Description

The cleaning system of laundering of textile fabrics

Technical field

The present invention relates to a kind of cleaning system of laundering of textile fabrics.Cleaning system of the present invention is generally embedding a kind of expansion of cleansing bar in fluffy body/sponge.

Background and prior art

In the general operation that utilizes the detergent bar laundering of textile fabrics, embrocate fabric with soap bar earlier, wipe with the brush brush back, removes the spot and the dust of staining on the fabric.By elder generation's standard wash soap bar rubbing effect, the method that the back rubs with hard object, cleaning performance is satisfactory.

In the detergent bar prescription, the general non-soap surfactant that adopts, its detergency is strong, but the deficiency that spumes.Even it has produced foam, but also thin and lack emulsus because of it, and make human consumer's sensory quality inferior.Foam volume and quality are considered to an important parameter, and be relevant with its clean-up performance.The human consumer trends towards firmly producing foam in washing process, and only otherwise produce gratifying foam, the human consumer also tends to apply more products.

As everyone knows, adopting conventional soap bar and scouring method laundering of textile fabrics is effectively, but adopts this hand washing method, can make fabric abrasion very big, thereby shorten the life-span of fabric.It has also caused some common problems, and such as the washing composition loss, washing composition uses irregular, thereby has increased the soap bar wear rate, causes it uneconomical.

Known have the various cleaning systems that comprise soap to be used to clean skin:

International monopoly bulletin WO 95/00116 has proposed to comprise the system of hydrophobicity sponge.This piece document belongs to hand-held sponge and a kind of gentle frothed liquid made by the hydrophobic synthetic materials of a kind of diamond-shaped meshes and cleans a kind of combination that Wetting composition constitutes specially at a kind of cleaning system that is used for cleaning skin.

US 5462378 has proposed a kind of the shower and has kept the motionless bath towel of detergent bar when using.This bath towel is made by a kind of continuous tubulose elastic woven material, and this elastic woven material is cut into predetermined length, and opening end is sewn together, constitutes the inner bag that can place soap.To use inconvenience among shower process and the shower be the trouble of detergent bar slippage in order to overcome, and prevent that soap bar from contacting deliquescing with water in the soap dish, proposed this bath towel.

US 4480939 relates to the soap holder and the dispensing device of a kind of suitable shower setting and use.This soap holder and dispensing device comprise a box of being made by synthetic net materials, and the suspension hook that it can hold a soap bar and a band pawl can support the box in the shower.Be to prevent soap loss in the soap dish according to this soap holder of this patent and dispensing device purpose, assurance shower soap bar is used up entirely, and soap is received and distributed easily.This dispensing device uses the usefulness of soap for shower and other shower occasion.

US 4190550 relates to the soap filling pad that the seamless fiber is made, and the skin of people in the shower process is had cleaning and the gentle effect of strengthening friction.

European patent application EP 0863201 A2 relates to a kind of soap bar in fluffy body/sponge, is used to strengthen foam, and relates to minimizing powder paste sensation.It is favourable that soap bar is placed on fluffy body, because it has hormesis to skin, and receives and distributes easier.

All above-mentioned documents relate to perfumed soap and soap bar, but wherein none is mentioned and the relevant problem of the used detergent bar of fabric washing.

The invention summary

The applicant finds, uses in light weight, places a kind of cleaning system of cleansing bar in the hand-holdable polymkeric substance mesh sponge, can solve above-mentioned and the problem that runs into the detergent bar clean textile.Confirm now, adopt according to this system of the present invention that foam is formed obviously increase, cleaning performance is better, the detergent bar abrasion reduce and powder is stuck with paste and alleviated, and wash firmly little, thereby little to fabric abrasion.Washing operation is gentle to skin, because this detergent bar does not directly contact with skin.Need not to use brush or scrubber.

Detailed Description Of The Invention

Therefore, the present invention relates to a kind of cleaning system of laundering of textile fabrics, comprise a kind of fabric washing soap bar and a kind of polymkeric substance mesh sponge that grabs in hand in light weight, described sponge is fit to soap bar is placed in its internal cavity, so that when using this soap bar is encapsulated in the sponge, and in washing process by fluid/foam and sponge external communications and contact fabric.This area also is referred to as fluffy body (pouf) to this lightweight polymkeric substance mesh sponge.

In the clean operation process, soap bar is installed in the cavity of sponge/fluffy body.Adopt and the exposed soap bar the same manner of wiping, on wet fabric, wipe the fluffy body of dress soap bar in this.Fluffy body was not used before clean textile.In addition, being used in combination of soap bar and fluffy body constituted a kind of collaborative cleaning action and other exceeds and be better than using separately those advantages that they obtained.

The fabric washing soap bar

Expert group's evaluation:

Make evaluation by expert group to the conventional washing methods that uses detergent bar and brush with at sense of touch and clean-up performance that this detergent bar is embedded into when using in the fluffy body.

Following determined property is estimated.

1, product dosage/wiping:

Wipe 1,2 and 3 time in the staining fabric wiping with the detergent bar in detergent bar and the fluffy body of embedding, measure according to detergent active on it, calculate the product quantity that is passed on this fabric.

2, formation of foam/wiping:

With detergent bar with embed detergent bar in the fluffy body and on staining fabric, wipes and wipe 1,2 and 3 time, wipe same number of times with the brush wiping.Water sweeps away in foam to a graduated cylinder, measures to form volume of foam.

3, detersive power:

Adopt Milton Roy Match Scan II instrument, scan, be chosen at 460nm place reflectance value mensuration detergency to staining fabric with detergent bar and the staining fabric that embeds after the detergent bar washing in the fluffy body.Calculate detergency %.

Table 2

Number of times is wiped in wiping	Conventional washing			With the soap bar washing that is closed in fluffy body
								Foam (milliliter)	Product (gram)	Detergency %	Foam (milliliter)	Product (gram)	Detergency %
????1	????60	????0.33	????77.5	????65	????0.15	????71.9
							????2	????65	????0.46	????80.0	????70	????0.19	????75.9
????3	????65	????0.62	????78.8	????75	????0.25	????77.5

The listed data of table 2 show, detergent bar is embedded in the fluffy body, have avoided the loss of product, show that also the foam volume of the product generation of using relatively low-levels is significantly higher, to but not influence of detergency.

The soap bar evaluation shows that this system grips easier to soap bar, and wearing and tearing and powder are stuck with paste speed and significantly reduced.

Therefore, soap bar embedded possess following advantage in the fluffy body:

1, form significantly higher foam, it is less to require great effort, and the product consumption is less.

2, soap bar wearing and tearing and powder are stuck with paste and are reduced

3, the loss of soap bar detritus reduces

4, soap bar clamping property improvement

5, can add a rope handle to the soap bar in the fluffy body, so that fesloon drying.

6, need not to use brush or scrubber.

This fluffy body is lower to the fabric adstringency, is conducive to prolong fabric life.

Can adapt to the detergent bar that any standard forms that has known in the art with fluffy intracoelomic cavity.
