What Is PBT
PBT yarn is a unique category of yarn which takes the full advantage of its polymer polybutylene terephthalate. This yarn facilitates the manufacturing of high comfort garments, carpets, and automotive fabrics. The fabric provides added comfort and seamless movement. This innovative yarn ensures a comfortable microclimate around the body. The yarn creates a finished product that is breathable and has great elasticity and superior color absorption. Due to their low water absorption rates (about 0.4% of h2o), PBT yarns are sweat resistant and their elasticity stays unaffected when exposed to moisture.
Properties of PBT
PBT yarns have the following properties:
PBT is basically a textured polyester with a nylon crimp characteristic.
PBT a high elastic, friction-textured material.
PBT has good stretch properties and unique recovery properties.
PBT is a high-resistant fiber that is both soft and elasticis high.
PBTresistant to perspiration and humidity.
PBT has both very low humidity take-up levels (only 0.4% approx.) and dries very quickly.
PBT elastic recovery with low subsequent ductility.
PBT good stretching with problem-free working properties.
PBT resistant to chlorine, good base resistance, no loss of fastness through UV rayslight-fastness similar to that of a polyester.
The Influence of PBT Yarn on the Weaving Process
When PBT filament has been combined with thicker yarns as weft in weaving in certain sequences, the cross marks/lines have appeared in the fabrics after thermal treatment, except when used in combination with similar types of synthetic fibers. When PBT filament has been combined with each weft, the shrinkage of the fabric after thermal treatment was too high (high elasticity).
When PBT is used in folded yarn in combination with natural yarns, at least the folding preparation stage is required. When folded PBT yarn was used as each weft, the shrinkage of the fabric after treatment was too high (high elasticity).
Using PBT as core surrounded by other fibers in a core-spun yarn has proven to have the least disadvantages: No marks/lines on the fabric surface after treatment, easy dyeing; can be used in sequences as weft and thus the degree of elasticity can be planned/controlled. The production price of the fabric increases, nevertheless, the percentage of PBT yarn in the fabric is as low as possible. The use of PBT yarns does not cause any problems in the weaving process, as the elasticity of yarns is gained after thermal treatment.

● Due to their low water absorption rates (about 0.4% of h2o), PBT yarns are sweat-resistant and their elasticity stays unaffected when exposed to moisture.
● It can also be equipped with elastic and non-elastomeric yarn which has high stretchability and superior elastic recovery. These characteristics are a result of multidimensional bulking processes that are not only linear, unlike an ordinary elastic yarn.
● Fabrics that are manufactured with this fiber even when the PBT content does not exceed 30 to 35%, turn out to be the ideal body-hugging garments that are breathable and comfortable. This has helped the fashion industry create versatile designs and countless clothing styles for the finished products.
PBT yarns are used in:
Weaving as weft insertion yarn (non or slight intermingled).
Weaving as warp yarn (sized or high/strong intermingled).
Circular knitting, weft knitting and warp knitting.
Narrow weaving and braiding.
Covered yarn applications.
PBT yarns are used mainly in stretch required fabrics, in jeans, lingerie, underwear, silk stockings, carpet for pile, sportswear.
Due to their excellent elastic recovery and resistance to corrosion, PBT yarns stand a good chance of being an alternative to elastane/rubber covered yarns in applications where stretch and recovery properties are in high demand.
PBT: Excellent Elasticity and Advantages over Traditional Materials
The elasticity of PBT yarn manifests in multiple aspects:
Soft and comfortable: The softness of PBT yarn originates from the unique arrangement of its molecular structure, allowing better fiber sliding and increasing fabric softness. PBT yarn boasts excellent anti-static properties, reducing static friction between fibers and further enhancing fabric smoothness. This soft and comfortable feature is crucial for close-fitting garments like underwear and sportswear, offering a pleasant wearing experience and minimizing skin irritation.
Strong wrinkle resistance: The high tenacity and resilience of PBT yarn contribute to its outstanding wrinkle resistance. Compared to traditional materials, PBT yarn is less prone to permanent deformation under force or compression. Therefore, slight wrinkles generated during wearing can quickly recover. This wrinkle resistance not only maintains a neat garment appearance but also reduces the need for ironing, extending the garment's lifespan and lowering maintenance costs.
Shape stability: The stable molecular chain structure of PBT yarn endows it with a high melting point and glass transition temperature, enabling it to maintain a stable shape under high temperatures. This shape stability prevents garments from deforming due to heat or moisture, preserving the intended visual effect designed by the designer. Consequently, PBT yarn is advantageous in crafting garments that require shape retention, such as suits and dresses, delivering a long-lasting wearing experience.
Wide adaptability: PBT yarn possesses extensive adaptability, suitable for various types of clothing designs and other fields like home textiles and automotive interiors. Its excellent elasticity allows fabrics to better fit various shapes and sizes of object surfaces, providing designers with greater creative space.
PBT yarn features good wear resistance and chemical resistance, meeting the requirements for material strength and durability in different fields, thus having broad application prospects in industrial applications.
PBT Yarn Processing Manufacturing Process
Preparing the fibers
Fibers are shipped in bales, which are opened by hand or machine. Natural fibers may require cleaning, whereas synthetic fibers only require separating. The picker loosens and separates the lumps of fiber and also cleans the fiber if necessary. Blending of different staple fibers may be required for certain applications. Blending may be done during formation of the lap, during carding, or during drawing out. Quantities of each fiber are measured carefully and their proportions are consistently maintained.
Carding
The carding machine is set with hundreds of fine wires that separate the fibers and pull them into somewhat parallel form. A thin web of fiber is formed, and as it moves along, it passes through a funnel-shaped device that produces a ropelike strand of parallel fibers. Blending can take place by joining laps of different fibers.
Combing
When a smoother, finer yarn is required, fibers are subjected to a further paralleling method. A comblike device arranges fibers into.
Drawing out
After carding or combing, the fiber mass is referred to as the sliver. Several slivers are combined before this process. A series of rollers rotating at different rates of speed elongate the sliver into a single more uniform strand that is given a small amount of twist and fed into large cans. Carded slivers are drawn twice after carding. Combed slivers are drawn once before combing and twice more after combing.
Twisting
The sliver is fed through a machine called the roving frame, where the strands of fiber are further elongated and given additional twist. These strands are called the roving.
Spinning
The predominant commercial systems of yarn formation are ring spinning and open-end spinning. In ring spinning, the roving is fed from the spool through rollers. These rollers elongate the roving, which passes through the eyelet, moving down The sliver is fed through a machine called the roving frame, where the strands of fiber are further elongated and given additional twist. The predominant commercial systems of yarn formation are ring spinning and open-end spinning. Open-end spinning omits the roving step.

and through the traveler. The traveler moves freely around the stationary ring at 4,000 to 12,000 revolutions per minute. The spindle turns the bobbin at a constant speed. This turning of the bobbin and the movement of the traveler twists and winds the yarn in one operation.
