Description

Oblate co-woven high-weight water-permeability base fabric

Technical Field

The utility model belongs to the technical field of artificial turf base fabrics, and particularly relates to an oblate co-woven high-weight water-permeable base fabric.

Background

In recent years, artificial lawns have been actively developed in accordance with the occupational, industrial, and commercial development of sports such as football, tennis, and golf. Compared with the traditional natural lawn, the artificial lawn has the advantages of bright appearance, green and lively seasons, good drainage performance, long service life, low maintenance cost and the like. Therefore, artificial lawns (carpets) are commonly used instead of natural lawns in most stadiums and various leisure and decoration areas.

In the prior art, the artificial turf mainly comprises a two-part structure, namely a basal layer (such as PP mesh cloth) and artificial grass filaments (usually drawn by PA, PP and PE materials). The artificial grass filaments are woven on the basal layer through a tufting process, and then the artificial grass filaments are fixed on the basal layer through the adhesion effect of the back glue layer, so that the complete artificial lawn is formed. However, the substrate layer is formed by densely weaving PP high polymer plastics, and the back adhesive layer is easy to block the grid eyes of the substrate layer, so that the water permeability of the existing artificial lawn is poor. The rainwater can not be discharged for a long time after falling on the lawn, the gum layer is easy to foam, accumulated water also easily wets shoes and socks of people walking on the lawn, and a large amount of accumulated water easily causes abnormal use or greatly reduces the service life in the weather with frequent rainfall.

Disclosure of Invention

The technical problem to be solved by the utility model is to overcome the defects in the prior art, and provide the oblate co-woven high-weight water-permeable base fabric which is used for solving the technical problems that the base layer of the artificial lawn in the prior art is poor in water permeability, water is easy to accumulate, and normal use is influenced or the service life is reduced.

The technical scheme for solving the technical problems is as follows: a oblate co-woven high weight water permeable base fabric comprising:

warp yarns;

weft yarns, wherein the weft yarns and the warp yarns are in a staggered weaving structure;

the weft yarns comprise round weft yarns and flat weft yarns, and the round weft yarns and the flat weft yarns are arranged at intervals.

The utility model uses the gap between the round weft yarns and the warp yarns as a drainage channel to drain water, so that the bottom is ensured not to accumulate water.

Further: the width of the warp yarn is 0.95-1.05 mm, and the thickness of the warp yarn is 0.085-0.095 mm.

The beneficial effects of the adoption of this step are: the warp yarn is flat in cross section and will conform more closely to the weft yarn.

Further: the diameter of the round weft yarn is 0.3-0.33 mm;

the width of the flat weft yarn is 2.234-2.3836 mm, and the thickness is 0.036-0.046 mm.

The beneficial effects of the adoption of this step are: the thickness of the flat yarn is approximately 10 times different from the diameter of the round yarn, the height difference is obvious, after the flat yarn and the round yarn are arranged at intervals, the warp yarn can be obviously jacked into a wavy shape, and the round yarn can enable the upper warp yarn and the lower warp yarn to be exposed out of the gaps for water drainage.

Further: the warp yarns and the weft yarns are PP plastic wires.

The beneficial effects of the adoption of this step are: the PP plastic yarn has good ductility and weather resistance, is easy to weave and is durable.

Further: the warp yarn has a yarn density of 200 yarns/10 cm and the weft yarn has a yarn density of 63 yarns/10 cm.

The beneficial effects of the adoption of this step are: through controlling warp yarn density and weft yarn density, the base fabric is enabled to form through holes with proper size, and drainage performance is improved.

The beneficial effects of the utility model are as follows:

the base fabric knitted by the oblate can avoid two conditions, namely, the warp and weft yarns are all flat yarns, the knitted base fabric is too dense, and the water permeability is poor; secondly, the weft yarns are all round wires, so that the base fabric is easy to deform due to the round wires, and the stability is poor; therefore, the oblate knitted base fabric can keep stability and water permeability, and no ponding exists.

Detailed Description

Embodiments of the technical scheme of the present utility model will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and thus are merely examples, and are not intended to limit the scope of the present utility model.

It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

Examples

As shown in fig. 1, the oblate co-woven high-weight water-permeable base fabric provided by the present utility model includes:

warp yarn 1;

weft yarns, which are in a staggered weaving structure with the warp yarns 1;

the weft yarns comprise round weft yarns 3 and flat weft yarns 2, and the round weft yarns 3 and the flat weft yarns 2 are arranged at intervals.

In the practice process, the artificial turf base fabric is found that when all weft yarns are flat weft yarns, the flat weft yarns are tightly attached to warp yarns, although the structural stability of the base fabric is good, the base fabric is waterproof, and when all weft yarns are round weft yarns, although the water permeability is good, the structural stability of the base fabric is poor because the round weft yarns are difficult to fix in the warp yarns, and the base fabric is easy to deform and separate from back glue. In the utility model, the flat weft yarns 2 and the round weft yarns 3 are arranged at intervals and are woven with the warp yarns 1 in a plain weave structure, so that the base fabric has both stability and water permeability.

On the basis of the technical scheme, the width of the warp yarn 1 is 0.95-1.05 mm, and the thickness is 0.085-0.095 mm.

The cross section of the warp yarn 1 is flat, and the warp yarn 1 is more fit with the weft yarn.

On the basis of the technical scheme, the diameter of the round weft yarn 3 is 0.3-0.33 mm;

the width of the flat weft yarn 2 is 2.234-2.3836 mm, and the thickness is 0.036-0.046 mm.

The thickness of the flat yarn 2 is approximately 10 times different from the diameter of the round yarn 3, the flat yarn 2 and the round yarn 3 have obvious height difference, after being arranged at intervals, the flat yarn 2 and the round yarn 3 can obviously push the warp yarn 1 into a wavy shape, and the round yarn 3 can enable the upper warp yarn 1 and the lower warp yarn 1 to expose gaps for water drainage.

On the basis of the technical scheme, the warp yarn 1 and the weft yarn are PP plastic wires.

The PP plastic yarn has good ductility and weather resistance, is easy to weave and is durable.

On the basis of the technical scheme, the yarn density of the warp yarn 1 is 200 yarns/10 cm, and the yarn density of the weft yarn is 63 yarns/10 cm.

Through controlling warp yarn density and weft yarn density, let the base fabric form through-hole 4 that the size is suitable, improve drainage performance, and combine the unit mass that warp 1, flat weft 2 and round weft 3 possess respectively, can let the base fabric have 200 g/-square meter's quality, the base fabric of this kind of quality combines the quality of gum, after laying artificial turf, can utilize the dead weight to keep artificial turf to level, reduce the destruction of impact force to artificial turf.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
