Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a velor-like carpet. 1) More specifically, a velor-like carpet with antifouling properties, 1 antistatic property, etc., suitable for indoor use, vehicle use, etc. It is related to.

Recently, raised carpet has been attracting attention as an interior material for homes and automobiles. In particular, the non-piled needle-punch carpets that have been widely used in the past are monotonous, have a poor feel, and are inferior in appearance, etc., so the nap-like needle punch carpets, which have a luxurious feel, are attracting attention. However, raised carpets are often soiled by spilling drinks such as coffee and cola, which are not essential in daily life, or by crushing 1 salad oil and 1 butter. It is also known that in order to prevent such stains, carpets are treated to be water and oil repellent. In general, carpets that have been treated to be water- and oil-repellent can easily seep into the interior even if you bury beverages in them, so 1. Immediately wipe the carpet with tissue paper to remove dirt and stains. It has a noodle effect. However, 1.Especially if oil-based stains are left untreated without being wiped off immediately, and they dry and harden on the fibers, the stains become worse! It has the disadvantage that it cannot be removed with shampoo. In particular, when water and oil repellency is imparted through post-processing after carpet manufacturing, the water and oil repellent finishing agent mainly adheres only to the tips of the raised wA fibers, so the 1-strand hair fibers have a poor stain-proofing effect, and the inside of the 1. The problem is that the dirt that has entered is difficult to remove.

The inventors of the present invention have arrived at the present invention as a result of intensive research in order to obtain a raised carpet with excellent stain resistance.

In other words, 1 the present invention comprises napped fibers made of synthetic I1m having water and oil repellency and having a denier smaller than that of the napped fibers.
The stain-resistant velor-like carpet is characterized in that it is made of fluted fibers made of hydrophilic synthetic fibers.

The carpet of the present invention will be explained with reference to the drawings. 1 Fig. 1 is a schematic cross-sectional view showing an example of the antifouling carpet of the present invention;
3i! Base fabric 54Fi backing layer.

In the carpet according to the present invention, since the napped fibers are water and oil repellent, liquid stains can be easily removed by wiping. Since the fibers are hydrophilic, this stain can be easily removed by wiping it with a damp towel or the like. In addition, even if oily stains become internal K11, they can be easily removed with shampoo, so they do not become stains.

Furthermore, there is carbon tin in the banking latex.

When blending conductive fibers and/or conductive substances such as gold HII411am-% carbon black, an excellent antistatic effect can be achieved in combination with the antistatic properties of the hydrophilic hem fibers. It is also possible to correct the dullness phenomenon caused by adsorption of 1#t stiffness.

Each fiber constituting the carpet of the present invention will be explained below.

As the napped fibers, synthetic llAm having water and oil repellency is used, but the fineness of the fibers is preferably 10 deniers or more.

Examples of synthetic fibers include polyester, holamide, polyacrylonitrile, etc., and polyester is particularly preferred. Polyesters include polyethylene terephthalate, polybutylene terephthalate, polyethylene terephthalate, polyethylene terephthalate, polyethylene butylene terephthalate, 15-sodium sulfoisophthalate copolymer, ethylene terephthalate, F-based polyester, and various fiber-modified polyesters. . Water and oil repellency can be imparted by applying a finishing agent to the surface of the carpet after it has been made into a carpet, but it is usually done by applying a finishing agent to the surface of the carpet. It is preferable to treat the yarn. In particular, from the viewpoint of effectiveness and economy, it is preferable to apply the treatment to the undrawn yarn or semi-drawn yarn after spinning in combination with an oil agent in the same bath or in a separate bath.

The treatment agent that imparts water and oil repellency is a fluorine-containing compound having a perfluoroalkyl group, such as an ethylenically unsaturated monomer having a perfluoroalkyl group alone or together with other ethylenically unsaturated monomers. Copolymers with unsaturated monomers, addition polymers of oligomers consisting of ethylenically unsaturated monomers having perfluoroalkyl groups and 1-lyglycol having an SH group at the end, perfluorosiloxanes 1-perfluoroalkyl Compounds having a chemical group and a cyclotetratriazine group, a methylol group, an isocyanate group, etc. A processing agent obtained by reacting a perfluorocarboxylic acid and a perfluoroalcohol with a polyester oligomer is exemplified. be done.

