TECHNICAL FIELD
[0001] The utility model belongs to the technical field of artificial turf, and particularly relates to a turf convenient to transfer. BACKGROUND
[0002] The artificial turf at present generally refers to woven turf, which is synthetic fiber in the form of imitated grass leaves, is implanted in woven base cloth, and is coated with a fixing coating on the back, and is used as turf on sports fields, leisure sites, golf sites, garden floor and greening ground.
[0003] Taking the artificial turf on a sports field as an example, different areas in the sports field can need different color turfs. At present, the general solution is to produce different color grass filaments or to dye the grass filaments first and then weave them on the base cloth to form the turf with specific colors. However, this processing method has many problems, such as the junction line of different colors can be arc-shaped or even irregular, which leads to the need of multiple color grass filaments on the same turf, which is troublesome in production, and secondly, multiple color materials need to be replaced in the production process, which has a certain influence on the production rhythm. Therefore, it is necessary to propose a turf convenient to print and dye, to simplify the production steps of the turf and to reduce the production cost. SUMMARY

BRIEF DESCRIPTION OF DRAWINGS
[0017] Figure 1 As shown in the schematic diagram of the lawn of the utility model.
[0018] Reference signs: 1-face layer, 2-bottom cloth, 3-back adhesive layer, 4-grass filament group, 5-row spacing. DETAILED DESCRIPTION
[0019] In order to more clearly illustrate the technical solutions of the embodiments of the present application or the prior art, the specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings described below are only some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative labor, and other embodiments can be obtained.
[0020] The technical solutions of the present application will be described in detail below with specific embodiments.
[0021] As Figure 1 shown, the utility model provides a kind of lawn of being convenient for transfer printing, can be directly used in printing and dyeing operation, which includes face layer 1, bottom cloth 2 and back adhesive layer 3, face layer 1 is artificial grass filament layer, is woven on bottom cloth 2, back adhesive layer 3 is set to bottom surface of bottom cloth 2, the needle foot of face layer 1 is covered, face layer 1 includes the grass filament group 4 of multiple rows settings, wherein, the tuft density of face layer 1 is greater than 30000 tufts, to ensure coloring.
[0022] The utility model is suitable for spray dyeing operation, easy to understand, spray dyeing is generally spraying dye in the corresponding area according to the set pattern from the upper surface layer 1 to the lower surface layer 1, and the tuft density of the grass silk has a great influence on the coloring effect, if the tuft density of the grass silk is small, more dye is sprayed on the base cloth 2 during the spray dyeing process, resulting in a decline in the pattern display effect.
[0023] Preferably, the height of the grass silk of the surface layer 1 is 3-10 mm. If the height of the grass silk is too short, the overall surface of the surface layer 1 will appear uneven, and the pattern display effect will obviously decrease. In addition, if the height of the grass silk is too high, the spray dyeing effect will greatly decrease. More preferably, the height of the grass silk of the surface layer 1 is 3-5 mm.
[0024] Preferably, the line spacing 5 of the surface layer 1 is 1 / 8-3 / 8 inch, and more preferably, the line spacing 5 of the surface layer 1 is 5 / 32-3 / 8 inch, for example, the line spacing 5 of the surface layer 1 is 1 / 4, 3 / 16, 5 / 32, 3 / 8, etc.
[0025] Further, the utility model is suitable for printing and dyeing operation in addition to spray dyeing operation. When the grass silk group 4 is pressed by a silk screen or other printing and dyeing component during printing and dyeing, the grass silk in front will not completely cover the adjacent grass silk in back. For example, most of the grass silk in back is in an exposed state, which is convenient for dyeing. If the height of the grass silk is too short or the line spacing is too large, printing and dyeing operation is difficult to realize in addition to affecting spray dyeing operation.
[0026] The difference between the utility model and the prior art lies in that the utility model is based on the lawn product for transfer printing. The transfer printing operation is not directly related to the lawn production process. The lawn does not need to replace grass silk of different colors during the production process, and does not need to produce grass silk of different colors or dye grass silk of different colors in advance. After the lawn is produced, the product is directly formed by transfer printing, unnecessary redundant processes are reduced, the production efficiency is improved, and the production cost is more easily controlled. The utility model is conducive to reducing the production cost.
[0027] In the transfer printing operation, the key lies in the size of the colored area of the grass silk and the size of the coloring force. The colored area affects whether the overall pattern of the lawn is clear, and the coloring force affects the printing and dyeing cost. The grass silk is easy to color, the amount of dye used is reduced, and the printing and dyeing steps are reduced, which is conducive to reducing the printing and dyeing cost.
[0028] The coloring force of the grass silk is related to the properties of the grass silk itself. In some embodiments, the grass silk is PP material or PA material. The coloring force of the grass silk of PP and PA materials is high, and the overall transfer printed pattern of the lawn is rich and delicate. To further improve the coloring force, the surface of the grass silk is rough, and the color on the surface of the grass silk does not easily fade during the use of the lawn.
[0029] The cross-sectional shape of the grass filaments is related to the ability of the grass filaments to retain color. The cross-sectional shape of the grass filaments is wavy, U-shaped or W-shaped. This cross-sectional shape is conducive to retaining the color of the grass filaments. During use, the gap portion of the grass filaments is not easily in contact with the outside world, and the dye attached in the gap portion is well preserved, so that the color of the grass filaments can be maintained for a long time. It is easy to understand that for grass filaments with a cross-sectional shape of a rhombus or an ellipse, during use, because the surface of the grass filaments is always in a state of being easily in contact with the outside world, the surface of the grass filaments wears out quickly, resulting in a change in the overall color of the lawn.
[0030] The overall shape of the grass filaments can also improve the coloring effect. In the present application, the grass filaments are open variable curved filaments, and the surface of the curved filaments is rough, which is easy to print and dye.
[0031] In addition, the grass filaments of the present application can also be open net filaments, which are easy to print and dye as a whole.
[0032] In the present application, the longitudinal needle density of the face layer 1 is greater than or equal to 350 needles / m.
[0033] The above provides a detailed description of the embodiments of the present application. In this paper, specific examples are applied to describe the principles and implementation methods of the present application. The above description of the embodiments is only used to help understand the core idea of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, the present application can be improved and modified. These improvements and modifications also fall within the scope of protection of the claims of the present application.
