Referring to fig. 1 to 4, an embodiment of the present invention provides a cord ironing apparatus 100, where the cord ironing apparatus 100 includes a base 101, a first ironing member 102, and a second ironing member 103. The first ironing member 102 is provided with a first arc-shaped through slot 1021, and the second ironing member 103 is provided with a second arc-shaped through slot 1031. The first ironing piece 102 and/or the second ironing piece 103 are movably connected to the base 101, the first arc-shaped through slot 1021 and the second arc-shaped through slot 1031 can be mutually matched to form an ironing channel for ironing the round rope 200, and the first ironing piece 102 and the second ironing piece 103 can be mutually matched to be used for adjusting the distance between the first arc-shaped through slot 1021 and the second arc-shaped through slot 1031.

When the ironing device in this embodiment is used for ironing the round rope 200, the positions of the first ironing piece 102 and the second ironing piece 103 are adjusted to adjust the first arc through slot 1021 and the second arc through slot 1031 to a proper position, then the round rope 200 is placed in the second arc through slot 1031, and the positions of the first ironing piece 102 and the second ironing piece 103 are continuously adjusted, so that the first arc through slot 1021 and the second arc through slot 1031 form an ironing channel, and at this time, the round rope 200 is positioned in the ironing channel. The ironing parameters between the first ironing press 102 and the second ironing press 103 are set to the proper range, and the round rope 200 is then ironed. When the ironing equipment is used for ironing the round rope 200, the round rope is positioned in the ironing channel, the round rope is not easy to deform in the ironing process, the round shape of the round rope can be effectively maintained, and the processing requirement of ironing the round rope is met. In addition, after the ironing of a certain section of the round rope is finished, the continuous processing of the ironing of the round rope can be realized by adjusting the position of the round rope in the ironing channel, and the processing efficiency is improved.

In a specific example, the first stamping part 102 and/or the second stamping part 103 are stamping plates. Preferably, the first stamping part 102 and the second stamping part 103 are both stamping plates.

In a specific example, the cord ironing device 100 is composed of a base 101, a first ironing press 102 and a second ironing press 103. The first ironing member 102 is provided with a first arc-shaped through slot 1021, and the second ironing member 103 is provided with a second arc-shaped through slot 1031. The first ironing piece 102 and/or the second ironing piece 103 are movably connected to the base 101, the first arc-shaped through slot 1021 and the second arc-shaped through slot 1031 can be mutually matched to form an ironing channel for ironing the round rope 200, and the first ironing piece 102 and the second ironing piece 103 can be mutually matched to be used for adjusting the distance between the first arc-shaped through slot 1021 and the second arc-shaped through slot 1031. The round rope ironing device 100 in the example consists of the base 101, the first ironing piece 102 and the second ironing piece 103, can effectively iron and press the round rope, can effectively keep the round shape of the round rope, meets the processing requirement of ironing and pressing the round rope, can realize continuous processing of ironing and pressing the round rope, and improves the processing efficiency.

As a preferable scheme, the first arc-shaped through groove 1021 is a circular arc-shaped through groove, and the central angle of the circular arc of the radial section of the first arc-shaped through groove 1021 is 178-183 degrees. At this time, the first arc through groove 1021 and the round rope can be well matched, and the stability of the round rope in the ironing process is further improved. The angle is too big, and the round rope atress is uneven, and the too little round rope of angle is difficult to the complete pressfitting, the problem of deformation appears easily at the edge of arc wall. Specifically, the central angle of the circular arc of the radial cross section of the first arc-shaped through groove 1021 may be, but is not limited to, 178 °, 179 °, 180 °, 181 °, 182 °, 183 °, or the like. It is further preferable that an angle other than 180 ° is adopted as a central angle of the circular arc of the radial cross section of the first arc-shaped through slot 1021 in order to make the first arc-shaped through slot 1021 fit with the circular rope better.

Further, the second arc-shaped through groove 1031 is a circular arc-shaped through groove, and the central angle of the circular arc of the radial section of the second arc-shaped through groove 1031 is 178-183 degrees. At this time, the second arc-shaped through groove 1031 and the round rope can be well matched, so that the stability of the round rope in the ironing process is further improved. The angle is too big, and the round rope atress is uneven, and the too little round rope of angle is difficult to the complete pressfitting, the problem of deformation appears easily at the edge of arc wall. Specifically, the central angle of the circular arc of the radial cross section of the second arc-shaped through groove 1031 may be, but is not limited to, 178 °, 179 °, 180 °, 181 °, 182 °, 183 °, or the like.

Further, the central angle of the circular arc of the radial cross section of the first arc-shaped through groove 1021 is equal to the central angle of the circular arc of the radial cross section of the second arc-shaped through groove 1031. At this time, the acting force of the first arc through groove 1021 and the second arc through groove 1031 on the round rope is more uniform, the consistency of the action on the round rope can be improved, and the stability of the round rope in the ironing process is more effectively maintained.

