Production technology for T/R/H multielement functional fiber high textual quality yarn

Abstract

The invention discloses a production technology for T / R / H multielement functional fiber high textual quality yarn. Heterotype cross-section Dacron, functional modified mucilage glue and Han jute fiber are selected as the raw materials or microporous modified dacron, functional modified mucilage glue and Han jute fiber are selected as the raw materials; the raw materials are prepared into clean, neat, puffy, soft, parallel and straight short fiber strands after going through opening and scutching, carding and edulcoration, combing and setting; then drawing decrement is carried out on the Heterotype cross-section dacron short fiber strands or microporous dacron short fiber strands; afterwards the drawing hybrid yarn principle is employed to enable the short fiber strands to be drawn with the functional modified mucilage glue and Han jute fiber; repeated drawing and gilling are performed to realize uniform blending of 3 functional fibers; the fiber strands after being blended and carded is processed into single yarn or plied yarn finished product yarn after going through processes of roving, spun yearn, spooling, doubling and wire twisting.The product of the invention features excellent conformality, bacterial resistance and moisture absorption and perspiration property, thus being an ideal new material of bionic function yarn.

Description

technical field [0001] The invention relates to a production process of T / R / H multifunctional fiber blended high-quality yarn. Background technique [0002] The blended yarn of T / R structure and its wool-like fabric have been introduced in the classic technical reference books of textile textbooks, and they are very popular fashion fabrics in the international textile market in recent years. Among them, "T" stands for polyester fiber and "R" stands for viscose fiber. A large number of literature and experimental data show that the yarn and its fabric of T / R mixed fiber structure make full use of the high elastic modulus of polyester fiber, good shape retention, high strength, durability and softness, smoothness and moisture regain of viscose fiber. High efficiency, moisture absorption and air permeability, and good compatibility with human skin. After blending, the two fibers complement each other and overcome the stiffness of pure polyester fiber fabrics, extremely low moi...

Problems solved by technology

However, the structure and properties of conventional polyester and viscose fibers determine that their blended fabrics still have some technical defects in terms of appearance, texture and wearing comfort, which restricts the further improvement of the grade of chemical fiber wool-like fabrics

For example, it is easy to get aurora due to friction during wearing, the moisture permeability is poor, the feel and comfort are still not comparable to pure wool fabrics, and it does not have antibacterial and health care functions.

With the development of the global economy, material science, and chemical fiber technology, on the one hand, people's clothing concepts and consumption habits have undergone significant changes. , the traditional T / R wool-like fabric has become more and more obvious that it cannot meet the texture and function requirements of modern high-end clothing, especially fashion; on the other hand, due to the application of molecular design theory and bionic technology, the chemical fiber As a result, major changes have taken place in the types, material structures and functions. Various modified and special-shaped cross-section differentiated, functionalized chemical fibers have emerged, and new varieties emerge in an endless stream. For example, cationic dyeable polyester, flame-retardant polyester, "+" Moisture-absorbing and sweat-wicking polyester, microporous polyester, dope dyed luminous polyester, antibacterial viscose, negative ion viscose, far-infrared health care viscose, etc., are high-quality functional T / R The development of new varieties of wool-like fabrics has created conditions
