Description

Technical Field

[0001] The invention relates to the technical field of textile dyeing and finishing, and in particular to an ecological physical dyeing and finishing process for zero-silicon fabrics. Background Art

[0002] As people's quality of life improves, consumers are paying more and more attention to the performance of fabrics in terms of texture, safety and health, green and low carbon. The traditional printing and dyeing process includes complicated processing procedures, such as the following in order: singeing → cold rolling mill (immersion in alkaline oxygen liquid) → stacking → oxygen bleaching → mercerizing → polishing → drying → pre-stretching → dyeing → shaping and softening → calendering → shrinking, a total of 12 processes. The above processes involve high-energy consumption treatment methods such as high temperature, high alkali, and high oxygen; and a large amount of chemicals need to be rolled into or reacted on the fabrics. A large amount of chemicals in the printing and dyeing wastewater need to be treated before being discharged, otherwise it will cause pollution to the environment; in addition, after printing and dyeing using traditional printing and dyeing technology, more chemicals will remain on the fabrics, among which softeners such as silicone oil are the main ingredients. Fabrics treated with softeners such as silicone oil are prone to have an oily touch, and the fabrics have poor hydrophilicity, and these chemicals are not good for the human body.

[0003] Therefore, how to break the inherent traditional technology, reduce the impact on the environment during the processing process, reduce energy consumption, reduce the use of chemicals, make the fabric cleaner, make the feel softer, and maintain the natural texture and environmental protection characteristics of the fabric, is of very important practical significance and is also in line with the concept of ecological sustainable development. Summary of the invention

[0004] In order to solve the above problems, the present application provides an ecological physical dyeing and finishing process for zero-silicon fabrics.

[0005] The embodiment of the present application provides an ecological physical dyeing and finishing process for zero-silicon fabrics, which includes, in order of treatment: singeing alkali oxygen, low-temperature re-boiling, pre-stretching, dyeing, a first physical treatment, pre-setting, a second physical treatment and a third physical treatment, wherein the treatment temperature of the low-temperature re-boiling is less than 90°C, the first physical treatment uses a biological enzyme treatment liquid to polish and soften the target fabric, the second physical treatment uses airflow to beat and soften the target fabric, and the third physical treatment uses steam to shrink and soften the target fabric.

[0006] In some embodiments, the singeing process comprises: first singeing the target fabric on a singeing machine, and then stacking the target fabric at room temperature for 20-24 hours.

[0007] In some embodiments, the additives used in the singeing stage include: caustic soda, hydrogen peroxide, a stabilizer, a refining agent and a dispersing and complexing agent, wherein the stabilizer includes an anionic adsorption type non-silicon chelating agent, the refining agent includes a non-ionic surfactant complex, and the dispersing and complexing agent includes an anionic metal complexing agent.

[0008] In some embodiments, the low-temperature re-boiling includes alkali boiling and water washing in a dye jigger, wherein the processing temperature of the alkali boiling and the water washing is 80°C.

[0009] In some embodiments, the auxiliary agents used in the alkali cooking include caustic soda and a refined emulsifier, and the refined emulsifier includes a mixture of anionic and nonionic surfactants.

[0010] In some embodiments, the pre-stretching includes wet drying on a setting machine, the pre-stretching temperature is 170°C, and the pre-stretching speed is 60m / min; the dyeing adopts a wet short steam dyeing process, the steaming time on the roller dyeing machine is 1min, and the machine speed is 45m / min; the pre-setting is carried out on a setting machine, and the corresponding processing temperature of the pre-setting is 160°C and the machine speed is 50m / min.

[0011] In some embodiments, the first physical treatment includes: firstly performing wet bio-enzyme polishing and softening treatment on the target fabric using the bio-enzyme treatment liquid in a dyeing machine or a liquid softening treatment equipment, and then washing the target fabric with water, wherein the treatment temperature corresponding to the wet bio-enzyme polishing and softening treatment is 50°C, and the treatment temperature corresponding to the washing with water is 80°C.

[0012] In some embodiments, the bio-enzyme treatment solution comprises bio-enzymes, anti-wrinkle agents and acetic acid, the bio-enzymes comprise cellulose bio-enzymes, and the anti-wrinkle agents comprise anionic / non-ionic acrylamide / acrylic acid copolymers.

