It solves the problem that the traditional boiling and bleaching impurities are easy to block the circulation hole of the yarn rod and deposit in the yarn, resulting in incomplete cooking and bleaching.

Description

A fully automatic boiling and bleaching system for flax yarn

technical field

The invention relates to the field of flax spinning equipment, in particular to an automatic boiling and bleaching system for flax yarn.

Background technique

Flax is one of the earliest natural textile fibers discovered and used by humans, and is an important raw material in linen. Flax is an annual herb that belongs to the bundle of bast fibers. Linen fabric is called "fiber queen" because of its fast moisture absorption, good air permeability, fast heat dissipation, antibacterial, and no static electricity. Because the flax roving contains more colloidal components, the degree of fiber separation is poor and the spinnability is poor. In order to improve its spinnability, the roving is often chemically scoured in production to remove part of pectin, hemicellulose, lignin and other colloids, so that the fiber bundles in the roving are split into finer fibers, thereby improving the fiber's elasticity. The degree of splitting can be processed into high-count yarn and high-grade products. Therefore, hemp fibers such as ramie and flax must be blanched in a blanching pot during the degumming process, so that the non-cellulose substances in the hemp fibers undergo complex processes such as dissolution, cracking, saponification, and emulsification during the scouring process. Removed by chemical reaction, so as to remove glue impurities such as pectin, hemicellulose and lignin in cellulose companions.

The flax bleaching process currently mainly includes chemical bleaching and biological enzyme bleaching. The main process route of chemical bleaching is: water washing-pickling-scouring-water washing-oxygen bleaching-water washing. The main process route of biological enzyme bleaching is: pickling - Washing - Pectinase - Washing - Oxygen bleaching - Washing. The purpose of flax bleaching is to remove the husk, pectin, and attachments, and at the same time destroy the pigment of the flax itself to obtain the required yarn color, and finally obtain a roving with high spinnability. At present, a blanching pot is generally used for blanching flax rovings. CN 202139334 U discloses a blanching pot for basting hemp fibers, which includes a pot body, a pot cover, a hemp hanger and a circulation pump. There is a support plate with a liquid hole, a liquid pipe is arranged at the bottom of the pot body, and a guide cone is arranged at the upper end of the liquid pipe. The hollow column is connected, the lower end of the liquid pipe is connected with one port of the circulation pump through the first pipeline, and the other port of the circulation pump is connected with the bottom cavity of the pot body through the second pipeline. CN 205133791 U discloses a novel full-automatic blanching pot, which includes a flip cover, a heating rod, a rotating mechanism, a hook, a pot body, a motor, a water release switch, a bracket, a temperature sensor, a pH value sensor, a hinge and a water injection port. The lower end of the body is fixed and supported by a bracket, the upper end of the pot body is connected to the flip cover through a hinge, a temperature sensor and a pH value sensor are installed on the inner wall of the pot body, the temperature sensor is located at the lower end of the pH value sensor, and the lower end of the pot body is connected to a water discharge switch. A motor is installed at the bottom of the pot body, the upper end of the motor is connected to a rotating mechanism and is located inside the pot body, a heating rod is arranged inside the rotating mechanism, the hook is arranged on the horizontal mechanism of the rotating mechanism, and the water injection port is arranged at the upper end of the flip cover .

When the above-mentioned blanching pot is blanching, place the hanging hemp hanger with hemp fibers in the pot body, and inject the scouring liquid and water into the pot to submerge the hemp fibers, cover the pot, and feed steam. And start the circulating pump, so that the bleaching liquid and water enter the bottom cavity of the pot body from the upper cavity of the pot body through the liquid hole on the support plate, and then return to the upper cavity of the pot body from the bottom cavity through the pipeline and the circulation pump. It solves the problems of uneven blanching and uncontrollable temperature in the traditional method, and improves the efficiency and quality of blanching. However, there are still some problems. Because the flax yarn is wound in the roving tube and has a certain thickness, the roving is tightly wound, which forms a large resistance to the bleaching liquid entering the yarn, resulting in poor circulation of the boiling liquid. , the problem of uneven blanching and blanching will inevitably occur, which will affect the blanching effect. In order to completely remove impurities and fade the rovings wound on the inside and outside, the traditional scouring and bleaching process either needs to increase the concentration of the solution, or prolong the scouring and bleaching time, or require multiple scouring and bleaching. The chemical scouring process uses a large amount of alkali and oxidant, and the scouring needs to be carried out at high temperature (above 90°C), so no matter which method is used, there will inevitably be large water consumption, high energy consumption, and energy consumption. The big problem is that improper control will damage the flax roving, increase the loss rate of the roving, and cause the quality of the spun yarn to decrease. Moreover, a large amount of waste water required after acid and alkali treatment needs to be treated and discharged, which increases the production cost. As people pay more and more attention to sustainable development, green processing in the textile industry has also attracted more and more attention. Therefore, this problem has become a difficult problem restricting the industrialization efficiency of the hemp spinning industry.
