Dyeing treatment process for pure cotton fabrics based on pure natural biological preparations

The invention discloses a dyeing treatment process for pure cotton fabrics based on pure natural biological preparations, which is designed for solving the technical problems that the environment is seriously harmed in an existing pure cotton fabric dyeing treatment process, and the human health is harmed in an application process. The adopted technical scheme is as follows: the dyeing treatment process comprises the steps of singeing, desizing, boiling-out, bleaching, dyeing, softening treatment and preshrinking treatment, and the key point is that biological preparations, which are respectively a desizing enzyme solution, a boiling-out enzyme solution, glucose oxidase solution and a plant dye, are respectively adopted in the steps of desizing, boiling-out, bleaching and dyeing. The dyeing treatment process has the technical effects that the operation is simple; the pure natural biological preparations almost do not contain any toxic substance, and wastewater produced in the treatment process is less and biodegradable, so that under the premise of keeping the characteristics such as softness, sweat absorption, comfortableness and naturalness and the like of pure cotton fabrics, the harm to the environment is alleviated, and the harm to human body is avoided, and therefore, the process has a zero-pollution environmental friendliness characteristic.

Manufacturing method of novel terylene satin imitated silk fabric

The invention discloses a manufacturing method of novel terylene satin imitated silk fabric. The method comprises the following steps of A. weaving, B. sizing and oil applying, C. desizing and refining, D. alkali peeling, E. finalizing, F. sanding, G printing, H. post-finalizing drying and I. settling. Terylene semi-extinction filaments 75D / 72F are used, satin weave is used as foundation weave, meanwhile, by proper twisting, diffuse reflection phenomena of polyester fibers on light are achieved, metallic luster of triangle isomerism polyester fibers can be weakened and is close to real silk luster, and the draping performance of fabric is improved. By detecting of the heat resistance, the damp obstruction, the wrinkle recovering degree, the static draping degree, friction color fastness, perspiration fastness and saliva resistance color fastness, and novel terylene satin imitated silk fabric completely achieves the effect of real silk.

Stretchable multiple-component nonwoven fabrics and methods for preparing

A method for preparing stretchable bonded nonwoven fabrics which involves forming a substantially nonbonded nonwoven web of multiple-component continuous filaments or staple fibers which are capable of developing three-dimensional spiral crimp, activating the spiral crimp by heating substantially nonbonded web under free shrinkage conditions during which the nonwoven remains substantially nonbonded, followed by bonding the crimped nonwoven web using an array of discrete mechanical, chemical, or thermal bonds. Nonwoven fabrics prepared according to the method of the current invention have an improved combination of stretch-recovery properties, textile hand and drape compared to multiple-component nonwoven fabrics known in the art.

Finishing technology of warp and weft cotton wrapped spandex four-way-stretch easy-care yarn-dyed fabric

The invention discloses a finishing technology of a warp and weft cotton wrapped spandex four-way-stretch easy-care yarn-dyed fabric, and relates to a finishing technology of a cotton type elastic easy-care fabric. The technology comprises the steps of singeing, desizing, mercerizing, washing, preshrinking, high-temperature setting, easy-care finish and baking. An ordinary yarn-dyed fabric production route is changed in the technology process, wherein washing is conducted after mercerizing is conducted, and then sufficient alkali removing can be guaranteed; preshrinking is conducted directly,it is guaranteed that large enough elasticity is achieved in the radial direction. Accordingly, it can be guaranteed that the warp and weft cotton wrapped spandex four-way-stretch easy-care yarn-dyedshirt fabric is produced smoothly, a shirt is made by adopting the warp and weft cotton type elastic easy-care fabric, when people do body movement, limitation does not exist in the four directions, and people feel comfortable and free when wearing the shirt; due to the fact that elastic yarns exist in four directions, after deformation, the elastic yarns can return to the original position, and the aesthetic feeling of being neat in shape is guaranteed.

Polymeric binders having specific peel and cure properties and useful in making creped webs

InactiveUS8012285B2High degree of softness and absorbencyReduce productionShrinkingNon-fibrous pulp additionFiberEmulsion polymerization
This invention is directed to alkylphenol ethoxylate (APE)-free polymer binders formed by aqueous free radical emulsion polymerization and having specific peel and cure properties. The APE-free polymeric binders have a peel value, when adhered to a heated metal surface, of 35% to 200% of the peel value shown by a standard APE-based polymer binder control and exhibit a cure profile such that at least 55% cure is achieved within 30 seconds at a temperature required for cure, and a wet tensile strength at 30-seconds of cure of at least 1000 g / 5 cm. Wet tensile strength is used as a measure of cure. Binders having the peel and cure properties described herein can be considered for use in crepe processes, especially DRC processes.

Stretchable sheet and method for producing the same

A sheet is produced by (i) producing a sheet by entangling woven or knitted material including a thread composed of a composite fiber such that two kinds or more of polyethylene terephthalate polymers different in intrinsic viscosity are stuck together in a side-by-side type along the fiber length direction and/or of a core-in-sheath type composite fiber such that two kinds or more of polyethylene terephthalate polymers different in intrinsic viscosity form an eccentric core-in-sheath structure, with a fiber capable of converting into ultra fine fibers composed of two kinds or more of polymeric substances different in solubility in solvent, (ii) developing an ultra fine fiber with an average single fiber fineness of 0.001 dtex or more and 0.5 dtex or less by treating the sheet with a solvent to thereafter provide elastomer having polyurethane as a main component by impregnating and solidifying solvent solution of elastomer having polyurethane as a main component into the sheet, or of providing elastomer having polyurethane as a main component by impregnating and solidifying solvent solution of elastomer having polyurethane as a main component into the sheet to thereafter develop an ultra fine fiber with an average single fiber fineness of 0.001 dtex or more and 0.5 dtex or less by treating the sheet with a solvent, and (iii) rubbing and shrinking the woven or knitted material under the condition of 110° C. or more.
