Description

A kind of ventilative suede nap composite material

Technical field

Technical field of textile fabric is the utility model is related to, more particularly to a kind of ventilative suede nap composite material.

Background technology

In textile composite fabric field, suede nap is commonly called as various FAUX SUEDEs, it includes cowboy's FAUX SUEDE, radial direction FAUX SUEDE, broadwise FAUX SUEDE, warp knit FAUX SUEDE, two-sided FAUX SUEDE, elastic force FAUX SUEDE etc..The suede nap fabric feel of wool is soft, there have to be glutinous Property, drapability is good, quality is frivolous, it is widely used in the fields such as luggage, clothes.The poor air permeability of suede nap, this will be influenced Its applicability, the existing fabric that sponge and suede nap is compound, to lift gas permeability.

It is well known that sponge is generally supported by expanded material, there are more slight void inside it, actually using Cheng Zhong, user can produce larger squeezing action to suede nap composite material, and spongy layer receives squeezing action and can shrink, when When user separates with suede nap composite material, the shape of spongy layer can restore automatically, during contraction and recovery, Certain air flow can be produced inside sponge, but limited be subject to traditional sponge internal structure, the speed of air circulation can be by To larger limitation, permeability needs to be further improved.

Utility model content

In view of the above-mentioned defects in the prior art and existing technical problem, the utility model devise a kind of ventilative suede nap Composite material, has stronger airing function.

Technical solution is used by the utility model solves its technical problem：A kind of ventilative suede nap composite material, bag Base cloth layer and spongy layer are included, the spongy layer includes the first spongy layer being arranged on the upside of the base cloth layer and is arranged on the base The second spongy layer on the downside of layer of cloth, the base cloth layer are formed by warp thread and weft yarns, and the warp thread forms one with the weft yarn Twill left to right tissue under upper two, the warp thread are single thread, and the weft yarn is the mixed yarn that two strands of single thread are mutually entwined, described First spongy layer and the second spongy layer are equipped with air hole, and the air hole hole wall longitudinal cross-section is arc, first sponge Air hole on layer is corresponded with the air hole on second spongy layer and connected with the cylindrical hole through base cloth layer It is logical, chamois leather pile layer is equipped with above first spongy layer, skid resistant course, the anti-skidding layer surface are equipped with below second spongy layer Quatrefoil protrusion is evenly distributed with, is adopted between the chamois leather pile layer, the first spongy layer, base cloth layer, the second spongy layer and skid resistant course It is bonded with binding agent.

The beneficial effect of above-mentioned technical proposal is：When user produces extruding to the composite material, extruding force can be successively The first spongy layer, base cloth layer, the second spongy layer, skid resistant course are transferred to from chamois leather pile layer, and the air hole two on the first spongy layer Stomidium mouth connects with chamois leather pile layer, base cloth layer respectively, the air hole both ends aperture on the second spongy layer respectively with base cloth layer, anti-skidding Layer connects, and the first spongy layer, the second spongy layer are connected by cylindrical hole, therefore, whole air hole inner space size It can extrude, in extrusion process, larger air flow can be produced at the aperture of air hole；

When user separates with the composite material, external compression power disappears, by the reply effect of sponge itself, and by It is arc in air hole hole wall longitudinal cross-section, when being squeezed or produces larger horizontal tension, the air hole after extruding disappears Quick-return original shape under tension, at this time whole air hole inner space be returned to original size, in Recovery Process, Larger air flow can be produced at the aperture of air hole；

Above-mentioned extruding, the change fit circular arc shape air hole replied, can cause sky more violent at the aperture of air hole Flow of air, and then the permeability of whole composite material can be substantially improved.

As the optimal technical scheme of the utility model, the air hole hole wall longitudinal cross-section is described ventilative to be arc-shaped Hole hole wall is raised laterally.

The beneficial effect of above-mentioned technical proposal is：Hole wall is arc-shaped, it is possible to reduce the stress concentration of hole wall, reduces hole wall Produce the probability of rupture；And the maximum Chengdu of energy ensures air hole inner space, lifts air permeability effect.

As the optimal technical scheme of the utility model, the air hole, cylindrical hole are arranged on adjacent warp thread and latitude Between yarn.

As the optimal technical scheme of the utility model, it has been coated with adding on the hole wall of the air hole and cylindrical hole Strong layer.

As the optimal technical scheme of the utility model, the enhancement layer is elastomeric material, and the reinforcement layer thickness is 0.1 ~0.2mm.

The beneficial effect of above-mentioned technical proposal is：Using elastomeric material, air hole and cylindrical hole can be effectively lifted Tension fragility energy, and elastomeric material is cheap, is conducive to control cost.

As the optimal technical scheme of the utility model, the warp thread is bamboo fibre, and the weft yarn is polyester fiber and gold Belong to fiber mutually to entwine blended form.

As the optimal technical scheme of the utility model, uniformly divide along its circumferencial direction equipped with four outside the bamboo fibre The rectangle groove of cloth, the bamboo fibre radial section are cross.

The beneficial effect of above-mentioned technical proposal is：Bamboo fibre has good gas permeability, instant water absorption, stronger wear-resisting Property and the characteristic such as good dyeability, while there is natural antibacterial, antibacterial, except mite, deodorization and anti-ultraviolet function again, and bamboo is fine Dimension is exterior to be equipped with groove, further lifts its gas permeability, polyester fiber and the blended effect with antistatic of metallic fiber, and resistance to Washing, light weight, price are low.

As the optimal technical scheme of the utility model, the skid resistant course is made of polytetrafluoroethylene (PTFE) and graphite, described poly- Tetrafluoroethene shared percentage by weight in skid resistant course is 60~70%, and the graphite shared percentage by weight in skid resistant course is 30~40%.

As the optimal technical scheme of the utility model, the anti-skidding layer surface is evenly distributed with quatrefoil protrusion, described Each quatrefoil protrusion is made of four arc shaped blades in cross distribution, and the quatrefoil height of projection is 0.2~0.3mm.

As the optimal technical scheme of the utility model, the binding agent is polyurethane.

The beneficial effects of the utility model are：Contrast the prior art, a kind of ventilative suede nap composite surface of the utility model Material, is effectively improved gas permeability, the durability of composite material, is process using multiple material, has multifunctionality, can be into One step meets consumer demand.
