Problems solved by technology

However, because its raw materials need to be imported from Japan and South Korea, the price is expensive
However, most of the non-glue cotton products produced in China cannot meet the requirements of bulkiness, recovery rate, compression rate, etc. due to the limitation of raw materials.

Embodiment 1

[0012] A kind of super-elastic non-glue cotton, the super-elastic non-glue cotton includes the following components by mass percentage: cotton fiber 25%, elastic fiber 15%, hot-melt composite fiber 60%, and the hot-melt composite fiber is made of polyester The polymerization solution spinning of propylene and polybutylene terephthalate is obtained, the mass percent of polypropylene in the described polymerization solution is 15%, and the mass percent of polybutylene terephthalate is 15%, The rest is water.

[0013] Wherein, the elastic fiber is T400 elastic fiber, which has natural permanent spiral crimp and excellent bulkiness, elasticity, elastic recovery rate, color fastness and particularly soft hand feeling, which overcomes the traditional spandex yarn in terms of high temperature resistance, alkali resistance, Disadvantages in chlorine resistance.

[0014] The fiber content of the super-elastic non-glued cotton is 100%, the bulkiness reaches 800-900, the compression rat...

Embodiment 2

[0016] A kind of super-elastic non-glue cotton, the super-elastic non-glue cotton comprises the following components by mass percentage: 30% of cotton fiber, 10% of elastic fiber, 60% of hot-melt composite fiber, and the hot-melt composite fiber is made of polyester The polymerization liquid spinning of propylene and polybutylene terephthalate is obtained, the mass percentage of the polypropylene in the described polymerization liquid is 20%, the mass percentage of polybutylene terephthalate is 20%, The rest is water.

Abstract

The invention discloses super-elastic glue-free wadding. The super-stretch glue-free wadding is made from, by weight, 25-30% of cotton fiber, 10-15% of elastic fiber, and 60-65% of meltable composite fiber. The meltable composite fiber is made by spinning polymer solution of polypropylene and polybutylene terephthalate. The polymer solution contains, by weight, 15-20% of polypropylene, 15-20% of polybutylene terephthalate, and the balance of water. Therefore, the glue-free wadding can be better in elasticity, bulkiness, resilient rate and compression rate; production cost is reduced; the super-elastic glue-free wadding features mould proofing, moth proofing, acid and alkali resistance, water fastness and the like; the super-elastic glue-free wadding contains no chemical bond harmful to human bodies, and is non-toxic, odorless, clean, and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of chemical fibers, in particular to a superelastic non-glue cotton. Background technique [0002] At present, the fillers used in clothing such as cotton clothes, ski jackets and space suits, as well as bedding such as quilts and sleeping bags are mostly spray-bonded cotton, which is fluffy, high in compression resilience, resistant to dry and wet washing, and light in weight and durable. Warmth and other properties are made of natural cotton fibers, man-made fibers or synthetic fibers through stretching, carding, glue spraying, baking and curing. The human body is irritating and does not conform to today's environmental protection concept. [0003] With the advancement of science and technology, a new type of material has been developed - no glue, no need to spray glue, no smell, no stimulation to the human body, it is a kind of non-woven fabric, it is a high-grade material for filling and warmth, with I...
