TECHNICAL TERRITORY

The The present invention relates to products and methods for washing of sensitive or only to be chemically cleaned garments in a washing machine.

BACKGROUND THE INVENTION

The possibly most frequently used aqueous Laundry process is the one that a consumer or consumer performs when she or he is a garment in a watery Laundry detergent solution in a conventional one Household washing machine dips. Such a procedure already has for a long time as extraordinary powerful both for stain removal and for a total cleaning of garments and can without the use of dangerous or toxic chemicals. Furthermore is the application of an aqueous Laundry process in a conventional Washing machine considerably more convenient and cheaper than almost any other laundry method.

regardless whose can Such procedures lead to unacceptable results when used in a broad Spectrum of sensitive or only chemically clean Garments, like those made of wool. Wool is made of fibers, which interlock by a series of "scales" can. In general, you can These interlocking scales do not push past each other, which is why Wool a relatively strong Textile is. However, when wool becomes wet or moistened, it approaches the fibers on each other, and the woolen garment shrinks. This shrinking can not be undone because these "scales" only in a preferred Direction can push past each other. It can not be sufficient Power exercised be opposed to them in the preferred direction To move direction to reverse the shrinking. Therefore, at the removal of the woolen garment from the watery Laundry process a shrinkage occurred and the garment is irrecoverable damaged. In similar Rayon, when soaked in water, will be extremely sensitive, and probably the garment will be affected by the subsequent movement and the attrition to which it is exposed in a typical aqueous laundry process is not only badly damaged, but also extremely wrinkled. In similar Way sensitive fabrics like silk are not only crumpled heavily, but it can also mediate the desired softness mediated by it feeling get lost.

Garments like those made of silk are as well not only opposite sensitive to mechanical movement in a conventional washing machine, but also very sensitive to the typical laundry detergents, since such detergents may contain ingredients which are responsible for such sensitive substances too aggressive. Therefore, it is desirable to have an aqueous, for use in a conventional Washing machine adapted laundry process to provide that for clothes from fabrics like wool, leather, suede, rayon, silk, acrylics, Triacetates, fine cottons and mixtures of these above mentioned Materials not harmful is.

Therefore there is a need for a method of washing sensitive or exclusively chemical to be cleaned garments in a washing machine without the harmful ones described above Consequences. Furthermore there is a need for a convenient, inexpensive and effective method to sensitive and strictly chemical to garments to be cleaned Home to clean.

STATE OF TECHNOLOGY

THE ELASTIC WRAP CONTAINER

It has long been known that the mode of action of the agitator in a clothes washer sensitive Exposing substances to abrasion and stress that are sufficient to severe damage to be able to cause. As a result, bags have been developed which are used in a washing machine can be around these clothes to protect against abrasion and stress. Nonetheless, these have turned out to be different for a variety of reasons proved insufficient. First, they are generally too small than that they take more than one or two small pieces of clothing could and even then the garments may be crumpled up and Creasing and loss of form increased. Second, dispose many of these bags do not over a reliable one Closure means, so that the bag often opens during the washing process, whereby the clothes are not get more the protection they're supposed to get through the bag, and abrasion and wear of the clothes probably increased become. Third, these bags are often designed to make an outer shell a grid-like Have mesh, the contact between the wash liquor and the clothing allows However, to provide cleaning benefits, this grid-like pattern may also leave an identical grid print on the inside garments. One such pattern may be difficult to iron out.

