Abstract

The invention relates to an anti-crease and anti-shrink finishing process for a wool fabric, which comprises an anti-crease and anti-shrink finishing step, a water washing step and a natural drying step and is characterized in that the anti-crease and anti-shrink finishing step comprises the procedures of firstly pretreating the wool fabric through plasma, and then treating the wool fabric pretreated by the plasma by adopting transglutaminase, wherein in transglutaminase treatment, the transglutaminase concentration is 13-25%(o.w.f), the treatment temperature is 30-45 DEG C, the treatment time is 30-50 minutes, and the treatment bath ratio is (1:15)-(1:20); and then carrying out anti-crease finishing on the wool fabric by using a specific durable anti-crease and anti-shrink finishing agent and adopting a two-soaking and two-rolling finishing process. According to the invention, the specific durable anti-crease finishing agent is added for treating the wool fabric in the anti-crease finishing process, so that the crease resistance is increased, the felting shrinkage is less than 2%, and the burst is reduced to be lower than 10%. Moreover, the finishing process is safe and environment-friendly and is an energy-saving clean wool after-finishing process.

Description

Technical field [0001] The invention relates to the field of anti-wrinkle and anti-felting of wool, in particular to a process for anti-wrinkle and anti-shrinkage finishing of wool fabrics. Background technique [0002] When woolen products are processed and washed, the friction of the oriented scales will cause displacement between the fibers, resulting in milling, resulting in size shrinkage, unclear lines, etc., which will seriously affect the appearance, feel, easy care and wearing performance. At present, the domestic wool anti-felting process generally uses the more mature chlorination method and the two-step chlorination-resin method (IWS / CSIROChlorineHercosett method). These two methods are based on chlorination treatment, which are easy to absorb chlorine and yellow, and damage the fiber strongly. Not only does the wool fiber suffer from severe chemical erosion, but also there is a large amount of absorbable organic halogenated AOX ( Absorbableolganichalagen) will remai...
