JIANGYIN HUAHONG CHEMICAL FIBER CO., LTD.

Background Our company recently completed a successful export project delivering high-quality Polyester Staple Fiber to a leading textile manufacturer in Pakistan. The buyer required stable, high-performance raw materials for spinning and non-woven applications, and they were particularly focused on fiber uniformity, color consistency, and production efficiency. Product Specifications Delivered We supplied three popular specifications widely demanded in the Pakistan textile industry: 1.2D × 38MM SD RW Polyester Staple Fiber 1.2D × 32MM SB Polyester Staple Fiber 1.2D × 51MM SD RW Polyester Staple Fiber These specifications are known for excellent spinnability and compatibility with common blending processes used in Pakistan’s spinning mills. Local Market Insight The Pakistan market favors reliable and cost-effective synthetic fibers due to its strong textile and garment export economy. Buyers often look for: Stable denier and cut-length control for smooth production Consistent whiteness and raw white color (RW) Soft hand-feel for blended yarns High durability and uniformity, especially for ring spinning and open-end spinning Good dyeing performance, particularly when combined with Cationic Dyeable Polyester materials for differentiated fabrics Our Polyester Tow and Polyester Staple Fiber offerings aligned well with these preferences, enabling the customer to maintain a high level of output quality. Customer Feedback The Pakistani buyer expressed strong satisfaction with the shipment: Fiber quality met international standards Minimal variation in denier and length Strong performance during spinning, reducing yarn breakage Stable supply and timely delivery Competitive pricing compared with regional alternatives The customer highlighted that the 1.2D × 38MM and 1.2D × 32MM fibers were especially suitable for fine-quality yarns, while the 1.2D × 51MM material performed well in their non-woven product line. Results After incorporating our Polyester Staple Fiber into their production: Yarn quality improved by over 10% based on their internal evaluation Production efficiency increased due to fewer stoppages The customer expanded repeat orders for continuous supply This cooperation further strengthened our reputation as a reliable exporter of Polyester Tow, Polyester Staple Fiber, and specialty products like Cationic Dyeable Polyester in the South Asian market. Conclusion This project demonstrates how consistent product quality, understanding of the Pakistan textile market’s needs, and stable supply capabilities can create successful long-term partnerships. We continue to support our clients in Pakistan with competitive solutions for spinning, weaving, and non-woven applications.

Background Our company recently completed a successful export project supplying high-grade Polyester Staple Fiber to a well-established spinning and nonwoven manufacturer in Turkey. As one of the most dynamic textile hubs in Europe and the Middle East, Turkey demands consistent, high-performance fiber materials that can support fast production lines and premium export-oriented fabrics. Product Specifications Supplied We delivered several specifications that are particularly popular among Turkish textile buyers: 1.2D × 38MM DDB Polyester Staple Fiber 1.5D × 38MM SD RW Polyester Staple Fiber 1.2D × 38MM DDB AAA Polyester Staple Fiber 1.2D × 38MM DDB TOW 3D DDB Polyester Tow TOW 6D DDB Polyester Tow 1.4D × 38MM DDB AAA Polyester Staple Fiber These specifications provide excellent uniformity, stable denier, and smooth spinnability—key requirements for high-speed spinning operations in the Turkish textile sector. Market Insight: What Turkish Buyers Prefer Turkey’s textile industry covers spinning, knitting, weaving, home textiles, and technical fabrics. Local buyers commonly prioritize: High color consistency, especially for deep-dyed and dope-dyed black (DDB) applications Stable cut length and denier, suitable for ring spinning and open-end spinning Low impurity and high uniformity, reducing machine stoppage Strong compatibility with blending, including cotton and Recycled Polyester Staple Fiber Preferred use of quality-assured Virgin Polyester Staple Fiber for premium yarn Increasing interest in Easy Cationic Dyeable Polyester and Cationic Dyeable Polyester to produce differentiated and value-added fabrics A growing market for Recycled Polyester Staple Fiber driven by sustainability policies and EU export requirements Our product range matched these preferences closely, allowing the customer to achieve high-efficiency production with consistent fiber performance. Customer Feedback The Turkish client expressed strong satisfaction with both product quality and supply reliability: Dope-dyed black fiber showed excellent color depth and consistency Fiber uniformity significantly reduced yarn breakage Blending performance was stable across polyester–cotton and polyester–viscose yarns Timely shipment ensured uninterrupted production schedules Cost-performance ratio was superior to other regional suppliers The customer highlighted that the 1.2D × 38MM DDB AAA grade performed exceptionally well in their fine-count yarn production, while TOW 3D and TOW 6D DDB were ideal for nonwoven and technical textile lines. Results After incorporating our Polyester Staple Fiber and Polyester Tow into their production: Yarn quality improved by more than 12% based on their internal quality assessment Production efficiency increased due to fewer machine stoppages The durability and consistency of the dope-dyed fiber enhanced color fastness in finished fabrics The customer placed multiple repeat orders and is exploring long-term supply agreements This cooperation strengthened our presence in the Turkish market and demonstrated our capability to offer reliable solutions for Virgin Polyester Staple Fiber, Recycled Polyester Staple Fiber, and Easy Cationic Dyeable Polyester. Conclusion This case highlights how understanding Turkish market needs—color stability, product consistency, and sustainable material options—combined with dependable supply can establish strong, long-term partnerships. We remain committed to supporting Turkey’s textile industry with stable, high-quality Polyester Tow and Polyester Staple Fiber solutions for spinning, knitting, weaving, and nonwoven applications.

