Detailed description of the invention

For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below will knot Close accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clear, It is fully described by, it is clear that described embodiment is only a part of embodiment of this utility model, and It is not all, of embodiment.Generally herein described in accompanying drawing and this utility model embodiment of illustrating Assembly can be arranged with various different configurations and design.Therefore, below to providing in the accompanying drawings The detailed description of embodiment of the present utility model is not intended to limit claimed model of the present utility model Enclose, but be merely representative of selected embodiment of the present utility model.Based on embodiment of the present utility model, The every other enforcement that those skilled in the art are obtained on the premise of not making creative work Example, broadly falls into the scope of this utility model protection.

In view of in correlation technique, mostly the careless silk that chinampa uses is long in shaft-like fiber one by one Silk, may there is following problem in this kind of traditional artificial grass filaments structure: (1) artificial grass filaments tough Degree not, the most easily produces broken yarn, and can present grass in chinampa finished product The problem that silk withdrawal force is little；(2) broken yarn during single fiber filament may produce bifurcated, production process Situation, when causing artificial grass filaments to produce, spool congestion situations is relatively common.

In order to solve chinampa grass silk in correlation technique objective present on the problems referred to above, this practicality is new Type embodiment provides the careless silk that a kind of chinampa uses, and as shown in Figures 1 and 2, this practicality is new The structure of the careless silk that the chinampa that type embodiment provides uses includes Artificial grass silk body 1, in order to strengthen The intensity of Artificial grass silk body 1, in this utility model embodiment, with Artificial grass silk body 1 as core, Outer wrap bag yarn 2 at Artificial grass silk body 1.

Wherein, the bag yarn 2 of Artificial grass silk body 1 outer wrap, Artificial grass silk body 1 can be strengthened Toughness, reduces Artificial grass silk body 1 broken yarn rate in process of production, improves finished product grass silk simultaneously Withdrawal force；The bag yarn 2 of Artificial grass silk body 1 outer wrap is formed Artificial grass silk body 1 further The constraint of bearing of trend, can improve the problem that the spool in Artificial grass silk production process easily blocks.

Bag yarn 2 is had, in order to make to be enclosed with the artificial of bag yarn 2 in view of Artificial grass silk body 1 outer wrap The careless silk that lawn uses is applicable to use and the serviceability of chinampa finished product of chinampa, this The dimensional structure of the careless silk that chinampa uses is optimized by utility model embodiment the most further, Wherein, the width of the Artificial grass silk body 1 of the careless silk that the chinampa of this utility model embodiment uses Being 1.3 millimeters～1.5 millimeters, thickness is 200 microns～350 microns, and the thickness of described bag yarn 2 is 0.1 Millimeter～0.2 millimeter.

In this implementation, the width of Artificial grass silk body 1 can be 1.3 millimeters～1.5 millimeters take Any value in value scope, such as, can be 1.3 millimeters, 1.35 millimeters, 1.4 millimeters, 1.45 millis Rice or 1.5 millimeters etc..

The thickness of Artificial grass silk body 1 is any value in 200 microns～350 micrometer ranges, such as may be used Think 200 microns, 201 microns, 202 microns, 203 microns ... 350 microns etc..

Further, the thickness of the bag yarn 2 of chinampa body exterior parcel can be at 0.1 millimeter～0.2 Any value in the span of millimeter can be such as 0.1 millimeter, 0.12 millimeter, 0.14 millimeter, 0.16 millimeter, 0.18 millimeter or 0.2 millimeter etc..

The value of the thickness of the width of Artificial grass silk body 1, thickness and bag yarn 2 can take above-mentioned Any value being combined in the range of value.

In this utility model embodiment, with Artificial grass silk body 1 as core, at Artificial grass silk body 1 Multiple implementation is had, such as, with Artificial grass silk body 1 as core, people during outer wrap bag yarn 2 The outside unidirectional winding one root length fiber of work grass silk body 1, is formed Artificial grass silk by this long fibre Parcel, strengthen Artificial grass silk toughness, such that it is able to reduce artificial lawn make time broken yarn rate and Reducing the generation of spool clogged conditions, that additionally can improve the artificial lawn made extracts dynamics.

With Artificial grass silk body 1 as core, in outside unidirectional winding one root length of Artificial grass silk body 1 During fiber, this long stapled unidirectional winding density can be configured according to the actual requirements, such as, and tool The unidirectional winding density of body is that every 10 millimeters of spacing being wound around between 2～8 circles, and each circle being wound around are equal, Wherein, the density of unidirectional winding can be 2,3,4 ... 7,8 circles.

In this utility model embodiment, with Artificial grass silk body 1 as core, at Artificial grass silk body 1 The mode of outer wrap bag yarn 2 can also be: with Artificial grass silk body 1 as core, at Artificial grass silk originally The outside of body 1 is wound around two root length fibers, and this two root lengths fiber crossovers is wound around, and winding direction is contrary.

Use two root length fibers to be wound around Artificial grass silk body 1, artificial silk can be increased with the less number of turns Intensity.

When using two root length fibers to be wound around Artificial grass silk body 1, two long stapled winding density can To be every 10 millimeters of windings 2～8 circle, and the spacing between same filament-wound each circle is equal.

It addition, mostly the careless silk that in correlation technique, chinampa uses is a shaft-like plastic entity, Elasticity and the orthostatic of grass silk can produce certain contradiction, in order to make to be wound with the Artificial grass silk of bag yarn 2 Having the most elastic and orthostatic, the Artificial grass silk body 1 in this utility model embodiment have employed Multiple structure, as it is shown on figure 3, the outer layer of Artificial grass silk body 1 is wearing layer 11, intermediate layer is for propping up Support layer 12, innermost layer is hollow layer, it is preferred that fill resilient layer at hollow innermost layer 13.

Its inner. layers structure of Artificial grass silk body 1 can promote the usability of Artificial grass silk further Energy；Such as: wearing layer 11 provides higher anti-wear performance, intermediate layer for Artificial grass silk further Good supporting role and upright performance are provided further；Inner hollow and resilient layer, it enters one Step ground provides good rebound performance for Artificial grass silk.

The Artificial grass silk simple in construction that this utility model provides, easy to use, reasonable in design, application spirit Live, it is possible to effectively from all many-sided lawn serviceabilities that promotes, the temperature environment of the suitable motion of construction, Emulation property is strong, is suitable to wide popularization and application.

Hereinafter the structure of the Artificial grass silk providing this utility model is described in detail, wherein:

One, wearing layer

Wearing layer 11 is arranged on the outermost layer of Artificial grass silk body 1, its have wear-resisting, resistance to compression is wear-resistant, Surface strength high；Above-mentioned wearing layer 11 can select various ways structure, but preferably selects For abrasion resistant fibrous layer or wear resistant resin layer.

Preferably can embodiment as one；Abrasion resistant fibrous layer specifically includes layer of polyester fiber or polyethylene Acetal vulcanized fibre layers, layer of polyester fiber or Polyvinyl acetal fibrous layer all have good wear-resisting And wear resistance.
