Description
Technical Field
The invention relates to the technical field of fabric finishing, in particular to an alkali steaming type finishing method for removing fabric wrinkles.
Background
The usual method for removing wrinkles from fabrics is the hot ironing process, which is completely unsuitable for animal fur fabrics and other wool and wool fabrics, but instead is a hot steam softening process, which only temporarily wets the cellulose, causing the chains of the cellulose to curl or elongate, changing the crystalline and amorphous regions of the cellulose, and thus restoring the softness and resilience of the fabric.
However, according to a great deal of theoretical knowledge and practical experience, the hot steam softening process is only suitable for slightly wrinkled or hardened fabrics, and for fabric wrinkles formed by long-term pressing under external force, wrinkles can be temporarily removed by soaking with hot steam, and the wrinkles are recovered once dried. The fundamental reason for this is that cellulose is irreversibly changed, and especially in the process of multiple washing or long-term overstocked storage, when the cellulose is dipped in dust, fungi and other various substances, cellulose derivatives with high crystallinity are generated by reaction, which causes the fabric to be stiff and not meet the softness requirement of wool fabric.
The prior finishing technology has little countermeasure for the wrinkle removing process of the wool fabric.
Disclosure of Invention
The invention aims to solve the defects in the prior art and provides an alkali steaming type finishing method for removing fabric wrinkles.
In order to achieve the purpose, the invention adopts the following technical scheme:
an alkali-steaming finishing method for removing fabric wrinkles comprises the following steps:
1) weighing the wool fabric in dry weight, soaking the wool fabric in a finishing agent aqueous solution which accounts for 5-6 times of the dry weight, and soaking for 10-15min at the temperature of minus 10-0 ℃;
2) placing the wool fabric soaked with the finishing agent aqueous solution in a heating steam box with a screen, pouring part of the finishing agent aqueous solution below the screen, placing the wool fabric on the screen, arranging a rotating shaft at the bottom of the screen to enable the screen to be centrifugally thrown off, and communicating a clean water inlet pipe and a hydrogen chloride gas inlet pipe at the top of the side wall of the heating steam box;
sealing the heating steam box, setting the heating temperature at 135-165 ℃, heating the water solution of the finishing agent to generate hot mixed gas of ammonia, water vapor and part of formaldehyde, fumigating the wool fabric, rotating the screen at the speed of 100-300r/min, and steaming for 15-20 min;
3) after steaming, reducing the temperature of the heating steam box to room temperature, introducing hydrogen chloride gas by using a ceramic pressure pump, and closing a hydrogen chloride gas inlet pipe when new white crystal powder is not generated on the surface of the wool fabric;
4) opening the clear water inlet pipe to quickly suck water back into the heating steam box, spraying, eluting and cooling the wool fabric
5) And (4) repeating the steps 2) to 4) for 2-3 times, then adopting a detergent to spray and clean, rinsing with clear water, and finally drying to obtain the wrinkle-free wool fabric.
Preferably, the aqueous finishing agent solution comprises the following components in parts by weight: 100 parts of water, 5-6 parts of hydroxyethyl cellulose, 15 parts of sodium hydroxide, 10 parts of ammonia water, 3 parts of aqueous silica gel, 2-3 parts of dimethylol dihydroxyethyl ethylene urea and 4-5 parts of urea; the preparation process of the finishing agent aqueous solution comprises the following steps: dissolving sodium hydroxide and urea in water in a closed container, adding hydroxyethyl cellulose and aqueous silica gel, stirring at high speed, slowly spraying dimethylol dihydroxyethyl ethylene urea, stirring for 2-3min, slowly dripping ammonia water to obtain finishing agent aqueous solution, and storing in dark place. According to the invention, the wool fabric is subjected to preliminary adsorption swelling through a sodium hydroxide-urea system, hydroxyethyl cellulose and water-based silica gel are adopted to reinforce with cellulose, dimethylol dihydroxyethyl ethylene urea (namely 2D resin) is adopted as a cross-linking agent, the cross-linking agent reacts very slowly under an alkaline condition, and can be dehydrated and cross-linked quickly under an acidic heating condition, so that the cellulose forms a net structure, and the purpose of improving the length and rigidity of a molecular chain is achieved.
Therefore, under the alkaline condition, the crosslinking can be effectively inhibited, and the crosslinking agent 2D resin, hydroxyethyl cellulose and water-based silica gel are permeated into structural pores of the cellulose together through alkaline swelling; ammonia water is easy to generate ammonium ions in the presence of sodium hydroxide, partial sodium ions can be replaced to be combined with hydroxyl groups of cellulose, the alkalinity of the finishing agent aqueous solution infiltrated by the wool fabric is improved, ammonia gas and partial formaldehyde are further released in the reheating process, the formaldehyde promotes the dissolution of each molecular chain, the ammonia gas promotes the cellulose alkalinity, an ammonia water layer is formed on the surface layers of the cellulose and gaps of the cellulose, and in the heating and fumigating process, the high temperature promotes the fiber to be stretched, the multi-aspect effect is realized, each high molecular chain is fully mixed, wound and curled, so that a new composite fiber structure is formed, and the composite fiber structure is high in strength and good in elasticity;
then, after introducing hydrogen chloride, quickly performing neutralization reaction with an ammonia water layer on the surface of the wool fabric to generate ammonium chloride and release heat, and then immediately neutralizing the sodium cellulose salt in the cellulose;
ammonia and hydrogen chloride all very easily dissolve in water, exist a large amount of hydrogen chloride in the box, open the clear water spray tube, then suck the clear water backward in the box immediately, produce the automatic spray effect, can carry out primary cooling and erode the fabric.
Preferably, the specific structure of the heating steam box comprises a box body, a motor bin is arranged at the center of the bottom wall of the box body, a motor fixed on the upper surface of the bottom wall of the box body is arranged in the motor bin, a driving shaft of the motor extends out of a bearing seat at the top of the motor bin, the top end of the driving shaft is fixedly connected to the center of a rotary screen disc, a bevel gear ring is fixedly connected to the position, between the bearing seat and the rotary screen disc, of the driving shaft through a flat key, a driven bevel gear is meshed with an upper gear of the bevel gear ring, a supporting shaft is estimated at one side, away from the driving shaft, of the driven bevel gear, the supporting shaft is fixedly connected to the lower surface of the rotary screen disc through two shaft collars, rollers are further arranged in the middle of the supporting shaft at equal intervals, through holes corresponding to the rollers are formed in the rotary screen;
