Description

Towel Product {TOWEL PRODUCT}

The present invention relates to a terry product, which itself consists of a fabric base and a pile associated with the fabric substrate in a known manner.

Terry products are fabrics with a special absorbent and pleasant feel, especially those used in household textiles and sporting goods. Piles associated with textile substrates, in particular in the form of yarn loops, such as, for example, fabrics, are characteristic of terry products.

For the purposes of the present invention, the term “terrier product” specifically means, but is not limited to, products such as terry cloth, velour terry products, milled terry products, and twisted terry products. Does not.

Terry products, such as towels, must be specifically tailored to particular needs in terms of flexibility, absorbency and bulkiness and bulk stability (when stored, the stack of towels should not weigh down on their own weight).

Currently, commercially available terry products consist essentially of cotton. Towels made of cotton exhibit the required bulk, bulk stability and absorbency.

However, to achieve the required product flexibility, cotton products must be provided with a plasticizer. For cleaning at home, the use of fabric softeners is necessary. Both plasticizers and fabric softeners may cause allergies. Moreover, the plasticizer substantially reduces the absorbency and absorption rate of the product in which the plasticizer is provided.

Without the use of plasticizers and fabric softeners, terry products made from conventional modal fibers have lower bulk and bulk stability than products made from 100% cotton, while also having flexibility and absorbency.

Terry products comprising a mixture of cotton and conventional modal fibers have sufficient bulk as well as flexibility and absorbency, but do not exhibit sufficient bulk stability.

Terry products made from synthetic fibers (eg micropolyesters) are flexible but must be provided with hydrophilic chemicals to have sufficient absorbency.

It is an object of the present invention to provide a terry product which satisfies the needs for the fabric in a good manner without exhibiting the disadvantages of conventional products as described above.

The object is that the substrate and / or pile comprises at least partially cellulose fibers selected from the group consisting of viscose fibers, modal fibers, polynosic fibers and lyocells, wherein the cellulose fibers comprise from 1.7 dtex to It is achieved by a terry product characterized by having a titer of 4.5 dtex.

Surprisingly, when terry products use "artificial" cellulose fibers in the specific titer range of 1.7 dtex to 4.5 dtex, i. The inventors have found that excellent bulk stability is exhibited.

For example, the absorbency is improved compared to existing products including modal fibers with low titers or mixtures of cotton and modal fibers with low titers, respectively. In a preferred embodiment, fibers having a modified cross section, in particular fibers having a multilobal cross section, are used because the absorption rate and the absorbency are further improved as the fiber surface is increased. Trilobal cross sections are particularly preferred. "Man-made" cellulose fibers with multi-local cross-sections are described, for example, in patent documents EP 0 301 874 A1 and WO 2006/060835.

Preferably, the titers of the cellulose fibers used according to the invention range from 2 dtex to 4.5 dtex, particularly preferably from 2.2 dtex to 3.3 dtex, most preferably from 2.5 dtex to 2.8 dtex, especially from 2.5 dtex to 2.6 dtex range.

Particular preference is given to using modal fibers in the aforementioned titer range.

The term "modal fiber" is a generic term and, according to the definition by the International Bureau of International Standardization of Artificial Fibers (BISFA), has limited wet strength and also limited high wet modulus (i.e., 5% of the fiber in the wet state). Cellulose fiber with the force required to expand).

Due to the flexibility of the modal fibers, not only plasticizers are required in the production, but also no fabric softeners are required in the use of the terry product according to the invention.

In the terry articles according to the invention, the cellulose fibers used may be provided as cellulose staple fibers having a cut length of 30 mm to 60 mm, preferably 38 mm to 51 mm.

Cellulose fibers may be in the form of yarns or twisted yarns made therefrom. Examples of the yarn include, for example, ring spun yarn, SIRO-yarn, core-spun yarn, compact yarn, in a mixture with polyvinyl alcohol (PVA) -fiber and -yarn. Forms known per se, such as OE-yarns, airjet yarns, chenille yarns, looped yarns, and zero-twist yarns, are conceivable.

In terry products according to the invention, the cellulose fibers are cotton, polyester, wool, polytetrafluoroethylene (PTFE), polypropylene (PP), polyamide (PA), polyacrylic (PAC), polyvinyl alcohol (PVA ), Linen, silk or viscose fibers, polynostic fibers, lyocell fibers and, for example, a mixture with a fibrous material selected from the group consisting of modal fibers with a lower titer range.

Particularly advantageous are mixtures of modal fibers and cotton in the titer range.