In one specific example, the radial cross-section of the first arcuate slot 1021 has a radius of 1mm to 4mm. In the actual processing process, the diameter of the circular rope is usually smaller, and the radius of the radial section of the first arc-shaped through groove 1021 is set to be 1-4 mm, so that the processing of the conventional circular rope can be met. For example, the radial cross-section of the first arcuate slot 1021 has a radius of 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, 2.5mm, 2.8mm, 3mm, 3.2mm, 3.5mm, 3.8mm, or 4mm.

Corresponding to the first arc-shaped through groove 1021, the radius of the radial section of the second arc-shaped through groove 1031 is 1 mm-4 mm. The radius of the radial section of the second arc-shaped through groove 1031 is set to be 1 mm-4 mm, so that the processing of the conventional round rope can be satisfied. For example, the radial cross-section of the second arcuate channel 1031 has a radius of 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, 2.5mm, 2.8mm, 3mm, 3.2mm, 3.5mm, 3.8mm, or 4mm.

Preferably, the radius of the radial cross section of the first arc-shaped through groove 1021 is equal to the radius of the radial cross section of the second arc-shaped through groove 1031. At this time, in the ironing process, the uniformity of the acting force of the first arc-shaped through groove 1021 and the second arc-shaped through groove 1031 on the round rope can be effectively improved, and the ironing quality of the round rope is further improved.

It should be noted that, the number of the first arc-shaped through grooves 1021 is plural, and the number of the second arc-shaped through grooves 1031 is plural; the first arc-shaped through grooves 1021 and the second arc-shaped through grooves 1031 can be opposite to each other one by one to form a plurality of ironing channels. Through the setting of a plurality of first arc logical grooves 1021 and second arc logical grooves 1031, can scald the pressure to many round ropes simultaneously, improve the machining efficiency that the round rope scalds the pressure.

It can be appreciated that the number of first arcuate through slots 1021 is equal to the number of second arcuate through slots 1031. For example, the number of the first arc-shaped through grooves 1021 is 2 to 8, and the number of the second arc-shaped through grooves 1031 is 2 to 8. Specifically, the number of the first arc-shaped through grooves 1021 is 2, 3, 4, 5, 6, 7 or 8, and the number of the second arc-shaped through grooves 1031 is 2, 3, 4, 5, 6, 7 or 8.

Further, when there are a plurality of first arc-shaped through grooves 1021 and a plurality of second arc-shaped through grooves 1031, the plurality of first arc-shaped through grooves 1021 are uniformly distributed on the first stamping piece 102, and the plurality of second arc-shaped through grooves 1031 are uniformly distributed on the second stamping piece 103. The first arc through grooves 1021 and the second arc through grooves 1031 are formed in a uniformly distributed mode, and accordingly consistency of pressing of the round ropes can be improved.

In a specific example, the round cord ironing device 100 further comprises a first ironing press mount 104 and/or a second ironing press mount 105. The first crimp mount 104 is connected to the first crimp 102 for mounting the first crimp 102 to the apparatus. The second crimp mount 105 is connected to the second crimp 103 for mounting the second crimp 103 to the apparatus.

Referring again to fig. 1, the cord ironing apparatus 100 further includes a driving mechanism 106; the driving mechanism 106 is connected with the first stamping part 102 and is used for driving the first stamping part 102 to move so as to realize the adjustment of the distance between the first arc-shaped through slot 1021 and the second arc-shaped through slot 1031. It is understood that the drive mechanism 106 may be, but is not limited to, a telescoping cylinder, a hydraulic drive mechanism, or the like. Preferably, the second stamping member 103 is fixed to the base 101. The second stamping part 103 is fixed on the substrate, and the distance between the first arc-shaped through groove 1021 and the second arc-shaped through groove 1031 is adjusted by adjusting the first stamping part 102, so that the adjustment is more convenient and quick.

In a specific example, the round rope ironing device 100 further includes a material guiding platform 107; a guide platform 107 extends outwardly from both ends of the base 101 for guiding the feeding and receiving of the round rope 200. Through the setting of guide platform 107, can further improve the stability of round rope in the course of working. Specifically, the second ironing piece 103 is fixed on the material guiding platform 107, and the first ironing piece 102 and the second ironing piece 103 are located on the same side of the material guiding platform 107.

It will be appreciated that the cord ironing apparatus 100 further comprises a feeding mechanism and/or a receiving mechanism; the feeding mechanism and the receiving mechanism are respectively positioned at two sides of the base 101 for feeding and receiving the round rope 200. Feeding and receiving are carried out to the round ropes through feeding mechanism and receiving mechanism respectively, improve the efficiency that the round ropes scalded press processing, accomodate the round ropes in order, improve the uniformity of processing scene.

