Method for increasing weight and bulkiness of silk floss

Abstract

The invention discloses a method for increasing weight and bulkiness of silk floss. The method comprises the steps of preparing the silk floss; degumming the silk floss; washing the silk floss; increasing weight of the silk floss; bulking and cleaning the silk floss; and drying the silk floss. The weight increasing process is as follows: preparing working solution, dissolving the working solution, adding the silk floss, soaking for 10min at room temperature; rising temperature to 80 DEG C with speed of 1 DEG C / min, continuously reacting for 90 min; performing water washing; removing the working solution; and performing water washing for 10min at room temperature, wherein the working solution comprises a composite of acrylamide substances and methacrylate substances, potassium peroxydisulfate, formic acid, non-ionic surfactant Tween 80 and calcium chloride, a mass ratio of the acrylamide substances and the methacrylate substances is 4: 1 to 9: 1, and the adding amount of the composite is 15-20% of the silk floss; the adding amount of the potassium peroxydisulfate is 4% of the composite; the adding amount of the formic acid is 3g / L; the dosage of the Tween 80 is 0.5g / L; and the dosage of the calcium chloride is 40g / L and liquor ratio is 1: 15;. The method disclosed by the invention finally increases weight by about 7-10%.

Description

technical field [0001] The invention belongs to the technical field of textile chemistry, and in particular relates to a treatment method for increasing the weight and fluffing of silk floss. Background technique [0002] Silk floss is a flocculent product processed from silkworm cocoons, tussah silkworm cocoons or by-products of silk reeling. It has the unique advantages of softness, comfort, warmth and elasticity. Clothes and quilts are high-end health care products. popular with consumers. [0003] Silk floss is a kind of non-woven natural protein fiber. After degumming, entanglement and adhesion between fibers are easy to occur, which will cause a decrease in elasticity and warmth retention, and a large loss of quality after degumming. While adding weight to the silk floss, it can also improve the smoothness and bulkiness of the silk floss fibers. [0004] At present, there are many methods for fluffing silk cotton. For example, the invention patent application CN10192...

Problems solved by technology

[0004] At present, there are many methods for fluffing silk cotton. For example, the invention patent application CN101926581A disclosed on December 29, 2010 discloses a method for making a fluffy and warm silk quilt, and the invention patent ZL200610050727.6 disclosed on October 11, 2006 provides A kind of preparation method of elastic silk floss is proposed, but the weight of silk floss cannot be increased after the fluffy treatment, and the processing method of weight-increasing silk fiber mostly focuses on the real silk yarn or fabric after degumming is carried out weight-increasing, as published on May 24, 2006 The invention patent ZL200510122797.3 disclosed the weight gain method after cocoon silk degumming, and the invention patent ZL200510040766.3 published on November 9, 2005 provided a method for plasma grafting of silk fibers to increase weight, December 31, 2008 Published invention patent ZL200810063454.8 discloses a method for increasing the weight of silk by using the sol-gel method to fix sericin. Since silk floss is a non-woven loose fiber, it is easy to entangle and stick between fibers. According to the increase of silk yarn or fabric Heavy process for weight gain, easy to cause uneven weight gain, thick fiber after weight gain, bad hand feeling, poor fluffiness
