Abstract

Garment knitted from phase change material (PCM) - yarn in which a paraffin core is introduced directly into cavities of a cellulose fiber during the spinning process according to the Lyocell process, the yarn being made from a mixture of wool, cellulose and polyester or another mixture with a wool component and cellulose and the cellulose has a fiber covering and a core, so that direct contact of the material in the core with the skin is avoided, characterized in that the core influences the properties of the garment, contains permethrin or lavender and pest-controlling works.

Description

Technical field

The invention relates to a knitted garment. Examples of knitted garments are jackets, sweaters, vests, dresses, skirts, pants, shirts, coats and the like. It is desirable if the knitted garment has good thermoregulatory properties, is easy to maintain and is resistant to pests.

State of the art

There are so-called PCM yarns (Phase C hange M aterial) are known in which a paraffin-grain during spinning process according to the Lyocell process of a cellulose fiber is introduced directly into cavities. If a garment is made from such a PCM yarn, heat can be stored and released again, unlike with purely insulating materials. The advantage of these yarns is that the core is also protected during washing and that a larger amount of heat can be stored per fiber volume. The yarn has the thermoregulating properties even before the garment is manufactured. This technology is usually used for cellulose or cotton fibers.

The paraffin spun in can be modified so that the phase transition takes place at different temperatures Ts. In this way, heat can be absorbed or released at different temperatures. The phase transition young temperatures are typically between 20 ° C and 50 ° C.

Wool also has good thermoregulating properties. A disadvantage of using yarns from wool is that they are susceptible to pests, such as clothes moths.

DE 102 08 199 A1 (Terra) discloses the use of microcapsules with a vaporizable active ingredient in a textile for controlling pests.

DE 10 2009 045 465 A1 (NanoSky.com AG) discloses the use of permethrins as a pesticide. The agent is used to impregnate wool.

US 2007/0148449 A1 discloses military camouflage clothing in which yarns can be provided with anti-microbiological, anti-static and odor-inhibiting agents and then treated with an insecticide. The agent is a metal coating that is applied to the outside of the thread.

JP 2307901 A discloses knitted socks with anti-microbiological and anti-odor properties. The socks are knitted from two different yarns in two layers. The yarns disclosed are homogeneous and some of the yarns contain a copper compound (copper sulfate).

US 2006/0277950 A1 discloses clothing with phase change material. The use of anti-microbial properties is also disclosed to prevent odors.

EP 1 788.130 A1 discloses an antimicrobial knitted fabric. Antimicrobial is defined as "killing germs, bacteria, viruses or fungi". Accordingly, antimicrobial agents, namely metallic coatings, are disclosed.

EP 2 264 231 A1 discloses yarns with a core of phase change material, which is provided with antimicrobial additives.

JP 2002 317 329 A discloses the use of heat accumulation material in synthetic fibers.

DE 699 11 899 T2 discloses a composite textile made of synthetic fibers with antimicrobial properties.

A wool yarn impregnated with pesticide has the disadvantage that the pesticide washes out after some time. The pesticide also has direct contact with the skin. That is undesirable.

Disclosure of the invention

1. (a) ein Garn mit einem Kern aus einem Material verwendet wird, das die Eigenschaften des Kleidungsstücks beeinflusst,
2. (b) dass das Kleidungsstück aus Garn besteht, das einen Wollanteil aufweist; und
3. (c) das Material in dem Kern schädlingsbekämpfend wirkt.

It is an object of the invention to provide a knitted garment which has good thermoregulating properties and is largely insensitive to pests. According to the invention the object is achieved in that

1. (a) a yarn is used with a core made of a material that affects the properties of the garment,
2. (b) that the garment is made of yarn containing wool; and
3. (c) the material in the core acts as a pesticide.

It has been found that the thermoregulating properties are particularly good if the yarn contains wool. The pest control material is used in a core. This avoids direct contact with the skin. The pest control material cannot be easily washed out. An example of a pest control material contains permethrin. However, any other means are also conceivable, such as lavender.

In a further embodiment of the invention, the material contains a phase change material (PCM). Then the garment has particularly good thermoregulating properties.

Such a knitted garment can be used as a pesticide for other garments which are stored together with the knitted garment. Because the pesticidal effect of the pesticide is not limited to the garment, but radiates to all garments that are stored together with the knitted garment.

Embodiments of the invention are the subject of the dependent claims. An exemplary embodiment is explained in more detail below.

Description of the embodiment

In the present embodiment, the knitted garment is a sweater. The sweater is knitted from a yarn spun from a mixture of wool, cellulose and polyester. The cellulose has a fiber covering and a core. The core material contains permethrin. In this way pest feeding, especially by moths and their larvae, is avoided. In addition, mosquitoes cannot sting through clothing.

Claims (3)

Garment knitted from phase change material (PCM) - yarn in which a paraffin core is introduced directly into cavities of a cellulose fiber during the spinning process according to the Lyocell process, the yarn being made from a mixture of wool, cellulose and polyester or another mixture with a wool component and cellulose and the cellulose has a fiber covering and a core, so that direct contact of the material in the core with the skin is avoided, characterized in that the core influences the properties of the garment, contains permethrin or lavender and pest-controlling works. Garment after Claim 1 , characterized in that it is selected from the group consisting of jackets, sweaters, vests, dresses, skirts, pants, shirts or coats. Use of a knitted garment according to one of the preceding claims as a pesticide for further garments which are stored together with the knitted garment.
