Embodiment 1

[0022] A kind of technology of linen fabric post-finishing, the finishing liquid used is the finishing liquid of chitosan degraded by citric acylation.

[0023] (1) Carry out finishing solution padding to the linen fabric of scouring and bleaching, use citricylated degraded chitosan finishing solution, its composition and weight ratio are: citricylated degraded chitosan consumption 4%, catalyst The dosage of sodium hypophosphite is 4%; the finishing bath uses water as a solvent, and the above-mentioned finishing solution is added, and the ratio of finishing solution to water is 1:20, and a softener and a penetrating agent are also added in the finishing bath. Softening agent and penetration agent here are prior art.

[0024] (2) Pre-baking the fabric, the pre-baking temperature is 80°C, and the pre-baking time is 150 seconds; (3) The fabric is baked at a high temperature, the baking temperature is 160°C, and the baking time is 180 seconds.

Embodiment 2

[0026] A kind of technology of linen fabric post-finishing, the finishing liquid used is the finishing liquid of chitosan degraded by citric acylation.

[0027] (1) Use the citricylated degraded chitosan finishing solution, its composition and weight ratio are: citricylated degraded chitosan consumption 5%, catalyst sodium hypophosphite 3%; the rest is the same as Example 1.

[0028] (2) Pre-baking the fabric, the pre-baking temperature is 85°C, and the pre-baking time is 120 seconds; (3) Carrying out high-temperature baking to the fabric, the baking temperature is 180°C, and the baking time is 150 seconds.

Embodiment 3

[0030] A finishing process for linen fabrics, the finishing solution used is a compound finishing solution of citric acid degraded chitosan and citric acid.

[0031] (1) Carry out finishing liquid padding treatment to the flax fabric that has been scoured and bleached, and the finishing liquid is a compound finishing liquid of citric acid degraded chitosan and citric acid, and its composition and weight ratio are: finishing agent citric acid The dosage of degrading chitosan is 3%, the dosage of citric acid is 1%, and the dosage of catalyst sodium hypophosphite is 4%.

[0032] (2) Pre-baking the fabric, the pre-baking temperature is 75°C, and the pre-baking time is 120 seconds; (3) Carrying out high-temperature baking to the fabric, the baking temperature is 155°C, and the baking time is 120 seconds.

Abstract

The invention discloses an after-finishing process of linen fabric. The used finishing liquid includes lemon acylation degradation chitosan finishing liquid and compound finishing liquid of lemon acylation degradation chitosan and citric acid. The after-finishing process of the linen fabric has the advantages that the invention provides an after-finishing process of the linen fabric without toxicity or formaldehyde release, the process well maintains the green environmental protection characteristics of the linen fabric, the used lemon acylation degradation chitosan finishing liquid can obviously improve the resistance of the linen fabric to deformation, also can improve the defects of easy crease and poor wearability of the linen fabric in the wearing process; besides, the finished fabric has higher whiteness and can ensure various mechanical properties to meet the requirements. The process also can maintain stable color of the fabric and has lasting finishing effect and higher washing fastness of the finished fabric.

Description

technical field [0001] The invention relates to a finishing process of linen fabric. Background technique [0002] Linen fabric has natural hand feeling, comfortable and rough wearing, high strength, good moisture absorption and desorption, etc., so it is known as the queen of natural fibers. However, flax fiber has many deficiencies such as low cellulose content, high pectin content, higher degree of fiber polymerization, crystallinity, and orientation than cotton fiber. The previous flax fiber has low elasticity and poor wrinkle recovery. It is easy to wrinkle in the washing process, and the need for ironing after washing also brings a lot of inconvenience to consumers, so that the excellent characteristics of linen fabrics cannot be fully reflected. In order to solve this difficult problem, in the 1960s and 1970s, people designed the finishing process of linen fabric, which is mainly divided into physical (mechanical) finishing and chemical finishing. The most obvious e...
