Clothing comprising a fabric, comprising elastic fibers

Abstract

Sports clothing, protective clothing, clothing for body shaping and clothing with a medical function, which clothing comprises at least one fabric comprising elastic fibers, which elastic fibers are produced from a polymer composition comprising a copolymer containing 20-80 wt. % of monomeric units of a dimerized fatty acid or a derivative thereof and further monomer units of at least one dicarboxylic acid and at least one diol.

Claims

1. Clothing comprised of at least one fabric comprising elastic fibers, wherein the elastic fibers are formed of a polymer composition comprising a copolymer containing 20-80 wt. % of monomeric units of a dimerised fatty acid or a derivative thereof and further monomer units of at least one dicarboxylic acid and at least one diol, wherein the clothing is selected from the group consisting of sports clothing, protective clothing, clothing for body shaping and clothing with a medical function.

2. The clothing according to claim 1, wherein the copolymer contains between 20 and 70 wt. % of the monomer units of the dimerised fatty acid and/or a derivative thereof.

3. The clothing according to claim 1, wherein the copolymer contains between 30 and 50 wt. % of the monomer units of the dimerised fatty acid and/or a derivative thereof.

4. The clothing according to claim 1, wherein the at least one dicarboxylic acid is terephthalic acid.

5. The clothing according to claim 1, wherein at least one diol is 1,4-butanediol.

6. The clothing according to claim 1, wherein the copolymer consists of at least 98 wt. % of monomeric units of dimerised fatty acid and/or one or more derivatives thereof, 1,4-butanediol and terephthalic acid.

Description

COMPARATIVE EXPERIMENTS A AND B, EXAMPLE I.

(1) Elastic fabrics having a size of 100100 mm were tested on water uptake according to DIN 53923, version 1978-01.

(2) The tests were performed at 20 C. and 65% relative humidity. The samples were immersed in water of 20 C. for a period of 60 seconds and allowed to drip off for 120 seconds after that. The weight of the fabric before (W.sub.bef) and after immersion (W.sub.af) was measured. The water uptake was calculated by:
[(W.sub.afW.sub.bef)/W.sub.bef]*100%.

(3) Of each fabric 5 samples were tested and the average value is given. The fabric of comparative experiment A consists of PET/Elastan yarns, the fabric of comparative experiment B consists of PA/Elastan yarns. The fabric of example I consists of yarns of Arnitel Eco, a polymer comprising monomeric units of a dimerised fatty, 1,4-butanediol and terephthalic acid. The results are presented in Table 1.

(4) TABLE-US-00001 TABLE I Average water uptake (%) Comparative experiment A. 277.9 Comparative experiment B. 437.8 Example I. 155.8
The fabric according to the invention clearly shows a much lower water uptake than the fabrics according to the state of the art.
