Description
Technical Field
The invention belongs to the field of sports equipment, and particularly relates to a processing method for water-absorbing printing of an anti-slip PU sweat-absorbing belt at a hand-held part such as a racket handle, the PU sweat-absorbing belt and application.
Background
The sweat absorbing belt is a layer of wrapping cloth on the hand holding part of the badminton racket and the tennis racket, and has the functions of skid resistance, sweat absorption and improvement of holding hand feeling. Sweat-absorbent tapes are generally composed of a glue or towel glue made of PU (polyurethane) material. The existing PU sweat-absorbing belt can lead to hand slipping or even the athlete to take off hands after absorbing human sweat, and three main methods for increasing the anti-slipping performance of the PU sweat-absorbing belt in the prior art are as follows: firstly, the appearance or the winding method (CN 202036750U, CN 103945908B) of the sweat-absorbent belt is changed, the friction is increased by changing the contact area with the hand and other mechanical improvements, the improvement modes are diversified, but the comfort of the hand is easily reduced; secondly, the overall chemical composition of the PU sweat-absorbent belt (such as CN 107641311A) is changed to achieve the effect of increasing friction force, so that the overall modification difficulty is high; thirdly, the anti-skid coating is used on the surface of the PU sweat-absorbent belt, the printing ink pattern is quite common, the ink consumption is low, and the spraying can be repeated, so that the anti-skid coating becomes an important direction for increasing the anti-skid performance of the sweat-absorbent belt. However, because the traditional pulse-like ink particles are larger, the pore channels in the PU sweat-absorbent belt structure are blocked, and the anti-skid function is easy to drop instead. There is therefore a need to develop new anti-slip inks and methods of spraying inks.
The adoption of the nano-grade ink (CN 103319953A and CN 107083112A) can effectively reduce the defect of large particles in the ink, and simultaneously increase the spraying effect and the dispersion characteristic of the ink. By combining the excellent performance of the nano-scale ink and adopting an advanced spraying technology, the anti-skid performance of the PU sweat-absorbing belt is expected to be improved.
Disclosure of Invention
The invention aims to provide a processing method for absorbing water and sweat after printing PU sweat-absorbing belt, which aims at overcoming the defects of skid resistance, absorbing water and sweat and the like of the PU sweat-absorbing belt in the prior art.
The processing method for the PU sweat-absorbent belt water-absorbent printing comprises the following main steps:
1. processing of PU quick water-absorbing fabric
(1) Impregnation of PU pulp
Conveying the water felted fabrics into the PU slurry tank through the conveying belt, so that PU slurry in the PU slurry tank is soaked on the surface and the bottom surface of the water felted fabrics;
(2) Pressing of PU (polyurethane) slurry
Rolling and pressing PU slurry soaked on the water felted needle fabric by a pressing device;
the pressing device is formed by continuously arranging three groups of roller groups, wherein the three groups of roller groups are a first wheel, a second wheel and a third wheel respectively, and the first wheel, the second wheel and the third wheel are formed by tightly arranging an upper roller and a lower roller up and down;
the shuttle mode of the water felted fabric in the roller pressing device is as follows: the first wheel passes through the middle of the upper roller and the lower roller of the first wheel, then passes through the upper side of the upper roller of the second wheel to be wound between the upper roller and the lower roller of the second wheel, passes through the lower side of the lower roller of the second wheel to be wound on the upper side of the upper roller of the third wheel, and finally passes through the lower side of the lower roller of the third wheel to be wound out;
the rolling press fit is realized by a roller in the press fit device, and the specific process is as follows: the upper roller of the first wheel is regulated to the surface of the water felted cloth soaked with PU slurry, and is pressed downwards in the rolling process, so that the PU slurry soaked on the water felted cloth is compacted, and the density is improved; meanwhile, the lower roller of the first round is attached to the bottom surface of the water felted fabric soaked with PU slurry, and the PU slurry soaked on the water felted fabric is uniformly pressed; then the upper roller and the lower roller of the second wheel and the upper roller and the lower roller of the third wheel are used for continuous and uniform rolling lamination; the rotation direction of the roller is determined according to the shuttle mode of the water felted needle fabric;
(3) Post-treatment
After being dried by a first oven, the PU quick water-absorbing fabric is foamed in a water tank and then dried by a second oven, so that the PU quick water-absorbing fabric is obtained and used for subsequent ink-jet printing patterns;
foaming to form a high-density small air hole layer on one side contacted with the upper roller of the first wheel, and forming an atmospheric hole layer on one side contacted with the lower roller of the first wheel, wherein the air hole volume in the small air hole layer is smaller than that of the atmospheric hole layer, and the air hole density of the small air hole layer is larger than that of the atmospheric hole layer;
2. inkjet printed patterns
During printing, the environment-friendly nano-scale color master ink is printed from one side of the PU rapid water-absorbing fabric with the small pore layer in an ink-jet mode through the Roland digital printer, and because the effect of the spraying force of the printer and the rapid water-absorbing ink-absorbing function of the high-density small pore layer can enable the environment-friendly nano-scale color master ink particles to pass through the surface layer of the PU rapid water-absorbing fabric small pore layer, the environment-friendly nano-scale color master ink particles are adsorbed at the bottom of the small pore layer of the PU rapid water-absorbing fabric, and then the environment-friendly nano-scale color master ink is rapidly dried through an oven at 60-70 ℃ to enable the environment-friendly nano-scale color master ink to be rapidly solidified, so that the PU sweat-absorbing belt is prepared.
The structure of the PU sweat-absorbing belt is as follows: the wear-resistant coating comprises a wear-resistant layer, a coloring layer and an atmospheric layer from top to bottom in sequence, wherein the wear-resistant layer and the coloring layer are high-density small-pore layers, the coloring layer also contains environment-friendly nanoscale color master ink particles, the wear-resistant layer does not contain environment-friendly nanoscale color master ink particles, and the coloring layer is printed from one side of the wear-resistant layer.
