What is sleeping yarn? What effect does it have on the beauty of the carpet
The pile is one of the main components of a carpet. In fact, the part that the buyer sees first is the pile of the carpet. When you touch the carpet, you are touching the pile of the carpet.
The texture of the carpet, both machine-made and handmade, is made of warp, weft, and pile threads. In this way, the weft thread is first passed through the warp thread alternately, providing a base for weaving the carpet with pile threads.
All machine-made carpets, except for kilims, are made of pile thread knots on the surface of the carpet. Only in kilims are the carpets that the carpet texture is completed after the warp and weft are intertwined. The pile thread, which some call pile thread, is made of various fibers. In handmade carpets, these threads are made of wool, cotton, and silk.
Synthetic fibers are used in the weaving of machine-made carpets. Synthetic fibers are very diverse and are cheaper than machine-made carpets.
What role does the pile yarn play in a carpet?
The presence of pile yarn is very important in the beauty, quality, and comfort of the carpet. The pile yarn with different types produces a variety of carpets. The importance of pile yarn in its comfort and seating is very high. So that the thicker and longer the pile yarn, the thicker the machine-made carpet is and the better it feels to sit, sleep, and lie on it. An example of this can be seen in Gabbeh carpets.
Gabbeh piles are woven from both thick yarns and are higher. For this reason, they are very comfortable carpets and are very suitable for those who do not want to use furniture. The height of the pile yarn is directly related to the thickness of the carpet. The longer the pile yarn, the thicker the machine-made or handmade carpet.
The warp thread is also very important visually. The design of the carpet is laid out on the warp thread. Therefore, the type of warp thread can have a great impact on the beauty and appearance of the carpet. In fact, the difference in the design of Iranian carpets lies in the difference in the use of threads in different colors. The beauty of any carpet depends more on the warp thread of the carpet than anything else. The warp thread makes up the largest part of any carpet and contributes a large share to the weight of the carpet. Therefore, it can be said that the quality of a carpet depends more on the type of warp thread than anything else.
Types of pile yarn
In handmade carpets, pile yarns are made of natural fibers. In machine-made carpets, synthetic fibers are used for pile yarn. There is a wide variety of these fibers, and each has its own special characteristics.
Acrylic, polyester, polypropylene, and filament yarns are among the most commonly used pile yarns in machine-made carpets. These yarns have several different quality grades, and their material determines the quality of the carpet.
Acrylic yarn
Acrylic yarn is one of the most widely used pile yarns in machine-made carpet weaving. These yarns are very similar to wool. At the same time, they are lighter and cheaper. Acrylic yarns have high dyeability. Machine-woven carpets with these yarns are of high quality. These yarns are used in the carpet, textile, and clothing industries. Acrylic yarns are used in regular and heat-set forms.
Currently, heat-set acrylic yarns are the best type of pile yarn in machine-made carpet weaving. Acrylic yarns are naturally high in quality and durability. However, their quality is further enhanced during the heat-set process. In this process, the pile yarn is placed in hot steam tunnels before entering the weaving cycle, which increases its quality and durability.
The most important features of heat-set acrylic yarns are:
The least amount of pilling among machine-made carpets
Long life
High resistance to moisture and washing
Resistance to abrasion and wear
Color stability
High resistance to heat
No unpleasant odor
High elasticity and minimal tearing during weaving
More softness than other synthetic fibers
Non-allergenic
High reversibility
This is the most important feature of carpets woven with acrylic yarns, which makes these carpets among the best examples of machine-made carpets and, of course, the most expensive.
Polyester yarn
Like acrylic yarns, these yarns are also used in other industries in addition to being used as carpet pile yarn. Polyester yarns are produced in different quality grades. These yarns are used in the production of machine-made carpets, especially fancy and modern carpets. In terms of quality, they are after acrylic yarns. Polyester yarns can also be heat-set. In this case, the pile yarn is of higher quality.
