Device for improving spun yarn performance through on-line controllable application of auxiliary agents in spinning

Abstract

The invention belongs to the technical field of ring spinning, and relates to a device for improving spun yarn performance through on-line controllable application of auxiliary agents in spinning. Thedevice comprises a solution supply system, a solution supply pump, a connecting pipe, a solution feeding casing, a yarn guide rod, a solution collection tank, a solution recovery system, a filteringdevice and a solution guide pump, wherein the solution supply system is connected with a solution injection hole in the upper surface of the solution feeding casing through the solution supply pump, an auxiliary spinning solution in the solution supply system is injected into the solution feeding casing through the solution injection hole, and pressure of a solution in the solution feeding casingis controlled by adjusting the solution supply pump; the solution feeding casing is in a trapezoidal structure, two ends of the trapezoidal structure are connected with a system fixing device throughconnecting screws respectively, yarn guide rods and a solution level observation port are arranged at the top of the trapezoidal structure, and the solution level position in the solution feeding casing is observed through the solution level observation port. The device can completely replace the traditional sizing process, shorten the process flow, greatly reduce the production cost and accurately control the solution feeding process, and most importantly, high-performance yarns for direct weaving can be obtained.

Description

technical field [0001] The invention belongs to the technical field of ring spinning, and relates to a device for controllably applying auxiliary agents on-line during spinning to improve the performance of spun yarns. Background technique [0002] The traditional ring spinning method has always been an important spinning method accounting for more than 80% of the entire yarn production due to its three advantages: wide range of suitable spinning linear densities, strong adaptability of raw materials, and better yarn quality. However, a major disadvantage of ring spun yarn is that the surface hairiness of the unsized yarn is long and abundant, and the fibers are relatively loose. It is easy to fluff the yarn body, and even the yarn disintegrates and breaks. The harmful hairiness formed will cause the yarn sliver to stick together during the weaving process, resulting in unclear openings, and it is easy to form crosspiece weaving defects, which seriously affects production ef...

Problems solved by technology

[0004] With the continuous development of science and technology, many new methods for improving the performance of ring-spun yarns have emerged in recent years. For example, the Chinese invention patent with the publication number CN105019074A "A wet spinning device and wet spinning process" is listed below A water tank is placed under the drafting roller, and a dripping head is placed above the upper drafting roller, and the slurry or water in the dripping head is dripped out through the control panel to wet the fiber, improve yarn strength and softness and reduce yarn hairiness; open The Chinese invention patent No. CN106702554A "A Ring Spinning Machine with a Wetting Device for Reducing Hairiness" uses liquid water to wet the yarn guide wheel in the spinning section between the front roller nip and the yarn guide hook Wet device to reduce yarn hairiness; French patent application No. FR2817878A1 "A Hairiness Reduction Device for Spinning Frame" proposes a method to reduce the twisting triangular area in the process of hemp spinning, and the front roller nip The method of fully moistening the hemp fiber strands between the guide hook and the yarn guide. The fiber strands contact the ceramic rod immediately after coming out of the nip of the front roller to reduce the twisting triangle area, and then pass through the humidification area composed of the water injection pipe and the water bath roller. , the water in the water injection pipe directly immerses the yarn in the water. After the water falls, it enters the water tank and is recycled. There are water bath rollers in the water tank, and the surface is made of capillary water-absorbing material, which can continue to humidify the yarn. The whole humidification process can be water or water-based. solution, but this process does not give the water-based solution composition and specific yarn performance improvement effect, and this process is aimed at hemp spun yarn, and is not suitable for cotton ring spinning process; the Chinese invention patent application with publication number CN108893896A "a fiber On-line sizing spinning machine and sizing method for spun fiber spun yarn at room temperature” proposed an online sizing method for cellulose fibers. The high-speed rotation of the size guide roller drives the liquid in the sizing tank to adhere to its surface, and the twisted yarn passes through the The guide roller completes the sizing process, but the length of contact between the yarn in the twisting section and the guide roller is always changing during this process, and the amount of size that the yarn in the twisting section contacts cannot be adjusted
