Abstract
The utility model discloses a thermosensitive shape memory fabric which is woven by warp yarns and weft yarns. Either the warp yarns or the weft yarns adopt shape memory yarns and the shape memory yarns adopt shape memory coating yarns or core-spun yarns. The thermosensitive shape memory fabric provided by the utility model has specific fabric compactness, under ordinary temperature, the fabric has fixed initial state while after long-term placing or wearing, wrinkles and deformation are generated, and the fabric can be easily returned to the initial form after being treated under heat condition near the deformation recovery temperature of the fabric. Compared with the prior art, the fabric has higher shape fixing rate and shape recovery rate.
Description
Technical field
The utility model relates to field of textiles, relates in particular to the temperature-sensitive shape memory fabrics that a kind of shape memory yarn and other yarns interwoven form.
Background technology
The temperature-sensitive shape memory is meant and has initial configuration that the goods of (playing primary state) after (deformation states) fixed in deformation, can recover the characteristic of its original shape again by the effect of heat.The temperature-sensitive shape memory fabrics is meant the fabric with temperature-sensitive shape memory that utilizes shape memory yarn that shape memory long filament or staple fibre yarn be spun into to be interwoven with other yarns or long filament again.This fabric with initial configuration is after deformation is fixing, and the effect by certain heat can recover its initial configuration again.The temperature-sensitive shape memory fabrics plays an important role in fields such as biomedical, weaving dress ornament, toy, packing, defence and militaries.
Fabric compactness comprises that through, broadwise tightness be coverage coefficient, is meant the ratio of the average centre distance through between, weft yams diameter and two warps, weft yarn.The tightness of fabric influences outward appearance, the feel of fabric to a great extent.
Summary of the invention
The utility model provides a kind of memory effect good, and is powerful higher, the temperature-sensitive shape memory fabrics that COLOR FASTNESS is good.
A kind of temperature-sensitive shape memory fabrics, being interweaved by warp thread and weft yarn constitutes, and at least one is a shape memory yarn in described warp thread and the weft yarn.
Described shape memory yarn is shape memory wrap yarn or cladded yarn.
Be described temperature-sensitive shape memory fabrics:
(a) formed by shape memory yarn and other yarns interwoven, wrap yarn or cladded yarn both can be used as warp thread, also can be used as weft yarn; Described other yarn raw materials can be cotton, fiber crops, silk, hair or chemical fibre;
Or (b) warp thread and weft yarn are shape memory wrap yarn or cladded yarn.
Shape memory wrap yarn described in the utility model is meant that with temperature-sensitive shape memory polyurethane long filament be heart yarn, and other yarns of outsourcing or long filament form, and the raw material of other yarns or long filament can be cotton, fiber crops, hair, silk or chemical fibre.
Shape memory cladded yarn described in the utility model is meant that with temperature-sensitive shape memory polyurethane long filament be heart yarn, and other fibers of outsourcing form, and the raw material of other fibers can be cotton, fiber crops, hair, silk or chemical fibre.
Ratio as the average centre distance between preferred described warp diameter and adjacent two warp thread is 60%～95%; The ratio of the average centre distance between described diameter of the weft yarn and adjacent two weft yarns is 45%～60%.
The ratio of the average centre distance between described warp diameter and adjacent two warp thread is the warp-wise tightness, the ratio of the average centre distance between described diameter of the weft yarn and adjacent two weft yarns is the broadwise tightness, and suitable tightness helps improving the fixed in shape rate and the shape recovery ratio of fabric.
As further preferred, when the ratio of warp-wise tightness and broadwise tightness is 1.5～2: in the time of between 1, the shape memory effect of fabric is better, especially when fabric when broadwise tightness ratio reaches 1.75: 1 left and right sides, shape memory effect the best of fabric, the fixed in shape rate of fabric reaches more than 86%, and shape recovery ratio reaches more than 82%, this moment, the intensity of fabric was higher, and the outward appearance of fabric, feel are all better.
The utility model temperature-sensitive shape memory fabrics has specific fabric compactness, has fixing initial configuration at normal temperatures, process produces the fold distortion when placing for a long time or wearing, this fabric placed under near its deformation recovery temperature the heat condition handle, this fabric recovers its initial configuration at an easy rate, and its fixed in shape rate of prior art and shape recovery ratio all are greatly improved relatively.
