Elastic card clothing is generally used in the textile industry for fine carding of fibers such as carding cotton, chemical fibers, wool, silk and hemp. The elastic card clothing for carding fibers includes elastic strip clothing for carding machines, card raising clothing for carding machines, removable flat clothing for carding machines, and elastic clothing for raising finishing such as woven, knitted, or warp-knitted fabric. The elastic card clothing for carding that uses at present mostly adopts and implants the steel needle on cotton and the synthetic base cloth of rubber, has certain problem after implanting the steel needle, and the problem includes: the steel needle rust resistance is poor, the steel needle wear resistance is general, steel needle roughness is poor etc. owing to there is above problem, can cause carding to use elasticity card clothing performance unstable, and the wearing and tearing decline is fast, and the rough damage fibre raw materials in surface, rust stain raw materials etc. to cause the product quality who uses carding card clothing unstable, and make card clothing change cycle accelerate, life greatly reduced. At present, the base cloth synthesized by cotton cloth and rubber is adopted on the basis of the elastic card clothing, and when the surface treatment is carried out on the steel needle, the surface treatment can not be carried out on the elastic card clothing because the problems of poor corrosion resistance, weather resistance, oxidation resistance, acid and alkali resistance and the like exist in the cotton cloth and the rubber.
Chinese patent with patent application No. CN202111567727.4 discloses a method for preparing corrosion-resistant elastic card clothing steel needle and corrosion-resistant elastic card clothing steel needle, which adopts the steps of drawing card clothing steel wire rod, austenitizing and lead bath quenching treatment to obtain the corrosion-resistant elastic card clothing steel needle, and improves the components of the steel needle and the processing technology to obtain the corrosion-resistant elastic card clothing steel needle; there is no disclosure of obtaining an anti-corrosive wear resistant coated elastic card clothing by surface treating the elastic card clothing.
Therefore, it is a main technical problem to be solved to provide a method for surface treatment of an elastic card clothing so that the steel needles implanted into the base fabric of the obtained elastic card clothing have excellent corrosion resistance and abrasion resistance.
Disclosure of Invention
The inventor finds in experiments that the elastic card clothing is subjected to electrolytic polishing by adopting the conductive base fabric, and after the elastic card clothing is subjected to surface treatment by using a specific surface treatment agent, a certain surface treatment layer can be formed on steel needles implanted on the base fabric of the elastic card clothing, and the surface treatment layer belongs to a surface compact film layer, the formed surface treatment layer not only can increase the brightness of the steel needles, but also can increase the wear resistance and corrosion resistance of the steel needles, the inventor finds that the base fabric of the elastic card clothing and the implanted steel needles can be in close contact with each other while solving the problem that the steel needles form the certain surface treatment layer, and the uniformity and compactness of the steel needles forming the surface treatment layer can be influenced when the base fabric and the implanted steel needles cannot be in close contact with each other. The inventor finds that the problem that the conductive layer and the elastic layer in the conductive base fabric can be tightly attached needs to be solved while the uniformity and compactness of the surface treatment layer formed on the surface of the steel needle are solved, and the problem that the tight combination of the base fabric and the implanted steel needle is influenced when the conductive layer and the elastic layer cannot be tightly attached further influences the service cycle time of the elastic card clothing.
In order to solve the above problems, the present invention provides a surface treatment method of an elastic card clothing, comprising the steps of:
s1, cleaning the surface of elastic card clothing;
s2, carrying out surface treatment on the elastic card clothing to obtain a treatment layer;
the base fabric of the elastic card clothing includes an elastic layer.
Further, the surface treatment method of the elastic card clothing comprises the following steps:
s1, performing ion beam sputtering cleaning and activation on the surface of the elastic card clothing by adopting a multi-arc ion sputtering coating machine and a Hall ion source;
s2, adopting a vacuum magnetic filtration cathode arc source, and adopting a target material to carry out surface treatment on the elastic card clothing to obtain a treatment layer;
and S3, cooling the surface of the elastic card clothing.
In the step S1, the working voltage of the Hall ion source is 300-500V, the working current is 0.5-2A, the working air pressure is 1-6 multiplied by 10-4Pa, and the working time is 10-20min.
The S2 target material is selected from one or more of silicon dioxide, titanium nitride, aluminum oxide, tungsten nitride and boron nitride.
And in the S2, the thickness of the processing layer obtained by carrying out surface treatment on the elastic card clothing is 2-5um.
The purchase manufacturer of the multi-arc ion sputtering film plating machine is Foxin vacuum technology company Limited in Foshan city, and the model is FOXIN-PVD multi-arc ion sputtering film plating machine.
The inventor finds that in experiments, when the conventional elastic card clothing is made of rubber, and a multi-arc ion sputtering coating machine is used for surface treatment, volatile substances are released from the rubber during vacuum ion plating to influence ion gasification, so that a surface treatment layer is difficult to obtain on the steel needles of the elastic card clothing.
Further, the surface treatment method of the elastic card clothing comprises the following steps:
s1, cleaning the surface of elastic card clothing;
s2, preprocessing the elastic card clothing;
and S3, treating the surface of the elastic card clothing by adopting a surface treating agent to obtain a treated layer.
Preferably, the step of cleaning the surface of the elastic card clothing in S1 includes: adding industrial cleaning agent into water to prepare cleaning solution to carry out ultrasonic cleaning on the elastic card clothing, wherein the ultrasonic cleaning time is 5-15min; and after the ultrasonic cleaning is finished, soaking and cleaning for 2-3 times by adopting clear water, and cleaning for 5-10min each time.
