In the process of wearing sweaters with various fibers, pilling and pilling will occur on the surface of fabrics due to the wear of external forces. This phenomenon is inevitable in natural fiber fabrics, and it is also an urgent textile technical topic in the world.
There are many factors that affect wool pilling:
1, in the fabric, fibers are long and short, and pilling is caused by some short fibers being ground and shrunk.
2. Different fabric structures of woolen cloth will also produce different degrees of pilling phenomenon; Generally speaking, flat needles and fish scales are not easy to pilling, single-sided and flat needles are easy to pilling, and loose density is easy to pilling.
3. Raw material factors of wool fabric: Australian wool has good fineness, soft hand feeling and easy pilling, while domestic wool has poor fineness and hand feeling and is not easy to pilling.
Therefore, in the contact process of woolen clothing, it is necessary to minimize the friction with rough objects (especially the friction between wearing unlined coats and sweaters). Secondly, pilling does not affect the quality. The phenomenon of new clothes is more obvious in the early stage of wearing. You can cut it with small scissors, pull it gently with your fingers, or shave it off with a special electric razor and wash it. This phenomenon will gradually be alleviated.
There will always be friction when wearing, and the fibers in the fabric will be loose, intertwined and kneaded into a ball to form a fluffy ball. This phenomenon exists more or less in natural fiber and chemical fiber fabrics, and the national textile industry standard only takes pilling as a reference index, not as an assessment index. Pilling mainly affects the appearance and is harmless to the internal quality, which is also an urgent textile technical problem in the world.
Several points to be grasped in dealing with pilling of wool fabric;
■ The simplest method:
Transparent glue can be used, and it is the kind that is wide and sticky.
Also, besides balls, there are sweaters on the market. You can buy one for use.
■ How to prevent pilling of wool fabric?
Pilling is a characteristic of wool products. In the process of wearing and using wool fabric, the short fibers protruding from the fabric surface are easy to entangle into balls, which affects the appearance and causes felting, especially for high-grade products, which will aggravate this trend. Pilling is related to raw material properties, spinning and dyeing process, knitting structure and wearing mode. The influence of raw materials, spinning and dyeing on pilling is very complicated, and its mechanism is still under discussion.
This has a negative impact on the style and quality of wool products, so experts advise consumers:
1. When knitting fine wool (cashmere type), mercerized wool and Tencel series wool, the knitting density should be appropriately increased and the pattern structure should be less.
When wearing a sweater, the clothes should be smooth inside and outside.
3. Dismantle and wash frequently. Generally compiled once every 2-3 years. Use neutral detergent or soap powder when washing. When the water temperature is below 50℃, don't rub it, but dry it evenly.
4. If you have special anti-pilling needs, it is recommended to buy blended and woolen pure wool.
■ Anti-pilling method for washing sweaters:
(1) When washing, put the inside of the sweater outward to reduce the friction on the surface of the sweater, which can prevent the sweater from pilling.
Washing sweaters with shampoo can make them supple and natural.
■ Sweater trimmer:
What should I do if many sweaters pilled in winter? Use the new sweater trimmer!
The season has changed, and I began to take out sweaters, coats and other clothes. What should I do if I find that many clothes are fuzzed? Use a hairball trimmer! Can effectively remove all kinds of stubborn hair balls. The use method is simple and does not damage the fabric. According to the thickness of the sweater, the ball is divided into three grades: high, medium and low. Now the owner who owns it can make your pilling jersey look brand-new by energizing it! It is also equipped with a chip storage box device, which is sanitary and convenient. There is a rechargeable hairball trimmer, so you don't have to go to the supermarket to buy batteries. ......
Cause analysis of pilling and pilling of sweaters;
The mechanism of pilling is that under the action of various external forces such as friction and tension, wool fibers in wool yarn are easy to hook up and form a ring or a single head. After repeated rubbing, wool fibers are intertwined to form a ball. The degree of pilling mainly depends on:
1. Product materials
Low-grade raw materials with short length, uneven fineness and high short hair rate are all listed here.
2. Spinning process control
Spinning mode, fiber characteristics and yarn twist determine the amount of fiber protruding from the yarn surface. For products made of low count wool, it is often seen that the yarn surface is mixed with coarse cavity hairs, which is easy to pilling.
3. Fabric structure
Sweater products are knitwear, and the fabric density and the tightness of loop structure also affect the pilling of sweaters. Fabric with flat and smooth surface, such as flat knitted fabric and rib fabric, has stronger pilling resistance than fabric with uneven surface, such as fatty flower fabric and striped fabric.
Washing and wearing
The washing method of sweaters is sometimes an important reason for pilling. Products that are not marked "machine washable" must be "carefully washed by hand" and must not be washed in the washing machine to avoid trouble, because under the strong action of the washing machine, the friction is intensified, leading to pilling. In general, the friction pilling between elbow and rib is obvious.
