Definitions

• the present invention relates to a flat sponge fabric for absorbing water or other liquid in general.
• the object of the present invention furthermore relates to a procedure for manufacturing f a flat sponge fabric for absorbing water or other liquid in general.
• Flat sponge fabrics are used for the production and manufacture of bath linen such as, for example, bathrobes, facecloths, flannels and/or towels, and children's and sports clothing, or cloths for cleaning.
• the above-mentioned flat sponge fabrics are usually made up of a first and a second warp which extend substantially parallel to each other, and a weft which intersects said warps perpendicularly.
• the first warp, together with the weft, constitutes the skeleton of the flat sponge fabric, while the second warp constitutes a layer with curls intended for retaining water.
• the second warp is woven into the weft in such a way as to form a plurality of loops and curls which project outwards.
• the yarns used for forming flat sponge fabrics are normally made of cotton. These yarns are produced by spinning: a treatment process which joins the individual fibres of cotton by means of twisting them to keep them united.
• the layer with curls can be of single or double configuration.
• a layer with curls in simple configuration has a plurality of curls arranged on one side only of the fabric, while a layer with curls in double configuration has a plurality of curls arranged on both sides.
• the capacity for absorbing water depends on the quantity of cotton present and is greater in relation to the number and density of the curls in the flat sponge fabric, and for this reason the layer with double configuration has a water absorption capacity greater than that of the layer with single configuration .
• flat sponge fabrics made using cotton yarns have general characteristics that depend on the intrinsic characteristics of the yarn used.
• the flat sponge fabric has, overall, a weight per unit length that depends directly on the significant weight of the cotton yarn, which is used both for the warps and for the weft.
• the cotton yarn used for the second warp i.e. for the warp that constitutes the layer with curls, has a considerable thickness which consequently determines the overall dimensions of the second warp as well as of the flat sponge fabric itself .
• cotton yarn limits the durability of the curled layer because the second warp is not capable of effectively resisting the mechanical stresses to which the flat sponge fabric is normally subjected during use.
• the fabric described in said document does not provide for any cotton warp thread, which advantageously confers on the fabric which is the subject of the present invention characteristics which overcome the disadvantages of known flat sponge fabrics.
• the present invention provides for a light and absorbent flat sponge fabric.
• the flat sponge fabric according to the present invention, has contained dimensions.
• the flat sponge fabric subject of the present invention is durable over time.
• the flat sponge fabric according to the present invention has also high resistance to mechanical stresses .
• the flat sponge fabric according to the present invention endows bath linen and children's and sports clothing with excellent wearability.
• the second warp of the flat sponge fabric according to the present invention is made with a cotton-cut synthetic yarn, i.e. a yarn in which the individual fibres are held together by twisting .
• the cotton-cut synthetic yarn is made of polyester.
• the cotton-cut synthetic yarn preferably of polyester, of which the second warp is composed, is sized, in particular with a sizing concentration comprised between 1% and 9%, preferably comprised between 1% and 6%, more preferably comprised between 1% and 3%.
• the first warp of the flat sponge fabric i.e. the warp which together with the weft constitutes the support structure of the fabric, is made with double-twisted cotton yarn, i.e. with a yarn consisting of two or more threads of cotton rolled together.
• the present invention also provides for a procedure for the manufacture of a flat sponge fabric for absorbing water or other liquid in general, whose phases are as follows: forming by weaving a first warp using a cotton yarn; forming by weaving a second warp substantially parallel to said first yarn; forming by weaving at least one cotton weft.
• the formation of said weft causes the interweaving of the latter with said second warp to form a plurality of curls for absorbing water.
• the step of formation of said second warp is executed using a cotton-cut type synthetic yarn, preferably made of polyester.
• such a synthetic fibre yarn preferably polyester
• a sizing concentration comprised between 1% and 9%, preferably between 1% and 6%, more preferably between 1% and 3%.
