Description

Household or industrial cleaning article

Technical Field

The utility model relates to a household or industrial cleaning product.

Background

Cleaning articles for industrial or domestic use (e.g. mops and fringes) are currently available on the market, the cleaning elements of which are made of strips of non-woven fabric or plied or bulky helical yarns of various sizes, weights and compositions.

However, these products have some drawbacks, for example, in the case of cleaning floor articles made of nonwoven, the cleaning efficiency is general at all points of the floor, in particular in the corner areas, due to the rigidity of the structure provided by the nonwoven.

As described in patent EP 1362544, the article made of plied or bulky helical yarns, although softer with respect to the article made of nonwoven, is not very effective due to the high degree of wear to which it is subjected, which causes a loss of the helical structure with consequent disintegration of the article, which then has to be replaced, which leads to an increase in costs.

The production of household or industrial cleaning articles comprising a soft element intended to come into contact with the surface to be cleaned, said soft element being made of a fabric of the knitted type, is also known. In particular, the fabric in the article in question is formed by a single weft or warp element made on a loom, the main production unit of which is a needle that allows the formation of a curvilinear fabric by stitches extending in the transverse direction of the weft fabric or by stitches extending in the perpendicular direction of the warp fabric. In this way, it is possible to obtain (using both weft and warp knitting machines) strips of fabric wound on a spool-shaped or reel-shaped tube and used for preparing mops, boards, fringes, brooms and other articles for cleaning.

Domestic or industrial cleaning articles of this type, although showing improvements over known articles, still have some wear problems which over time cause wear-through and similar drawbacks.

SUMMERY OF THE UTILITY MODEL

Thus, it is desirable to obtain household or industrial cleaning articles that can be effective on any surface to be treated, which articles reach every point of these surfaces and do not undergo rapid wear.

Thus, another object of the present invention is to produce a household or industrial cleaning article comprising a very light and effective material with high absorption properties, capable of cleaning any point in any surface without rapid wear.

Detailed Description

For the purposes of the present invention, the term "plait-type yarn" refers to a plait consisting of a single element, prepared using a knitting plaiter whose main production unit is a needle that allows the formation of curvilinear fabrics from stitches extending in a vertical direction.

According to the utility model discloses a structure of articles for use is including the pigtail type yarn that uses knitting plaiter production. Fig. 1 and 2 show an example of knitting a braid 10 (hereinafter referred to as braid) and an example of a round cord having a core 20 (hereinafter referred to as cored cord).

The cord forming the cleaning portion of the article described above is made using various widths of plaits or cords assembled from, for example,

plastic covers

31 and 32 as described below. This allows for a fast assembly of the articles to be produced with saved production time and costs.

Figures 7a, 7b, 7c, 7d and 7e show some elements of the production mechanism of the plait-type yarn, in which it can be noted that the thread guide 105 mounted on the disc 110 feeds the crochet 101 mounted on the tube 100 which rotates first in a clockwise direction and then in a counterclockwise direction alternately 104.

Characterized in that yarn bundles of different types of braided yarns produced using a knitting machine are produced by simultaneously moving a crochet needle 101-104 (which forms the knitting machine) and a thread 200-203 mounted on a needle tube 100. Using the present machine, a core braid made up of a plurality of yarns 204 can be prepared.

Knitted plait-type yarns are made of one or more interconnected threads running in a vertical direction with respect to the synchronous or sequential operation of the needles used. In the case of plaiting machines that use needles in sequence, the braided yarn is formed by the rotation of the tube and the single movement of the crochet needle.

To produce a cord 205 with internal reinforcement, the cord guide 109 mounted on the tray 110 has a central hole into which the bundle of reinforcement cords 204 is inserted.

Figures 7a-7e show how the stitches are formed to produce a yarn.

In fig. 7a, a tube 100

houses crochet hooks

101, 102, 103, 104 which bind the threads together by

thread guides

105, 106, 107, 108 mounted on a disc 110.

In fig. 7b, the tube 100 is rotated so that the thread is moved from the creel outside the machine onto the needle to enable the formation of the suture.

In fig. 7c, the needles are lowered to form the knuckles and yarn plaits are prepared.

In order to produce a cord with a reinforcing core 20, it is necessary to use a yarn bundle which is inserted into the cord prepared from the cord by means of a cord guide 109.

Fig. 7d and 7e illustrate the movement of the needle and tube to form a plait bundle.

The cord thus obtained using a knitting plaiter is wound on a bobbin-shaped tube, or in a box, and is used for producing mops, boards, fringes, brushes, brooms and other articles for cleaning. For the purposes of the present invention, the term "mop" refers to household and industrial cleaning products 30, as shown in fig. 3 and 4. Such an article comprises a two-part support, namely a bell 31 for receiving the handle coupling, and a fork 32 which is inserted into a special housing in the bell and which holds the fabric support forming the mop cleaning part.

For the purposes of the present invention, the term "board" refers to household and industrial cleaning articles 50, such as shown in fig. 6, which include, for example, a braid 5 attached to a flat fabric support as shown in fig. 1.

The support advantageously has two lateral pockets 51 adapted to receive plastic or metal supports to which the handle is attached. For the purposes of the present invention, the flat fabric support may be a loop-shaped Velcro fabric adapted to be coupled to a plastic or metal support to which the handle is attached.

For the purposes of the present invention, the term "beard" refers to household and industrial cleaning articles 40, such as shown in FIG. 5, which include, for example, a plurality of fabric support plaits 5 as shown in FIG. 1 or cored round cords 20 as shown in FIG. 2.

The plaits 5 or cords 20 are joined together at one or more points to form a flat piece of fabric. The flat block assembled with the relative handle allows cleaning of surfaces of large dimensions, such as the floor of a shop.

Both the plate 50 and the fringes 40 can be of the dry type, i.e. they do not require water and detergents to perform their cleaning function; or wet, which requires the use of water and/or detergents suitable for removing the dirt.

With regard to the manufacture of mop 30, yarn plaits 5 are assembled using conventional looping assembly techniques and, if desired, cut or trimmed at the free portions to form mop 30 with cut yarns.

The same process is performed to produce the fringes 40 and the plates 50 for removing dirt or solid material from the ground.

In contrast, with regard to the production of the plate 50 or the rigid fringes 40, the yarn plait 5 or cord 20 is face-stitched onto the surface of a flat textile support (such as a warp-knitted textile) by using tufting techniques or simply by stitching.

In order to prevent the loops formed by the top-stitched (topstitched) fabric as described above from being easily pulled out, a single-or double-loop fabric formed by polypropylene (PP) loops heated to a PP softening temperature after having been top-stitched or stitched and warp and weft threads made of conventional materials is also used as a flat support.

After the polymer has set, the support remains rigid and the loop formed by the strip of facing fabric remains strong due to the polymer, preventing the facing fabric from being pulled out and damaging the plate with fringes.

The rigid panel may also be formed on a Velcro receiving rigid substrate with the yarn plait stitched in strips to a smooth portion of the Velcro receiving rigid substrate to produce a soft surface including plaits suitable for cleaning large areas.

All household or industrial cleaning articles produced according to the present invention can be prepared using cut rings or looped yarn braids.

The materials used, individually or in combination, to produce the yarn plaits according to the invention are as follows, as indicated by the international abbreviation for standard DIN 60.0001:

-yarns made of natural fibres: the natural fiber is organic CO/CO, KL, LI, HA, JU, RA, SI, AB, CC, bamboo, wood fiber, fiber obtained from soybean, and corn fiber;
