Abstract
The invention pertains to a woven antistatic flexible intermediate bulk container (FIBC) comprising a polyolefin fiber or strip containing as an antistatic additive a polyetheresteramide, a polyester-ether block copolymer or an antistatic composition containing said polyetheresteramide or said polyester-ether block copolymer at least partially, as warp and/or weft thread.
Claims12
A woven antistatic fabric, useful in a woven flexible intermediate bulk container (FIBC), said fabric comprising a polyolefin fiber or strip containing as an antistatic additive a polyetheresteramide, a polyester-ether block copolymer or an antistatic composition containing said polyetheresteramide or said polyester-ether block copolymer at least partially, as warp and/or weft thread.
A process for manufacturing a woven antistatic fabric, useful in a flexible intermediate bulk container, the process comprising
- incorporating into a polyolefin fiber or strip as antistatic additive a polyetheresteramide, a polyester-ether block copolymer or an antistatic composition containing a polyetherester-amide or a polyester-ether block copolymer and
- weaving said polyolefin fiber or strip at least in part as warp and/or weft thread into the fabric.
A woven antistatic fabric, useful in a woven flexible intermediate bulk container (FIBC) said fabric comprising a polyolefin fiber or strip which fabric has a coating on the inner and/or outer surface containing as an antistatic additive a polyetheresteramide, a polyester-ether block copolymer or an antistatic composition containing a polyetheresteramide or a polyester-ether block copolymer in an amount of 7%-30% based on the solid weight of the coating.