In a preferred embodiment, the fabric substrate and / or pile are each composed essentially of cellulose fibers or a mixture comprising cellulose fibers. This means that a second component, such as yarn from cellulose fibers or blended yarns and cotton, is used in the production of the substrate and / or pile.

The proportion of cellulose fibers in the substrate and / or pile is advantageously in the range from 1% to 100%, preferably from 10% to 100%, particularly preferably from 30% to 100%.

Particular preference is given to mixtures of modal fibers 30% to 50% and cotton 70% to 50%, for example mixtures of modal fiber 30% / cotton 70% or modal fibers 50% / cotton 50%. As mentioned above, this mixture may be used for the material of the pile and / or the material of the backing fabric.

In a possible embodiment, the pile is simply composed entirely of cellulose fibers or comprises a mixture with different fibers and the substrate is composed of different fibrous materials. For example, it is advantageous to have a substrate made of 100% cotton, and a mixture of 50% modal fiber and 50% cotton and 50% modal fiber.

In another embodiment, both the pile and the substrate consist essentially of cellulose fibers or comprise a mixture with different fibers. It is advantageous if both the substrate and the pile 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.

In yet another embodiment, the substrate is comprised of either 100% cotton or 100% modal fibers. The pile consists of two threads: a thread made of 100% modal fibers and a thread made of 100% cotton. With this configuration, weaving with particular emphasis on modal fibers or cotton, respectively, is possible depending on the pattern. For piece dyeing with selected dyes, portions of cotton and modal fibers are different in terms of shade and color depth (eg Jacquard effect), respectively. Instead of cotton, for the second thread, polyester, wool, polypropylene, polyamide, polyacrylic, polyvinyl alcohol, linen, silk, viscose, polynosic and lyocell and / or mixtures thereof may be used.

In the terry product according to the invention, the pile is preferably composed of yarn loops, as is known per se, or of shorn yarn loops, as in the case of velor goods.

The fabric substrate is preferably selected from the group consisting of woven fabrics, warp-knitted fabrics, knitted fabrics and stitch-knitted fabrics.

Terry products according to the invention are preferably towels, beach towels, bath towels, sauna towels, bathrobes, cloths, bathroom carpets, tea towels, beddings, for example bed linens, mattresses And a blanket cover and a mattress support, infant clothing, sportswear, socks, lining material and a diaper, in the form of or as an ingredient thereof.

Example 1:

The warp of the substrate is composed of 100% cotton yarn (Ne 23.5 / 2 or Ne 12/1), and the weft is also composed of 100% cotton yarn (Ne 16.5 / 1). For piles, blended yarns made of 50% modal fibers (2.5 dtex, cut length 38 mm) and 50% cotton (Ne 16.5 / 1) are used. The finished product shows good absorbency, high bulk and good bulk stability. The product made from it is inherently flexible and pleasant to the touch. The finishing with plasticizers is not necessary, but in fact has the adverse effect since the absorbency and the rate of absorption are clearly reduced.

Example 2:

The inclination of the substrate is composed of 100% of cotton yarn (Ne 23.5 / 2 or Ne 12/1) as in Example 1, and the weft yarn is composed of 100% of cotton yarn (Ne 16.5 / 1). For piles, a yarn mixture of 88% modal fibers (2.5 dtex, cut length 51 mm) and 12% PVA (Ne 12 zero-twist yarn) is used. Upon further processing of the product, the PVA fibers are extracted, as a result of which the weight of the product is reduced. The finished product exhibits good absorbency and very high volume of looped yarns. As a result of the use of 2.5 dtex modal fibers with a cut length of 51 mm, the fiber bonding in the looped yarns is improved, such that the towels have much less fiber loss when used compared to towels (comparative) made from cotton-made zero-twist yarns. little.

Example 3:

The inclination of the substrate is composed of 100% cotton yarn (Ne 23.5 / 2 or Ne 12/1), and the weft yarn is also composed of 100% cotton yarn (Ne 16.5 / 1). For piles, 50% modal fibers (2.5 dtex, 38 mm cut length) and 50% cotton (Ne 16.5 / 1) with trilobal cross sections are used. The finished product exhibits good absorbency, high bulk and good bulk stability. The product made from it is inherently flexible and pleasant to the touch. A plasticizer finish is not necessary, but in fact has the adverse effect since the absorbency and the rate of absorption are clearly reduced. Bulkness, bulk stability, absorption rate and water absorption are much improved compared to Example 1.
