Wool sweaters originally referred to knitted sweaters made from wool knitting yarn or single-strand wool yarn.

Wool sweaters have become these wool sweaters. A general term for knitwear-like products.

Wool sweaters are made of wool and have a soft feel, good elasticity and comfortable wear.

Cashmere sweaters are internationally known as "cashmere sweaters". Since cashmere is light, warm, soft and slippery, the woven cashmere sweaters are lighter than wool sweaters and are soft and smooth to wear. It is a kind of valuable clothing both at home and abroad, but cashmere is relatively delicate and has poor wear resistance. Therefore, it is generally woven with a blended yarn of 15% nylon and 85% cashmere. Its wear resistance is higher than that of pure cashmere sweaters. About double.

Rabbit woolen sweaters are woven from rabbit fur and wool. Rabbit woolen sweaters have long fur on the surface, and have a special luster and smooth feel. However, because rabbit fur is relatively fluffy and has poor cohesion between fibers, 10% Jinlun and 30% Jinlun are generally used. % or 40% rabbit fur and 60% or 50% wool blend. This blended rabbit wool sweater has a soft luster, a smooth feel, and good warmth retention properties, taking advantage of the characteristics of rabbit fur and wool.

There is also a kind of camel hair sweater on the market. The camel hair used is the down that grows on camels. This kind of fiber has high strength, is soft and shiny, but the fiber is relatively fine and short. The so-called "camel hair sweater" is generally made of a blend of 50% wool and 50% camel hair. Camel hair sweaters have particularly good thermal insulation properties, are durable, and are not prone to pilling. Since camel hair has natural pigments that are difficult to bleach away, it can only be dyed in its original color or in dark colors.

The mohair used in mohair sweaters is also called Angora goat hair. This kind of wool fiber is thick and long, has good elasticity, high strength, white color and special luster, and can be dyed into various bright colors. However, because the fibers are thick, long, less curled, and the cohesion between fibers is poor, it is generally better to produce brushed varieties, which can make the surface of the fabric appear rich and hairy. The long down is not only warm, but also highly decorative.

Identification of woolen sweaters:

First look at the trademark. Woolen sweaters produced by regular manufacturers have product raw materials and content marks on the trademark. If you touch it with your hands, you will find that the real wool sweater is soft, elastic, warm to the touch, and has good warmth retention; the fake sweater feels rough and hard, has poor elasticity, and has no warmth to the touch. You can also use the combustion method to identify it. Use a match to ignite the extracted fibers. When burning, there will be a smell of burning feathers and hair. If the ashes are pressed, it will be pure wool. There is no smell of burning feathers or hair when burning, and the ashes are agglomerated and not easily crushed because of chemical fibers. You can also do a friction test. Wear a wool sweater on a pure cotton shirt for a few minutes, and then take it off quickly. If there is no "pop" sound, it is a real wool sweater; if there is a "pop" sound, or even with static sparks, it is a real wool sweater. Fake cardigan.

For arbitration inspection of wool sweaters, the chemical dissolution method introduced in the first section of this chapter can be used. According to the International Wool Bureau (IWS) standard, pure new wool is >95%; domestic standards require pure new wool >93%, and it can be judged as a pure woolen sweater.

The International Wool Bureau (IWS) is one of the international standardization organizations and was established in 1937. The wool fabric standards established are recognized around the world. The "Pure Wool Mark" promulgated in 1960 has been adopted by more and more countries in the world. Every sweater bearing the "Pure Wool Mark" must not only be made from pure, new wool, but the dye fastness, pilling and other technical indicators of the fabric itself must also meet the standards set by the International Wool Bureau (IWS). standard. The “Pure New Wool Logo” is shown in Figure 21.

The International Wool Bureau also has the wool blending mark (when wool is blended with natural fibers, the new wool must be more than 50%, and when wool is blended with man-made fibers, the wool content must be no less than 60%). Launched in 1971, it is a quality guarantee for products with a high proportion of wool blends.

The International Wool Bureau’s work in China began in 1980. As of today, there are 470 pure wool mark licensed factories in China, spread across 20 provinces, municipalities and autonomous regions across the country.

The International Wool Bureau has determined through inspection and announced to consumers the first list of my country's first "counterfeit-free pure wool logo product stores", including 32 of the most influential stores in 10 major cities across the country.

The International Wool Bureau uses anti-counterfeiting technology to verify the authenticity of pure wool logo tags. The new technology is embodied in a 7mm square film that contains laser imaging capabilities. As long as you stick the film on the pure wool logo tag and take a photo with a portable electronic observer, you can immediately identify the authenticity.

This anti-counterfeiting technology was first used in mainland China and India. The International Wool Council teaches its skills to licensed manufacturers, retailers and management agencies in mainland China and India, and provides special hand-held electronic observers to protect the rights and interests of consumers and maintain the reputation of the pure wool mark.
