A fluid-permeable agent for providing fluid-permeability to non-woven sheets of polyolefin fibers contains 50 wt % or more of polyoxyalkylene modified silicone shown by Formula (A) given below: ##STR1## where x is an integer in the range of 1-10, y is an integer in the range of 7-100, a is an integer equal to or greater than 5, b is an integer equal to or less than 95, (a+b) is an integer equal to or less than 100 and R.sup.1 is H or alkyl group with 1-12 carbon atoms. The agent may additionally contain surfactants of certain specified kinds and is applied at a rate of 0.1-0.5 wt % with respect to the fibers for good results.

Fluid-permeable agent for non-woven sheets of polyolefin fibers and

A fluid-permeable agent for providing fluid-permeability to non-woven sheets of polyolefin fibers contains 50 wt % or more of aliphatic diethanol amide shown by the formula: ##STR1## where R is alkyl or alkenyl group with 11-17 carbon atoms. The agent may additionally contain non-ionic surfactants and salt of certain specified kinds and is applied at a rate of 0.1-0.5 wt % with respect to the fibers for good results.

Fluid-permeable agent for non-woven sheets of polyolefin fibers

For cotton spinning, use is made of a treatment agent containing silicone with viscosity at 25.degree. C. of 10 centistokes or greater such as dimethylsilicone, end hydroxy modified dimethylsilicone or epoxy modified dimethylsilicone and an emulsifier such as polyoxyethylene alkylether or polyoxyethylene alkylphenylether. The treatment agent may also contain a cationic or non-ionic surface-active agent within a specified range of weight ratio. The treatment agent is applied to raw cotton during its bale opening or beating opener process at the rate of 0.001-2.0 wt %.

Lubricants for cotton spinning

A fluid-permeable agent for providing fluid-permeability to non-woven sheets of polyolefin fibers contains 50-95 wt % of aliphatic diethanol amide shown by Formula (A) given below and 5-50 wt % of polyoxyalkylene modified silicone shown by Formula (B) given below: ##STR1## where R.sup.1 is alkyl or alkenyl group with 11-17 carbon atoms; and ##STR2## where x is an integer in the range of 1-10, y is an integer in the range of 7-100, a is an integer equal to or greater than 5, b is an integer equal to or less than 95, (a+b) is an integer equal to or less than 100 and R.sub.2 is H or alkyl group with 1-12 carbon atoms. The agent may additionally contain nonionic surfactants and salt of certain specified kinds and is applied at a rate of 0.1-5.0 wt % with respect to the fibers for good results.