The main features of polyester yarns are as follows:
High durability
Non-allergic
High washability
High color stability
Softness and softness
Reversibility
Polypropylene yarn
Polypropylene yarns are another yarn used in the carpet weaving industry. These yarns are mostly used as pile yarn in fancy and machine-made carpets. In terms of material and quality, they are more similar to polyester yarns. They have good resistance. They are also more shiny in appearance.
The most important features of polypropylene yarns are:
High resistance to acids and alkalis
Resistance to washing
Reversibility
Good color stability
Filament Yarn
Filament yarns are another type of pile yarn in machine-made carpet production. Filament yarns are produced based on polyester yarns and polypropylene yarns. These yarns are bulked up and made thicker using a special method. Filament yarns have higher quality and durability than polyester and polypropylene yarns. In fact, we can say that polyester filament and polypropylene filament yarns can compete with heat-set acrylic yarns.
The following are the main features of filament yarns:
No pilling
High gloss
Resistant to washing
High reversibility and tear resistance
Color stability
High heat resistance
Non-allergenic
In machine-made carpets that use filament fibers for the pile, they are of high quality and are correspondingly more expensive.
The relationship between pile yarn and carpet thickness and density
The thickness of a machine-made carpet depends on the height of the pile yarn. The longer the pile yarn, the thicker the carpet, and vice versa, the shorter the pile yarn, the thinner the carpet. Thick pile yarn is used for Gabbeh carpets. Thick yarns are suitable for carpets with low density. The higher the carpet density, the thinner the carpet. This means that both the pile yarn is thinner and its height is lower.
High-density carpets such as 1500-thread carpets or 1200-thread carpets are the thinnest classic machine-made carpets. This means that they have thinner yarns. The height of the pile yarn in 1500-thread carpets is 7 mm. After that, 1200-thread carpets with a height of 8 mm are the thinnest carpets. 1000-thread carpets have a height of 10 mm. The 700-needle carpet is 11 mm, followed by the 500-needle carpet with a height of 12 mm, which is the thickest machine-made carpet.
Machine-made kilim carpets have a very low height, about 3 mm, because they do not have pile threads. This height is related to the warp and weft threads. The kilim carpet has high resistance, but due to the lack of pile threads, it does not provide a comfortable and soft seating area.
The role of pile thread height in the use of machine-made carpets
One of the important issues in choosing and buying a carpet is its suitability for the space used. Among them, pile threads are very important both in terms of material and height. Thin carpets with high density are the best choice for the reception area. These carpets have short pile threads, and for this reason they are not very soft and comfortable carpets and are mostly decorative. 1200-needle carpets and 1500-needle carpets are examples of carpets.
The delicacy and thinness of the carpet is so much that these carpets are used for tableau carpets; Because the pile type of these carpets has a double beauty.
The best carpets for the bedroom and living room, where the comfort of the carpet is a priority, are 700-count carpets or Gabbeh carpets. These carpets create a softer feeling due to the higher pile height.
700-count carpets are not an ideal option for the kitchen; because they do not have a high density and more dust can penetrate the carpet texture. 1000-count carpets are the best option for this reason, these carpets are both beautiful enough and have a good thickness. Kilim carpets are also used in high-traffic spaces because they do not have pile yarn, because they are very resistant.
How to identify the pile yarn of a machine-made carpet?
The pile yarn plays a key and important role in a machine-made carpet. More than eighty percent of a machine-made carpet is made up of its pile yarn. Therefore, it is important to know what fibers are used for the pile yarn. It is not an easy task to distinguish a good machine-made carpet and its pile. Of course, things like the lack of fluff and the touch of the carpet and the absence of a bad smell can determine the quality of the pile and carpet to some extent. However, it is difficult to accurately identify the type of pile of the carpet, and in this case you have to trust the carpet seller. Therefore, you should buy carpets from a reliable store. Dariush Carpet Store is very reliable in this regard.
