This is a very open-ended question. It is possible to coat fabrics, including pre-woven fibers. A rubberized coating might be an option for non-slip. Do you have any more details?

Agree with JimMetalsCeramics; you can't get a definite answer to a vague question.

Perhaps the following Dow Corning site concerns your topic:

"Fabric Coatings add toughness and heat resistance. They can also:
reduce slip on stocking tops, waistbands, socks, brassieres
reduce surface drag
improve soil release, crease and mar resistance
provide a 'paper' touch"

Thanks for the comments - sorry if the post was too vague. The clothing is a textile glove ( material to be confirmed) which is used in handling glass. The non-slip requirement is to improve safety. Rubberised coatings are being considered.
I am specifically interested in whether the textile raw material sould be coated prior to weaving , I hesitate with this as it could be extremely expensive bearing in mind our volumes are not huge at this time. Alternatively having the coating applied to the glove itself in the optimum areas to provide its non-slip properties would seem to me to be the best option. Additional comments welcome.

I thinkt you're better off with a final coating.  The initial cost will improve the durability to some degree, but if that cost is too high, you would have been better off with a cheaper, less durable glove, but with higher sales.