The mass concentration of the industrial cleaning agent in the cleaning solution is 5%.
The industrial cleaning agent is purchased from Shenzhen Tianyun New Material science and technology Limited company, and the model is the degreasing agent.
In order to reduce the treatment process of a certain concentration of acid solution when the surface of the elastic card clothing is cleaned, the inventor finds in experiments that an industrial cleaning agent is added into water to prepare a cleaning solution to carry out ultrasonic cleaning on the elastic card clothing, and the ultrasonic cleaning time is 5-15min; after ultrasonic cleaning is finished, clean water is adopted for soaking and cleaning for 2-3 times, cleaning is carried out for 5-10min each time, and the degreasing agent with the mass concentration of 5% of the industrial cleaning agent in the cleaning liquid can not only realize the effect of thoroughly cleaning the base cloth of the elastic card clothing, but also realize the effect of removing oil and rust on the surface of the steel needle.
Preferably, the base fabric of the elastic card clothing is a conductive base fabric.
Preferably, the conductive base fabric comprises a conductive layer and an elastic layer.
Preferably, the material of the conductive layer is conductive metal.
Preferably, the conductive metal is selected from one or more of gold, silver, copper, iron, aluminum, and nickel.
Preferably, the conductive layer comprises a woven layer of conductive metal wire.
Further, the diameter of the metal wire in the conductive metal wire braided layer is 0.1-0.6mm.
Further, the diameter of the metal wire in the conductive metal wire braided layer is 0.25-0.4mm.
Further, the conductive metal wire braided layer is a copper wire braided layer.
In order to solve the technical problem that the surface treatment of the elastic card clothing can be carried out in an acidic or alkaline environment, the inventor unexpectedly finds that the conductive base cloth is adopted as the base cloth of the elastic card clothing, and the conductive base cloth is provided with a conductive layer and an elastic layer, wherein the conductive layer is a conductive metal wire woven layer, and the conductive metal wire woven layer is a copper wire woven layer. The diameter of the copper wire in the conductive metal wire braided layer is 0.1-0.5mm, particularly the conductive layer formed by braiding when the diameter of the copper wire in the conductive metal wire braided layer is 0.25-0.4mm, when the conductive metal wire braided layer is used, the conductive layer can play a role in supporting and fixing the steel needle implanted into the elastic base fabric, and the steel needle implanted into the elastic card clothing can be subjected to surface treatment by leading the steel needle to be capable of being electrified by taking the conductive layer as a conductive transmission medium. The inventors have found that an elastic layer can be formed of a material having no resiliency, and when a heat-vulcanized rubber layer is used as the elastic layer, there is a problem that the elastic card clothing is easily corroded when subjected to surface treatment.
Preferably, the elastic layer is made of a thermoplastic elastomer.
Preferably, the thermoplastic elastomer has an elongation at break of 600 to 1100%.
Preferably, the thermoplastic elastomer is selected from one or more of EVA, TPE, TPU, TPVC, TPO, POE.
Further, the thermoplastic elastomer is TPE.
As an illustrative example, the TPE's are available in commercially available models including P1745N, P1750N, P1776, P1840P, P1935, P1957TB, P1960T, P1985NT.
In order to improve the resilience of the elastic card clothing, increase the carding performance of the elastic card clothing when carding the fiber and the requirement of having a certain external force releasing performance when encountering external force, and be suitable for the treatment of various long and short fibers, the inventor finds in experiments that by adopting the thermoplastic elastomer as the elastic layer and adopting the TPE with the elongation at break of 600-1100% to have a proper flexible chain segment length, the elastic card clothing can not only realize a certain insertion and wrapping performance for the implanted steel needle, but also have a certain external force releasing performance when encountering external force, and most importantly, by adopting the TPE with the elongation at break of 700-950%, the corrosion performance of the surface treatment liquid on the elastic card clothing can be resisted when the surface treatment is carried out on the elastic card clothing, a stable structural layer can be provided for the steel needle when the surface treatment is carried out, and the technical problem that the surface treatment can be carried out on the elastic card clothing under the acidic or alkaline environment is solved, but the inventor finds that when the conductive layer and the elastic layer can not be tightly combined, the elastic base cloth and the implanted steel needle cloth can be tightly combined, and the use period of the elastic card clothing can be further influenced.
Preferably, an adhesive layer is disposed between the conductive layer and the elastic layer.
Preferably, the adhesive layer has a thickness of 20-25um.

Further, the adhesive a was purchased from beijing reid you technologies ltd under the type kamulock 478AB.
Further, the purchasing manufacturer of the adhesive b is Meitai adhesive Limited company in Shenzhen City, and the model is Meitai 920.
In order to improve the tight bonding between the conductive layer and the elastic layer and improve the uniformity and compactness of the surface treatment layer formed on the surface of the steel needle, the inventor finds in experiments that the adhesive a and the adhesive b are used cooperatively, and the viscosity of the adhesive a at 25 ℃ is 100-350cps; the viscosity of the adhesive b at 25 ℃ is 60-100cps, and the mass ratio of the adhesive a to the adhesive b is 1: (1.5-3.5), and further, the mass ratio of the adhesive a to the adhesive b is 1: (2-3), the problem of delamination of the conductive layer and the elastic layer, particularly the effect of soaking the conductive layer and the elastic layer by the surface treatment agent when the elastic base fabric is subjected to surface treatment, can be improved, probably because the viscosity of the adhesive at 25 ℃ is 60-350cps, the adhesive can be better applied to the conductive layer or the elastic layer when applied, and the tight bonding between the conductive layer and the elastic layer can be affected when the viscosity of the adhesive is too high or too low.
