What factors affect the softening effect of the normal temperature roller dyeing machine?
Dec 02, 2024
1. Selection of softener
Softener type: Different types of softeners have different softening effects. Cationic softeners have better softening effects, but may reduce the whiteness of the fabric; non-ionic softeners have less effect on the whiteness of the fabric, but the softening effect is relatively weak; anionic softeners are usually used in combination with other types of softeners. For example, for white pure cotton fabrics, non-ionic softeners can be selected to avoid the impact on whiteness; while for dark chemical fiber fabrics, cationic softeners can be selected to obtain better softening effects.
Softener quality: The quality of the softener directly affects the softening effect. High-quality softeners have good stability, permeability and washability, and can form a uniform soft film on the surface of the fabric, giving the fabric a lasting soft effect. Softeners of poor quality may have problems such as precipitation, stratification, and yellowing, which affect the softening effect and the quality of the fabric. Therefore, when choosing a softener, you should choose a brand product with reliable quality and good reputation.
Softener concentration: The concentration of the softener also has a great influence on the softening effect. Generally speaking, the higher the concentration of softener, the better the softening effect, but too high a concentration may cause problems such as greasy feel of the fabric and decreased hygroscopicity. On the contrary, too low a concentration may not achieve the expected softening effect. Therefore, it is necessary to reasonably adjust the concentration of softener according to factors such as fabric material, thickness, color, etc. Under normal circumstances, the concentration of softener is more suitable between 1-5%.
2. Process parameters
Temperature: The softening treatment of the normal temperature roller dyeing machine is usually carried out at room temperature, but a slight change in temperature will also have a certain effect on the softening effect. Generally speaking, an increase in temperature can increase the permeability and diffusion rate of the softener, thereby enhancing the softening effect. However, too high a temperature may cause the softener to decompose, volatilize or react adversely with the fabric, affecting the softening effect and the quality of the fabric. Therefore, during the softening process, the temperature should be controlled to avoid being too high or too low. Generally speaking, the softening treatment temperature of the normal temperature roller dyeing machine is more suitable between 20-30℃.
Time: The time of the softening treatment is also one of the important factors affecting the softening effect. If the time is too short, the softener may not fully penetrate into the fabric, resulting in an unobvious softening effect; if the time is too long, although the softening effect can be improved, the production cost and production cycle will increase. Therefore, it is necessary to reasonably determine the softening treatment time according to factors such as the material, thickness, and concentration of the softener of the fabric. Generally speaking, the softening treatment time is more appropriate between 20 and 60 minutes.
Bath ratio: The bath ratio refers to the weight ratio of the fabric to the softener solution. The size of the bath ratio will affect the adsorption amount and distribution uniformity of the softener on the fabric, thereby affecting the effect of the softening treatment. Generally speaking, if the bath ratio is too small, the softener concentration is relatively high, which is easy to cause the softener to accumulate on the surface of the fabric, affecting the feel and hygroscopicity of the fabric; if the bath ratio is too large, the softener concentration is relatively low, and the expected softening effect may not be achieved. Therefore, it is necessary to reasonably determine the bath ratio according to factors such as the material, thickness, and concentration of the softener of the fabric. Generally speaking, the bath ratio is more appropriate between 1:5 and 1:20.
Speed: The speed refers to the running speed of the fabric in the normal temperature roller dyeing machine. The speed of the vehicle will affect the contact time and intensity of the softener and fabric, thus affecting the softening effect. Generally speaking, if the speed is too slow, the softener and fabric will have a longer contact time and a better softening effect, but it will reduce production efficiency; if the speed is too fast, the softener and fabric will have a shorter contact time and may not achieve the expected softening effect. Therefore, it is necessary to reasonably adjust the vehicle speed according to factors such as the material, thickness, and concentration of the softener of the fabric. Generally speaking, the speed is more suitable between 5 and 30 meters per minute.
3. Fabric characteristics
Fabric material: Fabrics of different materials have great differences in their adsorption capacity and softening effect on softeners. Generally speaking, natural fiber fabrics (such as cotton, linen, silk, wool, etc.) are easier to absorb softeners than synthetic fiber fabrics (such as polyester, nylon, acrylic, etc.), and the softening effect is also better. This is because the surface of natural fiber fabrics has more hydrophilic groups, which can form a strong binding force with softener molecules. The surface of synthetic fiber fabrics is usually smoother, less hydrophilic, and has a weaker adsorption capacity for softeners. Therefore, when softening fabrics of different materials, it is necessary to select appropriate softeners and process parameters to achieve the best softening effect.
Fabric thickness: The thickness of the fabric will also affect the effect of the softening treatment. Generally speaking, thicker fabrics require longer softening treatment time and higher softener concentration to achieve better softening effect. This is because the gaps between the fibers inside thicker fabrics are larger, and the softener needs more time and concentration to fully penetrate into the fabric. On the contrary, thinner fabrics require shorter softening treatment time and lower softener concentration to avoid the accumulation of softener on the fabric surface, affecting the feel and hygroscopicity of the fabric.
Fabric color: The color of the fabric will also have a certain effect on the effect of the softening treatment. Generally speaking, dark fabrics are easier to absorb softeners than light fabrics, and the softening effect is better. This is because the surface of dark fabrics is usually rougher, has better hydrophilicity, and can form a stronger binding force with softener molecules. The surface of light-colored fabrics is usually smoother, has poor hydrophilicity, and has weaker adsorption capacity for softeners. Therefore, when softening fabrics of different colors, it is necessary to adjust the concentration of the softener and the process parameters according to the color of the fabric to achieve the best softening effect.