An embodiment of an elastic winding container ("roll") made in accordance with the present invention which overcomes many of these problems is disclosed in US Pat 1 . 1A and 2 shown. The wrap 122 may be of any suitable size and shape. In the in 1 . 1A and 2 In the embodiment shown, the winding comprises 122 a single, preferably rectangular track 100 , The dimensions of the web 100 are such that the width is about 30.5 cm to about 91.4 cm and the length is about 55 cm to about 117 cm; more preferably a width of about 40.6 cm to about 81 cm and a length of about 66 cm to about 107 cm, and most preferred is a width of about 51 cm to about 71 cm and a length of about 76 cm to about 97 cm. In a rectangular embodiment, as in FIG 1 is shown, the distance from the upper edge of the web 102 to the bottom of the track 101 preferably greater than the distance from the right edge of the web 103 to the left edge of the track 104 ,

The wrap 122 preferably further comprises one or more bands 108 which is adjacent to the top of the track 102 are attached. At one end of each band is a first attachment device 109 which can be fixed and permanently attached to each band 108 is fixed so that their position on the belt does not change. A second fastening device 106 is preferably attached to each band by pulling the band through the fastening device such that by changing its position on the band, the length of the band 105 can be increased or decreased. The first and second attachment devices cooperate to secure the elastic winding container in a roll form during use (see, eg, FIG. 7 ) or in a folded form (see eg 16 - 19 ) to fix. In addition, preferably two bags 110 adjacent to the upper edge of the railway in the 1 . 1A . 2 and 3 attached way shown. As discussed in more detail below, the pockets 110 be used for storing the bands and fasteners when they are not needed.

The fasteners used herein are preferably reusable mechanical fasteners. Any reusable mechanical fastener or reusable mechanical fastener may be used. Non-limiting examples include: closures wherein the first and second attachment devices together comprise a hook and loop fastener circuit (VELCRO ^® -type) include; Hook fasteners as described in U.S. Patent No. 5,058,247 to Thomas & Blaney, issued October 22, 1991; Closures, wherein the first and second attachment devices together comprise a hook and cord fastener; Closures, wherein the first and second attachment devices together comprise a tension lock; Closures, wherein the first and second attachment devices together form a snap closure; and hook-and-loop fasteners, zippers, releasable buckle fasteners as used in U.S. Patent No. 5,330,141 to Kim, issued July 19, 1994, and the like, as long as the fasteners do not result in the closures contained in the pouch Garments are torn or rubbed off. As will be apparent, a single fastener may also be used with one or more straps to secure the winding container in its rolled or folded configuration.

The elastic wrap container may be constructed of any suitable material, including but not limited to: fabric materials, nets, scrims, and nonwoven materials. The structural elements or parts (eg, the strands, fibers, threads, yarns, etc.) of the coil may also comprise any suitable material or materials. Suitable materials for these structural components of the roll are selected from nylon, polyethylene, polypropylene, polyesters, and combinations thereof. The structural components of the coil 122 are coated with an acrylic material. The material or materials that make up the winding can be present in one or more layers. If multiple layers of material are used, the (constructive components of) layers can be made of the same material or of a different material. The layers may comprise the same type of structure or a different type of structure. When multiple layers of material are used, the layers may be joined together directly or indirectly by any known bonding method. The elastic wrap is preferably designed to have a density that is greater than the density of water at standard temperature and pressure so that the elastic wrap container is more likely to sink into the wash liquor and thus provide better wetting and rinsing garment contained therein. The material should be elastic but strong enough to be used multiple times. To insure that water can easily penetrate through the wrapping material to contact the garments it contains, the wrap is 122 preferably provided with a row or a plurality of holes or other openings, or the wrapping material should be water permeable.

The wrap 122 is provided with holes or openings, the size and number of openings are large enough to allow water and any cleaning solution that is outside the coil 122 to wet the garments to be cleaned, as well as to allow dirt particles to be transported away from the garments. The holes or openings are preferably not so large that parts of the garments to be cleaned are excessively exposed to damages in the washing machine or embossed with the pattern of the coil.

