Description
Technical field
The present invention relates to blended spunlace non-woven material of the soft towel of a kind of linen-cotton and preparation method thereof, the flax fiber blending spun lacings
Non-woven material can be used as defending material field.
Background technique
Chinese fiber crops, also known as hemp, hemp, cold fiber crops, fiery fiber crops etc., there is different titles in different regions.China-hemp fibers are derived from work
Industry Chinese fiber crops are widely used because it possesses many excellent performances.China-hemp fibers are one kind most soft in all bast-fibres,
And there is natural bacteriostatic performance, while also having uvioresistant, good moisture absorption to dissipate the functions such as wet, ventilative.Therefore by Chinese fiber crops and
Cotton fiber carries out blended spunlace non-woven material and is highly suitable in terms of defending material.
China-hemp fibers and cotton fiber are all natural fibers, therefore the defects of have many impurity and inconsistent fiber color,
If many impurity will be had without processing product or color seems dirty and seriously affects fabric appearance.Chinese patent Shen
Please (CN20121014251.7) discloses a kind of China-hemp spunlaced non-woven fabric and a preparation method of the fabric and preparation method thereof.This method comprises the following steps:
China-hemp fibers are mixed at least one of long-staple cotton fiber and viscose rayon, then successively through thick shredding, smart shredding, gas
Pressure feeds cotton, combing, lapping, drawing-off, spun lacing and drying steps up to the China-hemp spunlaced non-woven fabric and a preparation method of the fabric.Chinese patent application
(CN20171090629.2) a kind of natural bacteriostatic fibre spun-laced non-woven fabric and its preparation method and application is disclosed, it is described
Natural bacteriostatic fibre spun-laced non-woven fabric includes china-hemp fibers, cotton fiber, and the preparation method comprises the following steps: by Chinese fiber crops
Fiber and cotton fiber are pre-processed respectively；Pretreated china-hemp fibers and cotton fiber are mixed；Composite fibre is successively passed through
Cross opening picking, cotton carding, combing process be made a smart post-tensioning be broken into smart net using hydrophilic treated, shredding, combing, lapping, drawing-off,
Spun lacing, is batched at drying to obtain the final product.But whether undisclosed fiber or product pass through bleaching process, therefore the cleannes of cloth cover will be by
To very big influence.Even if carrying out the pretreatment such as bleaching to fiber before being processed into spun laced fabric, this technique is also more complicated, at
This height.
