Description

terry

The present invention relates to a terry product which consists of a textile base body and a pile connected to the main body in a manner known per se.

Terry goods are textile articles with special absorbency and pleasant grip, which are used in particular in the home textile sector and sporting goods sector. A characteristic of terry products is the pile (in particular in the form of yarn loops) which is provided with a textile base, e.g. a tissue connected.

The term "toweling" for the purposes of the present invention includes, but is not limited to, products such as terry toweling, velor terry toweling, terry toweling, and twisted terry toweling.

Terry goods, e.g. Towels, in particular with regard to their softness, their absorbency, their bulk and their resistance to bulking (when stored a pile of towels may not collapse under their own weight) to meet special requirements.

At present, terry goods on the market are essentially made of cotton. Cotton towels have the required bulk, resistance to bulking and absorbency.

However, to achieve the necessary softness of the product, cotton products must be finished with a plasticizer. Household linen requires the use of fabric softeners. Both plasticizers and fabric softeners are suspected of being allergenic. Plasticizers also significantly reduce the absorbency and wicking speed of products so equipped.

Terry fabrics made of conventional modal fibers are soft and absorbent without the use of plasticizers and fabric softeners, but have less bulk and less resistance to bulking than 100% cotton products.

Terry products containing a blend of cotton and conventional modal fibers are soft, absorbent and have sufficient bulk, but do not have sufficient bulk-fastness. Terry products made of synthetic fibers (eg micro-polyester) are soft, but must be equipped with hydrophilic chemicals to achieve sufficient absorbency.

It is the object of the present invention to provide terry products which excellently meet the requirements imposed on such textile articles without having the above-mentioned disadvantages of prior art products.

This object is achieved with a terry product, which is characterized in that the base body and / or the pile at least partially contains a cellulose fiber selected from the group consisting of viscose fibers, modal fibers, polynosic fibers and lyocell, which has a titer of more than 1.7 dtex up to 4.5 dtex.

It has surprisingly been found that the use of "man-made" cellulose fibers, ie viscose fibers, modal fibers, polynosic fibers and lyocell fibers, in a specific titer range of more than 1.7 dtex to 4.5 dtex in a terry fabric causes the inventive Products have both excellent Bausch and Bauschbeständigkeit.

The absorbency is compared to existing products which are e.g. Modal fibers with a lower titer or mixtures of modal fibers with lower titre and cotton contained improved. In a preferred embodiment, cross-sectionally altered fibers, in particular fibers having a multilobal cross-section, are used, since the suction speed and absorbency are further improved by the enlarged fiber surface. Particularly preferred is a trilobal cross section. "Man-made" cellulose fibers having a multilobal cross-section are described, for example, in EP 0 301 874 A1 and in WO 2006/060835.

The titre of the cellulose fiber used according to the invention is preferably 2 dtex to 4.5 dtex, more preferably 2.2 dtex to 3.3 dtex, most preferably 2.5 dtex to 2.8 dtex, in particular 2.5 to 2.6 dtex ,

Particularly preferred is the use of a modal fiber in said titre range.

The term "modal fiber" is a generic term used in the definition of BISFA (Bureau for the International Standardization of Man-Made Fibers) for a cellulosic fiber with a defined high wet strength and also a defined high wet modulus (ie the force needed to stretch the fiber by 5% when wet).

Due to the softness of the modal fiber in the terry toweling product according to the invention neither plasticizer in the production nor softener in further use necessary.

In the terry toweling product according to the invention, the cellulose fiber used may be in the form of a cellulose staple fiber having a cut length of 30 mm to 60 mm, preferably 38 mm to 51 mm.

The cellulose fiber may be in the form of a yarn or a twisted yarn made therefrom. As yarns, known types such as e.g. Ring yarns, SIRO yarns, core yarns, compact yarns, OE yarns, air jet yarns, chenille yarns, loop yarns and zero twist yarns, e.g. in admixture with polyvinyl alcohol (PVA) fibers and yarns.

In the terry toweling product according to the invention, the cellulose fiber can be mixed with a fiber material selected from the group consisting of cotton, polyester, wool, polytetrafluoroethylene (PTFE), polypropylene (PP), polyamide (PA), polyacrylic (PAC), polyvinyl alcohol (PVA), linen , Silk, or viscose fibers, polynosic fibers, lyocell fibers and modal fibers with an example lower titer range.

In particular, a mixture of a modal fiber in said titre range with cotton is advantageous.