The wrap 122 is elastic enough for the garments it contains to be subjected to some mechanical movement to aid in the cleaning of the garments, yet stiff enough for the wrap to enclose the garment and for the garments not to be subject to excessive creasing, excessive abrasion, and excessive shrinkage ,

The elasticity (or rigidity) of the wrapping materials described herein measured by Taber stiffness measurement (ASTM D5342). The Stiffness of the wrapping material may be in one direction relative to Fabric or to measure the weft material, or it can be measured in two directions (as in the case of Square fabric in a first direction parallel to the winding yarns or, and in a second direction at right angles thereto (e.g. parallel to the weft threads). When the stiffness of the wrapping material measured in two directions The Taber stiffness measured in two directions can be averaged become. The wrapping material preferably has a stiffness in one direction as well as an average stiffness in two Directions between about 3 and about 90 Taber stiffness units, more preferably between about 10 and about 50 Taber stiffness units on. The lower end of the above range may be larger than 3 Taber stiffness units. For example, the lower end be any number within the range (e.g., 4, 5, 6, ... etc., 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70 or 75), although the number is not specified herein.

One non-limiting example for suitable materials for the wrap is a woven fabric material of woven, acrylic coated Polyester (ACP).

The woven acrylic coated polyester (ACP) material is preferred because it is somewhat stiffer than the DNB material and without any specificity As a result, it is believed that it is better able to grip the garments and keep them under tension in the state / position in which they are originally placed in the wrap and to prevent the movement of To reduce garments within the coil during the washing process while allowing water and cleaning solution to easily enter through its porous structure. This has led to improvements in reducing creasing, abrasion and shrinkage of the garments after washing. The woven acrylic-coated polyester material has the desired stiffness in a structure that has a very small thickness or three-dimensionality. This is in contrast to the double needle bar material, which consists of three different types of yarn to give it the appearance of three layers, each "layer" being very elastic but having stiffness when combined into a relatively thick three-dimensional structure, which is bigger than one of the "layers" alone. The woven acrylic-coated polyester material is a single-layered material having a single type of thread and thus can be considered as a two-dimensional material.

The Stiffness of materials used in the winding can be varied by methods familiar to those skilled in the art the production of such materials are known. For example takes care of adding the acrylic coating for additional Rigidity. About that can out modified weave / knitting patterns and / or the type of yarn or thread, which is used for weaving or knitting a fabric, the stiffness of the roll increase or decrease.

Preferred woven acrylic coated polyester materials are the material numbers 961376 and 961377, available from Milliken & Company, Spartanburg, SC. The filaments of these materials preferably have a diameter between about 0.1 mm and about 0.3 mm, and more preferably have an oval cross section with a smaller diameter of about 0.14 mm and a larger diameter of about 0.23 mm , One of these materials (961377) has square-shaped openings in the tissue which are approximately 1 mm x 1 mm in size. The total open area of this material is approximately 0.6 mm ² / mm ² (open area in mm ² per square millimeter of material). This material is stretchable in one direction but not in a direction at right angles thereto. The other material (961376) has rectangular openings about 1.5 mm x 2 mm in size. This material is about 0.5 mm thick. The total open area of this material is approximately 0.7 mm ² / mm ² .

Of the Wrapping can optionally consist of materials that have every potential for the absorption of volatile Reduce dyes through the wrap from garments in it gewa clothes. The wrap may, for example, be a soil release polymer or have another material with this property, which in one included or applied to it in any suitable manner. For example, a soil release polymer of the type described herein Type on the structural elements that make up the winding (eg the yarns) are applied. In another non-limiting Example may be a soil release polymer in the material, from the constructive elements of the coil, before or during the Formation of these constructive elements are included. In Yet another example may be a soil release polymer in any coating that is on the constructive Elements of the coil is applied (for example, the dirt-repellent elements to be included in the acrylic coating). The oversight of the Winding with such materials reduces the potential for absorption of fleeting Dyes and for color change through the wrap and supported Make sure the user of the wrap doing that through the wrap no dyes are removed from the washed garments or that such dyes are not transferred to other garments.

The method by which the coil is used in the present invention is simple. An article of clothing 120 Exercise reasonable care in the web section of the roll 100 so that no part of a garment is outside the dimensions of the web. After the garment has been placed on the web, the wrap can then be rolled up in one embodiment, starting at the bottom of the web 101 Just as a sleeping bag is rolled up after use for storage purposes. The wrap should not be rolled up so tightly that the garment inside it may be exposed to excessive creasing. After completion of the coiling, the winding should be 122 be in the spiral shape, as in 7 shown. As in 7 As can be seen, the length of each band has been adjusted so that when the first and second fasteners engage, the bands secure the rolled up roll.

