| titleOfInvention | The Processes and apparatus of staple fibre continuous yarn non-woven fabrics is prepared based on dry spinning technology |
| abstract | The invention discloses a kind of techniques preparing staple fibre continuous yarn non-woven fabrics based on dry spinning technology, include the following steps：The preparation of spinning technique (1), spinning solution；(2), liquid Hirschfeld-Klinger reaction and N-methyl morpholine oxide (NMMO) is recycled, the molding of (3), staple fibre；(4), it washes；(5), drawing-off：Non-woven fabrics moulding process；(6), lapping：It is as-spun fibre tow after drying and processing is evenly dispersed and be laid on lapper lace curtaining, form the filament web of stacking intersected with each other；(7), spun lacing is reinforced；(8), it dries；(9), it winds.Equipment is made of dry spinning device and non-woven fabric forming apparatus.Correlation step is omitted in the conventional dry spinning technique the step of, the staple fibre long filament of semi-finished product is directly used to carry out the production of non-woven fabrics, the technique has been broken traditional using the secondary concept for carrying out nonwoven production of finished fiber long filament, and it is effectively saved production cost, the pollution to environment in technical process is reduced, production efficiency is improved. |
