Embodiment Construction
[0012] The present invention is further illustrated by the following examples, but not limited to the following examples.
[0013] Step 1. Cellulase pretreatment: select cellulase with a concentration of 1.5%-3% (o.w.f) to treat the silk hemp fabric (the silk hemp fabric used is 2.616tex silk and 25.196tex hemp yarn) The plain weave interweave fabrics woven by warp and weft yarns are pretreated respectively, the liquor ratio is 1:20, the pH value is adjusted to 4 with a 0.1mol / L hydrochloric acid solution made in the laboratory, and the treatment is carried out at 40°C for 60 minutes;
[0014] Step 2, softening and finishing: the silk hemp fabric is impregnated and softened with a softener formulated from ester-based quaternary ammonium salt, SF low-foaming penetrating agent, and OP-10 emulsifier. 90%, bath ratio 1:20, immerse at 60°C for 20min each time. Among them, the concentration of ester quaternary ammonium salt is 1g / L, the concentration of SF low foam penetrant is 0.5...

Abstract
The invention relates to a softening finishing method of silk-hemp fabric; cellulase with a concentration of 1.5% (o. w. f) is used to pretreat silk-hemp fabric, a softener made from the natural softener esterquats, SF low-foam penetrant and OP-10 emulsifier is used to perform double-soaking double-rolling softening finishing on the silk-hemp fabric; by using the method, softness of the silk-hemp fabric is effectively improved, the fabric is less itchy, and it is guaranteed that physical and mechanical properties of the silk-hemp fabric do not experience major influence.
Description
technical field [0001] The invention belongs to the technical field of post-treatment of fabrics, and in particular relates to a method for softening and finishing silk hemp fabrics. Background technique [0002] Silk is a kind of natural protein fiber, acid-resistant and alkali-resistant, light and slender, the fabric has good luster, comfortable to wear, smooth and plump, moisture-absorbing and breathable, used for weaving various satins and knitwear, silk has been used since ancient times The reputation of "Fiber Queen". [0003] Hemp fiber has the advantages of high temperature resistance, friction resistance, fast moisture absorption and heat dissipation, anti-allergic, anti-static and antibacterial, etc. It is a natural, harmless, renewable and cheap green fiber. However, hemp fiber contains more hemicellulose, lignin and pectin, coupled with higher crystallinity and orientation, which makes the fiber rigid, brittle, rough and hard to the touch, and itchy when in cont...