In a specific example, the radius of the radial section of the first arc-shaped through slot 1021 of the round rope ironing device 100 used in the second ironing process is not smaller than the radius of the radial section of the first arc-shaped through slot 1021 of the round rope ironing device 100 used in the first ironing process.

More specifically, the radius of the radial section of the first arc-shaped through groove 1021 of the round rope ironing device 100 used in the second ironing process is equal to the radius of the radial section of the first arc-shaped through groove 1021 of the round rope ironing device 100 used in the first ironing process. Alternatively, preferably, the radius of the radial section of the first arc-shaped through slot 1021 of the round rope ironing device 100 used in the second ironing process is 0.2mm to 0.5mm greater than the radius of the radial section of the first arc-shaped through slot 1021 of the round rope ironing device 100 used in the first ironing process. For example, the radius of the radial section of the first arc-shaped through slot 1021 of the round rope ironing device 100 used in the second ironing process is 0.2mm, 0.3mm, 0.4mm, 0.5mm, or the like larger than the radius of the radial section of the first arc-shaped through slot 1021 of the round rope ironing device 100 used in the first ironing process. During the second ironing process, the thermal sublimation transfer medium 300 is attached to the surface of the transfer round rope, at this time, the radius of the radial section of the first arc-shaped through groove 1021 of the round rope ironing device 100 used in the second ironing process is larger than that of the radial section of the first arc-shaped through groove 1021 of the round rope ironing device 100 used in the first ironing process, so that defects of indentation, wrinkling and the like on the surface of the transfer round rope caused by size mismatch can be avoided, and the processing quality of the transfer round rope is affected. When the radius of the radial section of the first arc-shaped through groove 1021 of the round rope ironing device 100 used in the second ironing process is 0.2-0.5 mm larger than that of the radial section of the first arc-shaped through groove 1021 of the round rope ironing device 100 used in the first ironing process, the transfer printing round rope after the ironing process is finished has good surface consistency and high quality.

Further preferably, the fibers of the yarn are at least one of polyester fibers, nylon fibers, and nylon fibers. More preferably, the polyester fibers are cationic dyeable polyester fibers.

It is further preferred that the yarn is dyed prior to braiding the round rope. More preferably, the yarn is dyed to be light before the round rope is woven, the light color is easier to show the shape and the color of the pattern, and the color richness of the round rope is improved. For example, the light color may be white, tin white, goose yellow, pale pink, fruit green, pink green, pale blue, pale purple, etc. Still more preferably, the yarn is dyed with a cationic dye, an acid dye or a disperse dye. It is understood that cationic dyes dissolve in water in a cationic state and ionize in aqueous solution to produce positively charged colored ions. More preferably, when the yarn fibers are cationic dyeable polyester fibers, cationic dyes are used; when the yarn fiber is nylon fiber, acid dye is adopted; when the yarn fiber is the nylon fiber, disperse dye is adopted.

In the process of knitting the yarn into a round rope, the diameter of the knitted round rope is 2 mm-8 mm, such as 2mm, 3mm, 4mm, 5mm, 6mm, 7mm or 8mm, etc. Further, in the process of knitting the yarn into the round rope, the tightness of the knitted round rope is controlled to be: at 20g/cm ² The diameter deformation is less than 5% under the pressure of the steel wire rope, so that the steel wire rope can maintain good structural stability in subsequent processing.

It is understood that the temperature and time of the fixation treatment may be chosen and combined arbitrarily within the temperature and time ranges of the fixation treatments listed above.

After the fixation treatment, the water content of the round rope is higher. Thus, in a specific example, the round rope printing method further comprises the steps of: and drying the transfer printing round rope after the fixation treatment. Specifically, the temperature of the drying treatment is 60-100 ℃, and the time of the drying treatment is 1-3 h. For example, the temperature of the drying treatment is 60 ℃, 70 ℃, 80 ℃, 90 ℃ or 100 ℃; the drying treatment time is 1h, 1.2h, 1.5h, 2h, 2.5h or 3h.

Test case

The printed round ropes obtained in examples 1 to 3 and comparative examples 1 to 14 were respectively subjected to rubbing fastness, washing fastness, water fastness, perspiration fastness, storage fastness, washing shrinkage test and printed appearance. Wherein, the rubbing fastness testing method is carried out according to ISO 105-X16-2016 (the result is no less than grade 4 and is qualified); the washing fastness test method is carried out according to AATCC61 ℃ for 30min (the result is not less than grade 4 and is qualified); the water stain fastness testing method is carried out according to ISO 105-E01-2013 (the result is not less than grade 4 and is qualified); the perspiration fastness testing method is carried out according to ISO 105-E04-2013 (the result is not less than grade 4 and is qualified); the storage fastness test method is carried out according to AATCC163-2018 (the result is no less than grade 4 and is qualified); the water shrinkage test method is carried out according to ISO 139-2011 (the result is no more than 3 percent qualified).