Alternatively, the wrap may be folded instead of rolled up. In 16 to 19 there is shown a non-limiting embodiment of a folded roll with the roll folded twice to form a four-layered structure. The wrap may be folded in any other suitable manner. For example, can the reel can be folded in half, or the reel can be folded into a structure of three or more layers. Folding the roll, rather than curling, may tend to reduce wrinkles on some washing machines (especially Japanese washing machines) after washing.

Adjacent to the lower edge of the web are at least two, preferably at least four connecting means 107 which are push buttons in a preferred embodiment. The wraps are constructed to have an enlarged wrap 125 by joining two coils by means of the connecting means 107 which are located adjacent to the lower edge of each lane can be constructed. This construction is in 2 to see. When the coils are so connected, the path of one coil partially overlaps the path of the other coil, as in FIG 2 you can see. An enlarged wrap 125 can be larger garments (like a dress 121 ) record as a single roll 122 ,

If two wraps by means of the connecting means 107 which are adjacent to the lower edge of each lane, are interconnected as in the 2 illustrated alternative embodiment, is an additional set of bands 108 and first and second attachment devices 106 . 109 available. The straps and fasteners are then stored in the nearest pocket 110 placed.

In a preferred embodiment, the winding further consists of two envelopes 111 . 112 , The envelopes are along the right edge of the web 103 and along the left edge of the track 104 attached to the railway. Each envelope has a surface that is about ½ to 1 times the surface area of the web to which it is attached. Thus, when the envelopes are folded inwards and placed on the web surface, they completely cover the web, essentially adding a second web layer to the web. In the in 1 . 1A and 2 As shown, each envelope has a matching sinusoidal configuration. The mating sinusoidal shape adds to the overall integrity of the rolled up roll by having the two envelopes 111 . 112 tighter than if the envelopes had a conventional rectangular shape and is believed to reduce the compression of the wrap and the creasing of the garments contained therein. 1A shows these two envelopes: a folded one 111 and a folded over the track 112 , The envelopes 111 . 112 and the train 100 are also with mounting devices 114 equipped, which is adjacent to the upper edge of the train 102 are located. When fastened together, these fixtures secure the envelopes to the web 100 ,

In one embodiment of the present invention, the wrap is constructed of four different layers, as in FIG 4 shown. These four layers provide a considerable amount of padding to the delicate garments that can be placed in it. The train 100 is a layered material that is a core material 131 between a first layer material 130 and a second layer material 132 wherein the core material is polyester, the first layer material and the second layer material are nylon and the first envelope and the second envelope are each constructed of polyester. Optionally, the second layer of nylon material and the polyester material forming the envelopes are woven to have numerous small holes or pores through which water can either enter or exit the interior of the coiled roll while the second layer material does not overflow has such holes, but is permeable to water.

If the preferred elastic winding container is used, he can to pick up two pieces of clothing: one placed directly on the track and another, the one on the envelopes is laid after she over the piece of clothing folded on the track.

With reference to 8th and 9 another example of the invention produced, preferably elastic winding container is illustrated. The elastic winding container 134 includes the elastic web 100 and a first envelope 111 and a second envelope 112 , The first and the second envelope 111 and 112 each preferably have a width which is about the width of the elastic web 100 equivalent. More preferably, the first and second envelopes 111 and 112 a width of between about 40 cm and about 70 cm for an elastic web 100 with a width between about 45 cm and about 72 cm. In other words, the first envelope extends 111 preferably adjacent to the right edge of the web 100 when the first envelope 111 over the left edge of the train 100 folded, and the second envelope 112 preferably overlaps the first envelope 111 if he is over the right edge of the web 100 is folded, and extends adjacent to the left edge of the web 100 , The elastic web 100 and the first and second envelopes 111 and 112 can be provided as separate structures and on the elastic web 100 be attached, or the elastic web 100 and the envelopes 111 and 112 can be made of a uniform material be formed. Although the distal or unattached edges 136 the envelopes 111 and 112 are shown as being straight, other edge configurations, such as the sinusoidal shape described above, may be provided. Further, any number of mounting devices 114 (eg, snaps, velcro, magnetic fasteners, etc.) along one or more of the distal edges 136 the envelopes 111 and 112 be provided to the envelopes to each other and / or on the elastic web 100 to fix.

