Cashmere is a very precious textile raw material, but many people do not understand the characteristics of cashmere, buy back cashmere to make up for a short time to find the ball down phenomenon, suspect that the clothes are not cashmere bluff. In recent years, cashmere sweater from The ball is also a hot spot for consumer complaints.
So why does cashmere sweater play ball?
The reason why a cashmere sweater loses piles is determined by the morphological structure of the fiber itself. If the processing machinery used and the manufacturing process are unreasonable, it will promote the phenomenon of pile-up and pilling.
The fiber is composed of a scale layer and a cortex layer. The scale has a certain height and thickness. Some of the edges are zigzag and shaped like barbs. It is easy to produce collusion and sticking of fibers in the process of wearing, resulting in pilling.
The fineness, length, and crimp of cashmere fibers are important process features. Compared with Australian wool, cashmere has a smaller fineness, a shorter length, and a smaller number of crimps, so that the fibers have a small cohesion in the yarn, and there are many exposed hairinesses, plus fibers. 1. The slippery slides away from the fabric under the action of external force to produce a piled ball.
Compared with wool, cashmere fiber, the fiber's shrinkage and friction coefficient are small, the friction between the fiber resistance is reduced, but because of the scale structure of cashmere fiber, making cashmere pure spinning or wool blended fabric, cashmere is easy from the fabric When the middle slip moves out, when the aggregates of the fibers are subjected to an irreversible external force, the fibers of the inverse scale tend to continue to move towards the roots, resulting in falling piles. Due to the ratcheting between the scales and the elasticity of the fibrous body, the fibers are mutually The staggered tangling of the balls also causes the felting of the animal fibers.
Cashmere fibers have poor electrical resistance and electrical conductivity. When the clothes are worn, the fibers rub against each other, causing the charge to accumulate in the fibers and generate static electricity. The fibers with a high dielectric constant have a positive charge, whereas they have a negative charge, such as chemical fibers and cashmere. When it is rubbed, the chemical fiber is negatively charged, and the cashmere fiber is positively charged. The fibers that do not have the same charge attract each other, and can easily cause the fabric to lose its pile. This phenomenon is particularly serious when the weather is dry.
In addition, in recent years, the price of cashmere has risen rapidly, and the processing of cashmere has developed rapidly. Under the seduce of considerable profits, local cashmere processing companies have begun to launch one after another. However, because some cashmere processing companies do not have good equipment and environment, they lack quality. The guarantee system, in the process of a large number of damage to the fiber, reducing the length of the fiber, resulting in a short fiber that is detrimental to the yarn quality and taking performance, greatly reducing the grade of the product, resulting in a serious cashmere pilling phenomenon after wearing the cashmere sweater.
Cashmere in the maintenance and collection should pay attention to the following points.
1, when the cashmere products are worn, pay attention to keep clean. Cashmere underwear should often gently fold, remove the dust, cashmere coat can be used soft brush static brush along the direction of brushing a brush gently, you can remove the dust, but also To prevent the locusts from being latent and damaging, and to make the plush cis-possible. In addition, the cashmere products should be washed with stains.
2. Cashmere products passing through must be washed, ironed, dried, and then stored before they are stored in the season. This can reduce the conditions and the scope of the activity of mold worms, and it can be used for insecticidal sterilization.
3, cashmere products, underwear can be folded, sealed with a plastic bag set, flat in the closet, the coat should be put on a plastic bag and hang in the closet.
4. Stored cashmere products should pay attention to shading to prevent fading, should always be ventilated, cool, beat dust, go wet, and can not be exposed to the sun. If the sun had to be allowed to dry and then put in the closet. At the same time inside the closet into the defense Mildew, anti-worm tablets, so as not to cashmere moldy insects.
5, washing methods. Because the cashmere fiber surface is composed of many scales, once the washing machine is used to stir cashmere products, it will make the cashmere products felting, destroying the fine performance of cashmere products. Therefore, cashmere products can not be washed with washing machines, The best dry cleaning, you can also hand wash. The method is as follows:
When the cashmere products are lightly soiled, the neutral detergent (shampoo, food wash, and special detergent for cashmere sweaters) is first poured into warm water at about 30°C, and the lotion is stirred evenly before being put into the clothes. Hand gently knead, cashmere products if stained with dye, etc., to send dry cleaners special treatment, washing.
Then, in the warm water about 40 °C several times until clean. Then add a little vinegar or softener in the water, it is best to put the washed cashmere products into a cloth bag in the washing machine dehydration 1-2 minutes.
Finally, the cashmere products were flattened and steamed at 120°C-140°C. The iron could not be directly contacted with the cashmere products. The cashmere products could be flattened and dried after shaping.
