What is Thermal transfer dye and its application? Thermal transfer dye, also known as dye for diffusion thermal transfer (dye for diffusion thermal transfer), referred to as D2T2, is a kind of thermal recording material. The ribbon containing the sublimation dye is brought into contact with the rece Read More

Polylactic acid (PLA) fiber is made of carbohydrate-rich substances (such as long rice, sugar beet, cassava and other crops and organic waste) fermented into lactic acid with a certain strain, and then cyclized and dimerized by monomeric lactic acid. High-performance lactic acid polymer is prepared Read More

1. ПрямолинейностьS представляет собой прямолинейность красителя по отношению к волокну, которая характеризуется скоростью адсорбции, когда он адсорбируется в течение 30 минут перед добавлением щелочи. 2. Реакционная способностьR представляет собой реакционную способность красителя, которая характер Read More

Since the beginning of this year, everyone will obviously feel that the frequency of tie-dye is getting higher and higher, not only in many big-name items, but also being planted by more and more stars. Although tie-dye is often complained as a rustic design, as long as it is well matched, this ele Read More

What is Soluble dyes and its application?

The advantage is that the color is s Read More

Aunque algunos colorantes pueden teñir colores más brillantes, los colorantes tienen grupos solubles en agua, lo que hace que la solidez del tratamiento húmedo sea deficiente y el fenómeno de decoloración y tinción es grave. No solo la apariencia del textil en sí es vieja, sino que los colorantes que se desprenden causarán manchas. La tinción sobre fibras blancas o de otro color provocará tinción y combinación de colores. Por ejemplo, los colorantes directos y los colorantes ácidos son propensos a estos problemas. Además, aunque los colorantes reactivos pueden formar enlaces covalentes con fibras de celulosa, la presencia de colorantes hidrolizados o un enjabonado insuficiente de colorantes no unidos durante el teñido también reducirá la solidez del tratamiento en húmedo; Los colorantes reactivos que forman enlaces covalentes también pueden descomponerse y romper enlaces en condiciones ácidas o alcalinas, así como problemas como solidez del color insuficiente al cloro, transpiración e Read More

In the ordinary PET polymerization process, adding a small amount of the fourth monomer can produce the normal temperature and pressure dyeable polyester ECDP. This is mainly due to the introduction of polyethylene glycol flexible segments in the PET macromolecular chain, which makes the molecular s Read More

01 Усиление очистки загрязненных объектов от загрязнений и дезактивации Адекватная предварительная обработка, хорошая смачиваемость ткани, большой капиллярный эффект, диффузионная способность молекул красителя к окрашенному материалу может увеличиваться, тем самым увеличивая скорость поглощения крас Read More

Why sizing?In order to increase the abrasion resistance, smoothness and antistatic properties of the warp yarn in weaving, increase its strength and cohesion, and improve its weaveability, sizing processing must be carried out before weaving, also known as sizing (protective warp yarn), especially f Read More

What is Plastic pigments and its application? Plastic pigments are pigments that can change the color of plastic raw materials. There are three main methods for coloring plastic pigments. The first is to use powdered pigments to color directly, the second is to mix with plasticizers, etc. to form a Read More

Fabric density refers to the number of yarns per unit length, which can be divided into warp density and weft density. The unit is root/10cm.The wool knitted fabric has 1000 stitches (horizontal 100, longitudinal 10 or transverse 50 longitudinal 20), select 10 transverse yarns (narrow 20) under pre- Read More
