Abstract

The invention discloses a PTT blended union fabric and the dyeing processing method. dry-hot shrinkage of fabric is in +-1. 5% and washing shrinkage is in +-1. 5%. The dyeing processing method comprises pre-setting treatment of grey cloth, refining and drying, hot-setting treatment in high temperature again, alkali decrement handling, dyeing, resin finishing, hot-setting treatment in high temperature at the third time and so on. The invention is provided with puff and soft handling, good elasticity and stable dimension. The elasticity is more than 15% and the recovery of elasticity is more than 90%. It is also provided with good tailoring and ironing performance.

Description

Technical field: [0001] The invention relates to a post-treatment method of poly(trimethylene terephthalate) blended and interwoven fabrics. Background technique: [0002] Polytrimethylene terephthalate (PTT) is a new type of modified polyester resin. Fabrics made of PTT fibers are widely used in the knitting industry. The weaving process in the weaving industry has become increasingly mature, but the dyeing and finishing process is still Not perfect. Because the fabric made of PTT fiber has good elastic recovery and softness, it is widely favored by people. However, the fabrics processed by ordinary dyeing and finishing methods have poor dimensional stability, dry heat shrinkage of ±4% to ±5%, washing shrinkage of ±3% to ±4%, and sewing and ironing. Wrinkles and other shortcomings limit the wide application of PTT fiber in the textile industry. The yarn of polytrimethylene terephthalate PTT blended interwoven fabric contains polytrimethylene terephthalate and polyethylen...