Further with reference to 8th and 9 deliver the overlapping envelopes 111 and 112 several advantages. For example, the distal edges 136 the overlapping envelopes 111 and 112 through the increased width of the envelopes 111 and 112 to the right and left edge of the train 100 towards and from the contact with the garment 120 moved away. This can reduce the likelihood that sutures of the distal edges 136 during use of the elastic winding container 134 an impression on the garment 120 leave. The overlapping envelopes 111 and 112 Make an extra protective layer for the garment 120 and can reduce the risk of parts of the garment 120 from the elastic winding container 134 In addition, the overlapping envelopes provide 111 and 112 for an elastic winding container that can hold several garments. For example, the envelopes 111 and 112 spread out to the elastic web 100 to release, as in 8th shown. The piece of clothing 120 gets over the elastic web 100 put, and one of the envelopes 111 or 112 is about the garment 120 folded, as in 10 shown (where envelope 111 as shown folded over the garment). The piece of clothing 138 is then folded over the folded envelope (eg envelope 111 ), and the remaining envelope (eg envelope 112 ) is about the garment 138 folded and with the help of the support devices 114 , if available, secured. Subsequently, the elastic winding container 134 rolled up and with the aid of the first and second fastening devices 106 and 109 secured.

Although the width of the overlapping envelopes 111 and 112 will be discussed herein as extending preferably to the right and left edges of the web 100 adjacent, the width of the overlapping envelopes is 111 and 112 preferably between about half and full width of the web 100 , As an alternative, although less preferred, a single envelope may have a width that is approximately equal to the width of the web 100 is, instead of the two overlapping envelopes 111 and 112 to be provided. Such an embodiment would preferably be holding devices 114 to secure the single envelope to the elastic web.

Yet another preferred elastic winding container is in 11 shown. The elastic winding container 140 includes an elastic web 100 that is a major part 142 having a right edge, a left edge and a bottom edge. The elastic web 100 also has a tapered top 144 on, that at the main part 142 is attached. The top 144 has a tip 146 that is at the center of the main part 142 is arranged. The length of the pointed top 144 is preferably at least about half the length of the main part 142 , More preferably, the length of the top is 144 between about 40 cm and about 50 cm with a main body having a length between about 75 cm and about 80 cm. A single band 108 is adjacent to the top 146 of the top 144 attached. At one end of the band is a first attachment device 109 that can be fixed and permanently attached to the band 108 is fixed so that their position on the belt does not change. A second fastening device 106 is attached to the band as discussed above.

The inwardly directed tapered top 144 and / or the provision of a single band 106 adjacent to its top 146 can have several surprising advantages during use of the elastic winding container 140 Offer. When the tapered shell 144 during use over the bulk 142 rolled, as in 12 shown, it gives the rolled elastic winding container 140 an additional structure through spiral layers 144 that the main part 142 surrounded when it is rolled up. This additional structure helps maintain the roll shape of the elastic winding container 140 so that garments stored in the wrap will require less final assembly work since the elastic wrap 140 less likely to twist or roll off due to the washing machine movement. The elastic winding container 140 with its centrally arranged band 108 in conjunction with the tapered top 144 It also better counteracts the formation of gaps between layers of the rolled-up wrapper through the parts of a garment 120 such as sleeves or a collar, during the washing machine movement can be pulled out. Although the tapered top illustrated herein 140 or 144 is preferred, other tops can be provided according to the present invention. For example, the top part 144 to the right and / or left edge of the main part 142 be offset or with a size ren tip or a lesser rejuvenation.

