SYLIC TEXTILE AUXILIARIES

Principles and applications of various leveling agentsLeveling agents should have the following features: enabling the dye to be slowly adsorbed by the fiber (having a slow dyeing effect); if the dyeing is uneven, the dye can be moved from the dark part to the light part (having a transfer effect);

What is the color-fixing principle of acidic color-fixing agent‌? ‌Ionic bonding‌: The acidic fixative forms an ionic bond through its cationic group and the anionic group in the dye, blocking the water-soluble group of the dye to form an insoluble lake, which is deposited on the fiber, thereby impr

The principle and process of dispersing agentDispersants are surfactants with two opposite properties, lipophilicity and hydrophilicity, in their molecules. They can evenly disperse the solid and liquid particles of inorganic and organic pigments that are difficult to dissolve in liquids, and at the

What are the functions of scouring agents in dyeing and finishing? Remove fiber impurities: In the production process of textiles, some impurities such as grease, wax, pectin, etc. are often attached to the fiber surface. These impurities not only affect the penetration of dyes, but also may cause

Dye production is generally divided into three steps:1. Synthesis of dye intermediates2.dye intermediate by chemical reaction to produce dye powder3.the dye powder is processed to produce commercial dyes, that is, the commercialization of dyes First. Dispersant:Should be the most used additives in t

1、The effect of softener1, supplement natural fiber in refining, bleaching and other processes lost natural oil, so that the feel is more ideal.2, attached to natural fibers or synthetic fibers, improve smoothness and strength, improve feel.3, through the softener has some characteristics, improve t

Adhesives play a crucial role in the textile industry, contributing to the creation of various high-quality and functional textile products. They are employed in multiple stages and processes to achieve specific results.One of the common applications of adhesives is in the lamination of textiles. Th

High hydrogen silicone oilHydrogenated silicone oil is a key product among silicone oil varieties. It is not only the starting material for many modified silicone oils, but also can be used to obtain a variety of modified silicone oils through silane addition reaction, such as polyether modified sil

1. Solidez a la luzLa solidez a la luz se refiere al grado en que los tejidos de colores se decoloran por la luz solar. El método de prueba puede ser la exposición al sol o la máquina de exposición al sol. El grado de decoloración de la muestra después de la exposición se compara con la muestra de c

A wetting agent is a surfactant that can reduce the surface tension or interfacial tension of a solid, allowing water to spread on or penetrate the surface of the solid, thereby wetting the solid.In the dyeing and finishing process of textiles, wetting agents can reduce the surface tension or interf

In the textile industry, the development and application of water repellents have always been an important aspect to improve the functionality and performance of textiles. Fluorine-free water repellents have emerged as a promising alternative in recent years, offering significant benefits without th

En la actualidad, la impresión con pigmentos requiere el poder formador de película de un aglutinante para fijar los pigmentos que son insolubles en agua y no tienen afinidad ni reactividad con el tejido mediante la acción de un agente reticulante para lograr el propósito de la impresión. La impresi

The properties that color fixers should have:1. Strong color fixation ability, which can significantly improve the color fastness index of dyed or printed textiles; 2. The dye has wide adaptability, and the dye structure has little effect on the color fixation effect; 3. Strong affinity with fibers,

1.Common quality problems in softening finishing:① Failure to achieve the desired feel:The soft style of softening finishing varies with customer requirements, such as soft, smooth, fluffy, soft and sticky, oily, dry and smooth, etc. Different softeners are selected according to different styles. Fo

1 Problema alcalinoEl pretratamiento de las telas de algodón suele necesitar un tratamiento con una concentración más alta de álcali para eliminar las impurezas de la tela (especialmente con una mayor cantidad de álcali mercerizante). No es fácil lavar el álcali en la fibra. Al teñir (colorantes rea

¿Cuál es el papel del agente fijador? El agente fijador en los auxiliares de impresión y teñido se refiere a los auxiliares añadidos antes o después de teñir la fibra con el tinte para mejorar la solidez del color. El tinte todavía se puede teñir sin él, pero la solidez del color es pobre. . Por lo

1. What is block silicone oil?Block silicone oil is a synthetic silicone polymer composed of three main parts: siloxane segments, hydrophobic segments and hydrophilic segments, forming a specific block structure. The hydrophobic segment is usually composed of hydrocarbon chains or siloxane chains, w

Hay dos métodos principales de impresión y teñido de tejidos: uno es la impresión y el teñido con pintura tradicional y el otro es la impresión y el teñido reactivos, en contraposición a la impresión y el teñido con pintura.La impresión y el teñido reactivos consisten en que, en determinadas condici

With the continuous progress of the automotive industry and the improvement of consumer requirements for vehicle performance, automotive sealant as an important material to ensure the tightness of the car and prevent oil leakage and air leakage, its performance improvement is particularly important.

Inorganic thickenersInorganic thickeners include inorganic salt thickeners and inorganic gel mineral thickeners. Inorganic salt thickeners mainly include sodium chloride, potassium chloride, ammonium chloride, etc. When surfactants form micelles in aqueous solution, the presence of such electrolytes
