50D/2 Original Colored Polyester Embroidery Thread: How to Redefine the Eternal Color of Embroidery Art with Technology?

Original liquid coloring technology: why can colors cross the test of time?

At present, the traditional textile industry is facing severe environmental challenges, and the emergence of 150D/2 original liquid colored polyester embroidery thread has brought a disruptive technological revolution. This innovative Dope Dyeing process disperses nano-sized color masterbatch uniformly in the spinning solution during the polymerization stage of polyester fibers, allowing pigment molecules to tightly bond with polyester macromolecules through covalent bonds, fundamentally solving industry pain points such as uneven dyeing and poor color fastness in traditional post dyeing processes. After strict testing by the international authoritative testing agency SGS, the product still has a color retention rate of 98.7% after completing 500 ISO 6330 standard washes, far exceeding the average level of 82% for traditional dyeing lines; In the simulated outdoor environment xenon lamp aging test, the color difference Δ E value after 1000 hours of continuous exposure was less than 1.5 (almost indistinguishable to the naked eye), truly achieving a breakthrough in color durability of "ten years as new".

The environmental benefits of this breakthrough technology are also remarkable. Multiple comparative data with traditional dyeing techniques show that:

Water saving performance: can reduce water consumption by 45 tons per ton of product production process, equivalent to half a year's water consumption of a family of three, with a water saving rate of up to 92%

Energy consumption performance: Due to the elimination of traditional dyeing processes such as high-temperature steaming and washing, the overall energy consumption has been reduced by 68%, and carbon emissions can be reduced by 1.2 tons per 10000 meters of embroidery thread

Emission control: Thoroughly achieve zero discharge of dyeing wastewater, achieve 100% reduction in COD (chemical oxygen demand) emissions, and fully comply with the strictest EU REACH regulations

Chemical use: Reduce the use of dyeing auxiliaries, fixing agents and other chemicals by up to 23 types, fundamentally eliminating the residual risk of harmful substances such as formaldehyde and azo dyes

Engineering grade fiber design: how to balance artistic expression and industrial durability?

Behind the seemingly simple specification parameter of 150D/2, there is actually precise material engineering wisdom. Through computer fluid dynamics simulation optimization, the design of a 150 denier fineness combined with a 2-strand Z-direction twisted parallel structure can perfectly present ultra-fine lines of 0.3mm (equivalent to the thickness of 3 hair strands) at a standard embroidery density of 20-25 needles/centimeter, while ensuring a three-dimensional protrusion height of 1.2mm on the embroidery surface, perfectly balancing the conflicting requirements of delicacy and fullness. Through field emission scanning electron microscopy (FE-SEM) observation, it can be seen that the cross-section of this embroidery thread adopts a patented five leaf irregular structure design, with the angle between each "petal" precisely controlled at 72 °, increasing the glossy reflection area by 30% compared to conventional circular sections, presenting a unique "velvet like glossy layer" of the embroidery, which can produce a charming three-dimensional visual effect under light.

In terms of physical performance, this product has set multiple new industry records:

Wear resistance: Achieved 35000 cycles without damage in Martindale abrasion test, which is 50 times that of traditional silk thread and even exceeds the wear resistance standard of military parachute materials

Fracture strength: The single line fracture strength reaches 1.2kgf (gram force), which is 40% higher than the average of similar products, and can withstand an instantaneous impact tensile force of 5N

Temperature adaptability: Under extreme cold environment of -40 ℃ to high temperature conditions of 150 ℃, its mechanical performance fluctuation rate does not exceed 5%, fully meeting the embroidery needs of special scenarios such as automotive interiors and outdoor equipment

Humidity stability: With a moisture regain rate of only 0.3%, it will not breed mold even after being placed in an environment with a relative humidity of 95% for 30 days, making it particularly suitable for use in tropical regions。
