Problems solved by technology

The padding-baking-baking process is a traditional anti-wrinkle finishing process. The resulting fabric has the problems of hard hand feeling and large loss of strength, which has a certain adverse effect on the wearability of the garment, and the padding method uses a large amount of finishing agent, and the padding method The liquid-carrying rate of the finished fabric is high, resulting in high energy consumption for pre-drying and baking, which is not in line with the concept of green environmental protection and economical saving
However, due to the complex process and long process time of foam finishing and moisture crosslinking, their promotion has been affected.

Abstract

The invention relates to a crease-resistant finishing method for point-like crosslinked fabric based on a spraying method. Precisely-controllable spraying equipment is utilized to uniformly spray a crease-resistant finishing agent on the fabric at a certain dimension and at a certain interval, uniform dense uncontinuous crosslinked points are formed in the fabric after thermal processing and / or electron-beam irradiation are / is performed, so that the point-like crosslinking structure is formed. The crosslinking points fix molecular chains, prevent large slippage of the molecular chains and provide crease resistance for the fabric. Certain relative movable capability is provided between the molecular chain segments among crosslinking points and fiber, so that the fabric is endowed with softness and high tensile-strength retention rate, and the tensile-strength reduction phenomenon easily caused by routine fabric crease-resistant finishing method is prevented. The provided method has the advantages of being simple in operation, high in processing efficiency, green and environment-friendly, and high in economic benefit. The prepared product is good in crease resistance, soft in handfeeling, free of obvious reduction on tensile strength and good in tensile-strength retention rate, and is applicable to clothes, bedding articles and the like.

Description

technical field [0001] The invention relates to a method for anti-wrinkle finishing of fabrics based on point-like cross-linking by a spray method, and belongs to the technical field of textile post-finishing. Background technique [0002] The high-paced work and lifestyle in modern society put forward high requirements for the easy-care performance of clothing. Clothing is required to have good wrinkle resistance and remain flat after washing without affecting the appearance. Therefore, some fabrics with poor wrinkle resistance themselves need to be wrinkle-resistant before being made into clothes. [0003] Relative slip between fiber molecular chains is an important reason for fabric wrinkles. Pure spinning and blended fabrics of cotton, wool, silk, linen, viscose and other fibers are prone to wrinkles. The principle of anti-wrinkle finishing is mainly to fix the relative position of molecular chains, prevent and reduce the slippage between molecular chains. [0004] T...
