Embodiment

[0164] combination

[0165] The various compounds used to prepare the silicone compositions are detailed in Table 1 below.

[0166] Note: For all examples, PDMS oil = polydimethylsiloxane oil.

[0167] Table 1

[0168]

[0169] The various two-component compositions tested (Parts A and B) are detailed in Table 2 below. For each test, 100 parts by weight of Part A were mixed with 10 parts by weight of Part B.

[0170] Table 2

[0171]

[0172]

[0173]

[0174] All silicone compositions tested were non-toxic and did not emit odour.

[0175] For each composition tested, two types of tests were performed.

[0176] 1. method according to the invention : After mixing Parts A and B, the composition is applied continuously at a thickness of 0.3 mm on standard knitted lace based on polyamide, polyester and élasthanne. The coated lace was then passed for 5 minutes in an oven at a temperature of 90° C. to crosslink the silicone composition. No migration of the silic...

Embodiment 4

[0197] Embodiment 4 (SiH 交联 / SiVi = 0.38, but no monovinyl carburetion was present).

[0198] The feeling of stickiness can be correlated with the results obtained in the friction test used to evaluate the adhesion, and the feeling of pressure can be correlated with the modulus of elasticity of the elastomer used. This is because, when the required peeling force is less than 35N (comparative tests 1 and 4), the user has no sticky feeling, but the elastic modulus of the coated elastomer is high and the user feels an annoying pressure feeling . On the other hand, when the measured required peel force was greater than 55 N (comparative tests 2 and 3), the user experienced an unpleasant feeling of stickiness, which was not acceptable for the application.

[0199] Comparative Examples 2 and 3 show that when the silicone composition does not contain monovinylated polyorganosiloxane and the SiH / SiVi molar ratio is less than 1, the level of adhesion or tack is too high (94 and 101N)...

Abstract

The present invention relates to a method of coating a textile with a silicon elastomer composition that can be crosslinked by polyaddition, enabling the textile to be given a non-slip property. The invention also relates to textile articles thus coated, such as clothing and lace, exhibiting good adhesion to various mediums, such as skin, another textile, a fibrous medium, etc.

Description

technical field [0001] The present invention relates to a method for coating a textile support with an elastomeric silicone composition crosslinkable by polyaddition, making it possible to impart non-slip properties to the textile. The invention also relates to textile articles, such as garments and dentelles, so coated, which have good adhesion to various supports such as skin, additional fabrics, fibrous supports and the like. [0002] The general field of the invention lies in the use of silicone compositions crosslinkable by polyaddition reactions for producing thin-layer elastomers as coatings for various textiles. Background technique [0003] Such silicone coatings can be obtained by coating a fibrous support followed by polyaddition of unsaturated groups (alkenyl groups, e.g. Si-Vi) of a polyorganosiloxane to the same or another polyorganosiloxane Hardened by the hydrogen of the alkane. [0004] It is known to use silicone compositions for coating textile materials...
