Description
Technical field
The utility model relates to a kind of wrap yarn, relates in particular to a kind of dimity wrap yarn that can eliminate hemp fabric prodding and itching feeling, belongs to cover-spinning technical field.
Background technology
Flax fibre is important textile raw material, and its main component is cellulose, and owing to having special morphosis, flax fibre all has good moisture absorption and desorption property, suitable for producing summer clothes fabric.But because flax fibre bending rigidity is large (if the relative bending rigidity of ramee is 9.32 × 10
4cN ﹒ cm
2, be maximum in all common fibers, be even greater than glass fibre 8.54 × 10
4cN ﹒ cm
2), fiber is firm, the fabric being processed into by flax fibre is when wearing next to the skin, be positioned at the filoplume (fibre end) of fabric face owing to bearing larger bending load, when with skin contact, can make skin produce stimulates compared with large depressed deformation the algesiroreceptor that is positioned at skin surface, when this skin depressions stimulation reaches some in the unit are of fabric and skin contact, will cause prodding and itching feeling.Due to the prodding and itching feeling of linen when wearing next to the skin, restricted it as the application that wears next to the skin dress materials, though this is also why flax fibre has the outstanding required moisture absorption and desorption property of summer clothes fabric, but be rarely used in the reason of summer clothes fabric, at present clothes are with linen or mainly as the fabric of non-clothes next to the skin.
Have now several different methods can alleviate and even eliminate in theory the prodding and itching feeling of linen, these methods can be divided into two classes: a class is that softening fabrics improves fabric sofetening degree, and another kind of is the filoplume that reduces to greatest extent fabric face.Reducing the method for hairiness number has: blending, singe, and cropping, filoplume flattening, gluing etc.; The method of soft fabric has alkali or liquefied ammonia degenerative treatments, diluted mineral acid decrement treatment, washing, sand washing, softener processing, cellulase processing etc.The density that flax fibre and other fiber blend can be diluted to the firm flax fibre end of fabric face, if but flax fibre end density will be diluted to prodding and itching feeling in tolerance interval, the blending ratio of flax fibre need drop to very low, and fabric will no longer have style and the wearability of linen.Singe, the method for the minimizing hairiness number such as cropping and length may be to the limitation (cropping) of the damage of fabric body (singing) and processing method itself owing to will taking into account process, can not effectively eliminate prodding and itching feeling, because singe, all can not really remove the hairiness number that can make skin produce depression, triggering algesiroreceptor with cropping, on the contrary due to the shortening of fibre length, cause resisting compared with the increase of macrobending load hairiness number, make prodding and itching feeling stronger.Although feasible in filoplume flattening principle, in practical operation, be difficult to realize the permanent lodging of cloth cover filoplume.The method of gluing (coating) can change permeability and the moisture absorption and desorption property of fabric, has a strong impact on the wearability of linen, generally will not adopt.The method of softening fabrics can not significantly reduce the bending rigidity of fabric face filoplume, because these processing methods can only change the skid resistance between yarn in fabric, and can not change structure and the performance of fiber itself.Therefore, still there is no a kind of method that effectively alleviates and even eliminate linen prodding and itching feeling now.
