Woolen yarn modification treatment process for preventing woolen yarns from being excessively hard

Abstract

The present invention discloses a woolen yarn modification treatment process for preventing woolen yarns from being excessively hard. The process comprises the following process steps of 1) soaking the woolen yarns in hot steam; 2) performing roll brushing of an alkali liquor on the woolen yarns; 3) spraying urea to adhere the woolen yarns; 4) soaking the woolen yarns with a softener solution; 5)performing roll brushing of a detergent on the woolen yarns; 6) spraying acetic acid water to the woolen yarns; and 7) performing blow drying by dry hot air. According to the specific operation, multiple groups of woolen yarn wheels are in wrapped connection to straighten and tension the woolen yarns, and the woolen yarns are treated through a hot steam spray head, an alkali liquor spray head, a softener soaking bucket, a detergent brush head, an acetic acid water spray head and a dry air spray head in sequence. The process fundamentally solves the problem that a woolen yarn fabric is excessively hard; the woolen yarns are straightened through the seven groups of woolen yarn wheels and are subjected to alkali liquor swelling, urea adhesion and softener solution soaking to form composite modified fibers with a softener; and a cam mechanism drives a sliding woolen yarn wheel to float up and down to form a soaking way of snorkeling alternation, thereby improving the softener adsorption efficiency and guaranteeing the woolen yarn resilience.

Description

technical field [0001] The invention relates to the technical field of softening treatment of cotton wool, in particular to a wool modification treatment process for preventing the wool from being too hard. Background technique [0002] Existing fabrics such as cotton wool will harden and deteriorate the fibers of the wool after being worn for a period of time or washed and dried too quickly or stored for too long. After the wool hardens, it will feel hard and not keep warm. , discomfort and other consequences. [0003] When the wool is too hard, if it is directly ironed with an iron, the elasticity of the tissue will be destroyed. At this time, it is best to use a steam iron to spray water on the wrinkles; if the wrinkles are not very severe, you can also hang it up and spray water directly on the wrinkles. After it dries, it will naturally smooth out. [0004] However, the woolen fabric is easily deformed, and after being softened by hot steam or softener, it still has a...

AI Technical Summary

Problems solved by technology

[0004] However, the woolen fabric is easy to deform, and after being softened by hot steam or softener, it still has a large number of repetitions after a period of time, and returns to the wrinkled shape.

The reason is that the softener is always in physical contact with the molecular chain of cellulose. After sunlight or washing, the softener will be detached, and the cellulose will not be able to restore the original soft state after deterioration.
