Textile machinery accessories are mainly used in textile machinery and play a key role in various aspects of textile production.
1、 Spinning process
1. Lola
Stretching function: Roller is an important accessory used for stretching fibers in spinning machines. In equipment such as roving machines and spinning machines, the roller gradually stretches and refines the fiber strands by gripping and rotating them. For example, in a ring spinning machine, the front roller, middle roller, and rear roller operate at different speeds, causing the fiber strands to be stretched between them, resulting in parallel arrangement of fibers and achieving the desired yarn fineness.
Ensure yarn quality: The surface quality and accuracy of the roller have a significant impact on yarn quality. A roller with a smooth surface and high precision can evenly grip and stretch fibers, reduce defects such as coarse and fine knots and cotton knots in the yarn, and improve the uniformity and strength of the yarn.
2. Ingot
Twisting function: The spindle is a key component that twists the yarn during the spinning process. On the spinning machine, the yarn is wound around the yarn tube at the top of the spindle, and the spindle rotates at high speed to drive the yarn tube to rotate, resulting in the yarn obtaining twist. For example, in ring spinning, the spindle speed can reach around 10000-20000 revolutions per minute. By twisting, the fibers are held together to form a yarn with a certain strength, which meets the requirements of subsequent weaving processes.
Stable yarn forming: The stability of the spindle is crucial for yarn forming. If the spindle vibrates or shakes during rotation, it can cause uneven yarn tension, poor yarn forming, and problems such as loose or tight twisting. Therefore, high-quality spindles can ensure uniform twisting and good shaping of the yarn.
3. Steel collar and wire ring
Yarn winding: On a spinning machine, steel rings and steel wire rings work together to wind yarn. The steel wire ring slides at high speed on the steel collar, guiding the yarn to be evenly wound around the yarn tube. For example, when the spindle drives the yarn tube to rotate, the yarn is guided by the steel wire ring and wrapped layer by layer on the yarn tube under the constraint of the steel collar, forming a regular yarn package.
Affects yarn tension and speed: The weight and shape of the wire loop can affect the tension and winding speed of the yarn. Different yarn varieties and spinning processes require the selection of suitable wire loops to ensure that the yarn has appropriate tension during winding, avoiding breakage and yarn quality degradation.
2、 Weaving process
1. Integrated frame and stop frame
Opening motion: In weaving machines, the warp frame is used to control the opening motion of the warp yarn. The integrated frame moves up and down to form a shuttle opening for the warp yarn, facilitating the introduction of weft yarn. For example, in both shuttle looms and non shuttle looms (such as jet looms, rapier looms, etc.), the motion pattern of the frame determines the organizational structure of the fabric. The warp stop piece is used in conjunction with the warp frame to detect the breakage of the warp yarn. When the warp yarn is broken, the warp stopping piece falls, triggering the warp stopping device of the loom, causing the loom to stop in time and avoiding defective fabric.
Improving weaving efficiency and quality: A good fit between the warp frame and the warp stop can ensure the smooth progress of the weaving process. The correct opening movement can enable the weft yarn to pass smoothly through the shuttle opening and reduce weft defects; Timely breakage detection can reduce weaving defects, improve weaving efficiency and product quality.
2. Reed seat and steel reed
Weaving function: The steel reed is installed on the reed seat. During the weaving process, the reed seat moves forward and backward with the steel reed, pushing the weft yarn introduced into the shuttle mouth towards the weaving mouth, tightly interweaving the weft yarn and warp yarn, forming a fabric. For example, in a jet loom, the beating force and speed of the steel reed have a significant impact on the weft density and appearance quality of the fabric. Appropriate beating force can ensure that the weft yarn is evenly distributed in the fabric, making the fabric tight and flat.
Control fabric weft density: The specifications of the steel reed (such as the number of reed teeth) determine the weft density of the fabric. By selecting steel reeds of different specifications, fabrics with different weft densities can be woven to meet the design requirements of various fabrics.
3、 Printing and dyeing process (some textile machinery also involves pre-treatment before printing and dyeing)
1. Rolling mill
Uniformity of rolling solution: During the pre-treatment and dyeing process of printing and dyeing, rolling mills are used to roll off excess liquid on fabrics. For example, in processes such as desizing, boiling, and bleaching of fabrics, rolling mills can evenly roll the treatment solution into the fabric or remove waste liquid from the fabric. For example, in the continuous rolling dyeing process, the rolling mill can ensure that the dye solution is evenly distributed on the surface of the fabric, making the dyeing uniform and consistent.
Control fabric liquid carrying rate: The pressure and surface condition of the rolling mill will affect the liquid carrying rate of the fabric. The appropriate liquid carrying rate is crucial for the quality and cost control of subsequent dyeing, printing, and other processes, as it directly affects the amount of dye and additives used, as well as the drying efficiency of the fabric.