In a preferred embodiment, the textile base body and / or the pile substantially completely consist of the cellulose fiber or the mixture containing the cellulose fiber. By this is meant that for the production of the main body and / or the pile exclusively yarns of the cellulose fiber or blended yarns of the cellulose fiber and a second component, e.g. Cotton, to be used.

The proportion of the cellulose fiber on the base body and / or on the pile is advantageously 1% to 100%, preferably 10% to 100%, particularly preferably 30% to 100%.

Particularly preferred are mixtures of in each case 30% to 50% modal fibers and 70% to 50% cotton, for example 30% modal fibers / 70% cotton or 50% modal fibers / 50% Cotton. These mixtures can, as mentioned, be used in the material of the pile and / or in the material of the background fabric.

In one possible embodiment, only the pile substantially entirely consists of the cellulose fiber or contains a mixture with another fiber, and the base body consists of another fiber material. Advantageous is an embodiment with a base made of, for example, 100% cotton and a pile of 100% modal fibers or a mixture of 50% modal fibers and 50% cotton.

In a further embodiment, both the pile and the main body consist essentially completely of the cellulose fiber or contain a mixture with another fiber. Advantageous is an embodiment in which both the base body and the pile 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 a further embodiment, the base body consists of either 100% cotton or 100% modal fibers. The pile consists of two threads, namely a thread of 100% modal fibers and a thread of 100% cotton. This construction allows, depending on the pattern, to be woven specifically with a focus on the modal fibers or the cotton. When piece dyeing with selected dyes, the cotton or modal fiber content is different in hue and color depth (e.g., jacquard effect). Instead of cotton, a fiber from the group polyester, wool, polypropylene, polyamide, polyacrylic, polyvinyl alcohol, linen, silk, viscose, polynosic and lyocell or / and mixtures thereof can be used for the second thread.

In the terry toweling according to the invention, as is known, the pile preferably consists of yarn loops or, as in the case of velor goods, of shorn yarn loops.

The textile base body is preferably selected from the group consisting of woven fabrics, warp knitted fabrics, knitted fabrics and stitchbonded fabrics.

The terry product according to the invention is preferably in the form of or as part of an article selected from the group consisting of towels, beach towels, bath towels, sauna towels, bathrobes, washcloths, bath rugs, tea towels, bed linen, eg sheets, mattress and duvet covers and mattress pads, baby clothes, Sportswear, socks, linings and diapers. Examples:

Example 1 :

The chain of the basic body consists of a 100% cotton yarn (Ne23,5 / 2 or Nel2 / 1), the shot also from 100% cotton - (Ne 16,5 / 1). For the pile a mixed yarn of 50% modal fibers (2.5 dtex, cut length 38 mm) and 50% cotton (Ne 16.5 / 1) is used. The finished product has excellent absorbency, high bulk and excellent bulk fastness. The article has an inherently soft and comfortable feel. Equipment with plasticizers is not necessary, but even has negative effects, since the absorbency and suction speed are significantly reduced.

Example 2:

The chain of the main body consists as in Example 1 of a 100% cotton yarn - (Ne23,5 / 2 or Nel2 / l) and the shot of 100% cotton - Ne 16.5 / 1. For the pile, a yarn mix of 88% modal fibers (2.5 dtex, 51 mm cut length) and 12% PVA (Ne 12 zero twist yarn) is used. The P VA fibers are dissolved out in the further processing of the product, whereby the weight of the product is reduced. The finished product has an excellent absorbency and a very high volume of Schiingengarns. Due to the improved fiber incorporation in the loop yarn by using a 2.5 dtex modal fiber with a cut length of 51 mm, such a towel loses significantly less fiber in use than a comparable towel made from a cotton zero-twist yarn.

Example 3:

The chain of the basic body consists of a 100% cotton yarn (Ne23,5 / 2 or NeI 2/1), the shot also from 100% cotton - (Ne 16,5 / 1). For the pile, a mixed yarn of 50% modal fibers with a trilobal fiber cross section (2.5 dtex, cut length 38 mm) and 50% cotton (Ne 16.5 / 1) is used. The finished product has excellent absorbency, high bulk and excellent bulk fastness. The article has an inherently soft and comfortable feel. Equipment with plasticizers is not necessary, but even has negative effects, since the absorbency and suction speed are significantly reduced. Bulk, bulk, wicking, and absorbency are further improved compared to Example 1.
