Product Brief

Cashmere is the most valuable special fiber in animal fiber. More than half of the cashmere products in the world are produced in our country. Cashmere is very valuable, not only because of its rare yield, but also its fine quality and characteristics. Textile raw materials Can not match.

Cashmere has fine fineness, light, soft, glossy, smooth and waxy hands and strong natural scent. Therefore, cashmere is known as "the king of Mao".

Cashmere products are cashmere sweater, cashmere trousers, cashmere skirt, cashmere scarf, cashmere shawl, etc. because cashmere fiber has fine, light, soft, slippery, glutinous and other excellent characteristics, so that its products have comfortable wearing, beautiful appearance, elegant colors, velvet fullness, soft touch, slippery waxy, warm and so on the unique style of high-grade wool products.

crux index

1. fiber content. According to the textile industry standard, when a part of a product or product is made entirely of one fiber, the fiber content is expressed by "100%", "pure" and "full", and the allowable difference of fiber content is 0. Due to the variation of cashmere fiber morphology, cashmere will appear "suspected wool" phenomenon. The content of cashmere can reach 95% and above, and "suspected wool" less than 5% can be described as "100% cashmere", "pure cashmere" or "Cashmere". In the cashmere sweater spot checks, the fiber content is not qualified, but the phenomenon of 100% cashmere has occurred.

2. dichloromethane soluble substances. The soluble substance of dichloromethane is an oil agent, which comes from the woolen oil added to the posterior processing. According to the product standard of cashmere knitwear, the soluble substance of dichloromethane must be less than 1.7% in the first grade cashmere sweater, because cashmere knitwear is calculated by weight. If the oil content of cashmere sweater exceeds the standard, it will increase the weight of cashmere sweater, increase the selling price, and damage the interests of consumers in disguised form. In the spot check of cashmere sweater, a proportion of disqualified products was found to be unqualified because of the excessive solubility of dichloromethane.

3.pH value. The pH value is usually referred to as acid-base, which is used to indicate the pH value of the solution. The surface of human skin is weak acidic to prevent the invasion of germs. Therefore, the pH value of textiles is beneficial to human health between slight acid and neutral. According to the national mandatory standards, clothing for direct contact with the skin, its pH value can not exceed 7.5, pH value exceeds the standard will destroy the human body's skin weak acidic environment, cause itching, make the skin vulnerable to other pathogens, and even cause dermatitis. In the spot checks, the pH value exceeded the standard and was found to be unqualified products.

Usage and maintenance

1. use. As a high quality cashmere product, because its fiber is thin and short, its strength, wearability and pilling properties are not as good as those of wool. It is very delicate. Its characteristics are really like "baby" skin, soft, fine, smooth and elastic, but we must remember that it is tender, easy to break, and is not used properly, so it is easy to shorten the service life. When wearing cashmere products, special attention should be paid to reduce the greater friction. The matching coat with cashmere should not be too rough and hard, so as to avoid friction damage to fibers and reduce pilling or pilling.

2. maintenance. Cashmere is a kind of protein fiber. It is very easy to be eaten by insects. When collecting, it should be washed and dried, and placed a suitable amount of anti insect and borer. It should pay attention to ventilation and humidity. When washing, we should pay attention to the three elements:

1) neutral detergent should be selected.

2) the water temperature is controlled at 30 ~ 35 C;

3) be careful to rub lightly, do not exert force, rinse the water with clear water.
