Description
Technical Field
The invention relates to the technical field of garment processing, in particular to citric acid non-ironing finishing liquid for flax garments and a non-ironing finishing method.
Background
As the linen fabric is used as a natural fiber garment fabric, the linen fabric can absorb 20% of water equivalent to self weight, has high moisture absorption rate and good heat dissipation performance, meets the requirement of people on wearing comfort in summer, but cannot meet the requirement of people on garment smoothness in various occasions because the anti-wrinkle performance of the linen fabric is inferior to that of chemical fibers.
The requirement for keeping the clothes smooth is that the clothes have wrinkle resistance in the wearing process, and can keep good smooth state or pleated and stable form without ironing after washing, namely the function of no-iron of the clothes. At present, the domestic non-ironing technology mainly comprises liquid ammonia finishing, resin treatment and the like. However, due to the danger of the liquid ammonia, the enterprise generally does not adopt the technology any more. In the resin non-ironing treatment, the common finishing agent can generate chemical reaction on the surface of the fabric, and a small amount of formaldehyde can be released when the fabric is worn, so that the pursuit of modern people on health and environmental protection can not be met.

s4, preparation: injecting the non-ironing finishing liquid in the step S3 into a medicine soaking pool, and then soaking the auxiliary medicine soaking tool in the step S2 and the flax ready-made clothes in the step S2 into the medicine soaking pool;
s5, soaking the medicine: starting a control system of the auxiliary medicine soaking tool, and controlling the auxiliary medicine soaking tool through the control system, so that the auxiliary medicine soaking tool repeatedly extrudes flax ready-made clothes stacked in the auxiliary medicine soaking tool at the frequency of 2-3 times per minute, and the flax ready-made clothes are maintained in an extruded and loosened state for 3-5 minutes of medicine soaking time;
s6, squeezing: the flax ready-made clothes and the auxiliary medicine soaking tool which are fully soaked with the non-ironing finishing liquid are lifted out of the medicine soaking pool and are suspended above the medicine soaking pool, a control system of the auxiliary medicine soaking tool is started again, and the flax ready-made clothes stacked in the auxiliary medicine soaking tool are extruded, so that the liquid carrying rate of the flax ready-made clothes is reduced to 40% -50%;
s7, pre-drying and moisture fixing: conveying the stacked ready-made flax clothes in the auxiliary medicine soaking tool into an oven through a conveying device, and heating at 90 ℃ to control the liquid carrying rate of the ready-made flax clothes to be reduced to 15% -20%;
s8, shaping and pressing: flatly paving the flax ready-made clothes processed in the step S7 into a pressing machine piece by piece, and carrying out sizing pressing by adopting the temperature of 170-180 ℃ and the pressure of 3kg/cm, wherein the pressing time is 8-10 seconds, so that the non-ironing finishing liquid and fabric fibers are subjected to partial cross-linking reaction;
s9, baking and shaping: hanging the flax ready-made clothes processed in the step S8, and sending the flax ready-made clothes into a baking forming machine for baking at the temperature of 160-170 ℃ for 2-3 minutes to realize the cross-linking reaction between the non-ironing finishing agent and the fabric fiber and form the flax ready-made clothes;
s10, non-ironing finishing post-treatment: and (4) placing the flax ready-made clothes treated in the step (S9) into a constant temperature and humidity chamber for slow cooling and moisture regain for 4 hours, then placing the flax ready-made clothes into clear water with the water temperature of 30 ℃ for cleaning for a plurality of times, removing unreacted non-ironing finishing liquid, and dehydrating and drying the flax ready-made clothes.
