Description

Towel products {TOWEL PRODUCT}

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

Terry products are fabrics with special absorbency and pleasant feelings, especially fabrics used in household fabrics and sporting goods. For example, files associated with fabric substrates, particularly in the form of yarns (especially in the form of yarn loops), are characteristic of terry products.

For the purposes of the present invention, the term "terry product" refers specifically to a product such as terry cloth, velor terry product, milled terry product and twisted terry product, .

Terry products, such as towels, must be tailored to specific needs, particularly in terms of flexibility, absorbency and bulkiness and bulk stability (when stored, the stack of towels should not settle flat due to their weight).

At present, commercially available terry products consist essentially of cotton. Cotton made towels exhibit the required bulkability, bulk stability and absorbency.

However, in order to achieve the required flexibility of the product, the plastic article must be provided with a plasticizer. For household cleaning, the use of fabric softening agents is required. Both plasticizers and fabric softeners are likely to cause allergies. Moreover, plasticizers substantially reduce the absorbency and absorption rate of the products to which the plasticizer is provided.

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

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

Terry products made of synthetic fibers (for example, micro-polyesters) are flexible, but hydrophilic chemicals must be provided to provide sufficient absorbency.

It is an object of the present invention to provide a terry product which does not exhibit the disadvantages of prior art products as described above but is suitable for the need for the fabric in a good manner.

The object is achieved, at least in part, by the fact that the substrate and / or the pile at least partially comprise a cellulose fiber selected from the group consisting of viscose fibers, modal fibers, polynosic fibers and lyocell, Lt; RTI ID = 0.0 > dtex. ≪ / RTI >

Surprisingly, the use of "artificial" cellulosic fibers, namely viscose fibers, modal fibers, polonic fibers and lyocell fibers, in the specific titer range of 2.5 dtex to 4.5 dtex in the Terry products, The present inventors have found that they exhibit excellent bulk stability.

For example, the absorbency is improved compared to conventional products, each containing a mixture of modal fibers with low ties or modal fibers with low ties, respectively. In a preferred embodiment, fibers with a modified cross-section, especially fibers with a multilobal cross-section, are used because the absorption speed and absorbency are further improved as the fiber surface is increased. A trilobal cross section is particularly preferred. "Artificial" cellulosic fibers with a multibranched cross section are described, for example, in patent documents EP 0 301 874 A1 and WO 2006/060835.

Preferably, the titer of the cellulose fibers used according to the invention is in the range from 2.5 dtex to 4.5 dtex, particularly preferably from 2.5 dtex to 3.3 dtex, most preferably from 2.5 dtex to 2.8 dtex, in particular from 2.5 dtex to 2.6 dtex range.

It is particularly preferred to use modal fibers of the aforementioned titer range.

The term "modal fiber" is a generic term that, according to the definition by BISFA (Bureau of International Standardization of Synthetic Fibers), has a limited wet strength and also a limited high wet modulus Quot; refers to a cellulose fiber having the force necessary to expand it.

Because of the flexibility of the modal fibers, plasticizers are not required during manufacture, nor are fabric softeners required when using the terry products according to the present invention.

In the terry products according to the present 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.

The cellulosic fibers may be in the form of yarns or twisted yarns made therefrom. Examples of the yarn include a ring spun yarn, a SIRO-yarn, a core-spun yarn, a compact yarn, and a yarn in a mixture with, for example, polyvinyl alcohol (PVA) It is possible to consider a form known per se such as OE-yarns, air jet yarns, chenille yarns, loop yarns, and zero-twist yarns.

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

Mixtures of modular fibers and faces of the titer range are particularly advantageous.

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

The proportion of the cellulose fibers in the substrate and / or ply is advantageously in the range of 1% to 100%, preferably 30% to 100%, particularly preferably 50% to 100%.

Mixtures of 30% to 50% modal fibers and 70% to 50% modal fibers, respectively, for example 30% modal fibers / 70% cotton or 50% modal fibers / 50% cotton are particularly preferred. As described above, such a mixture can be used for the material of the pile and / or for the material of the backing fabric.

In possible embodiments, the file simply consists essentially of cellulosic 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 pile of 100% modal fiber or 50% modal fiber and 50% cotton.

In yet another embodiment, both the file and the substrate are essentially entirely composed of cellulose fibers or comprise a mixture with different fibers. It is advantageous if both the substrate and the file are made of 100% modal fibers, or a mixture of 50% modal fibers and 50% cotton or 70% modal fibers.

In another embodiment, the substrate is comprised of either 100% cotton or 100% modal fibers. The file consists of two threads: threads made of 100% modal fibers and threads made of 100% cotton. With such a configuration, it becomes possible to perform woven fabrics having particular focus on modal fibers or faces, respectively, depending on the pattern. In the case of piece dyeing using selected dyes, the areas of the surface and modal fibers are different in terms of shade and color depth (e.g. Jacquard effect), respectively. For the second thread, polyester, wool, polypropylene, polyamide, polyacrylic, polyvinyl alcohol, linen, silk, viscose, polynosic and lyocell and / or mixtures thereof may be used instead of the faces.

In a terry product according to the present invention, the pile preferably consists of a yarn loop, as is known per se, or a shorn yarn loop, 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.

The terry product according to the present invention is preferably a towel, a beach towel, a bath towel, a sauna towel, a yukata, a cloth, a bathroom carpet, a tea towel, a bedding, And blanket cover and mattress support, infant clothing, sportswear, socks, lining materials and diapers.

The present invention provides a textile substrate that exhibits excellent bulk performance as well as good bulk stability and a terry product comprising a pile associated with the substrate.

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 made up of 100% cotton yarn (Ne 16.5 / 1). For the file, a blended yarn made of 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 bulk and excellent bulk stability. Products made from them are inherently flexible and have a pleasant feel. Finishing with a plasticizer is not required, but it has adverse effects because the absorbency and the rate of absorption are obviously reduced.

Example 2:

The slope of the substrate is made up of 100% of cotton yarn (Ne 23.5 / 2 or Ne 12/1) in the same manner as in Example 1, and the yarns are composed of 100% cotton yarn (Ne 16.5 / 1). For the file, a mixture of yarns of 88% modal fiber (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 fiber is extracted, resulting in a reduction in weight of the product. The finished product exhibits excellent absorbency and very high volume loopy yarns. As a result of using 2.5 dtex modal fibers with a cutting length of 51 mm, fiber bonding in the loop type yarns is improved, so that such towels have much less fiber loss in use compared to towels made from cotton-made zero-twist yarns little.

Example 3:

The inclination of the base material 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 the file, 50% modal fibers with a triplet cross section (2.5 dtex, cut length 38 mm) and 50% cotton (Ne 16.5 / 1) are used. The finished product exhibits excellent absorbency, high bulk and excellent bulk stability. Products made from them are inherently flexible and have a pleasant feel. Finishing with a plasticizer is not required, but has adverse effects because the absorbency and the rate of absorption are obviously reduced. The bulk stability, the bulk stability, the absorption rate, and the absorbency are much improved as compared with Example 1.
