Abstract

Textile fibers and textiles produced from Brassica plants retain properties that are favorable for textile manufacture. Also described are textiles manufactured from the textile fibers produced from the Brassica plants which exhibit properties that are favorable for apparel and domestic applications, as well as industrial applications. Methods for producing the textile fibers from Brassica plants are further described.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A method for producing textile fibres from Brassica plant stems, the method comprising the steps of:
conditioning the Brassica plant stems at a temperature of about 21° C. and a relative humidity of about 65%;
retting the conditioned Brassica plant stems by submersion in one of water or an alkali solution or an acid solution or an enzyme solution at a temperature selected from the range of about 20° C. to about 40° C. for a period of time selected from the range of 1 day to 5 days to produce bast fibres therefrom;
separating the Brassica bast fibres from the retted Brassica plant stems;
washing the separated Brassica bast fibres; and
drying the separated Brassica bast fibres,
wherein said dried separated Brassica bast fibers have a length variation that is less than ±3 mm.

2. The method according to claim 1 , wherein said enzyme solution is a 0.1% pectinase enzyme retting solution.

3. The method according to claim 1 , wherein the alkali solution is a 0.1% acid retting solution.

4. The method according to claim 1 , wherein the acid solution is a 0.1% alkali retting solution.

5. The method according to claim 1 , wherein the separated dried Brassica fibres are treated with any one of or a combination of treatments selected from the group consisting of enzyme treating, scouring, bleaching, dyeing, and softening.

6. The method according to claim 5 , wherein said scouring treatment is an alkali scouring, an acid scouring, or both alkali scouring and acid scouring.

7. The method according to claim 5 , wherein said dyeing treatment is with a reactive dye.

8. The method according to claim 5 , additionally comprising a step of combining the separated dried Brassica fibres with one or more secondary material fibres.

9. The method according to claim 8 , wherein the secondary material fibre is a natural fibre or a synthetic fibre or a combination thereof.
