METODE PEMBERIAN PELUMAS PADA PEMBUATAN BENANG-BENANG FILAMEN SERAT SINTETIK UNTUK PROSES PENGGINTIRAN PALSU YANG SALING KONTAK DENGAN PANAS

摘要

PROBLEM TO BE SOLVED: To thoroughly prevent a heater from staining and inhibit a yarn from fluffing and breaking by applying a specific lubricant to the synthetic filament yarn under specific conditions. ;SOLUTION: A water-based lubricant containing ≤50 pts.wt. of a linear polyorganosiloxane and 100 pts.wt. of a polyether is adjusted in its pH to 7-9 and the lubricant is applied to a synthetic filament yarn in an amount of 0.1-3wt.% and moisture is applied in an amount 0.2-10 times that of the lubricant. (A) A linear polyorganosiloxane constituted with the recurrent units having 4-12 siloxane units of formula I (R¹ and R² are independent from each other and represent each a 1-4C alkyl) and/or (B) a linear polyorganosiloxane constituted with the recurring units having the siloxane units of formula I and the siloxane units of formula II (R³ is a 1-4C fluoroalkyl; R⁴ is a 1-4C fluoroalkyl, a 1-4C alkyl) by 4-12 units where the siloxane units of formula II is ≤25mol% of the total siloxane units are mixed with a polyether.;COPYRIGHT: (C)1998,JPO