With reference to 13 . 14 and 15 Yet another preferred elastic winding container made according to one aspect of the present invention is illustrated. The elastic winding container 148 has an elastic web 100 with a right edge, a left edge, and a bottom edge. Adjacent to the right and left edges of the track 100 there is a border each 150 , The borders 150 may be provided instead of the envelopes described above for retaining a garment within an elastic wrap container. The borders 150 can be made from a variety of loops 152 are formed, whose ends 154 and 156 on the elastic web 100 are attached. The loops 152 can be formed of polyester fibers or a similar material and by sewing, heat welding, hot melt adhesive, cold adhesive, ultrasonic welding, etc. on the elastic web 100 be attached. The loops 152 are preferably in a first row 158 arranged, with the loops 152 the first row are arranged end to end, and in a second row 160 wherein the ends of the loops are also disposed substantially end-to-end. Preferably, the first loop begins 162 the second row 160 at the middle of the first loop 164 the first row 158 , as in 13 shown, and the opposite end of the first loop 162 the second row 160 ends approximately at the midpoint of the second loop 170 the first row 158 , although the starting point of the second row may vary. The loops are preferably substantially flat when the elastic wrap container is unrolled and are resilient enough to move from the elastic web 100 to stand so that loops from the first and second rows 158 and 160 overlap each other around the open border 150 to form the openings 172 has, as best in 14 can be seen, can flow through the wash liquor, but small enough so that the garment during use is not from the elastic winding container 148 can escape. The fibers forming the loops preferably have a thickness between about 0.25 mm and about 3.175 mm, and the openings 172 have an open area between about 1.5 cm ² and about 4.8 cm ² .

Although the first and second rows 158 and 160 will be described herein as having different rows, it will be understood that a single row may be provided instead of two rows or that more than two rows may be used. Further, it will be appreciated that the strength and spacing of the loops may be changed to achieve varying degrees of longitudinal elasticity and garment retention in the transverse direction. Furthermore, the length of the borders 150 vary longitudinally, although it is preferred that the length be adjacent to the upper edge of the web 100 until adjacent to the bottom of the train 100 extends.

Of the Coiled or folded wraps can be used in any be placed in the washing machine in a suitable manner. Usually The wrap is placed in a US machine by bending slightly will take him to the agitator around before turning on the machine. The wrap can without a special means to keep him in his position, placed in the washing machine who the. As an alternative, a suitable Holding device used to wrap the tub in the tub Keep washing machine in a specific position.

In one embodiment, as in 20 For example, when laying the roll in the tub, it can be shown 220 of the washing machine 222 a holding device, like a net 224 , over which wraps are placed to keep the wraps submerged and to prevent the wraps from floating during the washing process. This will ensure that the garments contained in the wrap are adequately wetted and completely cleansed. This is a particularly useful variation in the case of mild washing conditions and short washing times in washing machines used in Japan, the water being circulated mainly horizontally through a disc at the bottom of the washing tub. These machines are different from US machines where the water moves in a vertical, circular motion that tends to pull the coil down to the bottom of the wash tub.

In the case of in 20 shown embodiment is a network 224 used, which extends over the interior of the tub of the washing machine and is arranged above the winding. The mesh can be stretchable or non-stretchy. The network may be of any suitable size. For example, the net may have a diagonal dimension between 20 and 40 cm when unstretched. The mesh may have any suitable shape, including but not limited to: square, rectangular, triangular, and circular. The net may be made of any suitable material. The net should be permeable so that it does not affect the flow of water in the washing machine. In one embodiment, the mesh is a stretchable elastic material having a square configuration and in the unstretched state 22 cm x 22 cm is great. This net has sixteen square shaped openings, each about 5 cm by 5 cm in size.

