Abstract

The invention discloses milk protein blending regenerating cellulose fiber, and a preparation process and application thereof. The process comprises the following steps of: (1) pulping; (2) dipping; (3) squeezing and crushing; (4) ageing; (5) yellowing; (6) dissolving; (7) ripening; (8) preparing milk protein spinning solution; (9) spinning; and (10) performing aftertreatment to obtain a finished product. The milk protein blending regenerating cellulose fiber can be used for preparing viscose short fiber and viscose filament yarn and has the characteristics of skin affinity, skin-nourishing property, moisture absorption, air permeability, soft handfeel, gloss, brightness, luxury appearance, excellent physical and mechanical properties and the like.

Description

technical field [0001] The invention belongs to the technical field of cellulose fibers, and more specifically relates to a milk protein blended regenerated cellulose fiber and its preparation process and application. Background technique [0002] Milk protein fiber contains more than ten kinds of proteins and amino acids that are beneficial to the human body. Through the moisturizing factor, it can always protect, maintain and moisturize the skin of the human body. [0003] In addition, milk protein fiber and its filaments are high-grade new fiber materials. It combines the advantages of natural protein fiber and chemical fiber. It has excellent mechanical properties and good spinnability. However, the immaturity of milk protein fiber and fabric preparation technology has always restricted and affected its application and promotion in the textile industry. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the prio...
