Abstract

The invention provides a formula of composite superfine fiber blending liquid. The composite superfine fiber blending liquid comprises nylon and modified polyester, wherein the modified polyester comprises the following components in percentage by weight: 5%-20% of isophthalic acid, 10%-30% of neopentyl glycol and the balance of polyethylene glycol terephthalate. Due to the adoption of the formula, crystals in polyester molecules can be reduced, the crystallization performance of the polyester can be degraded, the boiling shrinkage and the dry heat shrinkage of the polyester are improved, the proportion of added isomers can be adjusted within the weight part range provided by a specification according to different thermal shrinkage requirements, finished cloth treated through the composite superfine fiber blending liquid is very high in fineness, and the gram weight per square meter of the finished cloth can be increased by 30%-40% under the same specification.

Description

technical field [0001] The invention relates to a formulation of a composite ultrafine fiber blended liquid, in particular to a formulation of a split-type high-shrinkage composite ultrafine fiber blended liquid. Background technique [0002] Conjugate fibers, also known as conjugate fibers, are composed of two components, which can be polyester (PET), polyamide (PA), polypropylene (PP), polyethylene (PE), polystyrene Ethylene (PS) and their modified high polymers. The composite form can be divided into five categories according to the cross-sectional shape: co-spun type, side-by-side type, sheath-core type, split type and island-in-the-sea type. Composite microfiber is widely used in clothing, high-grade artificial leather, adsorption and filter materials due to its advantages such as high coverage, soft hand feeling, comfortable wearing, and excellent adsorption, and has become a popular fiber variety. Composite ultra-fine fiber has fine monofilament fineness (generally ...