The net may be held in place in any suitable manner. In the in 20 In the embodiment shown, the net is held in place by four metal hooks which engage in the holes in the inside of the tub of the washing machine. The net is not limited to being held by four hooks. Any suitable number of hooks (including between 3 and 10 hooks) is possible. The hooks may be made of plastic or of any other suitable material. In other embodiments, the mesh may be held in position by other types of devices than metal hooks. Some non-limiting examples of suitable devices for holding the net in place include: suction cups, magnets, and stickers.

In other embodiments the holding device may be another suitable device than a Net include. Any device that fits the winding in the Washing machine in its position is suitable. For example could the wrap with ribbons be hooked into the tub. As an alternative, the Wraps are weighted to keep him submerged. In other embodiments The winding can be done with magnets attached to the inside of the washing tub can be fixed be equipped to hold him in his position. these are just a few examples of suitable holding devices.

Of the Garment container acts a shrinkage of the garments contained therein, leaving the garments over five wash cycles a shrinkage ratio (Dimensional change in%) of less than or equal to about 15% (eg, between about 0% and about 15%). The shrinkage ratio (dimensional change in%) according to the test procedure measured in terms of shrinkage of an entire garment, the following in the section about the test methods is described.

Of the Clothing container has preferably a wetting effect on the garments contained therein between about 90% and about 100%, more preferably at least about 95%, and on most preferably 100%. The wetting effect on the garments becomes after the wetting test procedure as described in the section on test methods below.

Of the offers elastic winding containers disclosed by the present invention considerable advantages compared to currently common ones Devices. In particular, it offers a better means to own Save and close, whereby the possibility that garments fall out of it and while washing in a washing machine is restricted. About that Insulates and protects the elastic winding container the piece of clothing or the clothes, which are contained therein, before the stress and the Abrasion caused by the agitator and other internal parts of a washing machine can be caused. Of the elastic winding container It also offers extensibility and versatility for others such devices are not present: The elastic winding container is not only bigger than Competing devices, but also has a number of fasteners (eg snap closures) on, creating two identical elastic winding containers via snap closures to each other can be fixed for an additional elastic winding container which is twice the original capacity of the elastic winding container having. This will provide the benefits of the present invention further improved in terms of dimensional maintenance.

PROCEDURE

Wetting test methods

Standard washing conditions:

• Washing Machine (Sears Kenmore Series 90)
• Medium water level (64 liters (17 gallons))
• Cold water temperature (15.5 ° C (60 ° F)) for washing and rinsing
• Motion adjustment Extra Delicate
• 6-minute "Ultra Clean "-Waschzyklus
• 1 rinse selected

Method:

Wetting Experiment

• 1. A 100% wool sweater in the garment wrap lay. The sleeves just lay down along the sides of the sweater (not to cross in the middle, to avoid covering the front of the pullover, causing their wetting is impaired would).
• 2. The garment wrap roll up in the usual way.
• 3. Using the standard washing conditions, the washing machine switch on and fill to let.
• 4. After filling with water and starting to move, put the garment wrap with the sweater inside it on the surface of the water in the machine (do not immerse). (Through this wetting experiment wetting should of a garment are measured in an aggravated condition in that wetting tends to be more easily achieved when the garment wrap is placed in the wash tub before the wash tub is filled with water.)
• 5. At the end of the wash cycle, the machine will start draining of the water.
• 6. After the water has been drained from the machine, the Switch off the machine before the spin cycle begins.
• 7. The garment wrap Place on a flat table and unroll or unfold.
• 8. Immediately with the measurement and logging of dry Areas on the front of the pullover and on both sides of the Arms start (dry areas appear much brighter than the wet areas). The dry areas are going through as possible Precise measurement of the dimensions of the dry areas by means of a Scale (ruler) and calculate the area of each dry area measured.
• 9. To an approximate To calculate percentage of dry areas, the sum of dry Areas through the measured area of Divide front and arms. The wetting effect is determined by subtracting the percentage of dry areas from 100% becomes.

