Embodiment 1

[0020] The preparation method of novel thermal insulation spray cotton is characterized in that, comprises the steps:

[0021] 1) Spray the diluted JX-99 polyester staple fiber oil evenly into the three-dimensional crimped hollow polyester staple fiber in the form of mist, accumulate for 24h-48h, and the oil agent adhesion is 0.3-0.5%; negative ion fiber and kapok fiber Also use the spray method to coat the quaternary ammonium salt oil agent.

[0022] 2) Weigh the treated three-dimensional crimped hollow polyester staple fiber, negative ion fiber and kapok fiber according to the mixing ratio, and respectively pass through the pre-opener for rough opening and impurity removal; among them, high crimp hollow polyester staple fiber, negative ion fiber The mass ratio of fiber and kapok fiber is 9:1:0.5;

[0023] 3) The cotton conveying fan sends the pre-opened three-dimensional crimped hollow polyester staple fiber, negative ion fiber and kapok fiber into the multi-compartment ble...

Abstract

The invention relates to the technical field of polyester wadding, in particular to novel heat-insulating polyester wadding and a preparation method thereof. The novel heat-insulating polyester wadding comprises a matrix and a functional body, fiber flocculus taking high-crimp hollow polyester short fiber as a main body is adopted as the matrix, and a reagent serving as the functional body is sprayed into gaps in the surface and inside the flocculus matrix; the reagent is composed of, by weight, 4-7 parts of sodium alginate, 0.1-0.5 part of calcium chloride, 0.01-0.15 part of surfactant, 15-25parts of binder and 50-65 parts of diluent. The novel heat-insulating polyester wadding has excellent moisture absorptivity and heat insulativity and high fluffiness, is made through carding, glue spraying and special centrifugal process and is suitable for clothes, beddings and household supplies.

Description

technical field [0001] The invention relates to the technical field of spray-coated cotton, in particular to a novel heat-preserving spray-coated cotton and a preparation method thereof. Background technique [0002] Spray-bonded cotton, also known as sprayed wadding, its conventional process is to comb the fiber raw materials into a single-layer thin net, then lay them into wadding, spray adhesive on both sides of the wadding, apply a certain pressure when spraying, and another The vacuum suction on the side makes the adhesive penetrate into the inside of the fiber web, and then after drying and curing, the junction points between the fibers are bonded together. However, when this process is used to produce heavy sprayed cotton over 120 grams per square meter, the depth of the adhesive emulsion sprayed on the surface into the fiber web layer cannot meet the requirements, that is, the fibers and fiber ends floating on the fiber web layer surface The head is bonded by the ad...
