The preparation method is characterized by washing waste short fiber flax of a flax textile factory by using water, drying and crushing; processing by using NaOH and OP water solution and drying to obtain degummed flax; adding the following components in percentage by mass in a reactor: 22-40% of epoxy chloropropane, 12-25% of degummed flax, 4-8% of NaOH, 5-10% of isopropyl alcohol and 32-55% of water, wherein the sum of all the components is 100%; stirring at the constant temperature of 55-65 DEG C, carrying out backflow reaction for 1.0-4h, cooling, washing by using de-ionized water, carrying out suction extracting and filtering until the filtrate is neutral, washing by using a small amount of ethanol, drying in a 50-55 DEG C vacuum drying box, so as to obtain the epoxy chloropropane modified flax. The adsorbent has very high adsorbing capacity to basic dye, has high regeneration property, can be used repeatedly for several times, and is low in cost and environment-friendly.

The invention discloses a method for modifying and degumming jute fibers, relating to the technical field of jute spinning. The degumming method comprises the following steps: (1) putting jute in a steamer, submerging all the jute into water, then adding sodium sulfite and a softening agent and steaming the jute at a high temperature being 105-115 DEG C for 6-9 hours; (2) fishing up the jute, washing the jute with clear water cleanly, then dehydrating the jute with a spin dryer and then drying the jute in the sun or drying the jute; (3) sending the jute onto a softening machine and adding linen softening oil and cellulase while beating the jute; (4) stowing the jute to be preserved at 20-30 DEG C for 3-7 days, thus degumming and modifying the jute into linen fabrics. Compared with the prior art, the method has the advantages and positive effects that the softness of the jute is improved and the spinnability of the jute is enhanced, thus solving the problem of scratchiness to the skins; the grade and the added values of the jute products are increased and great social and economic benefits are achieved; the state that the jute fiber resources are only used for extensive spinning for a long time and cannot be effectively utilized in the fields of garments and home textile fabrics is changed.

The invention discloses a nozzle device for flax textile processing equipment, relates to the technical field of textile nozzle devices, and comprises a main pipe, one end of a connecting pipe is fixedly connected to the middle part of the lower surface of the main pipe, and the other end of the connecting pipe runs through the conveying pipe. The upper surface of the pipeline is fixedly installed in the middle of the upper surface of the delivery pipeline, the lower surface of the delivery pipeline is provided with a plurality of openings, one end of the branch pipe is fixedly installed with the opening, and the other end of the branch pipe is fixedly connected with a fastening device The nozzle device of the linen textile processing equipment in the middle part of the upper surface, on the one hand, the main pipeline feeds the prepared dye into the delivery pipeline through the connecting pipe; on the other hand, the delivery pipeline sprays the dye from the nozzle head through the diverter Out, the textile fabric is dyed, and secondly, the nozzle head is evenly distributed in the circumferential direction of the branch pipe, which can make the spraying of the dye more uniform and improve the dyeing efficiency.

The invention discloses a dyeing device for flax textile processing, which comprises a dyeing tank, a spreading board, a sealing cover, a cloth outlet, an installation base and a control box. Beneficial effects: the present invention utilizes the glue removing board provided, and under the interaction of the acid cloth strip and the steam strip, realizes the softening treatment of the fat wax remaining on the surface of the flax, so as to avoid the problem of secondary dyeing of the cloth due to The hydrophobicity of fat wax affects the immediacy and adsorption of dyes, which leads to the aggregation of dye particles at low temperature and concentrated dyeing at high temperature, so as to reduce the fastness of dyeing. In order to avoid the heavy weight of the linen fabric with too much dye solution during the lifting process, the linen fabric runs at a low speed, causing its tension to expand and deform, and at the same time, the linen fabric is continuously changed by shaking State, in order to reduce the phenomenon of creases.
