Introduction to Sorona PTT
Sorona PTT (polytrimethylene terephthalate) is a thermoplastic that can be spun into both fibers and yarns. Sorona PTT belongs to a class called aromatic polyesters.
In both carpet and textile markets, Sorona PTT combines the chemical resistance characteristics that you can get from a polyester with the elastic recovery and resilience of nylon. Sorona PTT also offers inherent stain resistance, is continuously printable and dyeable without speciality chemicals in a full colour range.
Furthermore, Sorona PTT has a good colour fastness against uv light, ozone and nox. Sorona PTT provides lower water absoroption and has the potential to be recycled.
Sorona PTT Yarn Extrusion in the Project for Durable Biobased Plastics
Polytrimethylene terephthalate (PTT) is a linear aromatic polyester derived from the polycondensation of 1,3-propanediol (trimethylene glycol, 3G, or PDO) and, either terephthalic acid (PTA), or dimethyl terephthalate (DMT).
The trimethylene glycol monomer derives from a renewable route, resulting in a content of renewable carbon in the polymer of 20 to 37 wt%. The chemical composition is: Other acronyms for the same polymer are: PTMT (polytrimethylene terephthalate) and PPT (polypropylene terephthalate). Compared to PET, the PTT has - because of its zigzagged structure in the polymer chain, an intrinsically higher elasticity and maximum elongation.
Melting temperature: 227°C
Melt enthalpy: 54 J/g
Thermal stabiliy: 365°C
Crystallisation temperature: 165°C
Melt volume index @ 240°C: 15.9 cc/10 min
Melt volume index @ 250°C: 22.7 cc/10 min
PTT is a polyester and hence sensible to hydrolysis at heating above the fusion point. Therefore it was dried below 200 ppm.
Yarns were formed with a titre between 48 and 130 tex (15-40dpf). During the extrusion it was observed that the final line speed had to be limited to obtain a good affinity to spinning. The draw ratio could be high, ranging from 2.4 to 4.
The yarns made from the PTT had a tensile strength between 15 and 23 cN/tex. Because of their chemical structure, these yarns are characterised by a high elongation rate at break: yarns with a tensile strength of 20 cN/tex or more show a elongation rate at break of at least 45%.
Properties of Sorona PTT
Sorona PTT is said to have the natural and comfortable hand feel, good tension and elasticity, and it can be dyed at low temperature.
Sorona PTT also has high washing fastness, good antistatic performance, and it can be used in blended yarns with natural fibres such as wool.
It combines the advantageous performance of the nylon elasticity and softness, as well as the acrylic fibre fluffy and polyester anti pollution. It not only can be widely used in clothing and other textiles, but also has great potential for market development in the medical nonwoven field.

As Sorona PTT products are put into the market, the application of Sorona PTT has been rapidly developed, the main application areas.
Home textile fabrics: Good tensile recovery, easy dyeing, stain resistance and resilience.
Carpet: Sorona PTT has good resilience, stain resistance, low static electricity, abrasion resistance, low water absorption, which is very suitable for carpet, with abrasion resistance equal to or better than nylon, no stain and washing problems, and greatly reduces environmental pollution. In addition to the conventional carpet applications, the application of Sorona PTT in the field of automotive carpet should not be ignored.
Clothing: Sorona PTT has strong softness, stretchability, bright color and durability, suitable for knitted fabrics, woven fabrics, hosiery and underwear, lining, denim, swimwear, etc.. It is suitable for knitted fabrics, woven fabrics, hosiery and underwear, lining, denim, swimwear, etc. The clothing made of it is comfortable to wear, comfortable to move, soft to the touch, quick drying, non-iron, very much in line with the requirements of modern people's personalized life.
Spunbond nonwoven fabric field: The unique performance of PTT is suitable for spunbond nonwoven field.
Sewing thread: One of the most recent application areas is sewing thread, which will give added value to garment products with its
Sorona PTT can also be used as curtains, bedding, mosquito nets, sofa covers, car interiors and other products. It can also be used as construction safety nets, fishing rods, tennis rackets, etc.

Sorona PET (poly(ethylene terephthalate)) is one of the synthetic semi-aromatic polyesters and has terephthalic acid and ethylene glycol units in main chain. PTT (poly(trimethylene terephthalate)) is also a synthetic aromatic polyester with terephthalic acid and propylene glycol units. Both of PET and PTT are thermoplastics and they are used for various applications such as clothes and bottles. Although the term "polyester" is a category of polymers containing the ester linkages in their main chains, most commonly it refers to PET. PET and PTT are prepared by a polycondensation method from the corresponding monomers.
Performance: The strength and other properties of recycled polyester fiber are poor while polyester is relatively good.
Raw material: Recycled polyester is made of recycled materials (PET bottle pieces, foam, etc.), then granulated, and then drawing. Polyester is esterified into fiber by chemical raw materials PTA and MEG polymerization.
Polyester yarn refers to the yarn spun from polyester as raw material. Polyester is a kind of fiber made from a polymer by spinning. At present, it mostly refers to the fiber made from ethyl phthalate as raw material, which is shortened as "PET" fiber by the English name of the raw material "compulsory terephthalate".
Recycled polyester staple is the use of polyester fabric, waste polyester bottle flakes, spinning waste, bubble material, raw material, pulp lump do waste bottle after crushing, washing, a mixture of all kinds of materials after drying, melting extrusion, spinning, winding, cluster, drawing, crimping, flabby heat styling, cut off after the formation of the different length of polyester staple fiber.

The Manufacturing Method of Sorona PET
Sorona PET is an eco-efficient performance fiber made in part from annually renewable plant-based ingredients. It is used primarily in fiber applications, including textiles for apparel and home, office and automotive interiors, residential and commercial carpeting and automotive mats.
Sorona PET is a comfort stretch knitwear and woven material with soft, flexible, and stain resistant properties. It's spandex-FREE, yet provides exceptional stretch and recovery even after repeated stretches and washes.
Sorona PET fibers used for fabrics in T-shirt and hoodies also provide softness and volume, are quick to dry and resist fading for long-lasting, vibrant colors.
Sorona PET is produced with PDO—a building block with endlessly versatile potential— and using a biological process. 37% of the polymer is made using annually renewable plant-based ingredients. The revolutionary Bio-PDO compound turns a formerly chemical process into an eco-efficient biological one. Compared to Nylon 6 it uses 30% less energy and releases 63% fewer greenhouse gas emissions.
The process begins by harvesting crops and then extracting sugar or glucose from them. Microorganisms are added to the glucose to begin a fermentation process (similar to the process of alcohol). Fermentation replaces chemical synthesis, producing PDO (1,3-Propanediol) in a natural way. TPA (terephthalic acid) is added to the Bio-PDO, creating a molecular bond. The result is Sorona PET: a revolutionary, high-performance polymer whose positive impact is felt by yarn spinners, manufacturers, designers, and consumers across the globe.
