A kind of yarn and its production method containing three-dimensional structure
Technical field
The present invention relates to a kind of field of textiles, more particularly to a kind of yarn and preparation method thereof containing three-dimensional structure.
Background technique
In the prior art for soluble vinylon fiber using more.
As patent 201810089492.4 provides a kind of mixed yarn and preparation method thereof.The mixed yarn includes to mix mutually
Miscellaneous soluble vinylon fiber component and main fibre component;The matter of the soluble vinylon fiber component and main fibre component
Amount is than being (5~80):(20~95).The mixed yarn that invention provides includes the soluble vinylon fiber component and main body adulterated mutually
Fibre fractionation, dissolves water-soluble fibre after being made into fabric, and yarn interior gap increases, generate more middle null point and
Groove, line density reduce, and still air increases, so that fabric is light and soft.
For another example 201711262532.2 patents of invention disclose a kind of processing method of thermal fabric, are related to a kind of thermal surface
The processing method of material, including:(1) outer wrapping fiber selects cotton fiber, the polyvinyl long filament of cored silk selection high-dissolvability and low dissolution
The polyvinyl long filament of degree, is then made rove;Spun yarn is carried out using RING SPINNING cored yarn process, finally obtains covering yarn;It adopts simultaneously
Solid cotton yarn is spinned with same draft process in case using;(2) select three on once twill left to right tissue weaved, Warp Tension Test with
Bringer sequence is all made of covering yarn and is alternatively arranged with solid cotton yarn, obtains fabric;(3) gained fabric is subjected to water-soluble processing, made
Fabric moves back dimension, obtains hollow yarn;It finally dries, obtains thermal fabric.
For another example the utility model patent of 201720913586.X functional composite fabric discloses a kind of functional composite fabric,
The functional composite fabric includes the functional layer of ontology and body surface, and the ontology is made of warp thread and weft yarn, institute
Stating warp thread is that tencel, wood-fibred, cashmere and spun silk are twisted in the shape of a spiral, and the weft yarn is vinylon fibre and viscose rayon
It twists together with, the fineness of the ontology is 18-25tex.The utility model provides a kind of functional composite fabric, is provided with remote
The function of infrared ray, and there is gas permeability and warmth retention property possessed by cotton, animal origin, it is comfortable and easy to wear, to human body without pair
Effect.
Invention disclosed above patent and utility model patent are the disadvantage is that water soluble vinylon used is two-dimensional surface knot
Structure is formed by hollow less than normal, hollow rate is much too late by being also planar structure after blended resultant yarn after subsequent dissolution
Three-dimensional space it is big, the gas permeability that can improve fabric and warmth retention property declared influence limited.

Disclosed herein as well is a kind of fabrics prepared by yarn described above.
Disclosed herein as well is it is a kind of using after yarn weaving as described above after dyeing process removes Soluble Fiber
The fabric of acquisition.
Technical scheme has the advantages that:
The invention patent discloses a kind of yarn, which is made of two or more different fibrous materials, in these groups
At the fiber that in the material of yarn, there are one or more of solubilities, and these soluble fibres have the non-straight of curling simultaneously
Three-dimensional structure, yarn by the combing of Weaving device and applies longitudinal pulling force along machine direction in fabrication processes
So that the fiber in yarn becomes straight, but there is fiber the trend back to rolled state to release after fibre spinning
Longitudinal pulling force is put, Yarn-recovery, fiber restores or part is restored to original three-dimensional crimp state, generates a part of fluffy soft
Soft effect, further, yarn dissolves away Soluble Fiber under certain conditions, due to the disappearance of soluble crimped fibre, hair
Raw more yarn stress releases and the fluffy soft effect of further retraction for generating yarn, simultaneously as soluble curling is fine
The disappearance of dimension generates the space generated by the disappearance of Soluble Fiber in yarn interior, so that the fluffy pliability of fiber is again
One step improves.To generate a kind of special soft yarn with three-dimensional structure.Fabric made from such yarn has fluffy soft
Soft feel, excellent ventilative, moisture pick-up properties.