[0013] In some embodiments, the second physical treatment is performed on an open-width dry airflow softening machine, wherein the second physical treatment corresponds to a treatment temperature of 100° C., an air volume of 60-70%, and a machine speed of 30 m / min.

[0014] In some embodiments, the third physical treatment includes: pressurizing the steam to 0.4-0.6 bar in the drum and performing shrinkage treatment on the target fabric, wherein the steam temperature is 110° C. and the vehicle speed is 50 m / min.

[0015] The technical solution of this application can achieve the following technical effects:

[0016] (1) The technical solution of the present application adopts low-temperature (80°C or below) ultra-short process pre-treatment in the pre-treatment process, which can make the semi-finished product obtained in the pre-treatment stage have a preliminary softening effect while meeting the necessary conditions for printing and dyeing; multiple physical softening processes are adopted in the post-finishing stage, and there is no need to introduce various types of silicone oil softeners traditionally used for softening and finishing, which reduces the energy consumption level in the printing and dyeing process and the demand for chemical auxiliaries, thereby reducing pollution to the environment and realizing ecological clean production;

[0017] (2) The technical solution of the present application solves two contradictory industry problems: hand feel and pilling. In the traditional dyeing and finishing process, it is necessary to introduce a silicone-based or modified softener (also known as a silicone oil softener) to achieve a smooth hand feel. Adding softeners and silicone oil softeners will greatly reduce the pilling level of the fabric. However, by using the technical solution of the present application to treat the fabric without adding softeners, the fabric can achieve a good hand feel while achieving the pilling level of the fabric that meets the requirements of the national standard first-class product, which is better than adding silicone-based or modified softeners.

[0018] (3) The technical solution of the present application solves the problem of hydrophilicity deviation of fabrics after traditional dyeing and finishing. Since most silicone-based softeners with good hand feel have relatively poor hydrophilicity after being added to fabrics, the technical solution of the present application is used to treat the fabric without adding silicone-based or its modified softeners. The finished fabric has a soft hand feel, excellent hydrophilicity (good hygroscopicity), is skin-friendly and comfortable. DETAILED DESCRIPTION

[0019] In order to facilitate the understanding of this specification, this specification will be described in more detail below. However, this specification can be implemented in many different forms without departing from the core spirit of this specification, and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of this specification more thorough and comprehensive.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this specification belongs. The terms used herein in this specification are only for the purpose of describing specific embodiments and are not intended to limit this specification. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0021] The embodiment of the present application provides an ecological physical dyeing and finishing process for zero-silicon fabrics, which includes, in order of treatment: singeing alkali oxygen, low-temperature re-boiling, pre-stretching, dyeing, a first physical treatment, pre-setting, a second physical treatment and a third physical treatment, wherein the treatment temperature of the low-temperature re-boiling is less than or equal to 80°C, the first physical treatment uses a biological enzyme treatment liquid to polish and soften the target fabric, the second physical treatment uses airflow to beat and soften the target fabric, and the third physical treatment uses steam to shrink and soften the target fabric.

[0022] The target fabric can be various types of fabrics, for example, cotton, linen, regenerated cellulose fibers, or blended fabrics thereof, etc. Moreover, the yarn count and density of the target fabric can be selected according to actual conditions, and this application does not limit this.

[0023] It should be understood that the target fabric corresponding to each processing stage in the zero-silicon fabric ecological physical dyeing and finishing process of the embodiment of the present application can be understood as the target fabric obtained after the previous stage of processing, and accordingly, the target fabric obtained after the current stage of processing will enter the next stage for processing. For example, the target fabric targeted by the first physical treatment is the target fabric after dyeing, and the target fabric obtained after the first physical treatment is processed by the target fabric, and then continues to be processed by the second physical treatment step. After the second physical treatment step is completed, the target fabric obtained by the treatment is sent to the third physical treatment stage for processing.

