and production of semi-worsted cashmere yarn are paid more and more attention to by the cashmere yarn market at home and abroad.

2、the difference between woolen and worsted wool

Identification of woollen materials:

(1) Sensory recognition. All pure wool products generally have rich and smooth suede, uniform color and luster, warm touch, no crease after folding, soft wool body and strong resilience.

(2) Combustion identification. Smoking single yarn with fire, smoke slowly, smell the smell of burning hair, gray black crisp block.

(3) Identification of product number. Every piece of wool sold has a label with a five-digit article number on the label. If the first digit is 0 word is pure wool, the first digit is 1 word, is blended products. For example: 01001 -- pure wool Malden; 11001 -- Blended Malden; 71001 -- Pure chemical fiber Melden.

Identification of worsted wool: worsted wool is a high-grade clothing fabric made of pure sheep wool, which can also be mixed with a certain proportion of wool-type chemical fibers or other natural fibers. It is processed by combing equipment, combing, combining, drafting, spinning, weaving, dyeing and finishing for many times. It has the good elasticity, softness, unique fleece resistance and wrinkle resistance of animal hair, and also has warmth protection after absorbing moisture or sweat.

Difference between woolen and worsted:

Worsted fabric has smooth surface and clear weave. The luster is soft and natural, and the color is pure. Soft and elastic to the touch. Pinch with the hand to loosen the surface, crease is not obvious, and can quickly restore to original state. Most yarn count is double ply.

Woollen cloth is plump and dense in texture. The surface has a fine nap, weave generally do not show. The feel is warm, plump and elastic. Most of the yarn is a single thick yarn.
