Core spun yarn is a new type of yarn made from two or more kinds of fibers. In recent years, it’s more and more used in the textile industry as a substitute for expensive natural fiber like wool yarn. More and more brands are also gradually accepting the core spun yarn, using it to manufacture clothes.
As a core spun yarn manufacturer, we independently develop and produce various types of it, such as high-twist core-spun yarns and rabbit hair core-spun yarns. The production process combines the characteristics of various yarns, and the product can simulate or even exceed the performance of a certain fiber, with great advantage at price. In 10+ years of development, we have accumulated a lot of production experience and can recommend or develop appropriate core-spun yarn specifications according to customers’ production needs.
Core-spun yarn is widely used in the knitwear manufacturing industry.
The core-spun yarn definition in the textile industry is: A core-spun yarn refers to a composite yarn combined by a core yarn and an outer yarn; generally with a filament as a core yarn, the short fiber is an outer yarn.
2. Core spun yarn properties
Characteristics of core-spun yarn: the combination of core-spun fiber and core-spun yarn can give play to their advantages, make up for the shortcomings of both sides, and optimize the structure and characteristics of the yarn.
core spun yarn advantages
(1) It feels very comfortable, simulating the feel of expensive fibers such as cashmere, and can even achieve the effect of being fake.
(2) Cheap price is the biggest advantage of core-spun yarn. Guess how cheap it is? For example, the price of woollen wool this year is about 220 yuan per kilogram; for cashmere, it is about 850 yuan per kilogram; even the yarn with 60% wool is more than 40 yuan per kilogram. The price of core-spun yarn is only RMB 30 per kilogram.
These two biggest advantages have made core-spun yarn a kind of yarn that has been particularly favored in the past two years. Regardless of whether it is marketed or branded, many clothing manufacturers are using it. Of course, many high-end clothing may not use core-spun yarn, after all, the textile industry knows that it is a low-end category of yarn.
core spun yarn disadvantages
To be honest, as a core-spun yarn manufacturer, we understand all aspects of its properties, and really can’t find out its big shortcomings. You said that core-spun yarn pilled, it does pilling; but it is undeniable that wool and cashmere will also pilling.
The only disadvantage of core-spun yarn, in my opinion, is that it is heavier. If you use it to make clothes, there will be the following unsatisfactory aspects:
The fluffy feeling of clothes will not be as good as wool clothes.
Clothes cannot be made into sweaters that are light and thick. If they are thick, the clothes will be very heavy, and they will feel tired when worn on the body.
3. core spun yarn type
3.1 Classification by product use
It can be divided into core-wrapped yarn for sewing, core-wrapped yarn for rotten fabric, elastic fabric (including knitted fabric, woven fabric) core-wrapped yarn, fancy core-wrapped yarn (such as hollow core-wrapped yarn, color core-wrapped yarn, cyrofield core-wrapped yarn, bamboo core-wrapped yarn, etc.), functional and high-performance fabric core-wrapped yarn, etc.
3.2 Classification by core yarn filament
Generally, it can be divided into rigid core-spun yarns and elastic core-spun yarns. The former has polyester, acrylic, vinylon (including water-soluble vinylon), nylon, etc., and the latter has spandex, PTT fiber, PBT fiber, DOW XLA elastic fiber, etc.
3.3 Classification by sheath yarn fiber
Usually cotton, wool, silk, hemp (including ramie, flax, hemp, etc.), colorful cotton and other natural fibers; Sticky fiber, MODAL, TENCEL, soybean fiber, milk fiber, bamboo pulp fiber, polyester fiber, acrylic fiber and all kinds of colored chemical fiber can be used for core-spun fiber.
3.4 Classification by spinning equipment
At present, ring spinning, rotary spinning, friction spinning, air jet spinning and other spinning devices can be added to produce all kinds of core-spun yarn. Spinning devices are basically the same.
3.5 Classification according to filament (core yarn) content
Filament content in core-spun yarns is the main index of core-spun yarns, which has great influence on yarn performance and cost. Generally, filament content below 10% is called low ratio core-spun yarn; 10%~40% medium ratio core-spun yarn; Over 40% is called high ratio core-spun yarn. Elastic core-spun yarn content is generally less than 10%, 3%~5%, the higher the proportion, the higher the cost. Pure polyester sewing core-spun yarn, core-spun yarn ratio up to 50~60%. The content of core yarn used in rotten fabric is 40~60%, and the content of general rigid core-wrapped yarn is 20~40%. Core yarn content should not be too high, is restricted. Theoretically, the covering width of the outer fiber should be larger than the surface perimeter of the core yarn, otherwise “Ruth” defects will occur.
3.6 Classification according to yarn density
In the same classification as traditional yarns, core-spun yarns of 32tex and above are classified as coarse special core-spun yarns, 21-30tex medium special core-spun yarns, 11-20tex fine special core-spun yarns. The core-spun yarn is 16~70tex.
4. The difference between core spun yarn and covered yarn
The difference between core-spun yarn and covered yarn, we take spandex core-spun yarn and spandex covered yarn as examples:
Spandex core-spun yarn is spandex wrapped with short fibers, with spandex as the core and non-elastic short fibers outsourcing. When the spandex core-spun yarn is stretched, the core yarn is generally not exposed.
Spandex covered yarn is an elastic yarn formed by covering the spandex with the filament of chemical fiber, which is also made of spandex as the core, and the non-elastic staple fiber or filament is wrapped in a spiral manner to cover the elongated spandex yarn. It has core exposed under tension
The core-spun yarn has poor elasticity, but the core yarn is not easy to be exposed to produce aurora; covered yarn is easy to produce aurora, but the elastic elongation ability is better.
Seeing this, I believe you already know something about core spun yarn. If you want to know more about core spun yarn, then this article on how core spun yarn is made may be able to help you.
