Abstract

The utility model relates to composite antibacterial hollow terylene ATY (Airjet Texturing Yarn). The composite antibacterial hollow terylene ATY consists of antibacterial outer yarn and core yarn, wherein the antibacterial outer yarn is wound at the periphery of the core yarn in a continuous closed ring shape; and the antibacterial outer yarn is formed by fibers with hollow cross section. The composite antibacterial hollow terylene ATY has the advantages that the ATY has good three-dimensional structure and bulkiness, the weaved fabric has cotton feel, is full and soft to touch and is good in comfort; and since an inorganic antibacterial agent is adopted for blended spinning and an organic antibacterial agent is adopted for finishing the fiber, the antibacterial performance of the fiber can be improved, the antibacterial spectrum is wide, and the lasting antibacterial effect is achieved; and the fiber is hollow and contains a great amount of still air, the density of the fabric is low, and the heat storage is good. The composite antibacterial hollow terylene ATY can be used for western-style clothes, jackets, coats, down-like clothes, woolen cloth and high-grade bat wool and the like, and also can be widely applied in the aspects of decorative cloth for vehicle cushions, laying decorative cloth for furniture, sleeping bags, blankets and the like.

Description

A kind of composite antibiosis hollow polyester ATY

Technical field

The utility model relates to the functional fibre technical field, specifically, is a kind of composite antibiosis hollow polyester ATY.

Background technology

Improving constantly of Along with people's living standard is not only endurable to the requirement of dress, more pays attention to comfortableness, functionalization, differential be the focus of current fiber industry development.

ATY is an air deformation yarn, is fiber is got into nozzle under the overfeeding state, through the jet action of high pressure, high velocity air; Tow is handed over network processing; Form irregular kink wire ring, make tow have the yarn of fluffy looped pile shape, have good 3-D solid structure and bulkiness; The fabric that is made into has cotton feel, and the plentiful softness of sense of touch, comfortableness are good.The precursor that is used for AIRJET TEXTURING YARN has a variety of, comprises terylene, polyamide fibre, polypropylene fibre, viscose, acetate fibre etc., and these long filaments can be fullly drawn yarn (FDY), pre-oriented yarn or low-oriented yarn etc.ATY has overcome shortcomings such as aurora, the sense of wax shape of synthetic fiber, poor, the easy pilling of breathing freely, and is one of main raw material of emulating fabric.

The Nano Silver based inorganic antibacterial agent has good heat resistance, security, and toxicity is low, pollution is little; Organosilicon-quaternary ammonium salt organic antibacterial agent and fiber surface hydroxyl dehydrating condensation, at fiber surface, antibacterial range is wide, price is low with the covalent bond form fix, and the fiber of back arrangement also possesses good water imbibition, flexibility, antistatic behaviour etc.Adopt inorganic and the organic antibacterial agent acting in conjunction, the fiber antibacterial range is wider, persistence is good.

Though normal polyester ATY has outward appearance and feel preferably; But flexibility, comfortableness deficiency show slightly stiffening, thereby through changing the degree of hollowness that cross sectional shape improves fiber; Expand its scope of application; Utilize organosilicon-quaternary ammonium salt organic antibacterial agent that fiber is carried out the back arrangement, make fiber have good accumulation of heat property and comfortableness, possess stronger antibacterial effect simultaneously again.At present, do not see the report of antibiotic hollow polyester ATY.

The utility model content

The purpose of the utility model is to remedy the deficiency of prior art, satisfies and produces and living needs, and a kind of composite antibiosis hollow polyester ATY is provided.

The purpose of the utility model realizes through following technical scheme:

A kind of composite antibiosis hollow polyester ATY is made up of antibiotic skin yarn and heart yarn, and antibiotic skin yarn is wrapped in the heart yarn periphery with the round of continuous sealing; Described antibiotic skin yarn is that the ATY of hollow shape is fibrous by shape of cross section.The monofilament degree of hollowness of the fiber of described antibiotic skin yarn is 30-35%, and fiber number is 0.5-1.5dpf.

Described inorganic antiseptic is the Nano Silver series antibacterial agent, and organic antibacterial agent is organosilicon-quaternary ammonium salt.

As optimized technical scheme: the degree of hollowness of said fiber is 32%.

Compared with prior art, the good effect of the utility model is:

(1) fiber of the utility model preparation is ATY, has good 3-D solid structure and bulkiness, and the fabric that this fiber is made into has cotton feel, and the plentiful softness of sense of touch, comfortableness are good.

(2) finishing fiber behind this practicality employing Nano Silver based inorganic antibacterial agent co-blended spinning and the organosilicon-quaternary ammonium salt organic antibacterial agent.The Nano Silver based inorganic antibacterial agent has good heat resistance, security, and toxicity is low, pollution is little; Organosilicon-quaternary ammonium salt organic antibacterial agent and fiber surface hydroxyl dehydrating condensation, at fiber surface, antibacterial range is wide, price is low with the covalent bond form fix, and fiber also possesses good hygroscopicity, flexibility, static electricity resistance etc.Adopt inorganic and the organic antibacterial agent acting in conjunction, the fiber antibacterial range is wider, persistence is good.

(3) the utility model fibrous inside hollow, degree of hollowness 30-35%, fibrous inside have comprised a large amount of still airs, and Density is little, has good accumulation of heat property.

The purposes of the utility model:

Can be used for western-style clothes, jacket, overcoat, down-like clothes, woollen goods, high-grade cotton for wadding etc., also be widely used with aspects such as shop decorations cloth, sleeping bag, woollen blankets at vehicle seat pad decorations cloth, furniture.

The specific embodiment

Below in conjunction with specifically being embodiment, further set forth the utility model.Should be understood that these instances only to be used to the utility model is described and be not used in the restriction the utility model scope, be the preferred implementation of the utility model.Should understand in addition; After the content of having read the utility model instruction; Those skilled in the art can make various changes or modification to the utility model under the prerequisite that does not break away from the utility model design, these equivalent form of values fall within the application's appended claims institute restricted portion equally.

As shown in Figure 2, a kind of composite antibiosis hollow polyester ATY of the utility model is made up of antibiotic skin yarn and heart yarn, and antibiotic skin yarn is wrapped in the heart yarn periphery with the round of continuous sealing; Described antibiotic skin yarn is that the ATY of hollow shape is fibrous by shape of cross section, sees Fig. 1.The monofilament degree of hollowness of the fiber of described antibiotic skin yarn is 30-35%, and fiber number is 0.5-1.5dpf.

Below be the preparation process of a kind of composite antibiosis hollow polyester ATY:

Adopt ECDP section and inorganic antiseptic blend melt-spun, fiber cross section is shaped as hollow shape, utilizes the air-texturing process technology, forms ATY, puts in order behind the employing organic antibacterial agent.
