Description

TOWEL PRODUCT DESCRIPTIVE MEMORY The present invention relates to a towel cloth product consisting, in a manner known per se, of a textile base material and a plush related to the base material. Towel cloth products are textile articles with a particular absorbency and a pleasant sensation, which are used, in particular, in the fields of home textiles and sporting goods. Plush (particularly in the form of loops of yarn) that relate to a textile base material, eg, a fabric, is characteristic of towel cloth products. For the purposes of the present invention, the term "towel cloth product" covers especially but not exclusively products sas towel cloth, velvety terry cloth products, pledget cloth products and twisted towel cloth products. Towel cloth products, for example, towels, have to meet specific demands especially in terms of their softness, their absorbency, their volume and their volumetric stability (during storage, a stack of towels should not sink under their own weight ). At present, commercially available towel cloth products consist essentially of cotton. The towels made of cotton have the required volume, volumetric stability and absorbency. However, in order to achieve the required softness of the product, the cotton products must be finished with a plasticizer. For washing at home, the use of fabric softeners is necessary. It is thought that both the plasticizer and the fabric softeners are allergenic. In addition, plasticizers substantially reduce the absorbency and absorption rate of finished products therewith. Without the use of plasticizers and fabric softeners, towel cloth products made with conventional modal fibers are soft and also absorbent but have a lower volume and lower volume stability than products made with 100% cotton. Towel fabric products comprising a mixture of cotton and conventional modal fibers are soft, absorbent and have sufficient bulk but do not have sufficient volumetric stability. Towel cloth products made of synthetic fibers (eg, micropolyester) are soft but must be finished with hydrophilic chemicals in order to achieve sufficient absorbency. It is the object of the present invention to provide towel cloth products that meet the demands made on said textile articles in an excellent manner without presenting the aforementioned drawbacks of prior art products.

Said objective is achieved with a towel cloth product characterized in that the base material and / or the plush comprise at least partially a cellulose fiber selected from the group consisting of viscose fibers, modal fibers, polynomial fibers and lyocell, whose cellulose fiber has a linear mass of more than 1.7 dtex to 4.5 dtex. Surprisingly, it has been found that the use of "synthetic" cellulose fibers, ie viscose fibers, modal fibers, polynotic fibers and lyocell fibers, on a specific linear mass scale of more than 1.7 dtex to 4.5 dtex in a towel cloth product makes the products according to the invention have excellent volume and excellent volume stability. The absorbency is improved compared to existing products comprising, for example, modal fibers having a lower linear mass or mixtures, respectively, of modal fibers with a low linear mass and cotton. In a preferred embodiment, fibers with a modified cross section, in particular fibers with a multilobal cross section, are used, since the absorption speed and absorbency are further improved as a result of the elongated fiber surface. A trilobal cross section is particularly preferred. The "synthetic" cellulose fibers have a multilobal cross section as described, for example, in EP 0 301 874 A1 as well as in WO 2006/060835.

