Description
Technical Field
The invention relates to an ultra-soft pure cotton wide woven fabric and a production method thereof, belonging to the technical field of dyeing and finishing.
Background
Cotton fibers have natural softness due to the oil wax, but after processing such as scouring, bleaching, dyeing and the like or functional finishing, cotton fabrics become rough due to the removal of the oil wax and damage to the fibers, and even the sewing performance is affected, so the soft finishing is often needed. The production is usually finished by cellulase and chemical softener. When the cellulase is used for finishing, local strong damage is possibly caused to be excessive, so that the quality of the product is reduced. Chemical softeners have been widely used to soften fabrics and also act as fiber lubricants, reducing fiber-to-fiber friction and improving fabric drape and wearability. However, chemical softeners also have some problems in terms of environmental safety and the like. After the 90% cotton and 10%90 ℃ water-soluble vinylon blended yarn woven fabric is subjected to dyeing and finishing processing, 10% water-soluble vinylon is completely hydrolyzed into small molecules to be dissolved and removed, the yarn fineness is increased, the yarn twist is reduced, and the softness of the fabric is greatly improved.