Estrutura molecular: Ambos são poliésteres modificados, mas têm composições monoméricas diferentes. Cationic dyeable polyester is usually a ternary copolymer obtained by adding a third monomer (such as sodium dimethyl isophthalate - 5 - sulfonate) during the polycondensation of polyethylene terephthalateO ECDP é um copolímero quaternário, que é obtido pela adição de um quarto monómero (como o polietileno glicol, o isoftalato de dimetil, o ácido adipico, o ácido 1,4-butanedióico, etc.).) à base do copolimero ternárioA introdução do quarto monómero no ECDP altera a estrutura da cadeia molecular, tornando-a mais propícia à tingimento catiônica. Condições de tingimento: O poliéster catiónico tingível necessita, em geral, de ser tingido a uma temperatura de cerca de 120°C ou sob pressão.a cerca de 100°CIsto ocorre porque a estrutura molecular do ECDP é mais aberta e solta, e as moléculas de corante são mais fáceis de penetrar na fibra,para que possa obter bons resultados de tingimento a uma temperatura e pressão mais baixas. Efeito de tingimentoNo entanto, devido à estrutura molecular especial do ECDP, ele tem uma taxa de absorção de cores mais alta e pode mostrar cores mais vivas e profundas.Ao mesmo tempo, a resistência à coloração do ECDP também é relativamente boa e pode manter cores brilhantes após várias lavagens e usos. Processo de produção: A produção de poliéster catiónico tingido requer apenas a adição de um terceiro monómero no processo de polimerização.Enquanto a produção de ECDP requer a adição de um quarto monómero à base do terceiro monómeroPor exemplo, na produção de ECDP, a selecção e a dosagem do quarto monómero, bem como a temperatura de reacção,tempo e outros parâmetros, devem ser rigorosamente controlados para assegurar o desempenho do produto. Desempenho e aplicação: Para além do desempenho de tingimento, o ECDP possui outras excelentes propriedades, por exemplo, melhor higroscopicidade e propriedades antistáticas,e o tecido feito com ele é mais confortável de usarEstas propriedades fazem com que o ECDP seja mais amplamente utilizado na indústria têxtil, especialmente na produção de vestuário de alta qualidade, têxteis domésticos e outros produtos.O poliéster catiônico tingido também é amplamente utilizado, mas em alguns domínios onde são necessários requisitos de tingimento e conforto mais elevados, o ECDP tem mais vantagens.