To some extent, pilling is the "twin" of all wool products. In order to reduce pilling, our factory not only strictly controls raw materials, but also adopts its own spinning production technology, forming its own unique production technology in product weaving and finishing, thus making Verma products seldom pilling.

■ Maintenance of cashmere sweater:
Cashmere is a very precious textile material, but many people don't know its characteristics. After buying it and mending it for a short time, they found the phenomenon of falling wool and pilling, and suspected that the clothes were not cashmere. In recent years, pilling of cashmere sweaters is also a hot spot of consumer complaints.
So why does the cashmere sweater fall off and pilling?
The pilling reason of cashmere sweater is determined by the morphological structure of fiber itself. If the processing machinery and production technology used are unreasonable, the pilling phenomenon of cashmere will be more serious.
Fiber consists of scales and cortex. Scales have a certain height and thickness, and some edges are serrated and shaped like barbs. In the process of wearing, the fibers are easy to hook and stick together, resulting in pilling.
The fineness, length and curl of cashmere fiber are important technical characteristics. Compared with Australian wool, cashmere has smaller fineness, shorter length and less curl, which makes the fiber have less cohesion in the yarn and more external feathers. In addition, the fiber slides down from the fabric under the action of external force, resulting in pilling.
Compared with wool, the fiber shrinkage and friction coefficient of cashmere fiber are smaller, and the friction resistance between fibers is reduced. However, due to the scale structure of cashmere fiber, cashmere is easy to slip out of the fabric when it is spun pure or blended with wool. When the fiber body is subjected to non-directional external force, the fiber stressed by the anti-scale is easy to move to the root continuously, causing cashmere to fall off. Due to the interlocking between scales and the elasticity of fiber body, the fibers are intertwined into a ball.
Cashmere fiber has poor electrical resistance and conductivity. When clothes are worn, the fibers rub against each other, which leads to the accumulation of charges in the fibers and the electrostatic phenomenon. Fibers with high dielectric constant are positively charged, and vice versa. For example, chemical fibers rub cashmere, chemical fibers are negatively charged and cashmere fibers are positively charged. Fibers with different charges attract each other, which is easy to cause fabric pilling, especially when the weather is dry.
In addition, the price of cashmere has risen rapidly in recent years, and cashmere processing has developed rapidly. Attracted by considerable profits, cashmere processing enterprises all over the world have launched one after another. However, due to the lack of good equipment, environment and quality assurance system, some cashmere processing enterprises have damaged a lot of fibers during processing, and the fiber length has decreased, resulting in short fibers that are harmful to yarn quality and wearability, which greatly reduces the grade of products. After wearing cashmere sweaters, cashmere pilling is serious.
Cashmere should pay attention to the following points in maintenance and collection.
1, cashmere products should be kept clean when worn. Cashmere underwear should always be folded gently to remove dust. Cashmere coat can be brushed gently along the direction of wool head with soft wool electrostatic brush, which can remove dust, prevent the lurking and destruction of moths and make wool supple. In addition, cashmere products stained with stains should be washed in time.
2. When cashmere products need to be stored in season, they must be washed, ironed and dried before storage, which can reduce the conditions and scope of mold and moth activities, and can also kill insects and sterilize.
3. When cashmere products are stored, underwear can be folded, sealed with plastic bags and placed flat in the wardrobe. The coat should be put in a plastic bag and hung in the closet.
4. Stored cashmere products should be protected from light to prevent fading. They should be ventilated, sheltered, dusted and dehumidified, and should not be exposed to the sun. If it is sun-dried, let it dry thoroughly before putting it in the closet. At the same time, mildew-proof and moth-proof pieces are placed around the wardrobe to prevent cashmere products from being affected with moisture, mildew and insects.
5. Washing method. Because the surface of cashmere fiber is composed of many scales, once cashmere products are stirred and washed by washing machine, they will be felted and their excellent properties will be destroyed. Therefore, cashmere products must not be washed by washing machine, and it is better to dry-clean or hand-wash. The method is as follows:
When the cashmere products are slightly stained, first pour the neutral detergent (shampoo, meal washing, cashmere sweater special detergent) into warm water at about 30℃, then put it into the clothes and pat it gently with your hands. If cashmere products are stained with dyes, they should be sent to dry cleaners for special treatment and washing.
Then wash it several times in warm water at about 40℃ until it is clean. Then add a little vinegar or softener to the clean water. It is best to put the washed cashmere products into a cloth bag and put them in a washing machine for dehydration 1-2 minutes.
Finally, the cashmere products are smoothed and ironed with a steam iron at 120℃- 140℃. Iron can't directly contact cashmere products. Cashmere products can be flattened and dried after shaping.
