Description

SUSTAINABLE COMPOSITION AND PROCESS FOR PRODUCTION OF STAIN REPELLENT TEXTILE ARTICLE
BACKGROUND
Technical Field
[0001] The embodiments herein generally relate to production of stain repellent textile articles, and, more particularly, to a composition and process for production of the stain repellent articles having both sustainability and durability.
Description of the Related Art
[0002] In general, the production of the textile articles (e.g. such as denims, fabrics, t- shirts, clothes, pants and other substrates) it is desirable to improve the properties of the textile articles like stain repellency to obtain stain repellent textile articles. The stain repellent textile articles are highly preferred by consumers as the stain repellent textile articles facilitate cleaning.
[0003] In general, an existing composition and process for the production of the stain repellent textile articles imparts or focuses either only on sustainability or durability. The quality of the stain repellent textile article depends on the percentage of both sustainability and durability imparted in the stain repellent textile article. Also achieving high degrees of repellency is generally desirable. The existing composition and process are also not comfortable enough to provide sufficient degree of repellency. The existing composition and process further resist breathability that may decrease the life span of the stain repellent textile articles.
[0004] Accordingly, there remains a need for an improved composition and process for production of stain repellent textile articles that are adapted for sustainability, durability and breathability.
SUMMARY
[0005] The main objective of the present invention is to provide a stain resistant composition for producing stain repellent article with both sustainability and durability.
[0006] In one embodiment, the present invention relates to a stain resistant composition comprising: a) about 3 % to 8 % of at least one silicon nano particle surface functionalized with fluoro polymer, wherein the fluoro polymer is (Pentafluorophenyl)triethoxysilane, and (b) about 3 % to 8 % of at least one hydrophobic agent selected from a group comprising polymer of (a) methacrylic esters of aliphatic CI to CI 8 alcohols, or (b) vinyl acetate, or (c) acrylonitrile.
[0007] In further embodiment, the stain resistant composition also comprises: (a) about 0.2 % to 0.5 % of at least one softening agent, wherein the at least one softening agent is selected from a group comprising of (a) organic modified polysiloxane or (b) quaternized hydroxyethylcellulose, (b) about 1 % to 1.5 % of an extending agent, wherein the extending agent includes an aqueous emulsion of blocked polyisocyanate, (c) about 0.1 % to 0.3 % of at least one of (i) a wetting agent or (ii) a re-wetting agent, wherein the wetting agent or re- wetting agent includes Isopropyl alcohol, and (d) 0.5 % to 1 % of a microencapsulated odour neutralizing agent, wherein the microencapsulated odor neutralizing agent includes metallic silver micro particles.
[0008] In another embodiment, the present invention relates to a process of preparing a stain repellent textile article with sustainability, breathability and durability, comprising: (a) padding a textile article at 1.5 to 2 bar pressure with a stain resistant composition in a room temperature, wherein the stain resistant composition comprises (i) 3 % of at least one silicon nano particle surface functionalized with (Pentafluorophenyl)triethoxysilane, and (ii) 6 % of at least one hydrophobic agent selected from a group consisting polymer of (a) methacrylic esters of aliphatic CI to CI 8 alcohols, or (b) vinyl acetate, or (c) acrylonitrile, (b) squeezing the textile article obtained from step (i) to remove excessive amount of the stain resistant composition from the textile article using squeeze rollers; (c) drying the stain resistant textile article obtained from step (ii) at a temperature ranges from 110 °C to 150 °C for 1 minute to fix the stain resistant composition on the textile article, and (d) curing the textile article obtained from step (iii) at 175 °C temperature for 5 to 6 minutes to obtain the stain resistant composition coated textile article.
[0009] In an embodiment, the textile article is a fabric article.
[0010] In yet another embodiment, the present invention relates to a process of preparing a stain repellent garment textile article with sustainability, breathability and durability, comprising: (a) dipping the garment textile article in a chemical bath for a predefined time period comprising (i) 3 % to 8 % of at least one silicon nano particle surface functionalized with (Pentafluorophenyl)triethoxysilane, and (ii) 3 % to 8 % of at least one hydrophobic agent selected from a group consisting polymer of (a) methacrylic esters of aliphatic CI to C18 alcohols, or (b) vinyl acetate, or (c) acrylonitrile (b) hydro extracting the excess chemical from the garment textile article obtained from step (i), (c) tumble drying the stain resistant garment textile article obtained from step (ii) at 100 °C for a second predefined time period, and (d) loading the stain resistant garment textile article obtained from step (iii) into a chlorine chamber for the predefined time period.
[0011] In further embodiment, the stain resistant composition used for producing textile article with sustainability, breathability and durability also comprises: (a) about 0.2 % to 0.5 % of at least one softening agent, wherein the at least one softening agent is selected from a group comprising of (a) organic modified polysiloxane or (b) quaternized hydroxyethylcellulose, (b) about 1 % to 1.5 % of an extending agent, wherein the extending agent includes an aqueous emulsion of blocked polyisocyanate, (c) about 0.1 % to 0.3 % of at least one of (i) a wetting agent or (ii) a re-wetting agent, wherein the wetting agent or re- wetting agent includes Isopropyl alcohol, and (d) 0.5 % to 1 % of a microencapsulated odour neutralizing agent, wherein the microencapsulated odor neutralizing agent includes metallic silver micro particles.

(ii) hydro extracting the excess chemical from the garment textile article obtained from step (i);
(iii) tumble drying the stain resistant garment textile (118) article obtained from step (ii) at 100 °C for a second predefined time period; and
(iv) loading the stain resistant garment textile article (106) obtained from step (iii) into a chlorine chamber for the first predefined time period.
8. The process as claimed in claim 7, wherein said strain resistant composition (102) comprises (i) 0.2 % to 0.5 % of at least one softening agent (110) selected from a group comprising of (a) organic modified polysiloxane, or (b) quaternized hydroxyethylcellulose, (ii) 1 % to 1.5 % of an extending agent (108), wherein said extending agent includes an aqueous emulsion of blocked polyisocyanate, (iii) 1 % to 0.3 % of at least one of (i) a wetting agent or (ii) a re-wetting agent (112) wherein said wetting agent or re-wetting agent includes Isopropyl alcohol, and (iv) 0.5 % to 1 % microencapsulated odour neutralizing agent (114), wherein said microencapsulated odor neutralizing agent includes metallic silver micro particles.
9. The process as claimed in claim 8, wherein said stain resistant composition (102) in a chemical bath having Material Liquor Ratio (MLR) of 1 : 1 to 1 : 1.5.
10. The process as claimed in claim 7, wherein the process is applied to a portion of the textile article, wherein the portion of the textile article is selected using a cross linking structure, wherein the predefined time period is 20 minutes and the second predefined time period is 40 minutes.
