Benefits of technology

The present invention relates to a fiber made of a polymer composition comprising at least one semi-aromatic polyamide, which has anti-staining properties. The invention also includes textiles and carpets made of this fiber that feature outstanding anti-staining properties. The fiber is made by condensing terephthalic acid and at least one aliphatic diamine. The invention provides a solution to the problem of staining in polyamide fibers, which are commonly stained when exposed to staining agents such as artificial or natural colorants and makeup. The invention offers a way to make polyamide fibers resistant to staining, increasing their life span and reducing the need for replacement due to staining.

Problems solved by technology

As a consequence, polyamide fibers, textiles and carpets suffer from a significant drawback: they are not resistant to staining agents that are often put in contact with these articles.
In contact with these staining agents, the prior art articles are easily stained.
The resulting stains cannot be easily removed under ordinary cleaning conditions.
The severe staining of carpeting is a major problem for consumers.
In fact, surveys show that more carpets are replaced because of staining than because of wear.
Topical treatments, however, tend to be costly and non-permanent (washed away with one or more washings).

Abstract

The present invention relates to stain- or dye-resistant light colored fibers, textiles and carpets made of a polymer composition (C) comprising at least one semi-aromatic polyamide comprising recurring units resulting from the condensation of terephthalic acid and at least one aliphatic diamine selected from the group consisting of 1,8-octanediamine, 1,9-nonanediamine, 2-methyl-1,8-octanediamine, 1,10-decanediamine, 1,12-dodecanediamine, 2,2,4-trimethyl-1,6-hexanediamine, 2,4,4-trimethyl-1,6-hexanediamine, 5-methyl-1,9-nonanediamine, methylcyclohexanediamine, isophoronediamine and mixtures thereof.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a U.S. national stage entry under 35 U.S.C. §371 of International Application No. PCT / EP2011 / 067902 filed Oct. 13, 2011, which claims priority to U.S. application No. 61 / 392864 filed on Oct. 13, 2010 and European application No. 11157969.4 filed on Mar. 11, 2011, the whole content of these applications being incorporated herein by reference for all purposes.FIELD OF THE INVENTION[0002]The present invention broadly relates to low color fibers, textiles and carpets comprising a semi-aromatic polyamide that feature surprisingly anti-staining properties. The invention relates also in particular to the use of a semi-aromatic polyamide in the manufacture of fibers, textiles and carpets for its anti-staining properties.BACKGROUND OF THE INVENTION[0003]Polyamides (like those derived from phthalic acids and aliphatic diamines, i.e. polyphthalamides, or those derived from aromatic diamines and aliphatic diacids) are polymers hav...
