Abstract

A laminated fabric-like material used as the surface case of object (pillow for example) has a wet-bound non-woven surface layer laminated to an intenal porous polymer film. Said surface layer is treated for high fluid resistance, fire retarding and antibiotic nature. Said internal film is pore-formed for high breathability. Its advantages are high dirt resistance, breathability and durability and low cost.

Description

The breathable and spot-resistant cover that is used for goods

The present invention relates to be used for the breathable and spot-resistant cover of goods, for example pillowcase and cotton-padded mattress cover.

In commercial facilities, for example in hotel and the motel, the bed pillow is with the Woven fabric cover cap of cotton and polyester mixture.Described fabric is coated with a kind of finishing agent to stop the absorption of liquid.Yet, in practice, these be not very fluid-resistant and become by spot easily.Though be that independent pillowcase is used for the cover cap pillow and has therefore covered up spot to a certain extent, must can't be re-used and be dropped by the pillow of spot.

In hospital or long-term care facility, pillowcase or inner casing are normally made by the non-porous film.Must comprise passage in the side so that air is overflowed.These class pillowcases are noisy and are hot.

According to the present invention, a kind of cover or cotton-padded mattress cover are provided, it comprises film and fabric laminate products, and film be become in a controlled manner porous so that can be according to the type of pillow filler for example fibrefill or eider down and the gas permeability of regulating course stampings.Fabric is also preferably handled so that its spot-resistant and also available antimicrobial are handled with protective agent.

Fabric can be the fabric that conventional textiles is for example weaved or woven.Preferably, fabric is the nonwoven of making from fiber or monofilament.These comprise the nonwoven fabric of the fabric, multifilament and the composite that are made by the carded yarn fiber.Most preferably the supatex fabric that is made by the method that is referred to as wet method entanglement method (hydroentanglement) tangles into adhesive film with the thin current that spray with fiber web in this method.Suitable method is to be described among the US4379797, and it draws at this and is reference.There is modern method to utilize, wherein the flow roll of three-dimensional surface on carries out fixed so that fabric have fabric that the extra degree of depth and pattern and imitation weave or weave having fiber web.

Fabric can comprise natural or synthetic fiber or monofilament or their combination.Under the situation of wet method entanglement or other supatex fabric, fiber preferably includes polyester, though can use other fiber for example nylon, artificial silk, cotton fiber, polyolefin etc. and their mixture.Be preferred polyester and polyester blend in many cases, because they are now as the material in the related industries.Preferred fabric weight scope is every square yard of a 0.5-2.5 ounce.

With the fabric of web form by containing for example water slurry of Arichlorosan of the agent of acrylic acid flexible adhesion, fluorocarbon protective agent and antimicrobial.Excessive liquid is squeezed to come out and fabric is carried out drying from fabric.

As an example, the supatex fabric wet method is tangled to obtain through the compilation case.The basic weight of fabric is 1.8 ounces every square yard.After processing and drying, basic weight is to increase to 2.0 ounces every square yard.Fabric is carried out dry shrinking being used for fabric remained on their reset condition and prevent in tentering frame.

The tissue layer of handling thus is pressed into film, and the film fabric laminate products is handled to form the hole in film.Preferable methods is described in US3632269, and in 4381326,4690679,4806411 and 4859519, they are hereby incorporated by.Normally, nonwoven substrates is passed through from the metallic roll that is coated with teflon, this metallic roll is heated above or approaches the temperature of the softening point of the film that applied.Produce a slit between this roller and second roller, second roller is through the plating roller of silicone oil, rubber-coated and is maintained at about under the temperature between 45 ° to 70.Thin layer is sent in this roll gap, and wherein pressure is the 30-50 pound per square inch.The differential adjusting so that give the aeration of thin layer of the superficial velocity between two rollers is conditioned.Form a slit and be used for cooling and transfer lamination goods between the 3rd chill roll and second roller.

As an example, the basic weight that thin layer has is 0.5 ounce every square yard, so that the final weight of treated composite bed compressing tablet is to have 2.5 ounces every square yard basic weight.Suitable thin-film examples is: 77 parts of low density polyethylene (LDPE)s, 20 parts of methyl acetic acid methyl esters and 3 parts of titanium dioxide are as pigment.

Other suitable film comprises other polyolefin for example polypropylene, polyvinyl chloride, ethylene vinyl acetate, blend and copolymer.The weight of film can change between 0.2 to 0.75 ounce every square yard, and its prerequisite only is that film and fabric laminate are can be processed so that film is a porous.

The porosity of final composite is an important consideration.The porosity of the composite that records according to the testing procedure of standard should be 25-180 cubic feet per minute.For the pillow of fiber filled, what porosity can be in described scope is high-end, for example 80-110 cubic feet per minute.For the pillow of feather or eider down filling, porosity should be the low side in described scope, and for example 30-50 cubic feet per minute pierces through fabric to prevent feather.

The hydrostatic head of finished product fabric is to be in 8-15 centimetre the order of magnitude.The spot-resistant that records by alcohol drippage method of testing is 9-10, and it is corresponding to the isopropyl alcohol drop of opposing 90-100%.

The poroid film and the fabric that obtain with roll form can be cut into suitable dimensions, by sewing, fill with required elastic filler, and seal and make bagging.Certainly, laminated product can be used as protective sleeve that requirement has good spot-resistant and porous other object for example cover, backrest, furniture outer cover.

Used binding agent when by dry solidification, is used to keep the globality of fabric and also is used as keep protective agent and antimicrobial.

Preferably, composite fabric is arranged to make thin layer as skin.Continuous films has partly prevented the infiltration of liquid, and has stoped liquid to permeate by the hole in the film by handling fabric at the porose back side.
