Jin Ammonia Heavy Warp Plain Weave Fabric

How can the Jinxiang Heavy Warp Plain Fabric Manufacturer optimize the spinning process to ensure the stable and uniform yarn quality of the Jinxiang Heavy Warp Plain Fabric fabric, while reducing the breakage rate?

1. Preparation before spinning
Raw material selection and processing
Raw material selection: Select fibers with uniform fiber length, high strength, low curl and uniform color as raw materials. Such fibers help reduce the problems of broken ends and yarn defects during the spinning process.
Raw material pretreatment: Perform necessary pretreatment on the raw materials, such as impurity removal and humidification, to improve the spinnability of the fibers and reduce breakage and damage during the spinning process.
Storage management
Keep the raw material storage environment dry and ventilated, avoid direct sunlight, and prevent the raw materials from mold and deterioration. At the same time, control the appropriate temperature and humidity to avoid the raw material absorbing moisture and affecting the yarn quality.
2. Optimization of spinning process
Equipment selection and adjustment
Equipment selection: Select suitable spinning equipment according to the characteristics of the fiber and the quality requirements of the yarn. Ensure that the equipment performance is stable and can meet the production needs of high-quality yarn.
Parameter adjustment: Adjust the specific parameters of the spinning machine, such as tension, rotation speed, offline tension, etc., to ensure that each parameter is within a reasonable range. This helps to reduce the stretching, twisting and breaking of the yarn during the spinning process.
Process optimization
In the combing process, optimize the configuration and management of the combing elements, reduce the intarsia phenomenon of the top comb and cylinder, and avoid the fiber entering the cotton net in a bundle structure, thereby reducing the chance of breakage in the next process.
Regularly check and reasonably adjust the tension state and wear of the drafting toothed belt and the coil toothed belt to reduce the chance of breakage of the drawing frame.
In the roving process, appropriately reduce the jaw spacing, roller center distance and rear zone drafting multiple to reduce the CV value of the spun yarn, but pay attention to maintaining the synchronous development of the holding force and drafting force to prevent poor drafting.
Operation management
Strengthen worker operation training to ensure that workers master the correct use and operation skills of spinning equipment.
Strictly implement spinning quality control standards to ensure that the quality of each batch of products meets the requirements.
Strengthen the management and cleaning of the production site to reduce unfavorable factors such as unclean flying flowers attached to the yarn.
3. Quality control after spinning
Yarn testing
Strictly test the spun yarn, including strength, elongation, color difference, insect eyes, scabs and other problems. Record the test results of each batch of yarn so that problems can be found and adjusted in time.
Subsequent processing guarantee
In the subsequent processing such as printing and dyeing, select high-quality dyes and auxiliaries, and adopt reasonable dyeing technology to ensure that the dryness, cleanliness and quality of the yarn are not affected.

In the finishing processes such as shaping and calendering, how can the supplier of heavy warp plain fabric avoid creases, deformation and other problems of heavy warp plain fabric?
1. Preventive measures in the shaping process
Reasonably set the shaping temperature
The shaping temperature is a key factor affecting the quality of heat setting. For heavy warp plain fabric, the shaping temperature should be reasonably set according to the elastic shrinkage and thickness of the fabric. Usually, the heat setting temperature of spandex knitted fabric can be controlled between 180-195℃, but the specific temperature needs to be adjusted according to the actual situation of the fabric.
It should be noted that too high temperature may cause the fabric to turn yellow and lose elasticity, while too low temperature may not achieve the ideal shaping effect.
Control the shaping time and speed
The length of the shaping time and the speed of the machine will also affect the shaping effect. The speed should be reasonably set according to the length and temperature of the shaping machine to ensure that the fabric has enough time for heat setting in the heating zone.
Too fast speed may affect the shaping effect, resulting in the inability to completely eliminate fine wrinkles; too slow speed and too high temperature may cause the fabric to turn yellow.
Adjust overfeed and tension
During the setting process, the control of overfeed and tension is also crucial. Excessive overfeed may cause unevenness of the fabric surface and difficulty in eliminating fine wrinkles; while excessive tension may cause curling of the fabric during heat setting.
Therefore, the overfeed and tension should be reasonably set according to the fabric characteristics and equipment performance to ensure that the fabric remains flat during the setting process.
Regularly check and maintain equipment
The status of the setting machine equipment has a great influence on the setting effect. The heating system, transmission system, and cloth guide wheel and other components of the equipment should be checked regularly to ensure that they are in good condition.
Problems found should be dealt with in a timely manner to avoid creases or deformation of the fabric due to equipment failure.
2. Preventive measures in the calendering process
Choose a suitable calendering process
The choice of calendering process should be determined according to the fabric characteristics and customer needs. For gold ammonia heavy warp plain fabric, tension-free or low-tension calendering process can be used to reduce the impact on the elasticity and recovery performance of the fabric.
Control calendering temperature and pressure
Calendering temperature and pressure are important factors affecting the calendering effect. The temperature and pressure parameters should be set reasonably according to the characteristics of the fabric and the performance of the calender.
Too high temperature or too high pressure may cause the fabric to turn yellow, the indentation to be too deep or to deform; while too low temperature or too low pressure may not achieve the ideal calendering effect.
Keep the fabric surface flat
During the calendering process, the fabric surface should be kept flat. This can be achieved by adjusting the position and tension of the guide wheel. At the same time, the fabric surface should be prevented from being stretched or squeezed unnecessarily during the calendering process.
