Abstract
The utility model provides overcanopying fabric. Surface fibers and inner fibers of the overcanopying fabric are respectively coated with a waterproof layer, and the size of gaps between yarns of the overcanopying fabric and the size of gaps between the fibers of the yarns are both smaller than 20 micro meters. The overcanopying fabric has the effects of preventing rain leakage and water dripping leakage, is light, breathable and water permeable, and can overcome the defects that conventional coating overcanopying fabric is hard in hand feeling and high in weight and can not be easily operated.
Description
Technical field
The utility model relates to a kind of overcanopy fabric.Especially, the utility model relates to a kind of without processing the overcanopy fabric that can obtain rainproof seepage and anti-pocket seepage function through film processing or overlay film.
Background technology
At traffic transport industry, need to hide the large transport airplane such as goods and materials, the automobile/aircraft/helicopter tool betransporteding with overcanopy fabric, damage goods and equipment leak to avoid drenching with rain; The large-scale Work machine of field work also needs to have overcanopy fabric to be opposite to the engineering machinery in field, particularly precision equipment to hide, and plays and prevents from, because of infiltration or the effect because of local pocket water seepage rainwater of drenching with rain, preventing the damage to equipment.Overcanopy fabric need to possess high-strength light simultaneously, not because of performances such as water suction are gained in weight, sun-proof is weather-proof; Overcanopy fabric for valuable cargo and military equipment use also needs to have fire protection flame retarding function.
But, current overcanopy fabric mostly is COTTON FABRIC or polyester-cotton fabric, easily leak, adopt the method for top finish or overlay film processing to improve leakage performance, the impact of can gaining in weight operates, and increases user's labour intensity, and can affect the poisture-penetrability of overcanopy fabric, the moisture that affects covered thing sheds, and increases cost; Conventional overcanopy fabric also can use operation because water suction weightening finish affects.For fire-retardant shelter cloth, have because adopting low intensive fire resistance fibre to cause the tensile tear-resistant undercapacity of fabric, service life is low; Have because adopting, the method preparation of COTTON FABRIC, dacron afterfinish exists that intensity is low, Boardy Feeling, the problem such as scent of even; In the time applying coating, must adopt flame retardant coating to take into account anti-pocket seepage performance and fire resistance, the gain in weight of flame retardant coating can reach 50g/m
2above, cause using shelter cloth, by very difficult shelter cloth operation when hiding on aircraft, vehicle and outdoor large equipment, more difficult fulfiling assignment in the time running into strong wind and heavy rain weather.
Therefore, lightweight, refuse water, rainproof and have certain anti-pocket water-based can shelter cloth have a wide range of applications demand.
Existing water repellent finish technology emphasizes fabric face to apply water repellent relatively.Adopting conventional padding method while applying water repellent finishing agent, even if adopt two to soak and two roll, even soak the water repellent rolling more and apply technology, be also not easy to make the really complete all fibres surface that is applied to fabric of water repellent finishing agent.The inventor finds, if fabric face and inner comprehensive surface all can be applied with to water repellent finishing agent, and make the size in the gap between the yarn in fabric also control to the size as the gap between the fiber in yarn, fabric entirety can have good rainproof effect, and has certain anti-pocket water effect simultaneously.The transport facility hiding for concrete needs, outdoor large equipment, or the article of outdoor stacking, can adopt suitable stacking structure design, or auxiliary equipment is set, make shelter cloth not occur the state of a large amount of pocket water, therefore, as long as allow fabric there is structure more closely, particularly there is no the gap hole of large-size, and overcanopy fabric is deeply evenly applied to water repellent, can utilize the additonal pressure of refusing water surface to form suitable anti-pocket outlet capacity, apply covering fabric to the requirement of the anti-pocket water of outdoor facilities enforcement rainproof to meet required the passing through of engineering practice.
Utility model content
The purpose of this utility model is to provide a kind of overcanopy fabric that has rainproof seepage and anti-pocket seepage performance concurrently that hides use for transport facility, outdoor job facilities or air storage goods.
For this reason, the utility model provides a kind of overcanopy fabric, it is characterized in that, the surface fiber of described overcanopy fabric and internal fiber all scribble water repellent layer, and gap size between gap size and the fiber of described yarn between the yarn of described overcanopy fabric is all less than 20 microns.
In a particular, the yarn twist factor of described overcanopy fabric can be 250～300.
In a particular, described overcanopy fabric is plain weave, and its warp-wise covers tightness and broadwise covering tightness is all greater than 63%.
In a particular, described overcanopy fabric is 2/1 or 1/2 twill-weave, and its warp-wise covers tightness and broadwise covering tightness is all greater than 74%.
In a particular, described overcanopy fabric is 2/2,3/1 or 1/3 twill-weave, and its warp-wise covers tightness and broadwise covering tightness is all greater than 81%.
In a particular, the fineness of the yarn of described overcanopy fabric can be 15tex～50tex.
The surface fiber of overcanopy fabric of the present utility model and internal fiber all scribble water repellent layer, therefore not only can be at fabric face, and can realize in fabric good anti-ly get wet, the effect of rainproof.And the size in the gap between the fiber in gap and yarn between the yarn of overcanopy fabric of the present utility model is all less than 20 microns, makes overcanopy fabric there is higher tightness degree, thereby avoid thicker existence capillaceous.And, the capillary additonal pressure that the capillary that gap between gap and fiber between yarn forms is higher because the effect of water repellent has, the hydrostatic pressing that the aqueous water that described capillary additonal pressure can be resisted corresponding height causes, prevents that overcanopy fabric is in use because occurring that pocket water phenomenon causes seepage.
Therefore, overcanopy fabric of the present utility model has the effect of rainproof seepage and anti-pocket seepage concurrently, has lightweight, ventilative, water vapour permeability, has avoided that conventional coating overcanopy fabric feeling is firm, Heavy Weight, not easy-operating defect.