The PU sweat-absorbing band is used for winding the racket handle in such a way that one side of the PU sweat-absorbing band with an air hole layer faces the surface of the handle, the PU sweat-absorbing band is wound from the bottom of the handle, after a first circle is wound, a second circle is wound, the second circle can cover a part of the first circle, the whole racket handle is sequentially wound, the part of the handle, which is close to the PU sweat-absorbing band and covers the handle area, is a volatilization area, and the racket can be a table tennis racket, a badminton racket, a tennis racket and the like.
Compared with the prior art, the invention has the following beneficial effects:
(1) And (3) foaming the PU slurry in a special roller pressing mode to generate a small air hole layer and an large air hole layer with different air hole volumes. Specifically, in the foaming process, as the upper roller of the first wheel presses and rolls downwards to the surface of the water felted fabric soaked with PU slurry, the surface of the PU sweat-absorbent belt is pressed with large force, the PU slurry has higher density, a high-density small pore layer is formed in the PU foaming process, the water absorbing or ink absorbing effect of the water felted fabric is combined, the PU slurry has the effects of surface luster and wear resistance in the synthesis process, and the PU slurry is sticky, so that a layer of PU wear-resistant surface layer is formed. The first lower roller is attached to the bottom surface of the water felted fabric soaked with PU slurry, so that the PU slurry soaked on the water felted fabric is uniformly pressed, and an air hole layer is formed in the foaming process.
(2) Different air hole layers lead to special adsorption positions of the environment-friendly nanoscale color master ink, and a remarkable effect is generated. Specifically, the environment-friendly nanoscale color master ink is adsorbed and solidified on the lower layer (namely the coloring layer) of the wear-resistant layer and permeates into fiber gaps of the fabric, so that the environment-friendly nanoscale color master ink is high in color fastness and keeps bright color. The colored layer of the conventional sweat-absorbing band is actually on the surface, and the ink has blocked the pores of the surface layer, so that the sweat-absorbing effect is poor. In the invention, the color master particles are extremely fine, so that small pores of the coloring layer can not be blocked, and sweat absorption, water absorption and ventilation are easier. Sweat is close to the surface of the sweat-absorbing band and can enter into the small pore gaps of the coloring layer through the small pore gaps of the wear-resisting layer, and finally is absorbed into the gaps of the atmospheric pores through the suction generated by the high hygroscopicity and fast wettability of the water-jet knitted fabric, and volatilizes to the left and the right to be discharged into the sweat-absorbing band. In addition, the anti-slip function of the surface wear-resistant layer is not affected by the environment-friendly nanoscale color master ink. Compared with the traditional printing, the invention can absorb water and sweat and keep the viscosity of the PU sweat-absorbing belt surface.
(3) The racket handle wound with the PU sweat-absorbing band has excellent sweat-absorbing performance. Specifically, after the sweat absorbing band is wound on the racket handle, the sweat absorbing band starts to be wound from the bottom of the handle. After winding the first turn, a second turn is wound, where the second turn covers a portion of the first turn. Sequentially winding the whole racket handles. When sweat adheres to the surface of the PU sweat absorbing belt, the sweat is absorbed into the wear-resistant layer through the gaps rapidly by the high hygroscopicity and fast wettability functions of the water felting needle fabric, and then enters the atmospheric pore layer through the pore gaps of the coloring layer. Since the gap of the large pore layer is larger than the gap of the high-density small pore layer, the high hygroscopicity and the fast wettability of the large pore layer are higher than those of the high-density small pore layer, and sweat is absorbed into the gap of the large pore layer from the coloring layer and volatilized from both sides. Because the PU sweat-absorbing belt layer is wound on the racket handle, sweat is downwards dispersed layer by layer, and after passing through one layer, the sweat is dispersed into the gaps of the atmospheric hole layer by the fast wettability of the water felted yarn fabric, and the sweat cannot volatilize through the volatilization area, and enters the next layer to be continuously dispersed and volatilized through the winding coverage of the PU sweat-absorbing belt.

Example 5:
referring to fig. 5 and 6, the racket handle 22 wound with PU sweat absorbing tape exhibits excellent sweat absorbing performance, specifically as follows: after the PU sweat absorbing tape is wound on the racket handle 22, the PU sweat absorbing tape starts to be wound from the bottom 27 of the racket handle; winding a first turn followed by a second turn, wherein the second turn covers a portion of the first turn; sequentially winding the complete racket handle 22; when sweat adheres to the PU sweat-absorbing belt surface 23 and the PU sweat-absorbing belt bottom surface 24, the high hygroscopicity and fast wettability of the water felted needle fabric 1 can suck sweat into the wear-resistant layer 16 through the gaps, and then enter the atmospheric layer 14 through the coloring layer air hole gaps 18 of the coloring layer 15; since the gap of the atmospheric layer 14 is larger than that of the high-density small-pore layer 13, the high hygroscopicity and the fast wettability of the atmospheric layer 14 are caused to be higher than those of the high-density small-pore layer 13; therefore, sweat can be sucked into the gaps of the atmospheric pore layer 14 from the coloring layer 15 and volatilized from both sides; because the PU sweat absorbing band is wound on the racket handle 22 in a layer by layer; the sweat is dispersed downwards layer by layer, and once the sweat passes through one layer, the fast wettability of the water felted needle woven cloth 1 disperses the sweat into the gaps of the atmospheric hole layer 14, and the sweat volatilizes through the sweat volatilized area 25, and the volatilized sweat cannot enter the next layer to be dispersed and volatilized continuously through the winding cover surface 26 of the PU sweat absorbing belt.