[0024] The zero-silicon fabric eco-physical dyeing and finishing process provided in the embodiment of the present application is an innovative low-carbon, low-chemical short-process eco-dyeing and finishing process. This process has made a breakthrough in the conventional path of adding a large amount of softeners represented by silicon-containing chemicals during the subsequent finishing and setting machine in the existing dyeing and finishing process to meet the hand feel requirements.

[0025] On the one hand, the traditional dyeing and finishing process has a long pre-treatment process (including singeing → cold rolling mill → stacking → oxygen bleaching → mercerizing, etc.), high tension, many rolling points, and high temperature, high alkali, and high oxygen. The disadvantages make it easy to harden the fabric. The zero-silicon fabric ecological physical dyeing and finishing process provided in the embodiment of the present application optimizes the pre-treatment process, shortens the pre-treatment process, and adopts a low-temperature, low-amount chemical treatment method, so that the hardening trend of the fiber fabric can be avoided throughout the process without hardening the fabric. In addition, it can also greatly reduce the energy consumption level in the printing and dyeing process, and reduce the demand for chemical auxiliaries.

[0026] On the other hand, the zero-silicon fabric ecological physical dyeing and finishing process provided by the embodiment of the present application adopts physical finishing methods in the post-finishing process, and is a multi-effect multi-pass physical finishing. The whole process does not use various types of silicone oil softeners for traditional softening finishing, making the traditional ultra-soft finishing process that cannot use softeners possible, and can achieve low-carbon ecological environmental protection in the true sense. First, in the first physical treatment process, by subjecting the target fabric to a biological enzyme wet clean and soft treatment at low temperature (the process includes polishing and softening treatment, and the treatment temperature is less than or equal to 80°C), the surface finish and pilling performance of the fabric can be improved, and the softness of the semi-finished product can be increased; then, the second physical treatment uses airflow to pat and soften the target fabric, which can make the fabric release the accumulated kinetic energy under continuous impact, thereby achieving a soft and fluffy effect; then, the third physical treatment uses steam to shrink and relax the target fabric to reduce the internal stress of the fabric and ensure the flatness of the fabric. The fabric obtained by the above-mentioned finishing method has a softer feel, is soft and not greasy, is skin-friendly and comfortable, and exhibits good moisture absorption.

[0027] In some embodiments, the alkaline oxygen singeing process comprises: firstly singeing the target fabric on a singeing machine, and then stacking the target fabric at room temperature for 20-24 hours.

[0028] In the traditional dyeing and finishing process, the basic process is singeing (performed in a singeing machine) → immersion in alkali oxygen solution (performed in a cold rolling mill) → stacking at room temperature. In the embodiment of the present application, the above process is simplified as: singeing alkali oxygen (directly feeding and immersion after singeing, without the need for singeing in a singeing machine and then immersion in alkali oxygen solution in a cold rolling mill) → stacking at room temperature, which is a shorter process and more efficient; and the above stacking process does not use steam and can be carried out at room temperature, which can reduce the energy consumption demand of the operation process.

[0029] In some embodiments, the additives used in the singeing stage include: caustic soda, hydrogen peroxide, a stabilizer, a refining agent and a dispersing and complexing agent, wherein the stabilizer includes an anionic adsorption type non-silicon chelating agent, the refining agent includes a non-ionic surfactant complex, and the dispersing and complexing agent includes an anionic metal complexing agent.

[0030] The caustic soda (liquid caustic soda) used in the singeing stage in the embodiment of the present application can be the light caustic soda recovered from the mercerizing machine in the traditional printing and dyeing process. Among them, the stabilizer can be selected from anionic adsorption type non-silicon type chelating agent, the refining agent can be selected from non-ionic surfactant complex, and the dispersing complexing agent can be selected from anionic metal complexing agent.

[0031] In some embodiments, low-temperature re-boiling includes alkali boiling and water washing in a dyeing machine, wherein the treatment temperature of alkali boiling and water washing is 80° C. Specifically, the treatment process conditions of the low-temperature re-boiling step may include: alkali boiling at a temperature of 80° C. and a machine speed of 50 m / min for 10 passes; and then water washing in 80° C. hot water for 6 passes.

