Abstract
The present invention relates to the use of compounds for imparting a temperature regulating effect to a textile and methods of manufacturing a temperature regulating textile. The present invention also relates to a method of manufacturing a temperature regulating textile, wherein the textile forms part of a non-apparel article. Compounds for imparting a temperature regulating effect on a textile are also described.
Claims28
Use of a compound according to formula (I) for imparting a temperature regulating effect to a textile:
- A-(B)r (I);
- wherein:
- A is a polymer;
- B is selected from the group consisting of —NHR1, —OH, —SH, —NR1-L1-X, —O-L1-X and —S-L1-X wherein:
- R1 is H or optionally substituted —C1-6alkyl;
- L1 is a linker with a chain length having an integer from 1 to 10 atoms;
- X comprises an electrophilic moiety capable of accepting electrons from a nucleophile to form a covalent bond;
- r is an integer from 1 to 3 and
- wherein the melting point of the compound is from about 5° C. to about 55° C. and the use comprises forming a covalent bond between B and the textile.
The use according to any one of the preceding claims, wherein the compound according to formula (I) is
- wherein x, y and z are as defined according to any previous claim, provided that x+z is from 5 to 10 and y is from 35 to 45, preferably wherein x+z is 6 and y is 39.
The use according to any one of the preceding claims, wherein the melting point of the compound is from about 20° C. to about 45° C., from about 15° C. to about 35° C., or from about 20° C. to about 35° C.
The use according to any one of the preceding claims wherein the enthalpy of fusion is from about 10 J/g to about 200 J/g, or from about 40 J/g to about 150 J/g.
A method of manufacturing a temperature regulating textile comprising:
- applying a compound of formula (I) to a textile and forming a covalent bond between the compound and the textile to provide the temperature regulating textile;
- A-(B)r (I);
- wherein:
- A is a polymer;
- B is selected from the group consisting of —NHR1, —OH, —SH, —NR1-L1-X, —O-L1-X and —S-L1-X wherein:
- R1 is H or optionally substituted —C1-6alkyl;
- L1 is a linker with a chain length having an integer from 1 to 10 atoms;
- X comprises an electrophilic moiety capable of accepting electrons from a nucleophile to form a covalent bond;
- r is an integer from 1 to 3 and
- wherein the melting point of the compound is from about 5° C. to about 55° C.;
- and wherein, when B is selected from the group consisting of —NR1-L1-X, —O-L1-X and —S-L1-X, the forming a covalent bond between the compound and the textile comprises forming a covalent bond between the electrophilic moiety capable of accepting electrons from a nucleophile and a nucleophilic group on the textile;
- and, when B is selected from the group consisting of —NHR1, —OH and —SH, the forming a covalent bond between the compound and the textile comprises forming a covalent bond between B and an electrophilic moiety on the textile;
- provided that the compound of the formula (I) is not a compound according to any of formulae (VI) to (IX) defined below:
- wherein x, y and z are each a positive integer or zero and x+y+z is from about 35 to about 65, preferably from about 45 to about 55;
- wherein x, y, and z are positive integers and independently selected from about 5 to about 20;
- and n is 4;
- wherein x, y, and z are positive integers and independently selected from about 5 to about 20;
- n is 4;
- and q is 0 to 2, optionally 1 to 2;
- and
- wherein x is a positive integer from about 10 to about 50, preferably from about 25 to about 35;
- wherein L3, L4 L5, L6, L7, L8, L9, L10, L11, and L12 are each independently selected from H;
- and (*) denotes the point of attachment to —NH.
A compound selected from the following:
- wherein x, y and z are each integers, and wherein x+z is from 5 to 10 and y is from 35 to 45, preferably wherein x+z is 6 and y is 39.
A compound selected from the following:
- wherein x and y are integers, the ratio of x to y is about 11:1 and wherein the average molecular weight is from about 1700 to 2500, e.g. about 2000.