On the other hand) synthetic fibers having #i hydrophilicity are used as the nap fibers, but fibers with a denier smaller than 1 nap fiber are used. Examples of synthetic fibers include napped fibers, esters, polyamides, polyacrylonitrile, etc., with polyesters being particularly preferred. To impart hydrophilicity, synthetic fibers obtained by modifying l-rimer to make it hydrophilic can also be used in the polymerization stage, but especially undrawn yarn after spinning.
It is preferable to carry out post-treatment with yarns such as semi-drawn yarns, drawn yarns and dyed yarns. The processing agent used is t-! block copolymer with f polyester polyethylene glyfur,
In addition to polyethylene glycidyl ether, polyethylene glycol 1 has an ethylenically unsaturated group.
Examples include polymers of hydrophilic monomers such as ethylenically unsaturated carboxylic acids, and copolymers mainly composed of the hydrophilic monomers with other ethylenically unsaturated monomers. It is also preferable that the fiber be modified by graft polymerizing a hydrophilic monomer. Particularly preferred is a fiber modified by applying a block copolymer of polyalkylene terephthalate and polyethylene glycol to undrawn yarn 1 and then stretching the undrawn yarn.

For example, carpet production involves mixing napped fibers with napped fibers, carding the resulting web into the shape of a base fabric (or, if desired, using the base fabric and needle-punching it, followed by patterning). Method 5II4 of using a punching machine to form a fluff pattern into a fluffy pattern to form raised fluff and fluff.
After tufting the shrinkable knitted fiber blend yarn, pile cut it 1
Next, a method of forming a raised pile and a fluted pile using the difference in shrinkage, and a method of forming a pile cloth by mixing different shrinkage fibers and then forming a raised pile and a fluffed pile in the same manner are exemplified. A light stabilizer, a flame enhancer, an antistatic agent, an antibacterial agent, etc. may be used in combination to modify the raised hair.

The present invention will be explained below with reference to Examples.

Example L Immediately after spinning polyethylene terephthalate from a circular nozzle, 0.15% owf (solid content) of Asahi Gardom G-800 (Meisei Kagaku Kogyo Co., Ltd.: fluorocarbon water and oil repellent) was added to the alkyl phosphate system.

A single fiber of 14m111 was obtained as a delicate material for use on the hem. After dyeing each fiber, the M fiber for the standing hand was mixed with the L114m fiber for the hem hand and carded, and the obtained web was needle punched using the base fabric J. The 15-denier fibers were made into a fluffy shape using a machine, and the 15-denier fibers were made to be fluffy and the 16-denier fibers were fluffed. after that·
The back side was coated with Latte Hetsukuten to obtain a velor-like needle punch carpet. The nape-like needle punch carpet seen in this way is also ic:t-
Even when liquids such as coffee and cola were dropped, they formed into spherical droplets on the surface and could be wiped off immediately with tissue paper. t1 Colored salad oil and rubbed it and left it for 11 weeks? II! After pouring some hot water on it and wiping it with a rag, it came out clean.

Example 2 6-sodium sulfoisophthalic acid in grams per total acid component
The same effect as in Example 1 was obtained using ethylene tele-7 tallade polyester copolymerized with a mol % (although two types of fibers were created and a raised needle punch carpet was created). there were.

Comparative Example Example 1 A fiber was made with water and oil repellency for both nape and nape.
In the same way as above, the carpet was made into a needle-punch carpet with a nape-like appearance. (Kononoke Coffee) When I burnt cola, etc. - If I wiped it off immediately, the stain didn't stick, but I colored it with Rada oil and rubbed it on, left it for a week, then poured hot water over it and tried to wipe it off, but I couldn't completely remove it. There wasn't.

EXAMPLE In Example 2, a heat-generating carpet was prepared by attaching an adhesive side to the back side of the raised carpet and pasting it with heat-generating seeds. When this was used in a kitchen, etc., even if muddy water was spilled, the sewage passed through to the heat generating sheet layer (it was easily removed and did not cause darkening of the paper).