Shrinkage test procedure - entire clothing

This Method is used to prepare and evaluate all garments for measurement the fabric shrinkage.

definitions:

dimensional change (Dimensional Change, DC) - Changes the fabric length or width. expressed as a percentage of the initial ones Dimension of the fabric.

Shrinkage - a dimensional change that to a decrease in length or width of the swatch leads.

Method:

Preparation of the garment:

• 1. Three different types of garments for Determine and obtain rating. Recommended fiber types include: Rayons, rayon acetates, Silk and wool. Both woven and knitted fabrics as well a variety of garment styles (Dresses, blouses, pants, blazers, skirts).
• 2. Four garments Each sample should be used to increase the accuracy of the averaging increase.
• 3. Every garment At least 4 hours in a controlled environment room (21 ° C (70 ° F), 65% relative humidity) by hanging on a hanger condition. If an article of clothing usually not on a hanger hanged will, the garment Place on a sieve of a conditioning rack.
• 4. With smudge-proof marker or sewing thread, use pairs of reference points on the garment 27 to 29 as a guide for the position of reference points. In 27 the position of reference points for a pair of pants is shown. In 28 the position of reference points for shirts, blouses and sweaters is shown. In 29 is the position of reference points for dresses and skirts shown. The datums generally extend from a portion of the garment to the corresponding opposing portion of the garment (eg, from the underside of the pant leg to the top of the pant leg). The exact position of each datum is not important, as the dimensional change of the garment is measured rather than the absolute dimensions of the various parts of the garment. Typically, the selected landmarks represent an integer (eg, inches or centimeters) rather than a number and a fraction of a number. However, each reference point must be at least 2.5 cm (one inch) inward from all edges or seams.
• 5. If the garment in the attempt to attach the reference points, slipping or shifting will, the garment Lay flat on a board and with needles or tacks on the board Fix board without stretching the fabric.
• 6. The distance between each pair of markings on the next Millimeter or the next Measure and record sixteenths of an inch accurately. These distances up Log a sheet of paper in a column labeled "A".

Washing / drying instructions:

• 1. No more than two garment wraps under standard washing conditions in the above washing machine lay.
• 2. The water temperature to 16 ° C (60 ° F), move to Extra Delicate (Kenmore Series 90) and the cycle setting to "6 minute Ultra Clean ".
• 3. Adjust the water level to 64 l (17 gallons) (Medium at Kenmore series 90) and start the machine. Select a single rinse.
• 4. Add product.
• 5. Once the last spin is complete is finished, remove the roll from the machine and place it on a flat surface.
• 6. Unwind the wraps, remove the clothes and dry as follows: - at Rayon and rayon / acetate fibers: in the dryer at low heat 5-10 Dry for a few minutes and then hang up to complete drying; - for silk fibers: in the dryer without heat (crease protection) Dry for 10 minutes and then hang to complete drying; and - for wool fibers: lay flat or dry hanging.

Measurements and Rating:

• 1. After completing the shrinkage test each clothing for at least 4 hours in a controlled environment (21 ° C (70 ° F), 65% relative humidity) by hanging on a hanger condition. If a garment usually not on a hanger hanged will, the garment on Put a sieve of a conditioning rack.
• 2. After conditioning every garment without Put tension on a flat, smooth, horizontal surface. If the garment is heavily wrinkled and can not be laid flat, the garment on one Fix board without stretching the fabric.
• 3. Measure the distance between each pair of markers - these log in a column labeled "B." Small folds should be be flattened with the ruler.
• 4. Calculate the dimensional change for each item on the garment: % DC = 100 (B - A) / A where DC = dimensional change A = average original dimension B = average wet cleaning size Both the original dimension (A) and the final dimension (B) are the average values of measurements at each position made on the three test garments.
• 5. For every type of fabric and garment the average dimensional change for every position on the garment to log.

Shrinkage test method - fabric sample

This Method is used to make and evaluate patterns for measuring the substance shrinkage applied.

definitions:

dimensional change (Dimensional Change, DC) - Changes the fabric length or width. expressed as a percentage of the initial ones Dimension of the fabric.