[0032] Compared with the traditional dyeing and finishing process (which requires a conventional scouring temperature of above 95°C), the low-temperature re-boiling provided in the embodiment of the present application reduces the scouring temperature to 80°C, and only requires alkali boiling and water washing, which can not only achieve low-temperature treatment and save energy, but also reduce the re-bleaching process and shorten the pre-treatment process.

[0033] In some embodiments, the auxiliary agents used in alkali cooking include caustic soda and a refined emulsifier, and the refined emulsifier includes a mixture of anionic and nonionic surfactants.

[0034] The caustic soda used in the low-temperature re-boiling stage in the embodiment of the present application can also be the diluted caustic soda recovered from the mercerizing machine in the traditional printing and dyeing process. In addition, the refined emulsifier can be selected from at least one of anionic surfactants and nonionic surfactants.

[0035] In some embodiments, pre-stretching includes wet drying on a setting machine, the pre-stretching temperature is 170°C, and the pre-stretching speed is 60m / min; dyeing adopts a wet short steam dyeing process, the steaming time on the roller dyeing machine is 1min, and the machine speed is 45m / min; pre-setting is carried out on the setting machine, and the corresponding processing temperature of the pre-setting is 160°C, and the machine speed is 50m / min.

[0036] In some embodiments, the first physical treatment includes: firstly performing a wet bio-enzyme wet-state softening treatment on the target fabric using a bio-enzyme treatment liquid in a dyeing machine or a liquid softening treatment equipment, and then washing the target fabric with water, wherein the treatment temperature corresponding to the wet bio-enzyme wet-state softening treatment is 50°C, and the treatment temperature corresponding to the washing with water is 80°C.

[0037] The first physical treatment in the embodiment of the present application can be performed by using a dedicated dyeing machine or liquid softening treatment equipment for bio-enzyme cleaning and softening treatment, and then combined with water washing to remove residual chemicals from the pre-treatment. Specifically, intermittent bio-enzyme treatment can be performed on a dyeing machine or liquid softening treatment equipment. During the treatment process, the target fabric is moved back and forth in the treatment liquid, and then washed and dried in a flat width. The above treatment method can improve the smoothness and pilling of the fabric surface (pilling ≥ 3-4 levels) while ensuring the strength of the fabric, and at the same time increase the softness or feel of the semi-finished product.

[0038] In some embodiments, the bioenzyme treatment solution includes bioenzymes, anti-wrinkle agents and acetic acid. The bioenzymes include cellulose bioenzymes, for example, β-1,4-glucan-4-glucan hydrolase; the anti-wrinkle agent can be selected from anionic / nonionic acrylamide / acrylic acid copolymers.

[0039] In some embodiments, the second physical treatment is performed on an open-width dry airflow softening machine, wherein the second physical treatment corresponds to a treatment temperature of 100° C., an air volume of 60-70%, and a machine speed of 30 m / min.

[0040] The second physical treatment in the embodiment of the present application can be carried out on a flat-width dry airflow softening machine. By utilizing the physical wind principle, the heated hot air flow is sent to the air spray box, the fabric is sucked in, the fabric is rubbed, and hit against the grid plate for moderate beating and back and forth movement. The fabric releases the accumulated kinetic energy under continuous impact, thereby achieving a soft and fluffy effect.

[0041] The embodiment of the present application adopts a bio-enzyme polishing process and a soft cleaning process in the first physical treatment stage, and continuously performs dry airflow softening equipment treatment in the second physical treatment stage to soften the fabric body. It can achieve a fluffy and soft feel from fiber to fabric without adding a silicone-based softener.

[0042] In some embodiments, the third physical treatment includes: pressurizing the steam to 0.4-0.6 bar in the drum and performing shrinkage treatment on the target fabric, wherein the steam temperature is 110° C. and the vehicle speed is 50 m / min.

[0043] The following are specific preparation examples involved in the above content of the present disclosure. It should be clear that the following examples are only for illustrating the zero-silicon fabric ecological physical dyeing and finishing process disclosed above, and the specific implementation methods and parameters used therein are only one or several methods in accordance with the many processes and methods described above. Those skilled in the art can use other parameters according to the content introduced in this specification to prepare zero-silicon ecological fabrics according to the above method without deviating from the core spirit disclosed in the application.