• Another advantageous aspect of the present invention is that of subjecting the flat sponge fabric to a stage of bleaching which has the object of eliminating the impurities and the sizing agent.
• a further advantageous aspect of the present invention is that of subjecting the flat sponge fabric to a dyeing stage.
• This dyeing can be double with a single bath, or with a double bath.
• Figure 1 shows a sectional view of the fabric which is the subject of the present invention
• letter "A” indicates a fabric which is the subject of the present invention, comprising a first warp (1) made with a plurality of cotton yarns, a second warp (2) made with a plurality of synthetic yarns and a weft (3) made with a plurality of cotton yarns.
• the first warp (1) and the weft (3) constitute the loadbearing structure of fabric (A) , which provides a second warp (2) substantially parallel to the first warp (1), adapted to form an outer layer of the sponge fabric (A) .
• Said second warp (2) consists of a plurality of cotton- cut synthetic yarns, made particularly rough by the twisting of the textile fibres which constitute them.
• Each synthetic yarn which composes the second warp (2) is advantageously sized in a suitable manner such as to reduce its slipperiness .
• each synthetic yarn (2) preferably made of polyester, is sized with a sizing concentration comprised between 1% and 9%, preferably comprised between 1% and 6%, more preferably comprised between 1% and 3%.
• the sponge fabric (A) comprises furthermore a weft (3) made of cotton and interwoven with the second warp (2) to form a plurality of curls or loops intended for the absorption of water and similar liquids.
• the weft (3) and the second warp (2) form an outer layer with curls in simple configuration, wherein the curls project outwards from the load-bearing structure of the fabric on a single face.
• FIG 2 shows another embodiment of the fabric subject of the present invention.
• the weft (3) and the second warp (2) define an outer layer with curls in double configuration wherein the curls project outwards from the load-bearing structure of the fabric (A) at the location of both faces of said fabric.
• the above-mentioned flat sponge fabric (A) is advantageously manufactured by means of a procedure which comprises a stage of forming said first warp (1) by weaving, using at least one cotton yarn.
• the procedure comprises furthermore a stage of forming by weaving the second warp (2), positioned substantially parallel to the first warp (1) .
• the second warp (2) is made using a cotton-cut type synthetic fibre yarn preferably made of polyester.
• the procedure also comprises a stage of the weaving of at least one weft (3) in cotton.
• the formation of the load-bearing structure of the fabric is executed by interweaving the weft (3) with the first warp (1).
• the formation of the layer with curls intended for absorbing water or liquids in general is achieved by interweaving the weft (3) with the second warp (2) .
• warp (2) In order to allow the curls to be created, warp (2) must not be slippery. For this reason the synthetic yarn used for such a warp (2) must be of the cotton-cut type.
• said yarn is advantageously subjected to at least one stage of sizing, known to a person skilled in the art.
• the stage of sizing the yarns constituting warp (2) in polyester is performed using a sizing concentration comprised between 1% and 9%, preferably a sizing concentration comprised between 1% and 6%, more preferably comprised between 1% and 3%.
• said fabric preferably undergoes a stage of bleaching which has the object of eliminating the impurities and the sizing agent previously applied at least to the synthetic yarns of warp (2) .
• fabric (A) there should be at least 18 beat-ups per centimetre in the direction of the weft and/or at least 23 weft threads per centimetre .
• the thread count of the yarns used for the curls of fabric (A) is between 30NeC and 50NeC, preferably 40 NeC, i.e. between 50 NM and 84 NM, preferably 68 NM (if this is to be expressed in denier, the thread count of the yarns used for the curls of fabric (A) is between 120 and 182), preferably 135 denier) .
• the yarns used for the first warp are double-twisted and have an NeC count comprised between 20/2 and 40/2, preferably 30/2. Or, if expressed in NM, between 16 and 23,5, preferably 25 NM. if it is expressed in denier, between 270 and 540, preferably 360 denier.