Preferably, the linear mass of the cellulose fiber used according to the invention ranges from 2 dtex to 4.5 dtex, particularly preferably from 2.2 dtex to 3.3 dtex, more preferably from 2.5 dtex to 2.8 dtex, in particular from 2.5 dtex to 2.6 dtex. The use of a modal fiber in the scale of the aforementioned linear mass is particularly preferred. The name "modal fiber" is a generic term that, in accordance with the definition of BISFA (International Association for the Standardization of Synthetic Fibers), denotes a cellulose fiber that has a high defined moisture resistance and a high wet modulus that it has also been defined (ie, the force required to expand the fiber in the wet state by 5%). Due to the softness of the modal fiber, no plasticizers are required during production, nor fabric softeners for further use in the towel cloth product according to the invention. In the towel cloth product according to the invention, the cellulose fiber used can be provided as a discontinuous cellulose fiber having a cutting length of 30 mm to 60 mm, preferably 38 mm to 51 mm. The cellulose fiber may be present in the form of a twisted yarn or yarn produced therefrom. The types known per se such as, for example, single ring threads, SIRO threads, single threads with core, compact threads, OE threads, air jet threads, worm threads, loop threads and yarns without torsion, for example , in mixture with fibers and polyvinyl alcohol (PVA) yarns, come into consideration as yarns. In a towel cloth product according to the invention, the cellulose fiber may be present in a mixture with a fiber material selected from the group consisting of cotton, polyester, wool, polytetrafluoroethylene (PTFE), polypropylene (PP), polyamide (PA), polyacryl (PAC), polyvinyl alcohol (PVA), linen, silk or also viscose fibers, polynose fibers, lyocell fibers and modal fibers having, for example, a lower linear scale of mass. A mixture of a modal fiber in the aforementioned linear mass scale with cotton is particularly useful. In a preferred embodiment, the textile base material and / or the plush consist essentially entirely of the cellulose fiber or the mixture comprising the cellulose fiber, respectively. This means that the yarns exclusively from the cellulose fiber or mixed yarns, respectively, of the cellulose fiber and a second component, for example cotton, are used for the production of the base material and / or the plush. The proportion of the cellulose fiber in the base material and / or the plush usefully ranges from 1% to 100%, preferably from 10% to 100%, particularly preferably from 30% to 100%. The mixtures of, in each case, 30% to 50% of modal fibers and 70% to 50% of cotton, for example 30% of modal fibers / 70% of cotton or 50% of modal fibers / 50% of cotton, are they prefer in particular. As mentioned above, these blends can be used in the plush material and / or the material of the backing fabric. In a possible embodiment, only the plush consists essentially of the entire fiber cellulose, or respectively, comprises a mixture with a different fiber, and the base material consists of a different fiber material. An embodiment with a base material of, for example, 100% cotton and a plush of 100% modal fibers or a blend of 50% modals and 50% cotton is useful. In a further embodiment, both the plush and the base material consist essentially entirely of the cellulose fiber or, respectively, comprise a mixture with a different fiber. A modality is beneficial where both the base material and the plush are made of 100% modal fibers or a mixture of 50% modal fibers and 50% cotton or a mixture of 30% modal fibers and 70% cotton, respectively. In a further embodiment, the base material consists of 100% cotton or 100% modal fibers. The plush consists of two yarns, mainly a yarn made of 100% modal fibers and a yarn made from 100% cotton. This construction allows itself to be woven, depending on the pattern, with the main focus specifically on modal fibers or cotton, respectively. In the case of a piece dyed with selected coloring materials, the portions of cotton and modal fibers, respectively, differ in terms of shade and depth of color (e.g., Jacquard effect). Instead of cotton, a fiber of the group comprising polyester, wool, polypropylene, polyamide, polyacryl, polyvinyl alcohol, linen, silk, viscose, polynose and lyocell and / or mixtures thereof can also be used for the second yarn. In the towel cloth product according to the invention, the plush preferably consists, as is known per se, of loops of yarn or, as with velvety articles, of loops of shorn yarn. The textile base material is preferably selected from the group consisting of woven fabrics, square mesh fabrics, knitted fabrics and knitted fabrics of the right. The towel cloth product according to the invention is preferably provided in the form of or as a component, respectively, of an article selected from the group consisting of towels, beach towels, bath towels, sauna bath towels, mantles for bath, wipes, bath mats, cloths, blankets, for example, bedding, cover for bed and blankets and mattress supports, baby clothes, sportswear, socks, lining materials and diapers.

EXAMPLES EXAMPLE 1 The warp of the base material consists of 100% cotton yarn (Ne23.5 / 2 or Ne12 / 1), the weft also consists of 100% cotton - (Ne 16.5 / 1). For plush, a mixed yarn made from 50% modal fibers (2.5 dtex, cut length 38 mm) and 50% cotton (Ne 16.5 / 1) is used. The finished product exhibits excellent absorbency, high volume and excellent volumetric stability. The article has an inherent softness and pleasant sensation. Finishing with plasticizers is not required but in fact has adverse effects since the absorbency and absorption speed are clearly reduced.

EXAMPLE 2 The warp of the base material consists, as in Example 1, of 100% cotton yarn (Ne 23.5 / 2 or Ne 12/1) and the weft consists of 100% cotton -Ne 16.5 / 1. For the plush, a yarn blend of 88% modal fibers (2.5 dtex, cutting length 51 mm) and 12% PVA (yarn without twisting Ne 12) is used. During the further processing of the product, the PVA fibers are extracted, so that the weight of the product is reduced. The finished product exhibits excellent absorbency and a very high volume of the loop yarn. Due to the bonding of the improved fiber in the loop yarn as a result of the use of a 2.5 dtex modal fiber with a cutting length of 51 mm, said towel loses much less fibers during use than a comparable towel of a yarn without twist made of cotton.

EXAMPLE 3 The warp of the base material consists of 100% cotton yarn (Ne 23.5 / 2 or Ne 12/1), the weft also consists of 100% cotton - (Ne 16.5 / 1). For the plush, a mixed yarn made from 50% modal fibers with a cross section of trilobal fiber (2.5 dtex, cut length 38 mm) and 50% cotton (Ne 16.5 / 1) is used. The finished product has excellent absorbency, high volume and excellent volumetric stability. The article has a soft and pleasant sensation inherently. The plasticizer finish is not required but in fact it has adverse effects since the absorbency and absorption speed are clearly reduced. The volume, volumetric stability, absorption speed and absorbency are improved compared to example 1.
